  • He had undergone right high orchiectomy, chemotherapy with four courses of PEB regimen (cisplatin, etoposide, bleomycin) and retroperitoneal lymph node dissection the previous year.
  • The pathological findings showed mixed germ cell tumor (seminoma, yolk sac tumor, embryonal carcinoma) in the testis and mature teratoma in the draining lymph node.
  • Two courses of salvage chemotherapy using a VIP regimen (etoposide, ifosfamide, cisplatin) were performed after diagnosis of pulmonary metastases, but had no affect on tumor size.
  • The operation was followed by three courses of CYVADIC (cyclophosphamide, vincristine, adriamycin, dacarbazin) chemotherapy and oral cyclophosphamide, as a small residual tumor was suspected.

  • A small nodule was palpable in his left testis and ultrasonographic examination demonstrated that the nodule was low echoic.
  • Computed tomography showed a large mass in his left retroperitoneal space.
  • We thought the mass was a metastatic lesion from a testicular tumor.
  • Left orchiectomy was done and microscopic examination revealed no viable tumor cells.
  • Only fibrous tissue, small calcified areas, and hyaline bodies were found.
  • As tumor markers were normalized after 3 courses of chemotherapy with bleomycin, etoposide, and cisplatine, the retroperitoneal mass was removed with the left kidney.
  • It consisted of embryonal carcinoma, mature teratoma, and yolk sac tumor.
  • One course of adjuvant chemotherapy was done and the patient has since been free from recurrence.
  • We suppose that the tumor was a so-called 'burned-out' testicular tumor.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Prepubertal testicular germ cell tumors: 25-year experience in Taipei Veterans General Hospital.
  • BACKGROUND: Due to the rarity of testicular tumors in the prepubertal population, adequate information about their biological course is difficult to document well in a single institution.
  • The purpose of this study was to focus on prepubertal males in an attempt to evaluate clinical features and optimal management among various testicular germ cell tumors with long-term follow-up.
  • METHODS: We retrospectively reviewed the records of children younger than 12 years of age with primary testicular germ cell tumors between February 1981 and December 2005 at Taipei Veterans General Hospital.
  • Mean follow-up time was 139 months (range, 2-283 months).
  • All patients underwent radical orchiectomy as an initial treatment.
  • Twenty-nine (85.3%) patients had yolk sac tumors, and 5 (14.7%) had mature teratomas.
  • Of the 29 patients with yolk sac tumor, 26 (89.7%) were diagnosed as stage I, 1 (3.4%) as stage III, and 2 (7.0%) as stage IV.
  • Five (19.2%) of the 26 stage I yolk sac tumors progressed to metastasis after radical orchiectomy, and all of these 5 patients later received chemotherapy.
  • One patient initially with stage III yolk sac tumor and 2 patients with stage IV yolk sac tumor were also treated with chemotherapy.
  • Eventually, 1 patient with stage IV yolk sac tumor died due to tumor progression; the remaining 28 patients with yolk sac tumor all survived without tumor relapse after appropriate treatment.
  • In the 5 patients with teratomas, there was no tumor relapse after radical orchiectomy with a mean follow-up time of 139.1 months.
  • The 5-year survival rates for yolk sac tumor and teratomas were 96.5% and 100%, respectively.
  • CONCLUSION: The most common prepubertal malignant testicular tumor is yolk sac tumor, and the most common benign testicular tumor is teratoma.
  • Children with testicular germ cell tumors have excellent long-term survival rates after appropriate treatment.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] DNA topoisomerase I and II expression in drug resistant germ cell tumours.
  • A small number of testicular germ cell tumours are refractory to current chemotherapy regimens.
  • DNA topoisomerase I is the target for several new drugs and a potential candidate treatment for chemorefractory germ cell tumours.
  • DNA topoisomerase II alpha is the target for etoposide, which is currently used regularly in germ cell tumour treatment.
  • The expression of DNA topoisomerase I and II alpha were therefore assessed immunohistochemically in a range of testicular tumours, especially those with persistent malignant elements on retroperitoneal lymph node dissection.
  • Pre-chemotherapy orchidectomy specimens were matched with post-chemotherapy retroperitoneal lymph node dissections to examine changes in expression.
  • There was considerable variation in the expression of topoisomerase I in different tumour types.
  • Both yolk sac tumours and teratoma, mature showed universal expression of topoisomerase I, while 38% of seminomas and 30% of embryonal carcinomas were positive.
  • There was a negative correlation between topoisomerase I and II alpha expression (P=0.004) and downregulation of topoisomerase II alpha after chemotherapy (P=0.02).
  • Topoisomerase I expression appears to increase in those cases with residual teratoma, mature, but is largely unchanged in those cases remaining as embryonal carcinoma.
  • These results suggest that topoisomerase I inhibitors may be useful in chemorefractory germ cell tumours, especially yolk sac tumours and where there are unresectable residual teratoma, mature deposits.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Resection of retroperitoneal residual tumor after chemotherapy for testicular cancer indication and surgical techniques.
  • The standard therapeutic approach to patients with advanced germ cell tumors is a combination of systemic chemotherapy with surgical removal of the residual disease.
  • The indication of residual tumor resection (RTR) has changed during the last 10 years.
  • Surgery is not longer recommended after chemotherapy of pure seminoma and surveillance of the residual tumor is the favored option.
  • In nonseminomatous tumors, surgery after chemotherapy is recommended in most of the cases since large studies have shown that a considerable proportion of patients with complete radiological remission after chemotherapy harbor vital carcinoma or teratoma.
  • Prediction models of necrosis after chemotherapy in order to avoid RTR are not generally accepted since the accuracy of most models is too low.
  • RTR is indicated in patients with elevated markers after two different chemotherapy regimens (including salvage chemotherapy) either to resect teratoma or cystic residual disease or to remove chemorefractory disease.
  • In patients with marker normalisation after chemotherapy and necrotic tissue in frozen section histology, the surgical field may be reduced to the left- or right-sided template, respectively.
  • However, especially in patients with teratoma, yolk sac or non germ cell tumors after chemotherapy, the surgical removal of the residual tumor should follow the formal ipsilateral template in order to avoid late relapse of chemorefractory disease.

  • [Title] [Clinicopathologic and prognostic study of pediatric immature teratoma].
  • OBJECTIVE: To study the clinicopathologic features and biologic behavior of pediatric immature teratoma.
  • METHODS: The clinical data, pathologic features, immunohistochemical findings (for cyclin D1, P27 and Ki-67) and follow-up information of 39 cases of pediatric immature teratoma were analyzed.
  • RESULTS: Amongst the 39 cases studied, 12 arose in the sacrococcygeal region, 12 in testis, 5 in retroperitoneum, 4 in ovary, 4 in abdomen and 2 in mediastinum.
  • Seven of the cases contained foci of yolk sac tumor.
  • Immature neuroepithelial features used in histologic grading included the presence of primitive neural tubules, immature rosettes, undifferentiated neuroblastoma cells and primitive neuroectodermal structures.
  • Three of them, including 2 cases with histologic grade 3 (with or without yolk sac tumor component), recurred after operation.
  • On the other hand, p27 overexpression shows little correlation with tumor grade.
  • The prognosis of immature teratoma in children is different from that in adults.
  • Sacrococcygeal immature teratoma occurring in patients younger than 1 year old and with low histologic grade do not require postoperative chemotherapy if the tumor is completely excised.
  • Similarly, for testicular immature teratoma occurring in patients below 1 year of age, regardless of tumor grading, need no adjunctive therapy.
  • On the other hand, ovarian immature teratoma with high histologic grade requires postoperative chemotherapy, regardless of age of the patients.
  • The presence of microscopic foci of yolk sac tumor is a useful predictor of recurrence in pediatric immature teratoma.

  • [Title] The malignant potential of teratomas in infancy and childhood: the MAKEI experiences in non-testicular teratoma and implications for a new protocol.
  • Since 1982, mature and immature teratomas have been recruited into the MAHO and MAKEI protocols of the German Society for Pediatric Oncology and Hematology (GPOH) for testicular and non-testicular germ cell tumors in order to study the epidemiology and clinical behaviour of teratomas.
  • Patients were registered in the epidemiologic German Childrens Cancer Registry and the GPOH Childrens Tumor Registry for pathological review.
  • Patients with immaturity grade 2 and 3 according to Gonzales-Crussi were eligible for adjuvant chemotherapy.
  • 1) EFS after complete tumor resection has been estimated to 0.96 +/- 0.01 in both observation periods.
  • 2) Incomplete tumor resection remains the main risk factor for relapse (EFS 0.55 +/- 0.09).
  • 4) In MAKEI 83/86/89 four newborns with teratoma died due to perioperative complications and nine children as a result of tumor progression, whereas in MAKEI 96 no newborn died, only one child died from tumor progression, and another child died during long time observation for another reason (meningitis).
  • 5) In accordance to the experience of the MAKEI 83/86/89 studies, no child of the MAKEI 96 study presented with yolk sac tumor at recurrence if adjuvant chemotherapy was administered during first-line treatment because of immaturity.
  • In contrast, more than half of the children with tumor recurrence after watch and wait strategy had yolk sac tumor in addition to teratoma.

  • [Title] Topoisomerase II alpha expression in testicular germ cell tumors.
  • OBJECTIVES: Inhibitors of topoisomerase II alpha (TopoIIalpha), an enzyme with a crucial role in DNA maintenance, are included in the chemotherapy protocols for testicular germ cell tumors (GCTs).
  • Despite the success of current chemotherapy regimens, a significant number of patients experience relapse.
  • We analyzed TopoIIalpha expression in primary and metastatic testicular GCTs because this enzyme is a target for some antineoplastic agents.
  • METHODS: Primary GCT specimens from 109 patients, including 57 seminomas and 52 mixed GCTs (41 embryonal carcinomas, 23 yolk sac tumors, 19 seminomas, 8 choriocarcinomas, 17 teratomas with immature elements, and 16 teratomas with mature elements), were obtained from our archives.
  • The metastatic lesions from 11 of the patients with mixed GCTs included seven teratomas with mature components, five embryonal carcinomas, one yolk sac tumor, one choriocarcinoma, and one teratoma with immature components.
  • RESULTS: Most embryonal carcinoma (100%), yolk sac tumor (95%), seminoma (88%), and choriocarcinoma (62%) components of the GCTs were TopoIIalpha immunoreactive.
  • None of the teratoma specimens with mature elements expressed TopoIIalpha.
  • CONCLUSIONS: The results of our study have shown that TopoIIalpha is expressed in most seminomas, embryonal carcinomas, yolk sac tumors, and choriocarcinomas, suggesting a possible mechanism of sensitivity of these components to TopoIIalpha inhibitors.
  • These findings imply that the variable chemoresponsiveness of testicular GCTs could have an underlying molecular basis.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Predicting teratoma in the retroperitoneum in men undergoing post-chemotherapy retroperitoneal lymph node dissection.
  • PURPOSE: The biological potential of teratoma remains unpredictable, therefore identifying its presence in the retroperitoneum remains important.
  • We evaluated patients undergoing post-chemotherapy retroperitoneal lymph node dissection for nonseminomatous germ cell tumors to determine predictors of teratomatous elements in the retroperitoneum.
  • MATERIALS AND METHODS: We identified 532 patients from 1989 to 2003 who underwent retroperitoneal lymph node dissection following chemotherapy for nonseminomatous germ cell tumors at our institution.
  • RESULTS: Of the 532 patients in our series 450 (85%) received only induction chemotherapy and 82 (15%) required salvage chemotherapy.
  • Retroperitoneal nodal pathology revealed teratomatous elements in 235 (44%) patients and only teratoma in 210 (40%) patients.
  • By multivariate analysis testicular yolk sac tumor (p = 0.046), teratoma in the orchiectomy specimen (p <0.005), relative change in nodal size before and after chemotherapy (p <0.005), and no requirement for salvage chemotherapy (p = 0.03) were independent predictors for the presence of teratoma in the retroperitoneum.
  • CONCLUSIONS: Teratoma remains a common histological finding in the retroperitoneal lymph nodes following chemotherapy.
  • We have identified several pre-retroperitoneal lymph node dissection variables that predict the finding of teratoma in the retroperitoneum for men treated with chemotherapy for metastatic nonseminomatous germ cell tumors.

  • [Title] A case of spermatic cord teratoma in low-stage testicular cancer managed by surveillance.
  • BACKGROUND: A 25-year-old male presented to his local urologist with new-onset right testicular pain and swelling detected on self examination.
  • A scrotal ultrasound scan showed a right testicular mass, suspicious for neoplasm.
  • The patient underwent right inguinal orchiectomy and was diagnosed with nonseminomatous germ cell tumor of the right testis, composed of yolk sac tumor, teratoma, and embryonal carcinoma with no evidence of metastatic disease.
  • He opted to remain under surveillance rather than undergo primary chemotherapy or retroperitoneal lymph node dissection for his clinical stage I disease.
  • Serologic relapse at 4 months after orchiectomy was successfully treated with bleomycin, etoposide and cisplatin (BEP) chemotherapy.
  • Pathology of the testicular mass was reviewed.
  • DIAGNOSIS: A 1.7 cm nodule anterior to the right psoas muscle suspicious for metastatic disease that was seen on CT 16 months after orchiectomy was pathologically confirmed as recurrent mature teratoma in the spermatic cord.
  • Additionally, one of eleven interaortocaval lymph nodes showed evidence of teratoma.
  • The patient has since remained disease-free, with normal levels of serum tumor markers and no evidence of metastasis on chest X-ray and abdominal CT.

  • [Title] Recent developments in testicular germ cell tumor research.
  • Testicular germ cell tumors of adolescents and adults (TGCTs; the so-called type II variant) are the most frequent malignancies found in Caucasian males between 20 and 40 years of age.
  • TGCTs are divided into seminomas and nonseminomas, the latter consisting of the subgroups embryonal carcinoma, yolk-sac tumor, teratoma, and choriocarcinoma.
  • The developmental capacity of their cell of origin, the primordial germ cells/gonocyte, is demonstrated by the different tumor histologies of the invasive TGCTs.
  • Somatic differentiation is seen in the teratomas (all lineages), whereas yolk-sac tumors and choriocarcinoma represent extra-embryonal differentiation.
  • Seminomas are highly sensitive to irradiation and (DNA damaging) chemotherapy, whereas most nonseminomatous elements are less susceptible to radiation, although still sensitive to chemotherapy, with the exception of teratoma.

COS Scholar Universe. author profiles.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] The pathology of late recurrence of testicular germ cell tumors.
  • A total of 91 men had histologically documented late recurrences of testicular germ cell tumors characterized by a complete response to treatment with a subsequent disease-free interval of at least 2 years and no evidence of a second primary lesion.
  • Ninety percent of the patients for whom information was available received chemotherapy shortly after their initial diagnosis of testicular germ cell tumors; most of the other patients were known to have stage I disease initially.
  • Overall, 60% of patients had teratoma in their late recurrences, including 20 patients (22%) in whom teratoma was the only element.
  • Thus, teratoma was the most common type of neoplasm in late recurrences.
  • Excluding teratoma coexisting with other types of neoplasms, yolk sac tumor was the most frequent type of tumor in patients with late recurrence.
  • It occurred in 47% of patients, either alone or with teratoma, another nonteratomatous germ cell tumor type, or a "nongerm cell malignant tumor."
  • Unusual types of yolk sac tumor, including glandular, parietal, clear cell, and pleomorphic patterns, were seen frequently in late recurrences and often raised differential diagnostic problems with "nongerm cell" carcinomas.
  • A smaller number of late recurrences consisted of other types of neoplasms.
  • Twenty percent of patients with late recurrence had a nonteratomatous germ cell tumor other than yolk sac tumor, either alone, with yolk sac tumor, or with a "nongerm cell malignant tumor."
  • Most of these nonteratomatous germ cell tumors other than yolk sac tumor were embryonal carcinoma, although rarely seminoma and choriocarcinoma were encountered.
  • "Nongerm cell malignant tumors," including both sarcomas and carcinomas of various types, occurred in 23% of late-recurrence patients, either alone or with a nonteratomatous germ cell tumor.
  • Patients whose late recurrences consisted of teratoma only had the most favorable outcomes, with 79% having no evidence of disease at last follow-up.
  • Patients whose late recurrences consisted of pure "nongerm cell malignant tumor" or pure germ cell tumor (yolk sac tumor or other types) had a much worse prognosis: Only 36% to 37% were alive with no evidence of disease.
  • Patients with two different types of nonteratomatous malignancies in their late recurrences had a dismal clinical course: Only 17% with both yolk sac tumor and other nonteratomatous germ cell tumor had no evidence of disease, whereas no patient with both nonteratomatous germ cell tumor and "nongerm cell malignant tumor" was disease free.
  • Late recurrences consisting of teratoma alone often have a favorable outcome, but the prognosis in all other patients is poor.
  • Furthermore, late recurrence is not likely to respond to chemotherapy and is best treated by surgical excision when possible.

  • Children with stage I yolk sac tumors should be monitored closely with periodic AFP tumor marker evaluation and imaging according to the primary dissemination (e.g., ultrasound, chest x-ray, and computed tomography).
  • Patients with recurrent or metastatic yolk sac tumors should be treated with platinum-based chemotherapy and appropriate follow-up.
  • Retroperitoneal lymph node dissection is not recommended except for patients with residual retroperitoneal masses following chemotherapy.
  • Aggressive treatment is warranted for metastatic Sertoli cell and metastatic undifferentiated stromal tumors.

  • [Title] Epidemiological and clinical behavior of prepubertal testicular tumors in Korea.
  • PURPOSE: To our knowledge there is no multi-institutional report on prepubertal testicular tumors in Korea to date.
  • MATERIALS AND METHODS: The prepubertal testicular tumor registry form was mailed to all 87 hospitals registered in the Korean Urology Association.
  • Serum alpha-fetoprotein and beta-human chorionic gonadotropin increased in as many as 62.9% and 2.7% of patients, including 94.7% and 2.2% in those with yolk sac tumor and 30.4% and 2.7% in those with teratoma, respectively.
  • Germ cell tumors were the most common (89.4% of cases), mainly with yolk sac tumor (47.8%) or teratoma (39.7%).
  • Management after surgery included surveillance in 71.8% of cases, chemotherapy in 9.1%, combination therapy in 1.4% and other in 17.7%.
  • Of the total patients 10.5% (5.9% of stage I yolk sac tumors) had progression to metastasis.
  • The final results of treatment were complete remission (64.6% of cases), incomplete remission (2.9%), no response or disease progression (1.4%) and unknown (31.1%).
  • CONCLUSIONS: Demographic data on pediatric testicular tumors in Korea will lead to a better understanding of these rare tumors and to optimal therapy in these children.

  • [Title] The United Kingdom Children's Cancer Study Group's second germ cell tumor study: carboplatin, etoposide, and bleomycin are effective treatment for children with malignant extracranial germ cell tumors, with acceptable toxicity.
  • Stage I testicular and some ovarian GCTs were resected and monitored with alpha-fetoprotein (AFP) ("watch-and-wait" approach).
  • Chemotherapy toxicities were assessed using World Health Organization or Brock grading.
  • Eight were excluded because either there was no histologic diagnosis (n = 3) or chemotherapy was given off-study (n = 5).
  • The remaining 184 patients had germinoma (n = 20), malignant teratoma (n = 55), embryonal carcinoma (n = 1), yolk sac tumor (n = 107), or choriocarcinoma (n = 1).
  • The median follow-up after JEB treatment was 53 months (range, 0 to 109 months); the median number of courses was five (range, three to eight).
  • One child died of a thoracic tumor and bronchopulmonary dysplasia, and another died of acute myeloid leukemia.
  • CONCLUSION: Conservative surgery, a watch-and-wait approach after complete excision, and JEB for those requiring chemotherapy produced high cure rates and few serious complications.

  • [Title] Testicular germ cell tumors in children: management and outcome in a series of 20 patients.
  • Testicular germ cell tumors occurring during childhood are extremely rare.
  • This study reports the clinical presentation, pathological diagnosis, treatment methods and outcome in a series of 20 boys, aged between 3.5 months and 16 years (median: 1.5 years; 19 were prepubertal), who were treated between 1963 and 2003.
  • Histologically, mature teratoma was present in seven, immature teratoma in four and yolk sac tumor in nine.
  • Of the 11 teratomas, 10 were treated by orchiectomy and one by testis-sparing tumor excision only.
  • The nine patients with yolk sac tumor were managed by orchiectomy, in two plus retroperitoneal lymphadenectomy, and in eight plus chemotherapy.
  • One patient is in remission for 10 months, seven are alive with no evidence of disease for 5.5-23 years, and one patient died from a T-cell acute lymphoblastic leukemia, 2 years after the end of treatment of the testicular tumor.
  • A gradual switch towards less invasive treatment has been observed over the years.
  • This study confirms the excellent cure rates obtained in children with testicular germ cell tumor, provided diagnosis is prompt and treatment accurate.

  • [Title] Surgery in infants and children with testicular and paratesticular tumours: a single centre experience over a 25-year-period.
  • Testicular and even more paratesticular tumours in children are rare.
  • The aim of the study is to characterise the spectrum of these lesions with focus on the feasibility and effectiveness of testis sparing surgery.
  • The spectrum of testicular tumours comprised 13 germ cell tumours (6 yolk sac tumours, 6 teratomas, 1 embryonal carcinoma) and 4 sex cord stromal tumours (2 Leydig's cell, Sertoli's cell, granulosa cell).
  • Further on, we observed 3 boys with paratesticular rhabdomyosarcoma (RMS), and three with testicular and paratesticular metastases (Wilms' tumour, neuroblastoma, leukaemia).
  • Serum alpha1-fetoprotein (AFP) was clearly elevated in 5 of 6 yolk sac tumours but remained within normal limits concerning the other entities.
  • Dependent on tumour histology, stage and the recommended treatment schedule postoperative chemotherapy was added.
  • Testis sparing surgery was performed in 3 boys with primary testicular tumours (2 Leydig's cell, mature cystic teratoma).
  • During a median follow up of 5 years all patients with primary testicular tumours survived event free.
  • Meta-analysis of the recent literature revealed that testis sparing surgery is feasible and save in prepubertal boys after exclusion of a malignant tumour.
  • If a testis sparing approach is planned, the following criteria are essential: 1.
  • 3. The presence of sufficient healthy testicular parenchyma.
  • However, the high rate of malignant or potentially malignant tumours suggests that high inguinal orchidectomy should remain the surgical standard of therapy.

  • [Title] Metastatic germ cell tumor of the lung masquerading as primary rhabdomyosarcoma.
  • Two years after testicular resection was carried out in a 40-year-old man that revealed mixed germ cell tumor of more than one histological type (seminoma, embryonal cell carcinoma, and yolk sac tumor), he presented with an asymptomatic pulmonary nodule in his left lower lobe.
  • Video-assisted thoracoscopic partial resection of the tumor revealed a 24 x 20 mm teratoma with somatic-type malignancy in which pleomorphic rhabdomyosarcoma was a major element.
  • One year later, asymptomatic tumor recurrence occurred at both edges of the stapler line as 22 x 20 mm and 10 x 5 mm nodules composed only of pleomorphic rhabdomyosarcoma.
  • Throughout the course there was no abdominal lymph node swelling detected by computed tomography (CT) and tumor markers were normal.
  • Adjuvant chemotherapy was started after the tumor recurrence.
  • Currently, the patient is still undergoing chemotherapy 5 months after the tumor recurrence.
  • In conclusion, despite the fact that primary pulmonary rhabdromyosarcoma is a rare neoplasm, metastatic pulmonary germ cell tumor with somatic-type malignancy showing predominantly rhabdomyosarcomatous differentiation should be considered in the differential diagnosis of such lesions of the lung.

  • [Title] Clinical behavior and a contemporary management algorithm for prepubertal testis tumors: a summary of the Prepubertal Testis Tumor Registry.
  • PURPOSE: The Prepubertal Testis Tumor Registry was established by the Urologic Section of the American Academy of Pediatrics in 1980 to record data on a large number of prepubertal testis tumors regarding presentation, treatment and outcome to define appropriate management better.
  • MATERIALS AND METHODS: Relevant data in the prepubertal testis tumor registry were tabulated and analyzed.
  • RESULTS: There were 395 prepubertal patients who had a primary testis tumor.
  • Of the patients with yolk sac tumor 80% presented with stage 1 disease and overall survival was excellent.
  • There were no metastases or deaths among the patients with teratoma.
  • Of all patients with stromal tumors metastases developed in only 1.
  • CONCLUSIONS: We recommend initial excisional biopsy for all amenable prepubertal testis tumors, except those with an alpha-fetoprotein level that is clearly increased for patient age.
  • Patients with stage I yolk sac tumor should be monitored closely, and those with recurrent or metastatic yolk sac tumor should be treated with chemotherapy.
  • Retroperitoneal lymph node dissection is reserved for patients with recurrent retroperitoneal masses following chemotherapy.
  • Aggressive treatment of metastatic Sertoli cell or undifferentiated stromal tumors is warranted.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] [WHO classification of testicular tumors].
  • Twenty years after the first edition (1977), the WHO has presented the updated version of the "Histological typing of testis tumours".
  • Such atypical cells appear in the tubules adjacent to the germ cell tumors, in some few cases (6%) also in the contra lateral healthy gonad and rarely in infertile men (1%).
  • The precursor lesion can progress to franc germ cell tumor starting probably with seminoma, which still maintain the capability of differentiation (pluripotente cells) in all other types of non-seminomatous germ cell tumors.
  • Unfortunately, however, the old term "teratoma with malignant transformation" was changed to "teratoma with malignant areas" in the 1998 classification.
  • This is a harmless name for an extremely dangerous tumor in which one tissue overgrows the other and gives rise to somatic type sarcomas or carcinomas.
  • Such tumors do not respond like germ cell tumors to the usual chemotherapy.
  • Treatment should be tailored according to that used in standard management of the respective sarcoma or carcinoma.
  • In the comments it is mentioned that the testis carcinoid could be a part of teratoma, but the diagnosis is listed in the group of "miscellaneous" tumors together with tumors of ovarian epithelial type.
  • This is a very questionable decision because the normal testis does not contain neuroendocrine cells from which carcinoids would have to be able to develop.
  • This morphologically peculiar tumor can be part of the Swiss syndrome also called Carney's complex.
  • The patients have cardiac myxomas, spotty skin pigmentation, hormone active nodular hyperplasia of the adrenals and soft tissue myxomas.
  • For the therapy of germ cell tumor an assessment of risk factors found by the pathologists is extremely important.
  • The most important independent predictors of relapse are tumor invasion of blood or lymph-vessels, absence of yolk sac elements and the presence of an embryonal carcinoma component.
  • In the absence of such predictors a surveillance policy allows some patients to forgo chemotherapy.

  • [Title] Clinical stage I nonseminomatous germ cell tumors of the testis in childhood and adolescence: an analysis of 31 cases.
  • A 20-year single-institution experience of clinical stage I nonseminomatous germ cell tumors of the testis (NSGCTT) in childhood and adolescents was reviewed in relation to clinical characteristics, treatment modalities, and survival.
  • Yolk sac tumors and/or teratomas occurred in the children, whereas mixed histologies, including embryonal carcinoma, were predominant in the adolescents.
  • After orchiectomy, the children were assigned to surveillance and the adolescents to active treatment: 16 underwent retroperitoneal lymph node dissection (RPLND) and 1 had adjuvant cisplatin-based chemotherapy because of a high-risk histology.
  • Three of the 14 children (21.4%) relapsed 3, 7, and 8 months after orchiectomy: all 3 had yolk sac tumors and presented with increased alpha-fetoprotein levels.
  • All three children were treated with cisplatin-based chemotherapy with or without surgery.
  • All were treated with cisplatin-based chemotherapy with or without surgery.
  • In particular, almost all the childhood cases had the same yolk sac tumor histology, the children tended to have localized disease, and an increased alpha-fetoprotein level had a very high predictive value, suggesting that follow-up should include AFP measurements.
  • A conservative approach is the best option in children, while adolescent NSGCTT behaves like the adult disease and management must include similar treatment strategies.

  • PURPOSE: We evaluated the prognostic significance of the histology of metastatic lymph nodes to predict postoperative relapse in pathological stage B1 nonseminomatous germ cell tumor (NSGCT).
  • MATERIALS AND METHODS: A retrospective review of the testicular cancer database was performed to identify all patients with clinical stage A NSGCT who underwent primary retroperitoneal lymph node dissection and were found to have pathological stage B1 disease.
  • No patient received adjuvant chemotherapy and minimal followup was 24 months.
  • Embryonal cell carcinoma was identified in 92 of 118 (77%) surgical specimens, which was significantly greater than the presence of teratoma (22%), seminoma (16%) and yolk sac (14.4%, p < or = 0.001) with no difference in 5-year DFS comparing the presence or absence of each histology.
  • Embryonal cell carcinoma was the most common single histology identified at surgery at 64 of 88 (73%), with the incidence of seminoma, teratoma and yolk sac being 12.5%, 9.0% and 5.5%, respectively (p < or = 0.001).

  • Testicular carcinoid tumors are rare with only limited studies.
  • We identified 29 primary testicular carcinoid cases from 7 academic institutions.
  • The most common presenting symptom was the sole finding of either a testicular mass or swelling seen in 15/24 cases with available information.
  • Nineteen were pure carcinoid tumors, 3 were associated with cystic teratoma, 2 with cysts lacking epithelial lining, 4 with epidermoid cyst, and 1 with dermoid cyst.
  • All 29 primary carcinoids lacked associated intratubular germ cell neoplasia, unclassified type.
  • Of the 28 cases found premortem, treatment included focal excision in 3 patients and radical orchiectomy in 25 patients.
  • Follow-up, available in 24 cases, ranged from 1 to 228 months (mean 52.7 mo); of the 20 patients with testicular typical carcinoid tumors found premortem, all were alive at last follow-up without recurrences or metastases.
  • Of the 4 patients with a primary atypical carcinoid tumor, 1 at the time of diagnosis had retroperitoneal and lung metastases who after chemotherapy underwent resection of the retroperitoneal tumor showing metastatic yolk sac tumor and embryonal carcinoma.
  • After resection, serum AFP levels remained elevated and the patient is scheduled for salvage chemotherapy and bone marrow transplant.
  • Most primary carcinoid tumors of the testis have a benign clinical course even if associated with epidermoid/dermoid cysts, or histologically mature teratoma.
