In palliative care, how can you differentiate diarrhea caused by infection from diarrhea related to cancer therapy?

Fever with leukocytosis and positive cultures point to an infectious cause. When diarrhea occurs in cancer patients, infection is a key consideration, and systemic signs like fever plus an elevated white blood cell count raise suspicion for an infectious process. Stool cultures (and specific tests for parasites or C. difficile) help identify the culprit and guide targeted treatment, while also triggering infection-control precautions if needed. Diarrhea from cancer therapy, by contrast, is often noninfectious and stems from mucosal injury to the gut caused by chemotherapy or other anticancer treatments. This type tends to be secretory or inflammatory due to damaged absorptive surfaces and rapidly dividing mucosa, and it may occur during or after treatment without fever or a positive infectious workup. In practice, a patient presenting with diarrhea in palliative care would be evaluated with a clinical assessment plus lab tests (complete blood count, electrolytes, stool studies, and possibly infection-specific tests) to distinguish infection from therapy-related causes, then management is guided accordingly—antibiotics and isolation for infection, or supportive care and treatment modification for therapy-related diarrhea.
