Summary

Second malignant neoplasms and cardiac late effects are primary drivers of serious non-recurrence morbidity and mortality in long term childhood cancer survivors. Cardiac late effects have been most prominently associated with exposure to high doses of anthracyclines or chest radiation. While increased recognition of late effects has resulted in risk-targeted therapy and reductions in use of high dose radiation and anthracyclines for many patients, these cardiotoxic exposures continue to be essential components of curative childhood cancer therapy. In addition, as survivors age they are increasingly susceptible to other general risk factors for cardiovascular disease recognized in the general population, such as hypertension, obesity, dyslipidemia, and diabetes.

This study will evaluate a high blood pressure monitor (HBPM)-based intervention for the early detection of pre-hypertension and prevention of clinical hypertension in survivors of childhood cancer. Eligible and consenting participants will be randomized into one of three groups:

GROUP 1: Instructed to measure blood pressure (BP) every day for 3 months. GROUP 2: Instructed to measure BP for 7 consecutive days once a month, for 3 months.

GROUP 3: Instructed to measure blood pressure for 3 consecutive days each month, for 3 months.

The randomization to the above groups will be done using sequential assignment of newly recruited participants based on a randomly ordered list.

PRIMARY OBJECTIVE:

* Evaluate the feasibility of High Blood Pressure Monitoring (HBPM) for three consecutive months using a remote blood pressure device provided to participants of the St. Jude Lifetime cohort (SJLIFE) protocol.

SECONDARY OBJECTIVES:

* Assess compliance with use of HBPM by measurement frequency, evaluating overall and defined minimum use in each of the three different groups.
* Assess compliance with use of HBPM by cell phone status, evaluating those with and without a personal cell phone capable of connecting directly to the home blood pressure monitoring device via Wi-Fi or Bluetooth network.

Interventions

DEVICE

iHealth Wireless Blood Pressure Monitor

Participants will be provided with an iHealth Wireless Blood Pressure (BP) Monitor and instructions for proper use (based on a standard protocol). The iHealth device pairs easily with a cell phone or other mobile device equipped with the iHealth app (freely available on app stores for both Apple and Android devices). Participants place the cuff on their arm and press start on their mobile device. The device measures BP using the oscillometric method and automatically downloads measurements and timing to a cloud-based server. Participants will be educated that individual BP readings can be highly variable and that any one high or low reading has little or no significance. They will also be encouraged not to measure their blood pressure more than twice in the morning and twice in the evening.
