SALT LAKE CITY – Comprehensive assessment of functional status and endurance prior to allogeneic hematopoietic cell transplantation (HCT) provides important insights into posttransplant outcomes, and when used in combination with other measures may improve the patient selection process, a chart review suggests.
In 349 patients, results of the prospective assessment of physical performance and endurance, along with HCT Comorbidity Index (HCT-CI) score and Karnofsky Performance Scale score (KPS), were compared with day 100-plus nonrelapse mortality and overall survival. The measures were also compared with the novel measures of hospital length of stay, and death during HCT admission, Shabnam Rehman, MD, reported at the combined annual meetings of the Center for International Blood & Marrow Transplant Research and the American Society for Blood and Marrow Transplantation.
However, heart rate recovery in less than 3 minutes after performing 25 step-ups on each side was associated with shorter length of stay with 89% of those patients, compared with 11% of patients who were not able to recover their heart rate in less than 3 minutes, being discharged within 30 days, she said.
“Similarly, patients who are able to perform at least 11 sit-to-stands in 30 seconds are more likely to be discharged earlier (63% vs. 14% discharged within 30 days),” she said. “The converse is also true.”
That is, only 16% of those not able to recover their heart rate within 3 minutes had a 30-day or shorter stay, while 31% had at least a 60-day stay. In addition, just 13% of those with limited endurance had a 30-day stay or shorter, while 24% had at least a 60-day stay, she explained.
Further, patients with limited endurance, and those unable to perform 10 or more sit-to-stands in 30 seconds were more likely to die during their first transplant admission. Of those with limited endurance, 31% died during admission and 13% survived, and of those with good endurance 69% died during admission and 87% survived. Among patients who were unable to perform more than 10 sit-to-stands, 42% died during admission and 20% survived, and of those able to perform 11 or more, 38% died during admission, and 53% survived.
Overall survival was associated with age, KPS, HCT-CI, and age-adjusted HCT-CI, she noted.
“Patients who were over age 40 and more, and patients with a KPS of 60 or 70, belong to the high- to intermediate-risk group more likely to have decreased overall survival as has been shown in previous studies,” she said. “In addition to validating these findings, we also found that the semiquantitative measures, including pain and endurance, were also associated with overall survival.”
Those with pain present or limited endurance had significantly poorer overall survival (P = .007 and P = .01, respectively), and this finding was reflected in the quantitative measures of sit-to-stands (P = .01) and step-ups (P = .001), even when stratified by age-adjusted HCT-CI, she said.
In addition, a number of risk factors present at the pretreatment assessment were found to be significantly associated with requirement of an assistive device at discharge. These included pain, weakness in the lower extremities, use of an assistive device, inability to perform 25 step-ups and more than 10 sit-to-stands in 30 seconds, and limited endurance (P values ranging from .02 to less than .0001). Requirement of a device was associated with poorer overall survival (P = .03), she said.
Study participants were adults aged 18 years and older (median, 58 years) undergoing a first allogeneic HCT at a single center between 2010 and 2016. Most (83%) were older than age 40 years and 58% were men. About half (51%) had acute myeloid leukemia, and 64% overall had a KPS score of 60-70.
Physical therapists assessed physical performance of all patients within 4 weeks pre-HCT; testing included 25 7-inch step-ups on each side, unassisted sit-to-stands from an 18-inch chair in 30 seconds, weight-bearing ability, need for assistance with ambulation, motor strength in four extremities, sensory or coordination impairment, self-reported pain, and time to recovery of heart rate and oxygen saturation to pre-exercise levels.
“The HCT-CI is a validated tool that predicts nonrelapse mortality and overall survival, but comorbidity alone as a single domain is not a surrogate of overall health or reflection on the true biological age of our patients,” Dr. Rehman said, noting that studies have shown that functional impairment is associated with shorter overall survival, and that patient-reported physical functioning is predictive of overall survival. “The assessment of functional impairment becomes more critical given the aging U.S. population and older patients receiving transplant.”
Traditionally, functional status has been assessed via the KPS, which is a subjective measure and lacks precision, and the HCT-CI has not been studied in the context of the novel outcome measures addressed in the current study, she noted.
The current findings highlight the prognostic value of a more quantitative pretransplant assessment, which can help improve the patient selection process.
“We are in the process of analyzing some more outcomes of these pretransplant assessments, and developing a score that can, in conjunction with other predictive tools, help us improve pretransplant risk stratification and devise interventions that can improve the endurance and overall survival of the patients,” she concluded.
Dr. Rehman reported having no financial disclosures.
