有一种罕见的恶性眼瘤,用典型的方法治疗要把整个眼睛摘除,而LBL 和UCSF 的医生们用放射治疗保全了患者的眼睛,其成功率达90%。医生们用LBL 的184英寸回旋加速器的氧离子束照射肿瘤,在过去5年内治疗患有脉络膜黑瘤的110多个患者的肿瘤,几乎全部巳经能够稳定住或者使肿瘤缩小。有三分之二以上的患者能够保住正常的视力或者视力至少可矫正到20/100。经治疗的患者没有一个产生新的转移,即从原来的肿瘤扩散成新
There is a rare malignant eye tumor that is treated with typical methods to remove the entire eye. The LBL and UCSF doctors used radiotherapy to protect the patient’s eyes with a success rate of 90%. The doctors used an oxygen ion beam from the LBL’s 184-inch cyclotron to irradiate the tumor. In the past five years, tumors in more than 110 patients with choroidal melanoma have been treated. Almost all culprit can stabilize or shrink tumors. More than two-thirds of patients can maintain normal vision or vision can be corrected to at least 20/100. None of the treated patients developed new metastases, ie they spread from the original tumor into new ones.
