The Role of Coenzyme Q10 in the Prophylaxis of Oxaliplatin Induced Peripheral Neuropathy in Patients With Colorectal Cancer

Обзор

This study aims to evaluate the possible beneficial role of coenzyme Q10 against oxaliplatin-induced peripheral neuropathy in patients with colorectal cancer.

Подробное описание

Oxaliplatin (OXA), a third-generation platinum-based anticancer drug, has better efficacy and lower toxicity than cisplatin and carboplatin. Currently, OXA combined with 5-FU and leucovorin is the standard adjuvant chemotherapy regimen for colorectal cancer (CRC) and the first-line treatment for metastatic CRCs. The major side effects of OXA include peripheral neurotoxicity, myelosuppression, and diarrhea. These adverse effects may lead to treatment discontinuation and reduced compliance among CRC patients. Specifically, oxaliplatin-induced peripheral neuropathy (OIPN) is a dose-limiting toxicity associated with OXA.

The mechanisms involved in OIPN include functional abnormalities in voltage-gated K+ channels, with increased expression of pro-excitatory K+ channels such as hyperpolarization-activated channels. Abnormalities in Na+ currents have been detected in 78% of patients who later develop chronic OXA-induced neuropathy (Krishnan et al., 2005). Dysregulation of Ca2+ homeostasis has also been suggested as a key factor in OXA-associated nerve damage. In vivo studies indicate that oxaliplatin-induced cold allodynia enhances the sensitivity and expression of transient receptor potential A1 (TRPA1) and transient receptor potential cation channel subfamily M member 8 (TRPM8).

Several studies suggest a relationship between OXA-induced neuropathy and oxidative stress. Additional potential contributors to neuropathic pain include T-cells (Th17 and Th1) and inflammatory cytokines such as tumor necrosis factor-alpha (TNF-α). Clinical studies have demonstrated that elevated IL-6 levels correlate with painful chemotherapy-induced neuropathy, and patients receiving IL-6 neutralizing antibodies as part of their therapy report reduced neuropathic pain compared to those not receiving these antibodies.

Coenzyme Q10 (CoQ10) is an oil-soluble, vitamin-like substance primarily present in mitochondria. It possesses anti-inflammatory and antioxidant properties and has demonstrated neuroprotective effects in animal models of neurodegeneration by stimulating cell growth and inhibiting cell death. CoQ10 has been shown to protect against cisplatin-induced neurotoxicity in a rat model and to reduce paclitaxel-induced peripheral neuropathy in rodents. Additionally, CoQ10 exhibited a protective effect against vincristine-induced peripheral neuropathy in rats (Elshamy et al., 2022). The neuroprotective effects of CoQ10 have been attributed to its ability to mitigate oxidative stress and inflammation, evidenced by significant reductions in malondialdehyde (MDA), 8-hydroxyguanosine (8-OHdG), TNF-α, IL-1β, and nuclear factor kappa-B. CoQ10 has also been reported to lower serum neurofilament-light chain (NF-L), a recognized biomarker for multiple neurodegenerative diseases.

In diabetic patients with peripheral neuropathy, antioxidant and anti-inflammatory supplementation with CoQ10 has shown potential benefits. A study reported that administration of CoQ10 at a dose of 200 mg/day for 12 weeks in neuropathic diabetic patients improved total antioxidant capacity (TAC) and reduced high-sensitivity C-reactive protein (hsCRP).

To the best of the investigators' knowledge, no clinical trials have been conducted to evaluate CoQ10 as a prophylactic therapy against chemotherapy-induced neuropathy. This study aims to assess its potential role in preventing oxaliplatin-induced peripheral neuropathy.

Вмешательства

• Препарат Coenzyme Q10
  100 mg once daily starting after the first chemotherapy cycle. Patients will receive 12 cycles of the modified FOLFOX-6 regimen with Coenzyme Q10 (100 mg once daily in the morning), starting after the first chemotherapy cycle and continuing until the end of the 12th cycle. Based on McRae (2023), 200 mg/day for 12 weeks reduced TNF-α and IL-6; thus, 100 mg/day for 6 months was selected (one cycle every 2 weeks = 24 weeks). Supportive care: Includes a 5-HT3 antagonist for nausea prevention and pa
