Lung carcinoma (LC) is the most common malignant tumor in clinical practice that seriously harms human health. Diabetes mellitus (DM) is a common chronic metabolic disorder, with type 2 DM (T2DM) being the most prevalent. The prevalence of DM complicated with LC is increasing worldwide.
Blood glucose (BG) fluctuation is definitely a factor affecting the chemotherapy efficacy and prognosis of patients with DM complicated with cancer. However, whether the BG level can be a predictor of chemotherapy efficacy in LC patients has rarely been studied, and epidemiological evidence is limited.
This study focuses on the influence of BG fluctuations on chemotherapy efficacy in T2DM + LC patients.
The clinical data of 60 T2DM + LC patients were retrospectively analyzed. All patients underwent chemotherapy and were grouped as a control group and an observation group based on their BG fluctuations, with 30 cases each. BG-related indices, tumor markers, serum inflammatory cytokines and adverse reactions were comparatively analyzed.
After chemotherapy, fasting BG and 2-h postprandial BG in the observation group were significantly higher than those in the control group. In addition, the observation group exhibited markedly higher mean amplitude of glycemic excursions, mean of daily differences, largest amplitude of glycemic excursions, and standard deviation of BG than the control group patients with high fluctuating blood glucose ranges have relatively weaker glycemic control and greater blood glucose fluctuations after chemotherapy. The observation group has higher levels of tumor markers and inflammatory indicators than the control group, as well as adverse event rate.
Large BG fluctuations can enhance the levels of tumor markers and inflammatory factors in T2DM + LC patients and inhibit chemotherapy efficacy, with low safety.
The control of BG fluctuations occupies an important position in T2DM + LC patients undergoing chemotherapy, which can affect the curative effect of chemotherapy.
