Oral compound probiotic supplements can improve the quality of life for patients with lung cancer during chemotherapy: A randomized placebo‐controlled study.

Background: Chemotherapy is an important approach for lung cancer patients. The study was designed to evaluate the feasibility of the compound probiotic supplements in improving the quality of life for lung cancer patients undergoing chemotherapy. Methods: This randomized, double‐blind, placebo‐controlled trial enrolled chemotherapy‐naive patients with lung cancer who were scheduled to receive platinum‐based doublet chemotherapy. All eligible patients were randomly administered (1:1) compound probiotic supplements (group BP‐1) or placebo (group C) for two chemotherapy cycles. The EORTC QLQ C30 questionnaire scores were evaluated before the first, second, and third cycles of chemotherapy. The primary endpoint was the difference in the EROTC QLQ C30 questionnaire score between the two groups after two cycles of chemotherapy. Results: A total of 110 patients were recruited from March 2021 to January 2022. After undergoing two cycles of chemotherapy, group BP‐1 were significantly better in various dimensions of the overall quality of life, role function, nausea and vomiting, appetite loss, constipation, and diarrhea relative to group C (76.90 ± 18.31 vs. 58.89 ± 17.17; 93.33 ± 11.58 vs. 85.93 ± 15.06; 0.00 ± 0.00 vs. 27.04 ± 29.15; 6.67 ± 13.53 vs. 22.22 ± 18.80; 0.95 ± 5.63 vs. 28.15 ± 22.42; 2.86 ± 9.47 vs. 15.56 ± 16.82; p < 0.05, respectively). The incidence of nausea and vomiting, appetite loss, constipation, and diarrhea in group BP‐1 was significantly lower than in group C (0% vs. 71.43%, 16.67% vs. 57.14%, 2.38% vs. 63.27%, and 7.14% vs. 42.86%, respectively, p < 0.001). Conclusions: Compound probiotic supplements can improve the quality of life and relieve chemotherapy‐related gastrointestinal side effects for lung cancer patients receiving platinum‐based doublet chemotherapy.
