    The first phase III trial to test perioperative immune-checkpoint inhibitor therapy for high-risk renal cell carcinoma yielded highly promising results, leading to regulatory approvals of adjuvant pembrolizumab. However, subsequent phase III trials, including the IMmotion010 trial of adjuvant atezolizumab, did not demonstrate similar benefits. Although molecular biomarkers are urgently needed to better delineate responder subgroups, the unique design of each trial might partially explain some of the patterns identified.

    Chimeric antigen receptor (CAR) T cells are effective therapies for patients with relapsed and/or refractory B cell malignancies, partly owing to the ability to target B cell-specific antigens. However, CAR T cells targeting solid tumour antigens are likely to carry a higher risk of on-target, off-tumour toxicity (OTOT). Here, the authors summarize the available data on OTOT in the context of CAR T cells targeting solid tumour antigens and describe novel CAR T cell designs that might overcome such toxicities.

    Owing to several limitations, including elimination by the immune system and a lack of tumour specificity, systemically administered synthetic nanoparticles are used for a limited range of cancer indications. In this Review, the authors describe the potential of cellular nanoparticles (comprising a cell membrane coating around a synthetic core) to overcome these issues as well as their application in drug delivery, phototherapy and immunotherapy.

    A high tumour mutational burden (≥10 mutations per megabase) is a companion biomarker in the histology-agnostic approval of pembrolizumab for treatment-refractory advanced-stage solid tumours, and continues to be an exploratory predictive biomarker for immune-checkpoint inhibitors in non-small-cell lung cancer. Herein, we discuss recent results from the first phase III trial evaluating blood-based tumour mutational burden in patients with treatment-naive advanced-stage non-small-cell lung cancer.

    Immune-checkpoint inhibitors have revolutionized the treatment of patients with non-small-cell lung cancer (NSCLC). Recently, indications for immune-checkpoint inhibitors have expanded from advanced-stage NSCLC to adjuvant, and now neoadjuvant, therapy for resectable NSCLC, with three cycles of preoperative chemoimmunotherapy achieving superior pathological complete response rates and event-free survival compared with chemotherapy alone in the phase III CheckMate 816 trial.

    Immune-checkpoint inhibitors and BRAF-targeted therapy have revolutionized the treatment of advanced-stage, unresectable melanoma and have been successfully transitioned into the resectable disease setting as (neo)adjuvant treatments. The expanding range of treatment options available for resectable high-risk melanoma raises questions over selection of the optimal therapeutic strategy and agents for each individual. Furthermore, the use of perioperative therapy has potentially important implications for the management of patients who have disease recurrence. In this Viewpoint, we asked four expert investigators who have been involved in the key studies of perioperative systemic therapies for their perspectives on the optimal management of patients with high-risk melanoma.

    Two recent large-cohort studies reinforce the potential predictive capability of gut microbiota for immune-checkpoint inhibitor response and toxicities in patients with melanoma. However, additional investigations are required to understand the mechanistic underpinnings of this complex multifaceted relationship, and how it can be exploited for personalized cancer care.

    The tumour microenvironment includes various diverse immune cell types, each of which might influence tumour progression and response to treatment, particularly with immunotherapies. These cell types include different subtypes of B lymphocytes, which are often associated with tertiary lymphoid structures (TLS) and can have pro-tumour or anti-tumour effects, either through their classical function in antibody production and antigen presentation or other mechanisms. Herein, Fridman et al. discuss the phenotypic heterogeneity of intratumoural B cells and the importance of TLS in their generation, the potential of B cells and TLS as prognostic and/or predictive biomarkers, and novel approaches aiming to enhance the development of TLS and anti-tumour B cells for cancer therapy.

    The interaction of tumour-associated macrophages (TAMs) with cancer and stromal cells in the tumour microenvironment enables and sustains most of the hallmarks of cancer. The authors of this Review examine the diversity of TAMs in various cancer indications, which is being revisited with the advent of single-cell technologies, and discuss the functional roles of different TAM states, the prognostic and predictive value of TAM-related signatures as well as approaches involving TAMs that are currently being or will soon be tested in clinical trials.

    Chimeric antigen receptor T cells have revolutionized the treatment of patients with certain haematological malignancies. Nonetheless, an optimal approach to lymphodepleting chemotherapy and/or bridging therapies has yet to be defined in patients receiving these agents. In this Review, the authors describe the various lymphodepletion and/or bridging therapy strategies used, and highlight the need for prospective comparisons in order to determine the safest and most effective approach.

    Immune-checkpoint inhibitors (ICIs) have dramatically improved the outcomes of patients with advanced-stage solid tumours, including the potential for long-term remission in a subset. However, long-term follow-up data reveal a risk of chronic toxicities from these agents, which can have important quality-of-life implications. In this Review, the authors describe the current level of evidence of chronic toxicities of ICIs and their implications for patients

    Immune-checkpoint inhibitors are associated with a unique spectrum of organ-specific inflammatory toxicities known as immune-related adverse events (irAEs). In the past few years, aggregate clinical data, real-world data and multi-omics data have been used to investigate the underlying mechanisms and clinical presentations of irAEs. The authors of this Perspective summarize the knowledge on irAEs that has been obtained from different sources of ‘big data’.

    A variety of cytokines have diverse antitumour and/or pro-tumour activities and, accordingly, alterations in cytokine networks contribute to cancer development and progression. Therefore, cytokines and their receptors have long been investigated as therapeutic agents or targets in oncology, although with mostly disappointing results. Herein, Propper and Balkwill discuss the lessons learnt from initial clinical trials of monotherapy approaches as well as subsequent strategies to better leverage cytokines and cytokine antagonists in the treatment of solid tumours.

    Efforts are being made to incorporate immune-checkpoint inhibitors into therapy for early stage non-small-cell lung cancer. The IMpower010 trial of adjuvant atezolizumab has recently become the first study to demonstrate that this strategy can improve disease-free survival in a subset of patients. This trial opens a new area of research in the quest for the optimal perioperative strategy to increase overall survival.

    A high tumour burden has long been associated with inferior outcomes on traditional cancer therapies and emerging evidence suggests that tumour burden is particularly relevant for patients receiving immune-checkpoint inhibitors. Here, the authors summarize the available clinical and preclinical evidence for the role of tumour burden in determining the outcomes of patients receiving immune-checkpoint inhibitors and highlight areas that are likely to be of future research interest in this emerging area.

    Chimeric antigen receptor (CAR) T cells have remarkable efficacy in patients with B cell acute lymphoblastic leukaemia (ALL), but have not been successful to date in patients with T cell ALL (T-ALL). Now, data from Pan and colleagues demonstrate the safety and impressive short-term efficacy of allogeneic donor-derived anti-CD7 CAR T cells in an early-phase clinical trial involving patients with relapsed and/or refractory T-ALL.

    Immune-checkpoint inhibitors have dramatically improved the outcomes in patients with advanced-stage cancers, although the majority of patients will not respond to these agents. Here, the authors describe the potential of targeting emerging immunomodulatory pathways, with a focus on alternative immune checkpoints and tumour metabolism as approaches that might enable further improvements in the outcomes of patients with cancer, either as monotherapies or in combination with existing agents.

    Two recent studies addressed the functional properties and clinical significance of tumour antigen-specific effector T cells in human melanomas and lung carcinomas using single-cell strategies. Herein, we discuss their findings, which expand our understanding of T cell alterations in the tumour microenvironment and demonstrate that CD8+ T cell exhaustion is mediated by exposure to tumour cell-specific antigens and is associated with a tissue-resident memory phenotype.

    Chimeric antigen receptor (CAR) T cell therapies are generating substantial excitement and have been approved for the treatment of various haematological malignancies. All approved CARs consist of an extracellular antigen-binding domain linked to an intracellular region containing a costimulatory domain and a T cell activation domain. A key question is whether the CD28-derived and 4-1BB-derived costimulatory domains used in current commercial CAR T cell products are associated with different cellular and clinical effects. Herein, Cappell and Kochenderfer provide an overview of CD28 and 4-1BB costimulatory pathways and compare the outcomes observed in preclinical and clinical studies with CARs incorporating either costimulatory domain.
