Evidence-based guidelines for treatment of cervical cancer in Japan: Japan Society of Gynecologic Oncology (JSGO) 2007 edition.

Clinical practice guidelines for gynecologic cancers have been published by the National Comprehensive Cancer Network and the National Cancer Institute. Whereas these guidelines form the basis for the standard of care for gynecologic malignancies in the United States, it has proven difficult to institute them in Japan due to differences in patient characteristics, health-care delivery systems, and insurance programs. Therefore, evidence-based guidelines for treating cervical cancer specifically in Japan have been under development. The Guidelines Formulation Committee and Evaluation Committee were independently established within the Committee for Treatment Guidelines for Cervical Cancer. Opinions from within and outside the Japan Society of Gynecologic Oncology (JSGO) were incorporated into the final draft, and the guidelines were published after approval by the JSGO. These guidelines are composed of ten chapters and comprise three algorithms. Each chapter consists of a clinical question, recommendations, background, objectives, explanations, and references. The objective of these guidelines is to clearly delineate the standard of care for cervical cancer treatment in Japan in order to ensure equitable care for all Japanese women diagnosed with cervical cancer.

MR-guided transvaginal cryotherapy of uterine fibroids with a horizontal open MRI system: initial experience.

PURPOSE: We evaluated the feasibility of MR-guided transvaginal cryotherapy for treating intramural, submucosal, and sub-serosal uterine fibroids with a horizontal open MRI system. MATERIALS AND METHODS: Using an MR-compatible cryotherapy system and a horizontal magnetic open-configuration MR scanner, we performed transvaginal cryotherapies using a Cusco speculum on eight uterine fibroids whose longest diameter ranged from 2.9 to 10.0 cm. We assessed the ratio of pre-treatment to post-treatment volume of the uterine fibroids as well as the patients' symptoms (anemia, abdominal pain, dysfunctional uterine bleeding, etc.). RESULTS: All procedures were carried out safely and accurately without any complications that required surgical treatment. MRI enabled clear visualization of the cryoneedle and freezing area as band-like and ellipsoid-like signal losses, respectively. The mean ratio of reduction in uterine fibroid volume was 31.0% at 9-12 months (0-75.0%). Symptoms caused by uterine fibroids improved in seven cases. CONCLUSION: This is the first report on a transvaginal approach to cryotherapy for uterine fibroids. MR-guided transvaginal cryotherapy appears to be feasible and promising as a minimally invasive therapy for symptomatic uterine fibroids.
