Factors Contributing to the Prognosis after Second-line Therapy with Ramucirumab in Advanced Hepatocellular Carcinoma.

Objective Multiple therapeutic agents exist for advanced hepatocellular carcinoma (HCC), but prognostic factors in second-line and subsequent therapies are unclear. Ramucirumab is a molecular-targeted agent effective against hepatocytes with alpha-fetoprotein (AFP) >400 ng/mL after sorafenib failure. We examined the prognostic factors and efficacy of ramucirumab with prior therapy other than sorafenib. Methods In our retrospective multicenter study, 33 patients were treated with ramucirumab for HCC with prior therapy other than sorafenib, including 1 patient who received 2 lines of ramucirumab. We analyzed background factors, liver reserve, the prognosis, and treatment duration and efficacy. Results The median albumin-bilirubin (ALBI) value showed little change during ramucirumab treatment. The ALBI value improved in 32% of patients, and their prognoses were better than in those who did not improve. Response and efficacy rates were not as high as those in the REACH-2 study but were similar when limited to patients with 2,500 ng/mL AFP. Thirteen patients received further treatment after ramucirumab failure and they had a significantly better prognosis from ramucirumab administration and also had a significantly better prognosis from the start of the first tyrosine kinase inhibitor than who did not received further treatment. In univariate and multivariate analyses of prognostic factors, the continuation of treatment with another drug after ramucirumab failure and a good ALBI value at initiation were significant. The presence of a ramucirumab response and treatment duration were not associated with the prognosis. A good ALBI value at initiation and ALBI value improvement during treatment were also identified as independent factors associated with eligibility for further treatment after ramucirumab failure. The treatment line did not correlate with the availability of treatment with another drug after treatment failure. Conclusions ALBI value improvement with ramucirumab treatment allows for subsequent treatment after failure and an improved overall prognosis.

Indicators of sorafenib efficacy in patients with advanced hepatocellular carcinoma.

AIM: To determine significant indicators for the efficacy of sorafenib in patients with advanced hepatocellular carcinoma (HCC). METHODS: A total of 46 patients with Barcelona Clinic Liver Cancer stage C who received sorafenib for more than 30 d at the Iizuka Hospital from June 2009 to December 2012 were enrolled in this study. Multivariate and univariate analyses were performed to evaluate the associations of hepatic function according to Child-Pugh grade, location and size of the largest tumor and adverse events of sorafenib treatment, such as hand-foot syndrome (HFS), hypertension, diarrhea, and alopecia, with the efficacy of treatment, as measured by overall survival (OS) and time to progression (TTP). RESULTS: Patients included 39 men and 7 women whose ages ranged from 48 to 85 years (70.6 ± 9.6 years). HCC was classified according to etiology as follows: hepatitis C virus (n = 26), hepatitis B virus (n = 9), and other (n = 11). Liver function in patients was categorized as Child-Pugh grade A (n = 30) or B (n = 16). Tumors were categorized by size [< 5 cm (n = 33) or >5 cm (n = 13)] and the location of the largest tumor was used to categorize patients with intrahepatic (n = 28) or extrahepatic (n = 18) HCC. HFS, hypertension, diarrhea, and alopecia were present in 22 (47.8%), 19 (41.3%), 15 (32.6%) and 7 patients (15.2%), respectively. The median OS of all patients was 373 d and the median TTP was 112 d. The etiology of HCC did not correlate with the median OS and TPP. The median OS of patients with tumors < 5 cm was significantly longer than those with larger tumors (496 vs 245 d; HR = 0.19, 95%CI: 0.07-0.48; P < 0.01). According to the results of a multivariate analysis, the size of the largest tumor affected OS (HR = 0.22, 95%CI: 0.08-0.59; P < 0.01). The median TTP was significantly longer in patients with extrahepatic compared to intrahepatic major HCC (224 vs 98 d; HR = 0.32; 95%CI: 0.14-0.67; P < 0.01). The median TTP of patients with HFS was significantly longer than those without it (195 d vs 83 d; HR = 0.41, 95%CI: 0.20-0.82; P < 0.05), and the median TTP was significantly longer in patients with hypertension (195 d vs 84 d; HR = 0.43, 95%CI: 0.21-0.84; P < 0.05). According to the results of the multivariate analysis, extrahepatic major HCC (HR = 0.36, P < 0.01) and HFS (HR = 0.44, P < 0.05) prolonged TTP. CONCLUSION: Extrahepatic major HCC and HFS are associated with prolonged TTP and are useful indicators for judging the efficacy of sorafenib treatment.
