Linear trend analysis of patients with cervical cancer treated at the Institute of Oncology Vojvodina in 2001-2007.

Purpose: Cervical cancer is the leading cause of death in women with gynecological cancers in Vojvodina. Serbia currently holds the leading place in Europe regarding the incidence of cervical carcinoma and comes second in terms of mortality.
Methods: Data were retrieved from the Register for malignant neoplasms of the Institute of Oncology Vojvodina for the period 2001-2007. The patients were divided in 3 groups according to the stage of disease based on the FIGO classification for cervical cancer. Data were analysed using linear trend and t-test.
Results: The linear trend of the number of registered cases in the group of stage I-IIA patients during 7 years showed no significant change in the prevalence of the disease. In the group of women diagnosed with stage IIB no statistical difference regarding either a rising or a decreasing trend was observed. The observed trend in an advanced disease stage (III and IV) showed a slight decrease in the number of patients, but without statistical significance.
Conclusion: The linear trend of the number of patients with cervical carcinoma during a 7-year period points to the fact that the number of newly detected cases of advanced disease stages did not decrease significantly despite the affordable and simple methods of early detection. This result underlines the importance of implementation of a National screening programme in the general population for early detection of cervical neoplasms. The excellent results of National screening programmes in other European countries lend support to this approach.
