Purpose: Chemotherapy-induced peripheral neuropathy (CIPN) may necessitate chemotherapy dose reduction, delay, or discontinuation. This pilot study tested feasibility of patient enrollment, CIPN screening, and data collection in cancer patients for a future clinical study that will assess the safety and efficacy of an intervention that may prevent CIPN. Methods: This prospective, observational, single-center, pilot study included adults with newly diagnosed lymphoma or multiple myeloma receiving neurotoxic chemotherapy. Patients were enrolled between September 2016 and February 2017. The Functional Assessment of Cancer Therapy/Gynecologic Oncology Group-Neurotoxicity (FACT/GOG-Ntx) questionnaire was completed by patients at 3 time points: baseline, week 6, and week 12. The primary outcome was change in the neurotoxicity score between these time points. Results: Of 33 patients approached for consent, 28 (85%) provided consent and were enrolled. The FACT/GOG-Ntx questionnaire was completed by 28 (100%) at baseline, 25 (89%) at week 6, and 24 (86%) at week 12. Average (standard deviation) neurotoxicity scores were 36.5 (6.6) at baseline, 34.0 (8.3) at week 6, and 30.6 (7.6) at week 12. Neurotoxicity scores changed from baseline by − 2.7 points (95% CI − 5.5 to 0.1; p = 0.061) at week 6 and − 6.0 points (95% CI − 5.6 to − 0.8; p = 0.012) at week 12. Clinically meaningful declines (decrease of > 10% from baseline) in neurotoxicity score were detected in 36% (9 of 25) at week 6 and in 67% (16 of 24) at week 12. Conclusion: Sixty-seven percent of patients experienced clinically significant CIPN within 12 weeks of starting chemotherapy. Feasibility metrics for enrollment, consent, CIPN assessment, and follow-up were met.
