Abstract

Some pathological findings and prognostic indices recorded in breast cancer cases, detected, on one hand, by a provider-initiated mammography screening program (Group 1), and, opportunistically, in self-referred symptomatic women (Group 2) on the other, are compared. In 8877 symptom-free women, aged 50-65 years, individually invited to attend the screening offered for the residents of the III., XII. and XIII. districts of Budapest, 67 cancer cases were detected (7.5 in 1000 screenees), in accordance with the cancer detection rate of the first, "prevalence" round of organised screening programmes. In the other group of 1593 symptomatic, self-referred women of the same age, 113 cancer cases were diagnosed by mammography. As far as the pathological parameters are concerned, the number of cases with invasive cancer less than 15 mm in diameter, and those with axillary nodes present was found to be significantly higher in the screened group as compared to the self-referred one (p <0.01). In "small" cancers (i.e. less than 15 mm in diameter), no significant difference was found in the proportion of histologic grade III tumours among the two groups. In screen-detected cancers both the morphometric prognostic index (as calculated by Baak et al.) and the Nottingham Prognostic Index (NPI) proved to be more favourable, as compared to those in the self-referred group. The p-value as determined by Mann-Whithey test was 0.000003 in the screened group, and 0.000015 in the other one. These findings provide convincing evidence in support of the public health importance of provider-initiated, organised mammography screening for breast cancer, therefore, the introduction on service basis of organised breast screening into the health care system in Hungary is strongly recommended by the authors.
