Official title
Evaluating the Impact of Perioperative Antibiotic Prophylaxis on the Microbiome in Patients With Cutaneous Malignancy
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This phase I trial investigates the impact of cefazolin before surgery on the microbiome in patients with stage I-II melanoma. Antibiotics, such as cefazolin, given at the time of surgery may cause a significant change in the microbes (like bacteria and viruses) found in the stomach and intestines. This trial may help researchers learn if any changes in microbes affect the body's ability to respond to surgery and cancer.
