Brief summary

This study aims to see if a 12-week exercise program designed to reduce long periods of inactivity is feasible in newly diagnosed lymphoma participants receiving R-CHOP or POLA-R-CHP chemotherapy treatments, and whether it can improve heart health and reduce chemotherapy drug side effects.

Detailed description

The purpose of this study is to see if a 12-week exercise program designed to reduce long periods of inactivity is feasible in newly diagnosed lymphoma participants receiving R-CHOP or POLA-R-CHP chemotherapy treatments, and whether it can improve heart health and reduce chemotherapy drug side effects. Participants will be randomized into one of two groups: Group A: Interrupted Sedentary Time Intervention vs. Group B: Usual Care Control Group. Randomized means a participant is placed into a study group by chance. The research study procedures include screening for eligibility, assessments of fitness and physical health, blood tests, and questionnaires. Participation in this research study is expected to last about 3 months. It is expected that about 24 people will take part in this research study.

Interventions

BEHAVIORALInterrupted Sedentary Time Intervention

A 12-week, semi-supervised exercise intervention comprised of reminder prompts, counseling, and activities of walking, cycling, and resistance band exercise for at-home and in-clinic settings. Supervision will be under an exercise trainer. Resistance bands, Libre Pro continuous blood sugar monitor, and Fitbit and ActivPAL trackers will be provided to participants.

Inclusion criteria

* Ability to understand and the willingness to sign informed consent prior to any study- related procedures. * Patients diagnosed with lymphoma. * Will receive first line R-CHOP or POLA-R-CHP chemotherapy regimens, patients do not need to be within a certain timeframe from diagnosis. * Aged ≥18 years; due to the rarity of the disease in those \<18 years, this age bracket will not be included. * Engaging in ≤60-minutes of structured moderate or vigorous intensity exercise. * Have physician clearance to participate in exercise. * Speak English. * Willing to travel to Dana-Farber Cancer Institute for necessary data collection and exercise sessions. * Access to a phone that can receive text messages.

Exclusion criteria

* Unstable comorbidities that prevent participation in moderate-to-vigorous intensity exercise. Patients with unstable comorbidities likely require supervised exercise for safety, and part of this study involves unsupervised exercise; therefore, for safety reasons, these persons are excluded. * Participate in more than 60 minutes of structured moderate-to-vigorous exercise per week over the last month. Excess additional exercise is a confounding factor in assessing the effect of the current interrupted sedentary time intervention. * Patients receiving treatment for other active malignancies (except basal cell carcinoma). This study is exclusively targeting lymphoma chemotherapy-related effects. * Patients currently taking weight loss drugs. * Subjects who in the opinion of the investigators may not be able to comply with the safety monitoring requirements of the study. * Unable to travel to DFCI Longwood campus for necessary data collection and chemotherapy infusions.

Design outcomes

Primary

MeasureTime frameDescription
Intervention Completion Rate (Feasibility)12 weeksIntervention feasibility is defined as: 1) A participant completes ≥70% of the supervised activity breaks on at least 3 out of the 4 infusion appointments. 2) A participant completes ≥70% of the prescribed home-based resistance activity breaks on at least 48 days out of the possible 68 days (12 week) intervention (excluding the 4 infusion days and 1 rest day per week) (i.e., meet interrupting sedentary behavior goals across at least 70% of the intervention). 3) A participant completes ≥70% of the prescribed home-based step goals (i.e., \>250 steps per hour) on at least 48 days out of the possible 68 days (12 week) intervention (excluding the 4 infusion days and 1 rest day per week) (i.e., meet interrupting sedentary behavior goals across at least 70% of the intervention).
Refusal Rate12 weeksDefined as ≤50% of eligible screened participants refuse to complete intervention.
Retention Rate13 weeksRetention of consented participants to study end is ≥70%.
Acceptability of Intervention Measure (AIM) Scale13 weeksAssessed by the Acceptability of the Intervention Measures, a 4-item measure rated on a 5-point Likert scale with answers ranging from "Completely disagree" to "Completely agree." A total scores range is 4 to 20 with a higher score indicating greater acceptability. The intervention will be deemed acceptable by participants if ≥70% of participants have a mean score ≥ 4 on the AIM.
Acceptability Exit Survey13 weeksThe intervention will be deemed acceptable by participants if 1) ≥70% of participants report "agree" or "strongly agree" to the prompt "Participation in this study helped me reduce my daily sedentary time" and 2) ≥70% of participants report "probably" or "yes" to the prompt "I would recommend this program to other patients being treated for cancer."

Secondary

MeasureTime frameDescription
Participant Glucose LevelAssessed for one week at each timepoint (baseline & post-intervention).Glucose levels will be assessed by constant glucose monitoring where an average of \>180 mg/dl will be considered hyperglycemic.
Participant Insulin ResistanceAssessed for one week at each timepoint (baseline & post-intervention).Insulin resistance will be assessed by calculating Homeostatic Model Assessment for Insulin Resistance (HOMA-IR) from fasting blood samples where values \>1.9 will be considered insulin resistant.
