Effects of Probiotics on the Gut Microbiome and Immune System in Operable Stage I-III Breast or Lung Cancer

Anatomic Stage III Breast Cancer AJCC v8 Clinical Trial

Official title:
Engineering Gut Microbiome to Target Cancer-Immune Microenvironment in Breast and Lung Cancer

Clinical Trial Summary

This clinical trial evaluates whether engineering gut microbiome using probiotics will alter the body's immune system to react to stage I-III breast or lung cancers that can be removed by surgery (operable). Having diverse species of bacteria inside the bowel may help improve the immune system, particularly the ability of the immune system to recognize cancer. Taking probiotics may change the diversity and make up of the bacteria in the bowels, and change how the immune system reacts to breast or lung cancer.

Clinical Trial Description

PRIMARY OBJECTIVES: I. To conduct a pilot study of probiotics prior to surgery in operable breast and lung cancer patients. II. To evaluate systemic and intratumoral immunomodulatory effects of probiotics in operable breast and lung cancer patients. OUTLINE: Patients undergo collection of blood samples at baseline and time of surgery, and collection of stool samples at baseline and after completion of probiotic regimen. Patients receive probiotics orally (PO) once on day 1, and then twice daily (BID) or three times daily (TID) for 2-4 weeks before standard of care surgery. Patients also undergo collection of tissue samples during standard of care surgery. ;
