To assess the objective and subjective image quality, and respiratory motion of hepatocellular carcinoma with portal vein tumor thrombosis (PVTT) using the contrast-enhanced four-dimensional dual-energy computed tomography (CE-4D-DECT). For twelve patients, the virtual monochromatic image (VMI) derived from the CE-4D-DECT with the highest contrast to noise ratio (CNR) was determined as the optimal VMI (O-VMI). To assess the objective and subjective image quality, the CNR and five-point score of the O-VMI were compared to those of the standard VMI at 77 keV (S-VMI). The respiratory motion of the PVTT and diaphragm was measured based on the exhale and inhale phase images. The VMI at 60 keV yielded the highest CNR (4.8 ± 1.4) which was significantly higher (p = 0.02) than that in the S-VMI (3.8 ± 1.2). The overall image quality (4.0 ± 0.6 vs 3.1 ± 0.5) and tumor conspicuity (3.8 ± 0.8 vs 2.8 ± 0.6) of the O-VMI determined by three radiation oncologists was significantly higher (p < 0.01) than that of the S-VMI. The diaphragm motion in the L-R (3.3 ± 2.5 vs 1.2 ± 1.1 mm), A-P (6.7 ± 4.0 vs 1.6 ± 1.3mm) and 3D (8.8 ± 3.5 vs 13.1 ± 4.9 mm) directions were significantly larger (p < 0.05) compared to the tumor motion. The improvement of objective and subjective image quality was achieved in the O-VMI. Because the respiratory motion of the diaphragm was larger than that of the PVTT, we need to be pay attention for localizing target in radiotherapy.

The purpose of the study was to analyze the clinical effect of stereotactic radiosurgery (SRS) (Cyberknife) on hepatocellular carcinoma with portal vein tumor thrombosis (HCC-PVTT). Data from 50 patients with HCC-PVTT who received Cyberknife from August 2013 to April 2016 was collected for efficacy analysis. Moreover, survival correlation was evaluated by Cox proportionalhazards model. The total effective rate in 1–3 months after treatment was 64.00%, including 7 cases in complete remission, 12 cases in partial remission, 13 cases in stable conditions, and 18 cases with enlargement; a 4–24-months follow-up (with an average of 11.58 ± 2.58 months) showed that median survival, 1-year cumulative survival rate, and 2-year cumulative survival rate were, respectively, 11.86 ± 1.79 months, 48.00%, and 20.00%. Moreover, the Cox proportional-hazards model indicates that it was with no correlation between lesion diameter, classification of liver function, pre-operative alphafetoprotein, types of hepatitis, number of tumors, ascites, types of tumor emboli, total dose, and survival rate. SRS is effective for HCC-PVTT and serves as an ideal treatment clinically to help preserve patients’ lives, which is worthy of clinical promotion and application.
