Diabetic patients with breast cancer receiving metformin and neoadjuvant chemotherapy have a higher pCR rate than do diabetics not receiving metformin. Additional studies to evaluate the potential of metformin as an antitumor agent are warranted.

Context The current state of palliative care in cancer centers is not known. Objective We conducted a survey to determine the availability and degree of integration of palliative care services, and to compare between National Cancer Institute (NCI) and non-NCI cancer centers in the United States. Design, Setting, and Participants Between June and October 2009, we surveyed both executives and palliative care clinical program leaders, where applicable, of 71 NCI cancer centers and a random sample of 71 non-NCI centers regarding their palliative care services. Executives were also asked about their attitudes toward palliative care. Main Outcome Measure Availability of palliative care services in the cancer center, defined as the presence of at least one palliative care physician. Results We sent 142 and 120 surveys to executives and program leaders, with response rates of 71% and 82%, respectively. NCI cancer centers were significantly more likely to have a palliative care program (50/51 (98%) vs. 39/50 (78%), P=0.002), at least one palliative care physician (46/51 (90%) vs. 28/50 (56%), P=0.04), an inpatient palliative care consultation team (47/51 (92%) vs. 28/50 (56%), P<0.001), and an outpatient palliative care clinic (30/51 (59%) vs. 11/50 (22%), P<0.001). Few centers had dedicated palliative care beds (23/101 (23%)) or an institution-operated hospice (37/101 (36%)). The median reported durations from referral to death were 7 (Q1–Q3 4–16), 7 (Q1–Q3 5–10), and 90 (Q1–Q3 30–120) days for inpatient consultation teams, inpatient units, and outpatient clinics, respectively. Research programs, palliative care fellowships, and mandatory rotations for oncology fellows were uncommon. Executives were supportive of stronger integration and increasing palliative care resources. Conclusion Most cancer centers reported a palliative care program, although the scope of services and the degree of integration varied widely. Further efforts to consolidate existing infrastructure and to integrate palliative care in cancer centers are warranted.

These findings provide evidence from a randomized controlled trial that a dietary intervention designed to elicit weight loss reduces overall inflammation in older, obese persons. Additional studies are needed to assess the effects of different modes and intensities of exercise on inflammation.
