上海市嘉定区肺癌疫情动态及其特点分析

目的掌握上海市郊９０年代肺癌疫情动态。方法分析嘉定区５０万人口，１９８８～１９９８年确诊并随访的１５６５例肺癌临床资料。结果发病率为２９．６／１０万；死亡率为２６．３／１０万，均较前有所上升。发病高峰为６０岁以上老年人，占７３．８％。男女患者之比３．６∶１，女性发病呈增高趋势。地区、职别发病率无明显差异，与同受环境污染、职业致病因子影响有关。９７．２％病例就诊确诊。按ＴＮＭ分期：Ⅰ期１１．３％，Ⅱ期２１．５％，Ⅲａ期３６．４％，Ⅲｂ期２１．９％，Ⅳ期８．９％。手术治疗占１１．４％。１年生存率３１．８％，５年生存率仅３％，与老年患者比例高、病人就诊过晚、延误诊断、晚期病例多等影响治疗有关。结论综合治理环境，对易患人群监测，早发现、早治疗，仍为防治肺癌的当务之急。
