Temsirolimus With or Without Megestrol Acetate and Tamoxifen Citrate in Treating Patients With Advanced, Persistent, or Recurrent Endometrial Cancer

Inclusion Criteria

• Patients must have histologically confirmed advanced (International Federation of Gynecologists and Obstetricians [FIGO] stage III or IV), persistent, or recurrent endometrial carcinoma, which is not likely to be curable by surgery or radiotherapy; histologic documentation of the recurrence is not required
• All patients must have measurable disease; measurable disease is defined as at least one lesion that can be accurately measured in at least one dimension (longest dimension to be recorded); each lesion must be >= 20 mm when measured by conventional techniques, including palpation, plain x-ray, computed tomography (CT), and magnetic resonance imaging (MRI), or >= 10 mm when measured by spiral CT
• Patients must have at least one "target lesion" to be used to assess response, as defined by Response Evaluation Criteria In Solid Tumors (RECIST); tumors within a previously irradiated field will be designated as "non-target" lesions unless progression is documented
• Prior chemoradiotherapy for a pelvic recurrence is permitted; prior chemotherapy in the adjuvant setting for stage I, II, or III disease is permitted
• Note: no prior chemotherapy in the setting of stage IV disease is permitted unless the patient was without evidence of disease at the completion of chemotherapy and had at least six months of progression-free survival since the completion of chemotherapy
• Regardless of circumstances, no more than one prior chemotherapy regimen (including chemoradiotherapy) is permitted
• Patient must be able to take p.o. medications
• Performance status must be 0-2
• Absolute neutrophil count >= 1,500/mcL
• Platelets >= 100,000/mcL
• Total bilirubin within normal institutional limits
• Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase [SGOT]) = = 3.0 mg/dL
• At least 4 weeks must have elapsed since the patient underwent any major surgery (e.g., major: hysterectomy, resection of a lung nodule-minor: a Port-A-Cath placement)
• Patients who have met the pre-entry requirements
• Patients must have signed an approved informed consent including Health Insurance Portability and Accountability Act (HIPAA) authorization

Exclusion Criteria

• Patients with Gynecologic Oncology Group (GOG) performance status of 3 or 4
• Patients cannot be receiving enzyme-inducing antiepileptic drugs (EIAEDs; e.g., phenytoin, carbamazepine, phenobarbital) nor any other cytochrome P450, family 3, subfamily A, polypeptide 4 (CYP3A4) inducer such as rifampin or St. John's wort, as these may decrease temsirolimus levels; use of agents that potently inhibit CYP3A (and hence may raise temsirolimus levels), such as ketoconazole, is discouraged, but not specifically prohibited; the appropriateness of use of such agents is left to physician discretion
• All concomitant medications must be recorded at baseline
• Patients on maintenance corticosteroids are ineligible with the exception of short term use (fewer than 5 days)
• Patients known to have congestive heart failure; patients with baseline requirement for oxygen; patients with serious concomitant illness that, in the opinion of the treating physician, will place patient at unreasonable risk from therapy on this protocol
• Patients with a history of unprovoked deep vein thrombosis (DVT) or pulmonary embolism (PE), unless patient is maintained on anticoagulation for the duration of the trial; while the exact definition of "provoked" is left to the treating physician, a DVT in the setting of pelvic surgery or trauma would be considered "provoked"
• Women of child-bearing potential must have a negative pregnancy test prior to treatment on study; breastfeeding should be discontinued if the mother is treated with temsirolimus
• Women of child-bearing potential and men must agree to use adequate contraception (barrier method of birth control or abstinence; oral contraceptives [also known as "the pill"] are not acceptable) prior to study entry and for the duration of stud
