ABSTRACT

Background:

The mortality rate of cancer patients diagnosed with COVID-19 infection has reached 25%. The time from symptom onset to admission to the intensive care unit (ICU) was on average 10 days, with approximately 26% of patients requiring ICU admission. A higher mortality attributed to COVID-19 was seen in older patients, patients with certain cancer types, and patients with a higher Charslon comorbidity score. Moreover, male sex and leukopenia at diagnosis were associated with an increased risk of worse clinical outcomes. Furthermore, a study done at Memorial Sloan Kettering showed that patients with hematological malignancies had a worse prognosis than those with solid tumors. Our aim is to identify the predictive factors for ICU admission in the setting of positive COVID-19 infection in cancer patients. Differences in prognosis were compared between cancer and non-cancer patients admitted to the ICU due to COVID-19 infection. We also compared the overall outcome between patients with solid cancers and hematologic malignancies.

Methods:

This is a single institution retrospective study based on chart review analysis conducted at the American University of Beirut Medical Center (AUBMC). 248 patients were diagnosed with COVID-19 from 1 January 2020 to 31 December 2021. The patient groups were (1) all cancer patients admitted to the COVID unit, (2) all cancer patients admitted to ICU, and (3) all other patients without cancer admitted to the ICU. The main outcomes were ICU admission and mortality.

Results:

173 cancer patients were admitted to our institution for the management of COVID-19 with a mean age of 63 years. 52 patients (30%) required ICU admission and 50 patients (29%) died during hospital stay or 1 month following discharge. The time from symptom onset to ICU admission and death were 12.8 and 35 days, respectively. Patients admitted to the ICU were more likely to have anemia (Hb < 8 g/dL) and thrombocytopenia (< 50,000/ mm3) on admission (p = 0.001). Age, male sex and history of smoking, diabetes or cardiopulmonary diseases were not associated with greater risk of ICU admission or death. Among cancer patients, those with uncontrolled disease at the onset of COVID-19 had greater risk of death from COVID-19 (p = 0.001). Cancer type, number of lines of treatment, history of radiation to the chest, recent cytotoxic therapy, and neutropenia were not associated with ICU admission or death from COVID-19. There was no statistical significance in mortality or disease progression between patients with solid or hematologic malignancies.

Conclusions:

Our data reaffirms previously reported findings of high mortality in cancer patients who contract COVID-19. In particular, patients with anemia, thrombocytopenia, and uncontrolled disease at diagnosis had unfavorable outcomes. Contrary to the literature, age, male sex, cancer type, and neutropenia were not predictive factors for mortality in cancer patients in the setting of COVID-19 infections.
