Prognostic value of pre-infection routine laboratory parameters for COVID-19 mortality in tumor patients: Results of the ADHOK Coronavirus Tumor Registry.
JOURNAL OF CLINICAL ONCOLOGY(2021)
摘要
10571 Background: Tumor patients (pts.) are considered susceptible to severe COVID-19 after SARS-CoV-2 infection. However, they represent a heterogeneous group of individuals with variable risk. Identification of vulnerable subgroups is important for prioritization of vaccination strategies and possible early therapeutic intervention after infection. Methods: Tumor pts. with PCR-confirmed SARS-CoV-2 infection were included in the multicentric ADHOK registry by 22 institutions. Detailed information about tumor disease and treatment, as well as routine laboratory parameters determined at least 10 days prior to SARS-CoV-2 infection, was collected retrospectively. The primary endpoint was defined as the outcome of the SARS-CoV-2 infection, graded according to the WHO: asymptomatic, mild, moderate, severe, critical, and COVID-19-related death. Results: Until Feb. 5, 2021, 215 pts. (67% with solid tumors, 33% with hematological neoplasms) were included in the registry. 74% of the pts. had an active malignancy. The course of SARS-CoV-2 infection was rather variable: 66% of the pts. remained asymptomatic or showed a mild-to-moderate course, while the rest developed severe or critical disease. The COVID-19-related mortality rate was 24%. Pre-infection routine laboratory values were available for 104 pts., obtained at a median of 21 days before SARS-CoV-2 infection. Compared to COVID-19 survivors, COVID-19 non-survivors showed significantly higher median levels of absolute neutrophil count (ANC: 3.6 vs. 6.4 /nL; p = 0.006, n = 91), neutrophil-to-lymphocyte ratio (NLR: 2.2 vs. 7.2; p = 0.005, n = 75), C-reactive protein (CRP: 9.9 vs. 42.0 mg/L; p = 0.001, n = 104), and lactate dehydrogenase (LDH: 213.0 vs. 267.0 U/L; p = 0.016, n = 78). When categorized by a median split, COVID-19 mortality was significantly higher in pts. with ANC > 4.4 /nL (4% vs. 55%, p < 0.001), NLR > 4.1 (5% vs. 58%, p < 0.001), CRP > 15.4 mg/L (18% vs. 46%, p = 0.003), LDH > 236 U/L (15% vs. 49%, p = 0.003) and lymphocytes < 1.3 /nL (41% vs. 11% p = 0.002). In multivariable analysis, ANC and CRP showed a strong and significant association with COVID-19-related death (OR 23.0 and 7.7, p = 0.007 and 0.029, respectively). To develop an easy-to-apply pre-infection score, we combined ANC and CRP and were able to separate three groups of pts. with significantly different COVID-19 outcomes (p < 0.001) (Table). Conclusions: Our results unveil subgroups of tumor pts. who may be at increased risk of severe COVID-19 and point to pre-infection routine laboratory parameters with potential prognostic power: ANC and CRP may help identify pts. at risk for severe COVID-19 before SARS-CoV-2 infection.[Table: see text]
