Effectiveness of opportunistic screening for cancer of the cervix uteri

摘要

The incidence and mortality of uterine cervical cancer in the Maltese Islands has remained relatively constant in medical records of the last few decades. The aim of this study was to determine the cervical cancer screening history and other characteristics of the invasive cervical cancer cases diagnosed in Malta between 1992 and 2002, from a review of their medical records. Only 5% of the cases reviewed had had regular cervical smears prior to the diagnosis of the invasive lesion. Well organised national cancer screening programmes overseas indicate that if less than 70% of the target population (ages 20 to 65 for cervix) is regularly screened, the incidence and mortality will not decrease.1 In Malta, cervical screening is opportunistic and the percentage and sectors of the target population being screened is unknown. A national study is needed to quantify the number of women undergoing cervical screening and to assess how much of the relevant target population is being screened.
