 - Female patients of childbearing potential i.e. premenopausal, no hysterectomy must have a normal plasma beta human chorionic gonadotropin bHCG within 24 hours prior to enrolling in the study due to the possible teratogenic effect. Patients with an elevated bHCG will undergo appropriate evaluation to rule out pregnancy i.e. referral to Gyn service, pelvic ultrasound and if pregnancy is ruled out and elevated bHCG is determined to be of tumor origin, patients will be permitted to proceed on study.
