Nivolumab Versus Gemcitabine or Pegylated Liposomal Doxorubicin for Patients With Platinum-Resistant Ovarian Cancer: Open-Label, Randomized Trial in Japan (NINJA).

Purpose: This phase III, multicenter, randomized, open-label study investigated the efficacy and safety of nivolumab versus chemotherapy (gemcitabine [GEM] or pegylated liposomal doxorubicin [PLD]) in patients with platinum-resistant ovarian cancer.

Materials And Methods: Eligible patients had platinum-resistant epithelial ovarian cancer, received ≤ 1 regimen after diagnosis of resistance, and had an Eastern Cooperative Oncology Group performance score of ≤ 1. Patients were randomly assigned 1:1 to nivolumab (240 mg once every 2 weeks [as one cycle]) or chemotherapy (GEM 1000 mg/m for 30 minutes [once on days 1, 8, and 15] followed by a week's rest [as one cycle], or PLD 50 mg/m once every 4 weeks [as one cycle]).

The mesenchymal transition subtype more responsive to dose dense taxane chemotherapy combined with carboplatin than to conventional taxane and carboplatin chemotherapy in high grade serous ovarian carcinoma: A survey of Japanese Gynecologic Oncology Group study (JGOG3016A1).

Objective: Recently, we established new histopathological subtypes of high-grade serous ovarian cancer (HGSOC) that include the mesenchymal transition (MT) type, the immune reactive (IR) type, the solid and proliferative (SP) type and the papillo-glandular (PG) type. Furthermore, we identified that the mesenchymal transcriptome subtype might be sensitive to taxane. We investigated whether these different histopathological subtypes of HGSOC require individualized chemotherapy for optimal treatment.

A multi-institutional observational study on the effects of three-dimensional radiotherapy and weekly 40-mg/m cisplatin on postoperative uterine cervical cancer patients with high-risk prognostic factors.

Background: The aim of this study was to evaluate the effects of treatment with both three-dimensional radiotherapy (3DRT) and weekly 40-mg/m cisplatin on postoperative uterine cervical cancer patients with high-risk prognostic factors.

Methods: We conducted a retrospective multi-institutional chart review of postoperative uterine cervical cancer patients with high-risk prognostic factors who had been treated with both 3DRT and weekly 40-mg/m cisplatin from 2007 to 2012. Each participating hospital provided detailed information regarding patient characteristics, treatment outcomes, and treatment complications.

The transmembrane protease serine (TMPRSS3/TADG-12) D variant: a potential candidate for diagnosis and therapeutic intervention in ovarian cancer.

The purpose of this study was to examine the expression of splice variants of the TADG-12 (TMPRSS3) gene in normal ovarian epithelial tissue and ovarian carcinoma and further to associate the expression of TADG-12 variant with clinicopathologic characteristics if such an association exists. TADG-12D variant expression was examined by semiquantitative PCR in 50 ovarian tumors [41 adenocarcinomas, 3 low malignant potential (LMP) tumors, and 6 adenomas] and 7 normal ovaries. In carcinomas as well as LMP tumors and adenomas, TADG-12D variant mRNA expression was significantly elevated compared to that in normal ovary samples.
