NCT04857697

Brief 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.

Outcome Measures

Primary Outcomes (3)

  • Length and adherence of probiotics

    Will be collected via study diaries.

    Up to 4 weeks

  • Percentage of CD8+, CD4+, and T-reg cells

    Baseline up to 4 weeks

  • Cytokine counts

    Baseline up to 4 weeks

Study Arms (1)

Supportive care (biospecimen collection, probiotic)

EXPERIMENTAL

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 PO once on day 1, and then BID or TID for 2-4 weeks before standard of care surgery. Patients also undergo collection of tissue samples during standard of care surgery.
