The effectiveness of transarterial chemoembolization in recurrent hepatocellular-cholangiocarcinoma after resection.

ABSTRACT: BACKGROUND:Combined hepatocellular-cholangiocarcinoma (cHCC-CC) can present as a hypervascular or peripherally enhancing tumor in dynamic imaging. We evaluated the effect of transarterial chemoembolization (TACE) on prognosis according to post-operative recurrence imaging patterns. METHODS:We retrospectively analyzed 42 cHCC-CC and 59 hepatocellular carcinoma (HCC-control) patients at the Asan Medical Center. We classified recurrent cHCC-CC according to enhancement pattern (globally enhancing: GE cHCC-CC, peripherally enhancing: PE cHCC-CC) and evaluated tumor response, time-to-local progression (TTPlocal), and overall survival (OS). RESULTS:The GE cHCC-CC group had a significantly higher best objective response rate (complete remission + partial response) than the PE cHCC-CC group (36% vs 0%, P = 0.005), and it was comparable to that of the HCC-control group (35.6%, P = 0.97). TTPlocal in the GE cHCC-CC group was significantly shorter than in the HCC-control group (6.6 vs 27.1 months, P < 0.001), and was not significantly different from that in the PE cHCC-CC group (5.3 months, P = 0.12). OS was 12.4 months, 52.8 months, and 67.5 months in the PE cHCC-CC, GE cHCC-CC, and HCC-control groups, respectively (Ps < 0.05). The adjusted hazard ratios (HRs) for TTPlocal and OS revealed an independent association with enhancement pattern of recurrent cHCC-CC (TTPlocal: HR 2.46; 95% CI 1.10-5.46; P = 0.03; OS: HR 5.97; 95% CI 2.38-14.96; P < 0.001). CONCLUSIONS:The GE cHCC-CC group showed better response and prognosis after TACE than the PE cHCC-CC group, but poorer response and prognosis than the HCC-control group. Enhancement patterns at recurrence were crucially associated with tumor response and overall survival.

Project description:BackgroundThe effectiveness of adjuvant transarterial chemoembolization (TACE) for intrahepatic cholangiocarcinoma (ICC) after hepatectomy remains unclear. This study was performed to identify ICC patients who would benefit from adjuvant TACE.Patients and methodsThe study included 553 patients who underwent hepatectomy for ICC between January 2008 and February 2011 at the Eastern Hepatobiliary Surgery Hospital and who were treated with or without TACE (122 with TACE and 431 without TACE). Survival risk stratification was performed using the established prognostic nomogram (ICC nomogram). The predictive performance was evaluated by concordance index and calibration. The tumor recurrence and overall survival (OS) rates were analyzed by the Kaplan-Meier method before and after propensity score matching (PSM).ResultsThe predictive performance of the ICC nomogram was demonstrated by the well-fitted calibration curves and an optimal c-index of 0.71 for OS prediction. In the whole cohort, the 5-year recurrence and OS rates between the TACE and non-TACE groups were significantly different (5-year recurrence: 72.9% vs. 78.1%; OS: 38.4% vs. 29.7%). After 1:1 PSM, the TACE and non-TACE groups (122 patients each) had similar 5-year recurrence and OS rates (5-year recurrence: 72.9% vs. 74.2%; OS: 38.4% vs. 36.0%). By survival risk stratification based on ICC nomogram, only the patients in the lowest tertile (nomogram scores ?77) benefited from adjuvant TACE (TACE vs. non-TACE groups: 90.4% vs. 95.9% for 5-year recurrence; 21.3% vs. 6.2% for 5-year OS).ConclusionAdjuvant TACE following liver resection might be suitable for ICC patients with high ICC nomogram scores (?77).Implications for practiceThe accurate predictive performance of the established prognostic nomogram for intrahepatic cholangiocarcinoma (ICC) following liver resection was reconfirmed in an independent cohort with 553 patients. Based on the survival risk stratification using the nomogram, adjuvant transarterial chemoembolization following liver resection might be suitable only for ICC patients with high scores from the nomogram.

Project description:BackgroundOptimal administration of transarterial chemoembolization (TACE), the standard approach for intermediate-stage hepatocellular carcinoma (HCC), requires clinical and technical expertise. We sought to evaluate whether TACE retains its effectiveness when administered across a broad range of health care settings. Furthermore, as the use of yttrium(90) (Y(90)) radioembolization has been increasing, we explored the comparative effectiveness of Y(90) as an alternative to TACE.MethodsPatients with HCC diagnosed from 2004 through 2009 treated initially with TACE or Y(90) were identified from the SEER-Medicare linkage. Key covariates included prediagnosis α-fetoprotein (AFP) screening, complications of cirrhosis, and tumor extent. Effect of treatment, patient, and health care system factors on overall survival (OS) was evaluated using multivariable Cox proportional hazards. Stratified OS estimates are provided. Propensity score (PS) weighting was used to compare effectiveness of Y(90) with TACE.ResultsOf 1528 patients who underwent intra-arterial embolization, 577 received concurrent chemotherapy (eg, TACE). Median OS was 21 months (95% CI, 18-23) following TACE and 9 months (95% CI, 1-41) following Y(90). Refined survival estimates stratified by stage, AFP screening, and liver comorbidity are presented. The 90-day mortality rate after TACE was 21% to 25% in patients with extrahepatic spread or vascular invasion. In the PS-weighted analysis, Y(90) was associated with inferior survival, with an adjusted hazard ratio of 1.39 (95% CI, 1.02-1.90).ConclusionsThe effectiveness of TACE is generalizable to Medicare patients receiving care in a variety of treatment settings. However, early posttreatment mortality is high in patients with advanced disease. We found no evidence of improved outcomes with Y(90) compared with TACE. Survival estimates from this large cohort can be used to provide prognostic information to patients considering palliative TACE.
