Aim: This study examines patterns and predictors of site-specific recurrence to explore the causes of local recurrence of cervical cancer.

Methods: Radical hysterectomy was performed in 121 patients (stage IB-IIB). Nerve-sparing was performed whenever possible.

Objective: The survival and prognostic factors for locally advanced cervical cancer treated with nerve-sparing Okabayashi-Kobayashi radical hysterectomy have not been elucidated. We aimed to evaluate the oncological outcomes of those patients after radical hysterectomy with adjuvant chemotherapy.

Methods: This retrospective cohort study was conducted from January 2002 to December 2011.

Ovarian cancer is known for its aggressive pathological features, including the capacity to undergo epithelial to mesenchymal transition, promoting angiogenesis, metastatic potential, chemoresistance, inhibiting apoptosis, immunosuppression and promoting stem-like features. Galectins, a family of glycan-binding proteins defined by a conserved carbohydrate recognition domain, can modulate many of these processes, enabling them to contribute to the pathology of ovarian cancer. Our goal herein was to review specific galectin members identified in the context of ovarian cancer, with emphasis on their association with clinical and pathological features, implied functions, diagnostic or prognostic potential and strategies being developed to disrupt their negative actions.

Objective: Associations between the number of prior chemotherapy (CT) regimens and gastrointestinal (GI) perforation in patients receiving bevacizumab treatment has not been fully investigated. The aim of the study was to investigate the impact of ≥3 prior CT regimens on GI perforation.

Materials And Methods: We retrospectively investigated the medical records of 133 patients with gynecological cancer who received bevacizumab-containing treatment.

Importance: The role of surgery in early-stage cervical cancer has been established, but it is controversial in locally advanced cervical cancer.

Objective: To determine whether a radical hysterectomy method with extended removal of paracervical tissue for locally advanced cervical cancer is associated with satisfactory oncological outcomes.

Design, Setting, And Participants: This retrospective cohort study was conducted from January 1, 2002, to December 31, 2011, and participants were patients with cervical cancer at a single tertiary center in Northern Japan.

Objective: The aim of this study was to investigate a magnetic resonance imaging-based definition of lower uterine segment carcinoma.

Methods: We retrospectively reviewed 587 consecutive patients with endometrial cancer who underwent hysterectomy. Lower uterine segment carcinoma was determined through pathological examination and magnetic resonance imaging assessment.

Objective: This study evaluated outcomes of laser vaporization of the cervix for women with cervical intraepithelial neoplasia (CIN)-3.

Methods: We retrospectively reviewed 161 consecutive patients with CIN3 who were treated with cervical laser vaporization between January 2008 and December 2012. At each follow-up visit, histologically confirmed CIN2, CIN3 and invasive carcinoma were defined as treatment failures, as were high-grade squamous intraepithelial lesion (HSIL) or atypical squamous cells that cannot exclude HSIL with subsequent treatment or lost to follow-up.

Objective: The aim of this study was to investigate the feasibility of sentinel lymph node mapping characterized by a cervical tracer injection in endometrial cancer.

Materials And Methods: This retrospective study was carried out using data for 57 patients with endometrial carcinoma who had undergone intraoperative sentinel lymph node mapping and subsequent surgical staging. Technetium colloid and/or indocyanine green was injected into the uterine cervix and a gamma-detecting probe and/or photodynamic eye camera system was used intraoperatively to locate hot spots.

Objectives: This study evaluated the therapeutic significance of full lymphadenectomy in early-stage ovarian clear cell carcinoma (OCCC).

Methods: We retrospectively reviewed records of 127 consecutive patients with pT1/pT2 and M0 OCCC who were treated between January 1995 and December 2015. We compared survival outcomes between those who did and did not undergo para-aortic lymph node dissection (PAND), and analyzed independent prognostic factors (Cox proportional hazards model with backward stepwise elimination).

Background: The therapeutic significance of neoadjuvant chemotherapy (NAC) followed by radiation therapy (RT) was negated during the early 1990s. Here, we compared post-NAC RT to surgery for chemo-sensitive cervical squamous cell carcinoma (SCC).

Methods: This study included 79 consecutive patients with cervical SCC who were treated by NAC followed by surgery (n = 49) or by definitive RT (n = 30).

We encountered an elderly married couple with concurrent vulvar and penile carcinoma with an Asian variant of human papillomavirus type 16. Asian variants might have an elevated risk of concurrent external genital carcinomas of a male and a female, and analysis of human papillomavirus variants might be important to understand the mechanism of carcinogenesis.

Objective: The aim of this study was to evaluate the clinical behavior and management outcome of recurrent endometrial stromal sarcoma (ESS).

Methods: A retrospective review of charts of 10 patients with recurrent ESS was performed and relapse-free interval, relapse site, treatment, response to treatment, duration of follow-up and clinical outcome extracted. Survival outcome measures used were post-relapse survival which was defined as the time from first evidence of relapse to death from any cause.

This literature review was conducted to provide better counsel to pregnant women who erroneously took angiotensin receptor blockers (ARBs) during the second and/or third trimesters regarding infant outcomes. Information was available on 83 fetuses in 34 literature reports, including one that we encountered recently. Fourteen pregnancies were terminated, and six were unknown regarding status of amniotic fluid volume (AFV).

We encountered a 63-year-old woman who had a uterine tumor with peritoneal dissemination and para-aortic lymph node metastasis. Microscopic specimens of the tumor showed a small blue round-cell tumor. Immunohistochemistry showed cells to be negative for cytokeratin AE1/3, desmin, myogenin, CD10, CD34, and CD99, focal positive for vimentin, and positive for muscle-specific actin (HHF-35), neurofilament, synaptophysin and CD56.

Endometrial stromal sarcoma is known to be a hormone-dependent tumor. Efficacy of hormonal therapy including high-dose progestins, aromatase inhibitors or gonadotropin-releasing hormone analogs has been reported. We report a case of recurrent endometrial stromal sarcoma, the tumor cells of which were strongly positive for CD10, estrogen and progesterone receptors.

Cerebral recurrence from Müllerian cancer is a rare event and prognosis of patients with such a condition is poor. We report a case of cerebral recurrence from International Federation of Gynecology and Obstetrics classification stage IV tubal cancer presenting with inguinal lymphadenopathy. The patient achieved more than 7 years' disease-free survival after irradiation to the brain despite the inauspicious event.
