The cancer patient's perspective of COVID-19-induced distress-A cross-sectional study and a longitudinal comparison of HRQOL assessed before and during the pandemic.

BACKGROUND: To permit timely mitigation of adverse effects on overall clinical outcome, it is essential to understand how the pandemic influences distress and health-related quality of life (HRQOL) in cancer patients during the coronavirus disease 2019 (COVID-19) pandemic. METHODS: In this cross-sectional study, adult cancer patients, without COVID-19 symptoms, completed a 13-item questionnaire about the pandemic's impacts on distress and everyday-life; associations with age, sex, or impaired HRQOL were then assessed by binary logistic regressions. In a subsample of patients with HRQOL assessment available from both before and during the pandemic, we evaluated the pandemic's impact on longitudinal changes in HRQOL reported within 6 months before versus during the COVID-19 lockdown using McNemar's test, and thresholds for clinical importance. RESULTS: We consecutively enrolled 240 patients with solid (50%) or hematological (50%) cancers. Median age was 67 years, 46% were females. The majority ranked heeding their health (80%) and keeping their appointment schedule in hospital (78%) as important. Being younger than 60, or aged 60-70 was independently associated with limitations in everyday life (OR = 3.57, p < 0.001; and 2.05, p = 0.038); female individuals and those with restricted emotional functioning were more distressed by the COVID-19 situation (OR = 2.47, p = 0.040; and 3.17, p = 0.019); the latter group was also significantly more concerned about being a patient at risk (OR = 2.21, p = 0.029). Interestingly, in a subsample of patients (n = 47), longitudinal comparisons pre- versus during the pandemic revealed that HRQOL was not substantially affected by the pandemic. CONCLUSION: Particularly younger and female cancer patients, and those with impaired emotional functioning are distressed by COVID-19. During the first COVID-19 lockdown, cancer patients remained predominantly resilient. This analysis highlights the need to mitigate distress situations in vulnerable patients and thereby enhance resilience during pandemics.

Death of unknown cause? Post-mortem diagnosis of fulminant course of an EBV-associated secondary hemophagocytic lymphohistiocytosis.

HLH is a life-threatening disease, which is characterized by a dysregulated immune response with uncontrolled T cell and macrophage activation. The often fulminant course of the disease needs a fast diagnostic work-up to initiate as soon as possible the appropriate therapy. We present herein the case of a 71-year-old patient with rapidly progressive hyperinflammatory syndrome, which post mortem resulted in the diagnosis of EBV-associated HLH. With this case report, we intend to highlight the relevance of the HScore in the diagnosis of HLH, to create a greater awareness for EBV as a trigger of HLH, and to demonstrate the importance of treating EBV-associated HLH as early as possible.

Systematic review: Soluble immunological biomarkers in advanced non-small-cell lung cancer (NSCLC).

In the highly dynamic field of advanced malignancies, biomarkers from liquid samples are urgently needed to improve treatment tailoring. However, the heterogenic data lack direct comparison of assays, vectors and relevant validations are rarely found. Therefore, we classified the available studies based on three categories: Measured vectors, applied technique and detected biomarker. High blood tumor mutational burden and low baseline levels of soluble programmed cell death 1 ligand 1 (PD-L1) appear to predict treatment responses to immunotherapy. A high PD-1+ CD4+ T-cell count was associated with poor overall survival, PD-1+CD8+ T-cells connect to a favorable outcome. Circulating tumor cells expressing PD-L1 were mainly associated with poor overall survival and treatment failure. CONCLUSION: Measurement of immunological factors as liquid biomarkers is feasible and has shown promising results. The use of coherent nomenclatures, cross-platform assay comparisons and validations through appropriate powered clinical trials are urgently required to push this auspicious field.
