prognosis than the general population, either due to their own disease or due to the treatments they
receive. The current epidemiological situation represents a challenge for professionals and institutions,
especially when we take into account the scarce and limited evidence generated in the pandemic. Decision-
making should be individualized based on the need for care and the risk of exposure to SARS-CoV-2,
always considering the wishes and preferences of patients, as well as the ethical aspects.

When considering future perspectives, major efforts and coordination must be undertaken by health
[94]
and political authorities and institutions to improve the fight against COVID-19 . As in the case of
target therapies for lung cancer and other fields of medicine, molecular biology may play a key role in the
[95]
discovery of new treatments and vaccines for SARS-CoV-2 . Technology, including telemedicine, artificial
intelligence and may play a major role in the management of the actual crisis, as well as the health care and
diagnosis of lung cancer patients.

In this work, we attempted to summarize the main evidence and topics linking COVID-19 and lung cancer,
while also recognizing that this is not a systematic review of the literature nor a meta-analysis. We consider
this to be the main limitation of our study, as there may be published literature or important topics
overlooked in this review.
