COVID-19 & Cancer: Survival Rates Declined During Pandemic | JAMA Oncology Study

The Covid-19 pandemic created a ripple effect, impacting healthcare systems globally and indirectly affecting treatment for other serious illnesses. A recent study published in JAMA Oncology revealed that cancer patients in the United States experienced reduced survival rates during 2020 and 2021.

A System Under Strain

The Impact of Disruption

Researchers haven’t pinpointed a single cause for this decline, but Todd Burus, an author of the study and a graduate of the University of Kentucky, suggests that the saturation of the healthcare system and disruptions in medical care played a significant role. The Associated Press reported that these disruptions “probably played a key role” in the decreased survival rates.

Did You Know? Between 2015 and 2019, approximately 17,400 patients died after a cancer diagnosis, compared to nearly 144,000 who died between 2020 and 2021.

Early in the pandemic, public health recommendations to stay home and avoid crowded places led many individuals to postpone or cancel crucial cancer screenings, including colonoscopies, mammograms and lung scans. Simultaneously, hospitals became overwhelmed with Covid-19 patients, forcing other medical needs to take a backseat.

The Numbers Tell a Story

A Significant Increase in Mortality

Between 2020 and 2021, over one million people in the United States were diagnosed with cancer, and approximately 144,000 died, with those diagnosed surviving, on average, just over a year. This represents a substantial increase in mortality compared to the 2015-2019 period.

Expert Insight: The study highlights the critical interconnectedness of healthcare systems. When one area, like pandemic response, is severely stressed, it can have devastating consequences for patients with other serious conditions, even if those conditions aren’t directly related to the initial crisis.

The cancers most affected by this trend include colorectal, prostate, and pancreatic cancers, where the decline in survival rates was most pronounced. Experts caution that these figures reflect not only the direct impact of the virus but also the consequences of delayed preventative care and essential treatment postponements.

Looking Ahead

The Path to Recovery

The research indicates a setback in the fight against cancer during the pandemic, emphasizing the importance of early detection and timely access to treatment to improve survival probabilities. While the acute phase of the health emergency has subsided, the recovery of the healthcare system and the reactivation of preventative programmes remain urgent priorities to mitigate the losses caused by Covid-19.

Frequently Asked Questions

What types of cancer were most affected during the pandemic?

Colorectal, prostate, and pancreatic cancers showed the most significant declines in survival rates, according to the study.

What factors contributed to the decrease in cancer survival rates?

The study suggests that saturation of the healthcare system and disruptions in medical care were important contributing factors.

How did the pandemic impact cancer screenings?

The recommendation to stay home and avoid public places led many people to postpone or cancel important cancer screenings like colonoscopies, mammograms, and lung scans.

How might healthcare systems better prepare for future public health crises to minimize disruptions in care for non-pandemic related illnesses?
