A new study shows that drug shortages are affecting seriously ill cancer patients. Doctors say in some cases they've had to delay treatment.
Hundreds of drugs have been in short supply in recent years, including many to treat cancer. Researchers at the University of Pennsylvania School of Medicine surveyed nearly 250 oncologists and found 83 percent of doctors said they have faced drug shortages.
"Our survey found that thousands of patients have had their treatment regimens changed because of drug shortages," says Dr. Keerthi Gogineni of Penn's Abramson Cancer Center.
43 percent of doctors had to delay their patients' treatment and 37 percent had to choose among patients who needed a particular drug.
"They need to prioritize when there is limited drug availability," Gogineni says. "These decisions are fraught with ethical complications."
Previous research from last December found a link between drug shortages and higher rates of relapse in lymphoma patients like Abby Alonzo. she was forced to switch medication right in the middle of her treatment.
Problems with quality and manufacturing are behind many drug shortages in the US. But since last year, manufacturers are required to notify the FDA of shortage problems. The agency says it's been able to lower the number of drug shortages and also prevent some from happening.
The survey also found that nearly 40 percent of cancer doctors said they had to switch their patients from generic drugs to more expensive brand name medications.
