Island ecological restoration and management practices based on nature: Conference report.

As a result of climate change as well as the increasing need for island ecological protection, nature-based solutions have attracted increasing international attention. The impact of climate change and COVID-19 has presented island countries and regions with practical challenges such as rising sea levels, stunted economic development and difficult survival situations. Therefore, finding ways to realize the sustainable development of islands from a nature-based perspective has become a key concern. The Island Research Center of the Ministry of Natural Resources of China etc. organized the International Forum on Island Ecological Protection 2021 on November 19, 2021 with the theme, 'Nature-based Island Ecological Restoration and Management Practice.' The conference, which was held online and face-to-face, brought together front-line staff from government agencies, academic institutions and experts from major countries around the world to discuss emerging issues of sustainable island development.

Phase II trial of proton therapy versus photon IMRT for GBM: secondary analysis comparison of progression-free survival between RANO versus clinical assessment.

BACKGROUND: This secondary image analysis of a randomized trial of proton radiotherapy (PT) versus photon intensity-modulated radiotherapy (IMRT) compares tumor progression based on clinical radiological assessment versus Response Assessment in Neuro-Oncology (RANO). METHODS: Eligible patients were enrolled in the randomized trial and had MR imaging at baseline and follow-up beyond 12 weeks from completion of radiotherapy. "Clinical progression" was based on a clinical radiology report of progression and/or change in treatment for progression. RESULTS: Of 90 enrolled patients, 66 were evaluable. Median clinical progression-free survival (PFS) was 10.8 (range: 9.4-14.7) months; 10.8 months IMRT versus 11.2 months PT (P = .14). Median RANO-PFS was 8.2 (range: 6.9, 12): 8.9 months IMRT versus 6.6 months PT (P = .24). RANO-PFS was significantly shorter than clinical PFS overall (P = .001) and for both the IMRT (P = .01) and PT (P = .04) groups. There were 31 (46.3%) discrepant cases of which 17 had RANO progression more than a month prior to clinical progression, and 14 had progression by RANO but not clinical criteria. CONCLUSIONS: Based on this secondary analysis of a trial of PT versus IMRT for glioblastoma, while no difference in PFS was noted relative to treatment technique, RANO criteria identified progression more often and earlier than clinical assessment. This highlights the disconnect between measures of tumor response in clinical trials versus clinical practice. With growing efforts to utilize real-world data and personalized treatment with timely adaptation, there is a growing need to improve the consistency of determining tumor progression within clinical trials and clinical practice.
