Objective: This study aims to evaluate the impact and potential prognostic roles of the pre- and post-treatment Glasgow prognostic score (GPS) and the change thereof in patients with advanced head and neck cancer undergoing concurrent chemoradiotherapy (CCRT). Methods: We collected GPS and clinicopathological data of 139 stage III, IVA, and IVB head and neck cancer patients who underwent CCRT between 2008 and 2011. Their GPSs pre- and post-CCRT and the change thereof were analyzed for correlations with recurrence and survival. Results: The GPS changed in 72 (51.8%) patients, with worse scores observed post-CCRT in 65 (90.3%) of the GPS changed patients. Patients in the improved GPS group showed a tendency toward better survival. From the multivariate analysis, the post-CCRT GPS level was an independent prognostic factor in addition to tumor stage. Conclusions: After CCRT, a high GPS was revealed to be an important predictor of survival for advanced head and neck cancer.

Volatile organic compounds (VOC) have been proven to cause considerable harm to both the ecological environment and human health. Anthropogenic VOC emissions are primarily generated by the industrial sector. The utilization of porous carbon as an adsorbent has emerged as an effective method for the efficient removal of VOC from industrial sources. However, during the actual production processes, VOC exhaust gases are often mixed with water vapor, which poses challenges for adsorption purification. This review provides a comprehensive overview of the remarkable advancements in various carbon materials in terms of their ability to adsorb both VOC and water vapor. Additionally, it systematically summarizes the influence of surface groups on adsorbents and the molecular properties of VOC on their adsorption by carbon materials. Furthermore, this review introduces the mechanism underlying adsorption-adsorbent interactions and discusses the construction of models for adsorbing water vapor and VOC. The challenges associated with the application of carbon materials for VOC adsorption in humid environments are also addressed. This review aims to offer theoretical and technical guidance for the effective purification of moist VOC waste gases emitted from industrial sources, thereby achieving precise control of VOC emissions.
