Brief Summary:


Many digital devices, such as smartphones and activity monitors, have sensors to collect and track health data. Researchers believe these devices may be able to transform the quality of clinical research and healthcare. They believe they may be able to help assess the symptoms, response to therapy, and quality of life of people with cancer.


To collect data from people with cancer using an Apple iPhone alone or together with an Apple Watch in order to assess their symptoms and activity levels.


People ages 18 years and over who have cancer and receiving treatment for their cancer in another NIH protocol


Participants will be screened with their medical records.

Participants will have a baseline visit. They will have visits every 2 4 weeks based on the treatment protocol in which they are co-enrolled. Then they will have a follow-up visit 4 months after the baseline visit. Visits include:

Medical history

Physical exam

Karnofsky Performance Scale/Eastern Cooperative Oncology Group performance status to see how their disease affects daily activities

The study team will use an iPhone to collect data. This includes a 6-minute walk test and tests of hearing, reaction time, and cognitive status.


If participants have an iPhone, an Apple Watch will be provided to them after training at the baseline visit. Continuous measurement of their activity will be recorded by the watch between 2 visits. They will wear the watch while they are on study. They will wear the watch while it is not being charged. They should charge the watch at night time. They will have the watch for 4 months.

1/Cohort 1
Participants with a diagnosis of cancer who are under active treatment on a protocol at NIH

Primary Outcome Measures :
  1. Outcomes from: PRO-CTCAE, Neuro-QOL, Numeric Rating Scale for Pain, 6-Minute Walking Test, Stroop Test, and Normalized Reaction Time Tests [ Time Frame: 4 months ]
    Percentage of patients successfully assessed for fatigue, reaction time, and cognitive status using an iPhone and Apple Watch.

Secondary Outcome Measures :
  1. Correlation between biometric monitoring system measures of activity and function with KPS, ECOG performance status and Neuro-QOL [ Time Frame: 4 months ]
  2. Association of patient reported outcomes, including fatigue and ability to participate in social role and activities questions, with iPhone tests that assess mobility, fatigability and cognitive function [ Time Frame: 4 months ]
  3. Evaluation of iPhone based tests of cognitive functioning and reaction time for reliability and validity [ Time Frame: 4 months ]
