PURPOSE: To date, the specific role of "in-field" crusting exudation on pain and on activity of daily living (ADL) in head and neck cancer (HNSCC) patients undergoing treatment with cetuximab and radiochemotherapy has been neglected. The purpose of the study was to evaluate the role of crusting exudation on the severity of pain and ADL METHODS: Thirty-seven of the 45 HNSCC patients enrolled in the alternating radiotherapy, chemotherapy, and cetuximab trial were evaluated in this study. The main radiodermatitis signs (the intensity of erythema, the extension of dry, and moist desquamation and of necrosis)--including crusting exudation severity--pain, ADL, and radiodermatitis scores were registered at least weekly during and after treatment. The correlation between crusting exudation and pain or ADL was evaluated. RESULTS: The "in-field" crusting exudation score seemed to have the strongest correlation with pain (Spearman's rho = 0.897; p < 0.001) and the most intense influence on it (Co-B = 0.715; 95% C.I. = 0.643-0.787). However, it seemed to have a weaker correlation with ADL than the other clinical radiodermatitis signs. CONCLUSIONS: Crusts have the strongest correlation with pain in patients with Cetuximab-related radiation dermatitis. Moreover, the presence of crusts can lead operators to misclassify dermatitis as score 4, causing unnecessary delays or interruptions in treatment.
