Purpose: In this review, we discuss the plight of Alice, a patient with advanced nonsmall cell lung cancer (NSCLC) who struggles with taxane-related peripheral neuropathy (PN). Using this unique point of view helps us to appreciate the implications of PN on daily activities as well as the difficulty in decision-making regarding continuation of treatment. In addition, published reports of phase 3 trials are reviewed to identify the incidence and severity of chemotherapy-induced PN as well as the assessment tools used in these studies.
Methods: A literature review spanning the years 1998-2012 was performed. Phase 3 studies and a meta-analysis of taxane-based therapy in advanced NSCLC were selected for review for their findings regarding the incidence and severity of chemotherapy-induced PN.
Results: In total, 16 phase 3 studies and 1 meta-analysis were reviewed. Use of grading scales and PN assessment tools was inconsistent across the studies, and some studies did not report PN at all.
Conclusions: The true incidence and severity of chemotherapy-induced PN in clinical trials may be masked by nonstandardized reporting; thus, a more standardized approach to grading, assessing, and reporting PN in clinical trials is greatly needed to allow for appropriate comparisons across studies. Understanding chemotherapy-induced PN from the patient's perspective as well as the development of PN at the clinical trial level will help health care providers anticipate the development of PN and improve their ability to manage it.
