Association Between Physical Activity Levels and Chemotherapy-Induced Peripheral Neuropathy Severity in Cancer...

Area of Science:

• Oncology
• Neurology
• Rehabilitation Medicine

Background:

• Chemotherapy-induced peripheral neuropathy (CIPN) is a common and often dose-limiting side effect of cancer treatment.
• CIPN can significantly impact a survivor's quality of life, leading to sensory deficits, pain, and balance problems.
• The role of exercise in managing CIPN remains an area of active investigation.

Purpose of the Study:

• To investigate the association between different levels of physical activity and the characteristics of CIPN in cancer survivors.
• To compare demographic, clinical, and subjective/objective measures of CIPN across exercise groups.

Main Methods:

• A cohort of 290 cancer survivors was categorized into no exercise (NoEx), less exercise (LessEx), and recommended exercise (RecEx) groups based on weekly physical activity.
• Survivors completed self-report questionnaires assessing neuropathy symptoms and underwent sensory and balance testing.
• Demographic and clinical data, including comorbidity and functional status, were collected.

Main Results:

• The NoEx group exhibited poorer functional status, lower income, less education, and higher comorbidity compared to the RecEx group.
• No significant differences were observed among the exercise groups regarding CIPN duration, pain intensity, or specific sensory changes (light touch, cold, pain).
• While exercise levels were linked to demographic and clinical factors, direct impact on specific CIPN measures was not evident in this study.

Conclusions:

• Walking can be recommended as a beneficial activity for cancer survivors experiencing CIPN.
• Referral to physical therapy may be a valuable intervention for managing CIPN symptoms.
• Further research is warranted to elucidate the precise mechanisms and optimal exercise regimens for CIPN management.
