    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.

    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 TAM (TYRO3, AXL and MERTK) family receptor tyrosine kinases (RTKs) have diverse cancer-promoting functions in malignant cells as well as immune cells and other cell types in the tumour microenvironment, presenting an attractive opportunity for both direct and immune-mediated therapeutic activity manifest through inhibition of a single target. Accordingly, a variety of agents designed to selectively target TAM RTKs are entering clinical testing. This Review provides an essential guide to the TAM RTKs for clinicians. The authors comprehensively review the various roles of TAM RTKs in cancer, the evidence supporting their potential as therapeutic targets, and the translational development of TAM-targeted agents as cancer treatments.

    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.

    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.

    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 radiotherapy affects multiple cellular pathways, treatments are generally planned with the assumption that all tumours respond similarly to radiation. The authors of this Review summarize the effect of various pathways activated by radiotherapy on tumour responses to radiotherapy and present the current knowledge on genomic classifiers designed to inform treatment decisions.

    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.

    Data on a new treatment approach utilizing bispecific monoclonal antibodies targetting B-cell maturation antigen (BCMA) were recently published, yielding very encouraging results in the setting of relapsed and/or refractory multiple myeloma (RRMM). How to safely and effectively deliver this treatment to patients and where it fits in the RRMM treatment paradigm are important questions for the future.

    Patients with non-small-cell lung cancers (NSCLCs) harbouring oncogenic EGFR or ALK alterations can benefit from therapies targeting these alterations, although acquired resistance to these agents is common. Third-generation inhibitors have extended the response durations of many patients with NSCLCs harbouring these alterations, albeit with differing patterns of resistance to those associated with earlier-generation agents. Here, the authors describe the mechanisms of acquired resistance to third-generation EGFR and ALK inhibitors and provide insights into future research directions in this area.

    Several PI3K pathway inhibitors are currently approved as cancer treatments; however, finding an acceptable therapeutic window to target this key signalling cascade linking cancer growth with metabolism has proven challenging and the clinical results to date have arguably been disappointing. In this Review, Vasan and Cantley discuss the effects of PI3K pathway alterations on signalling and metabolism in solid tumours as well as past and present efforts to improve the somewhat limited clinical efficacy of PI3K pathway inhibitors, with a particular focus on PI3Kα in breast cancers.

    Poly(ADP-ribose) polymerase (PARP) inhibitors are approved for patients with several forms of cancer, predominantly those harbouring loss-of-function BRCA1/2 mutations or other homologous recombination defects. Nonetheless, most patients receiving PARP inhibitors will ultimately develop resistance to PARP inhibitors, resulting in disease progression. In this Review, the authors describe the mechanisms of resistance to PARP inhibitors and discuss the potential treatment strategies that might overcome these effects.

    Patients with primary central nervous system (CNS) malignancies largely do not derive benefit from immune-checkpoint inhibitors. Paradoxically, a subset of those with CNS metastases from tumours located outside of the CNS will respond to the same approach. In this Perspective, the authors explore the key differences in the immune cell composition of primary CNS malignancies and brain metastases and provide guidance on potential alternative immunotherapies that might be effective in patients with these historically difficult-to-treat malignancies.

    Nuclear import and export proteins, such as exportin 1(XPO1), regulate the transport of proteins and other molecules into and out of the nucleus, including several tumour suppressor proteins. The dysregulation of nuclear export can be observed in several types of haematological and solid tumours, providing a rationale for a novel form of targeted therapy. In this Review, the authors describe the development of XPO1 inhibitors, from basic research to clinical approval.

    Despite several major therapeutic advances, multiple myeloma (MM) remains largely incurable, indicating a need for novel therapies. Thus, considerable research interest exists in chimeric antigen receptor (CAR) T cells targeting BCMA, which is almost universally expressed on MM cells. In this Review, the authors describe the clinical experience with anti-BCMA CAR T cells and discuss several new directions of future research that might prolong the responses of patients receiving these therapies.

    Most systemic cancer therapies are administered at doses at or close to the maximum tolerated dose until disease progression. However, this approach usually leads to treatment resistance and fails to take into account several potentially relevant evolutionary principles. In this Review, the authors describe how existing approaches to cancer therapy might be optimized by incorporating an understanding of evolutionary dynamics into cancer therapy.
