Background: T-cell-engaging bispecific antibodies (BsAbs) are a newer type of immunotherapy designed to boost T-cell cytotoxicity. They are increasingly used in cancer treatment, with drugs currently being tested and authorized for treating both liquid and solid tumors. It's becoming more likely that emergency physicians and other acute care practitioners will treat patients experiencing adverse events related to bispecific antibodies, as these drugs are regularly given in the outpatient setting. Currently, BsAb-associated side effects are not routinely taught to Emergency Medicine residents, and a paucity of literature exists to guide currently practicing Emergency Medicine physicians and other acute care practitioners about these medications., Objective of the Review: This review was written by emergency medicine physicians in collaboration with oncologists who routinely administer BsAbs to provide guidelines and an overview on diagnosis, treatment, and management strategies for adverse events related to bispecific antibodies., Discussion: Side effects related to BsAbs require a multidisciplinary treatment approach ideally with oncologists notified early when an adverse event is suspected. Symptom presentation is subtle with BsAb toxicity and the main adverse events to consider working up are cytokine release syndrome, immune effector cell neurotoxicity, and infection. The article also discusses unique side effects specific to FDA-approved drugs to treat leukemia, multiple myeloma, lymphoma, lung cancer, and melanoma given that this drug class has heterogeneous receptor-specific side effects., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Published by Elsevier Ltd.)

Patients with lung cancer are especially vulnerable to coronavirus disease 2019 (COVID-19) with a greater than sevenfold higher rate of becoming infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) COVID-19, a greater than threefold higher hospitalization rate with high complication rates, and an estimated case fatality rate of more than 30%. The reasons for the increased vulnerability are not known. In addition, beyond the direct impact of the pandemic on morbidity and mortality among patients with lung cancer, COVID-19, with its disruption of patient care, has also resulted in substantial impact on lung cancer screening and treatment/management.COVID-19 vaccines are safe and effective in people with lung cancer. On the basis of the available data, patients with lung cancer should continue their course of cancer treatment and get vaccinated against the SARS-CoV-2 virus. For unknown reasons, some patients with lung cancer mount poor antibody responses to vaccination. Thus, boosting vaccination seems urgently indicated in this subgroup of vulnerable patients with lung cancer. Nevertheless, many unanswered questions regarding vaccination in this population remain, including the magnitude, quality, and duration of antibody response and the role of innate and acquired cellular immunities for clinical protection. Additional important knowledge gaps also remain, including the following: how can we best protect patients with lung cancer from developing COVID-19, including managing care in patient with lung cancer and the home environment of patients with lung cancer; are there clinical/treatment demographics and tumor molecular demographics that affect severity of COVID-19 disease in patients with lung cancer; does anticancer treatment affect antibody production and protection; does SARS-CoV-2 infection affect the development/progression of lung cancer; and are special measures and vaccine strategies needed for patients with lung cancer as viral variants of concern emerge., (Copyright © 2021 International Association for the Study of Lung Cancer.
