Reviews & Analysis

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.

Immune-checkpoint inhibitors (ICIs) and other immunotherapies have revolutionized the treatment of patients with cancer. Nonetheless, most patients do not derive durable benefit, indicating a need for biomarkers to guide treatment selection. In this Review, the authors describe the role of antigen presentation in response to ICIs and other immunotherapies, with a focus on the role of molecular and/or genomic alterations affecting antigen presentation.

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.

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.

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.

The effective management of treatment-related events remains an unmet need in oncology. The authors of this Review discuss the underlying biological mechanisms, risk factors, most commonly used pharmacological and non-pharmacological management strategies, and clinical practice guidelines for the most common long-term (continuing beyond treatment) and late or delayed (following treatment) adverse events associated with chemotherapy and other anticancer treatments.

Dysregulation of N⁶-methyladenosine (m⁶A), the most prevalent internal modification in eukaryotic mRNA, is common in various cancer types. The authors of this Review provide an overview of the mechanisms of m⁶A-dependent RNA regulation, summarize current knowledge of their pathological effects and potential utility as biomarkers in cancer, and describe ongoing efforts to develop small-molecule inhibitors of oncogenic m⁶A modifiers.

Cholangiocarcinoma is a malignancy that continues to be associated with a dismal prognosis, and a better understanding of the disease biology is required to improve early detection and treatment strategies. In this Review, the authors describe key scientific and clinical advances made in this area over the past 5 years, encompassing novel insights into the tumour stroma and immune microenvironment, promising progress in developing liquid biopsy approaches for diagnosis and monitoring, clinical translation of molecularly targeted therapies, emerging immunotherapies and reassessment of the potential role of liver transplantation.

Bispecific T cell engagers offer a novel treatment approach for patients with multiple myeloma, although mechanisms of resistance are largely unknown. Here, we discuss the implications of a recent report from Friedrich et al. that highlights the importance of pre-treatment T cell characteristics for a response to the T cell engager elranatamab and how these data might be used to inform future study and trial design.

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.

Antibody–drug conjugates (ADCs) have demonstrated efficacy in patients with various cancers, although their antitumour activity in the central nervous system (CNS) might be limited by the blood–brain barrier. In this Review, the authors describe the available clinical data emphasizing the heterogeneous activity of ADCs against primary or secondary brain tumours and ongoing clinical trials in this area. In addition, they discuss physical, biological and molecular determinants of the CNS activity of ADCs, as well as potential strategies to improve delivery of these agents to brain tumours.

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.

Immune-checkpoint-inhibitor-associated myocarditis has a high fatality rate, warranting the development of more-effective treatment strategies. Herein, we discuss a recent report of a series of patients who were managed using a novel approach that involved personalized abatacept dosing, ruxolitinib and close respiratory monitoring, which was associated with low mortality.

Globally, gastric cancer is a common and highly fatal cancer with two anatomical subtypes, non-cardia and cardia gastric cancer. Helicobacter pylori causes almost 90% of distal gastric cancers worldwide. The authors of this Review summarize the current epidemiology of gastric cancer and the evidence and implications of primary and secondary prevention efforts.

Advances in surgical technique and chemotherapy regimens have improved the survival outcomes of patients with pancreatic cancer, although these remain dismal relative to most other solid tumours. Attempts to further improve outcomes have led to increasing research interest in neoadjuvant therapy, which is beginning to improve the outcomes of certain subgroups of patients. In this Review, the authors provide an overview of the various neoadjuvant therapy approaches for patients with pancreatic cancer, including discussions of several promising future research directions

Allele-specific inhibitors of KRAS^G12C are approved in non-small-cell lung cancer. Herein, we discuss recent results from the phase I/II KRYSTAL-1 trial of adagrasib alone and in combination with cetuximab in patients with KRAS^G12C-mutant metastatic colorectal cancer. The combination had promising efficacy and, if confirmed in later-phase trials, concomitant inhibition of EGFR and KRAS^G12C will present a new paradigm in precision oncology.

Bladder cancer is among the ten most common cancers worldwide and therefore constitutes a substantial health-care burden. This Review summarizes the global trends in bladder cancer incidence and mortality, and describes the main risk factors associated with bladder cancer occurrence and outcomes. The implications, challenges and opportunities of these epidemiological trends for public health and clinical practice are also discussed.
