PURPOSE
To evaluate published methods of estimating choroidal melanoma volume.
DESIGN
Prospective consecutive case series.
PARTICIPANTS
Ten consecutive patients with primary choroidal melanoma.
METHODS
After determination of tumor dimensions (largest tumor basal diameter, basal perpendicular diameter, and height), tumor volume was calculated for each tumor by using the 5 published methods. Percent differences in tumor volume were determined for each tumor as calculated by different methods.
MAIN OUTCOME MEASURE
Choroidal melanoma volume.
RESULTS
The mean variation in estimated tumor volume expressed as a ratio was 2.33 (range, 1.64-3.84).
CONCLUSIONS
Choroidal melanoma volume calculation methods are inconsistent and caution is needed when volume measures are used for prognostic classification.
目的
评估已发表的脉络膜黑色素瘤体积估计方法。
设计
前瞻性连续病例系列。
参与者
连续10例原发性脉络膜黑色素瘤患者。
方法
在确定肿瘤尺寸（最大肿瘤基底直径、基底垂直直径和高度）后，使用5种已发表的方法计算每个肿瘤的体积。确定每种方法计算的每个肿瘤的体积百分比差异。
主要观察指标
脉络膜黑色素瘤体积。
结果
以比率表示的估计肿瘤体积的平均变化为2.33（范围为1.64 - 3.84）。
结论
脉络膜黑色素瘤体积计算方法不一致，当使用体积测量进行预后分类时需要谨慎。
