Do immersive nature-based virtual reality or a matched relaxation video reduce symptoms during early chemotherapy cycles for lung cancer?

Evidence at a glance

  • Evidence label: Three-arm randomized trial; small acute symptom effects, no quality-of-life benefit
  • Benefit: Both formats improved several symptoms and distress during the sessions; the extra benefit of immersive VR over ordinary video was small.
  • Certainty: Moderate for short-lived within-session symptom changes; insufficient for durable quality of life or treatment outcomes.
  • Risk: Mild headache or dizziness occurred with VR and mild sadness with video; transient cybersickness may have been under-recorded.

What was studied

A prospective three-arm trial randomized 315 adults receiving lung-cancer chemotherapy to two 20-minute sessions of immersive nature-themed VR, theme-matched relaxation video on a standard screen, or routine care during the first two chemotherapy cycles.

What the evidence found

Compared with routine care, within-session well-being improved by 1.26 points with VR (95% CI 0.98 to 1.53) and 0.76 with video (0.49 to 1.03). Distress improved by 1.04 with VR and 0.73 with video. VR exceeded video by only 0.50 points for well-being, 0.47 for tiredness and 0.31 for distress; these symptom differences were below the prespecified minimal clinically important difference. Nausea, appetite and global quality of life did not improve.

How to interpret it

The intervention was brief, unblinded and assessed immediate state symptoms. Only 210 participants completed all four session assessments. The trial does not show durable benefit, equivalence between formats, lower chemotherapy toxicity or better cancer control.

These outcomes concern symptoms, distress, sleep or supportive care. They do not establish tumor response, delayed recurrence, progression-free survival or longer overall survival.

Practical safety context

One of 106 VR participants reported mild headache and one mild dizziness; one of 104 video participants reported mild sadness. No serious intervention-related event occurred. Headsets may be unsuitable with severe vertigo, uncontrolled seizures, visual or balance problems, delirium, infection-control constraints or distress triggered by immersive content.

Questions for the care team

  • Would a simple relaxation video be more practical than a headset for me?
  • Could dizziness, neuropathy, vision problems or seizure risk make VR unsafe?
  • How will the team distinguish temporary distraction from a symptom that needs treatment?

Funding and conflicts

The investigators reported no external funding and no conflicts of interest.
