Abstract
Purpose
The prospective pilot study was designed to evaluate the preventive effects of amino-acid-rich elemental diet (ED), Elental®, on chemotherapy-induced oral mucositis in patients with colorectal cancer. The factors influencing its efficacy are also investigated.
Methods
A total of 22 eligible patients with colorectal cancer experiencing grade 1–3 oral mucositis during treatment with fluorouracil-based chemotherapy entered the current study. Their average age was 67 years. There were 10 male and 12 female. The PS was 0 in the majority of patients. Patients received two courses of the same chemotherapy regimen and Elental® concurrently after recovery to grade 0 or 1 oral mucositis.
Results
FOLFOX6 + bevacizumab in 8 patients, FOLFIRI + bevacizumab in 8 patients, FOLFIRI + panitumumab in 1 patient, FOLFIRI in 1 patient, XELOX + bevacizumab in 2 patients, and S-1 + cetuximab in 2 patients were used as first-line (16 cases) or as second-line (6 cases) chemotherapy. Dose reduction of 5-fluorouracil (5-FU) or oral fluoropyrimidine was performed in the 2 patients achieving grade 3 oral mucositis and in the 3 patients achieving grade 2 oral mucositis. The maximum grade of oral mucositis decreased in 18 of the 22 patients during the first treatment course with Elental® (p = 0.0002) and in 20 of the 22 patients in the second course (p < 0.0001). Multivariate analyses found that the dose reduction in 5-FU or oral fluoropyrimidine, ED intake, and the prior administration of ED were each a significant factor for the preventive efficacy on oral mucositis.
Conclusion
The amino-acid-rich elemental diet Elental® may be useful as a countermeasure for 5-FU-based chemotherapy-induced oral mucositis in patients with colorectal cancer.
