VA Researchers Say Opioid Guidelines Should Include Cancer Patients
/By Pat Anson
Most medical guidelines that limit the use of opioid pain medication are intended only for patients suffering from “non-cancer” pain. The CDC, for example, says that its guideline “does not apply to patients undergoing cancer-related pain treatment,” because the potential for addiction and overdose “might not be relevant” to patients at risk of dying.
That long-held policy is now being questioned. In a study published in CANCER, the medical journal of the American Cancer Society, VA researchers say cancer patients are living longer and may be at risk of “persistent opioid use.”
The study, led by researchers at the VA Medical Center in Philadelphia and the Perelman School of Medicine at the University of Pennsylvania, followed over 9,000 veterans who had surgery for early-stage cancer, mostly prostate, colon, bladder or lung cancers. About a third of those patients also needed chemotherapy, immunotherapy or radiation therapy.
Thirteen months after surgery, about one in ten patients (10.6%) were still prescribed opioids for pain relief. And about 4% of them were co-prescribed benzodiazepines for anxiety, a combination of medications that some consider risky.
Although none of the veterans overdosed from taking opioids, and less than one percent (0.78%) were diagnosed with opioid use disorder, researchers say stronger measures are needed to limit the use of opioids by cancer patients.
“Minimizing opioid exposure associated with cancer treatment while providing effective pain control will decrease long-term health risks among cancer survivors,” said lead author Marilyn Schapira, MD, Professor of Medicine at the University of Pennsylvania and Co-Director at the Center for Health Equity Research at the VA Medical Center.
“Prescription opioid practices associated with cancer treatment may lead to unsafe and long-term opioid treatment (LTOT) and the related adverse outcomes of opioid use disorder, opioid overdose, and nonoverdose adverse events, including suicide.”
Schapira and her colleagues say medical guidelines that exclude cancer patients from opioid prescribing limits, such as the CDC guideline and the Department of Defense/Veterans Affairs guideline, should be rewritten.
“There may be benefits to extending general guidelines regarding prescription opioids to those facing cancer treatment in consideration of health and well-being during the years of survivorship," researchers concluded. “Efforts should be taken to mitigate long-term opioid use and its potential adverse effects in this population. This is especially true because cancer is increasingly recognized as a chronic condition, and survivors of cancer are living longer.”
Cancer patients with a history of chronic pain, greater comorbidities, lower socioeconomic status, and those who received chemotherapy were said to be at “especially high risk of opioid use in the year after surgery.”
Regardless of what the guidelines say, many U.S. patients being treated for cancer already have trouble getting opioids for pain control. A recent study found a 24% decline in opioid prescribing to cancer patients on Medicare after the CDC’s 2016 guideline. Another study found the number of cancer patients seeking treatment for pain in hospital emergency rooms doubled. About a quarter of the patients had cancer pain so severe they were admitted.
Other studies have found that cancer patients are getting smaller and fewer doses of opioids, while some can’t get them at all. A recent survey of palliative care doctors in New York City found that nine out of ten (88%) reported frequent obstacles in getting opioids for their patients due to tight supplies at pharmacies. Nearly a third said the shortages resulted in sub-optimal care for their patients.
One of the more egregious examples of a cancer patient being unable to get opioids was the case of April Doyle, a California woman with metastatic breast cancer who couldn’t get her Norco prescription filled at a Rite Aid pharmacy. April recorded a tearful video in the pharmacy parking lot and shared it online, where it went viral. Outrage over the incident led to an apology from Rite Aid and her prescription being filled. April died a year later at the age of 42, leaving behind a 9-year-old son.
