We give our patients antibiotics in oncology far too easily, often without pause for thought on the benefits vs risks. Inappropriate use of antibiotics breeds multi drug resistance, causes adverse effects which can impact a patient’s quality of life, and this study shows can negatively impact on survival. Antibiotics destroy the gut microbiome leading to bacterial overgrowth of immunosuppressive organisms, causing excess wind and bloating, and as you can see from the meta analysis attached, potentially impacting survival in a negative way. If there is one message I have taken away from it is the importance of optimising the to ensure the most robust immuno surveillance and immune response to cancer neoantigens. We must think twice before “carpet bombing” our patients microbiome with unnecessary anti microbial therapy.
