Physical Activity During Radiation Therapy for Lung Cancer

NCT07380815 | Not Yet Recruiting

• 1 other identifier: APART-LUNG
• Study Type: observational
• Target: 20
• Locations: 0 countries
• Sites: N/A

Brief Summary

The primary objective of this trial is to evaluate patterns of physical activity during radiation therapy for lung cancer and to estimate the within-patient change in physical activity between Week 1 and Week 5 of radiation therapy, measured by smart phone-recorded step counts normalized for device carrying time. The trial is exploratory in nature with the aim to generate scientific hypotheses to be investigated in future clinical trials.

Outcome Measures

Primary Outcomes (1)

• Mean number of steps per week during week 1 and week 5 of radiation therapy for lung cancer

  The primary endpoint is to assess the within-patient difference in weekly average steps per wear-hour of the smart phone (Week 5 minus Week 1 of radiation therapy). Any type of smart phone is allowed, as long as it has a step counter.

  through study completion, 5 weeks

Secondary Outcomes (1)

• Wear-time of the smart phone

  through study completion, 5 weeks

Study Arms (1)

Patients with steps counted by their smart phone

The purpose is to obtain a patient's mean number of steps per week during week 1 and week 5 of a radiation therapy course for lung cancer directly from the patient's smart phone which has a step counter.
