Abstract :

Statement of the Problem: Oxaliplatin is an essential drug in treatment of colorectal cancer. Peripheral sensory neuropathy is the most prominently reported adverse effect. No standard agent has been approved for prevention of this neuropathy. Purpose: This prospective controlled study was conducted to evaluate the role of metformin in prevention of oxaliplatininduced peripheral neuropathy. Methodology & Theoretical Orientation: From November 2014 to May 2016, 40 patients with colorectal cancer stage III were enrolled and randomly allocated to a control group received 12 cycles of FOLFOX-4 regimen and a metformin group received the same regimen plus metformin 500 mg three times daily. The metformin efficacy was evaluated using the brief pain inventory short form ‚??worst pain‚?Ě item, National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE version 4.0) and a12-item neurotoxicity questionnaire (Ntx-12) from the validated Functional Assessment of Cancer Therapy/Gynecologic Oncology Group. In addition to malondialdehyde, interleukin-6 and neurotensin serum levels assessment. Results: By the end of 12 cycles, the mean pain scores in metformin group were significantly lower than those of control group, (6.7 versus 7.3, P = 0.005). Ninety-five percent of patients in control group experienced grade 2 and 3 while 40% of metformin group remained in grade 1 and only 60% experienced grade 2 and 3, P = 0.002. Furthermore, metformin group showed significantly higher total scores of Ntx-12 questionnaire than control group (24.0 versus 19.2, P < 0.001). Mean serum levels of malondialdehyde and neurotensin were significantly lower in metformin group after 6 and 12 cycles. However, mean serum levels of interleukin-6 showed non-significant difference between the two groups. Conclusion & Significance: Our findings may suggest that metformin is a promising drug in protecting colorectal cancer patients against chronic oxaliplatin-induced peripheral sensory neuropathy.
