上推膀胱直肠后再次宫颈环形电切术对保留生育功能的价值

目的:探讨上推膀胱直肠后再次宫颈环形电切术(LEEP)在宫颈疾病治疗中的可行性,评价其对年轻患者保留子宫及生育功能的价值。方法:回顾性分析2010年1月至2014年4月在复旦大学附属妇产科医院就诊,因宫颈LEEP术后切缘阳性或术后随访复发、无法在门诊行常规LEEP而行上推膀胱直肠后再次LEEP的38例患者的临床资料。结果:38例患者均顺利完成了上推膀胱直肠后再次LEEP,术中均未出现膀胱、直肠损伤等并发症。手术时间38±7分钟,术中出血量20±5 ml,住院天数2.7±0.6天;其中1例患者术前病理检查为宫颈高度鳞状上皮内瘤变,术后升级为原位鳞癌合并原位腺癌行全子宫切除术,37例患者(97.4%)成功保留子宫,随访至今1例术后12个月低度鳞状上皮内瘤变行宫颈激光治疗,余均未见宫颈病变复发。12例患者有生育意愿,7例患者已成功妊娠,6例已分娩。结论:上推膀胱直肠后再次LEEP安全可行,可实现未生育妇女及年轻妇女保留子宫及生育能力的意愿。     

Responsiveness of gynecologic tumors to chemotherapeutic agents in the 6-day subrenal capsule assay

Various gynecologic malignancies have been tested in the 6-day subrenal capsule assay, which is an in vivo test of human tumor responsiveness to drug therapy. Fresh surgical explants of ovarian, endometrial, and cervical tumors were implanted as 1-mm³ fragments under the renal capsule of normal mice and tested against a spectrum of clinically active agents. Regardless of the site of origin, human tumors showed variations in growth rate when implanted under the renal capsule that appeared to reflect both the growth potential characteristic of each tumor as well as the heterogeneity of the cell populations comprising each tumor. An average of 60% of tumors showed positive growth and 11% demonstrated no measurable change in size. The response rates of 18 ovarian, 28 endometrial, and 20 cervical carcinomas to clinically active chemotherapeutic agents were determined. A range of responses, in terms of drugs indicated to be active and of the degree of responsiveness to active agents, was obtained with each histologic type. Response rates varied from 6% to tamoxifen in cervical carcinomas to 80% to 5-fluorouracil in ovarian carcinomas. The results of this study support the variability in chemotherapy responsiveness observed clinically with gynecologic tumors and suggest the feasibility of using the subrenal capsule assay as a predictive test.     

Schwannoma en espina dorsal en gestante de 24 semanas

Schwannoma of the spine is a rare entity. The main problem caused by this tumor are the symptoms provoked by its increasing size and the consequent spinal cord compression. A peculiarity of this benign neoplasm is the presence of estrogen and progesterone receptors in Schwann cells, which has been linked to greater growth of these tumors in pregnant patients.
