Twenty-five patients were evaluable. There were no objective responses, with 4 (16%) patients achieving stable disease; only 1 patient had a progression-free survival of 6 months (4%) or more. The 1-sided 90% confidence interval for response was 0.0% to 8.8%. The 2-sided 90% confidence interval for the proportion of patients surviving progression-free for at least 6 months is 0.2% to 17.6%. Erlotinib was well tolerated, with the most common drug-related adverse events being gastrointestinal toxicities, fatigue, and rash.Conclusions: Erlotinib is inactive as monotherapy in patients with recurrent squamous cell carcinoma of the uterine cervix.
