简介:摘要目的探讨宫颈癌的临床病理特点及防治措施。方法收集我院2004年1月至2013年12月间经病理组织学证实的323例宫颈癌患者的临床资料并进行临床病理学分析和探讨。结果发病年龄,23~74岁,<35岁68例(21.05%),以接触性阴道出血、白带增多为主要症状;36~55岁161例(49.85%),以接触性阴道出血及月经紊乱为主要症状;>55岁94例(29.10%),以不规则阴道流血或绝经后阴道流血为主要症状。结论宫颈癌发病以50岁以下居多,年轻化趋势明显,年轻妇女发病率相对较高。临床表现以接触性阴道出血及经期紊乱为主要表现形式。提倡对所有育龄妇女进行液基细胞学筛查,以防治癌前病变及早期宫颈癌。
