Reviews & Analysis

Oncolytic viruses (OVs) provide a novel cancer treatment strategy, with a mechanism of action and toxicity profiles that are distinctly different to those of more traditional therapies. Thus far, four OVs have entered clinical use globally, yet only talimogene laherparepvec (T-VEC) has entered widespread clinical use. In this Review, the authors describe the clinical and regulatory experience with T-VEC thus far, and how this can guide the development of novel OVs. Discussions of a range of novel OVs with the potential for clinical implementation in the near future are also provided.

New genetic analyses demonstrate that the presence of low-frequency subclonal populations, including high-risk subclones, at diagnosis in multiple myeloma can contribute to disease relapse and poor clinical outcomes. Thus, sensitive detection approaches are required to detect these subclones at diagnosis together with innovative treatment strategies to eradicate low-frequency, high-risk subclones and prevent them from becoming dominant.

γδ T cells are lymphocytes with properties of both typical αβ T cell and natural killer cells, notable tissue tropisms, and MHC-independent antitumour functions that make them attractive agents for cancer immunotherapy. In this Review, the authors provide an overview of human γδ T cell subsets, discuss the antitumour and pro-tumour activities of these cells and their prognostic value in patients with cancer, and describe the current landscape of γδ T cell-based immunotherapies.

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 almost all patients with uveal melanoma have localized disease at diagnosis, and despite effective treatment of the primary tumour, metastatic recurrence is common and holds a dismal prognosis. Unlike its cutaneous counterpart, therapeutic advances for uveal melanoma have not been forthcoming, although the recent approval of the first systemic therapy for this disease has ushered in a new era of hope. This Review summarizes the biology of uveal melanoma and the management of primary disease, including molecular risk classification, adjuvant therapy and follow-up strategies. The discussion is then focused on the established and emerging regional and systemic treatments for metastatic uveal melanoma.
