Association between dermatologic adverse events and quality of life in lung cancer patients treated with epidermal growth factor receptor-tyrosine kinase inhibitors

Abstract

Purpose: Epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) are frequently associated with dermatologic adverse events (dAEs), having great impacts on patients' health-related quality of life (HRQoL) and treatment adherence. We aimed to examine the association between various dAEs and HRQoL in patients treated with EGFR-TKI therapy.

Methods: This was a cross-sectional study including 132 non-small-cell lung cancer (NSCLC) patients treated with gefitinib, erlotinib, afatinib, or osimertinib in Taiwan. The severity level of dAEs was graded by NCI-CTCAE v4.03 and PRO-CTCAE ITEMS v1.0. All participants answered the Functional Assessment of Cancer Therapy-Epidermal Growth Factor Receptor Inhibitors (FACT-EGFRI-18) HRQoL questionnaire.

Results: The clinician-reported severity of pruritus, photosensitivity, alopecia, and Karnofsky performance status was associated with HRQoL (β = - 6.773, p = 0.046; β = - 5.250, p = 0.032; β = - 8.121, p = 0.001; β = 0.327, p = 0.002; respectively). The clinician-reported severity of all dAEs except paronychia had negative correlations with HRQoL. The symptom gradings of CTCAE and PRO-CTCAE had positive correlation.

Conclusions: The severity of pruritus, photosensitivity, and alopecia was associated with HRQoL of patients receiving EGFR-TKI therapy. Using patient-reported outcome measurements helps clinicians to capture the actual impact of symptoms on physical, social-emotional, and functional well-being.
