Development and consensus process for a clinical pathway for the assessment and management of chemotherapy-induced peripheral neuropathy.

BACKGROUND: Cancer patients treated with neurotoxic chemotherapy are at risk of developing neurological symptoms that can impact functional capacity and quality of life. However, there are no standardised pathways to assess and manage chemotherapy-induced peripheral neurotoxicity (CIPN). This study aimed to determine consensus on statements regarding a CIPN assessment and management clinical pathway. METHODS: A CIPN clinical pathway (CIPN-path) was developed and reviewed by an expert multi-disciplinary panel and consumers. Agreement with 18 statements regarding four content themes (pretreatment review, screening and assessment, management and referral, and CIPN-path feasibility) were assessed by 70 Australian respondents (68 health professionals, 2 consumers), using a 2-stage Delphi survey process to reach consensus. Respondents rated statements using a 5-point Likert scale to determine the level of agreement, with consensus defined as ≥ 80% of respondents agreeing with each statement. RESULTS: The consensus was reached for 14 of 18 items after stage 1 and all items after stage 2. Feedback was obtained for all items to refine the CIPN-path. There was an agreement on important characteristics of the CIPN-path, including pretreatment screening, regular patient-reported assessment, and a stepped-care approach to investigating and managing symptom burden. There was a lack of agreement on who should oversee CIPN assessment, which may differ according to the structure and resources of each site. CONCLUSIONS: There was an overall agreement concerning the CIPN-path to assess and manage CIPN, which may be adapted accordingly to the resources of each clinic. The CIPN-path may assist teams across different health services in identifying CIPN symptoms, aiding decision-making, and reducing morbidity from CIPN.

Chemotherapy-Induced Peripheral Neurotoxicity in Cancer Survivors: Predictors of Long-Term Patient Outcomes.

BACKGROUND: Chemotherapy-induced peripheral neurotoxicity (CIPN) is a major adverse effect of cancer treatment. However, its impact remains poorly understood. This study aimed to investigate the impact associated with CIPN on the lives of cancer survivors. PATIENTS AND METHODS: A volunteer sample of 986 individuals who had received neurotoxic chemotherapy completed an anonymous, cross-sectional survey. Outcomes assessed included CIPN symptoms, pain, neuropathic pain, quality of life (QoL), physical activity, and comorbid health conditions via the Self-Administered Comorbidity Questionnaire. RESULTS: Respondents had a mean age of 58 years (SD, 10.7), and 83.2% were female. Most were treated for breast (58.9%) or colorectal cancer (13.5%); had received docetaxel (32.7%), paclitaxel (31.6%), or oxaliplatin (12.5%); and had completed treatment 3.6 ± 3.5 years previously. We found that 76.5% of respondents reported current CIPN. Respondents reporting severe CIPN had poorer QoL, more comorbidities, and higher body mass index, and more often received multiple neurotoxic chemotherapies than those with mild CIPN. Respondents who completed the survey ≤1 year after completing chemotherapy did not differ in reported CIPN or pain compared with respondents who completed chemotherapy ≥6 years earlier. However, respondents who completed chemotherapy ≥6 years earlier reported better QoL. Multivariable linear regression analyses revealed predictors of CIPN severity as follows: F(7, 874) = 64.67; P<.001; R2 = 0.34, including pain (ß = -0.36; P<.001), burning pain (ß = 0.25; P<.001), sex (male sex associated with greater CIPN: ß = 0.14; P<.001), years since completing chemotherapy (shorter time associated with greater CIPN; ß = -0.10; P<.001), age (ß = 0.80; P=.006), number of comorbid conditions (ß = 0.07; P=.02), and body mass index (ß = 0.07; P=.02). CONCLUSIONS: Respondents with a high CIPN symptom burden experienced poorer general health and QoL. Improvements in CIPN may be more likely soon after treatment. However, improvements in QoL may occur over time in those with chronic symptoms. CIPN seems to have lasting impacts on cancer survivors, and understanding risk factors is important to enable the design of further preventive and therapeutic management strategies.
