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
(n=31)
Irradiated HCCs targeted during TACE or TAI
(n=18)
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.
