Stage Ib cervical cancer during pregnancy: planned delay in treatment--case report.

Approximately 0.05% of pregnancies are complicated with cervical cancer. Treatment of this malignancy during pregnancy depends on the stage of disease and gestational age at the time of diagnosis. In women with Stage IB cervical cancer immediate treatment, without regard to the pregnancy, is traditionally advocated in the first and second trimester. A planned delay of treatment, to achieve foetal maturity, may be acceptable if there are no adverse maternal and foetal consequences. We present a case of a Stage IB1 cervical cancer, diagnosed during a twin pregnancy, and treated with a planned delay of 19 weeks. We have reviewed the literature and focused on what is known about planned delay in therapy of Stage IB cervical cancer, diagnosed before 30 weeks of gestational age.
