Asian society of gynecologic oncology workshop 2010 / 부인종양

This workshop was held on July 31-August 1, 2010 and was organized to promote the academic environment and to enhance the communication among Asian countries prior to the 2nd biennial meeting of Australian Society of Gynaecologic Oncologists (ASGO), which will be held on November 3-5, 2011. We summarized the whole contents presented at the workshop. Regarding cervical cancer screening in Asia, particularly in low resource settings, and an update on human papillomavirus (HPV) vaccination was described for prevention and radical surgery overview, fertility sparing and less radical surgery, nerve sparing radical surgery and primary chemoradiotherapy in locally advanced cervical cancer, were discussed for management. As to surgical techniques, nerve sparing radical hysterectomy, optimal staging in early ovarian cancer, laparoscopic radical hysterectomy, one-port surgery and robotic surgery were introduced. After three topics of endometrial cancer, laparoscopic surgery versus open surgery, role of lymphadenectomy and fertility sparing treatment, there was a special additional time for clinical trials in Asia. Finally, chemotherapy including neo-adjuvant chemotherapy, optimal surgical management, and the basis of targeted therapy in ovarian cancer were presented.

Apoptotic and proliferative activity in ovarian benign, borderline and malignant tumors / 中国医学科学杂志(英文版)

<p><b>OBJECTIVE</b>To determine the apoptotic and proliferative activities in various ovarian epithelial tumors.</p><p><b>METHODS</b>Formalin-fixed, paraffin-embedded tissues of 86 ovarian epithelial tumors, including 52 adenocarcinomas, 23 borderline tumors and 11 cystadenoma, were retrieved. Apoptotic (AI) and proliferative (PI) index were estimated using the monoclonal antibodies: M30, Ki-67 and Ki-S1 in these tumors. Quantitative assessment of AI and PI was estimated by calculating the percentage of positive cells among no less than 1000 tumor cells.</p><p><b>RESULTS</b>Statistically significant difference in AI was found between benign and borderline tumors or carcinomas (P = 0.028, 0.001, respectively). Significant differences in PI, as assessed by both Ki-67 and topo IIalpha, were demonstrated between carcinomas and benign or borderline tumors (both P < 0.001). Benign tumors had both low PI and AI; borderline tumors had lower PI but higher AI, while adenocarcinomas had both high proliferative and high apoptotic rates. Among borderline tumors, serious tumors had significantly lower AI and higher PI than mucinous ones.</p><p><b>CONCLUSION</b>The results suggest that apoptotic and proliferative activities play important roles in the pathogenesis and development of ovarian borderline and malignant tumors. The high apoptotic rate in borderline tumor may explain its relatively indolent behavior while the high proliferative rate in carcinomas tends to explain its aggressive behavior.</p>
