Hepatic Arterial Infusion Chemotherapy With Folfirinox or Oxaliplatin Alone in Metastatic Colorectal Cancer.

ABSTRACT:

Background

Hepatic arterial infusion (HAI) of chemotherapy is an option for the treatment of patients with liver metastases from colorectal cancer (LMCRC). Though HAI with oxaliplatin (HAI-Ox) is generally used, intravenous (IV) 5-fluoro-uracil (5FU)-oxaliplatin-irinotecan HAI (HAI-Folfirinox) is feasible and leads to curative-intent surgery in 30% of pretreated patients. We compared the efficacy and safety of HAI-Ox and HAI-Folfirinox.

Methods

Patients who underwent HAI chemotherapy for LMCRC were retrospectively included from 2008 to 2019 from six French expert centers.

Results

Data were collected from 273 previously treated patients with LMCRC. Patients received HAI-Folfirinox (n = 52) or HAI-Ox (n = 221) combined with IV chemotherapy. The objective response rate (ORR) was 43.2% in patients with HAI-Folfirinox and 45.9% (ns) in patients with HAI-Ox. Median overall survival (OS) was 17 months (95% CI: 15-32.3) with HAI-Folfirinox and 26.2 months (95% CI: 19.4-34.4; p = 0.1) with HAI-Ox. Median progression-free survival (PFS) was 7.9 months (95% CI: 4.9-10.3) with HAI-Folfirinox and 6.4 months (95% CI: 6.0-7.7; p = 0.6) with HAI-Ox. The secondary liver resection rate was 35.6% with HAI-Folfirinox and 16.7% with HAI-Ox (p = 0.007). Grade 2 and above toxicities were significantly more frequent with HAI-Folfirinox. In the global population, only 2 factors were prognostic for OS in multivariable analyses: liver-only disease [hazard ratio (HR): 0.4; 95% CI 0.20-0.83; p = 0.013] and local complications of the catheter (HR: 3.8; 95% CI 1.6-9.0; p = 0.002).

Conclusion

Hepatic arterial infusion results in high response rates, secondary resections, and long survival in pretreated patients with LMCRC.

Project description:BackgroundLenvatinib is the first-line treatment for advanced hepatocellular carcinoma, but prognosis is still unsatisfactory. Recently, hepatic arterial infusion chemotherapy (HAIC), and immune checkpoint inhibitors showed promising results for advanced hepatocellular carcinoma. Considering different anti-malignancy mechanisms, combining these three treatments may improve outcomes. This study aimed to compare the efficacy and safety of lenvatinib, toripalimab, plus HAIC versus lenvatinib for advanced hepatocellular carcinoma.MethodsThis was a retrospective study including patients treated with lenvatinib [8 mg (⩽60 kg) or 12 mg (>60 kg) once daily] or lenvatinib, toripalimab plus HAIC [LeToHAIC group, lenvatinib 0-1 week prior to initial HAIC, 240 mg toripalimab 0-1 day prior to every HAIC cycle, and HAIC with FOLFOX regimen (oxaliplatin 85 mg/m2, leucovorin 400 mg/m2, 5-fluorouracil bolus 400 mg/m2 on day 1, and 5-fluorouracil infusion 2400 mg/m2 for 46 h, every 3 weeks)]. Progression-free survival, overall survival, objective response rate, and treatment-related adverse events were compared.ResultsFrom February 2019 to August 2019, 157 patients were included in this study: 71 in the LeToHAIC group and 86 in the lenvatinib group. The LeToHAIC group showed longer progression-free survival (11.1 versus 5.1 months, p < 0.001), longer overall survival (not reached versus 11 months, p < 0.001), and a higher objective response rate (RECIST: 59.2% versus 9.3%, p < 0.001; modified RECIST: 67.6% versus 16.3%, p < 0.001) than the lenvatinib group. In addition, 14.1% and 21.1% of patients in the LeToHAIC group achieved complete response of all lesions and complete response of the intrahepatic target lesions per modified RECIST criteria, respectively. Grade 3/4 treatment-related adverse events that were more frequent in the LeToHAIC group than in the lenvatinib group included neutropenia (8.5% versus 1.2%), thrombocytopenia (5.6% versus 0), and nausea (5.6% versus 0).ConclusionsLenvatinib, toripalimab, plus HAIC had acceptable toxic effects and might improve survival compared with lenvatinib alone in advanced hepatocellular carcinoma.

Project description:ImportanceSorafenib is the first-line treatment for hepatocellular carcinoma with portal vein invasion; however, it has shown unsatisfactory survival benefit. Sorafenib plus hepatic arterial infusion chemotherapy (HAIC) of oxaliplatin, fluorouracil, and leucovorin (FOLFOX) has shown promising results for these patients in a previous phase 2 study.ObjectiveTo investigate the efficacy and safety of sorafenib plus HAIC compared with sorafenib for hepatocellular carcinoma with portal vein invasion.Design, setting, and participantsThis randomized, open-label clinical trial enrolled 818 screened patients. Of the 818 participants, 247 with hepatocellular carcinoma and portal vein invasion were randomly assigned (1:1) via a computer-generated sequence to receive sorafenib plus HAIC or sorafenib. This trial was conducted at 5 hospitals in China and enrolled patients from April 1, 2016, to October 10, 2017, with a follow-up period of 10 months.InterventionsRandomization to receive 400 mg sorafenib twice daily (sorafenib group) or 400 mg sorafenib twice daily plus HAIC (SoraHAIC group) (oxaliplatin 85 mg/m2, leucovorin 400 mg/m2, fluorouracil bolus 400 mg/m2 on day 1, and fluorouracil infusion 2400 mg/m2 for 46 hours, every 3 weeks).Main outcomes and measuresThe primary endpoint was overall survival by intention-to-treat analysis. Safety was assessed in patients who received at least 1 dose of study treatment.ResultsFor 247 patients (median age, 49 years; range, 18-75 years; 223 men and 24 women), median overall survival was 13.37 months (95% CI, 10.27-16.46) in the SoraHAIC group vs 7.13 months (95% CI, 6.28-7.98) in the sorafenib group (hazard ratio [HR], 0.35; 95% CI, 0.26-0.48; P < .001). The SoraHAIC group showed a higher response rate than the sorafenib group (51 [40.8%] vs 3 [2.46%]; P < .001), and a longer median progression-free survival (7.03 [95% CI, 6.05-8.02] vs 2.6 [95% CI, 2.15-3.05] months; P < .001). Grade 3/4 adverse events that were more frequent in the SoraHAIC group than in the sorafenib group included neutropenia (12 [9.68%] vs 3 [2.48%]), thrombocytopenia (16 [12.9%] vs 6 [4.96%]), and vomiting (8 [6.45%] vs 1 [0.83%]).Conclusions and relevanceSorafenib plus HAIC of FOLFOX improved overall survival and had acceptable toxic effects compared with sorafenib in patients with hepatocellular carcinoma and portal vein invasion.Trial registrationClinicalTrials.gov identifier: NCT02774187.
