Gastroparesis as a significant gastrointestinal adverse event during intensive chemotherapy for solid cancer

Abstract

Proper management of chemotherapy-related gastrointestinal toxicities is essential to maximize therapeutic outcome for malignancies. Gastroparesis is characterized by delayed gastric emptying without gastrointestinal obstruction. Although it has not been well recognized as a complication of chemotherapy for solid malignancies, we here report a case of gastroparesis apparently due to neurotoxicity of high-intensity taxane- and platinum-based chemotherapy for a solid tumor. The patient experienced late-onset gastric dysmotility as evidenced by an abnormally dilated stomach even after cessation of feeding for several days. The gastroparesis was successfully controlled with a 5-HT4 receptor agonist, resulting in recovery of gastric motility and allowing completion of curative anticancer treatment. Despite its rarity in patients with solid cancers, gastroparesis should be recognized as a potential cause of persistent upper abdominal symptoms during neurotoxic chemotherapy in such individuals, given that a delay in its management may be detrimental to survival outcome.
