A Canadian study of lung cancer patients who opted for “medical assistance in dying” often proceeded without consultation with their radiation oncologist or medical oncologist.
In a Canadian study of 45 individuals diagnosed with lung cancer who used medical assistance in dying (also known as physician-assisted suicide), about 20% did not have a radiation oncologist involved when making the decision and 22% did not have a consultation with a medical oncologist, said Sara Moore, MD, of Ottawa Hospital Research Institute of the University of Ottawa.
Since 2016, about 60% of those seeking to end their life through legal means introduced in Canada had been diagnosed with cancer, Dr Moore explained in a presentation at the virtual World Conference on Lung Cancer.
Driven by loss of autonomy, control and dignity
The designated discussant, Monica Malec, MD, a geriatric and palliative care physician at the University of Chicago, said this was the first study to evaluate medical assistance in dying in patients with lung cancer, oncologists’ involvement, and treatment history.
“The demand for medical assistance in dying is increasing and is becoming more readily available to patients,” Dr Malec said. “Patients are seeking this option despite the availability of more effective and more tolerable treatment options. Existing literature suggests that loss of autonomy, control, and dignity are the primary drivers for seeking medical assistance in dying rather than uncontrolled symptoms, and the decision to pursue medical assistance in dying may occur pre-illness.”
Moore noted that while lung cancer accounts for 20%-25% of all cancer deaths overall, in the current study 17.5% of the patients had lung cancer diagnoses. “Lung cancer comprises slightly fewer medical assistance in dying cases than expected compared to lung cancer death rates,” she said.
Improved treatments disregarded
“Biomarker-driven targeted therapy and immunotherapy offer effective and tolerable new treatments, but a subset of patients undergo medical assistance in dying without accessing — or, in some cases, without being assessed for — these treatment options,” Dr Moore continued. “Most patients were assessed by an oncology specialist, though less than half received systemic therapy.”
“Given the growing number of efficacious and well-tolerated treatment options in lung cancer, consultation with an oncologist may be reasonable to consider for all patients with lung cancer who request medical assistance in dying,” she said.
The researchers screened data from the Ottawa region, and identified 256 patients with a cancer diagnosis who had used medical assistance in dying. Of these, 45 patients had a lung cancer diagnosis.About 85% had a history of tobacco smoking, and 36% were current smokers at the time they sought medical assistance in dying, Moore reported. Thirteen of these patients had no biopsy confirmation of their disease, but almost all (91%) opting for medical assistance in dying were diagnosed with metastatic disease. Average age was 72 years, and 64% (29 of 45 patients) were women, even though men are more often diagnosed with lung cancer, Dr Moore noted.
Limitations included being limited to only a single region, and a lack of information on patients’ decision-making process.
