Abstract
Pirarubicin (THP) is a new generation of cell cycle non-specific anthracycline-based anticancer drug. In the clinic, THP and THP combination therapies have been shown to be effective in hepatocellular carcinoma (HCC) patients with transcatheter arterial chemoembolization (TACE) without serious side effects. However, drug resistance limits its therapeutic efficacy. Berberine (BBR), an isoquinoline alkaloid, has been shown to possess antitumour properties against various malignancies. However, the synergistic effect of BBR and THP in the treatment of HCC is unknown. In the present study, we demonstrated for the first time that BBR sensitized HCC cells to THP, including enhancing THP-induced growth inhibition and apoptosis of HCC cells. Moreover, we found that BBR sensitized THP by reducing the expression of autophagy-related 4B (ATG4B). Mechanistically, the inhibition of HIF1α-mediated ATG4B transcription by BBR ultimately led to attenuation of THP-induced cytoprotective autophagy, accompanied by enhanced growth inhibition and apoptosis in THP-treated HCC cells. Tumor-bearing experiments in nude mice showed that the combination treatment with BBR and THP significantly suppressed the growth of HCC xenografts. These results reveal that BBR is able to strengthen the killing effect of THP on HCC cells by repressing the ATG4B-autophagy pathway, which may provide novel insights into the improvement of chemotherapeutic efficacy of THP, and may be conducive to the further clinical application of THP in HCC treatment.

Abstract
Pirarubicin (THP) is a new generation cell cycle nonspecific anthracycline anticancer drug. Pirarubicin and pirarubicin-based combination therapies have been demonstrated to be effective against HCC in TACE. However, the drug resistance limits its therapeutic efficacy. Receptor-interacting protein kinase 1 (RIPK1) displays a critical role in cell death. Here we found that RIPK1 and p21 may participate in the resistance to pirarubicin. In this study, we first found that inhibition of RIPK1 significantly decreased pAKT and increased p21, accompanied by G0/G1 phase cell cycle arrest and cell anti-proliferation in pirarubicin-treated hepatocellular carcinoma cells. Moreover, phosphorylation of AKT reversed the anti-proliferative effect of RIPK1 inhibitor in HCC, which proved that RIPK1-AKT-P21-dependent pathway played a key role in pirarubicin resistance. Using a mouse xenograft model, we further found that RIPK1 inhibitor combined with pirarubicin exerted synergistic anti-tumor effect in vivo. Upon exposure to pirarubicin treatment, xenografts under RIPK1 inhibition maintained higher levels of p21 than control xenografts. In conclusion, the results in our study demonstrated that RIPK1 inhibition enhances the anti-tumor effect of pirarubicin by overcoming drug resistance. RIPK1 inhibitor might be used as an adjuvant to potentiate the inhibitory effect of pirarubicin against primary hepatocellular carcinoma.

Oncol Rep 2016; 36:315-23.

Abstract
Bone marrow (BM) suppression (also known as myelosuppression) is the most common and most severe side-effect of therarubicin (THP) and thereby limits the clinical application of this anticancer agent. Lentinan (LNT), a glucan extracted from dried shiitake mushrooms (Lentinula edodes), exhibits a variety of pharmacological activities. The objectives of the present study were to determine the effect of LNT on the myelosuppression of THP-treated mice and to examine the pharmacological mechanism of these effects. In vivo experiments indicated that non-cytotoxic levels of LNT strongly increased blood myeloperoxidase (MPO) activity; improved BM structural injuries; increased the numbers of leukocytes and neutrophils in the blood and BM; elevated the blood levels of granulocyte colony-stimulating factor (G-CSF), granulocyte-macrophage colony-stimulating factor (GM-CSF) and macrophage colony-stimulating factor (M-CSF); and reduced the self-healing period in THP-treated mice. In vitro experiments indicated that LNT increased the viability of BM-derived macrophages (BMDMs) in a time- and dose-dependent manner without toxic side-effects and markedly increased the release of G-CSF, GM-CSF and M-CSF by BMDMs. Further analyses revealed that LNT activated the NF-κB and MAPK signalling pathways and promoted the nuclear import of p65 and that BAY 11-7082 (a specific inhibitor of NF-κB) suppressed the release of G-CSF, GM-CSF and M-CSF. Furthermore, we found that U0126, SB203580 and SP600125 (specific inhibitors of ERK, p38 and JNK, respectively) markedly inhibited the IKK/IκB/NF-κB-dependent release of G-CSF, GM-CSF and M-CSF. In conclusion, LNT induces the production of G-CSF, GM-CSF and M-CSF by activating the MAPK/NF-κB signalling pathway in BM cells, thereby mitigating THP-induced myelosuppression.

Abstract
Malignancy with liver metastasis plays an important role in daily oncology practice, especially for primary cancers of the gastrointestinal tract and hepatopancreatobiliary system. On account of the dual vascular supply system and the fact that most metastatic liver tumors are supplied by the hepatic artery, hepatic artery infusion chemotherapy (HAIC) is an appealing method for the treatment of liver metastases. Herein, we summarize recent study results reported in the literature regarding the use of HAIC for metastatic liver tumors, with special focus on colorectal cancer.

Abstract
Hepatic arterial infusion (HAI) selectively achieves high drug exposure of liver metastases from colorectal cancer. Such pharmacologic advantage has doubled the response rate of liver metastases on fluoropyrimidines (FP) delivered as HAI rather than intravenously, in a meta-analysis of randomised clinical trials (RCT). However, the improvement in antitumour efficacy did not consistently translate into any significant survival advantage across all randomised studies. However, the results of this meta-analysis should be cautiously interpreted due to the heterogeneity of the studies, inadequate study designs, obsolete therapy and high rate of early treatment discontinuation due to HAI technical failures or hepato-biliary toxicity. Most studies actually were performed before year 2000 and did not integrate the considerable progresses accomplished in the management of CRC, such as multidrug regimens instead of single agent FP and secondary resection of metastases, a major contributing factor for prolonged survival. Furthermore, the systemic exposure of patients given HAI was low without concomitant IV therapy, facilitating extra-hepatic relapses. The role of HAI in liver metastases from CRC should, therefore, be revisited, using modern multidisciplinary therapeutic approaches and appropriate study designs. Recommendations for the design of future RCTs exploring HAI are provided.

Abstract
AIM OF THE STUDY To improve prophylactic local treatment of hepatic metastasis from colonic cancer cells in the rat. METHODS The in vitro anticancer activity of 30 mn exposure to different drugs was first evaluated by dimethyl-thiazol-diphenyl-tetrazolium-bromide assay on confluent DHD/K12/PROb rat and HT29 human colonic cancer cells. Hepatic metastasis was induced by portal vein infusion of 12 x 106 PROb colonic cancer cells in syngenic BDIX rats. Hepatic and general tolerance to epirubicin was studied. Rats were treated with epirubicin delivered by either intravenous (IV), intraperitoneal (IP) or intraportal (Ipo) administration to compare their antitumoral effects. Hepatic distribution of epirubicin was assessed by fluorescence microscopy after IV, IP, Ipo, and combined administration. High pressure liquid chromatography was used to measure hepatic concentrations of epirubicin. RESULTS Only pirarubicin was fully cytotoxic in vitro against the two types of tumor cells. No general or hepatic toxicity was observed. The preventive effect on hepatic metastasis was similar for IV, IP, and Ipo pirarubicin treatments. Hepatic pirarubicin concentrations obtained by Ipo administration were 4.1-fold higher than those obtained after IV administration (P=0.013). Three hours after IP and Ipo administration, hepatic remnants of pirarubicin were similar and significantly higher that those obtained after IV administration (P=0.074). Clamping the hepatic vein doubled hepatic pirarubicin concentrations after Ipo administration (P=0.048). Combined hepatic and intraportal administration was necessary to achieve diffuse, intense and homogeneous fluorescence throughout the entire liver. CONCLUSION Homogeneous hepatic diffusion of pirarubicin was successfully achieved with combined hepatic vein and intraportal administration but systemic, intraperitoneal or intraportal administration had no preventive effect on hepatic metastasis. Other drugs could be tested using this approach to evaluate their efficacy and toxicity.

Abstract
Although chemoembolization is known to be an effective palliative treatment in hepatocellular carcinoma, it has a limited effect in large tumors. We report the case of a patient with a large hepatocellular carcinoma of the left liver who had a significant and sustained clinical response after six sessions of chemoembolization with a pirarubicin/amiodarone/lipiodol emulsion. Pirarubicin is an anthracycline which penetrates faster than doxorubicin into cancer cells. Amiodarone is a multidrug resistance inhibitor. Polysorbate 80, an excipient of injectable amiodarone stabilizes the anthracycline/lipiodol emulsion. The clinical efficacy of this new formulation could be evaluated in a phase II clinical trial.

Abstract
The aim of this study was to compare intra-arterial hepatic administration (IAH) versus i.v. administration of oxaliplatin and cisplatin in a VX2 tumor model in rabbits. VX2 tumors were implanted in the livers of White New Zealand female rabbits and 2 weeks later they received either cisplatin (4 mg/kg) or oxaliplatin (6 mg/kg) administered by IAH or i.v. Platinum pharmacokinetic parameters were measured by atomic absorption spectrometry at baseline, 2, 5 10, 20, 40 and 60 min, and then at 2, 4, 6 and 24 h after drug administration. Animals were sacrificed 24 h after drug administration to measure platinum concentrations in various tissues. After IAH oxaliplatin administration, we observed a significant decrease for total and filterable platinum in the Cmax compared with i.v. administration (12.4 versus 18.2 microg/l; p=0.02 and 11.2 versus 17.3 microg/l; p=0.02, respectively). Significant differences in various tissue concentrations were reported when comparing IAH and i.v. administration of oxaliplatin with IAH administration offering an advantage over i.v. administration. No differences in pharmacokinetic parameters or platinum tissue accumulation were apparent between the IAH and i.v. administration with cisplatin. We conclude that there is a significant pharmacokinetic advantage to using oxaliplatin for locoregional IAH chemotherapy compared with i.v. administration.

Abstract
BACKGROUND The purpose of this study was to evaluate the tolerance and efficacy of combining i.v. irinotecan, 5-fluorouracil (5-FU) and leucovorin (LV) with hepatic arterial infusion (HAI) of pirarubicin in non-resectable liver metastases from colorectal cancer. PATIENTS AND METHODS Thirty-one patients were included in a phase II trial with i.v. irinotecan/5-FU/LV administered every 2 weeks, combined with HAI pirarubicin 60 mg/m(2) on day 1 every 4 weeks. In most cases HAI was administered via a percutaneous catheter. RESULTS The main grade 3/4 toxicity was neutropenia, encountered in 78% of the patients. When all patients were considered in the analysis, tumour response rate was 15 out of 31 [48%; 95% confidence interval (CI) 32% to 65%]. Liver resection was made possible in 11 patients (35%; 95% CI 21% to 53%). There were no toxic death. Median overall survival was 20.5 months, and median progression-free survival was 9.1 months. In patients with completely resected metastases, median overall survival was not reached and median progression-free survival was 20.2 months. CONCLUSION The multimodality approach used in the present study was well-tolerated and yielded dramatic responses. An aggressive approach combining i.v. and HAI chemotherapy deserves further investigation.

Abstract
BACKGROUND A prospective phase II study was performed to determine the feasibility, efficacy and safety of arterial hepatic infusion (HAI) using pirarubicin combined with intravenous chemotherapy. PATIENTS AND METHODS From December 1991 to April 1994, 75 patients with unresectable colorectal metastases confined to the liver were included in this multicenter study to receive intra-arterial hepatic pirarubicin and a systemic monthly regimen of 5-fluorouracil (5-FU) and folinic acid. Sixty-four patients were analyzed in the intention-to-treat analysis and 61 in the per-protocol analysis. RESULTS Tolerance of this regimen was rather good; however, functional catheter problems were observed in 29 patients (45%) resulting in failure of HAI in 21 cases (33%) after a median of three cycles; vomiting grade 3 was present in 12.5% of patients, neutropenia grade 4 in 23% and alopecia grade 3 in 19%. The overall response rate was 31.9% in intention-to-treat analysis, and 39.3% in per-protocol analysis. Extrahepatic progression was reported in only 21.7% of patients. Time to hepatic progression and extra-hepatic progression was 8.3 and 15 months, respectively, in intention-to-treat analysis, and 11 and 18 months, respectively, in per-protocol analysis. Median survival was 19 and 20 months in intention-to-treat analysis and per-protocol, respectively. CONCLUSIONS In our study, the combination of intra-arterial pirarubicin and intravenous chemotherapy demonstrated some efficacy and good tolerance in the treatment of isolated colorectal liver metastases. This treatment seems to prevent extra-hepatic spread and prolong survival time. The results of this study have to be confirmed by new trials using more active systemic chemotherapy.

Abstract
There is no well-defined curative treatment for advanced and unresectable hepatocellular carcinoma. The widely used transarterial chemoembolization (TACE) with a doxorubicin-Lipiodol emulsion has not been shown to improve survival in randomized studies. Further, obstruction of the hepatic artery used in the procedure is badly tolerated in patients with cirrhosis. Drugs with a more rapid penetration into the cancer cells are likely to eliminate the need for obstruction of the hepatic artery. We therefore compared the cytotoxicity of another anthracycline pirarubicin with that of the commonly used doxorubicin. In this report, we show that pirarubicin has a greater in vitro cytotoxic effect than doxorubicin on the HepG2 and Hu-H7 human hepatoma cell lines. Pirarubicin emulsion with Lipiodol is more stable at 37 degrees C than doxorubicin-Lipiodol. Moreover, pirarubicin accumulates at a greater extent in the oil phase, permitting Lipiodol to act as a slow-releasing vector for the anthracycline. Further, amiodarone, a multidrug resistance inhibitor, was shown to decrease the intrinsic resistance of HepG2 and Hu-H7 cells to both anthracyclines, and the presence of polysorbate 80 in the amiodarone preparation increased the stability of the anthracycline-Lipiodol emulsions. We therefore conclude that pirarubicin is a better candidate for TACE than doxorubicin. The rapid and increased cytotoxicity of pirarubicin on hepatoma cancer cells and the stability of the pirarubicin-Lipiodol amiodarone emulsion could avoid the complete obstruction of the hepatic artery by Gelfoam sponges, and provide a better tolerated method of TACE in patients with latent liver insufficiency.
