Complete Response for Advanced Hepatocellular Carcinoma by Conversion Surgery Therapy Following a Good Response of Regorafenib Despite Rapid Progressive Disease with Sorafenib.

A 68-year-old man with hepatocellular carcinoma (HCC) visited his previous hospital due to abdominal pain and was diagnosed with ruptured HCC. Before visiting our hospital, he underwent HCC treatment at his previous hospital, but his tumors did not improve. Although he started treatment with sorafenib, the tumors rapidly grew. Subsequently, regorafenib was given, and the tumors shrank. After 22 months being treated with regorafenib, HCC reoccurred, with a new lung metastasis and a contrast-enhanced nodule on the peritoneal dissemination appearing. He underwent conversion surgery and survived for 4.5 years after his HCC was diagnosed.

Comparison of the Clinical Outcome of Ramucirumab for Unresectable Hepatocellular Carcinoma with That of Prior Tyrosine Kinase Inhibitor Therapy.

INTRODUCTION: The clinical outcome of ramucirumab in multi-molecular targeted agent (MTA) sequential therapy for unresectable hepatocellular carcinoma (u-HCC) was assessed in comparison with that of prior tyrosine kinase inhibitor (TKI) therapy. METHODS: Sixteen patients who received ramucirumab as part of multi-MTA sequential therapy for u-HCC were enrolled in a retrospective, cohort study. Ramucirumab was started as 2nd line in 7 patients, 3rd line in 5 patients, and 4th line in 4 patients. RESULTS: The overall response rate was 6.3%, the disease control rate (DCR) was 50.0%, median progression-free survival was 2.0 months (evaluated by mRECIST), median overall survival (OS) with ramucirumab was 7.9 months, and the median OS from 1st-line therapy was 28.1 months. One month after the start of ramucirumab, α-fetoprotein (AFP) decreased in 6 of 12 cases (50.0%), and the DCR in AFP-decreased cases was 83.3%. The DCR of ramucirumab was 66.7% in cases in which disease control was obtained by prior TKI therapy, whereas it was 0.0% in the cases in which disease control was not obtained by prior TKI therapy. Examining the adverse events, no new safety concerns were confirmed. CONCLUSION: The AFP response to ramucirumab and the treatment response to prior TKI therapy are associated with treatment response to ramucirumab.

Analysis of Post-Progression Survival in Patients with Unresectable Hepatocellular Carcinoma Treated with Lenvatinib.

BACKGROUND: Although a strong antitumor effect of lenvatinib (LEN) has been noted for patients with unresectable hepatocellular carcinoma (HCC), there are still no reports on the prognosis for patients with disease progression after first-line LEN therapy. METHODS: Patients (n = 141) with unresectable HCC, Child-Pugh class A liver function, and an Eastern Cooperative Oncology Group performance status (ECOG-PS) of 0 or 1 who were treated with LEN from March 2018 to December 2019 were enrolled. RESULTS: One hundred and five patients were treated with LEN as first-line therapy, 53 of whom had progressive disease (PD) at the radiological evaluation. Among the 53 patients with PD, there were 27 candidates for second-line therapy, who had Child-Pugh class A liver function and an ECOG-PS of 0 or 1 at progression. After progression on first-line LEN, 28 patients were treated with a molecular targeted agent (MTA) as second-line therapy (sorafenib: n = 26; ramucirumab: n = 2). Multivariate analysis identified modified albumin-bilirubin grade 1 or 2a at LEN initiation (odds ratio 5.18, 95% confidence interval [CI] 1.465-18.31, p = 0.011) as a significant and independent factor for candidates. The median post-progression survival after PD on first-line LEN was 8.3 months. Cox hazard multivariate analysis showed that a low alpha-fetoprotein level (<400 ng/mL; hazard ratio [HR] 0.297, 95% CI 0.099-0.886, p = 0.003), a relative tumor volume <50% at the time of progression (HR 0.204, 95% CI 0.07-0.592, p = 0.03), and switching to MTAs as second-line treatment after LEN (HR 0.299, 95% CI 0.12-0.746, p = 0.01) were significant prognostic factors. CONCLUSION: Among patients with PD on first-line LEN, good liver function at introduction of LEN was an important and favorable factor related to eligibility for second-line therapy. In addition, post-progression treatment with MTAs could improve the prognosis for patients who had been treated with first-line LEN.

Clinical outcome of sorafenib treatment in patients with advanced hepatocellular carcinoma refractory to hepatic arterial infusion chemotherapy.

BACKGROUND AND AIM: It has been reported about poor prognosis in patients with advanced hepatocellular carcinoma (HCC) refractory to hepatic arterial infusion chemotherapy (HAIC). We assessed the survival benefits of sorafenib therapy for advanced HCC in HAIC refractory patients. METHODS: The study subjects were 191 patients with advanced HCC who had been treated with HAIC. Sorafenib was used in 27 patients who finally failed to respond to HAIC (HAIC/sorafenib group). Clinical outcome was compared between HAIC/sorafenib and HAIC alone groups. RESULTS: There were no significant differences in clinical characteristics and response rate of HAIC between the two groups (response rate: 25.9%, HAIC/sorafenib group; 30.4%, HAIC alone group). The median survival time (MST) for all patients was 11.0 months. The survival rate was significantly higher in the HAIC/sorafenib group than HAIC alone group (MST 22.2 vs 8.7 months, P = 0.017). From administration sorafenib, the disease control rate was 51.8% with MST of 10.4 months. Among HAIC non-responders, the survival rate was significantly higher in the HAIC/sorafenib group than HAIC alone group. Multivariate analysis identified additional therapy with sorafenib as significant and independent determinant of overall survival in all patients and HAIC non-responders. CONCLUSION: Additional therapy with sorafenib could probably improve the prognosis of HAIC refractory patients.
