Transarterial embolization and low-dose continuous hepatic arterial infusion chemotherapy with oxaliplatin and raltitrexed for hepatocellular carcinoma with major portal vein tumor thrombus

Lung metastases after liver cancer resection cured by immunotherapy: case report and literature review

The lung is the most common metastatic organ of primary liver cancer, accounting for 39.5-53.8% of extrahepatic metastasis, which seriously affects the prognosis of patients. In clinical treatment, it is difficult for one therapeutic schedule to achieve the desired effect sometimes, requiring two or even several combined methods for liver cancer lung metastasis. In this study, we report a liver cancer patient with lung metastases who received various combined therapies. However, the comprehensive treatment did not improve the patient's pulmonary metastasis symptoms until after the application of immunotherapy, and the lung metastases were gradually cured.

Hepatic Arterial Infusion Chemotherapy with Oxaliplatin Plus Raltitrexed as an Alternative Option in Advanced Hepatocellular Carcinoma Patients with Failure of, or Unsuitability for, Transarterial Chemoembolization

Background and Objectives: To assess the efficacy and safety of hepatic arterial infusion chemotherapy (HAIC) with oxaliplatin plus raltitrexed (HAICROX) as an alternative treatment option for advanced hepatocellular carcinoma (HCC) patients who are ineligible for, or failed, the transarterial chemoembolization (TACE) treatment. Materials and Methods: From July 2020 to November 2021, a total of 35 HCC patients were enrolled and received HAIC with oxaliplatin plus raltitrexed. The overall survival (OS) and time to progression (TTP) were primary and secondary endpoints, respectively. The tumor response was assessed by the modified response evaluation criteria in solid tumors (mRECIST), and the adverse events were investigated using the common terminology criteria for adverse events version 5.0 (CTCAE 5.0). Results: The median OS and TTP were 10 months (95% confidence interval (CI): 5.5-14.6) and 3.5 months (95% CI: 2.3-4.7), respectively. By means of multivariate analysis, anti-programmed cell death protein 1 (anti-PD-1) immunotherapy was found to be an independent prognostic factor for better survival. No patients experienced toxicity-related death. Thrombocytopenia, alanine aminotransferase (ALT), and aspartate aminotransferase (AST) elevation were the most common toxicities. No grade 3 or higher adverse events related to HAICROX were observed. Conclusion: HAICROX showed valuable efficacy and tolerable toxicity in advanced HCC patients who progressed on TACE or were ineligible for TACE. HAICROX is a promising treatment for advanced-stage HCC patients with TACE failure or ineligibility.

Real-world study of hepatic artery infusion chemotherapy combined with anti-PD-1 immunotherapy and tyrosine kinase inhibitors for advanced hepatocellular carcinoma

Aim: We investigated the efficacy and safety of hepatic artery infusion chemotherapy (HAIC) combined with anti-PD-1 immunotherapy and tyrosine kinase inhibitors (TKIs) for advanced hepatocellular carcinoma (HCC). Method: This retrospective study included HCC patients treated with HAIC, TKIs and anti-PD-1 antibodies between May 2019 and November 2020 in our hospital. Primary end points were progression-free survival and safety. Results: Twenty-seven advanced HCC patients were analyzed. The median follow-up was 12.9 months (range: 4.0-24.0 months) and the median progression-free survival was 10.6 months. The objective response rate and disease control rate were 63.0 and 92.6%, respectively. No treatment-related deaths occurred. Conclusion: In patients with advanced HCC, treatment with HAIC, anti-PD-1 antibodies and oral TKIs was effective and safe.

Combination Therapy of Chemoembolization and Hepatic Arterial Infusion Chemotherapy in Hepatocellular Carcinoma with Portal Vein Tumor Thrombosis Compared with Chemoembolization Alone: A Propensity Score-Matched Analysis

Background

Survival of patients with portal vein tumor thrombosis (PVTT) is extremely poor; transarterial chemoembolization (TACE) is a treatment for patients with HCC and PVTT. Some studies showed that hepatic arterial infusion chemotherapy (HAIC) might improve the survival of HCC with PVTT. There were few researches of combining TACE with HAIC for patients with HCC and PVTT.

Aim

This study was aimed at comparing overall survival (OS) and progression-free survival (PFS) following treatment with conventional transarterial chemoembolization plus hepatic arterial infusion chemotherapy (cTACE-HAIC) or conventional transarterial chemoembolization (cTACE) alone in patients with hepatocellular carcinoma (HCC) and portal vein tumor thrombosis (PVTT).

Methods

From January 2011 to December 2016, 155 patients with HCC and PVTT who received cTACE-HAIC (cTACE-HAIC group) (n = 86) or cTACE alone (cTACE group) (n = 69) were retrospectively evaluated. Propensity score matching (PSM) reduced the confounding bias and yielded 60 matched patient pairs. The tumors' responses were evaluated using the modified response evaluation criteria in solid tumors (mRECIST). OS and PFS of groups were compared using the Kaplan-Meier method, log-rank test, and Cox proportional hazard regression models.

Results

The median follow-up duration was 93 months (range: 1-93 months). The cTACE-HAIC group's OS (9.0 months) and PFS (6.0 months) were significantly longer than the cTACE group's OS (5.0 months) and PFS (2.0 months) (p = 0.018 and p = 0.045, respectively) in the matched cohort. Multivariate analyses showed that cTACE-HAIC was independently associated with OS (hazard ratio (HR) 0.602, p = 0.010) and PFS (HR 0.66, p = 0.038). The matched groups did not differ regarding grade 3 or 4 adverse events.

Conclusion

cTACE-HAIC was superior to cTACE alone regarding OS and PFS in patients with HCC and PVTT. Treatment-associated toxicities were generally well tolerated.

Comparison of transcatheter arterial chemoembolization with raltitrexed plus liposomal doxorubicin vs. tegafur plus pirarubicin for unresectable hepatocellular carcinoma

Background

There is still no general consensus on the optimal chemotherapeutic agent selection for transcatheter arterial chemoembolization (TACE) in unresectable hepatocellular carcinoma (HCC). The present study aimed to compare the efficacy and safety of TACE with raltitrexed plus liposomal doxorubicin (R + PGLD) vs. tegafur plus pirarubicin (T + P) in patients with unresectable HCC.

Methods

A total of 148 patients with unresectable HCC treated with TACE between January 2012 and December 2016 were retrospectively analyzed. Of them, 74 patients were in the R + PGLD group and 74 patients were in the T + P group (1:1). The treatment response of the tumor, overall survival (OS) time, and adverse effects were compared between the two groups.

Results

There were no significant differences in patient characteristics or embolization effect (lipiodol deposition) between the two groups (P>0.05). R + PGLD treatment had a better clinical efficacy than T + P treatment (OR: 64.9% vs. 45.9%, P=0.031; DC: 89.2% vs. 74.3%, P=0.032). Portal vein invasion, hepatic vein invasion, tumor size and BCLC stage were associated with OR or DC after TACE using R + PGLD treatment. Survival analysis revealed that patients who received TACE with R + PGLD had a better prognosis than those treated with T + P. Moreover, some complications in the R + PGLD group, including vomiting, myelosuppression and cardiotoxicity, were significantly lower than those in the T + P group (P<0.05).

Conclusions

TACE with raltitrexed and liposomal doxorubicin could reduce the incidence of adverse reactions and significantly improve the OS of patients with unresectable HCC.

Sorafenib combined with embolization plus hepatic arterial infusion chemotherapy for inoperable hepatocellular carcinoma

BACKGROUND

There is little evidence of combining sorafenib with hepatic arterial infusion chemotherapy (HAIC) after transarterial chemoembolization (TACE) for intermediate and advanced hepatocellular carcinoma (HCC). It is important to identify that patients with intermediate and advanced HCC are most likely to benefit from this combination therapy.

AIM

To investigate the safety and clinical outcomes of sorafenib combined with HAIC with folinic acid, 5-fluorouracil (5-FU), and oxaliplatin (FOLFOX) after TACE for intermediate and advanced HCC.

METHODS

This prospective phase II study enrolled patients with intermediate and advanced HCC who underwent treatment with sorafenib combined with TACE-HAIC. All patients initially received the standard 400 mg dose of sorafenib twice daily before TACE-HAIC. Participants at our institute with intermediate and advanced HCC underwent routine TACE. Then, the catheter used for embolization was kept in place in the hepatic artery, and oxaliplatin was intra-arterially administered for 6 h, followed by 5-FU for 18 h, and folinic acid was intravenously administered for 2 h. The primary endpoints were safety, as evaluated by the Common Terminology and Criteria for Adverse Events version 4.0, and 12-mo progression-free survival (PFS), as analyzed by the Kaplan-Meier method. As secondary endpoints, the objective response rate (ORR) was evaluated by the modified Response Evaluation Criteria for Solid Tumors, and survival time [overall survival (OS)] was analyzed by the Kaplan-Meier method.

RESULTS

Sixty-six participants at our institute with intermediate and advanced HCC were enrolled in this prospective study (mean age, 53.3 ± 11.7 years). Approximately 56.1% of participants had Barcelona Clinic Liver Cancer (BCLC) stage C disease, and 43.9% had BCLC stage B disease. The ORR was 42.4%. The disease control rate was 87.9%. The grade 3-4 toxicities consisted of thrombocytopenia (4.5%), neutropenia (3.0%), and elevated aspartate aminotransferase (12.2%). Hand-foot skin reaction was also observed (40.9%). The median PFS was 13.1 mo (13.5 mo in the BCLC stage B participants and 9.4 mo in the BCLC stage C participants). The 6-mo, 12-mo, and 24-mo PFS rates were 75.0%, 54.7%, and 30.0%, respectively. The median OS was 21.8 mo.

CONCLUSION

Sorafenib combined with HAIC (FOLFOX) after TACE may be a feasible treatment choice for intermediate and advanced HCC because this treatment met the prespecified endpoint of a 6-mo PFS rate exceeding 50% and had good patient tolerance. Prospective randomized controlled trials are needed to confirm the effect of this combination therapy.

Safety and efficacy of hepatic arterial infusion chemotherapy with raltitrexed and oxaliplatin post-transarterial chemoembolization for unresectable hepatocellular carcinoma

Objective

To investigate the safety, efficacy, and prognostic factors of hepatic arterial infusion chemotherapy (HAIC) with raltitrexed and oxaliplatin post-transarterial chemoembolization (TACE) for unresectable hepatocellular carcinoma (uHCC).

Methods

Thirty-seven patients with uHCC who received HAIC with raltitrexed and oxaliplatin post-TACE between June 2014 and December 2016 at our hospital were recruited. The primary endpoint was overall survival (OS), and secondary endpoint was progression-free survival (PFS). The overall response rate (ORR) was evaluated using the modified Response Evaluation Criteria in Solid Tumors. Toxicity was assessed according to the Common Terminology Criteria for Adverse Events (v4.0). The OS and prognostic factors were analyzed using the Kaplan–Meier method, log-rank test, and Cox regression models.

Results

Three (8.1%) patients achieved complete response, 17 (46.0%) patients achieved partial response, and the ORR was54.0%.The median OS and median PFS were 19.0 months and 12.0 months, respectively. The common toxicities included grade 3–4 increased aspartate aminotransferase levels (8/37,21.6%), grade 1–2 hyperbilirubinemia (75.7%, 28/37), nonspecific abdominal pain and fever, and grade 2–3 thrombocytopenia (18.9%, 7/37); no patients developed grade 3–4 neutropenia. Univariate analysis showed that the tumor diameter (≤50 mm, p = 0.028), Barcelona Clinic Liver Cancer (BCLC) stage (p = 0.012), hepatitis B virus DNA level (p = 0.033), and derived neutrophil-to-lymphocyte ratio (dNLR; derived neutrophils/leukocytes minus neutrophils) (p = 0.003) were predictive factors for prognosis. Multivariate analysis showed that patients with BCLC stage B disease (p = 0.029) and dNLR≤2 before therapy (p = 0.004) had better prognosis.

Conclusions

HAIC with raltitrexed and oxaliplatin post-TACE is a safe and efficacious therapy for patients with uHCC; in particular, those with BCLC stage B and dNLR≤2 have better prognosis.
