A Prospective Study

Aims: To study the distribution of different types of ovarian tumors seen in adolescents and children and evaluate the commonest tumor during this period. Methods: A prospective study conducted at Dept of Ob/Gyn, Tribhuvan University Teaching Hospital form January 1999 - January 2008. Results: There were a total of 80 cases of ovarian tumors in childhood and adolescents. Most of the cases had presented to the outpatient department of Ob/Gyn (54%), Medicine (10%), Surgery (21%) and Emergency Unit (15%). Majority of the cases were between the ages of 15 to 19 and tumors in childhood age up to 14 represented 21% of the total ( < 10year being 4). The most frequently occurring tumor was Germ cell tumors accounting for 59 (73.7%) of the total. Out of which dermoid was the most frequently occurring in 45(76.2%). Nineteen (23.71 %) of the total tumor were malignant. All of them underwent laparatomy followed by enucleation (14); Unilateral ophoorectomy (28), unilateral salphingooophorectomy (36) and TAHBSO (2). Conclusion: This study shows the preponderance of germ cell tumor and high percentages of malignancies within germ cell tumor in young children and adolescents.

Background: Ovarian cancers are common among females. The ovarian tumors are classified according to its histogenesis. In the present study, we analyzed the germ cell ovarian tumors reported in our institute. Materials and Methods: This study was a hospital based retrospective study. All ovarian germ cell tumor reported from Jan 2001 to Feb 2013 were retrieved and analyzed. The specimens were routinely processed and the slides were stained with H&E and special stains wherever required. Results: A total of 340 cases of ovarian tumors were reported and 150 cases (44%) were of germ cell origin. We had 137 cases of benign and 13 cases of malignant germ cell tumors. Most common subtype was mature cystic teratoma comprising 125 cases. Among the malignant cases, the most common was immature teratoma (5 cases). Age range in our series was from 8 to 82 years (mean 28 years). The most common age group affected was 21-30 years. Most of the malignant cases (76.9%) were in less than 30 years. Among the malignant cases majority (84.6%) were more than 10 cm in size. None of the malignant germ cell tumors were bilateral. Conclusion: Among germ cell tumors of ovary, mature cystic teratoma is the most common tumor and malignant subtypes are uncommon. Malignant tumors tend to occur in younger age group.

Background: Germ cell tumors are rare and complex group of heterogenous neoplasms that comprise both benign and malignant histology. The testes and ovaries are the most common sites. This descriptive study focused on distribution of malignant germ cell tumors with more detail study of ovarian malignant germ cell tumors.Materials and Methods: All cases of malignant germ cell tumor reported from department of pathology of Tribhuvan University Teaching Hospital over five years from April 2007 to April 2012 were included in the study.Results: Thirty five cases (24 female and 11 male) were diagnosed as having malignant germ cell tumors. Most patients were below 30 years of age. Ovary was the most common site followed by testes. Malignant ovarian germ cell tumor comprised 54.3% of all malignant germ cell tumors. Age of these patients ranged from 6 years to 32 years. Most common histologic type was yolk sac tumor.Conclusion: Malignant germ cell tumors can be seen in any age group from new born to old age. However malignant ovarian germ cell tumors occur mainly in first three decades of life, are mostly unilateral and are of large size at the time of diagnosis due to rapid growth. However these tumors are often of low stage and managed with conservative surgery.Journal of Pathology of Nepal (2012) Vol. 2, 289-292DOI: http://dx.doi.org/10.3126/jpn.v2i4.6880

Abstract INTRODUCTION Germ cell tumors in the central nervous system (CNS) typically arise either at suprasellar and/or pineal region, and occasionally at basal ganglia. We report a case of diagnostically challenging, recurrent germ cell tumor presented with diffuse intraaxial abnormality in and across the lower brainstem, which was diagnosed by the elevated placental alkaline phosphatase (PLAP) level in cerebrospinal fluid (CSF). CASE DESCRIPTION: A 28-year-old man had been treated by chemoradiotherapy at the previous hospital for bifocal suprasellar and pineal lesions with the provisional diagnosis of germinoma without histological confirmation. Three years later, he presented with progressive weakness of bilateral extremities for weeks. Magnetic resonance imaging showed a diffuse, bilaterally symmetric high intensity lesion on T2-weighted image with slight contrast enhancement across the ventral side of the medulla oblongata to the upper cervical spinal cord. Serum and CSF hCG, hCG-β, and AFP were all negative. Since the image findings were atypical for recurrent germ cell tumor, some kind of myelitis was initially suspected. Therefore, steroid pulse therapy was administered. However, the patient’s symptom was still gradually progressing. Then, the CSF PLAP turned out to be positive, indicating the recurrence of germinoma. Accordingly, platinum-based chemotherapy was administered, and the imaging findings, patient’s symptoms, and CSF PLAP began to improve. The patient is to be treated with radiotherapy following chemotherapy. CONCLUSION We report a rare case of CNS germ cell tumor that presented with diffuse intraaxial lesion in the lower brainstem in which examination of CSF PLAP was extremely useful.

Germ cell tumors represent only 20% to 25% of all benign and malignant ovarian neoplasms. Mixed germ cell tumors are a rare variety of non–dysgerminomatous germ cell tumors. They contain two or more elements; the most frequent combination being a dysgerminoma and an EST (Endodermal Sinus Tumor). We present a case of malignant mixed germ cell tumor comprising of yolk sac tumor, embryonal carcinoma and choriocarcinoma. A 13-year-old girl presented with a huge 25 x 18 cm mass in abdomen with raised values of CA-125, hCG, AFP (alpha-feto protein) and LDH (lactate dehydrogenase). She underwent laparotomy followed by unilateral salpingoopherectomy and infracolic omentectomy. Histopathology report revealed malignant mixed germ cell tumor comprising predominantly of EST with elements of embryonal carcinoma and non-gestational choriocarcinoma. Following surgery, she was started on adjuvant chemotherapy (Bleomycin, Etoposide and Cisplatin regimen). Mixed germ cell tumor (YST/EST, non-gestational choriocarcinoma and embryonal carcinoma) is a very rare tumor. Careful initial surgery with adequate staging biopsies followed by combination chemotherapy can greatly improve the prognosis of these patients

Introduction: Germ cell tumors are a group of tumors with different clinical presentation and histological and biological characteristics. Malignant germ cell tumors occur at all ages with a trend of bimodal distribution in infancy and adolescence. Objective: To evaluate the demographic characteristics, distribution of different types of germ cell tumor, treatment modalities and outcome of germ cell tumor in children in a tertiary care hospital of Bangladesh. Methods: In this retrospective study, data regarding age and sex distribution, location, types of tumors, management of germ cell tumor in children were retrieved from the medical records of pediatric oncology department in NICRH, Dhaka from 2008 to 2014. Results: Out of total 87 patients female were 50 and male 37. Most of the patients were up to 5 years of age. The gonadal germ cell tumors (80%) were more than extragonadal tumor (20%) in both male and female patients. The most common germ cell tumor was dysgerminoma (32%) followed by yolk sac tumor (29.8%) and teratoma (19.5%). Yolk Sac Tumor (51.4%) was the most common in male and dysgerminoma (56%) the commonest in female. Out of 87, seventy two (82.7%) received chemotherapy following surgery. Among those 72 patients who received chemotherapy 49 (68 %) patients completed their treatment. Until the last follow up 71.4% patients remained alive and tumor free. Conclusion: Germ cell tumors are the most variable tumor of all childhood malignancies that has difference in age, sex, location and histological subtypes. Gonadal tumors have better prognosis than extragonadal tumors in both the sex. DS (Child) H J 2019; 35(2) : 119-122

Abstract BACKGROUND Gain of short arm of chromosome 12 (12p) is commonly observed in testicular germ cell tumors (tGCTs). 12p gain is also frequently seen in intracranial GCTs (iGCTs). However, little is known about the clinical significance of 12p gain in iGCTs. MATERIALS AND METHODS We have collected over 200 fresh frozen tissue samples of iGCTs through the Intracranial Germ Cell Tumor Genome Analysis Consortium in Japan. Firstly, we analyzed DNA methylation status in 83 iGCTs, 3 seminomas and 6 normal control samples using Infinium Human Methylation 450K BeadChip array (Illumina, CA). Idat files were processed using R (Version 3.5.3) and minfi package (1.30.0) to generate copy number variations. Compared with average genome-wide copy number level, 12p gain was determined. Then, 58 iGCTs with clinicopathological information were analyzed for progression-free survival (PFS) and overall survival (OS). Those tumors that consist of only either germinoma and/or mature teratoma components were classified as Favorable Histology (FH) and all the others that contains malignant histological components were classified as Unfavorable Histology (UFH). RESULT 12p gain was observed in 100% (3/3) of seminoma, 13.6% (3/22) of germinoma, 16.7% (1/6) of mature teratoma, 25% (1/4) of immature teratoma, 55% (11/20) of mixed germ cell tumor, 100% (4/4) of yolk sac tumor, 100% (1/1) of embryonal carcinoma, and 100% (1/1) of choriocarcinoma. In total, 44.6% (37/83) of iGCT showed 12p gain. Regarding histological classification, the 12p gain rate in UFH (72%, 18/25) was significantly higher than that in FH (12.1%, 4/33, P&lt;0.01). Both PFS and OS were significantly worse in iGCTs with 12p gain (PFS: P=0.027, OS: P=0.0012). DISCUSSION 12p gain can be a molecular marker to predict prognosis and histological malignancy in iGCTs.

Extragonadal Germ Cell Tumors

Abstract Objective The most common presentation of Klinefelter syndrome (KS) is infertility and features of hypogonadism. Currently no consensus exists on the risk of malignancy in this syndrome. Several case reports show an incidence of extragonadal germ cells tumors (eGCT) of 1.5 per 1000 KS patients (OR 50 against healthy population). Malignant germ cell tumors are rare in children. They account for 3% of all children cancers. Young patients with a germ cell tumor are not routinely tested for Klinefelter syndrome. This can therefore result in underdiagnosing. Literature data suggest a correlation between eGCT and KS. To the best of our knowledge there is no precise description of the primary locations of germ cell tumors in KS patients. The purpose of this study is to evaluate age groups and primary locations of extragonadal germ cell tumors in Klinefelter patients. With this data we investigate whether it is necessary to perform a cytogenetic analysis for KS in every eGCT patient. Study design This study is based on case report publications in PubMed/Medline published until march 2020 that described “Klinefelter Syndrome (MeSH) AND/OR extragonadal germ cell tumors”. Publications were included when patients age, location and histology of the germ cell tumor was known. Two double blinded reviewers selected the studies.Results: 141 KS patients with eGCTs were identified. Mean age at presentation was 17.3 years (StDev + − 10.2). In contrast to the extragonadal germ cell tumors in adults, most eGCT in children were mediastinal or in the central nervous system (respectively 90/141; 64% and 23/141; 16% of all tumors). Distribution of histologic subtypes showed that the largest fraction represented a teratoma, mixed-type-non-seminomateus GCT and germinoma, respectively 34/141; 24%, 26/141; 18% and 20/141; 14% of all tumors. Conclusion These data suggest a correlation between primary extragonadal germ cell tumors and Klinefelter syndrome. There appears to be an indication for screening on KS in young patients with an eGCT in the mediastinum. A low threshold for radiologic examinations should be considered to discover eGCT. We emphasize the need for genetic analysis in all cases of a male with a mediastinal germ cell tumor for the underdiagnosed Klinefelter syndrome.

Significant Difference

To investigate the function of the hypothalamic-hypophyseal-gonadal axis in testicular germ cell tumors, we evaluated gonadotropin responses to gonadotropin-releasing hormone (GnRH) in 12 untreated patients with testicular cancer (5 seminomas and 7 non-seminomas). GnRH was given i.v. at a dose of 100 μg as a bolus, and venous blood samples were collected at 0, 20, 60, and 120 min. As controls, 14 healthy males were studied. Basal levels of testosterone, estradiol and prolactin were also detected in each patient. Hormonal serum concentrations were measured by the radioimmunoassay. Mean basal testosterone, estradiol and prolactin levels were not significantly different from those of controls. Patients had a lower FSH and LH peak after GnRH than controls, without, however, any significant difference. As regards histology, nonseminoma patients lacked an FSH response to GnRH and had statistically lower mean peak levels than controls. Moreover, non-seminoma patients had statistically lower mean peak values of LH after GnRH than controls. These data show that patients with testicular germ cell tumor, and more particularly those with non-seminomas, have an altered function of the hypothalamic-hypophyseal-gonadal axis, which is already present prior to therapy. Further studies, particularly in stage I patients treated only with orchiectomy, should be performed to confirm and better define the Physiopathologic significance of the altered hypothalamic-hypophyseal-gonadal axis in testicular cancer and to clarify the alteration of fertility, which is frequently present before treatment.
