BACKGROUND AND AIMS:

Conventional transarterial chemoembolization (cTACE) is used to treat patients with hepatocellular carcinoma (HCC). Radioembolization is a minimally invasive procedure that involves implantation of radioactive micron-sized particles loaded with yttrium-90 (Y90) inside the blood vessels that supply a tumor. We performed a randomized, phase 2 study to compare the effects of cTACE and Y90 radioembolization in patients with HCC.

METHODS:

From October 2009 through October 2015, we reviewed patients with HCC of all Barcelona Clinic Liver Cancer (BCLC) stages for eligibility. Of these, 179 patients with BCLC stages A or B met our enrollment criteria and were candidates for cTACE or Y90 therapy. Patients were randomly assigned to groups that received Y90 therapy (n=24, 50% Child-Pugh A) or cTACE (n=21, 71% Child-Pugh A). The primary outcome was time to progression (TTP), evaluated by intention to treat analysis. Secondary outcomes included safety, rate of response (based on tumor size and necrosis criteria), and KM survival time. We performed inverse probability of censoring weighting and competing risk analyses.

RESULTS:

Patients in the Y90 radioembolization group had significant longer median TTP (>26 months) than patients in the cTACE group (6.8 months) (P=.0012) (hazard ratio=0.122; 95% CI, 0.027-0.557; P=.007). This was confirmed by competing risk and inverse probability of censoring weighting analyses accounting for transplantation or death. A significantly greater proportion of patients in the cTACE group developed diarrhea (21%) than in the Y90 group (0%; P=.031) or hypoalbuminemia (58% in the cTACE group vs 4% in the Y90 group) (P<.001). Similar proportions of patients in each group had a response to therapy, marked by necrosis (74% in the cTACE group vs 87% in the Y90 group) (P=.433). Median survival time, censored to liver transplantation, was 17.7 months for the cTACE group (95% CI, 8.3-NC) vs 18.6 months for the Y90 group (95% CI, 7.4-32.5) (P=.99).

CONCLUSIONS:

In a phase 2 study of patients with HCC of BCLC stages A or B, we found Y90 radioembolization to provide significantly longer TTP than cTACE. Y90 radioembolization provides better tumor control and could reduce dropout from transplant waitlists. ClinicalTrials.gov no. NCT00956930.

 
Question posée
 
Comparaison de la chimioembolisation à la radioembolisation, étude randomisée phase 2.
 
Question posée
 
Meilleurs temps jusqu’à progression pour les patients traités par radioembolisation, pas de différence de survie (mais effectif limité). Plus de diarrhée et d’hypoalbuminémie dans le groupe chimioembolisation et une tendance à plus de fatigue chez les patients traités par radioembolisation (p = 0.08). Les patients traités par radioembolisation le sont en ambulatoire ! En conclusion petit bénéfice pour la radioembolisation.
