A multicentre retrospective cohort study of ovarian germ cell tumours: Evidence for chemotherapy de-escalation and alignment of paediatric and adult practice.

Eur J Cancer 2019 Apr 4;113:19-27. Epub 2019 Apr 4.

Barts Health NHS Trust, West Smithfield, London, EC1A 7BE, UK; University College Hospital, 235 Euston Road London, NW1 2BU, UK; Centre for Molecular Oncology, Barts Cancer Institute, Queen Mary University of London, Charterhouse Square, London EC1M 6BQ, UK. Electronic address:

Background: Adult guidelines recommend BEP (bleomycin, etoposide, cisplatin) for all ovarian germ cell tumours, causing debilitating toxicities in young patients who will survive long term. Paediatricians successfully reduce toxicities by using lower bleomycin doses and substituting carboplatin for cisplatin, while testicular and paediatric immature teratomas (ITs) are safely managed with surgery alone.

Aim: The aim was to determine whether reduced-toxicity treatment could rationally be extended to patients older than 18 years. Read More

D Lim E Oliva

Semin Diagn Pathol 2019 Feb 1. Epub 2019 Feb 1.

Department of Pathology, Massachusetts General Hospital, Boston, MA, USA.

Approximately 5% of gynecological malignancies are associated with paraneoplastic hypercalcemia. Awareness of its association with certain tumor types allows for earlier disease detection and facilitates monitoring of treatment response and disease recurrence. We review the salient clinicopathological features, differential diagnosis and management issues in some of these gynecological tumors, namely: small cell carcinoma, hypercalcemic type; ovarian clear cell carcinoma, dysgerminoma and juvenile granulosa cell tumors.

Department of Radiology, Osaka University Graduate School of Medicine, 2-2, Yamadaoka, Suita, Osaka, 565-0871, Japan.

We report the imaging findings of three ovarian dysgerminomas that coexisted with other germ cell tumors or gonadoblastomas, focusing on the distribution of tumor nests and vascular architecture, which might provide information about the pathogenesis of dysgerminomas. In a 14-year-old female with dysgerminoma and coexisting gonadoblastomas, contrast-enhanced magnetic resonance imaging (MRI) demonstrated a solid mass in the right ovary, which presented as hyperintense lobules on diffusion-weighted imaging separated by fibrovascular septa. Some small nodules were found to exist separately from the lobules (multiplicity) and to include pathological remnants of gonadoblastoma. Read More

Is fertility sparing surgery a treatment option for premenopausal patients with dysgerminoma?

Bratisl Lek Listy 2016 ;117(12):738-740

Dysgerminoma is the most common ovarian germ cell type ovarian tumour. Primarily, it presents in young women at reproductive age and thus, the preservation of fertility is considered to be fundamental when it is possible for these patients. In comparison to the past the restriction of the extent of the surgical procedure as well as the introduction of innovative chemotherapeutic regimens improved significantly both, the prognosis and the clinical outcomes of this rare neoplasia.

PLoS One 2016 28;11(12):e0168484. Epub 2016 Dec 28.

Institute of Medical Genetics, Linyi People's Hospital, Shandong, China.

SRY-mutation-caused sex reversal is a rare disease and mostly associated with a de novo mutation since the patients with defective SRY is infertile. There are many reports about SRY-mutation associated 46, XY ovarian disorder of sex development (DSD), but few described their molecular mechanism. Here we report a de novo mutation 224G>T (R75M) in SRY associated with a phenotypic female, 46, XY karyotype and dysgerminoma. Read More

Familial forms of disorders of sex development may be common if infertility is considered a comorbidity.

BMC Pediatr 2016 11 29;16(1):195. Epub 2016 Nov 29.

Human Developmental Genetics, Institut Pasteur, Paris, France.

Background: Families with 46,XY Disorders of Sex Development (DSD) have been reported, but they are considered to be exceptionally rare, with the exception of the familial forms of disorders affecting androgen synthesis or action. The families of some patients with anorchia may include individuals with 46,XY gonadal dysgenesis. We therefore analysed a large series of patients with 46,XY DSD or anorchia for the occurrence in their family of one of these phenotypes and/or ovarian insufficiency and/or infertility and/or cryptorchidism.
