[Cervical cancer in Frederiksborg County 1990-1991].

One hundred and eight patients from Frederiksborg County, Denmark with cervical cancer diagnosed from 1990 to 1993 were analysed concerning type of carcinoma, tumour stage and screening history. The following types of carcinoma were found: 87 (81%) squamous, 5 (5%) adenosquamous, 15 (14%) adenocarcinoma and one (1%) small cell carcinoma. All women aged 23-60 receive a written invitation to participate in the screening programme. Of the 57 patients who had never or only sporadically been screened 23 were outside the target population. Tumour stage was generally higher for the non-screened, i.e. only 57.9% stage I compared to 82.4% for the screened population. In 51 cases the following errors had occurred: seven sampling errors, 21 screening errors, 15 lack of follow-up of abnormal or inadequate smears, six inadequate cryotherapy and two interval cancers.
