胃肠道肺转移瘤患者20例(56个病灶),其中单肺13例、双肺7例。利用计算机三维立体定向治疗计划系统计算布源,在CT引导下将125I粒子植入肺转移瘤灶内。观察2个月,56个病灶中CR32个,PR19个,NC5个,总有效率91.1%,2个月内无死亡病例,并发气胸2例、咯血痰2例、胸腔出血1例(均经常规治疗后好转)。认为胃肠道肺转移瘤肺内病灶5个以下、最大直径不超过3cm者,采用CT导向125I粒子植入治疗,创伤小,并发症少,近期疗效好。
Twenty patients with gastrointestinal metastases (56 lesions), including 13 cases of single lung and 7 cases of double lung. Three-dimensional computerized stereotactic treatment planning system to calculate the cloth source, under the guidance of CT 125I particles implanted lung metastases within the tumor. Observation 2 months, 56 lesions in CR32, PR19, NC5, the total effective rate 91.1%, no deaths within 2 months, 2 cases of complicated pneumothorax, hemoptysis sputum in 2 cases, 1 case of thoracic bleeding (both conventional After treatment improved). Considered less than 5 lesions in the lungs of the gastrointestinal tract lung metastases, the maximum diameter of not more than 3cm, the use of CT-guided 125I seed implantation, less trauma, fewer complications, the recent good effect.
