Outcome of TACE treatment in HIV infected patients with hepatocellular carcinoma.

ABSTRACT: The surgical treatment and transcatheter arterial chemoembolization (TACE) rate of human immunodeficiency virus (HIV)-infected hepatocellular carcinoma (HCC) patients is relatively low in West China. For various reasons, most patients do not receive timely surgical treatment. Upon transfer to an infectious disease centralized hospital, they were already classified in the Barcelona Clinic Liver Cancer (BCLC)-B stage. A total of 2249 BCLC-B HCC patients were analyzed. The eligible population was divided into three groups for analysis of survival and prognostic factors; These were 21 HIV infected (HIV+) HCC patients treated with TACE (TACE+), 1293 non-HIV-infected (HIV-) HCC patients treated with TACE, and 150 HIV- HCC patients who only receive medication (TACE-) as a second control group. After 1:2 matching, 1- and 2-year survival of HIV+?TACE+?and HIV- TACE+?groups was 64.3% and 76.5% (P?=?0.453) and 45.5% vs. 50.0% (P?=?0.790) respectively. We also compared one and two-year survival between HIV+?TACE+?and HIV- TACE-. One-year overall survival was 64.3% vs. 45.7% (P?=?0.097) and 2-year survival was 45.5% vs. 7.1% (P?=?0.004). Multivariate analysis showed that the most important prognostic factors for survival were serum alpha-fetoprotein (AFP) and Child-Pugh score and tumor size, while HIV status had no significant effect on prognosis statistically. CD4 levels below 200 may increase the risk of opportunistic infection after surgery, but after anti-infection and systematic supportive therapy, it has no effect on survival. HIV+?patients should have the same treatment opportunities as HIV- patients. If the patient's immune status permits, we suggest that early TACE treatment should be administered to BCLC-B HCC patients, regardless of HIV infection.

Project description:Background and Aims: To investigate the impact of MR bias field correction on response determination and survival prediction using volumetric tumor enhancement analysis in patients with infiltrative hepatocellular carcinoma, after transcatheter arterial chemoembolization (TACE). Methods: This study included 101 patients treated with conventional or drug-eluting beads TACE between the years of 2001 and 2013. Semi-automated 3D quantification software was used to segment and calculate the enhancing tumor volume (ETV) of the liver with and without bias-field correction on multi-phasic contrast-enhanced MRI before and 1-month after initial TACE. ETV (expressed as cm3) at baseline imaging and the relative change in ETV (as % change, ETV%) before and after TACE were used to predict response and survival, respectively. Statistical survival analyses included Kaplan-Meier curve generation and Cox proportional hazards modeling. Q statistics were calculated and used to identify the best cut-off value for ETV to separate responders and non-responders (ETV cm3). The difference in survival was evaluated between responders and non-responders using Kaplan-Meier and Cox models. Results: MR bias field correction correlated with improved response calculation from baseline MR as well as survival after TACE; using a 415 cm3 cut-off for ETV at baseline (hazard ratio: 2.00, 95% confidence interval: 1.23-3.26, p=0.01) resulted in significantly improved response prediction (median survival in patients with baseline ETV <415 cm3: 19.66 months vs. ≥415 cm3: 9.21 months, p<0.001, log-rank test). A ≥41% relative decrease in ETV (hazard ratio: 0.58, 95%confidence interval: 0.37-0.93, p=0.02) was significant in predicting survival (ETV ≥41%: 19.20 months vs. ETV <41%: 8.71 months, p=0.008, log-rank test). Without MR bias field correction, response from baseline ETV could be predicted but survival after TACE could not. Conclusions: MR bias field correction improves both response assessment and accuracy of survival prediction using whole liver tumor enhancement analysis from baseline MR after initial TACE in patients with infiltrative hepatocellular carcinoma.

Project description:Background & aimsTranscatheter arterial chemoembolisation (TACE) is recommended for patients with hepatocellular carcinoma devoid of macrovascular invasion or extrahepatic spread but not eligible for curative therapies. We compared the efficacy and safety of the combination of a single TACE and external conformal radiotherapy (CRT) vs. classical TACE.MethodsTACERTE was an open-labelled, randomised controlled trial with a 1:1 allocation rate to two or three TACE (arm A) or one TACE + CRT (arm B). Participants had a mean age of 70 years, and 86% were male. The aetiology was alcohol in 85%. The primary endpoint was liver progression-free survival (PFS) in the intention-to-treat population. The typical CRT schedule was 54 Gy in 18 sessions of 3 Gy.ResultsOf the 120 participants randomised, 64 were in arm A and 56 in arm B; 100 participants underwent the planned schedule and defined the 'per-protocol' group. In intention-to-treat participants, the liver PFS at 12 and 18 months were 59% and 19% in arm A and 61% and 36% in arm B (hazard ratio [HR] 0.69; 95% CI 0.40-1.18; p = 0.17), respectively. In the per-protocol population, treated liver PFS tended to be better in arm B (HR 0.61; 95% CI 0.34-1.06; p = 0.081) than in arm A. Liver-related grade III-IV adverse events were more frequent in arm B than in arm A. Median overall survival reached 30 months (95% CI 23-35) in arm A and 22 months (95% CI 15.7-26.2) in arm B.ConclusionsAlthough TACE + CRT tended to improve local control, this first Western randomised controlled trial showed that the combined strategy failed to increase PFS or overall survival and led more frequently to liver-related adverse effects.Impact and implicationsHepatocellular carcinoma is frequently treated by arterial embolisation of the tumour and more recently by external radiotherapy. We tried to determine whether combination of the two treatments (irradiation after embolisation) might produce interesting results. Our results in this prospective randomised study were not able to demonstrate a beneficial effect of combining embolisation and irradiation in these patients. On the contrary, we observed more adverse effects with the combined treatment.Clinical trials registrationNCT01300143.
