Summary

This trialstudies how antibiotics affect the microbes in the stomach/intestines before surgery for melanoma. It may help learn if changes in microbes affect surgery & cancer response.

Who is the study for?
This trial is for adults with early stage melanoma (stage I-II) who are scheduled for surgery to remove the cancer. Participants must not have used antibiotics in the last three months, be pregnant, or allergic to beta-lactam/cephalosporin antibiotics. They should not have infections or conditions that increase infection risk.
What is being tested?
The study is testing how taking the antibiotic cefazolin before surgery affects the microbiome of patients with stage I-II melanoma. Researchers want to see if changes in gut microbes influence recovery and response to cancer treatment.
What are the potential side effects?
Cefazolin may cause side effects like allergic reactions, diarrhea, nausea, rash, and possible changes in gut bacteria which could affect digestion and immunity.
