A new, robustly detailed retrospective cohort study on the incidence of cardiovascular disease (CVD) in more than 4,500,000 adult cancer patients published today in JACC: CardioOncology.
Clinical trials in oncology generally exclude patients with CVD, and randomized controlled trials on CVD generally do not include detailed cancer-related information. In this study, researchers make it apparent that the growing and unmet medical needs of cardio-oncology patients demand a new methodology to meet them.
"As the life expectancy of cancer patients increases, so does the likelihood of developing other illnesses after that diagnosis," said Ian Paterson MD, first author of the study and professor of medicine at the University of Alberta. "Our findings highlight the need for an even more collaborative approach to health care for cancer patients and survivors."
The authors found that, regardless of the cancer site, a new cancer diagnosis presents a significantly higher risk of cardiovascular mortality, heart failure, stroke or pulmonary embolism, especially in patients with genitourinary, thoracic, hematological and gastrointestinal cancers.
The causal relationship between CVD and the patient, cancer and treatment remains controversial. The primary elements of that relationship are that each patient presents specific and multifaceted risk factors for CVD; cancer itself is impacted by patients' physical and mental health, often exacerbated by socioeconomic circumstances; and the course of each patient's cancer treatment.
