    • Background: The effectiveness of cervical cancer screening programs differs widely in different populations. The reasons for these differences are unclear. Routine and comprehensive audits have been proposed as an ethically required component of screening. We performed a nationwide audit of the effectiveness of the Swedish cervical cancer screening program.Methods: We identified all invasive cervical cancer cases that were diagnosed in Sweden from January 1, 1999, through December 31, 2001, and had been reported to the Swedish Cancer Registry (n = 1230 cases). We verified the diagnoses by histopathologic rereview and matched each case subject to five (population-based) age-matched control subjects who were identified from the National Population Register. The Pap smear screening histories for case and control subjects were reviewed for a 6-year period using the National Cervical Cancer Screening Register, which contains data on essentially all relevant cytological and histological diagnoses in Sweden. Odds ratios (ORs), and their 95% confidence intervals (CIs), of cervical cancer according to screening history were calculated in conditional logistic regression models. All statistical tests were two-sided.Results: Women who had not had a Pap smear within the recommended screening interval had higher risk of cervical cancer than women who had been screened (OR = 2.52, 95% CI = 2.19 to 2.91). This risk was similarly increased for all age groups (Phomogeneity = .96). The risk for nonsquamous cell cervical cancers (OR = 1.59, 95% CI = 1.20 to 2.11) was also increased. Women who had not had a Pap smear within the recommended screening interval had a particularly high risk of advanced cancers (OR = 4.82, 95% CI = 3.61 to 6.44). Among women who had been screened within the recommended interval, those with abnormal Pap smears had a higher risk of cervical cancer than those with normal smears (OR = 7.55, 95% CI = 5.88 to 9.69) and constituted 11.5% of all women with cervical cancer.Conclusions: Nonadherence to screening intervals was the major reason for cervical cancer morbidity. The screening program was equally effective for women of all ages and was also effective against nonsquamous cancers.

  • Risk of invasive cervical cancer in relation to clinical investigation and treatment after abnormal cytology: a population-based case-control study.
  • 2011
  • Ingår i: International journal of cancer. - Malden : Wiley. - 1097-0215 .- 0020-7136. ; 129:6, s. 1450-8

    • A substantial proportion of women with cervical cancer that have participated in cervical screening have a history of an abnormal cytology result. Our objective was to assess the impact of histological investigation and treatment of women with abnormal cytology on the subsequent risk of invasive cervical cancer. All invasive cervical cancer cases in Sweden 1999-2001 and five population-based control women per case were investigated. Clinical investigations and treatment were analysed in case women (N = 143) and control women (N = 176) below 67 with abnormal cytology results 0.5-6.5 years before the cases' diagnosis. Cervical cancer risk in relation to investigation [histology or not, punch biopsy, cervical curettage or cone/large loop excision of the transformation zone (LLETZ)], and treatment (treatment or not, excisional or ablative) was estimated as odds ratios (ORs) using logistic regression. Absence of histological assessment was associated with increased cancer risk, both after low-grade [OR 2.37; 95% confidence intervals (CI): 1.27-4.43] and high-grade squamous atypia (8.26; 2.37-28.8). Among women with histology, absence of treatment was associated with increased cancer risk (3.68; 1.53-8.84), also when biopsy showed low-grade atypia or normal findings (3.57; 1.18-10.8). Ablative therapy associated with increased risk compared with excisional (3.82; 1.01-14.4), and laser conisation associated with decreased risk compared with LLETZ (0.06; 0.01-0.36). In conclusion, low-grade as well as high-grade squamous atypical cytology results may warrant histological investigation, treatment reduced cancer risk even when histology was negative or showed low-grade atypia indicating a need for improvements in the diagnosis of high-grade lesions, and laser conisation was the most effective treatment.
