摘要

目的:回顾性确定冷冻消融前经皮肾穿刺活检对小肾癌的诊断准确性。方法:在这项研究中,216名患者在九州大学医院冷冻消融前接受了242个肾脏病变的经皮核心活检,这些病变在图像上被怀疑是肾细胞癌。我们计算了组织学诊断的成功率,并调查了可能导致诊断成功的因素。还评估了活检过程引起的并发症。结果:203个病灶的组织学诊断成功(82.8%),直径≤15mm的肿瘤组织学诊断的成功率为65.4%(34/52例),直径>15mm的肿瘤的组织学确诊成功率为88.9%(169/190例),在单变量和多变量分析中,肿瘤直径是影响组织学诊断成功率的一个因素(P<0.001)。对于肿瘤直径≤15mm的病变,在碘油前标记的情况下,组织学诊断的成功率从50.0%增加到76.2%,在活检程序与冷冻消融分开进行时,组织学确诊的成功率增加到85.7%;后者具有统计学意义(P=0.039)。活检术可能引起的主要并发症为3级出血和行道播种术(各1例)。对于肿瘤直径≤15 mm的病变,单独的活检程序和碘油前标记可以提高诊断准确性。

Diagnostic accuracy of percutaneous core biopsy before cryoablation for small-sized renal cell carcinoma.

Purpose: To retrospectively determine the diagnostic accuracy of a percutaneous core biopsy performed before cryoablation for small-sized renal cell carcinoma.

Methods: In this study, 216 patients underwent a percutaneous core biopsy for 242 renal lesions suspected to be renal cell carcinoma on image findings before cryoablation at Kyushu University Hospital. We calculated the success rate of the histological diagnosis and investigated factors that may have contributed to the diagnostic success. Complications caused by the biopsy procedure were also evaluated.

Results: The histological diagnosis was successful in 203 lesions (82.8%). The success rate of the histological diagnosis was 65.4% (34/52 cases) for tumors with a diameter of ≤15 mm and 88.9% (169/190 cases) for those >15 mm. Therefore, tumor diameter was a factor contributing to the histological diagnosis success rate in both univariate and multivariable analyses (P < 0.001). For lesions with a tumor diameter ≤15 mm, the histological diagnosis success rates increased from 50.0% to 76.2% in the presence of pre-lipiodol marking and to 85.7% when the biopsy procedure was performed separately from cryoablation; the latter was statistically significant (P = 0.039). Major complications that may have been caused by the biopsy procedure were grade 3 bleeding and tract seeding (one case each).

Conclusion: Percutaneous core biopsy in cryoablation for small-sized renal cell carcinoma had a high diagnostic rate and was safely performed. For lesions with a tumor diameter ≤15 mm, a separate biopsy procedure and pre-lipiodol marking may improve the diagnostic accuracy.
