To determine if cytologic screening is associated with early stage at diagnosis of and decreased mortality from invasive adenocarcinoma and adenosquamous carcinoma of the uterine cervix.


We retrospectively reviewed the medical records of all 169 women diagnosed with invasive adenocarcinoma or adenosquamous carcinoma of the cervix in a prepaid health plan during 1988-1994. Differences in stage and survival were assessed in relation to screening history and symptoms.


Among the 169 cases, late-stage disease was present in 19/169 women (11.2%) at the time of diagnosis, and 24/269 (14.2%) women died of the disease during the three-year follow-up period. Women whose cancer was screen detected numbered 48/169 (28.4%) and were less likely to present with late-stage disease than non-screen-detected women: 2/48 (4.2%) versus 17/121 (14.0%) (P = .05). A mortality advantage at three years from diagnosis was associated with screen-detected cancers: 1/48 (2.1%) versus 23/121 (19.0%) (P = .002), and this advantage persisted after controlling for stage at diagnosis.


Invasive adenocarcinomas and adenosquamous carcinomas of the cervix detected by screening are found at an earlier stage and are associated with lower disease-specific mortality than those not detected by screening.
