ABSTRACT
Neutrophil-to-lymphocyte ratio (NLR) has been studied as a prognostic factor for mortality in COVID-19 patients. Our study aimed to evaluate the association between NLR at COVID-19 diagnosis and survival during the following 90 days in hospitalized patients with solid cancer. Between May 2020 and June 2021, 120 patients were included in a retrospective cohort study. Univariable analysis showed patients with an NLR > 8.3 were associated with an increased risk of death (HR: 4.34; 95% CI: 1.74-10.84) compared to patients with NLR < 3.82 and with NLR ≥3.82 and ≤8.30 (HR: 2.89; 95% CI: 1.32-6.36). Furthermore, on multivariable analysis, NLR > 8.30 independently correlated with increased mortality. In patients with solid malignancies with COVID-19, an NLR > 8.3 is associated with an increased risk of death.

PURPOSE: In recent years, unprecedented benefits have been observed with the development of cyclin-dependent kinase (CDK) 4 and 6 inhibitors for the treatment of hormone receptor-positive/human epidermal growth factor receptor 2-negative metastatic breast cancer. However, there is scarce evidence of their value in specific populations, such as patients carrying germline pathogenic variants in DNA repair-related genes. PATIENTS AND METHODS: We retrospectively studied the efficacy of CDK 4/6 inhibitors plus endocrine therapy in patients with hormone receptor-positive/human epidermal growth factor receptor 2-negative advanced breast cancer. Three cohorts were compared, including patients harboring germline pathogenic variants in DNA repair-related genes (gBRCA1/2-ATM-CHEK2 mutated), those tested without these mutations (wild type [WT]), and the nontested subgroup. Relevant prognostic factors including age, metastatic site (visceral v nonvisceral), Eastern Cooperative Oncology Group, and prior treatment with CDK 4/6 inhibitors were stratified by univariate and multivariate Cox regression models. RESULTS: Among the total population (n = 217), 15 (6.9%) patients carried gBRCA1/2 (n = 10)-ATM (n = 4)-CHEK2 (n = 1) pathogenic variants, 45 (20.7%) were WT, and 157 (72.4%) were nontested. Gene pathogenic variant carriers were younger (P < .001). Most patients (164, 75.6%) had not received prior endocrine therapy in the advanced setting. Median progression-free survival was shorter in patients with evaluated germline pathogenic variants (10.2 months [95% CI, 5.7 to 14.7]), compared with WT and nontested patients (15.6 months [95% CI, 7.8 to 23.4], and (17.6 months [95% CI, 12.9 to 22.2]; P = .002). Consistently, a worse median overall survival was observed in the subgroup with germline pathogenic variants than in the WT group (P = .006). Multivariable analysis showed that mutation status was an independent prognostic factor of progression-free survival (P = .020) and overall survival (P = .012). CONCLUSION: In this retrospective real-world study, gBRCA1/2-ATM-CHEK2 pathogenic variants were independently associated with poor outcomes in patients with advanced breast cancer treated with CDK4/6 inhibitors.

Cancer patients are exposed to more complications from COVID-19 than non-cancer patients. We report a cohort of 74 cancer patients (87.8% with solid neoplasia and 12.2% with hematological diseases) with COVID-19 infection admitted to a tertiary medical cancer center in Argentina. Pulmonary infiltrates were diagnosed at admission in 78.3% (N = 58) of the cases. COVID-19 infection was hospital-acquired in 20 (27.0%) patients. Thirty-nine patients (52.7%) received anticancer therapy within the 30 days prior to COVID-19 diagnosis; one was on radiation therapy. Twenty-four (32.4%) patients were admitted in the intensive care unit (ICU) and 18 (75.0%) required mechanical ventilation. All cause in-hospital mortality was 32.4% (N = 24) and ICU mortality was 62.5% (N = 15). Mortality under mechanical ventilation was 72.2% (N = 13). In the univariate analysis age, neutrophil count, neutrophil/lymphocyte index, D-dimer, ferritin, smoking, and nosocomial acquired infection were associated with in-hospital mortality. There were no statistically significant differences in mortality related to disease stage for solid tumors, neither cancer treatment within 30 days of COVID-19 diagnosis. Age and smoking were associated with mortality in the multivariate analysis. The adjusted odds ratios (95 CI) for age = 65 years and smoking were 8.87 (1.35-58.02) and 8.64 (1.32 - 56.64), respectively. Our experience can be useful for other institutions that assist cancer patients during the pandemic.
Los pacientes con cáncer y COVID-19 tienen más complicaciones que la población general. Comunicamos una cohorte de 74 pacientes con cáncer y COVID-19 internados en una institución oncológica. El 87.8% tenía diagnóstico de tumores sólidos y 12.2% oncohematológicos. Entre los tumores sólidos, el 61.5% presentó enfermedad metastásica. El 78.3% (N = 58) tenía infiltrados pulmonares al diagnóstico de COVID-19. La infección fue intrahospitalaria en 20 pacientes. Habían recibido tratamiento antineoplásico dentro de los 30 días anteriores al diagnóstico 39 pacientes (52.7%); uno se encontraba recibiendo radioterapia. Veinticuatro pacientes (32.4%) se derivaron a terapia intensiva (UTI) y 18 (75%) de ellos requirieron asistencia respiratoria mecánica (ARM). La mortalidad general durante la internación fue 32.4% (N = 24). La mortalidad en UTI fue 62.5% (N = 15). La mortalidad en ARM fue 72.2% (N = 13). La edad, recuento de neutrófilos, índice neutrófilo/linfocito, dímero D, ferritina, tabaquismo y haber adquirido la infección durante la internación resultaron estadísticamente significativos en el análisis univariado para mortalidad. No hallamos diferencias en mortalidad por estadio de enfermedad, en los pacientes con tumores sólidos, ni por haber recibido tratamiento antineoplásico dentro de los 30 días del diagnóstico de COVID-19. En el análisis multivariado con el modelo de regresión logística, solo la edad y el tabaquismo fueron predictores de mortalidad. Los odds ratios (IC 95) ajustados para la edad =65 años y el tabaquismo fueron 8.87 (1.35-58.02) y 8.64 (1.32-56.64), respectivamente. Este trabajo puede resultar de utilidad para instituciones polivalentes que asistan pacientes oncológicos durante la pandemia.
