Role of staging surgery and adjuvant chemotherapy in adult patients with apparent stage I pure immature ovarian teratoma after fertility-sparing surgery.

Int J Gynecol Cancer 2020 May 15;30(5):664-669. Epub 2020 Mar 15.

Department of Obstetrics and Gynecology, Peking Union Medical College Hospital, Chinese Academy of Medical Science and Peking Union Medical College, Beijing, China

Ovarian germ cell tumour classification: views from the testis.

Histopathology 2020 Jan;76(1):25-36

Centre for Molecular Oncology, Barts Cancer Institute, Charterhouse Square, Queen Mary University of London, London, UK.

The classification of ovarian germ cell tumours has remained unchanged for many years, while there have been considerable changes in the testicular classification. In recent years there has been concern about the overtreatment of clinical stage 1 testicular germ cell tumours with increasing use of surveillance for low-risk disease. We outline here the current classification of germ cell tumours of the ovary with particular regard to treatment and outcome and highlight some areas which may cause confusion, particularly pertaining to immature teratomas and mixed germ cell tumours.

Int J Gynecol Cancer 2019 10 30;29(8):1298-1303. Epub 2019 Jul 30.

Department of Medicine and Surgery, University of Milan-Bicocca, Milano, Italy.

Introduction: F-fluoro-2-deoxyglucose positron emission tomography/computed tomography (F-FDG PET/CT) is a diagnostic tool widely used in oncology, but to date there are no established recommendations for its use in malignant ovarian germ cell tumors.

TdT expression in germ cell tumours: a possible immunohistochemical cross-reaction and diagnostic pitfall.

J Clin Pathol 2019 Aug 4;72(8):536-541. Epub 2019 May 4.

Department of Medicine and Surgery, University Milan Bicocca, Milan, Italy

Aims: Very recent papers proposed a possible role for the expression of terminal deoxynucleotidyl transferase (TdT) in the tumourigenesis of gonadal and extragonadal germ cell-derived tumours (GCTs). Our multicentric study evaluated the magnitude of the immunoreactivity for TdT in GCTs, encompassing seminoma, dysgerminoma, mature teratoma and mixed GCTs.

Methods And Results: The histological series was stained with both monoclonal and polyclonal antibodies, yielding a positivity of 80% of cases with well-defined nuclear reactivity. Read More

Eur J Cancer 2019 05 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 Jul 1;36(4):246-259. 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.

Prognostic significance of residual disease in advanced stage malignant ovarian germ cell tumors.

Int J Gynecol Cancer 2019 03 29;29(3):554-559. Epub 2019 Jan 29.

Department of Obstetrics and Gynecology, Weill Cornell Medicine, New York City, New York, USA.

Objective: To investigate the prognostic significance of complete gross resection following cytoreductive surgery for patients with advanced stage malignant ovarian germ cell tumors.

Methods: The National Cancer Data Base was accessed and patients diagnosed with an advanced stage (II-IV) malignant ovarian germ cell tumor who underwent primary cytoreductive surgery between 2011 and 2014 were selected for further analysis. For analysis purposes two groups were formed: patients with complete gross resection and those with macroscopic residual disease. Read More

'Size does matter': Prophylactic gonadectomy in a case of Swyer syndrome.

J Gynecol Obstet Hum Reprod 2019 Apr 25;48(4):283-286. Epub 2019 Jan 25.

Department of Cytology and Gynecological Pathology, Postgraduate Institute of Medical Education and Research, Chandigarh, India.

Swyer syndrome also known as pure or complete gonadal dysgenesis is a very rare disorder of sex development wherein the individuals are phenotypically females with 46, XY genotype and preserved mullerian structures. These individuals characteristically have dysgenetic streak gonads which carry an increased risk of malignant transformation. Prophylactic gonadectomy is highly recommended as soon as a clinical diagnosis is established to diminish the chances of tumor development. Read More

Are omentectomy and lymphadenectomy necessary in patients with apparently early-stage malignant ovarian germ cell tumors?

Int J Gynecol Cancer 2019 Jan 23. Epub 2019 Jan 23.

Department of Gynecologic Oncology, Sun Yat-sen University Cancer Center, State Key Laboratory of Oncology in South China, Collaborative Innovation Center for Cancer Medicine, Guangzhou, People's Republic of China

Objective: To evaluate the role of omentectomy and lymphadenectomy in the treatment of clinically apparent early-stage malignant ovarian germ cell tumors.

Methods: We retrospectively reviewed 245 patients with malignant ovarian germ cell tumors (yolk sac tumor, dysgerminoma, and immature teratoma) and with clinically early-stage disease, who were treated at Sun Yat-sen University Cancer Center between January 1, 1970 and December 31, 2017. The survival of patients who underwent either omentectomy or lymphadenectomy, or both (omentectomy/lymphadenectomy group) was compared with that of patients who did not undergo omentectomy or lymphadenectomy (non-omentectomy/lymphadenectomy group).

Department of Gynecology and Obstetrics, The Central Hospital of Wuhan, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, Hubei, China.

Background: Lymphadenectomy has been widely used in the treatment of malignant germ cell tumor of the ovary (OGCT), which is a kind of ovarian cancers occurred mostly in young women and adolescent girls. But the clinical decision mainly depends on the doctor's experience without a well-defined guideline. This population-based study aimed to evaluate the prognostic impact of lymphadenectomy in different stages of malignant germ cell tumors of the ovary. Read More

Objective: The coexistence of maternal malignancy and pregnancy has received increasing attention in Noninvasive prenatal testing (NIPT) studies. Malignancy in pregnant women potentially affects the copy number variation (CNV) profile in NIPT results. Only one case of hematologic cancer has been reported in a Hong-Kong pregnant women, and solid tumors have never been reported in pregnant Chinese women. Read More

Malignant Lymphoma of the Ovary: A Diagnostic Pitfall of Intraoperative Consultation.

Int J Gynecol Pathol 2018 Dec 3. Epub 2018 Dec 3.

Departments of Obstetrics and Gynecology (N.I., Y.F., T.S., A.K., T.O., F.K.) Pathology (Y. Ikura, Y. Iwai) Hematology (M.O.), Takatsuki General Hospital, Takatsuki, Japan.

Primary ovarian lymphomas are rare, but can potentially evoke diagnostic problems. We present a case of ovarian lymphoma, in which an ambiguous intraoperative pathologic report led to overtreatment (unnecessary surgery). A 73-yr-old woman with fatigue and low-grade fever was diagnosed as having a left ovarian tumor by imaging modalities. Read More

Br J Cancer 2018 10 5;119(7):864-872. Epub 2018 Oct 5.

Division of Epidemiology & Clinical Research, Department of Pediatrics, University of Minnesota, Minneapolis, MN, USA.

Background: Abnormal DNA methylation may be important in germ cell tumour (GCT) aetiology, as germ cells undergo complete epigenetic reprogramming during development. GCTs show differences in global and promoter methylation patterns by histologic subtype. We conducted an epigenome-wide study to identify methylation differences by GCT histology. Read More
