Immunotherapy
-
Background: Little is known about the 2019 novel coronavirus disease (COVID-19) course and outcomes in patients receiving immunotherapy. Here we describe a metastatic Merkel cell carcinoma patient with a severe acute respiratory syndrome coronavirus 2 infection while receiving pembrolizumab. Case presentation: A 66-year-old man, with a metastatic Merkel cell carcinoma receiving pembrolizumab, presented with fever. ⋯ Hydroxychloroquine was administered for 5 days, but discontinued after supraventricular extrasystoles. Clinical improvement allowed the patient's discharge after 81 days of hospitalization. Conclusion: A careful evaluation of oncologic patients receiving immunotherapy during the COVID-19 pandemic is of utmost importance.

Case Reports
Case report: use of lenzilumab and tocilizumab for the treatment of coronavirus disease 2019.
Background: Coronavirus disease 2019 (COVID-19) is a novel disease associated with a cytokine-mediated, severe, acute respiratory syndrome. Tocilizumab and lenzilumab are recombinant monoclonal antibodies against IL-6 and granulocyte macrophage colony-stimulating factor, respectively, and have been proposed as a potential treatment for acute, hypoxic respiratory failure associated with COVID-19. ⋯ He was subsequently treated with tocilizumab with marked clinical improvement and a decrease in acute phase reactants within 48 h. Discussion & conclusion: This case demonstrates the effective use of tocilizumab in the treatment of COVID-19 and suggests the superiority of tocilizumab over lenzilumab in the management of this cytokine-mediated syndrome.

Aim: To evaluate the cost-effectiveness of atezolizumab plus nab-paclitaxel (ANP) in the first-line treatment of metastatic triple-negative breast cancer (TNBC). Materials & methods: We developed a Markov model to evaluate the cost and effectiveness of ANP versus nab-paclitaxel in the first-line treatment of metastatic TNBC. Lifetime costs, life-years (LYs) and quality-adjusted LYs (QALYs) were estimated. ⋯ The corresponding incremental cost-effectiveness ratio was $786,131 per QALY gained. However, the incremental cost-effectiveness ratio decreased to $361,218 per QALY gained in the PD-L1 positive subgroup analysis. Conclusion: From the perspective of a US-payer, ANP is estimated not to be cost-effective in the first-line treatment of metastatic TNBC.
