Robotic dual-docking surgery for para-aortic lymphadenectomy in endometrial cancer: a prospective feasibility study.

Background: The standard for robotic para-aortic lymphadenectomy has not been fully established. Para-aortic lymphadenectomy performed by sharing the same ports with pelvic procedures, a procedure known as dual-docking surgery, can be performed using the latest robotic system. We prospectively examined the ability of standardized dual-docking robotic surgery in endometrial cancer patients.

Peritoneal natural killer cell chemotaxis is decreased in women with pelvic endometriosis.

Problem: NK cell and macrophage function are decreased in endometriosis, and the disease may involve reduced immune surveillance in the peritoneal cavity. NK cell cytotoxicity and migration ability (chemotaxis) are considered important; the former has been investigated, but the latter has not.

Method Of Study: We compared chemotaxis of immunocompetent cells (NK cells, macrophages, T cells) in peritoneal fluid obtained during laparoscopy in 27 women with and 13 without endometriosis.

One-step nucleic acid amplification (OSNA) assay for detecting lymph node metastasis in cervical and endometrial cancer: a preliminary study.

Objective: To evaluate the accuracy of the one-step nucleic acid amplification (OSNA) assay for the diagnosis of lymph node (LN) metastasis in uterine cancer.

Methods: A total of 116 LNs from 30 patients with cervical and endometrial cancer, enrolled in this prospective study, were used. Excised LNs were cut into 4 to 6 blocks at 2 mm intervals, and nonadjacent blocks were alternately subjected to either histological examination or the OSNA assay.

Comparison of radio-isotope method with 99m technetium and near-infrared fluorescent imaging with indocyanine green for sentinel lymph node detection in endometrial cancer.

Background: We aimed to compare the detection rate of pelvic sentinel lymph node between the radio-isotope with 99m technetium (99mTc)-labeled phytate and near-infrared fluorescent imaging with indocyanine green in patients with endometrial cancer.

Methods: This study included 122 patients who had undergone sentinel lymph node mapping using 99mTc and indocyanine green. In the radio-isotope method, sentinel lymph nodes were detected using uterine cervix 99mTc injections the day before surgery.

Zinc supplementation during chemotherapy for gynecological malignancy.

Objective: To determine the significance of zinc supplementation for zinc deficiency during chemotherapy for gynecologic malignancies.

Methods: Twenty-eight patients suspected of zinc deficiency before chemotherapy were prospectively evaluated. Gustatory test, serum zinc, blood count, and biochemical examinations were made pre-chemotherapy at 3- and 6-week intervals.

The use of bevacizumab is correlated with improved post-progression survival in advanced recurrent ovarian cancer.

Background: The recent improvements in anti-cancer therapy following first-line treatment can potentially impact post-progression survival. We evaluated the factors that influence post-progression survival in advanced recurrent ovarian cancer.

Methods: Eighty-nine patients who underwent first-line treatment between June 2005 and December 2017 were included.

Importance of Cervical Elongation Assessment for Laparoscopic Sacrocolpopexy.

Cervical elongation in patients with pelvic organ prolapse (POP), who previously underwent laparoscopic sacrocolpopexy (LSC), is not fully understood. We report a case of a second surgery for endometrial cancer complicated with POP recurrence, which seemed to be related to cervical elongation following LSC. A 65-year-old woman was referred for invasive treatment following LSC.

Correlation of World Health Organization 2010 Classification for Gastroenteropancreatic Neuroendocrine Neoplasms with the Prognosis of Ovarian Neuroendocrine Neoplasms: Kansai Clinical Oncology Group-Protocol Review Committee/Intergroup Study.

Background: In 2014, the World Health Organization (WHO) released a classification system introducing neuroendocrine neoplasms (NENs) of the female reproductive tract, excluding the ovaries. This study aimed to evaluate whether retrospective adaption of the gastroenteropancreatic (GEP)-NEN classification is feasible for ovarian NENs (O-NENs) and correlates with prognosis.

Methods: Sixty-eight patients diagnosed with carcinoid, small cell carcinoma (pulmonary type), paraganglioma, non-small/large cell neuroendocrine carcinoma (NEC), mixed NEC, or undifferentiated carcinomas at 20 institutions in Japan were included in this retrospective cross-sectional study.

Current status of tertiary debulking surgery and prognosis after secondary debulking surgery for recurrent Müllerian epithelial cancer in Japan: a retrospective analysis of 164 patients (KCOG-G1402).

Background: This study aimed to evaluate the current status of secondary debulking surgery (SDS) and tertiary debulking surgery (TDS; performed for recurrence after SDS) and to assess the overall survival after recurrence of Müllerian epithelial cancer in Japan. We also evaluated the data of patients who underwent a fourth debulking surgery (i.e.
