Adenosquamous carcinoma of the cervix: prognosis in stage IB.

The outcome of women with adenosquamous carcinoma of the cervix has been a controversial issue. To assess the prognostic significance of this cell type, the medical records of 29 patients with stage IB primary adenosquamous carcinoma of the cervix were reviewed. Twenty-six had cervical tumors measuring 3 cm or less. With a median follow-up of 60 months, the overall disease-free 5-year survival was 85%. Pelvic lymph node metastases were found in three of 19 patients (16%) with stage IB, and periaortic lymph nodes were negative in eight. A log-likelihood chi 2 test comparing lymphatic spread, recurrence rate, and 5-year disease-free survival in patients with stage IB disease and tumors less than 3 cm versus a similar group of 58 patients with pure squamous cell carcinoma of equivalent stage and comparable size treated during the same time disclosed no significant differences in any of the indicators analyzed. We conclude that stage IB adenosquamous carcinoma of the cervix does not differ in its metastatic potential or outcome from the more common pure squamous cell carcinoma.
