Chemotherapy-induced peripheral neuropathy—patient-reported outcomes compared with NCI-CTCAE grade

Background Patient-reported outcomes (PRO) are becoming increasingly recognised as essential to comprehensively collect chemotherapy-induced peripheral neuropathy (CIPN) symptom information. Materials and methods This study aimed to evaluate the utility and feasibility of CIPN PRO assessment tools in a real-world clinical setting through investigation of the correlation of PRO with NCI-CTCAE assessments particularly in relation to cumulative dose of chemotherapy. Patients receiving oxaliplatin or paclitaxel chemotherapy in Sydney, Australia, completed a questionnaire containing standardised CIPN PRO assessments (EORTC CIPN-20, PRO-CTCAE) via tablet device. PRO assessment scores were correlated with NCI-CTCAE grade determined by nursing assessment and analysed with respect to cumulative dose of chemotherapy. Results There were 87 patients who completed a total of 145 questionnaires, 68 in patients receiving oxaliplatin and 77 in patients receiving paclitaxel. CIPN PRO scores were associated with NCI-CTCAE grade, for EORTC CIPN-20 ( r 2 = 0.19, p
