As more patients with oncogene-driven non-small-cell lung cancer are treated with targeted therapies, they are joining forces online to form groups that provide support, education and advocacy focused on specific oncogenes. Herein, we discuss how the involvement of these groups in patient-partnered research can benefit both patients and lung cancer research.

Chimeric antigen receptor (CAR) T cell therapy, the first approved therapeutic approach with a genetic engineering component, holds substantial promise in the treatment of a range of cancers but is nevertheless limited by various challenges, including toxicities, intrinsic and acquired resistance mechanisms, and manufacturing issues. In this Review, the authors describe the innovative approaches to the engineering of CAR T cell products that are providing solutions to these challenges and therefore have the potential to considerably improve the safety and effectiveness of treatment.

Numerous neoepitope-based vaccination strategies are in testing for clinical use in the treatment of cancer. Rapid identification of immunostimulatory neoantigen targets hastens neoantigen vaccine development. Papers recently published in Nature Biotechnology describe two independent machine-learning-based algorithms that demonstrate improved identification of MHC class II-binding peptides. Herein, we outline the benefits of these algorithms and their implications for future immunotherapies.

HER2-targeted therapy has greatly improved the outcomes of patients with HER2-positive breast cancer, with a range of agents now approved or in late-stage clinical development. In the era of precision medicine, efforts are being made to further improve patient outcomes by personalizing HER2-targeted treatment regimens, primarily though escalation or de-escalation of therapy according to the disease biology. In this Review, the authors provide an overview of the current landscape of HER2-targeted therapy and discuss the evidence supporting such tailored therapeutic strategies.

Shortages of drugs, including chemotherapeutics, are increasingly common in the USA, and compromise patient care, delay clinical trials and are associated with substantial financial costs. The recent shortage of vincristine, a chemotherapeutic used for most children with cancer and countless adult patients, presents a particularly vexing challenge. Drug shortages can cause patients unnecessary anxiety and challenge clinicians to ration lifesaving medications for which no alternative agent exists. We provide an overview of this problem and discuss potential solutions.

Cancer stem cells (CSCs) are implicated in cancer development, progression and resistance to treatment; therefore, the signalling pathways that mediate the CSC phenotype are attractive therapeutic targets. In this Review, the authors provide an update on the progress in targeting the Notch, WNT, Hedgehog and Hippo signalling pathways. Additionally, they discuss the interactions of CSCs with the immune system, the roles of CSC-related signalling pathways in immune cells and novel approaches to CSC-directed immunotherapy.

The identification of biomarkers and the development of genomics-based assays predictive of outcomes following radiotherapy, in an effort to help guide the treatment of patients with cancer, is an area of increasing research interest. Here, we discuss the validity of one such classifier, ARTIC, in the context of complementary genomic approaches designed to predict both tumour response and the susceptibility of nonmalignant tissues to toxicities resulting from radiotherapy.

Systemic hormone therapies and chemotherapy are the cornerstones of treatment for patients with de novo metastatic prostate cancer, with a currently limited role for local treatments. Herein, the authors outline the pathobiological and immunological rationale for local cytoreductive treatment of the primary tumour and/or metastases in patients with this disease. They also review the preclinical and clinical evidence for the use of radical prostatectomy, prostate radiotherapy, minimally invasive ablative therapies, and metastasis-directed therapy (predominantly with stereotactic ablative radiotherapy) in this population.

Virtually all patients with resectable pancreatic ductal adenocarcinoma (PDAC) will have disease progression, which is generally associated with dismal outcomes. However, novel targeted therapies and immunotherapies, selected based on the genomic and/or clinical features of patients’ tumours are beginning to improve the outcomes in subsets of patients. In this Review, the authors describe progress in novel therapies for patients with PDAC.
