[Organized cervical cancer screening for underpriviledged women]

Individual cervical screening with pap-smears is the major cause of the decrease in incidence and mortality of cervical cancer in France since more than 30 years. But, for the last ten years, the decrease in mortality is limited due to the persistence of poor prognostic cases and the insufficiency of treatment efficacy in such patients. These cases are mostly observed in women who did not participate to regular screening. They are generally from low socioeconomic levels or migrant populations, or both. Such an observation leads us to organize 3 successive pilot campaigns (2001, 2003, 2005) in the Northern part of Marseille city where the rate of such poor population is high (37 to 45%). The women without a pap-smear indexed in the National Insurance Register for the last 3-2 years were invited by individual mailing to perform, free of charge, a pap-smear. The evaluation of each campaign helps us to improve the next one. The major changes from the 1st one to the 3rd one were to increase the number of free screening services, to send a second invitation to the non responders, and to organize local meetings with social workers and nurses to explain to the women the importance of performing regular screening tests. The final results after the 3 campaigns showed : out of the eligible women the participation rates are dramatically low evolving from 1,56 % to 2,48% and 6,87% of pap-smears done along the 3 campaigns ; the selection of women "without pap-smear" from the national Insurance register was not good, a great number of missing data was identified, explaining partly the extremely low rate of participation ; the factors increasing a little the participation are the second mailing of invitation (39 % of pap-smears realised) ; the total gratuitous of the screening (both sampling and reading) ; the oral information delivered locally by social workers and the proximity of the places to perform the test ; the quality of the pap-smears collected by gynecologists was good but insufficient for other health professionals, requiring a specific training for cervical cell collection. The organization of such pilot projects need to be followed to find better solutions to increase the participation to cervical screening of such populations who are at high risk of poor prognosis cervical cancers.
