In oncology, mRNA–lipid nanoparticles (LNPs) have been used either to achieve intratumoural expression of immune-stimulating cytokine combinations or as cancer vaccines, and new strategies are in development to enable the selective delivery of payloads into cancer cells previously considered unreachable. The authors of this Review present various approaches for delivering mRNA–LNPs to tumours and discuss improvements that will improve the selective targeting of cancer cells with mRNA–LNPs.

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.

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 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.

Projected increases of cancer-attributable health-care costs, accompanied by staff shortages, will impose future economic and operational challenges on national health-care systems. Herein, we highlight a series of clinical and health economic rationales in support of publicly funded clinical trial teams that conduct real-world dose-reduction trials aiming for adjustment of cancer drug label doses to reduce not only the financial burden on payers, but also the toxicity burden on patients.
