Simple Scoring System for Predicting TACE Unsuitable among Intermediate-Stage Hepatocellular Carcinoma Patients in the Multiple Systemic Treatment Era.

BACKGROUND/AIM: With the development of systemic treatment methods for unresectable hepatocellular carcinoma (uHCC), the concept of unsuitable for transcatheter arterial chemoembolization (TACE) has become important. This study aimed to establish a simple predictive scoring system for determining TACE unsuitable status. MATERIALS/METHODS: From 1998 to 2015, 196 patients with intermediate-stage uHCC with Child-Pugh A (score 5:6 = 108:88) and given TACE as the initial treatment were enrolled. At the baseline, tumor burden (Milan criteria-out, up-to-7 in/out, and up-to-11 in/out: 0-2 points) and modified albumin-bilirubin grade 1/2a or 2b (0-1 point) were added to determine the score for TACE unsuitable (CITRUS-MICAN score; low <2 and high ≥2). In addition, a previously reported tumor marker (TM) score, in which alpha-fetoprotein (AFP) was ≥100 ng/mL, fucosylated AFP ≥10%, and des-gamma-carboxy prothrombin ≥100 mAU/mL (each 1 point) (total 0, 1, or ≥2 points), was used for additionally evaluating tumor malignancy potential. Prognosis was retrospectively evaluated based on those scores. RESULTS: Median survival time (MST) was better for low compared to high CITRUS-MICAN score (42.0 vs. 26.4 months) (p = 0.002). A 2-step evaluation using the combination of CITRUS-MICAN and TM scores showed an MST of 43.2 months for low CITRUS-MICAN/TM score 0/1 (rank-A) and 39.6 months for low CITRUS-MICAN/TM score ≥2 (rank-B2), while it was 46.8 months for high CITRUS-MICAN/TM score 0 (rank-B1), 28.8 months for high CITRUS-MICAN/TM score 1 (rank-B2), and 22.8 months for high CITRUS-MICAN/TM score ≥2 (rank-C). For rank-A cases (n = 51), MST was 43.2 months, while it was 46.8 months for rank-B1 (n = 12), 31.2 months for rank-B2 (n = 82), and 22.8 months for rank-C (n = 51) (p = 0.001). CONCLUSION: The results showed that rank-C indicates absolute TACE unsuitable status. For rank-A patients, good prognosis with TACE can be expected, while TACE refractoriness status during the clinical course should be carefully evaluated so as to anticipate the appropriate timing for switching to systemic treatment in rank-B1 and -B2 patients.

Randomized, phase II trial of sequential hepatic arterial infusion chemotherapy and sorafenib versus sorafenib alone as initial therapy for advanced hepatocellular carcinoma: SCOOP-2 trial.

BACKGROUND: The efficacy of hepatic arterial infusion chemotherapy (HAIC) for advanced hepatocellular carcinoma (HCC) remains unclear. We conducted a multi-center randomized phase II study comparing a sequential HAIC-sorafenib regimen versus sorafenib alone as an initial therapy for HCC. METHODS: Patients were randomly assigned (ratio, 1:1) to receive sequential HAIC with cisplatin followed by sorafenib (HAIC group, n = 35) or sorafenib alone (sorafenib group, n = 33) as an initial therapy. The primary endpoint was the one-year survival rate. Secondary endpoint included overall survival (OS), the 2-year survival rate, the time-to-progression (TTP), the objective response rate (ORR), the disease control rate (DCR), and safety. RESULTS: For the primary endpoint, the one-year survival rates were 46% in the HAIC group and 58% in the sorafenib group. The median OS period was 10.0 months (95% CI, 7.0-18.8) in the HAIC group and 15.2 months (95% CI, 8.2-19.7) in the sorafenib group (hazard ratio [HR], 1.08; 95% CI, 0.63 to 1.86, P = 0.78). The median TTP, ORR and DCR in the HAIC group were 2.8 months (95% CI, 1.7-5.5), 14.3, and 45.7%, respectively, while those in the sorafenib group were 3.9 months (95% CI, 2.3-6.8), 9.1, and 45.5%, respectively. No unexpected adverse events related to HAIC or sorafenib were observed in either group. CONCLUSIONS: Sequential HAIC with cisplatin and sorafenib does not improve the survival benefit, compared with sorafenib alone, when used as an initial therapy for advanced HCC. However, this study was underpowered in regard to its primary and secondary endpoints, so the results should be interpreted with caution.

Impact of the Prognostic Nutritional Index on the Survival of Japanese Patients with Hepatocellular Carcinoma Treated with Sorafenib: A Multicenter Retrospective Study.

Objective The purpose of this multicenter retrospective study was to investigate the impact of the prognostic nutritional index (PNI) on the survival of Japanese patients with hepatocellular carcinoma (HCC) treated with sorafenib. Methods A total of 178 HCC patients from May 2009 to December 2015 at our affiliated hospitals was included in this study. The PNI was calculated as follows: 10×serum albumin (g/dL) +0.005×total lymphocyte count (per mm3). The patients were divided into two groups according to the cut-off value of the PNI and as calculated by a receiver operating characteristic curve analysis. Results The optimum cut-off value of the PNI was set at 46.8. We defined the 33 patients with a PNI≥46.8 as the PNI-high group and the 145 patients with a PNI<46.8 as the PNI-low group. The response rate was 20.0% in the PNI-high group and 8.1% in the PNI-low group, without any statistically significance (p=0.09). The duration of sorafenib therapy and the overall survival in the PNI-high group were significantly better than those in the PNI-low group. The PNI-high group was thus found to be a predictive factor associated with the duration of sorafenib therapy [hazard ratio (HR) 0.58; 95% confidence interval (CI) 0.39-0.87, p=0.008] and overall survival (HR 0.62; 95% CI 0.39-0.99, p=0.046) in a multivariate analysis. Conclusion The PNI is a simple and useful marker for predicting the survival of patients with HCC treated with sorafenib.

ß-Hydroxy-ß-methyl Butyrate/L-Arginine/L-Glutamine Supplementation for Preventing Hand-Foot Skin Reaction in Sorafenib for Advanced Hepatocellular Carcinoma.

BACKGROUND/AIM: Sorafenib is standard treatment for advanced hepatocellular carcinoma (HCC). Hand-foot skin reaction (HFSR) is a notorious side-effect of this therapy. This study evaluated prophylactic benefits of an oral nutritional supplement (ONS) on sorafenib-associated HFSR in advanced HCC. PATIENTS AND METHODS: This was a prospective, single-center, open-label trial arm using combined ONS and sorafenib in patients with unresectable HCC from August 2014 to February 2018. Control patients received sorafenib without ONS from 2011 to 2014. From September 2014, prophylactic ONS containing ß-hydroxy-ß-methylbutyrate (HMB), L-arginine, and L-glutamine was given. Sorafenib dosage was 400 mg/day for both groups. RESULTS: Each group comprised 22 men and three women. Age, sex, Child-Pugh score, and clinical stage excluding IV-B did not significantly differ between the groups. HFSR occurred after 2 weeks: 15/25 patients in the control group (60%; HFSR grade 1: 6, grade 2: 7, grade 3: 2) vs. 8/25 in the ONS group (32%; HFSR grade 1: 4, grade 2: 4, grade 3: 0; p=0.047, Pearson's Chi-square test). CONCLUSION: Prophylactic HMB, L-arginine and L-glutamine supplementation effectively prevented sorafenib-associated HFSR in patients with advanced HCC.

[A case of advanced hepatocellular carcinoma effectively treated with 5-fluorouracil and high-concentration cisplatin suspended in lipiodol by short-term hepatic arterial infusion chemotherapy].

A 75-year-old Japanese man was admitted to our hospital for treatment of advanced hepatocellular carcinoma (HCC) with HCV-related liver cirrhosis. He had been treated earlier with transarterial chemoembolization (TACE) in both another and our own hospital before this admission. At this time, abdominal CT revealed multiple HCCs (maximum 4.0 cm in diameter) located in hepatic S6, S5, and S8. An infused port system had been subcutaneously implanted, and he was treated with hepatic arterial infusion chemotherapy with 3 days' FPL (5-FU at a dose of 500 mg/m2 on days 1-3 and cisplatin (CDDP/IA call)-Lipiodol (LPD) suspension (10 mg/mL) at a dose of 50 mg/body on day 2) every 6-10 weeks. He was also treated with selective TACE for HCC that was supplied by extra-hepatic arterial branches. He had been treated with 3 courses of 3 days' FPL, and the selective TACE, HCCs in S6, S5 and S8 disappeared completely and multiple HCCs almost entirely vanished. During the 3-day treatment with FPL, his performance status (PS) was maintained and no severe side effects were observed. Although multiple recurrent HCC is potentially fatal and QOL is lost, hepatic arterial infusion chemotherapy with 3 days' FPL was effective and contributed to improve the patient's prognosis and QOL.
