Objective Impaired glucose tolerance and diabetes are risk factors for the development of uterine cancer. Although greater progression free survival among diabetic patients with ovarian and breast cancer using metformin have been reported, no studies have assessed the association of metformin use with survival in women with endometrial cancer (EC). Methods We conducted a single-institution retrospective cohort study of all patients treated for uterine cancer from January 1999 through December 2009. Demographic, medical, social, and survival data were abstracted from medical records and the national death registry. Overall survival (OS) was estimated using Kaplan-Meier methods. Cox models were utilized for multivariate analysis. All statistical tests were two-sided. Results Of 985 patients, 114 (12%) had diabetes and were treated with metformin, 136 (14%) were diabetic but did not use metformin, and 735 (74%) had not been diagnosed with diabetes. Greater OS was observed in diabetics with non-endometrioid EC who used metformin than in diabetic cases not using metformin and non-endometrioid EC cases without diabetes (log rank test (p=0.02)). This association remained significant (hazard ratio = 0.54, 95% CI: 0.30–0.97, p<0.04) after adjusting for age, clinical stage, grade, chemotherapy treatment, radiation treatment and presence of hyperlipidemia in multivariate analysis. No association between metformin use and OS in diabetics with endometrioid histology was observed. Conclusion Diabetic EC patients with non-endometrioid tumors who used metformin had lower risk of death than women with EC who did not use metformin. These data suggest that metformin might be useful as adjuvant therapy for non-endometrioid EC.

Objective Aggressive care interventions at the end of life (ACE) are reported metrics of sub-optimal quality of end of life care that are modifiable by palliative medicine consultation. Our objective was to evaluate the association of inpatient palliative medicine consultation with ACE scores and direct inpatient hospital costs of patients with gynecologic malignancies. Methods A retrospective review of medical records of the past 100 consecutive patients who died from their primary gynecologic malignancies at a single institution was performed. Timely palliative medicine consultation was defined as exposure to inpatient consultation ≥30 days before death. Metrics utilized to tabulate ACE scores were ICU admission, hospital admission, emergency room visit, death in an acute care setting, chemotherapy at the end of life, and hospice admission <3 days. Inpatient direct hospital costs were calculated for the last 30 days of life from accounting records. Data were analyzed using Fisher's Exact, Mann–Whitney U, Kaplan–Meier, and Student's T testing. Results 49% of patients had a palliative medicine consultation and 18% had timely consultation. Median ACE score for patients with timely palliative medicine consultation was 0 (range 0–3) versus 2 (range 0–6) p = 0.025 for patients with untimely/no consultation. Median inpatient direct costs for the last 30 days of life were lower for patients with timely consultation, $0 (range 0–28,019) versus untimely, $7729 (0–52,720), p = 0.01. Conclusions Timely palliative medicine consultation was associated with lower ACE scores and direct hospital costs. Prospective evaluation is needed to validate the impact of palliative medicine consultation on quality of life and healthcare costs.

Statin and aspirin use was associated with improved survival from nonendometrioid endometrial cancer.
