The nefarious duo: Cancer and COVID-19

Seeking the balance point and taking the first steps in decision making

James Fleck: Anticancerweb 28 (04), 2020

Despite the difficulties expected in the organization of health resources during a pandemic, the predicted problems can be mitigated with a rational approach. The social distance strategy was promoted as an effective historical alternative toward early intervention during outbreaks of rapidly evolving diseases. Promptly, lead time is used to better equip the health system, providing conditions to support the growing demand. The COVID-19 Dashboard by the Center for Systems Science and Engineering at Johns Hopkins is now showing worldwide more than 3 millions confirmed cases, leading to 212,221  deaths. The health care system in some European countries and some US states has already faced and are still struggling with undesirable overload. Patients with comorbidities are at higher risk for severe acute respiratory syndrome and need for Intensive Care Unit (ICU) support. Data, first reported from China, revealed 39% of COVID-19 confirmed cancer patients requiring ICU support. This finding, although preliminary, has generated uncertainties in the recommendations for diagnosis, treatment and monitoring of cancer patients. This is an unusual time when the guidelines for cancer treatment need to be temporarily revised. Although it is impossible to use a single model, the general recommendations would contribute to a better organized system. In addition, our current knowledge of tumor biology and its clinical behavior has shown that some tumors do not require immediate intervention.

Recently published in Annals of Internal Medicine, the article called "A War on two Fronts" draws attention to the treatment of cancer during the COVID-19 pandemic. A group of well-recognized physicians from the Fox Chase Cancer Center, Philadelphia, Pennsylvania, USA, proposed general recommendations for cancer care as long as the pandemic scenario persists. Suggestions were made based on patient protection. The strategy emphasizes the concept of mitigation. The reduction of severe cases in the health system reduces the risk of overload, preventing an unacceptable increase in the mortality rate. The natural vulnerability of cancer patients, ironically combined with adverse events related to surgery, chemotherapy or radiation therapy, requires a balanced decision-making process. In this atypical period of time, some diagnostic and therapeutic procedures can be postponed with relative safety due to the indolent biological behavior of some tumors. On the other hand, aggressive tumors must be treated immediately. Looking both ways in the current pandemic scenario, cancer screening should be postponed and futility should be avoided, more than ever, in terminally ill patients. In clinical trials, the integrity of ongoing studies should be preserved, with special attention to patient safety during the pandemic. Telemedicine should be implemented, providing good quality services and avoiding unnecessary traveling to a health care facility. As history has shown, the pandemic will pass, but a lesson on adaptive flexibility will be learned.
