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).

Multicenter StudyLorlatinib in non-small-cell lung cancer with ALK or ROS1 rearrangement: an international, multicentre, open-label, single-arm first-in-man phase 1 trial.
Most patients with anaplastic lymphoma kinase (ALK)-rearranged or ROS proto-oncogene 1 (ROS1)-rearranged non-small-cell lung cancer (NSCLC) are sensitive to tyrosine kinase inhibitor (TKI) therapy, but resistance invariably develops, commonly within the CNS. This study aimed to analyse the safety, efficacy, and pharmacokinetic properties of lorlatinib, a novel, highly potent, selective, and brain-penetrant ALK and ROS1 TKI with preclinical activity against most known resistance mutations, in patients with advanced ALK-positive or ROS1-positive NSCLC. ⋯ Pfizer.

Randomized Controlled Trial Multicenter StudyHealth-related quality-of-life results for pembrolizumab versus chemotherapy in advanced, PD-L1-positive NSCLC (KEYNOTE-024): a multicentre, international, randomised, open-label phase 3 trial.
In the phase 3 KEYNOTE-024 trial, treatment with pembrolizumab conferred longer progression-free survival than did platinum-based therapy in patients with treatment-naive, advanced non-small-cell lung cancer (NSCLC) with a programmed cell death-ligand 1 (PD-L1) tumour proportion score of 50% or greater (PD-L1-positive). Here we report the prespecified exploratory endpoint of pembrolizumab versus chemotherapy on patient-reported outcomes (PROs). ⋯ Merck & Co.

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.
