SAN DIEGO – When it comes to aggressive care at the end of life, hematologists stand alone.
Dr. David Hui
Hematology patients are more likely than are other patients to undergo chemotherapy and visit emergency departments and intensive care units when they’re near death, and they’re less likely to be referred for palliative care, according to David Hui, MD, an oncologist and palliative care specialist at the MD Anderson Cancer Center in Houston.
An analysis at the center, for example, found that 43% of hematology cancer patients received chemotherapy within the last 30 days of life, compared with 14% of patients with solid tumors.
“That’s not a number we’re proud of,” Dr. Hui said at the annual meeting of the American Society of Hematology. “Ultimately, at the end of life, do we want our patients to be in this setting? There is room for improvement.”
The cancer center isn’t an outlier on this front, Dr. Hui said. Data from other institutions in the United States and internationally confirm that hematologic oncologists tend to provide more aggressive care at the end of a patient’s life, compared with other cancer specialists.
“If you’re one of those patients, this is a very big deal,” said Dr. Hui, especially in light of data that suggest hematology patients get fewer referrals to palliative care than do other cancer patients. “Oncologists are optimistic, and hematologic oncologists especially,” he said.
Dr. Hui led a 2014 study of 816 adult cancer patients who died while under care at MD Anderson Cancer Center during 6 months in 2009 and 2010 (Cancer. 2014 May 15; 120[10]:1572-8).
“We found that patients with hematological malignancies were more likely to have multiple emergency room visits, intensive care unit admissions and death, and cancer treatments in the last weeks of life compared to patients with solid tumors,” the study authors wrote. “We also identified a relative lack of palliative care involvement in hematologic patients.”
Specifically, hematology cancer patients were much more likely to get aggressive end-of-life care than were the other cancer patients (odds ratio, 6.63, P less than .001).
Dr. Hui had led an earlier study that looked at the same 816 cancer patients and found that 45% had received palliative care consultations. But the researchers also found that patients with hematologic malignancies had significantly fewer palliative care referrals, the longest time between an advanced cancer diagnosis and a palliative care consultation, and one of the largest numbers of medical team encounters – a median of 38 – before palliative care (Oncologist. 2012;17[12]:1574-80).
In light of these numbers, policies at MD Anderson Cancer Center “are evolving rapidly,” Dr. Hui said.
He urged colleagues to think about the wishes of their patients. “What do patients really want? Good symptom control, time with family, not being a burden, not a prolonging dying process, having a sense of control during the middle of the turmoil.”
Dr. Hui added that the attitudes of oncologists regarding palliative care can affect whether patients get timely referrals to consultations. He led a 2016 study that surveyed 182 oncologists about end-of-life care and found that “many oncologists have a favorable attitude toward EOL care; this, in turn, was associated with greater provision of primary palliative care and higher rates of referral to specialist palliative care.”
However, “we found that hematologic oncology specialists expressed lower comfort levels compared with their solid tumor counterparts,” a finding that reflects the results of other studies, the study authors wrote (Oncologist. 2016 Sep;21[9]:1149-55).
The stigma surrounding palliative care is a sticking point, Dr. Hui said, and has sparked a “rebranding” effort. Negative feelings about palliative decrease when it’s called “supportive care,” he said, and the new term is being adopted worldwide.
Dr. Hui reported having no financial disclosures.
