  • Ductal adenocarcinoma of the prostate is an unusual subtype that may be associated with a more aggressive clinical course, and is less responsive to conventional therapies than the more common prostatic acinar adenocarcinoma.
  • However, given its frequent association with an acinar component at prostatectomy, some have challenged the concept of prostatic ductal adenocarcinoma as a distinct clinicopathologic entity.
  • We studied the occurrence of the TMPRSS2-ERG gene fusion, in 40 surgically resected ductal adenocarcinoma cases, and in their associated acinar component using fluorescence in situ hybridization.
  • A group of 38 'pure' acinar adenocarcinoma cases matched with the ductal adenocarcinoma group for pathological grade and stage was studied as a control.
  • Compared with the matched acinar adenocarcinoma cases, the TMPRSS2-ERG gene fusion was significantly less frequently observed in ductal adenocarcinoma (45 vs 11% of cases, P=0.002, Fisher's exact test).
  • Here, of the ductal adenocarcinoma cases with the gene fusion, 75% were fused through deletion, and the remaining case was fused through translocation.
  • The TMPRSS2-ERG gene fusion was also rare in the acinar component of mixed ductal-acinar tumors when compared with the pure acinar adenocarcinoma controls (5 vs 45%, P=0.001, Fisher's exact test).
  • In 95% of the ductal adenocarcinoma cases in which a concurrent acinar component was analyzed, there was concordance for presence/absence of the TMPRSS2-ERG gene fusion between the different histologic subtypes.
  • In the control group of pure acinar adenocarcinoma cases, 59% were fused through deletion and 41% were fused through translocation.
  • The presence of the TMPRSS2-ERG gene fusion in some cases of prostatic ductal adenocarcinoma supports the concept that ductal adenocarcinoma and acinar adenocarcinoma may be related genetically.
  • However, the significantly lower rate of the gene fusion in pure ductal adenocarcinoma cases underscores the fact that genetic and biologic differences exist between these two tumors that may be important for future therapeutic strategies.

  • [Title] Aberrant methylation and loss of expression of O-methylguanine-DNA methyltransferase in pulmonary squamous cell carcinoma and adenocarcinoma.
  • The methylation status of the MGMT gene was investigated by methylation-specific polymerase chain reaction (PCR) and expression status was investigated by immunohistochemistry in 70 cases of pulmonary squamous cell carcinoma (pulmonary SqCC), including 23 cases of the central type and 47 cases of the peripheral type, and in 53 cases of the peripheral type of pulmonary adenocarcinoma (AC).
  • In AC with mixed subtypes showing MGMT methylation, the level of MGMT expression in the bronchioloalveolar carcinoma (BAC) area (non-invasive status) was significantly higher than that in the papillary or acinar AC area (invasive status; P = 0.0002).
  • This trend was not found in AC with mixed subtypes showing no MGMT methylation (P = 0.10).

  • [Title] Enhanced expression of peroxisome proliferator-activated receptor gamma in epithelial ovarian carcinoma.
  • This study demonstrates the relative expression of PPARgamma in normal ovaries and different pathological grades of ovarian tumours of serous, mucinous, endometrioid, clear cell and mixed subtypes.
  • In contrast, 26 out of 28 carcinomas studied were positive for PPARgamma expression with staining confined to cytoplasmic and nuclear regions.
  • On the other hand, predominant cytoplasmic staining was observed in lower-grade tumours.
  • These findings suggest an involvement of PPARgamma in the onset and development of ovarian carcinoma and provide an insight into the regulation of this molecule in the progression of the disease.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • The significance of the relative expression of both ER subtypes in endometrial adenocarcinomas remains to be clarified and the usefulness of the determination of the receptor status in endometrial cancer patients is still controversially discussed.
  • Pathological and surgical records of 214 patients who were diagnosed with an endometrioid adenocarcinoma without other histological types (including mucinous, mixed, squamous or villoglandular differentiation) were reviewed for both estrogen receptors.
  • However, ER-alpha and ER-beta were not independent factors with survival in endometrial adenocarcinoma patients.
  • Therefore, the analysis of both estrogen receptors might be used as a marker to identify high-risk patients only in a subset of patients with endometrioid adenocarcinoma.

  • Ovarian atypical proliferative (borderline) mucinous tumors of gastrointestinal and seromucinous types are considered subtypes within the mucinous tumor category despite the presence of distinctive clinicopathologic features that seromucinous tumors share with pure serous tumors.
  • The gastrointestinal and seromucinous types of atypical proliferative mucinous tumors are immunophenotypically distinctive tumors.
  • Expression of the latter markers in the seromucinous tumors, which also are expressed in pure serous tumors, and lack of expression of gastrointestinal-type markers, combined with the clinicopathologic features these tumors share with pure serous tumors, support the concept that this subtype is more closely related to serous than gastrointestinal type mucinous tumors and justify the designation "seromucinous.

  • [Title] Micropapillary pattern: a distinct pathological marker to subclassify tumours with a significantly poor prognosis within small peripheral lung adenocarcinoma (</=20 mm) with mixed bronchioloalveolar and invasive subtypes (Noguchi's type C tumours).
  • AIMS: A micropapillary pattern (MPP) in lung adenocarcinoma, characterized by papillary structures with epithelial tufts lacking a central fibrovascular core, has been reported to be a new pathological marker of poor prognosis.
  • A new histological classification of small lung adenocarcinoma proposed by Noguchi et al. has been found to be useful since it has defined surgically curable bronchioloalveolar carcinoma (BAC)-type tumours (Noguchi's type A and B) based on the absence of active fibroblastic proliferation.
  • However, BAC-type tumours with active fibroblastic proliferation (Noguchi's type C), which is adenocarcinoma with mixed subtypes including BAC and invasive carcinoma in the new World Health Organization (WHO) classification, account for most of the small adenocarcinomas and represent a heterogeneous group ranging from minimal to overtly invasive cancer with variable prognoses.
  • Therefore, in this study the aim was to investigate whether MPP can be an additional histological marker(s) to subclassify this heterogeneous group in small lung adenocarcinoma.
  • The 5-year survival rates of BAC (Noguchi's type A and B) (n=14), mixed BAC and invasive adenocarcinoma (Noguchi's type C) (n=85) and invasive adenocarcinoma (Noguchi's type D and F) (n=23) were 100%, 68% and 36%, respectively.
  • In patients with mixed BAC and invasive adenocarcinoma (Noguchi's type C tumours), the 5-year survival of the MPP-positive group (n=51) was 54%, significantly lower than that of the MPP-negative group (n=23) of 100% (P=0.02).
  • CONCLUSIONS: MPP is a simple and distinct pathological marker to subclassify tumours with a significantly poor prognosis within small (</=20 mm) mixed BAC and invasive adenocarcinoma (Noguchi's type C tumours).

  • [Title] Lung adenocarcinoma: modification of the 2004 WHO mixed subtype to include the major histologic subtype suggests correlations between papillary and micropapillary adenocarcinoma subtypes, EGFR mutations and gene expression analysis.
  • The histologic heterogeneity of lung adenocarcinoma creates a variety of complex challenges to pathologists in analyzing the various subtypes.
  • We analyzed 100 cases for clinical, pathologic, and molecular features using a modification of the 2004 World Health Organization (WHO) classification to record the major component in the mixed subtype tumors.
  • The most common major histologic subtype was papillary (37%) followed by acinar (30%), solid (25%) and bronchioloalveolar (7%) carcinoma (BAC), although no pure BACs were seen.
  • Papillary adenocarcinoma strongly correlated with EGFR mutation (P<0.001) and gene profile Cluster 1 (P=0.006) with weaker correlations with low grade (P=0.038) and favorable behavior in Stage 1 patients (P=0.047).
  • Solid adenocarcinoma strongly correlated with gene profile Cluster 3 (P=0.001) and worse survival (P=0.001).
  • Our data suggest that EGFR mutations are associated with papillary adenocarcinoma and gene profile Cluster 1.
  • We discovered this only because we used a comprehensive approach examining in detail all histologic subtypes and we modified the 2004 WHO mixed subtype to include the major histologic subtype.
  • Such an approach should be considered in future studies for validation in other datasets.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • OBJECTIVE: In this retrospective study, we clarified the impact of smoking on prognosis and the association of clinicopathological factors, particularly histologic subtype, in patients with small adenocarcinoma of the lung.
  • These subtypes are bronchioloalveolar carcinoma (BAC), adenocarcinoma with little or no BAC component (Non or min BAC), and mixed bronchioloalveolar carcinoma with other adenocarcinoma components.
  • The prevalence of smoking by histologic subtype was 27.3% for BAC, 43.2% for mixed bronchioloalveolar carcinoma, and 74.6% for Non or min BAC.
  • Furthermore, the smoking index (daily cigarette consumption times years of smoking) was significantly higher in Non or min BAC than in the other two subtypes.
  • In addition, patients with a high smoking index showed a greater percentage of Non or min BAC subtypes.
  • CONCLUSIONS: When adenocarcinomas were small (diameter </=2 cm) cigarette smoking and male gender were associated with Non or min BAC histologic subtypes, which are thought to have more aggressive biologic features resulting in poorer outcome compared with other subtypes.

  • Five IPMNs revealed invasive adenocarcinoma, including a colloid carcinoma from an IN type epithelium.
  • Mixed histology was common.
  • K-ras mutations were most common, but did not correlate with dysplasia. p53 mutations were seen in 6% of cases (only in GF and PB subtypes).
  • These findings suggest the possibility of alternate pathways for carcinogenesis between epithelial subtypes of IPMNs.

  • [Title] Surgery for bronchioloalveolar carcinoma and "very early" adenocarcinoma: an evolving standard of care?
  • Nevertheless, recent lung cancer screening studies have led to the detection of an increasing number of "very early" NSCLC (defined as less than 2 cm in size) and of good-prognosis histologic subtypes, bronchioloalveolar carcinoma (BAC), and adenocarcinoma (AC), mixed subtypes that are potentially appropriate for sublobar resection.
  • The precise indications for sublobar resection remain unclear and are the subject of ongoing clinical trials, but it seems that very early, peripherally located, node-negative AC of a predominantly BAC pattern may be adequately treated in this manner.

  • Mucinous carcinoma of the breast is a relatively rare histologic type with two subtypes: pure and mixed.
  • The prognosis for pure mucinous carcinoma (PMC) was much better than for the mixed mucinous carcinoma (MMC).
  • The aim of the study is to determine suitable candidates for breast or axillary conservation in mucinous carcinoma subtypes.
  • The slides of 26 pure and 23 mixed mucinous carcinomas of the breast were evaluated.
  • In conclusion, MMC had worse prognostic factors than PMC with both types of mucinous carcinoma showing similar ER and PR positive status.

  • In 1996, the World Health Organization distinguished two different types of mucinous cystic tumors: intraductal papillary mucinous neoplasms (IPMNs) of the pancreas, which are characterized by mucin production, cystic dilation of the pancreatic ducts, and intrapapillary growth, and mucinous cystic neoplasms (MCNs), which are defined by ovarian-like stroma and in most cases do not communicate with pancreatic ducts.
  • Further, IPMNs can be subdivided into main-duct type, mixed-type, and branch-duct type tumors.
  • Histopathologically, both IPMNs and MCNs demonstrate a wide spectrum of cellular atypia ranging from mild mucinous hyperplasia to invasive adenocarcinoma.
  • Because mucinous cystic neoplasms of the pancreas show significant differences in clinical behavior from patient to patient, knowledge of the clinicopathologic characteristics and natural history of specific subtypes of IPMNs and MCNs has become crucial for physicians working in the field of gastroenterology.

  • [Title] Loss of expression of E-cadherin and beta-catenin is associated with progression of pulmonary adenocarcinoma.
  • The aim of the present study was to determine the association of loss of membranous expression of epithelial (E)-cadherin and beta-catenin with the progression of pulmonary adenocarcinoma.
  • The expression of E-cadherin and beta-catenin was examined in 154 cases of pulmonary adenocarcinoma, including 49 cases of atypical adenomatous hyperplasia (AAH), 40 cases of bronchioloalveolar carcinoma (BAC), 42 cases of BAC-dominant type of adenocarcinoma with mixed subtypes (early MX) and 23 cases of BAC-recessive type of adenocarcinoma with mixed subtypes (overt MX), by immunohistochemistry.
  • Loss of expression of E-cadherin and beta-catenin may play an important role in the progression of pulmonary adenocarcinoma, and these events occur before structural destruction of the alveolar wall by invasion of carcinoma cell.

  • [Title] Prognostic significance of a histologic subtype in small adenocarcinoma of the lung: the impact of nonbronchioloalveolar carcinoma components.
  • BACKGROUND: We tried to clarify whether the histologic subtypes and the size of the solid component of an adenocarcinoma are more important predictive factors for invasiveness or prognosis than is total tumor size, even in lung adenocarcinomas that were 2 cm or smaller.
  • METHODS: Between 1996 and December 2005, after standard surgical treatment, 82 patients were diagnosed as having adenocarcinoma with a maximum diameter of 2 cm or less.
  • The clinicopathologic records of the patients were examined with regard to age, sex, nodal status, tumor size (largest diameter of the total tumor as well as the largest diameter without the bronchioloalveolar carcinoma [BAC] component [solid component]), serum carcinoembryonic antigen level, and histologic type.
  • Histologic subtype was classified into two groups: mixed BAC (mixed adenocarcinoma with BAC) and minimal or non-BAC (tumors with little or no BAC component).
  • However, diameter excluding the BAC component was a significant factor for invasiveness in mixed BAC type (p = 0.035), whereas total diameter was not significant (p = 0.28).
  • The 5-year survival rate was 94.4% (94.1% for pN0) for the mixed BAC type and 71.4% (78.7% for pN0) for the minimal or non-BAC type (p = 0.009; p = 0.04 for pN0 nodes).
  • The first category is a minimal or non-BAC adenocarcinoma that shows aggressive biological behavior.
  • The second category is a mixed BAC, which demonstrates less invasive or aggressive biological behavior than the minimal or non-BAC type, with the degree of invasiveness being associated with the size of the non-BAC component.

  • [Title] Gene amplification and protein expression of EGFR and HER2 by chromogenic in situ hybridisation and immunohistochemistry in atypical adenomatous hyperplasia and adenocarcinoma of the lung.
  • AIMS: To investigate the importance of gene amplification and EGFR (epidermal growth factor receptor) and HER2 protein expression during the progression of adenocarcinoma of the lung.
  • METHODS: EGFR and HER2 gene amplification was examined in atypical adenomatous hyperplasia (AAH), bronchioloalveolar carcinoma (BAC), and adenocarcinoma with mixed subtypes (MX) by chromogenic in situ hybridisation (CISH), and protein expression was examined by immunohistochemistry using paraffin wax embedded tissues.
  • Because EGFR and HER2 protein expression was frequently seen without gene amplification, other mechanisms apart from gene amplification may be associated with protein expression.
  • CONCLUSIONS: EGFR and HER2 gene amplification may be a late event and EGFR and HER2 protein expression may be associated with the development of adenocarcinoma of the lung.

  • TTF-1 has been used as a reliable lineage marker for lung adenocarcinoma and thyroid carcinoma in surgical pathology.
  • However, TTF-1 expression has been recently reported in carcinomas of other origins including female genital tract.
  • By using SPT24/Refine/Bond Max, TTF-1 reactivity could be detected in all major histologic subtypes of gynecologic tumors and up to 26% of all cases tested on routine surgical specimens and 6.4% on TMA.
  • TTF-1 was most frequently detected in uterine malignant mixed Müllerian tumor (82%), more common in uterine tumors than ovarian tumors, and more common in surgical specimen than TMA.

  • All tumors had a heterogeneous echotexture and a distinct appearance when compared with the typical appearance of adenocarcinoma when viewed via EUS.
  • Patients with pleomorphic giant cell tumors of the pancreas had a poor clinical course with a rapid decline, whereas those with mixed or osteoclastic giant cell tumors tended to have a better outcome, with a greater long-term survival.
  • The risk factors for these lesions may be different from those associated with pancreatic adenocarcinoma.
  • Some giant cell tumor subtypes may carry a more favorable prognosis than pancreatic adenocarcinoma, and awareness and recognition of these differences can affect patient care.

  • [Title] Immunohistopathological re-evaluation of adenocarcinoma of the lung with mixed subtypes using a tissue microarray technique and hierarchical clustering analysis.
  • To re-evaluate adenocarcinoma, mixed subtypes (ADMIX) of the lung, a total of 201 cases were classified into three main subgroups according to the most differentiated histological growth pattern; namely bronchioloalveolar carcinoma (BAC)-mixed, which was the most predominant (73.1%), papillary (PAP)-mixed (21.9%), and acinar-mixed (5%).
  • The PAP-mixed was significantly male predominant and had more progressed clinicopathological features.
  • Hierarchical clustering analysis was separately applied to the immunohistochemical results of ADMIX and ADMIX subgroups, and it was found that most acinar-mixed cases were placed in a separate cluster, while the BAC-mixed and PAP-mixed failed to form significant independent clusters.
  • The antibody clustering profile for the acinar-mixed was clearly different from that for the BAC-mixed or PAP-mixed, but the PAP-mixed shared a dendrogram profile with the other two subgroups.
  • In conclusion, ADMIX can be classified into three histopathological subgroups according to the most differentiated growth pattern, of which a PAP growth pattern might indicate more aggressive behavior than that of a BAC growth pattern.

  • [Title] Magnetic resonance imaging in peripheral lung adenocarcinoma: correlation with histopathologic features.
  • This study retrospectively evaluated the efficacy of newer MRI techniques for differentiating among the different types of invasiveness in lung adenocarcinoma by comparing the MRI findings with the pathologic findings.
  • MATERIALS AND METHODS: From May 2005 to April 2007, 46 patients with lung adenocarcinoma measuring 3 cm or less across the greatest dimension underwent a surgical operation including preoperative MRI study in this hospital.
  • RESULTS: Of all the tumors, 13 were bronchioloalveolar carcinoma (BAC), 24 were adenocarcinomas with mixed subtypes (advanced BAC), and 9 were other histologic subtypes (non-BAC).
  • CONCLUSIONS: DWI could therefore be a useful diagnostic modality for differentiating the subtypes of lung adenocarcinomas, and the MRI finding may thus provide useful supplementary information before surgery comprising limited resections.

  • [Title] Is nonsmall cell type high-grade neuroendocrine carcinoma of the tubular gastrointestinal tract a distinct disease entity?
  • Although small cell carcinoma of the gastrointestinal (GI) tract is well-recognized, nonsmall cell type high-grade neuroendocrine carcinoma (HGNEC) of this site remains undefined.
  • In this study, we aimed at delineating the histologic and immunophenotypical spectrum of HGNECs of the GI tract with emphasis on histologic subtypes.
  • Guided primarily by the World Health Organization/International Association for the Study of Lung Cancer criteria for pulmonary neuroendocrine tumors, we were able to classify 87 high-grade GI tract tumors that initially carried a diagnosis of either poorly differentiated carcinoma with or without any neuroendocrine characteristics, small cell carcinoma, or combined adenocarcinoma-neuroendocrine carcinoma into the following 4 categories.
  • The first was small cell carcinoma (n=23), which had features typical of pulmonary small cell carcinoma, although the cells tended to have a more round nuclear contour.
  • The second was large cell neuroendocrine carcinoma (n=31), which had a morphology similar to its pulmonary counterpart and showed positive immunoreactivity for either chromogranin (71%) or synaptophysin (94%) or both.
  • The third was mixed neuroendocrine carcinoma (n=11), which had intermediate histologic features (eg, cells with an increased nuclear/cytoplasmic ratio but with apparent nucleoli), and positive immunoreactivity for at least 1 neuroendocrine marker.
  • The fourth was poorly differentiated adenocarcinoma (n=17).
  • Further analysis showed that most HGNECs arising in the squamous lined parts (esophagus and anal canal) were small cell type (78%), whereas most involving the glandular mucosa were large cell (53%) or mixed (82%) type; associated adenocarcinomas were more frequent in large cell (61%) or mixed (36%) type than in small cell type (26%); and focal intracytoplasmic mucin was seen only in large cell or mixed type.
  • No significant survival difference was observed among the different histologic subtypes.
  • In conclusion, our study demonstrates the existence of both small cell and nonsmall cell types of HGNEC in the GI tract, and provides a detailed illustration of their morphologic spectrum.
  • There are differences in certain pathologic features between small cell and nonsmall cell types, whereas the differences between the subtypes of nonsmall cell category (large cell versus mixed) are less distinct.
  • Given the current uncertainty as to whether large cell neuroendocrine carcinoma is as chemosensitive as small cell carcinoma even in the lung, our data provide further evidence in favor of a dichotomous classification scheme (small cell vs. nonsmall cell) for HGNEC of the GI tract.
  • Separation of nonsmall cell type into large cell and mixed subtypes may not be necessary.

  • All 15 patients who underwent endometrial biopsies were proven to have endometrial carcinomas.
  • FIGO stages of endometrial carcinomas: IA 18 cases, IB 20 cases, IC 2 cases, IIA 3 cases; Stages of ovarian carcinomas: IA 19 cases, IB 4 cases, IC 7 cases, II 4 cases, III C 9 cases.
  • Twenty-four patients (55.8%) were in stage I both endometrial and ovarian carcinomas.
  • Thirty-eight of the 43 patients (88.4%) had a pathologically proven endometrial adenocarcinoma.
  • The predominant ovarian histology was endometrioid or mixed tumor with endometrioid components (30/43, 69.8%).
  • The 3- and 5-year survival rates of patients with both endometrioid and ovarian carcinomas were higher than that of those with non-endometrioid or mixed subtypes (93.8%, 82.0% vs. 79.7%, 69.0%).
  • The 3-year and 5-year survival rates of patients with early stage disease were better than those of the other patients (93.3%, 93.3% vs. 69.7%, 36.7%).
  • CONCLUSION: Synchronous primary cancers of the endometrium and ovary are different from either primary endometrial carcinoma or ovarian cancer, while it can usually be detected in early stage and with a good prognosis.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • OBJECTIVE: We aimed to investigate preoperative findings that are useful to distinguish intraductal papillary-mucinous neoplasm (IPMN) subtypes.
  • Invasive IPM carcinomas (IPMCs) were subdivided into early-stage nonaggressive (minimally invasive IPMC [MI-IPMC]) and more advanced and aggressive (invasive carcinoma originating in IPMC [IC-IPMC]) subtypes according to our recently proposed pathological criteria.
  • Multidetector-row computed tomography detected a component of invasive carcinoma in IC-IPMC with 86% sensitivity and 100% specificity.
  • In patients with IPMNs other than IC-IPMC, multivariate analysis demonstrated 3 significant predictive factors of malignancy: IPMN size (>40 mm), IPMN duct type (main pancreatic duct or mixed type), and the presence of a mural nodule or thick septum.
  • CONCLUSIONS: For preoperative evaluation of patients with IPMN, it is recommended to rule out IC-IPMC using multidetector-row computed tomography and then to categorize IPMN other than IC-IPMC according to malignant potential based on the diagnostic score.

  • [Title] Bronchioloalveolar carcinoma: a review.
  • Bronchioloalveolar carcinoma (BAC) is classified as a subset of lung adenocarcinoma but has a distinct clinical presentation, tumor biology, response to therapy, and prognosis compared with other subtypes of non-small-cell lung carcinoma (NSCLC).
  • Bronchioloalveolar carcinoma disproportionately affects women, never-smokers, and Asians and is characterized by growth along alveolar septae without evidence of stromal, vascular, or pleural invasion.
  • Although pure BAC accounts for approximately 4% of lung cancers, tumors with histologically mixed BAC and adenocarcinoma account for > 20% of all NSCLCs, and the incidence of BAC might be increasing.
  • Bronchioloalveolar carcinoma histology is most commonly found in small lesions identified incidentally on chest radiographs or computed tomography scans and might represent a precursor lesion to invasive adenocarcinoma.
  • As with other subsets of NSCLC, surgical resection is the only potentially curative treatment.
  • Patients with unresectable BAC are more likely to respond to the epidermal growth factor receptor tyrosine kinase inhibitors gefitinib and erlotinib than patients with other subtypes of NSCLC.
  • Stage for stage, patients with BAC have a higher rate of long-term survival but might have an increased rate of intrathoracic recurrence than patients with other subtypes of NSCLC.

  • [Title] Cathepsin K is selectively expressed in the stroma of lung adenocarcinoma but not in bronchioloalveolar carcinoma. A useful marker of invasive growth.
  • Lung bronchioalveolar carcinomas (BACs) are noninvasive tumors showing lepidic growth and excellent prognosis, whereas all the other variants of adenocarcinoma are invasive tumors with a worse prognosis.
  • The identification of minimal invasive foci in adenocarcinoma, therefore, is of prognostic relevance.
  • A series of 68 pulmonary tumors, including 40 acinar/papillary adenocarcinomas, 18 adenocarcinomas of the mixed subtype, and 10 BACs was tested by immunohistochemical analysis for cathepsin K expression, a proteinase involved in bone and extracellular matrix remodeling.
  • Our findings suggest pathogenetic implications of cathepsin K in the mechanisms of tumor invasiveness in lung carcinoma; in addition, cathepsin K immunodetection may be a valuable adjunct in the correct classification of pulmonary adenocarcinomas, especially in small sclerosing BACs and mixed adenocarcinoma subtypes with minimal infiltrative growth.

  • Adenocarcinomas (AC), squamous cell carcinomas (SCC) and adenosquamous carcinomas (ASC) are three histological subtypes of non-small-cell lung carcinomas (NSCLC).
  • ASC are morphologically mixed tumours that contain the two cell components AC and SCC.
  • Moreover, when classifying the three histological subtypes, using genes that discriminated AC and SCC, we observed that all ASC were classified as intermediate between the AC and SCC, some being closer to AC, others to SCC.
  • In conclusion, the ASC mixed lung tumours are more complex than simple mixes of AC and SCC components.

  • [Title] [A comparative evaluation of immunohistochemical markers for the differential diagnosis between malignant mesothelioma, non-small cell carcinoma involving the pleura, and benign reactive mesothelial cell proliferation].
  • It included broad-spectrum antibodies to cytokeratins (CKAE1/AE3, CKMNF116), vimentin, epithelial membrane antigen (EMA), mesothelial cells (HBME1, CK5/6, calretinin), adenocarcinoma cells (BerEp4, B72.3, CEA, TTF1), antibodies enabling the assessment of proliferation (Mib1) and cell-cycle regulating proteins (p53).
  • Positive staining for HBME1, CK5/6, and calretinin was seen only in the epithelioid and mixed subtypes of MM; the respective percentages of positive reactions were: HBME1, 90.2% and 73.3%; CK5/6 58.2% and 53.3%; calretinin, 72% and 75%.
  • Differentiation of MM from non-small cell carcinomas: Among the antibodies used in the study, anti-HBME1 had the highest sensitivity (76.7%) but lowest specificity (77.4%).
  • CONCLUSION: In diagnosing mesothelioma it is necessary to use a panel of immunohistochemical stains, which should contain antibodies to markers for adenocarcinoma and mesothelioma.

  • PURPOSE: The survival of patients with local-regional adenocarcinoma of the esophagus or esophagogastric junction (EGJ) treated with preoperative chemoradiation is much better in patients with pathologic complete response than those with residual tumor.
  • Some adenocarcinomas have mixed patterns, including signet-ring cell and mucinous histology, but the clinical significance of these subtypes is unknown.
  • EXPERIMENTAL DESIGN: We studied 412 consecutive patients with esophageal or EGJ adenocarcinoma treated with chemoradiation followed by esophagectomy (193 patients) or surgery alone (219 patients).
  • All 13 patients with acellular mucin pools and no residual carcinoma are still alive after an average follow-up time of 36 months.
  • CONCLUSIONS: Our study showed that patients with esophageal or EGJ adenocarcinoma who have signet-ring cell or mucinous histology benefited substantially from preoperative chemoradiation and esophagectomy.

  • [Title] Morphologic features of adenocarcinoma of the lung predictive of response to the epidermal growth factor receptor kinase inhibitors erlotinib and gefitinib.
  • Adenocarcinoma subtypes and morphologic features were defined in histologic and cytologic material.
  • RESULTS: Tumors from TKI responders tended to be better-differentiated adenocarcinomas with bronchioloalveolar carcinoma components.
  • Nonresponders showed more heterogeneous morphology, higher grade, and more subtypes, and were more likely to show solid growth.
  • In nonresponders, the only pure bronchioloalveolar carcinoma was mucinous, a subtype known to be negative for EGFR mutations.
  • Using World Health Organization criteria, all tumors in both groups other than pure bronchioloalveolar carcinomas would be classified as adenocarcinomas, mixed subtype, thereby obscuring some of these distinctions.

  • [Title] Misclassification of bronchioloalveolar carcinoma with cytologic diagnosis of lung cancer.
  • INTRODUCTION: Cytology is commonly used to diagnose non-small cell lung cancer (NSCLC) but is an inaccurate means of diagnosis of bronchioloalveolar carcinoma (BAC).
  • The aims of this study were to calculate the sensitivity and specificity of cytologic diagnosis of BAC and to estimate the misclassification of BAC as other subtypes of NSCLC.
  • METHODS: Preoperative fine-needle aspiration cytology diagnoses were compared to histology diagnoses in 222 patients, including 51 patients with pure or mixed BAC, who underwent lung resection for NSCLC at our institution since 1999.
  • RESULTS: The sensitivity and specificity of a cytologic diagnosis of BAC were 12% and 99%, respectively.
  • Based on cytologic diagnosis, 63% of BAC was misclassified as adenocarcinoma, and 18% was misclassified as undifferentiated NSCLC.
  • CONCLUSIONS: Diagnosis of NSCLC by cytology alone results in significant misclassification of BAC, most commonly as adenocarcinoma or undifferentiated NSCLC.

  • [Title] High-grade endometrial carcinoma: serous and grade 3 endometrioid carcinomas have different immunophenotypes and outcomes.
  • High-grade endometrial carcinomas are a heterogeneous group of tumors and include grade 3 endometrioid (EC-3), serous (SC), and clear cell carcinomas (CCC).
  • There are conflicting data about the prognosis of these subtypes of high-grade endometrial carcinoma; this may be a result of lack of reproducibility in classifying tumor cell type.
  • The purpose of this study was to examine differences in immunophenotype and outcome in a series of high-grade endometrial carcinomas, focusing on the comparison of EC-3 versus SC.
  • We selected 180 endometrial carcinomas of SC, EC, or CCC type.
  • No mixed carcinomas were included in the study.
  • We chose the following immunohistochemical markers, estrogen receptor (ER), insulin-like growth factor 2 mRNA-binding protein 3 (IMP3), p16, p53, progesterone receptor (PR), and phosphatase and tensin homolog (PTEN) as being significantly differentially expressed in endometrial carcinoma subtypes.
  • EC-3 carcinomas have a significantly better prognosis than SC carcinomas of the endometrium.

  • [Title] Clinical usefulness of the fluorodeoxyglucose (FDG)-PET maximal standardized uptake value (SUV) in combination with CT features for the differentiation of adenocarcinoma with a bronchioloalveolar carcinoma from other subtypes of non-small cell lung cancers.
  • PURPOSE: To evaluate the clinical usefulness of fluorodeoxyglucose (FDG)-PET maximal SUV in combination with CT features for differentiation of adenocarcinoma with bronchioloalveolar carcinoma (BAC) from other subtypes of non-small cell lung cancer (NSCLC).
  • We categorized NSCLC into adenocarcinoma with BAC feature and other subtypes.
  • Finally, there were 16 cases of adenocarcinoma with BAC and 109 cases of other NSCLC subtypes included in the study.
  • Several CT features of lung cancer were analyzed, including tumor size, presence of spiculation, margin (irregular or smooth), pattern of the mass (pure solid, pure ground glass opacity and mixed), associated pleural effusion and location (center, mid and periphery).
  • The diagnostic performances of CT alone, PET alone, and combination of two modalities to predict adenocarcinoma with BAC from other subtypes of NSCLC were calculated.
  • RESULTS: A nodule with a mixed pattern with partly solid and ground glass opacity was significantly more frequent CT feature of an adenocarcinoma with BAC (8/16, 50%) as compared with the other subtypes (2/109, 1.8%) (p<0.0001).
  • Maximal SUV of adenocarcinoma with BAC (mean=7.2) was significantly lower than that of other subtypes of NSCLC (mean=13.33) (p<0.0001).
  • Sensitivity, specificity, PPV, and NPV of CT for differentiating adenocarcinoma with BAC from other subtypes was 50% (8/16), 98.2% (107/109), 80% (8/10), and 93% (107/115), respectively.
  • CONCLUSION: Careful combined assessment of the FDG-PET maximal SUV and CT findings have the potential to differentiate an adenocarcinoma with BAC from other NSCLC subtypes, such as a pure BAC.

  • [Title] Papillary adenocarcinoma of the lung is a more advanced adenocarcinoma than bronchioloalveolar carcinoma that is composed of two distinct histological subtypes.
  • To clarify the clinicopathological nature of papillary adenocarcinoma (PA) of the lung, 20 cases of PA were collected consecutively from resected adenocarcinoma of the lung, studied immunohistochemically and, using molecular techniques, compared with bronchioloalveolar carcinoma (BAC).
  • Morphologically, PA was divided into two subtypes according to the presence of residual alveolar structures, detected by elastica van Gieson stain.
  • One of these subtypes was closely related to the morphology of BAC and might be diagnosed as adenocarcinoma with mixed subtypes.
  • The other PA subtype was composed of tall columnar cells and grew compressively, which was similar to type F adenocarcinoma previously reported by Noguchi et al.
  • Immunohistochemical studies using lung tissue-specific antigens, progression markers and tumor suppressor products found that PA seemed a more advanced adenocarcinoma than BAC, but no differences were observed among PA subtypes.
  • Molecular biological analysis using three microsatellite markers at chromosome 3p revealed more frequent loss of heterozygosity in PA than BAC, with no differences among PA subtypes.
  • These findings suggest that PA is a more advanced adenocarcinoma subtype than BAC.
  • Further investigations are needed to clarify true PA as clinicopathologically and biologically independent from other histological subtypes of adenocarcinoma of the lung.

  • [Title] [Correlation of early phase contrast enhancement of multi-detector row computed tomography to tumor stroma of nodular solid lung adenocarcinoma].
  • This study was to evaluate the correlations of early phase enhancement of MDCT to proportion and distribution of stroma in solid lung adenocarcinoma.
  • METHODS: A total of 31 patients with lung adenocarcinoma underwent routine contrast-enhanced MDCT.
  • Of the 31 nodules, 18 (58.1%) showed homogenous enhancement, 10 (32.3%) showed peripheral inhomogenous enhancement, 1 (3.2%) showed central inhomogenous enhancement, 1 (3.2%) showed asymmetrical inhomogenous enhancement, 1 (3.2%) showed no enhancement; 18 (58.1%) nodules showed mixed distribution of stroma, 11 (35.5%) showed peripheral distribution, 1 (3.2%) showed central distribution, 1 (3.2%) showed asymmetrical distribution.
  • CONCLUSIONS: Extent and pattern of CT enhancement of solid lung adenocarcinoma nodules reflect the proliferation and distribution of stroma, respectively.
  • It is helpful to comprehend some false negative on CT enhancement by adequately understanding of the pathologic features of different subtypes of lung adenocarcinoma.

  • [Title] Predictive advantage of a cell type classification for pulmonary adenocarcinoma coupled with data for p53, K-ras and EGFR alterations.
  • We analyzed relationships between histological subtypes of pulmonary adenocarcinomas and three gene alterations (p53, K-ras, and epidermal growth factor receptor gene), or thyroid transcription factor-1 (TTF-1) expression, and also studied prognoses by the subtypes, with or without combined multiple gene mutation status.
  • A total of 223 consecutively resected pulmonary adenocarcinomas were sub-classified using either the World Health Organization (WHO) or our five-cell type (FCT) classification system (hobnail, columnar/cuboidal, mixed, polygonal/oval, and goblet cell types).
  • The most striking result was: while almost 70% of adenocarcinomas were sub-classified as a mixed subtype by WHO, the FCT classified many of them as other cell subtypes.
  • The FCT closely reflected differences in etiological factors, cellular lineages, and frequencies of gene mutations; and whether the data from combined gene mutations were used or not, differences among the cell types in postoperative survivals appeared.
  • In contrast, subtypes of WHO did not show any association with the gene alteration or prognosis, and the FCT more suitably indicated sensitivity to gefitinib therapy than did WHO.
  • The FCT combined with multiple gene mutation status appears to be useful in indicating pathogenesis and predicting the biological nature of pulmonary adenocarcinomas, and it could facilitate development of new therapies for each subtype.

  • [Title] Mixed adenocarcinomas of the lung: place in new proposals in classification, mandatory for target therapy.
  • The current lung cancer classification (World Health Organization 2004) can efficiently distinguish clinically relevant major subtypes (small cell and non-small cell carcinomas), but its results are partly inadequate when facing prognostic and therapeutic decisions for non-small cell carcinomas, especially for the group of tumors classified as adenocarcinoma.
  • Lung adenocarcinoma comprises a heterogeneous group of tumors characterized by diverse morphologic features and molecular pathogenesis.
  • The category of mixed adenocarcinomas includes most adenocarcinomas (approximately 80%) and, according to World Health Organization criteria, is defined by the occurrence of a mixed array of different patterns (acinar, papillary, bronchioloalveolar, solid with mucin).
  • The histologic recognition of mixed adenocarcinoma is subjective and cannot consistently discriminate between responders and nonresponders to new targeted therapies (eg, tyrosine kinase inhibitors).
  • In this evolving scenario, pathologists face new challenging diagnostic roles that include not only the precise morphologic definition of carcinoma subtypes but also their molecular characterization.
  • OBJECTIVE: To use a comprehensive critical analysis reconciling the overwhelming variety of biologic, morphologic, molecular, and clinical data to define new classification schemes for lung adenocarcinoma.
  • CONCLUSIONS: A new classification approach should redefine lung adenocarcinoma heterogeneity reconciling classic morphology, immunophenotypic and molecular features of neoplastic cells, and also relevant information provided by stem cell biology.
  • This approach, which has been already successfully applied in World Health Organization classification of other tumors, could improve the recognition of new reproducible profiles for adenocarcinomas, more closely and reproducibly related to clinical features and response to specific therapies, limiting the use of "wastebasket" categories such as mixed adenocarcinoma.

  • [Title] Salivary gland-type tumors of the breast: a spectrum of benign and malignant tumors including "triple negative carcinomas" of low malignant potential.
  • In the breast, benign adenomyoepithelioma is recognized in addition to malignant one, whereas in the salivary gland a histologically similar tumor is designated as epithelial-myoepithelial carcinoma without a separate benign subgroup.
  • Mammary adenoid cystic carcinoma is a low-grade neoplasm compared with its salivary equivalent.
  • It is also important to appreciate that in contrast to "triple negative" conventional breast carcinomas with aggressive course, most salivary-type malignant breast neoplasms behave in a low-grade manner.
  • Well established examples of this group include pleomorphic adenoma, adenomyoepithelioma, and adenoid cystic carcinoma.
  • Key examples include mucoepidermoid carcinoma and acinic cell carcinoma.
  • The number of cases of salivary gland-type mammary neoplasms in the published data is constantly increasing but some of the rarest subtypes like polymorphous low-grade adenocarcinoma and oncocytic carcinoma are "struggling" to become clinically relevant entities in line with those occurring more frequently in salivary glands.

  • [Title] Bronchioloalveolar carcinoma and lung adenocarcinoma: the clinical importance and research relevance of the 2004 World Health Organization pathologic criteria.
  • INTRODUCTION: Advances in the pathology and computed tomography (CT) of lung adenocarcinoma and bronchioloalveolar carcinoma (BAC) have demonstrated important new prognostic features that have led to changes in classification and diagnostic criteria.
  • The group addressed the question of whether sufficient data exist to modify the 2004 World Health Organization (WHO) classification of adenocarcinoma and BAC to define a "minimally invasive" adenocarcinoma with BAC.
  • The problems of diffuse and/or multicentric BAC and adenocarcinoma were evaluated.
  • Most lung adenocarcinomas, including those with a BAC component, are invasive and consist of a mixture of histologic patterns.
  • Therefore, they are best classified as adenocarcinoma, mixed subtype.
  • In small biopsy specimens or cytology specimens, recognition of a BAC component is possible.
  • CONCLUSION: Advances in understanding of the pathology and CT features of BAC and adenocarcinoma have led to important changes in diagnostic criteria and classification of BAC and adenocarcinoma.
  • The 2004 WHO classification of adenocarcinoma is readily applicable to research studies, but attention needs to be placed on the relative proportion of the adenocarcinoma subtypes.
  • Other recently recognized prognostic features such as size of scar, size of invasive component, or pattern of invasion also seem to be important.
  • More work is needed to determine the most important prognostic pathologic features in lung adenocarcinoma.

  • OBJECTIVE: Further investigation on the incidence and clinicopathologic features of bronchioloalveolar carcinomas (BAC) including:.
  • (1) BAC of strictly defined, (2) adenocarcinoma with bronchioloalveolar features, (3) other different histologic subtypes of lung adenocarcinomas.
  • METHODS: Surgical specimens from 348 lung adenocarcinoma patients admitted in that hospital between 1998 - 2005 were included.
  • RESULTS: The resected lung adenocarcinomas consisted of different histologic subtypes.
  • The most frequent one was adenocarcinoma of mixed subtypes (78.2%, 272/348), followed by the acinar type (8.1%, 28/348), the papillary type (4.0%, 14/348), the BAC (3.7%, 13/348), the mucinous (colloid) type (3.4%, 12/348) and the solid types (2.3%, 8/348).
  • The fetal adenocarcinoma was the least component detected.
  • CONCLUSIONS: Since patients with strictly defined (simple) BAC, BWFI, and AWBF have their own distinct clinicopathologic features and prognosis respectively, they should be strictly distinguished from other types of pulmonary adenocarcinomas.

  • Current World Health Organization (WHO) classification of lung adenocarcinomas includes noninvasive bronchioloalveolar carcinoma (BAC) and several patterns of invasive adenocarcinoma.
  • The most common is a mixed subtype of adenocarcinoma.
  • This group is very heterogenous and includes a wide spectrum of tumors ranging from adenocarcinomas with a dominant BAC growth pattern (lepidic growth) to frankly invasive adenocarcinoma with no BAC component.
  • The change in WHO definition of BAC and introduction of mixed subtype of adenocarcinoma resulted in disconnect between surgical pathologists and clinicians regarding the use of terminology and criteria for diagnosis of BAC and mixed subtype of adenocarcinoma.
  • It is clear that pure BAC is an extremely rare tumor, whereas mixed subtypes of adenocarcinomas may have various clinical presentations and outcomes.
  • The mounting evidence suggests that a subset of mixed subtype of adenocarcinomas with areas of BAC and focal invasion probably represent more indolent tumors.
  • On the basis of the published data, there is a proposal to define a subcategory of "minimally invasive adenocarcinoma" of the lung.
  • Many morphologic factors seem to play a role in predicting the behavior of these tumors.

  • Bronchioloalveolar carcinoma (BAC) is a previously uncommon subset of adenocarcinoma with unique epidemiology, pathology, radiographic presentation, clinical features, and natural history compared with other non-small cell lung cancer (NSCLC) subtypes.
  • The initial radiographic presentation of BAC varies considerably, from single ground glass opacities (GGOs) or nodules of mixed ground glass and solid attenuation to diffuse consolidative or bilateral multinodular disease.
  • The rising incidence of BAC is also reflected in recent lung cancer screening studies employing helical computed tomography (CT), where the differential diagnosis of GGOs includes not only BAC and overt adenocarcinoma, but inflammatory disease, focal fibrosis, and atypical adenomatous hyperplasia.

  • In contrast to three other EOC cell lines (TOV81D, TOV112D and TOV21G) and primary cultures derived from normal ovarian surface epithelial cells (NOSE), sequence analysis of the cDNA revealed a deletion of G at position 1484 of the transcribed sequence which is located within the 3'UTR of H3F3B.
  • OV90 was derived from ascites fluid of an undifferentiated adenocarcinoma of ovarian origin.
  • The variant allele was identified in EOC samples of clear cell (1 of 20), mucinous (1 of 8), mixed cell (1 of 3) and undifferentiated (1 of 2) histopathological subtypes but none of 34 serous or 12 endometrioid subtype tumors.
  • The functional significance of the variant is unknown, however its presence in rare subtypes of ovarian epithelial tumors warrants further investigation.

  • Previously, such lesions have been variously designated as adenocarcinoid, goblet cell carcinoid (GCC), and mixed adenocarcinoma carcinoid.
  • In this study, we undertook a retrospective investigation of 63 such cases and classified them as typical GCC (group A) and adenocarcinoma ex GCC on the basis of the histologic features of the tumor at the primary site.
  • The adenocarcinoma ex GCC group was further divided into signet ring cell type (group B) and poorly differentiated adenocarcinoma type (group C).
  • The clinical characteristics and prognosis were compared within these groups and with conventional de novo appendiceal adenocarcinomas.
  • The overall disease-specific survival for all subtypes was 77%, with 46% of patients without evidence of disease and 31% alive with disease.
  • They display a spectrum of histologic features and possess the potential to transform to an adenocarcinoma phenotype of either signet ring cell or poorly differentiated adenocarcinoma types.
  • Careful evaluation of the morphologic features of GCCs and appropriate pathologic classification are crucial for clinical management and prediction of outcome.
  • Surgical management with right hemicolectomy is recommended after appendectomy for most cases, particularly those with an adenocarcinoma component (groups B and C).

  • [Title] FGFR2 mutations are rare across histologic subtypes of ovarian cancer.
  • Given the similarities in the histologic and molecular genetics of ovarian and endometrial cancers, we hypothesized that activating FGFR2 mutations may occur in a subset of endometrioid ovarian tumors, and possibly other histotypes.
  • METHODS: Six FGFR2 exons were sequenced in 120 primary ovarian tumors representing the major histologic subtypes.
  • No mutations were detected in clear cell, mucinous, or mixed histology tumors or in the ovarian cancer cell lines tested.
