COVID-19 in patients with thoracic cancers: TERAVOLT
The global consortium TERAVOLT was established to determine factors that place patients with thoracic malignancies who develop COVID-19 at risk for hospitalization and death, to elucidate the clinical course of these patients and to identify therapeutic strategies that might impact survival. Thoracic cancer patients with a COVID-19 diagnosis, i.e. cases of confirmed infection according to RT-PCR techniques and suspected COVID-19 cases, are being entered into the database. The latter are defined by either clinical criteria (known exposure to a person with confirmed COVID-19 and symptoms such as fever > 37.5 °C, cough, diarrhea etc.) or lung imaging features consistent with coronavirus pneumonia and symptoms.
The analysis presented at ASCO 2020 included a global population of 400 patients with a median follow-up of 33 days from the COVID-19 diagnosis . At the time of data cut-off, 169 of patients had recovered, while 141 had died (35.5 %) and the infection was ongoing in 118. The median age across these groups ranged from 67 to 70 years. Most patients were male and current or former smokers.
Chemotherapy increases mortality
Presenting COVID-19 symptoms mainly included fever, cough, and dyspnea. In 78.3 % and 8.3 %, hospital and ICU admissions, respectively, became necessary. The median length of stay at hospital was 10 days. Among the patients who died, COVID-19 was the cause of death in 79.4 %, while only 10.6 % of fatalities were attributed to cancer. The most common complications in the deceased group comprised pneumonitis/pneumonia (71.0 %), acute respiratory distress syndrome (49.6 %), multiorgan failure (14.9 %), and sepsis (12.1 %).
Baseline risk factors for mortality from COVID-19 included age ≥ 65 years, performance status of 1 and presence of comorbidities (e.g., hypertension, COPD, vascular disease), while other factors such as gender, body mass index, smoking status, and stage or type of cancer did not affect the risk of death. Steroids (> 10 mg of prednisone or equivalent) or anticoagulation prior to the diagnosis of COVID-19 increased the risk, as did prior administration of chemotherapy alone or combined with immunotherapy, while immunotherapy and TKI treatment had no adverse effect on survival (Figure). No particular treatment for COVID-19 was associated with increased chances of recovery from the infection. Data collection is ongoing, and additional analyses are planned.
