A real-world study of 145 resectable NSCLC patients who achieved pathological complete response after neoadjuvant chemoimmunotherapy found no significant disease-free or overall survival benefit from adding adjuvant immunotherapy. The findings suggest that patients with a pCR may not need further postoperative treatment, though larger prospective studies are required for confirmation.
A research team led by Prof. Yi Sun at Zhejiang University, reported a unexpected finding that the combination of KrasG12D activation and genetic inactivation of UBE2M in the lung triggers the cGAS-STING-NF-κB signal to form a inflammatory tumor microenvironment (TME). Mechnistically, KrasG12D promotes the mitochondrial biogenesis, whereas UBE2M depletion inhibits Parkin neddylation and mitophagy, together causing the cytoplasmic release of damaged mitochondrial DNA. The STING antagonist H-151 rescues TME, indicating a causal role of the cGAS-STING signal. The study therefore demonstrates a unexpected role of UBE2M in prevention TME induced by Kras mutant.
As a new member of BLOODPAC, a leading international consortium on liquid biopsy, the Josep Carreras Leukaemia Research Institute will contribute to advancing liquid biopsy research and developing standards and validation protocols, with the aim of bringing this knowledge back to the Catalan and Spanish health system.
The Josep Carreras Institute becomes the first Spanish institution to become part of this prominent international consortium, contributing its expertise in blood cancers research to a global network of academic, industry and regulatory stakeholders.
