Cancer and COVID-19 (multiple reviews)

Added December 3, 2020

What is this? The COVID-19 pandemic is having an impact on cancer care and cancer patients. Several systematic reviews are summarised here, including rapid reviews of COVID-19 infection in cancer patients and the treatment and management of cancer patients during the COVID-19 pandemic. More details on each review, including citations and links to the full versions, are provided lower down this page.

What was found: Overall, the studies included in these reviews suggest that people with cancer may be more likely to contract COVID-19 than people without cancer and may be at higher risk of severe infection, complications and death. Recommendations have been made to try and protect cancer patients from COVID-19 infection, which include delaying treatment, but this may impact on their cancer outcomes.

The Moujaess review (search done on 5 April 2020) found that COVID-19 can present differently in patients with cancer compared to the general population, which might make COVID-19 diagnosis more challenging in patients with cancer. They also reported that cancer treatments and cancer research had been adversely affected by the COVID-19 pandemic.

The Giannakoulis review (search done on 27 April 2020) found that COVID-19 patients with cancer had higher all-cause mortality than COVID-19 patients without cancer and that they were more likely to need ICU admission.

The Afshar review (search done on 7 May 2020) found case fatality rates in patients with COVID-19 and cancer ranging from 5.5% to 60% and that the proportion of severe COVID-19 cases was higher in patients with cancer than in those without cancer.

The reviews by Tian (search done on 23 April 2020) and Zaki (search done before 23 June 2020) found that cancer patients may be at higher risk of COVID-19 infection, severe infection and poorer outcomes.

The Spolverato review (search done on 4 April 2020) found that recommendations to reduce infection and mortality from COVID-19 in cancer patients included postponing non-essential treatments, providing patients with adequate PPE, case-by-case evaluation for surgery and separate facilities.

The Fligor review (search done on 23 March 2020) found that delayed surgery for colorectal cancer may worsen survival, but that the impact on outcomes for patients with pancreatic or gastric cancer was unclear. The authors noted that neoadjuvant treatment should be considered if surgery is delayed.

The Garg review (search done on 2 May 2020) found many cancer guidelines that had been rapidly developed during the COVID-19 pandemic, which were based on limited evidence. They noted marked discordance in recommendations across sub-specialities and concluded that the guidelines should be interpreted with caution.
