ABSTRACT
AIMS: Chemotherapy-induced peripheral neuropathy limits cancer survivors' compliance with chemotherapy and impaired function. This study aimed to examine separate impacts of clinician-assessed, patient-reported sensory and motor chemotherapy-induced peripheral neuropathy on physical/role function and functional interference in advanced colorectal cancer survivors receiving chemotherapy. METHODS: A cross-sectional, correlational design utilizing convenience sampling enrolled 75 stage III or IV colorectal cancer adults undergoing chemotherapy. Participants filled out the Patient Neurotoxicity Questionnaire, Identification Pain Questionnaire, and Peripheral Neuropathy Scale. Then, a trained research nurse conducted a brief neurological assessment using the Total Neuropathy Scale - clinical version. RESULTS: The prevalence of sensory and motor chemotherapy-induced peripheral neuropathy was from 34.7% to 54.7% and from 16.0% to 17.3%, respectively. Further, 20% of participants suffered from neuropathic pain. A low correlation between clinician-assessed and patient-reported chemotherapy-induced peripheral neuropathy was detected. The function was significantly impacted by patient-reported motor chemotherapy-induced peripheral neuropathy. CONCLUSIONS: This study was superior in utilizing the brief and valid patient-reported and clinician-assessed tools to measure sensory and motor chemotherapy-induced peripheral neuropathy. Moreover, the identification of patient-reported motor symptoms has the largest influence on function in advanced colorectal cancer survivors. Nurses may use the brief and easily administered tools in clinical settings for effective screening and early detection of motor and sensory chemotherapy-induced peripheral neuropathy to prevent functional decline in advanced colorectal cancer survivors. However, this study was still limited because of the cross-sectional design, small sample size, sample heterogeneity, and recruiting participants from only one medical center.

OBJECTIVES: To evaluate the feasibility of implementation of an extremity exercise program and to examine its preliminary effects in breast cancer survivors suffering from chemotherapy-induced peripheral neuropathy (CIPN). SAMPLE & SETTING: Thirteen breast cancer survivors from one hospital in northern Taiwan. Methods and Variables: A single group with repeated measures, and a quasi-experimental design. The intervention program was a four week, home-based extremity exercise program that was comprised of 10 skilled hand exercises and Buerger-Allen exercises. The Total Neuropathy Scale (clinical version), Functional Assessment of Cancer Therapy/Gynecologic Oncology Group, Neurotoxicity (13-Item Version), Identification Pain Questionnaire, and pain Visual Analogue Scale were used to measure CIPN before exercise (T1), during (T2~T4), and after exercise (T5). Qualitative data were also collected at each time point. Data were analyzed by using descriptive statistics, generalized estimating equations, and directed content analysis. RESULTS: None of the participants reported adverse events during the study period. The extremity exercise program significantly improved patient-reported CIPN after intervention at T4 or T5 but was insignificant on clinician-assessed CIPN. The qualitative data of participant experience indicated that this program is feasible and easy to follow. CONCLUSION: The extremity exercise program is feasible but needs to increase the sample size and prolong the intervention period for confirmation.
