The findings, from a survey focused on patients’ willingness to travel for treatment, offer valuable insights on DLBCL patients’ perspectives and care needs, and on racial and sociodemographic variations among their perspectives and needs, the investigators said.
Treatment decision factors
They used a choice-based conjoint analysis to assess the relative value that 302 patients with DLBCL place on clinical factors, continuity of care, and travel time. Patients were asked to select treatment plans, choosing between pairs of hypothetical options that varied in travel time, follow-up arrangement, oncologist continuity, 2-year overall survival, and intensive care unit admission rate, the authors explained.
When all follow-up care in the hypothetical scenario was provided at the treatment center, plans requiring travel time of longer than 30 minutes were less attractive, Zachary A. K. Frosch, MD, and colleagues reported in the Journal of Clinical Oncology.
Importance weights, when compared with 30-minute travel time, were –0.54, –0.57, and –0.17 for 60, 90, and 120 minute travel time, they found.
However, scenarios involving shared follow-up by the treatment center and patients’ local providers mitigated the negative impact of travel on treatment plan choice, they noted (importance weights, 0.63, 0.32, and 0.26 at 60, 90, and 120-minute travel times).
Importantly, an analysis of responses based on sociodemographic factors showed that Black participants were less likely to choose plans requiring longer travel, regardless of follow-up arrangement, the authors said.
“Black patients were also less likely than White patients to choose treatment plans that offered lower continuity with their current oncologist (importance weights, 2.50 to vs. 1.09, respectively),” they wrote.
Further, when making choices that required trade-offs, treatment efficacy was a weaker driver of treatment plan preferences for Black patient than for White patients (importance weights, 0.34 vs. 0.75 per 5% point increase in overall survival, respectively).
Why the findings matter
“Certain cancer treatments aren’t offered everywhere. Examples of this are the bone marrow transplants and [chimeric antigen receptor T-cell] therapies used to treat patients with blood cancers such as lymphoma,” Dr. Frosch said in an interview, adding that the limited geographic availability of these treatments means that patients who need them may have to travel farther and also to establish care with a new oncologist.
“These are both things that some patients may be reluctant to do,” added Dr. Frosch, who was with the Perelman School of Medicine at the University of Pennsylvania, Philadelphia, at the time of the study, but is now assistant professor at Fox Chase Cancer Center in Philadelphia.
“We wanted to better understand how patients think about these trade-offs,” he said. “We found that they were less likely to choose treatments requiring more travel, or treatments that required them to transfer care to a new oncologist. This was the case, even if it meant choosing a treatment that might be less effective against their cancer. But when patients were offered a chance to have half of their follow-up appointments locally, travel was less of a barrier.”
Importantly, not all participants valued each aspect of treatments equally, Dr. Frosch noted, referencing the responses of Black versus White patients.
He and his colleagues stressed that while collaborative follow-up may ease access to more distant treatments for some patients, the lesser willingness among Black participants to travel for cancer therapy – regardless of follow-up arrangement – means that attention must be paid to unintended consequences, to avoid worsening the existing disparities in access to cellular therapies.
These data represent a step toward better understanding of how patients considering whether or not to travel for specialized cancer care weigh trade-offs, he said.
“However, we need to dig deeper into the issues we uncovered in future research, he added. “Our findings suggest that collaborative follow-up between the hospitals that offer these treatments and the oncologists in patients’ own communities could improve access to specialized cancer treatments. But I also think it’s important to understand that this may not be the solution for everyone, and so multiple and individualized strategies are going to be needed.”
