研究目的:

癌症是世界范围内人口死亡的主要原因,放射治疗是治疗肿瘤的主要途径之一,绝大多数腹盆腔癌症患者都需要在治疗过程中接受放疗。然而放疗可以杀伤肿瘤细胞外的正常细胞,其辐射毒性难以忽视。胃肠道是更新最快的成人组织,正常的小肠上皮细胞对辐射高度敏感,是腹盆腔放疗时损伤的主要部位,其常见病变包括放射性肠炎(RE)等。 肠道细菌组成的肠道菌群主要功能是帮助宿主从食物中获取营养和能量。此外,肠道菌群也通过刺激宿主的免疫系统发育、防止病原体入侵宿主及调节大脑发育和行为来影响宿主代谢及生理过程。平衡互利的菌群-宿主相互作用不仅在肠道局部炎症的发生机制中起关键作用,还在调节全身代谢、肠外炎症及中枢神经系统的功能中也起到关键作用。已有研究表明RE患者的肠道菌群以与正常人群间存在差异,肠道菌群参与影响辐射损伤的结局。但肠道菌群在RE中发挥作用的具体机制尚未被阐明。 本研究旨在探究肠道菌群与腹盆腔放疗的关系。  

Objectives of Study:

Cancer is the leading cause of mortality worldwide. Radiotherapy represents a primary modality for tumor treatment, with the majority of patients suffering from abdominal and pelvic cancer requiring radiotherapy as part of their therapeutic regimen. However, it should be noted that radiotherapy can induce damage to normal cells surrounding tumors, thereby presenting challenges in terms of radiation toxicity management. The gastrointestinal tract, known for its rapid cell turnover in adults, particularly exhibits high sensitivity to radiation and serves as a major site of injury during abdominal and pelvic radiotherapy. Intestinal bacteria primarily constitute the gut microbiota and play a crucial role in facilitating nutrient absorption and energy acquisition for the host organism. Moreover, they exert influence on host metabolism and physiological processes by promoting immune system development, preventing pathogenic invasion, regulating brain function and behavior.Maintaining a balanced interaction between mutually beneficial microbiota-host relationships not only plays a pivotal role in local intestinal inflammation pathogenesis but also significantly impacts systemic metabolism regulation, extraintestinal inflammation modulation as well as central nervous system functionality.Previous studies have demonstrated differences in gut microbiota composition between individuals experiencing RE compared to healthy subjects; implicating an involvement of gut microbiota in RE outcomes. Nevertheless,the precise mechanisms underlying how gut microbiota influences RE remain elusive. The objective of this study is to investigate the correlation between gut microbiota and abdominal and pelvic radiotherapy.
