An exercise oncology program improves sleep quality in head and neck cancer patients undergoing chemo-radiation therapy

A randomized controlled trial of 70 head and neck cancer patients found that a 7-week exercise oncology program (15-20 minutes of brisk walking and resistance training) significantly improved Pittsburgh Sleep Quality Index scores from 13.97 to 7.09, while the control group's scores worsened from 13.06 to 14.14 (both p < 0.001). Urinary melatonin levels increased in the exercise group but the between-group difference was not significant after adjusting for baseline values (p = 0.372).

An exercise oncology program improves sleep quality in head and neck cancer patients undergoing chemo-radiation therapy The current body of evidence comprises 1 study, including 1 randomized controlled trial. EvidenceHub rates the overall confidence at 42/100 (low).

The Claim

An exercise oncology program improves sleep quality in head and neck cancer patients undergoing chemo-radiation therapy

This conclusion is most relevant to: Head and neck cancer patients (stage III, IVa, or IVb) undergoing chemo-radiation therapy, aged 18 years or above, any gender, with ECOG score < 2.

What the Research Shows

The conclusion draws on 1 linked study. Highlights from the cited literature:

  • Efficacy of an exercise oncology program on sleep quality and circadian rhythm in head and neck cancer patients undergoing chemo-radiation therapy: a randomized controlled trial. (PeerJ, 2026) —

How It Works

The proposed biological pathway:

  • Exercise may enhance melatonin secretion
  • Improved circadian rhythm regulation
  • Reduced inflammation and stress
  • Result: Improved sleep quality

Who Might Benefit

Evidence fit by population:

  • Head and neck cancer patients (stage III, IVa, or IVb) undergoing chemo-radiation therapy, aged 18 years or above, any gender, with ECOG score < 2

Limitations & Caveats

Important context when interpreting this evidence:

  • Between-group difference in urinary melatonin was not statistically significant (p = 0.372), limiting support for circadian rhythm mechanism
  • Small sample size (n=70) and single-center design may limit generalizability

Frequently Asked Questions

What type of exercise was used in the program?

The program included 15-20 minutes of brisk walking (aerobic) and upper/lower limb resistance training.

How was sleep quality measured?

Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI), a validated self-report questionnaire.

Did the exercise program affect melatonin levels?

Urinary melatonin increased in the exercise group but the change was not statistically significant compared to the control group after adjusting for baseline values.

Who was eligible for this study?

Patients with stage III, IVa, or IVb head and neck cancer undergoing chemo-radiation, aged 18+, with ECOG score less than 2, and without severe orthopedic or neurological conditions.
