Objective: To report our experience with invasive carcinoma of the cer
vix during pregnancy, assessing maternal morbidity due to treatment de
lay and reporting maternal and fetal outcome. Methods: Twenty-seven pa
tients with invasive cervical cancer, who were pregnant at the time of
diagnosis or treatment, were identified from review of morbidity and
mortality statistics between January 1, 1980 and December 31, 1991. Al
l medical records were examined retrospectively. Results: The incidenc
e of cervical carcinoma in our population was 1.2 cases per 10,000 pre
gnancies. Most patients had stage I lesions. The predominant histologi
c cell type was squamous cell carcinoma, followed by adenosquamous car
cinoma and adenocarcinoma. Eight patients with stage Ia or lb cervical
cancer postponed therapy to optimize fetal outcome, with a mean diagn
osis-to-treatment interval of 144 days (range 53-212). Nineteen patien
ts elected immediate treatment, with a mean diagnosis-to-treatment int
erval of 17 days (range 2-42). Fetal outcome was uniformly good for th
e delayed-treatment group. Nine fetal deaths and two neonatal deaths o
ccurred in the immediate-treatment group. All patients who delayed the
rapy are free of disease after a median follow-up of 23 months. Conclu
sion: Deliberate delay of therapy to achieve fetal maturity appears to
be a reasonable option for patients with stage I cervical cancer comp
licating pregnancy.
