Our oncologists receive many questions related to the new coronavirus infection from their patients. Is it true that cancer patients have a more severe disease and more often lead to complications? Is it possible to continue antitumor treatment in case of infection?
To date, experts have the results of only one early study on this topic, conducted in China and published in The Lancet Oncology journal.
Key research results:
- the study analyzed data from 1,590 COVID-19 patients from 575 hospitals in China who were admitted for treatment by January 31, 2020; Of the total number of patients, eighteen (1%) had a history of cancer.
- cancer patients also had additional risk factors: compared with other patients with COVID-19 who had no history of cancer, they were older, smoked more often, had more pronounced breathing difficulties and more pronounced changes on computed tomography;
- patients with oncological diseases were at higher risk of severe complications requiring hospitalization in the intensive care unit and connection to ventilators, and oncological diseases were associated with a shorter development time of complications.
Despite the low accuracy of the study due to insufficient data, the researchers draw attention to the need to strengthen individual protection measures against COVID-19 infection in patients with cancer and those who have suffered from cancer. There is also a need for more intensive monitoring or treatment of cancer patients infected with COVID-19, especially elderly patients or patients with other concomitant diseases.
Head of the Radiation Therapy Center EMC, oncologist, radiotherapist Nidal Salim:
"This is the first study aimed at assessing the risk of COVID-19 in patients with cancer. It is impractical to talk about statistical significance with such a small number — only 18 patients. Despite this, we cannot ignore the results. Like all patients with chronic diseases, patients with cancer should take special precautions to protect themselves from coronavirus infection, first of all, to limit contact as much as possible.
Treatment alone, whether drug or radiotherapy, does not increase the risk of infection, but may be a risk factor for complications. If COVID-19 is suspected in a cancer patient, doctors postpone active treatment until the test results are received."Oncologist, MD Pavel Koposov:
"Systemic drug antitumor treatment and elective surgeries in cancer patients with confirmed COVID-19 coronavirus are suspended until negative test results indicating recovery are received. Monitoring of cancer patients with coronavirus infection, including timely testing, cancellation of antitumor therapy and resumption of treatment, should be carried out by a multidisciplinary team."
