Impact of COVID-19 Pandemic on Cancer Patients with Pulmonary Fibrosis on Chemosurveillance

COVID-19 infection and multiplication can be regulated with the aid of vaccines, immunosurveillance, and antiviral medications, such interferon and nucleoside analogs. The main concern with COVID-19 infection is the proliferation of the virus. However, there is no medication to treat pulmonary fibrosis, a life-threatening condition, once it has manifested. To treat critically ill patients with cancer and pulmonary fibrosis, it is imperative to develop cell differentiation agent (CDA) formulations that can kill cancer stem cells. Chemosurveillance for cancer patients no longer functions as intended. As a result, people with cancer are more likely to experience severe symptoms of pulmonary fibrosis. The harm to chemosurveillance caused by cancer treatments that focus on cell death, such as cytotoxic drugs, radiation, and immunotherapy, may gravely accelerate the development of fatal pulmonary fibrosis. To prevent the development of fatal pulmonary fibrosis symptoms, cancer patients should be advised against contracting COVID-19, but, if they do, targeted therapy should be their first choice. The purpose of this study was to highlight the significance of chemosurveillance in determining when fatal pulmonary fibrosis manifests after COVID-19 infection in cancer patients and to conceptualize CDA formulations that can be used to treat both pulmonary fibrosis and cancer. COVID-19 infection causes biological and immunological reactions that are similar to those of a wound, leading to the production of prostaglandins and tumor necrosis factor, which cause respiratory illness symptoms, such as fever and cough, and cachexia symptoms, respectively. This results in the breakdown of chemosurveillance, a natural defense mechanism that ensures optimal wound healing, thus further promoting the development of cancer and pulmonary fibrosis.
