This is a non-blinded, non-randomized, non-interventional prospective cohort study to evaluate the prevalence of adrenal suppression in gynecologic cancer patients undergoing chemotherapy regimens requiring concurrent dexamethasone. Women with gynecologic cancers (including cervical, endometrial, ovarian, fallopian tube, or primary peritoneal cancers) who are scheduled to begin chemotherapy with any of the standard chemotherapy regimens that also receive dexamethasone. After informed consent is obtained, they will have peripheral blood samples drawn at the time of routine blood draw for (ideally a fasting morning) cortisol level at three different times in their routine care. Patients will also answer a quality of life questionnaire at the times of these blood draws to assess for symptoms associated with treatment (nausea, vomiting, fatigue). A total of 80 subjects will be recruited to participate. 40 subjects will be given chemotherapy regimens receiving dexamethasone with three chemotherapy treatments in a three week cycle. 40 subjects will be given chemotherapy regimens receiving dexamethasone with one chemotherapy treatment in a three week cycle.
