A retrospective review of cervical cytology in women developing invasive squamous cell carcinoma.

Abstract

The records of 93 women who presented with invasive squamous cell carcinoma were searched for evidence of cervical cytology during the years preceding this diagnosis; a search was also made through the files of local laboratories and contact was made with general practitioners and relevant hospital departments. Only 26 (28%) of these 93 women had had a cervical smear at any time before the diagnosis of invasive cancer, and only 11 (12%) had had regular cytological surveillance. Fifteen (60%) had had a smear taken and reported as negative within the previous 5 years, six (6%) within the previous year. Eleven of these 15 slides were obtained for review: three were regarded as positive and three more were re-classed as too scanty for conclusive assessment. In nine of the 67 women who had never had a smear, a gynaecological or obstetric examination was known to have been performed or indicated within the previous 5 years, thereby representing a missed opportunity for screening. In three patients cytological abnormalities had been reported within the previous 3 years but no action had been taken.
