Aim:This case–control study examined the impact of diabetes mellitus (DM) on survival in lung cancer patients and lung cancer on glycemic control in DM.Materials & methods:Patients with a new lung cancer diagnosis and DM (n = 124) were matched to 124 lung cancer patients without DM. Laboratory results and DM and cancer therapies were obtained from electronic records.Results:Five-year overall survival for lung cancer patients with and without DM was 20 versus 29% (p = .12). Glycemic control among DM patients did not change significantly with time.Conclusion:DM does not cause adverse impact on lung cancer survival. Lung cancer does not affect glycemic control.

Aim:We aimed to determine the effect of diabetes mellitus (DM) on survival in pancreatic cancer and effects of pancreatic cancer on glycemic control in DM.Materials & methods:Patients with pancreatic cancer from 2007 to 2015, with and without DM, were matched 1:1. We compared characteristics between the groups and assessed 2-year survival with Kaplan–Meier analysis.Results:In patients with DM, hemoglobin A1c decreased significantly over time (p = 0.01). In survival analysis, 2-year overall survival estimates were 15% (95% CI: 8–24%) for DM patients versus 26% (95% CI: 17–36%) for non-DM patients (p = 0.55). The hazard ratio for matched pairs was 1.15 (95% CI: 0.75–1.77; p = 0.51).Conclusion:DM did not decrease survival in pancreatic cancer. Pancreatic cancer did not affect glycemic control.

The impact of diabetes mellitus (DM) on survival in patients with colorectal cancer and the impact of colorectal cancer on glycemic control were examined. Materials & methods: Patients with colorectal cancer with and without DM were matched 1:1 (2007-2015). Characteristics were compared between the two groups and survival assessed with the Kaplan-Meier method. Mixed models compared hemoglobin A 1c and glucose levels over time. Results: In both groups, glucose values decreased during the year following cancer diagnosis (p < 0.001). 5-year overall survival was 56% (95% CI: 42-68%) for DM patients versus 57% (95% CI: 43-69%) for non-DM patients (p = 0.62). Conclusion: DM did not adversely impact survival of patients with colorectal cancer. Colorectal cancer did not affect glycemic control.
