Angiographic Findings in Patients with Hepatocellular Carcinoma Previously Treated Using Proton Beam Therapy

Table 2

The prevalence of PBT-related angiographic findings at the initial hepatic angiography according to HCC targeting.

Angiographic findings Total
Irradiated HCCs targeted during TACE or TAI
Irradiated HCCs NOT targeted during TACE or TAI (n=13)

Abnormal staining of irradiated liver parenchyma22 (71%)14 (78%)8 (62%)0.326
Development of tortuous tumor feeder13 (42%)13 (72%)0 (0%)<0.001
Development of extrahepatic collateral pathway7 (23%)5 (28%)2 (15%)0.415
Development of AP/AV shunt4 (13%)4 (22%)0 (0%)0.069

The chi-squared test was used to calculate p-values. Irradiated HCCs refer to the TACE/TAI-targeted tumors being within the PBT irradiation field.
TACE: transarterial chemoembolization, TAI: transcatheter arterial infusion, PBT: proton beam therapy, HCC: hepatocellular carcinoma, AP/AV: arterio-portal or arteriovenous.
