Different Behavioral Patterns of SARS-COV-2 in Patients with Various Types of Cancers: A Role for Chronic Inflammation Induced by Macrophages

SARS-CoV-2 is a single strand RNA virus that causes ongoing pneumonia-like and severe respiratory disease. This disease is very important in immunosuppressed patients. Since not many studies have been done in people with cancer as high risk group, in this study we examined the different behaviors of this virus in different types of cancer. In this study, patients with a variety of solid and hematologic cancers were screened for SARS-CoV-2. The rates of infection, the rate of mortality, in patients with various cancers, as well as in the families of these patients have been studied. In this study, it was found that the prevalence of SARS-CoV-2 in patients with solid cancers was significantly lower than hematological cancers. Also, the mortality rate in hematological cancers was higher than in solid cancers (P<0.05). Assessments the families of these patients, it was found that patients with solid cancers were also less infected than their family members (P<0.05). Researchers of this study attributed these results to the chronic inflammation and M1 macrophages in these patients. It is essential that additional studies are conducted, especially in terms of biological function.
