Abstract:

Background: Peripheral neuropathy (PN) occurs in NSCLC patients and may be due to various factors. One of the major factors is chemotherapy treatment. This study assessed the frequency and risk of PN among chemotherapy exposed NSCLC patients. Methods: This retrospective cohort study used the Optum claims in 2015-2017. The main inclusion criteria included: at least 2 diagnosis (Dx) claims for lung cancer; no other systemic cancer Dx within 6 months prior to the NSCLC Dx; at least one line of systemic anti-cancer treatment after the NSCLC Dx; presence of secondary metastatic disease. NSCLC was identified using a published algorithm. PN was identified by at least one claim with ICD-9/ICD-10 PN diagnosis code. Patients were followed from the earliest chemotherapy treatment date until a censoring event (PN Dx, end of enrollment, death, or end of study interval). Descriptive statistics were used to describe demographics; the Cox model and logistic regression were used to analyze risk associated with PN. Results: A total of 5082 patients were identified with an average age of 70.9 years (SD = 8.7) and 52% of male. Most common first line of treatment (LoT) was carboplatin + paclitaxel (31.9%); 32.7% of patients received a 2nd line, 7.6% received a 3rd line, and 1.7% received a 4th or higher line. 857 patients had PN during the follow-up period (16.9%). Median Charlson comorbidity index (CCI) was 1, and mean 1.7 (SD = 1.8). Patients with CCI of 4+ (716 patients) had nearly 60% elevated risk of PN as compared with CCI = 0. Patients with diabetes presented the OR (odds ratio) of 1.58; patients with a history of PN had a higher risk of PN after the initiation of chemotherapy (OR = 3.90). Compared with the PN risk during 1st LoT (reference), the OR of developing PN during 2nd and 3rd+ LoTs was elevated to 1.78 (95%CI 1.49-2.11; p < 0.0001) and 2.61 (95%CI 2.03-3.34; p < 0.0001), respectively. The most common type of PN was sensory neuropathy (33%), then polyneuritis (21%) and diabetic polyneuropathy (18%). Conclusions: PN is common in NSCLC patients. This analysis shows that the risk of PN in NSCLC patients increases significantly along increasing number of LoT. A history of PN and presence of diabetes play an important role as risk factors of PN during anti-cancer systemic treatment.
