151 Background: CIN is the most prevalent neurologic complication of cancer treatment. Inter-individual variability exists in survivors’ reports of the factors that aggravate CIN in their feet. The purpose of this study was to identify groups of survivors with CIN in their feet based on distinct aggravating factors and evaluate for differences in demographic, clinical, symptom characteristics and quality of life (QOL) based on group membership. Methods: Cancer survivors (n = 403) who received a platinum and/or a taxane and rated their altered sensation/pain in their feet at > 3 on 0-10 scale were enrolled and completed study questionnaires, including a list of 22 factors that could make pain worse. Medical records were reviewed and sensory and motor tests were done. Latent class analysis was used to identify groups of survivors based on the occurrence rates for aggravating factors. Differences among the groups were evaluated using parametric and nonparametric statistics. Results: Three groups were identified based on occurrence rates for aggravating factors in the feet (i.e., Activity and Temperature (40.2%), Activity (25.8%), Few Factors (34.0%)). No differences were found among the groups in demographic characteristics, or sensory (light touch, temperature, pain, vibration) and motor (Timed Up and Go, Fullerton Assessment of Balance) tests. Compared to the Few Factors group, the other two groups had higher BMI, worse foot pain, poorer functional status and sleep, more depressive symptoms, and lower QOL. Survivors who received a platinum compound were more likely to be in the Activity and Temperature group. Those that received a taxane compound were more likely to be in the Few Factors or Activity groups. Conclusions: Survivors who reported a higher occurrence of aggravating factors had a higher symptom burden and poorer QOL. Objective measures did not differ among the groups. Aggravating factors associated with the CTX received supports previous work in that the survivors who received platinum drugs noted cold temperatures aggravated their CIN. Findings suggest that subgroups of survivors can be identified based on their reports of CIN aggravating factors.
