氧效应在肿瘤的放射治疗中起着重要的作用 ,贫血将影响到肿瘤的氧合状态 ,从而影响到肿瘤的放射敏感性。然而 ,贫血是否影响到正常组织的氧合状态及血红蛋白 (Ｈｂ)和正常组织放射损伤的关系报道尚少。笔者就鼻咽癌患者Ｈｂ和早期黏膜放射反应的关系进行回顾性分析。一、材料与 Oxygen effect plays an important role in the radiation therapy of tumors, and anemia will affect the oxygenation status of the tumor, thus affecting the radiosensitivity of the tumor. However, whether anemia affects the oxygenation status of normal tissues and the relationship between hemoglobin (Hb) and normal tissue is still low. The author of nasopharyngeal carcinoma Hb and early mucosal radiation response to a retrospective analysis. First, the material and
