Virtual coaching helps lymphoma patients tolerate chemotherapy better

During chemotherapy for lymphoma, side effects can become so severe that patients interrupt or abandon treatment altogether. A new study suggests that diet and exercise support during those months might change that equation.

Researchers at the University of Miami's Sylvester Comprehensive Cancer Center recruited 72 people undergoing standard chemotherapy for lymphoma. Half got immediate access to a virtual program pairing them with a registered dietitian and exercise physiologist for weekly sessions tailored to their needs. The other half waited for the program to begin after their treatment ended.

The results were striking. In the intervention group, anxiety dropped to 17% compared with 34% in the waitlist group. Depression fell from 67% to 46%. Fatigue, pain, and constipation all showed similar improvements. Patients also demonstrated greater grip strength and performed better on physical tests — a sign they were maintaining functional capacity through treatment.

But the real finding was simpler: 86% of patients stuck with their diet sessions and 81% attended exercise sessions, even while actively receiving chemotherapy. That's the kind of engagement researchers often struggle to achieve.

Why this matters

Chemotherapy works best when patients can tolerate their full prescribed dose. Research shows that receiving less than 85% of the planned treatment dose has real consequences for survival. When side effects force patients to skip doses or extend treatment timelines, the cancer's response weakens.

Melissa Lopez, who presented the findings at the American Society of Hematology Annual Meeting, points to a gap in how we've approached cancer care. "Most lifestyle work happens before treatment starts or after it ends," she says. "There's been a significant lack of data on how lifestyle during treatment impacts outcomes."

This study flips that script. The patients who received coaching felt stronger, experienced fewer symptoms, and — critically — were able to complete their full treatment plans. One woman might skip a chemotherapy session because the fatigue feels unbearable; another, working with an exercise physiologist, might push through because her grip strength tells her she's capable.

The next phase will measure whether this symptom relief actually translates to better treatment adherence and, eventually, better survival outcomes. But the feasibility is already proven. Patients can do this. Clinicians are referring patients. The infrastructure works.

The finding sits at the intersection of two truths: cancer treatment is brutal, and the human body is resilient when given the right support during crisis.
