Relationship of sensory symptoms and motor function in patients with chemotherapy-induced peripheral neuropathy (CIPN) utilizing the EORTC QLQ CIPN20: NCCTG study N06CA

9587 Background: CIPN is characterized by adjectives not covered directly by most common measures of pain and functional limitations. Possible descriptors include numbness, tingling and shooting/burning pain. A prospective neuropathy treatment trial provided data to explore the relationship between self-reported aspects of this symptom. Methods: Baseline EORTC QLQ CIPN20 data and NCI CTCAE V3.0 (CTC)neuropathy grade (I-IV) were provided for all patients on trial. Spearman correlation coefficients and Kappa's coefficients of agreement were calculated between individual items and subscales of the CIPN20 as well as the CTC neuropathy scale. Simple regression models were applied to examine the association between the sensory symptoms and motor function in the fingers/hands (F/H). 200 patients provided 80% power to detect a correlation coefficient of 0.20 with a 5% Type I error. Results: A majority of patients reported “quite a bit” to “very much” numbness (57%) or tingling (62%) in F/H compared to “a little” ...
