ReviewDe-novo and acquired resistance to immune checkpoint targeting.
Use of immune checkpoint inhibitors targeting the programmed cell death protein-1/programmed cell death-ligand 1 and cytotoxic T lymphocyte-associated protein-4 axes has yielded impressive results in some clinical trials. However, only a subset of patients initially respond to these inhibitors, and increasing clinical evidence indicates that a substantial proportion of initial responders ultimately relapse with lethal, drug-resistant disease months or years later. ⋯ Cancer genomes bear signatures of clonal evolution and selection, particularly implicating acquired defects in interferon receptor signalling and antigen presentation. In this Review, we discuss the biological processes that operate in the formation of so-called immunoresistant niches, and describe the latest progress in the development of combination strategies to reinstate immunosurveillance in immune-refractory tumours.

Review Meta AnalysisIncomplete excision of cervical precancer as a predictor of treatment failure: a systematic review and meta-analysis.
Incomplete excision of cervical precancer is associated with therapeutic failure and is therefore considered as a quality indicator of clinical practice. Conversely, the risk of preterm birth is reported to correlate with size of cervical excision and therefore balancing the risk of adequate treatment with iatrogenic harm is challenging. We reviewed the literature with an aim to reveal whether incomplete excision, reflected by presence of precancerous tissue at the section margins, or post-treatment HPV testing are accurate predictors of treatment failure. ⋯ European Federation for Colposcopy and Institut national du Cancer (INCA).

Review Comparative StudyAn integrated multidisciplinary algorithm for the management of spinal metastases: an International Spine Oncology Consortium report.
Spinal metastases are becoming increasingly common because patients with metastatic disease are living longer. The close proximity of the spinal cord to the vertebral column limits many conventional therapeutic options that can otherwise be used to treat cancer. ⋯ In this Review, we discuss the variables that should be considered during the management of these patients and review the role of each discipline and their respective management options to provide optimal care. This work is synthesised into a practical algorithm to aid clinicians in the management of patients with spinal metastasis.

Lung cancer screening with low-dose CT can save lives. This European Union (EU) position statement presents the available evidence and the major issues that need to be addressed to ensure the successful implementation of low-dose CT lung cancer screening in Europe. ⋯ This position statement recommends the following actions: a risk stratification approach should be used for future lung cancer low-dose CT programmes; that individuals who enter screening programmes should be provided with information on the benefits and harms of screening, and smoking cessation should be offered to all current smokers; that management of detected solid nodules should use semi-automatically measured volume and volume-doubling time; that national quality assurance boards should be set up to oversee technical standards; that a lung nodule management pathway should be established and incorporated into clinical practice with a tailored screening approach; that non-calcified baseline lung nodules greater than 300 mm3, and new lung nodules greater than 200 mm3, should be managed in multidisciplinary teams according to this EU position statement recommendations to ensure that patients receive the most appropriate treatment; and planning for implementation of low-dose CT screening should start throughout Europe as soon as possible. European countries need to set a timeline for implementing lung cancer screening.
