Immune checkpoint inhibitors (ICIs) are antibodies that target key signalling pathways such as programmed death 1 (PD1)/programmed death-ligands 1 and 2 (PDL1 and PDL2) to improve anti-tumour immune responses. Until recently, nivolumab was the only ICI validated for advanced non-small-cell lung cancer (NSCLC) in a second-line treatment setting. Results from recent phase II and phase III randomised trials testing other ICIs have been presented. ⋯ An encouraging report of the efficacy of pembrolizumab in addition to CT in first-line treatment in unselected NSCLC was also presented (Keynote-021) with an ORR of 55% versus 29% with CT alone (P = 0.0016). Atezolizumab, an anti-PDL1 antibody, showed efficacy for second-line treatment compared with docetaxel (OAK phase III study) with an OS (median) of 13.8 months versus 9.6 months with docetaxel. These results suggest a new paradigm for the treatment of advanced NSCLC using pembrolizumab for the first-line treatment of PDL1 ≥ 50% tumours.

Volume-outcome relation in palliative systemic treatment of metastatic oesophagogastric cancer.
Palliative systemic therapy has been shown to improve survival in metastatic oesophagogastric cancer. Administration of palliative systemic therapy in metastatic oesophagogastric cancer varies between hospitals. We aimed to explore the association between the annual hospital volume of oesophagogastric cancer patients and survival. ⋯ Improved survival in patients undergoing palliative systemic therapy for oesophagogastric cancer was associated with treatment in high-volume treatment and surgical centres. Further research should be implemented to explore which specific factors of high-volume centres are associated with improved outcomes.
