Abstract
Background/aim: We previously reported that patients with metastatic colorectal cancer (mCRC) and baseline liver metastasis are at a higher risk of developing grade ≥2 overall skin toxicities when treated with anti-epidermal growth factor receptor (EGFR) monoclonal antibody. This study aimed to identify additional factors associated with skin toxicities induced by anti-EGFR treatment in patients with liver metastatic CRC.
Patients and methods: Patients with liver metastatic CRC who initially received anti-EGFR monoclonal antibody-containing treatment (n=77) were retrospectively assessed. The primary endpoint was to identify the factor(s) responsible for the development of grade ≥2 overall skin toxicities. Additionally, factors for grade ≥2 rash and paronychia were evaluated.
Results: The incidence of grade ≥2 overall skin symptoms, rash, and paronychia was 62.3%, 31.2%, and 28.6%, respectively. Multivariate Cox proportional hazard regression analyses revealed that age <65 years and anemia were independent baseline risk factors for grade ≥2 overall skin toxicities (adjusted hazard ratio 2.09, 95% confidence interval=1.10-3.97, p=0.02 for age; 2.36, 1.20-4.61, p=0.01 for anemia). In contrast, combination prophylaxis using systemic minocycline and corticosteroid ointment was a preventive factor (0.47, 0.25-0.88, p=0.02). Males and age <65 years were baseline risk factors for grade ≥2 rash, and combination prophylaxis was identified as a preventive factor. No factors were identified for paronychia.
Conclusion: Age <65 years and anemia were identified as independent baseline risk factors. Additionally, combination prophylaxis was found to be a preventive factor against anti-EGFR monoclonal antibody-induced grade ≥2 overall skin toxicities in patients with liver metastatic CRC.
