Abstract

The objective of this study was to evaluate unidimensional (mm), bidimensional (mm2), or tridimensional (mL) computed tomography (CT) tumor measurements for ability to discriminate changes in lesion size and predict survival in dogs with nonresectable hepatic carcinoma treated with drug-eluting bead transarterial-chemoembolization (DEB-TACE) and to compare CT response via Response Evaluation Criteria in Solid Tumors 1.1 (mm), World Health Organization (mm2), ellipsoid and spherical volume (mL), and percent necrosis, for their ability to differentiate treatment responders. This was a prospective, single-arm clinical trial. DEB-TACE was performed to varying levels of blood flow stasis in 16 client-owned dogs with nonresectable hepatic carcinoma. Computed tomography imaging responses were assessed and compared to median survival time. Results revealed that initial, follow-up, or changes in unidimensional, bidimensional, or tridimensional tumor measurements were not associated with survival. Larger bidimensional and tridimensional tumor measurements/body weight on initial and follow-up CT were significantly associated with a shorter median survival time [bidimensional (P = 0.04, 0.016) and tridimensional (P = 0.025, 0.015), respectively]. A higher percent necrosis on initial CT was significantly associated with a shorter median survival time (P = 0.038). Ellipsoid volumetric criteria detected treatment response most frequently; however, response classification was not associated with median survival time. Computed tomography bidimensional and tridimensional tumor measurements/body weight before and after DEB-TACE may help to predict median survival time for dogs undergoing DEB-TACE for hepatic carcinoma.

犬肝癌化疗栓塞后ct反应标准的比较。
本研究的目的是评估单维(mm)、二维(mm2)或三维(mL)计算机断层扫描(CT)肿瘤测量在鉴别病变大小变化和预测不可切除肝癌犬的生存能力方面的作用,并通过实体瘤1.1 (mm)、世界卫生组织(mm2)、椭球和球形体积(mL)的反应评价标准比较CT反应。以及坏死百分率,因为它们区分治疗反应者的能力。这是一项前瞻性单臂临床试验。对16只患有不可切除肝癌的狗进行了不同程度的血流量停滞的DEB-TACE治疗。评估计算机断层成像反应并比较中位生存时间。结果显示,初始、随访或单维、二维或三维肿瘤测量的变化与生存无关。初始和随访CT上较大的二维和三维肿瘤尺寸/体重与较短的中位生存时间显著相关[二维(P = 0.04, 0.016)和三维(P = 0.025, 0.015)]。初始CT坏死率越高,中位生存时间越短(P = 0.038)。椭球体积标准最常检测到治疗反应;然而,反应分类与中位生存时间无关。DEB-TACE前后的计算机断层扫描二维和三维肿瘤测量/体重可能有助于预测肝癌犬接受DEB-TACE的中位生存时间。
