    T cell infiltration in the tumour microenvironment (TME) is a prerequisite for sustained antitumour immune responses. However, identifying predictive biomarkers that quantify T cell infiltration and the presence of proinflammatory TMEs associated with immune-checkpoint inhibitor (ICI) response for clinical implementation has proved challenging. Here, we highlight a study that validates a T cell-to-stroma enrichment score generated from RNA sequencing data as a novel biomarker for ICI response in patients with urothelial carcinoma.

    The composition of the gut microbiota has emerged as a tumour-extrinsic factor that modulates response to immune-checkpoint inhibitors (ICIs), although the lack of consistency in microbiota signatures across studies has limited their value as reliable biomarkers. Herein, we discuss a recent study in which longitudinal microbiome profiling identified several taxa that are persistently enriched in patients with melanoma and a favourable response to ICIs.

    Patients with early stage hepatocellular carcinoma typically undergo resection, liver transplantation or local ablation; however, 30–50% will have disease recurrence at 3 years. The authors of this Review describe the tumour immune microenvironment and mechanism of action of immunotherapies, and discuss the available evidence from phase II/III trials of neoadjuvant and adjuvant treatment approaches in this setting.

    Increasing evidence indicates that signalling networks activated downstream of oncogenic alterations contribute fundamentally to cancer immune evasion, including by promoting the accumulation of regulatory T (Treg) cells and other immunosuppressive cells in the tumour microenvironment (TME). Herein, the authors discuss the mechanisms via which cancers engage Treg cells to evade antitumour immunity, as well as the characteristics of Treg cells in the TME and their roles in resistance to immune-checkpoint inhibitors. Considering these aspects, they propose the concept of ‘immuno-genomic cancer evolution’ for tumorigenesis and the related paradigm of ‘immuno-genomic precision medicine’, postulating that the specific characteristics of cancer, especially genetic profiles that correlate with particular immunosuppressive networks in the TME, are likely to inform individualized strategies for combining molecularly targeted agents with immunotherapies.

    Dendritic cells (DCs) are antigen-presenting cells that function at the interface between innate and adaptive immunity, thereby acting as key mediators of antitumour immune responses and immunotherapy efficacy. In this Review, the authors outline the emerging complexity of intratumoural DC states that is being revealed through single-cell analyses as well as the contributions of different DC subsets to anticancer immunity and the activity of immune-checkpoint inhibitors. The authors also discuss advances in the development of DC-based cancer therapies and considerations for their potential combination with other anticancer therapies.

    Durable responses with first-line platinum-based chemotherapy for advanced-stage urothelial carcinoma are rare, and patient outcomes are poor. Recently, CheckMate 901 became the first phase III trial to establish a significant overall survival benefit from a combined chemoimmunotherapy approach in this disease setting. Herein, we discuss key findings from CheckMate 901 and their implications in the context of a rapidly evolving treatment landscape.

  • Review Article |

    Despite dramatic progress over the past decade, only around 50% of patients with advanced-stage melanoma derive durable benefit from immune-checkpoint inhibitors (ICIs) and/or BRAF and MEK (BRAF/MEK) inhibitors. Over the past few years, adoptive cell therapy with tumour-infiltrating lymphocytes (TILs) has demonstrated encouraging efficacy including in patients with disease progression on ICIs or BRAF/MEK inhibitors. In this Review, the authors summarize the role of TIL therapies in the management of these patients and describe future research strategies that might improve safety or efficacy.

    Patients with advanced-stage urothelial cancer (aUC) continue to have poor long-term survival outcomes. However, developments in the past 5 years, most notably the availability of maintenance therapy with the anti-PD-1 antibody avelumab, are beginning to change this issue. In this Review, the authors provide an overview of the treatment of patients with aUC, including considerations of the various promising new therapeutic modalities and how they might improve clinical outcomes.

    Despite some success in patients with certain B cell malignancies and relapsed and/or refractory multiple myeloma, studies testing chimeric antigen receptor (CAR) T cells in patients with advanced-stage solid tumours have been largely unsuccessful, with a few notable exceptions. In this Perspective, the author provides some possible reasons for the failures of most CAR T cell-based approaches and suggests strategies that might address some of these challenges.

    The availability of regimens containing one or more immune-checkpoint inhibitors (ICIs) has improved the outcomes in patients with advanced-stage hepatocellular carcinoma. However, clinical benefit from these regimens is difficult to predict, indicating the need for novel biomarkers. In this Review, the authors describe the available evidence on biomarkers to guide the use of ICIs in these patients and discuss promising future research directions.

    Many studies attempting to identify biomarkers for predicting of immune-checkpoint inhibitor (ICI) efficacy have led to the description of Gut OncoMicrobiome Signatures (GOMS). Several GOMS support an association between oncogenesis and intestinal dysbiosis, and other GOMS are shared between patients with several cancer subtypes and individuals with seemingly unrelated chronic inflammatory disorders. The authors of this Review discuss these patterns as well as the findings from a meta-analysis of GOMS associated with clinical benefit from ICIs, and propose practical guidelines to incorporate GOMS in decision-making in immuno-oncology.

    COSMIC-313 combines all of the approved drugs against actionable targets in renal cell carcinoma into one triplet regimen. Although this approach has greater clinical efficacy than one of the standard-of-care doublet therapies, toxicities can limit adequate drug administration and, thus, we argue that this regimen should not yet be adopted. We also discuss ongoing investigations of other triplet regimens.

    Advances in technology have enabled the development of several novel antibody–drug conjugates (ADCs) with encouraging clinical activity in patients with advanced-stage solid tumours. Indications for these therapies are expanding rapidly to earlier lines of therapy. Nonetheless, the toxicities of these various agents are not trivial and can be fatal, even in patients with early stage disease. In this Review, the authors summarize the toxicities of ADCs in patients with solid tumours both as monotherapies and in combination with other agents and discuss various ongoing research efforts attempting to optimize the therapeutic index of these agents.

    Radiotherapy has several key attributes that make it an attractive combination partner for immunotherapy; however, numerous clinical trials investigating the combination of these two treatment modalities have failed to demonstrate clear improvements in patient outcomes. In this Review, Galluzzi and colleagues discuss the evidence indicating that radiotherapy administered according to standard schedules and target volumes might impair immune fitness and, therefore, propose that adaptation of the radiotherapy regimens to immunotherapy (and not vice versa) might synergistically enhance the antitumour immune response to achieve meaningful clinical benefits.

    Long-term survival rates of patients with gastric cancer remain low, particularly in Western countries. This lack of progress, among other aspects, is likely to reflect a focus on empirical approaches that fail to account for the heterogeneity of gastric cancers. In this Review, the authors summarize the available evidence on the management of patients with early stage gastric cancers, with an emphasis on understanding the underlying biology in order to improve the outcomes in patients with these historically difficult-to-treat tumours.

    Neoadjuvant immune-checkpoint inhibition is a promising emerging treatment strategy that potentially enables patients with a good response to initial therapy to avoid further treatment and the associated toxicity risks, while also identifying those who might require treatment escalation. In this Review, the authors describe treatment personalization strategies based on the initial response to one or more neoadjuvant immune-checkpoint inhibitors and consider the potential to expand this approach beyond patients with melanoma.

    Oesophageal cancer is one of the most common malignancies worldwide and is associated with considerable morbidity and mortality. In this Review, the authors highlight advances made across the disease continuum that have improved the management and outcomes of patients with oesophageal cancer. These advances include an increased understanding of the disease biology, improvements in screening, the development of minimally invasive endoscopic monitoring and management technologies, refinement of surgical techniques and perioperative management, and novel radiotherapy and systemic therapy approaches. Continual multidisciplinary efforts across all these aspects of care will further improve patient outcomes.

    Chimeric antigen receptor (CAR) T cells have dramatically improved the outcomes of patients with certain relapsed and/or refractory haematological malignancies. Owing to the promising short-term survival outcomes achieved, long-term data on both safety and survival are becoming increasingly relevant. In this Review, the authors describe the available long-term follow-up data from early studies testing the safety and efficacy of receiving CAR T cells targeting CD19 as well as more recent data on BCMA-targeted CAR T cells in patients with relapsed and/or refractory multiple myeloma.

    Plasma cell-free DNA analysis has emerged as a powerful liquid biopsy assay to assess circulating tumour DNA in response to cancer treatments. A new study shows that cell-free DNA can also inform on expansion kinetics and tumour-infiltration patterns in patients receiving chimeric antigen receptor T cells and, together with circulating tumour DNA, provides vivid prognostic insights into intratumoural dynamics.

    Data obtained using omics technologies can offer important insights into various aspects of chimeric antigen receptor (CAR) T cell therapy. In this Review, the authors provide an overview of the multidimensional profiling technologies that have been applied in investigations of CAR T cell therapy. They then discuss the ways in which multi-omics data obtained through such analyses can be used to elucidate CAR targets, factors associated with response or resistance to therapy, and mechanisms underlying the associated toxicities, which could potentially be exploited to improve the efficacy and safety of CAR T cell therapies.

    Immune-checkpoint inhibitors (ICI) constitute a paradigm shift in the treatment of non-small-cell lung cancer (NSCLC); however, identifying the minority of patients who derive long-term benefit remains problematic, particularly among those with targetable oncogenic drivers who have typically been under-represented in or excluded from clinical trials of ICIs. This Review summarizes the associations of common oncogenic drivers of NSCLC with sensitivity or resistance to ICIs as well as the underlying effects on the immune tumour microenvironment. Potential vulnerabilities that could potentially be exploited to overcome primary resistance to ICIs conferred by certain oncogenic drivers are also highlighted.

    Oncolytic viruses (OVs) provide a novel cancer treatment strategy, with a mechanism of action and toxicity profiles that are distinctly different to those of more traditional therapies. Thus far, four OVs have entered clinical use globally, yet only talimogene laherparepvec (T-VEC) has entered widespread clinical use. In this Review, the authors describe the clinical and regulatory experience with T-VEC thus far, and how this can guide the development of novel OVs. Discussions of a range of novel OVs with the potential for clinical implementation in the near future are also provided.

    γδ T cells are lymphocytes with properties of both typical αβ T cell and natural killer cells, notable tissue tropisms, and MHC-independent antitumour functions that make them attractive agents for cancer immunotherapy. In this Review, the authors provide an overview of human γδ T cell subsets, discuss the antitumour and pro-tumour activities of these cells and their prognostic value in patients with cancer, and describe the current landscape of γδ T cell-based immunotherapies.

    Immunotherapies have dramatically improved the outcomes of a subset of patients with advanced-stage cancers. Nonetheless, most patients will not respond to these agents and adverse events can be severe. In this Review, the authors describe the potential to address these challenges by combining immunotherapies with currently available thermal therapies as well as by using thermal immuno-nanomedicines.

    Although almost all patients with uveal melanoma have localized disease at diagnosis, and despite effective treatment of the primary tumour, metastatic recurrence is common and holds a dismal prognosis. Unlike its cutaneous counterpart, therapeutic advances for uveal melanoma have not been forthcoming, although the recent approval of the first systemic therapy for this disease has ushered in a new era of hope. This Review summarizes the biology of uveal melanoma and the management of primary disease, including molecular risk classification, adjuvant therapy and follow-up strategies. The discussion is then focused on the established and emerging regional and systemic treatments for metastatic uveal melanoma.

    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.
