目的:报道应用新的B超检查参数(最大交叉截面积)测量评估随访患者的脉络膜转移肿瘤的大小。方法:报告1例脉络膜转移癌患者,在随访中应用B超测量其肿瘤的高、基底和最大交叉截面积。结果:一位62岁华人老年妇女,已知为肺非小细胞癌患者,表现为右眼无痛性视物模糊。被诊为双眼脉络膜转移癌(右眼进展期,左眼初期),双眼视力良好。首次化疗后右眼肿瘤明显减小,但最后一轮化疗结束后6wk即出现增长。患者又进行了放疗和另一轮的化疗后右眼肿瘤大小没有变化。左眼肿瘤大小在随后的2a内没有变化。双眼维持着最佳矫正视力(右6/9,左6/6)。对右眼肿瘤的大小进行了连续B超测量评估。结论:超声检测在随访中是可重复的,并与右眼肿瘤临床表现相符。我们建议在治疗阶段应用B超对脉络膜肿瘤的大小进展或转归进行定量评估。
PURPOSE: To report the size of choroidal metastatic tumors in follow-up patients assessed using new B-ultrasound parameters (maximal cross-sectional area) measurements. Methods: One case of choroidal metastatic carcinoma was reported. The height, basal and maximal cross-sectional area of tumor were measured by B-ultrasound at follow-up. Results: A 62-year-old Chinese elderly woman, known as a non-small cell lung cancer patient, showed a pain-free blurred vision of the right eye. He was diagnosed with bilateral choroidal metastases (right eye progress, early left eye), and binocular vision was good. Right eye after the first chemotherapy significantly reduced the tumor, but the final round of chemotherapy after 6wk that increase. There was no change in the size of the right eye tumor after the patient underwent radiotherapy and another round of chemotherapy. The size of the left eye tumor did not change in the following 2a. Eyes maintained the best corrected visual acuity (right 6/9, left 6/6). The size of the right eye tumor was evaluated by continuous B-mode ultrasound. CONCLUSIONS: Ultrasonography is repeatable at follow-up and is consistent with the clinical presentation of right-sided tumors. We suggest using B ultrasound to assess quantitatively the progression or outcome of choroidal tumors in the treatment phase.
