GATA-4 is a transcription factor expressed in Sertoli cells and less commonly in Leydig (interstitial) cells but not germ cells in adult human beings, cattle, pigs, and mice. We examined GATA-4 in 76 formalin-fixed, paraffin-embedded canine testicular tumors, including 21 Sertoli cell tumors (SCT), 28 Leydig (interstitial) cell tumors (LCT), 24 seminomas (GCT), and 3 mixed germ cell sex cord-stromal tumors (MGSCT). Our hypothesis was that immunohistochemistry for GATA-4 could discriminate between germ cell and sex cord-stromal tumors of the canine testis. SCTs (21/21) had strong diffuse nuclear and weak and inconsistent cytoplasmic staining. LCTs (27/28) also had strong diffuse nuclear staining and much weaker and granular cytoplasmic staining. GCTs were negative for this marker. Sex cord-stromal cells of MGSCT were also positive. These results indicate that GATA-4 is mainly expressed in sex cord-stromal tumors and not in germ cell tumors of the canine testis.

Background: Non-epithelial cancers of the ovary are uncommon. They include malignancies of germ cell origin, sex cord-stromal cell origin, metastatic carcinomas to the ovary, and a variety of extremely rare ovarian cancers, such as sarcomas and lipoid cell tumors. Nonepithelial malignancies account for about 10% of all ovarian cancers. Objective: To review the management of Non-epithelial ovarian cancer in the NCI Cairo university during a period of 5 years (2005 till 2010). Material and Methods: Retrospective study including 114 patients who were diagnosed and treated with Non-epithelial ovarian cancer (2005 to 2010). Data were collected from the biostatistics and cancer epidemiology department. Results: Out of 114 patients; 25(21.9%) were benign and 25 (21.9%) were borderline malignant; 55 (48.2%) were malignant and 9 (7.89%) of them were unpredicted biologic behavior; the median age of the study population was 49.7 years (range 14_83years). Panhysterectomy was done in 77(67.5%) of the patients; ovariectomy and debulking were done in 22(19.3%; salpingooophorectomy was done in 10(8.8%) 0f patients and cystectomy was done in 3(2.6%) and 2 cases underwent biopsy. Conclusion: Sex cord-stromal tumors and malignant germ cell tumors are the most common nonepithelial ovarian cancers. These tumors often, but not always, present with the sequelae of overproduction of either androgens or estrogens. It is important to diagnose these masses early, as overall prognosis is typically very good for early stage disease in all histological subtypes. Both sex cord-stromal tumors and malignant germ cell tumors of the ovary are treated with initial surgical resection. Fertility sparing surgery can be considered for both sex cord-stromal and malignant germ cell tumors of the ovary. Depending on the pathological diagnosis and disease stage, postoperative management consists of either expectant management or adjuvant chemotherapy. It is recommended that all patients with nonepithelial ovarian cancer be monitored for evidence of disease recurrence on a standardized schedule.

Abstract BACKGROUND: Ovarian tumors are one of the leading cancers in females with variable pathological types. This study describes the distribution, clinical and pathological details of various histopathological types of ovarian tumors in a tertiary care hospital in North India. MATERIALS AND METHODS: A retrospective data of 3 years were collected for ovarian tumors submitted to the pathology department of a tertiary care hospital. Data were classified according to the latest World Health Organization (WHO) Classification into epithelial tumors, germ cell tumors, sex cord–stromal tumors, and others. RESULTS: A total of 212 cases of ovarian tumors were studied, 186 were unilateral and 26 were bilateral. Resection specimen, part of specimen, and block review formed 80.2%, 15.1%, 4.7%, respectively. Epithelial tumors formed the majority in 71.7% of cases followed by germ cell tumors (22.2%), sex cord–stromal tumors (3.8%) and others (2.3%). Maximum number of cases in the respective groups occurred in the age groups 31–40, 21–30, 51–60, and 41–50 years, respectively. Overall, benign tumors were 63.7%, malignant tumors were 31.1%, and borderline were 5.2%. The most common histopathological type of benign and malignant tumor was benign serous cystadenoma (18.8%) and serous carcinoma (9.9%), respectively. CONCLUSION: In the present study, ovarian tumors were classified according to the WHO classification, epithelial and germ cell tumors were the major types of ovarian tumors. Benign epithelial tumor formed the majority with 46.2% cases. Serous cystadenoma and mature cystic teratoma were the predominant type of epithelial and germ cell tumors, respectively.

Abstract Background Germ cell tumors and sex cord stromal tumors are rare cancers of the ovary. They mainly affect young women and are associated with a high survival rate. The standard treatment mainly involves conservative surgery combined with chemotherapy [bleomycin, etoposide and cisplatin (BEP)] depending on the stage and the prognostic factors, as for testicular cancers. As reported in testicular cancer survivors, chemotherapy may induce sequelae impacting quality of life, which has not yet been evaluated in survivors of germ cell tumors and sex cord stromal tumors. The GINECO-VIVROVAIRE-Rare tumor study is a two-step investigation aiming to assess i) chronic fatigue and quality of life and ii) long-term side-effects of chemotherapy with a focus on cardiovascular and pulmonary disorders. Methods Using self-reported questionnaires, chronic fatigue and quality of life are compared between 134 ovarian cancer survivors (cancer-free ≥2 years after treatment) treated with surgery and chemotherapy and 2 control groups (67 ovarian cancer survivors treated with surgery alone and 67 age-matched healthy women). Medical data are collected from patient records. In the second step evaluating the long-term side-effects of chemotherapy, a subgroup of 90 patients treated with chemotherapy and 45 controls undergo the following work-up: cardiovascular evaluation (clinical examination, non-invasive cardiovascular tests to explore heart disease, blood tests), pulmonary function testing, audiogram, metabolic and hormonal blood tests. Costs of sequelae will be also assessed. Patients are selected from the registry of the INCa French Network for Rare Malignant Ovarian Tumors, and healthy women by the ‘Seintinelles’ connected network (collaborative research platform). Discussion This study will provide important data on the potential long-term physical side-effects of chemotherapy in survivors of Germ Cell Tumors (GCT) and Sex Cord Stromal Tumors (SCST), especially cardiovascular and pulmonary disorders, and neurotoxicity. The identification of long-term side-effects can contribute to adjusting the treatment of ovarian GCT or SCST patients and to managing follow-up with adapted recommendations regarding practices and chemotherapy regimens, in order to reduce toxicity while maintaining efficacy. Based on the results, intervention strategies could be proposed to improve the management of these patients during their treatment and in the long term.

Aim: This study reports surgical treatment and its outcome for boys with a testicular tumor, in order to analyze the considerations of testis-sparing surgery (TSS) and investigate whether, in retrospect, treatment was according to a recently developed algorithm. Methods: We retrospectively reviewed boys with testicular tumors who underwent surgical treatment between January 2000 and June 2020 at the Wilhelmina’s Children’s Hospital and the Princess Máxima Center for Pediatric Oncology, The Netherlands. Medical records were searched for clinical characteristics and outcome. Results: We identified 31 boys (median age = 5.5 years) with a testicular tumor, 26 germ cell tumors (GCTs), four sex cord-stromal tumors, and one gonadoblastoma. Seventeen boys (median age = 1.5 years) had malignant and 14 (median age = 3.6 years) had benign tumors. Four boys with benign GCTs were treated with TSS, 25 with radical inguinal orchiectomy (RIO), and 2 with scrotal orchiectomy. No recurrence or testicular atrophy was reported. All boys with benign testicular tumors were treated as suggested by the algorithm, except for one boy treated with RIO. Conclusion: Retrospective analysis of surgical treatment of prepubertal boys with benign testicular tumors showed that TSS appears to be safe, and should be considered based on clinicoradiological data, in line with our algorithm.

Abstract Background.—The histogenesis of alveolar soft part sarcoma remains elusive. Myogenic origin is favored, although conflicting data on immunohistochemical demonstration of muscle-associated markers exist. Myogenin and MyoD1, transcription factors of the myogenic determination family, have crucial roles in commitment and differentiation of mesenchymal progenitor cells to myogenic lineage and in maintenance of skeletal muscle phenotype. Their immunohistochemical detection is specific in characterization of rhabdomyosarcoma. Methods.—Antibodies for myogenin, MyoD1, desmin, and muscle-specific actin were employed on a large series of cases (n = 19) of formalin-fixed, paraffin-embedded alveolar soft part sarcoma. Results.—Minimal scattered nuclear staining was seen with myogenin. All cases had pronounced, nonspecific granular cytoplasmic immunostaining with MyoD1; nuclei were negative. All tumors were negative for desmin and muscle-specific actin. Ultrastructural study in 10 cases failed to reveal features of skeletal muscle differentiation. Conclusions.—Cytoplasmic staining with MyoD1 in alveolar soft part sarcoma may correspond to cross-reactivity with an undetermined cytoplasmic antigen. The lack of immunostaining with myogenin, MyoD1, desmin, and muscle-specific actin provides evidence against a myogenic origin for alveolar soft part sarcoma.
