    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.

    Copper is an essential trace element with inherent redox properties and fundamental roles in a diverse range of biological processes; therefore, maintaining copper homeostasis is crucial. In this Review, the authors discuss new insights into the mechanisms by which disrupted copper homeostasis contributes to tumour initiation and development, including the recently defined concepts of cuproplasia (copper-dependent cell growth and proliferation) and cuproptosis (a mitochondrial pathway of cell death triggered by excessive copper exposure). They also discuss potential strategies to exploit cuproplasia and cuproptosis for the treatment of cancer.

    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.

    Various BRAF alterations are found and function as oncogenic drivers across diverse cancer types. BRAF inhibitor-based therapy has improved outcomes for patients with cancers harbouring BRAFV600 mutations, although resistance develops in most, and the current inhibitors are not effective against other types of BRAF alterations. In this Review, the authors describe the mechanisms underlying oncogenic BRAF signalling, as well as pan-cancer and lineage-specific mechanisms of intrinsic, adaptive and acquired resistance to BRAF inhibitors. They also discuss novel RAF inhibitors and drug combinations designed to overcome these resistance mechanisms and/or expand the applicability of molecularly targeted therapy to a broader range of BRAF-mutant cancers.

    The discovery of ERBB2 as a gene frequently amplified and/or overexpressed in breast cancers and of its product HER2 as a biomarker has spurred the development of various targeted therapies. As a result, the prognosis of patients with advanced-stage HER2-positive breast cancer has greatly improved in the past decades. The authors of this Review describe the development of the current treatment landscape for these patients and discuss how to address resistance to further improve outcomes.

    The current standard-of-care adjuvant treatment for patients with colorectal cancer is chemotherapy selected on the basis of conventional histopathological staging criteria; however, the clinical benefit from these regimens is limited. The authors of this Perspective discuss strategies to minimize toxicity and monitor efficacy of these regimens, and propose new tools for disease staging that could enable more personalized treatment decisions.

    According to the precision oncology paradigm, cancer therapies are increasingly being matched to specific sensitizing alterations using a biomarker-directed approach. However, the criteria for determining the actionability of molecular alterations and selecting matched treatments evolve over time. Molecular tumour boards (MTBs) have emerged as means to capitalize on the collective knowledge of various experts to interpret molecular-profiling data and to eliminate subjectivity in treatment selection. This Review describes the components, processes and increasingly important role of MTBs in optimizing the implementation of precision oncology in both clinical trials and clinical practice, as well as current and future considerations for ensuring the sustainability of MTBs and expanding their outreach to underserved populations.

    Despite improved effectiveness, most systemic cancer therapies are not curative and most patients will develop acquired resistance that often cannot be explained by the emergence of specific genomic alterations. In this Perspective, the authors describe the potential role of a small population of tumour cells, termed drug-tolerant persister cells, that are able to survive therapy and, on continued treatment exposure, develop stable mechanisms of resistance to systemic therapies.

    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.

    Despite improved outcomes owing to advances in systemic targeted therapies, patients with brain metastases from oncogene-driven non-small-cell lung cancer continue to have a poor prognosis. This situation largely reflects the limited central nervous system (CNS) penetrance of most targeted therapies, a limitation that is beginning to be addressed with the development of later-generation agents. In this Review, the authors describe the CNS activity of targeted therapies for patients with oncogene-driven non-small-cell lung cancers, including discussions of novel agents with improved CNS penetrance and the potential of intrathecal administration for patients with leptomeningeal disease.

    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.

    The authors of this Perspective propose that, with further improvement in detection efficiency, circulating tumour cells (CTCs), which are released early during cancer development, have the potential to be used for the early detection of clinically relevant, aggressive cancers. Thus, use of CTCs as diagnostic biomarkers might improve outcomes by enabling the identification of cancers at a stage at which they are more amenable to treatment while avoiding overtreatment of patients with indolent tumours.

    Emerging data indicate a central role for the microbiota in all aspects of colorectal cancer (CRC). Despite this general consensus, understanding the role of specific components of the microbiota in such a way that enables the development of clinical interventions or tools to inform clinical decision-making has thus far proved challenging. In this Review, the authors summarize the role of the microbiota in CRC, including in prevention, in interactions with treatment and as a source of novel biomarkers.

    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.

    Lung cancers harbouring ‘rare’ alterations (defined as those with a prevalence of <5% of oncogene-driven lung cancers) can be detected in around a third of all oncogene-driven lung cancers and are diagnosed in thousands of patients each year. Advances in our understanding of tumour biology, diagnosis and the development of novel therapies are enabling increasing use of specific therapies targeting these alterations. In this Review, the authors provide an overview of the epidemiology, diagnosis, prognosis and treatment of patients with lung cancers harbouring these rare alterations. The importance of expedited drug approval pathways and cooperation between multiple stakeholders is also emphasized.

    The revolution of immunotherapies in oncology has not been matched by the development of companion diagnostic biomarkers able to identify the ideal target populations. Aside from the established pathways for regulatory approval relying on predefined biomarkers, a novel approach based on post hoc biomarker analysis could potentially be instrumental in enhancing the cost-effectiveness of cancer immunotherapy.

    PADA-1 is the first trial to demonstrate benefit from a treatment-switching strategy guided by active monitoring of ESR1 mutations in plasma circulating tumour DNA (ctDNA) from patients with breast cancer. The results of this trial raise important questions about the specific treatment approach tested, and the feasibility of trials incorporating longitudinal ctDNA analyses to anticipate resistance and guide treatment.

    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.

    Advances in circulating tumour DNA (ctDNA) detection and analysis are beginning to be implemented in clinical practice. Nonetheless, much of this development has thus far focused on plasma ctDNA. Theoretically, all bodily fluids, including urine, cerebrospinal fluid, saliva, pleural fluid and others, can also contain measurable ctDNA and can provide several advantages over the reliance on plasma ctDNA. In this Review, Tivey et al. describe the potential roles of ctDNA obtained from non-plasma sources in optimizing the outcomes of patients with cancer.

    The oligometastatic state is generally considered to constitute an intermediate point along the spectrum of cancer dissemination at which the metastatic burden is limited and local ablative therapies can result in meaningful clinical benefit, and possibly even cure. In this Review, Katipally et al. reframe the oligometastatic phenotype as a dynamic state that expands beyond merely the number or size of metastases. They highlight important risk factors defining the metastatic spectrum that can inform both staging and therapy, and identify themes in the literature that might guide strategies to optimally combine metastasis-directed local therapies with modern systemic treatments.

    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.

    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.

    Circular RNAs (circRNAs) are a novel class of primarily non-coding RNAs with increasingly recognized roles in cancer development and progression through diverse mechanisms of action. Herein, the authors review the current understanding of circRNA biogenesis, regulation, physiological functions and pathophysiological roles in cancer. They also discuss the clinical potential of circRNAs as biomarkers, therapeutic agents and drug targets in oncology as well as research controversies, technical issues and biological knowledge gaps that need to be addressed before this promise can be realized.

    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.

    PD-L1 expression is currently the best available biomarker for the prediction of responsiveness to immune-checkpoint inhibitors. However, several immunohistochemical assays are now approved for clinical use in various settings, despite imperfect inter-assay concordance, with important implications for pathology services and, potentially, for clinical outcomes. In this Review, the authors compare the performance of the various FDA-approved PD-L1 assays, discuss the varying implications of PD-L1 expression across different tumour types and provide guidance on possible novel approaches that might optimize the clinical utility of PD-L1 as a biomarker.
