简介:目的:探讨男性肿瘤患者化疗后勃起功能状况。方法:选取我院2011年1月至2013年12月间的50例初次接受化疗的男性肿瘤患者为研究对象,采取国际勃起功能指数-5(IIEF-5)进行评估化疗前后勃起功能状况。结果:治疗有效率为58.0%。其中,CR14例,PR15例,PD21例,SD0例。化疗前勃起功能障碍32.0%,化疗后勃起功能障碍83.0%,化疗前后勃起功能障碍发生率比较差异有统计学意义(P<0.05);化疗后消化道肿瘤、鼻咽癌、肺癌、淋巴瘤、软组织肿瘤患者IIEF-5评分较化疗前有不同程度的降低,差异有统计学意义(P<0.05)。化疗后不同病理类型间IIEF-5评分比较无统计学意义(P>0.05)。结论:临床中男性肿瘤患者实施化疗后会增加勃起功能障碍,增加其发病率。
简介:目的:总结早期卵巢恶性肿瘤患者保留生育功能术后5年内生存率、再妊娠情况及卵巢激素变化,以提高临床认识。方法:收集32例经病理证实并有完整临床随访资料的早期卵巢恶性肿瘤患者,所有患者均行保留生育功能术,分别于术后6个月、12个月、24个月、36个月、48个月、60个月记录并对比患者生存率、再妊娠情况及性激素六项水平。结果:32例患者术后6个月、12个月、24个月、36个月、48个月、60个月生存率分别为100%、93.8%、93.8%、90.6%、87.5%、87.5%;32例患者共妊娠42次,所有患者子女5年随访期间健康无畸形;32例患者均行术后辅助化疗,18例患者辅助化疗期间停经或月经减少,停止化疗半年后,所有患者月经恢复正常;32例患者月经恢复后性激素六项均位于正常范围内;患者化疗前与化疗后性激素六项水平无统计学意义(P〉0.05)。结论:保留生育功能术对于早期卵巢恶性肿瘤患者是相对安全、可行的,值得临床进一步研究。
