INTRODUCTION: While many childhood cancers are curable with therapy, adverse consequences in fertility exist. We sought to assess the number of female patients with pelvic tumors receiving radiation therapy, and the proportion that undergo measures for fertility preservation (FP). METHODS: A total of 53 female patients treated with pelvic tumors from 2000 to 2016 were retrospectively identified. RESULTS: 19 (34%) of these patients underwent pelvic radiation therapy (pXRT)...

Ovarian fibrosarcomas are extremely rare tumors with little genomic information available to date. In the present report we present the tumoral exome and transcriptome and the germinal exome of an ovarian fibrosarcoma from a 9-years old child. We found a paucity of mutations (0.77/Mb) and CNV alterations. Of these, the most relevant were a point mutation in the metal-binding site of the microRNA-processing DICER1 enzyme and a frame-shift alteration in the tumor suppressor gene NF1. We validated a germinal truncating mutation in DICER1, which was consistent with a DICER1 Syndrome diagnosis, providing the first example of an ovarian fibrosarcoma as the presenting neoplasia in this syndrome...

BACKGROUND: Posttransplant liver graft failure occurs most often in male recipients of livers from female donors. The respective role of donor sex itself and the size disparity in graft vessels/bile ducts according to donor sex are unclear. Thus, we aimed to evaluate the importance of donor sex with adjustment for anastomotic size disparity between female and male donor grafts. METHODS: A total of 309 male patients without hepatic tumors who underwent living donor liver transplantation were analyzed (109 female and 200 male donors)...

Pathogenic germline DICER1 variants cause a hereditary cancer predisposition syndrome with a variety of manifestations. In addition to conferring increased cancer risks for pleuropulmonary blastoma (PPB) and ovarian sex cord-stromal tumors, particularly Sertoli-Leydig cell tumor, individuals with pathogenic germline DICER1 variants may also develop lung cysts, cystic nephroma, renal sarcoma and Wilms tumor, nodular hyperplasia of the thyroid, nasal chondromesenchymal hamartoma, ciliary body medulloepithelioma, genitourinary embryonal rhabdomyosarcoma and brain tumors including pineoblastoma and pituitary blastoma...

Adrenarche is when a child's adrenal cortex starts to secrete adrenal androgen precursors. Dehydroepiandrosterone (DHEA) is the most abundant product of the adrenal cortex, and is a weak androgen agonist thought to be responsible for the clinical signs of pubarche by conversion to more potent androgens, testosterone, and dihydrotestosterone. DHEA's extra-adrenal sulfation product, dehydroepiandrosterone sulfate, is a stable marker for adrenal androgenic activity. Pubarche is the physical manifestation of androgenic hormone production, and includes the development of pubic and axillary hair, adult body odor, and acne...

BACKGROUND: Whereas among pediatric oncologists, ovarian yolk sac tumor (O-YST) is considered a chemosensitive tumor, it is often cited as an adverse prognostic factor in adult women with ovarian germ cell tumors. METHODS: The Malignant Germ Cell International Consortium data set included 6 pediatric clinical trials (United States, United Kingdom, and France) and 2 adult gynecology clinical trials (United States). Any patient with an O-YST that was International Federation of Gynecology and Obstetrics stage IC or higher and treated with a platinum-based chemotherapy was eligible...

Ovarian masses requiring surgical intervention are uncommon in the pediatric population. Our aim is to report results of a multicentric Tunisian study concerning the clinical practice and the management of pediatric ovarian masses and to identify the factors that are associated with ovarian preservation. Between January 2000 and December 2015, 98 pediatric patients (<14 years) were surgically treated for ovarian masses at the five pediatric surgery departments in Tunisia. Ninety-eight patients were included in this study...

Germ cell tumors which arise mainly in pediatric and adolescent age group, account for 30% of all ovarian tumors, but constitute only 5% of all malignant ovarian tumors. The presentation is usually insidious with the patient presenting with abdominal swelling and dull aching pain. We report a rare case of a malignant germ cell tumor in a 12-year-old girl who presented with acute abdomen due to spontaneous rupture of tumor resulting in hemoperitoneum. The patient was taken up for emergency laparotomy and left salpingo-opherectomy with omentectomy and drainage of hemoperitoneum was done...

BACKGROUND: Epidemiology and pathology of ovarian tumors in the pediatric population are very different of these encountered in women. Few attempts have been made to analyze the whole spectrum of ovarian pathology in children, and only some of them included series of more than 200 cases. We performed a retrospective analysis of clinical and diagnostic aspects of ovarian tumors and tumor-like lesions in girls in order to identify the characteristics associated with malignancy with an attempt to elaborate a clinical management algorithm...

REVIEW
Cécile Faure-Conter, Farzana Pashankar
The question of giving or not adjuvant chemotherapy in pure ovarian immature teratomas (ITs) remains unsolved to date and illustrates differences in management between pediatric and adults oncologists. Because of the rarity of these tumors, this question has never been addressed through randomized trials. Standard of care for adult women with ovarian ITs is postoperative platinum based chemotherapy for all patients except FIGO stage IA, grade 1 tumors, whereas pediatric series concluded that surgery alone is curative for completely resected ovarian ITs, regardless of grade...

Because of the efficacy of systemic therapies, neoplasias which occur in pediatric and adolescent patients and in young adults have high cure rates. This means that fulfilling their wish to have children has become a more pressing concern, particularly among young women with malignant tumors. Premature ovarian failure is also a not insignificant problem as it has a lasting detrimental effect on quality of life. Every oncology patient who may potentially wish to have children should be informed about their options for preserving fertility prior to starting treatment...

BACKGROUND: Neonatal tumors are different from tumors of the older children and knowledge gained from treating older children can not be extrapolated to neonates. Neonates have immature physiology and their haematopoietic and immune systems are not fully developed and the response to therapy is unpredictable. Hence it is imperative to study these tumors as separate entity. The aim of this study is to analyse this rare set of tumors in terms of their incidence, clinical features and management...

Ovarian immature teratoma is a germ cell tumor that comprises less than 1% of ovarian cancers and is treated with surgical debulking and chemotherapy depending on stage. Growing teratoma syndrome (GTS) is the phenomenon of the growth of mature teratoma elements with normal tumor markers during or following chemotherapy for treatment of a malignant germ cell tumor. These tumors are associated with significant morbidity and mortality due to invasive and compressive growth as well as potential for malignant transformation...
