Abstract

BackgroundCancer patients who receive immunosuppressive therapy are vulnerable to infections due to their compromised immune systems. Therefore, research in promoting the prudent use of antibiotics in this population is essential to optimise patient outcomes and reduce resistance development. The pu...
