Methods: A total of 92 eases of advanced primary liver cancer underwent TACE and RFA treatment from June 2005 to 2011 at the Department of Hepatobiliary Surgery, the First Affiliated Hospital of Bengbu Medical College. A total of 88 cases with complete clinical treatment and follow-up data were divided into two groups: 43 patients treated with TACE (TACE group) and 45 patients that received TACE combined with RFA treatment (TACE + RFA group). After clinical data assessment, tumor size and survival status were not significantly different between the groups as determined by stratified analysis. Results: Before and after surgery, spiral CT radiography and color comparison observed ablation conditions. The tumor necrosis rates after treatment (CR + PR) were 67.4% (29/43) and 91.1% (41/45) for the TACE and combined treatment groups, respectively, and the difference was statistically significant (P〈0.05). The quality of life was significantly improved for patients undergoing TACE ~ RFA compared with the control group. Survival duration was not significantly different in patients undergoing TACE ~ RFA compared with the control group. Conclusions: In this study, the effect of RFA combined with TACE treatment was better than TACE alone in treating advanced HCC.展开更多

Methods: One hundred and thirty-five patients with clinically and pathologically diagnosed MLC (from gastrointestinal tumors) were included in the present study, and 104 of them had received CEUS prior to RFA to assess the number, size, shape, infiltration, location and enhancing features of the lesions. Among the 204 patients, 21 (20.1%) were excluded from RFA treatment due to too many lesions or large infiltrative range based on CEUS. The remaining 83 patients with 147 lesions underwent RFA (group A). During the same period, other 32 patients with 202 lesions serving as control group were treated based on findings of conventional ultrasound without contrast (group B). The patients underwent follow-up enhanced CT at the 1st month, and then every 3-6 months after RFA. The tumor was considered as early necrosis if no contrast enhancement was detected in the treated area on the CT scan at the 2st month. Results: In group A, 72 of 147 MLC lesions (48.9%) showed increased sizes on CEUS. Among them, 48 lesions (66.6%) appeared enlarged in arterial phase, and 24 (33.3%) showed enlarged hypoechoic area in parenchymal phase. CEUS showed total 61 additional lesions in 35 patients (42.2%) (ranged from 8 to 15 mm) compared with conventional ultrasound (US), and 42 (68.8%) of them were visualized in parenchymal phase only. There were total 208 lesions in group A underwent RFA with CEUS planning, and the tumor necrosis rate was 94.2% (196/208). In this group, local recurrence was found in 26 lesions (7.7%) during 3-42 months' following up, and new metastases were seen in 30 cases (36.2%). For group B, the tumor necrosis rate was 86.3% (88/202), local recurrence in 27 lesions (16.7%), and new metastases in 13 cases (41.9%). Tumor early necrosis and recurrence rates展开更多
