Treatment with the ROS1 inhibitor entrectinib yielded deep and durable responses in patients with ROS1 fusion-positive non–small cell lung cancer (ROS1+ NSCLC), including in those with brain metastases, according to a pooled analysis of three studies.
First-line therapy with the anti-programmed death ligand-1 (PD-L1) monoclonal antibody durvalumab improved overall survival (OS) in patients with metastatic non-small-cell lung cancer (NSCLC) compared with platinum-based chemotherapy (CT), according to results from two analyses of the MYSTIC* trial presented at ELCC 2019.
Maintenance immunotherapy with the immune checkpoint inhibitors nivolumab and ipilimumab failed to improve overall survival (OS) in individuals with extensive-stage disease small-cell lung cancer (ED-SCLC), according to CheckMate 451* results presented at ELCC 2019.

Macrolide antibiotics are derived from the Streptomycesspecies. These contain either 14-membered (erythromycin [ERM],clarithromycin [CAM], roxithromycin [RXM]), 15-membered(azithromycin [AZM]) or 16-membered (spiramycin, josamycin,midecamycin) macrocyclic lactone rings. They inhibit proteinsynthesis by reversibly binding to the 23S ribosomal RNA (rRNA)in the 50s subunit of the bacterial ribosome. Traditionally,macrolides are used as first-line agents in respiratory, skin,soft tissue, and urogenital infections, and they are also activeagainst gram-positive cocci and atypical pathogens.
Nonsmall cell lung cancer (NSCLC) patients harbouring sensitive EGFR mutations may fare well with the third-generation tyrosine kinase inhibitor osimertinib as an upfront therapy, with the results of a network meta-analysis showing that the drug tops other currently available options in terms of progression-free survival and tolerability.
Pneumonia is a common infection– affecting around 3,200 people inSingapore in 2016 – making it the thirdmost common cause of hospitalisation inthe country. Its common complications,especially with delayed or inappropriatetreatment, include bacteraemia andseptic shock, lung abscesses, pleuraleffusions, empyema, pleurisy, respiratoryfailure and renal failure.
