Popis: Irinotecan, a topoisomerase I inhibitor, is commonly used in the treatment of advanced colorectal cancer. Its adverse effects include delay diarrhea, severe myelosuppression, and cholinergic-like symptoms. Though 2 cases of irinotecan-induced muscle twitching were reported but the successful treatment of this adverse event still not shown. We present a 24-year-old female patient with advanced colorectal cancer received bevacizumab and FOLFIRI (irinotecan + calcium leucovorin + 5-fluorouracil) treatment. Her right pectoralis major muscle presented with involuntary muscle twitching during the infusion of irinotecan at the sixth cycle of chemotherapy. The muscle twitching was slowly dissipated about 4 hours after the halted of irinotecan infusion. Then lorazepam 2 mg iv was injected before administration of irinotecan in an attempt to prevent the muscle twitching in the seventh cycle of chemotherapy. The patient did not report further muscle twitching. After that, lorazepam was routine administered before each cycle of FOLFIRI regiment. No any muscle twitching was observed after the use of lorazepam. This case provides valuable insight that muscle twitching can occur as rare irinotecan-related adverse effect. Benzodiazepine agonists, such as lorazepam, is the potential treatment of choice.
