EGFRI-associated health-related quality of life by severity of skin toxicity in metastatic colorectal cancer patients receiving epidermal growth factor receptor inhibitor target therapy.

PURPOSE: The purposes of this study were to assess the levels of symptom distress, body image, and epidermal growth factor receptor inhibitors (EGFRI)-associated health-related quality of life (QoL); identify the factors related to EGFRI-associated health-related QoL; and examine the differences in EGFRI-associated health-related QoL by grade of skin toxicity in mCRC patients receiving target therapy.

METHODS: This cross-sectional study examined mCRC patients who received cetuximab-based target therapy from the oncology and CRC inpatient and outpatient departments of a medical center in northern Taiwan. Structured questionnaires were used to measure patients' symptom distress, body image, and EGFRI-associated health-related QoL.

RESULTS: Of the 111 mCRC patients studied, 79.2% reported acneiform eruption and 52.2% reported paronychia. The most common symptoms were dry skin and itching. Poor EGFRI-associated health-related QoL was associated with more symptom distress, more negative body image, a higher cumulative dose of target therapy, and being married; these factors explained 66.6% of the variance in EGFRI-associated health-related QoL.

CONCLUSION: Patient-specific skin care and emotional support are needed to relieve distressful dermatological symptoms and emotional distress during and post-treatment for mCRC.
