Adjuvant ipilimumab is associated with an 11% improvement in 5-year overall survival in patients with high-risk melanoma, but at the cost of considerable toxicity, with half of patients discontinuing treatment owing to adverse events. An analysis of quality-of-life (QoL) outcomes, however, showed little impact of adverse effects of this treatment on QoL, which is puzzling.

The Cancer Genome Atlas Research Network recently published the most comprehensive, multi-omic molecular characterization of cervical cancers performed to date. The data reveal novel disease subtypes, and provide new insights into the aetiology and pathogenesis of cervical cancer. Importantly, the information obtained has potentially major clinical implications.

Tumour-associated macrophages (TAMs) are key drivers of tumour-promoting inflammation and cancer progression, and are important determinants of responsiveness to a range of therapies. Herein, the authors summarize the roles of TAMs in cancer, and discuss the potential of TAM-targeted therapeutic strategies to complement and synergize with other anticancer treatments.

By preventing the accumulation of misfolded or damaged proteins, the ubiquitin-proteasome pathway has essential functions in cell homeostasis. Cancer cells produce proteins that promote cell survival and proliferation, and inhibit cell death, and thus, clinical trials have tested the therapeutic effect of proteasome inhibitors on patients with a variety of cancer types, mainly haematological malignancies. Herein, the authors discuss the advances and challenges derived from the introduction of proteasome inhibitors in the clinic, including therapeutic resistance.

In 2016, a revised WHO classification of glioma was published, in which molecular data and traditional histological information are incorporated into integrated diagnoses. Herein, the authors highlight the developments in our understanding of the molecular genetics of gliomas that underlie this classification, and review the current landscape of molecular biomarkers used in the classification of disease subtypes. In addition, they discuss how these advances can promote the development of novel pathogenesis-based therapeutic approaches, paving the way to precision medicine.
