【摘要】 目的建立一个实用，有效的宫颈原位癌的筛选诊断方法。方法对２５岁以上已婚妇女采用“四步”检查法。结果发现１３６例宫颈原位癌。患者平均年龄为４４．１０岁，无临床症状者占５０．７５％，宫颈光滑者为４４．７８％，宫颈糜烂者占５５．２２％。“四步”检查中，阳性率依次为８．９６％，８３．５８％、３．７３％及３．７３％。宫颈和颈管同时检查时阳性率（１００％）比单项宫颈（９０．９８％）或颈管（８４．４２％）检查的阳性率高。３５例作亚连续切片，发现宫颈１～１２点均可发生癌，以１０点处检出率最高（４８．５７％），６点处次之（４２．８６％）。结论在农村普查中采用“四步”检查法是很有实用价值的，一次涂片阴性不能完全排除癌的存在，要结合临床综合判断，同时取宫颈及颈管两个涂片。更多还原
