Abstract PurposeThe aim of this study was to clarify the usefulness of the Liver Imaging Reporting and Data System (LI-RADS) to predict the patients’ prognosis after transcatheter arterial chemoembolization (TACE) combined with radiofrequency ablation (TACE-RFA) for hepatocellular carcinoma (HCC) of Barcelona-Clinic Liver Cancer Stage (BCLC) 0 or A.Materials and MethodsWe retrospectively analyzed cases of HCC patients who underwent TACE-RFA (Jan 2005 to Dec 2015). Patients’ nodules were categorized based on their LI-RADS v2018 core. The LI-RADS category was assigned to each nodule using dynamic contrast-enhanced CT. LR-3, LR-4 and LR-5 nodules were extracted. We assessed the overall survival (OS) and recurrence-free survival (RFS) among BCLC 0 and BCLC A patients.ResultsOf the 64 nodules extracted, 22 were LR-3 or -4 (14.8±6.7 mm) and 42 were LR-5 (17.1±6.9 mm). Regarding OS, there was no significant difference between LR-3 or -4 and LR-5 (p=0.278). In terms of RFS, there was a significant difference between LR-3 or -4 and LR-5 (p=0.03). In particular, patients with BCLC A with LR-5 nodules showed significantly poorer RFS than those with LR-3 or -4 (p=0.016) nodules. ConclusionsFor patients with BCLC A, LR-3 or -4 are associated with a better prognosis than LR-5 nodules.

Arterial Chemoembolization

Purpose: Contrast-enhanced sonography increases negative enhancement in the Kupffer phase after transcatheter arterial chemoembolization (TACE) for hepatocellular carcinoma (HCC). We compared contrast-enhanced sonography with B-mode sonography for guidance of radiofrequency ablation (RFA) of HCC after TACE. Methods: After TACE was performed, 18 nodules in 12 patients were treated by B-mode sonography guided RFA, while 22 nodules in 18 patients were treated by contrast-enhanced sonography-guided RFA. Results: The success rate of initial RFA was 83.3% (15/18 nodules) in the B-mode sonography group. On the other hand, the success rate was 100% (22/22 nodules) in the contrast-enhanced sonography group and the difference was significant (p = 0.046). Conclusion: These findings suggest that RFA guided by Kupffer phase contrast-enhanced sonography after TACE is a promising therapeutic option for curing HCC.

Adrenal Masses

Abstract Background The term adrenal incidentaloma (AI), by definition, is an adrenal mass that is unexpectedly detected through an imaging procedure performed for reasons unrelated to adrenal dysfunction or suspected dysfunction. Despite their frequent appearance, the challenge remains in recognizing and treating the small percentage of AI that poses a significant risk, either because of their hormonal activity or because of their malignant histology. The aim of this study is to study the role of MRI, specifically chemical shift imaging (CSI), against various MDCT scans (non-enhanced, enhanced, and delayed) in the characterization of incidentally discovered adrenal masses to offer a way for the patients to avoid unnecessary time and money-wasting imaging modalities used to reach a diagnosis of their incidentally discovered adrenal lesions. We examined a total number of 20 patients with total of 22 adrenal lesions. The mean age was 51.1 ± 15.27. Results In our study, we found that among CT parameters, APW and RPW showed the highest sensitivity and specificity for detection of lipid-rich adenomas. CSI has also proven to be the best MR technique. However, there is no statistically significant difference in the diagnostic capability of CSI versus the CT washout technique. Both modalities could be conducted, according to specific patient preferences and/or limitations, with comparable highly accurate outcomes. Conclusion This study demonstrates that a similar diagnostic outcome is obtained from contrast-enhanced CT (CECT) and MRI with CSI of adrenal lesions.

Arterial Chemoembolization

Abstract Background There is still some debate as to whether transcatheter arterial chemoembolization (TACE) plus radiofrequency ablation (RFA) is better than TACE or RFA alone. This meta-analysis aimed to compare the efficacy and safety of TACE plus RFA for hepatocellular carcinoma (HCC) with RFA or TACE alone. Methods We searched PubMed, MEDLINE, Embase, Cochrane Library, and CNKI (China National Knowledge Infrastructure) for all relevant randomized controlled trials and retrospective studies reporting overall survival (OS), recurrence-free survival (RFS), and complications of TACE plus RFA for HCC, compared with RFA or TACE alone. Results Twenty-one studies involving 3413 patients were included. TACE combined with RFA was associated with better OS (hazard ratio [HR]=0.62, 95% confidence intervals [CI] = 0.55–0.71, P < 0.001) and RFS (HR = 0.52, 95% CI = 0.39–0.69, P < 0.001) than TACE alone; compared with RFA alone, TACE plus RFA resulted in longer OS (HR = 0.63, 95% CI = 0.53–0.75, P < 0.001) and RFS (HR = 0.60, 95% CI = 0.51–0.71, P < 0.001). Subgroup analyses by tumor size also showed that combined treatment resulted in better OS and RFS compared with RFA alone in patients with HCC larger than 3 cm. Combined treatment resulted in similar rate of major complications compared with TACE or RFA alone (OR = 1.78, 95% CI = 0.99–3.20, P = 0.05; OR = 1.00, 95% CI = 0.42–2.38, P = 1.00, respectively). Conclusions TACE combined with RFA was more effective for HCC than TACE alone. For patients with a tumor larger than 3 cm, the combined treatment also achieved a better effect than RFA alone.

Arterial Chemoembolization

Purpose To compare radiofrequency ablation (RFA) with or without transcatheter arterial chemoembolization (TACE) in the treatment of hepatocellular carcinoma (HCC). Patients and Methods A randomized controlled trial was conducted on 189 patients with HCC less than 7 cm at a single tertiary referral center between October 2006 and June 2009. Patients were randomly asssigned to receive TACE combined with RFA (TACE-RFA; n = 94) or RFA alone (n = 95). The primary end point was overall survival. The secondary end point was recurrence-free survival, and the tertiary end point was adverse effects. Results At a follow-up of 7 to 62 months, 34 patients in the TACE-RFA group and 48 patients in the RFA group had died. Thirty-three patients and 52 patients had developed recurrence in the TACE-RFA group and RFA group, respectively. The 1-, 3-, and 4-year overall survivals for the TACE-RFA group and the RFA group were 92.6%, 66.6%, and 61.8% and 85.3%, 59%, and 45.0%, respectively. The corresponding recurrence-free survivals were 79.4%, 60.6%, and 54.8% and 66.7%, 44.2%, and 38.9%, respectively. Patients in the TACE-RFA group had better overall survival and recurrence-free survival than patients in the RFA group (hazard ratio, 0.525; 95% CI, 0.335 to 0.822; P = .002; hazard ratio, 0.575; 95% CI, 0.374 to 0.897; P = .009, respectively). There were no treatment-related deaths. On logistic regression analyses, treatment allocation, tumor size, and tumor number were significant prognostic factors for overall survival, whereas treatment allocation and tumor number were significant prognostic factors for recurrence-free survival. Conclusion TACE-RFA was superior to RFA alone in improving survival for patients with HCC less than 7 cm.
