目的 探讨采用多种方法手术结合X -刀治疗颅内肿瘤的疗效。方法 对 70例颅内肿瘤患者在X-刀治疗前采用多种方法手术处理。包括手术切除、立体定向抽吸囊液及立体定向活检 ,然后再行X -刀治疗。结果 手术切除和抽吸囊液使肿瘤体积明显缩小 ,立体定向活检明确了肿瘤的病理类型。依据X -刀治疗后患者临床症状和CT、MRI扫描肿瘤的大小变化观察 ,以临床症状大部分消失和病变显著缩小为显效 ,加重及增大为无效 ,介于两者之间为有效。 5 4例患者获得临床随访 ,时间为 3- 5 0个月。其中显效 4 4例 ;有效 9例 ;无效 1例。结论 对颅内肿瘤采用多种手术方法可缩小病变体积 ,明确肿瘤病理类型 ,并可为X -刀治疗计划的制定提供依据 ,提高疗效
Objective To investigate the curative effect of intracranial tumors treated by X - knife in combination with various methods. Methods Seventy patients with intracranial tumors were treated with various methods before X-knife treatment. Including surgical resection, stereotactic aspiration sac fluid and stereotactic biopsy, and then X-knife treatment. Results Surgical resection and aspiration of cyst fluid significantly reduced the size of the tumor. Stereotactic biopsy confirmed the pathological type of the tumor. According to the clinical symptoms of patients after X - knife treatment and CT, MRI changes in the size of the tumor were observed, most of the clinical symptoms disappeared and the lesion was significantly reduced as markedly effective, increased and increased as invalid, between the two effective. Fifty-four patients were clinically followed up for 3-50 months. Among them, 44 cases were markedly effective, 9 cases effective and 1 case ineffective. Conclusions The multiple intracranial tumors can be used to reduce the size of the lesion and to clarify the tumor pathological types. It can also provide the basis for the development of X - knife treatment plan and improve the curative effect
