Multicenter Clinicopathological Study of High-Grade Serous Carcinoma Presenting as Primary Peritoneal Carcinoma.

Objective: We conducted a multicenter clinicopathological study to characterize patients with high-grade serous carcinoma presenting as primary peritoneal carcinoma (clinical PPC).

Methods: At 9 sites in Japan, patients with clinical PPC diagnosed according to Gynecologic Oncology Group criteria were enrolled retrospectively. The Gynecologic Oncology Group criteria allow for minor ovarian involvement by high-grade serous carcinoma.

Human Papillomavirus Test for Triage of Japanese Women With Low-Grade Squamous Intraepithelial Lesions.

We evaluated high-risk human papillomavirus (HR-HPV) DNA testing for high-grade cervical intraepithelial neoplasia (CIN) lesions by cobas HPV test and diagnostic HPV16/18 genotyping in Japanese women with low-grade squamous intraepithelial lesions. Of 357 patients, HR-HPV positivity prevalence was 75.6%, and 21.

Performance of p16INK4a/Ki-67 immunocytochemistry for identifying CIN2+ in atypical squamous cells of undetermined significance and low-grade squamous intraepithelial lesion specimens: a Japanese Gynecologic Oncology Group study.

Background: p16(INK4a) immunohistochemistry has revealed a high rate of positivity in cervical intraepithelial neoplasia grade 2 (CIN2) and more severe conditions (CIN2+). The Lower Anogenital Squamous Terminology Standardization project proposed p16(INK4a) immunohistochemistry as an ancillary test for CIN. Immunocytochemistry involving dual staining for p16(INK4a) and Ki-67 in the triage of atypical squamous cells of undetermined significance (ASCUS) and low-grade squamous intraepithelial lesions (LSIL) is reported to be useful in the identification of CIN2+.

[Chemotherapy and hormone therapy for uterine sarcomas].

Uterine sarcomas are relatively rare mesenchymal malignant neoplasms with poor prognosis, accounting for 8%of all uterine malignant neoplasms. There are only a few moderately active cytotoxic agents for this entity, and therefore, chemotherapy for uterine sarcomas is palliative in most cases. According to traditional classification systems, uterine sarcomas encompass carcinosarcoma(CS), leiomyosarcoma(LMS), and endometrial stromal cell sarcoma(ESS).

A subserosal uterus-like mass presenting after a sliding hernia of the ovary and endometriosis: a rare entity with a discussion of the histogenesis.

Objective: To report the first case of a subserosal uterus-like mass.

Design: Case report.

Setting: A community-based hospital.
