[Simultaneous screening of cancers of the breast, cervix, colon and rectum. The Isère experience].

The mass screening program for cancer in the Isere department offers women between 50 and 69 years a medical consultation and three tests: mammography for breast cancer screening, Pap smear for cervical cancer screening, and hemoccult for colorectal cancer. During the first round, 29,570 women took part in the program, 21% had a mammography, 20% Pap smears and 25% a hemoccult. In breast cancer screening, the rate for further examination was 11.9%, the breast cancer detection rate was 5.4 per 1,000 women screened and the detection rate of invasive tumor < or = 10 mm: 2.0 per 1,000. In cervical cancer screening, the rate of abnormal examinations was 1.2%. The cervical cancer detection rate was 1.5 per 1,000. The rate of positive hemoccult was 2.7% and the rate of colorectal cancers and polyps 10 mm or larger was 2.7 per 1000. Results of screening are satisfying, but compliance rate is too low. Acceptance rate must be examined in following rounds.
