Gut bacteria may supercharge lung cancer therapy

This study tests whether taking a daily probiotic (Lactobacillus rhamnosus LR607) for three months can make standard chemoimmunotherapy work better for people with stage IIB-IIIB non-small cell lung cancer before they have surgery. About 46 adults will take the probiotic alongside their cancer treatment and be monitored for tumor response, side effects, and changes in gut bacteria. The goal is to see if this combination can shrink tumors more effectively and improve surgical outcomes.
