Lymphadenectomy and chemotherapy are effective treatments for patients with 2023 international federation of gynecology and obstetrics stage IIC-high risk endometrial cancer in Japan.

Background: In early-stage endometrial cancer (EC), the treatment of aggressive histological subtypes (endometrioid carcinoma grade 3, serous carcinoma, clear-cell carcinoma, undifferentiated carcinoma, mixed carcinoma, and carcinosarcoma) is controversial. We aimed to investigate the treatment of patients with International Federation of Gynecology and Obstetrics (FIGO) stage IC and stage IIC EC according to the 2023 classification.

Methods: We retrospectively identified patients with FIGO 2023 stage IC, IIC-intermediate risk (IIC-I), and IIC-high risk (IIC-H) EC who underwent adjuvant therapy or observation after surgery at eight medical institutions from 2004 to 2023.

Efficacy and safety of olaparib, olaparib plus bevacizumab and niraparib maintenance treatment in Japanese patients with platinum-sensitive advanced ovarian cancer.

Objective: To investigate whether maintenance treatment could be safely and effectively performed with olaparib, olaparib plus bevacizumab and niraparib in platinum-sensitive advanced ovarian cancer at multiple institutions in Japan.

Methods: We investigated progression-free survival and adverse events in 117 patients with platinum-sensitive advanced ovarian cancer treated with maintenance therapy.

Results: The median progression-free survival of 117 patients was 20.

Relationship Between Hematological Toxicities During Maintenance Treatment and During Chemotherapy Before Maintenance Treatment in Patients With Platinum-sensitive Relapsed Ovarian Cancer.

Background/aim: To determine if maintenance treatment can be performed effectively and safely in patients with platinum-sensitive relapsed ovarian cancer.

Patients And Methods: We carried out a multi-center study to investigate progression-free survival (PFS) and adverse events (AEs) in 229 patients receiving maintenance treatment for platinum-sensitive relapsed ovarian cancer.

Results: The median PFS in the 229 patients with maintenance treatment was 14.

Surgical skill and oncological outcome of laparoscopic radical hysterectomy: JGOG1081s-A1, an ancillary analysis of the Japanese Gynecologic Oncology Group Study JGOG1081.

Objectives: We investigated whether surgical skill and procedure were related to oncological outcomes in cervical cancer patients who underwent Laparoscopic Radical Hysterectomy (LRH).

Methods: We previously assessed data of LRH from 251 patients with FIGO stage (2009) IA2, IB1and IIA1 cervical cancer collected for JGOG 1081s study. 1) The JGOG 1081s cohort study was re-examined to refine the surgical details and extend the follow-up period as chart review.

Role of alpha-tocopherol in the regulation of mitochondrial permeability transition.

We previously showed that Ca2+-induced cyclosporin A-sensitive membrane permeability transition (MPT) of mitochondria occurred with concomitant generation of reactive oxygen species (ROS) and release of cytochrome c (Free Rad. Res.38, 29-35, 2004).

[Endoscopic surgery for gynecologic malignancy--less invasive, more radical].

The development of endoscopic equipment and surgical skills make more complicated procedures possible laparoscopically. The application of these techniques to oncologic surgery, which used to be basically the most invasive procedure, has become an important issue when considering patient well-being. For cervical and endometrial cancer we can perform a simple hysterectomy, type II or a type II radical hysterectomy as well as a pelvic and para-aortic lymphadenectomy.
