Home-based cardio-oncology rehabilitation using a telerehabilitation platform in hematological cancer survivors: a feasibility study

Purpose Cardiovascular disease is a competing mortality cause in hematological cancer survivors due to toxic oncological treatment, accumulation of risk factors, and decline of cardiorespiratory fitness.

Cardio-oncology rehabilitation (CORE) is an emerging treatment model to optimize the prognosis of hematological cancer patients and survivors; however, its accessibility during the COVID-19 pandemic is poor.

The study aimed to evaluate the feasibility, safety, and effect of a 12-week home-based CORE intervention in telerehabilitation approach among hematological cancer survivors.

Methods A prospective single-arm interventional study was conducted at a faculty hospital in Brno, Czech Republic.

This study provided 12 weeks of the home-based CORE using a telerehabilitation approach that allows remote supervision by a clinician from a medical facility.

The telerehabilitation approach consists of three components: a heart rate sensor (PolarM430, Kempele, Finland), a web platform compatible with the sensor, and telesupervising via telephone call (1 call per week).

To improve adherence, a physiotherapist called participants to assess or address adverse effects, exercise feedback, and participant-related concerns.

The anthropometry, body composition, and cardiorespiratory fitness were measured immediately after the intervention.

Results Eleven hematological cancer survivors with an average age of 60.3 ± 10 years participated in the study.

Most participants were diagnosed with Follicular lymphoma and received maintenance treatment.

Participants had a significant (p < 0.05) increase in cardiorespiratory fitness by 2.6 ml/kg/min; and in peak workload, from 143.3 ± 60.6 W to 158.6 ± 67.5 W (p < 0.05).

Improvement in anthropometry and body composition was observed but yielded no statistical significance.

Most (80%) participants completed the three times/per week telesupervising exercise session for 12 weeks.No adverse event was identified.

Conclusion Findings from this study suggest that home-based CORE may provide hematological cancer survivors with an increase in CRF during the rehabilitation period after hospital discharge.

The telerehabilitation CORE model is effective, feasible, safe, and has demonstrated good adherence.

Further randomized controlled efficacy study with larger sample size is needed before clinical implementation.
