Transarterial infusion chemotherapy with epirubicin in water-in-oil-in-water emulsion for recurrent hepatocellular carcinoma in the residual liver after hepatectomy

Purpose

To evaluate the midterm results of transarterial infusion (TAI) with water-in-oil-in-water (W/O/W) emulsion containing an anticancer agent for patients with recurrent hepatocellular carcinoma (HCC) after surgical resection.

Materials and methods

We retrospectively analyzed the results of TAI of W/O/W emulsion containing epirubicin for 18 consecutive patients with recurrent HCC after surgical resection. Fourteen patients were males and four were females; their ages ranged from 51 to 86 years (mean 69.8 years). TAI was repeated every 1–6 months based on the response of the tumor. A total of 41 TAI procedures were performed for 18 patients. Angiographically, recurrent HCC appeared a single nodule in nine patients and was multinodular in other nine patients. TAI was performed selectively in 27 procedures and non-selectively in 14 procedures. Maximum response within 3 months was rated as follows: a complete response (CR, complete disappearance of tumor and no evidence of new lesions); partial response (PR, a reduction of <50% in total volume of all tumors calculated from the two longest perpendicular diameters without a new lesion); no response (NC, a reduction of <50% in total volume or an increase of <25% without a new lesion); or progression of disease (PD, an increase of >25% in total volume or evidence of new lesions). Survival time was defined as the time from the date of first TAI to the date of death or last follow-up (median follow-up time: 17 months) and the survival curve was estimated using the Kaplan–Meier method.

Results

The CR rate was 33% and the effective response rate (CR rate + PR rate) was 78%. Survival from the time of initial TAI was 94% at 1 year, 76% at 2 years, and 76% at 3 years.

Conclusions

TAI of W/O/W emulsion may be an effective treatment for patients with recurrent HCC after surgical resection.

Bridging Hepatocellular Carcinoma to Transplant: Transarterial Chemoembolization Response,Tumor Biology,and Recurrence after Transplantation in a 12-Year Transplant Cohort

PurposeTo evaluate tumor response to transarterial chemoembolization as well as biologic characteristics of the tumor as predictors of recurrence after transplantation in patients with hepatocellular carcinoma (HCC) who were bridged or down-staged to liver transplantation.Materials and MethodsAn institutional review board-approved, Health Insurance Portability and Accountability Act-compliant, single-institution retrospective analysis was performed on all patients with HCC who were treated with the use of conventional transarterial chemoembolization or transarterial chemoembolization with drug-eluting embolics (DEE) over a 12-year period and who subsequently underwent liver transplantation (n = 142). Treatment response was based on modified Response Evaluation Criteria in Solid Tumors (mRECIST) imaging criteria and then correlated with tumor characteristics and recurrence. Of the 142 patients followed after transplantation, 127 had imaging after transarterial chemoembolization but before transplantation. Imaging response and post-transplantation recurrence were correlated with patient demographics, liver function, and tumor morphology. HCC recurred in 9 patients (mean time from transplantation, 526 days). Recurrence was analyzed with the use of univariate and multivariate statistics. Kaplan-Meier recurrence-free survival curves were calculated based on immediate imaging response before transplantation with the use of the log-rank test.ResultsBefore transplantation, 57% of patients (72/127) demonstrated complete response (CR) and 24% (31/127) showed partial response (PR). Complete pathologic necrosis occurred in 54% (39/72) of CR patients and 20% (6/31) of PR patients. Poor treatment response, defined as stable disease (SD) or progressive disease (PD), occurred in 18% of patients (24/127) before transplantation and was present in 67% of cases of recurrence (6/9; P < .001). Post-transplantation recurrence was present in 1.4% of patients (1/71) with CR and in 6.5% of patients (2/31) with PR. In patients with SD after transarterial chemoembolization, HCC recurred in 18.8% of transplant patients (3/16) and in 43% of patients (3/7) with PD. Larger pretreatment tumor size (P = .05), higher Child-Pugh score (P = .002), higher tumor grade at explantation (P = .04), and lymphovascular invasion at explantation (P = .008) also were associated with increased incidence of post-transplantation recurrence.ConclusionsPoor tumor response to transarterial chemoembolization before transplantation identifies patients at increased risk for post-transplantation recurrence.

Transarterial Chemoembolization Using 100-μm Drug-Eluting Microspheres in Patients with Hepatocellular Carcinoma: A Prospective Study and Midterm Follow-up

PurposeThe purpose of this study was to assess the safety and efficacy of drug-eluting embolic (DEE) transarterial chemoembolization for hepatocellular carcinoma (HCC) in patients who are ineligible for curative treatment, using doxorubicin-loaded Tandem (Varian Medical) microspheres.Materials and MethodsBetween October 2015 and December 2017, 98 patients with unresectable HCC (69 males, 29 females; mean age, 60.5 ± 10.0 years of age; and American Joint Committee on Cancer [AJCC] stage ≦T3a) treated with DEE transarterial chemoembolization using 100-μm doxorubicin-loaded microspheres were enrolled prospectively. All studies were reviewed and approved by the Institutional Review Board of Chang Gung Memorial Hospital. Dynamic contrast-enhanced computed tomography or magnetic resonance imaging 1 month after treatment was used for tumor response assessment according to the modified Response Evaluation Criteria in Solid Tumors (mRECIST). Outcomes included overall survival (OS), progression-free survival (PFS), and downstaging profile.ResultsMedian follow-up was 21.2 months. At follow-up examinations at 0.5-, 1-, 1.5- and 2.5-year follow-up, OS rates were 93.8%, 89.5%, 79.4%, and 77.0%, respectively. Complete response (CR), partial response, stable disease, and progressive disease were noted in 50 (51.0%), 23 (23.5%), 18 (18.4%), and 7 (7.1%) patients, respectively, with 93.9% disease control rate and 74.5% objective response rate. Mean OS was 28.7 months, and mean PFS was 19.6 months. Number of nodules >3, bilobar disease, larger tumor, and higher AJCC stage correlated with worse CR. No serious adverse events occurred after DEE transarterial chemoembolization. Successful downstage rate was 73.3% (22 of 30) and number of nodules predicting successful downstaging was 7 nodules (cutoff).ConclusionsTandem DEE transarterial chemoembolization provides safe and effective treatment for HCC and a bridge or downstage therapy for liver transplantation.
