title: Efficacy of a hospital based cytology screening program.
abstract: From 1976 to 1986, a total of 117,471 women attending gynecologic outpatient departments of six hospitals in Delhi, India, were screened cytologically. The cytodiagnosis revealed 30,399 (25.9%) normal finding, 84,889 (72.3%) inflammatory changes, 1910 (1.6%) dysplasia of various grades and 213 (0.2%) malignant lesions. Of the 213 cases detected as malignant, clinical suspicion of cervical cancer was not present in 125 women (58.7%). Histologically malignancy was confirmed in 192 women (90.1%) of the 213 cytologically diagnosed malignant cases. The diagnosis revealed 94 (49.0%) as carcinoma in situ and the rest of the cases were invasive lesions. This was in contrast to only 5.2% (10/194) of cases with carcinoma in situ seen at the cancer clinic during 1983-1986 in one of the major collaborating hospitals of Delhi. The analysis of data according to age revealed that median age at detection of mild/moderate, severe dysplasia, carcinoma in situ (CIS) and invasive cancers was 34.0, 37.9, 38.6, and 47.8 years, respectively, indicating a latency period of one and a half decade from the onset of precursor lesions to invasive disease. Mass population screening in our country is not feasible in the near future and this may be true also for other developing countries. In its absence cytological screening of patients attending hospitals and maternity homes can give a large yield of early cervical cancers, which are curable.
