Zimmer, P., Trebing, S., Timmers-Trebing, U., Schenk, A., Paust, R., Bloch, W., . . . Baumann, F.T. (2017). Eight-week, multimodal exercise counteracts a progress of chemotherapy-induced peripheral neuropathy and improves balance and strength in metastasized colorectal cancer patients: A randomized controlled trial. Supportive Care in Cancer, 26, 615–624.
This study investigates the connection of providing an eight-week guided multimodal exercise class twice a week to patients with metastatic colorectal cancer in hopes of influencing their chemotherapy-induced peripheral neuropathy.
30 outpatients with metastatic colorectal cancer and with a history of chemotherapy treatment were recruited to participate in a randomized control trial. The intervention group participated in an eight-week supervised multimodal exercise class twice a week/60 min. This class included endurance, resistance, and balance training. The control group was given written recommendations to complete physical activity. Chemotherapy-induced peripheral neuropathy was measured using the FACT/COC-NTX questionnaire. Endurance capacity, strength, and balance were also measured at three separate intervals: before, after, and four weeks post-study.
Randomized control trial
The study showed significant improvement in neuropathic symptoms in the intervention group compared to worsening symptoms in the control group (p = 0.023). Increase of balance was noted between groups (p = 0.048) along with static balance (TOI, p = 0.022; NXT, p = 0.006). The intervention group noted an increase in strength from baseline: bench press (p = 0.006), leg press (p = 0.002), and lat pull down (p < 0.001)
The implementation of a multimodal, supervised exercise program showed significance in counteracting the neuropathic symptoms related to chemotherapy, increasing muscle strength and increasing balance in patients with metastatic colorectal cancer.
Patients at risk for chemotherapy-induced peripheral neuropathy (CINP) could benefit from a supervised multimodality exercise class to counteract the worsening effects of CINP. Providing your patients with written instruction for exercise might not be enough of an intervention to combat the worsening of this side effect.
