The LAR for Chemotherapy-Induced Diarrhea (LARCID) trial evaluated the efficacy and safety of long-acting release octreotide (octreotide LAR) for the prevention of CID in this population. Patients and Methods Patients with colorectal cancer starting adjuvant or first-line treatment with a chemotherapy combination containing fluorouracil, capecitabine, and/or irinotecan were randomly assigned to receive octreotide LAR 30 mg intramuscularly every 4 weeks (experimental arm) or the physician's treatment of choice in case of diarrhea (control arm). Results A total of 139 patients were randomly assigned, most of whom received fluorouracil- and oxaliplatin-containing chemotherapy regimens. The rate of diarrhea was 76.1% in the experimental group (n = 68) and 78.9% in the control group (n = 71). Treatment with octreotide LAR did not prevent or reduce the severity of CID. Treatment choices for diarrhea management included loperamide in the majority of patients. No benefit from octreotide LAR was identified in terms of need for diarrhea treatment, opioids, or intravenous hydration or in the rate of hospitalization or quality of life. Conclusion This study could not prove the efficacy of octreotide LAR in the prevention of CID.engrestrictedAccess2 different schedules1st-line treatmentrecommended guidelinesoral capecitabineirinotecanfluorouracilmulticenterloperamidetherapyleucovorinarticleCopyright BIOMED CENTRAL LTD10.1200/JCO.2013.50.8077Oncology1527-7755
