Which of the following is NOT listed as a common gastrointestinal toxicity in the first 2-3 weeks after stem cell transplant?

• A. Mucositis
• B. Nausea/vomiting
• C. Delayed gastric emptying
• D. Diarrhea

Answer: (A)

The main idea here is how post-transplant toxicities are categorized. After stem cell transplant, the early period is dominated by mucosal injury from conditioning and by GI symptoms, but many checklists separate oral mucosal issues from “gastrointestinal toxicity.” Nausea and vomiting, as well as diarrhea, are classic GI toxicities commonly listed in the first couple of weeks. Delayed gastric emptying can occur as a motility issue, though it’s not always highlighted as a primary early GI toxicity. Mucositis, while very common due to conditioning, is typically described as an oral (mucosal) complication rather than a GI toxicity category in some exams. Therefore, mucositis is not listed among the common GI toxicities in the first 2-3 weeks after transplant, making it the best answer in this context.
