Lenvatinib combined with sintilimab plus transarterial chemoembolization as first-line treatment for advanced hepatocellular carcinoma

BACKGROUND Recently,combination therapy has shown a better trend towards improved tumour response and survival outcomes than monotherapy in patients with hepatocellular carcinoma(HCC).However,research on triple therapy[lenvatinib+sintilimab+transarterial chemoembolization(TACE)]as a first-line treatment for advanced HCC is limited.AIM To evaluate the safety and efficacy of triple therapy as a first-line treatment for advanced HCC.METHODS HCC patients with Barcelona Clinic Liver Cancer stage C treated with triple therapy were enrolled.All patients were treated with lenvatinib every day and sintilimab once every 3 wk.Moreover,TACE was performed every 4-6 wk if necessary.The primary outcome of the study was overall survival(OS).The secondary outcomes were the objective response rate(ORR),disease control rate(DCR),and incidence of adverse events.RESULTS Forty HCC patients who underwent triple therapy were retrospectively analysed from January 2019 to January 2022.With a median follow-up of 8.5 months,the 3-,6-,and 12-mo OS rates were 100%,88.5%,and 22.5%,respectively.The ORR and DCR were 45%and 90%,respectively.The median progressive free survival and median OS were not reached.Common complications were observed in 76%of the patients(grade 3,15%;grade 4,2.5%).CONCLUSION Combination therapy comprising lenvatinib,sintilimab and TACE achieved promising outcomes in advanced HCC patients and had manageable effects.

Conversion therapy for unresectable hepatocellular carcinoma:Advances and challenges

Recently,the World Journal of Gastrointestinal Oncology published an article entitled“Pathologically successful conversion hepatectomy for advanced giant hepatocellular carcinoma after multidisciplinary therapy:A case report and review of the literature”,in which the authors shared their successful experience with complete surgical resection after multidisciplinary conversion therapy.The study by Chu et al demonstrates the great challenges that the advanced hepatocellular carcinoma(HCC)poses to surgical oncology,reveals the complexity of conversion therapy for unresectable HCC,emphasizes the important role of a multidisciplinary management model in conversion therapy,and enriches our understanding of the dynamics of personalized treatment for different patients.At present,conversion therapy is a hot research topic in the treatment of unresectable HCC,which has brought new hope to many patients with moderately advanced HCC.However,there are still many urgent problems to be solved in conversion therapy.Here,we would like to further discuss the advances and challenges of conversion therapy for unresectable HCC with the authors and the general readers.

Advances in Research of Post Embolism Syndrome after Transarterial Chemoembolization(TACE)for Hepatocellular Carcinoma

This article reviews the concept and clinical manifestations of post embolism syndrome after transarterial chemoembolization(TACE),and the prevention or timely intervention of post embolism syndrome in advance is expected to reduce its incidence and degree in clinical treatment,and to improve the quality of treatment of Hepatocellular Carcinoma Carcinoma(HCC).

Nanomedicine-boosting icaritin-based immunotherapy of advanced hepatocellular carcinoma

Traditional treatments for advanced hepatocellular carcinoma(HCC),such as surgical resection,transplantation,radiofrequency ablation,and chemotherapy are unsatisfactory,and therefore the exploration of powerful therapeutic strategies is urgently needed.Immunotherapy has emerged as a promising strategy for advanced HCC treatment due to its minimal side effects and long-lasting therapeutic memory effects.Recent studies have demonstrated that icaritin could serve as an immunomodulator for effective immunotherapy of advanced HCC.Encouragingly,in 2022,icaritin soft capsules were approved by the National Medical Products Administration(NMPA)of China for the immunotherapy of advanced HCC.However,the therapeutic efficacy of icaritin in clinical practice is impaired by its poor bioavailability and unfavorable in vivo delivery efficiency.Recently,functionalized drug delivery systems including stimuli-responsive nanocarriers,cell membrane-coated nanocarriers,and living cell-nanocarrier systems have been designed to overcome the shortcomings of drugs,including the low bioavailability and limited delivery efficiency as well as side effects.Taken together,the development of icaritin-based nanomedicines is expected to further improve the immunotherapy of advanced HCC.Herein,we compared the different preparation methods for icaritin,interpreted the HCC immune microenvironment and the mechanisms underlying icaritin for treatment of advanced HCC,and discussed both the design of icaritin-based nanomedicines with high icaritin loading and the latest progress in icaritinbased nanomedicines for advanced HCC immunotherapy.Finally,the prospects to promote further clinical translation of icaritin-based nanomedicines for the immunotherapy of advanced HCC were proposed.

Degradation of FAK-targeting by proteolytic targeting chimera technology to inhibit the metastasis of hepatocellular carcinoma

Liver cancer is a prevalent malignant cancer,ranking third in terms of mortality rate.Metastasis and recurrence primarily contribute to the high mortality rate of liver cancer.Hepatocellular carcinoma(HCC)has low expression of focal adhesion kinase(FAK),which increases the risk of metastasis and recurrence.Nevertheless,the efficacy of FAK phosphorylation inhibitors is currently limited.Thus,investigating the mechanisms by which FAK affects HCC metastasis to develop targeted therapies for FAK may present a novel strategy to inhibit HCC metastasis.This study examined the correlation between FAK expression and the prognosis of HCC.Additionally,we explored the impact of FAK degradation on HCC metastasis through wound healing experiments,transwell invasion experiments,and a xenograft tumor model.The expression of proteins related to epithelial-mesenchymal transition(EMT)was measured to elucidate the underlying mechanisms.The results showed that FAK PROTAC can degrade FAK,inhibit the migration and invasion of HCC cells in vitro,and notably decrease the lung metastasis of HCC in vivo.Increased expression of E-cadherin and decreased expression of vimentin indicated that EMT was inhibited.Consequently,degradation of FAK through FAK PROTAC effectively suppressed liver cancer metastasis,holding significant clinical implications for treating liver cancer and developing innovative anti-neoplastic drugs.

TROVE2 regulated invasion and migration of hepatocellular carcinoma cells via heparanase

Background:The role of TROVE domain family member 2(TROVE2)has been well-demonstrated in autoimmune diseases;however,its involvement in liver cancer remains unclear.Therefore,this study aimed to explore the biological function and clinical significance of TROVE2 in hepatocellular carcinoma(HCC).Methods:The expression level of TROVE2 was analyzed in HCC and paired adjacent tissue samples using real-time reverse transcription-quantitative polymerase chain reaction.The impact of TROVE2 on migration and invasion in HCC cells was analyzed through Transwell assays and Western blotting.High-throughput transcriptome sequencing and bioinformatics analyses were performed to identify downstream target genes.Back-complementation experiments were employed to verify the influence of downstream proteins on TROVE2-induced invasion and migration of HCC cells.Results:TROVE2 exhibited significant overexpression in liver cancer tissue,correlating with shorter overall survival.Overexpression of TROVE2 facilitated the invasion,metastasis,and epithelial-mesenchymal transition(EMT)process of HCC cells,whereas TROVE2 knockdown restrained migration,invasion,and EMT in these cells.Transcriptome sequencing and bioinformatics analysis identified heparanase(HPSE)as a downstreamtarget protein of TROVE2.Subsequent back-complementation experiments provided evidence that HPSE overexpression promoted TROVE2-mediated prometastasis effects.Moreover,the study revealed that TROVE2 was capable of regulating the EMT pathway through GSK-3βphosphorylation.Conclusions:TROVE2 facilitated the invasion,migration,and EMT process ofHCC cells through phosphorylation of the HPSE/GSK-3βaxis,indicating its significance as an important protein in tumor progression.

Hemoperitonium: Atypical Presentation Caused by Spontaneous Rupture of Hepatocellular Carcinoma in an Undiagnosed Patient

Introduction: Acute hemoperitoneum due to the spontaneous rupture of hepatocellular carcinoma (HCC) is a rare case of non-traumatic intra-abdomen bleeding that requires a high index of suspicion to approach, especially if no known history of HCC. It can mislead the physicians when the patient presents in an atypical way. Case Presentation: In this case report, we describe a fortuitous rupture of hepatocellular carcinoma in a 58-year-old male who was not previously diagnosed as having HCC and who came with atypical symptoms and signs of hemoperitoneum. He was then treated by trans-arterial embolectomy. Discussion: Diagnosis of hemoperitoneum in a case with bradycardia and hypotension is uncommon, as it goes more towards cardiogenic shock than hypovolemic shock, especially in a patient who is previously not symptomatic and has no risk factor for hepatocellular carcinoma. Conclusion: physicians should be alert to the possibility of encountering a hemorrhagic shock, although no trauma injury in any hypotensive patient with no clear reason for his condition.

Research Progress of circRNAs during Epithelial- Mesenchymal Transition of Hepatocellular Carcinoma

Hepatocellular carcinoma is prone to invasion and metastasis.It often receives a low diagnosis rate in the early stage but has an extremely high mortality rate.Epithelial-mesenchymal transformation(EMT)is a key factor in promoting tumor cell invasion and metastasis.Circular RNA(circRNA)is involved in regulating EMT in hepatocarcinoma cells through multiple pathways,thereby affecting the occurrence and progression of hepatocellular carcinoma.This article mainly reviews the research progress of circRNA related to EMT core transcription factors,circRNA that promotes EMT in liver cancer,and circRNA that inhibits EMT in liver cancer.

challenges of advanced hepatocellular carcinoma

Hepatocellular carcinoma(HCC) is an aggressive malignancy,resulting as the third cause of death by cancer each year. The management of patients with HCC is complex,as both the tumour stage and any underlying liver disease must be considered conjointly. Although surveillance by imaging,clinical and biochemical parameters is routinely performed,a lot of patients suffering from cirrhosis have an advanced stage HCC at the first diagnosis. Advanced stage HCC includes heterogeneous groups of patients with different clinical condition and radiological features and sorafenib is the only approved treatment according to Barcelona Clinic Liver Cancer. Since the introduction of sorafenib in clinical practice,several phase Ⅲ clinical trials have failed to demonstrate any superiority over sorafenib in the frontline setting. Locoregional therapies have also been tested as first line treatment,but their role in advanced HCC is still matter of debate. No single agent or combination therapies have been shown to impact outcomes after sorafenib failure. Therefore this review will focus on the range of experimental therapeutics for patients with advanced HCC and highlights the successes and failures of these treatments as well as areas for future development. Specifics such as dose limiting toxicity and safety profile in patients with liver dysfunction related to the underlying chronic liver disease should be considered when developing therapies in HCC. Finally,robust validated and reproducible surrogate end-points as well as predictive biomarkers should be defined in future randomized trials.

Hepatic artery infusion chemotherapy for advanced hepatocellular carcinoma

Hepatocellular carcinoma(HCC) is one of the most common cancers worldwide. Surgery, percutaneous ablation and liver transplantation are the only curative treatment modalities for HCC. However, the majority of patients have unresectable disease at diagnosis. Therefore, effective treatment options for patients with advanced HCC are required. In advanced HCC, according to current international guidelines, sorafenib, a molecular targeted agent, is the standard treatment. However, alternative treatment modalities are required because of the low response rates and unsuitability of molecular agents in real practice. In various treatment modalities, mostly in Asia, hepatic arterial infusion chemotherapy(HAIC) has been applied to advanced HCC with a view to increasing the therapeutic efficacy. HAIC provides direct drug delivery into the tumor feeding vessels and also minimizes systemic toxicities through a greater first-pass effect in the liver. However, the sample sizes of studies on HAIC have been small and large randomized trials are still lacking. In this article, we describe the treatment efficacy of HAIC for advanced stage HCC and discuss future therapeutic possibilities.

Sorafenib in treatment of patients with advanced hepatocellular carcinoma:a systematic review

BACKGROUND: Sorafenib has become the standard first-line treatment for patients with advanced hepatocellular carcinoma (HCC). This study aimed to assess the efficacy and safety of sorafenib in advanced HCC patients and explore its true value for specific subgroups. DATA SOURCES: A computer-based systematic search from January 2005 to June 2011 with 'sorafenib' and 'advanced hepatocellular carcinoma' as search terms was performed for possible clinical trials. Hazard ratios (HR) and their 95% confidence intervals (CI) for overall survival (OS) and time to progression (TTP), rates of partial response (PR), rates of toxicity effects, and details of subgroup analysis were extracted. Meta-analyses were done using the software Review Manager (version 5.0). RESULTS: Six trials with 1164 patients were included. Based on three randomized controlled trials, the pooled HR (sorafenib/ placebo) was 0.66 for OS (95% CI: 0.56-0.78; P<0.00001) and 0.57 for TTP (95% CI: 0.47-0.68; P<0.00001). The pooled odds ratio (OR) for PR was 2.96 (95% CI: 0.96-9.15; P=0.06). For three single-arm trials, the pooled HR was 0.69 for OS (95% CI: 0.56-0.84; P=0.0002) and 0.64 for TTP (95% CI: 0.52-0.78; P<0.00001). The pooled OR for PR in three single-arm trials was 3.56 (95% CI: 1.22-10.39; P=0.02). Subgroup analysis indicated that sorafenib was less effective in patients with extrahepatic spread (with: P=0.13 vs without: P<0.0001), with normal alpha-fetoprotein level (AFP) (P=0.15 vs elevated: P=0.0006), and with elevated level of serum bilirubin (P=0.06 vs normal: P=0.0009). Sorafenib-based therapy significantly increased the risk of grade 3/4 hand-foot skin reaction, diarrhea, fatigue, and rash/desquamation.CONCLUSIONS: Sorafenib-based therapy benefits advanced HCC patients. Meanwhile, sorafenib is less effective for patients with extrahepatic spread, with normal AFP level and with elevated level of bilirubin.

Evolution of systemic therapy of advanced hepatocellular carcinoma

Hepatocellular carcinoma (HCC) commonly occurs in hepatitis B endemic areas, especially in Asian countries. HCC is highly refractory to cytotoxic chemotherapy. This resistance is partly related to its tumor biology, pharmacokinetic properties, and both intrinsic and acquired drug resistance. There is no convincing evidence thus far that systemic chemotherapy improves overall survival in advanced HCC patients. Other systemic approaches, such as hormonal therapy and immunotherapy, have also disappointing results. Recently, encouraging results have been shown in using sorafenib in the treatment of advanced HCC patients. In this review, we concisely summarize the evolution of developments in the systemic therapy of advanced HCC.

Advanced hepatocellular carcinoma and sorafenib: Diagnosis, indications, clinical and radiological follow-up

Advanced stage hepatocellular carcinoma(HCC) is a category of disease defined by radiological, clinical and hepatic function parameters, comprehending a wide range of patients with different general conditions. The main therapeutic option is represented by sorafenibtreatment, a multi-kinase inhibitor with anti-proliferative and anti-angiogenic effect. Trans-arterial Radio Embolization also represents a promising new approach to intermediate/advanced HCC. Post-marketing clinical studies showed that only a portion of patients actually benefits from sorafenib treatment, and an even smaller percentage of patients treated shows partial/complete response on follow-up examinations, up against relevant costs and an incidence of drug related adverse effects. Although the treatment with sorafenib has shown a significant increase in mean overall survival in different studies, only a part of patients actually shows real benefits, while the incidence of drug related significant adverse effects and the economic costs are relatively high. Moreover, only a small percentage of patients also shows a response in terms of lesion dimensions reduction. Being able to properly differentiate patients who are responding to the therapy from non-responders as early as possible is then still difficult and could be a pivotal challenge for the future; in fact it could spare several patients a therapy often difficult to bear, directing them to other second line treatments(many of which are at the moment still under investigation). For this reason, some supplemental criteria to be added to the standard modified Response Evaluation Criteria in Solid Tumors evaluation are being searched for. In particular, finding some parameters(cellular density, perfusion grade and enhancement rate) able to predict the sensitivity of the lesions to anti-angiogenic agents could help in stratifying patients in terms of treatment responsiveness before the beginning of the therapy itself, or in the first weeks of sorafenib treatment. This would bring a strongly desirable help in clinical managements of these patients.

Twenty-four hour intra-arterial infusion of 5-fluorouracil,cisplatin,and leucovorin is more effective than 6-hour infusion for advanced hepatocellular carcinoma

AIM. To evaluate the time dependence of intra-arterial 5-fluorouracil （5-FU） therapy for advanced hepatocellular carcinoma （aHCC）. METHODS： Thirty-seven adult Japanese patients who had aHCC and liver cirrhosis were treated with combined intra-arterial 5-FU, cisplatin （CDDP）, and leucovorin （LV）. The Japan Integrated Staging score （JIS score） of each patient was 3 or more. The patients were divided into two groups, alter which the 15 patients in group S were treated with 6-h infusion chemotherapy （LV at 12 mg/h, CDDP at 10 mg/h, and 5-FU at 250 mg/m^2 per 4 h） and the 22 patients in group L were treated with 24-h infusion chemotherapy （LV at 12 mg/h, CDDP at 10 mg/h, and 5-FU at 250 mg/m^2 per 22 h）. Continuous infusion chemotherapy was performed v/a the proper hepatic artery every 5 d for 4 wk using an implanted drug reservoir. RESULTS： The percentages of patients with a partial response after 4 wk of chemotherapy were 6.7% in group S and 31.8% in group L. The survival of group L was significantly better than that of group S, with the median survival time being 496 d in group L and 226 d in group S （P 〈 0.05）. CONCLUSION： Continuous 24-h intra-arterial infusion is more effective for aHCC and can markedly prolong survival time as compared to 6-h infusion.

Efficacy of hepatic arterial infusion chemotherapy in advanced hepatocellular carcinoma

AIM:To investigate the efficacy of hepatic arterial infusion chemotherapy(HAIC) using floxuridine(FUDR) in patients with advanced hepatocellular carcinoma(HCC) confined to the liver.METHODS:Thirty-four patients who had advanced HCC with unresectability or unsuccessful previous therapy in the absence of extrahepatic metastasis were treated with intra-arterial FUDR chemotherapy at ourhospital between March 2005 and May 2008.Among the 34 patients,9 patients were classified as Child class C,and 18 patients had portal vein tumor thrombus(PVTT).One course of chemotherapy consisted of continuous infusion of FUDR(0.3 mg/kg during day 1-14) and dexamethasone(10 mg on day 1,4,7 and 11),and this treatment was repeated every 28 d.RESULTS:Two patients(5.9%) displayed a complete response,and 12 patients(35.3%) had a partial response.The tumor control rate was 61.8%.The median overall survival times were 15.3 mo,12.4 mo and 4.3 mo for the patients who were classified as Child class A,Child class B and Child class C,respectively(P = 0.0392).The progression-free survival was 12.9 mo,7.7 mo and 2.6 mo for the patients who were classified as Child class A,Child class B and Child class C,respectively(P = 0.0443).The cumulative survival differed significantly according to the Child-Pugh classification and the presence of PVTT.In addition to hepatic reserve capacity and PVTT,the extent of HCC was an independent factor in determining a poor prognosis.The most common adverse reactions to HAIC were mucositis,diarrhea and peptic ulcer disease,but most of these complications were improved by medical treatment and/or a delay of HAIC.CONCLUSION:The present study demonstrates that intra-arterial FUDR chemotherapy is a safe and effective treatment for advanced HCC that is recalcitrant to other therapeutic modalities,even in patients with advanced cirrhosis.

Efficacy of 5-Fluorouracil and High-Concentration Cisplatin Suspended in Lipiodol by Short-Term Hepatic Arterial Infusion Chemotherapy for Advanced Hepatocellular Carcinoma with Portal Vein Tumor Thrombosis

Background: Since advanced hepatocellular carcinoma (HCC) is potentially fatal, and patients’ quality of life (QOL) often deteriorates during their treatment, improving the prognosis and QOL of patients given chemotherapy is very important. In addition, cost-effective treatments are highly desirable when chemotherapy must be given repeatedly. The aim of this study was to evaluate the efficacy and usefulness of 5-fluorouracil (5-FU) and high-concentration cisplatin by short-term hepatic arterial infusion chemotherapy (3-day FPL) in advanced HCC patients. Methods: Thirty patients with unresectable advanced HCC were enrolled. The patients underwent hepatic arterial infusion chemotherapy via the implanted port system with 5-FU on days 1 - 3 and a fine-powder formulation of cisplatin in suspended pre-warmed lipiodol on day 2 every 4 to 10 weeks. Tumor response was assessed one month later with CT. Results: All patients had evidence of portal vein invasion (Vp2-4). Four patients achieved a complete response (CR), 8 patients achieved a partial response (PR), and 7 patients had stable disease (SD). The median progression-free survival (PFS) and overall survival (OS) were 198 days and 452 days, respectively. The OS was significantly longer in the successful disease control group (CR, PR, and SD) than in the progressive disease group (P < 0.005). Conclusions: Three-day FPL was effective and tolerable in advanced HCC patients due to its shorter time of administration than conventional FP therapy. Therefore, repetitive 3-day FPL appears useful and contributes to improving the prognosis and QOL of patients with advanced HCC. In addition, this protocol is a cost-effective treatment.

Effects of an oral iron chelator, deferasirox, on advanced hepatocellular carcinoma

AIM To evaluate the inhibitory effects of deferasirox(DFX) against hepatocellular carcinoma(HCC) through basic and clinical studies.METHODS In the basic study, the effect of DFX was investigated in three hepatoma cell lines(Hep G2, Hep3 B, and Huh7), as well as in an N-nitrosodiethylamine-induced murine HCC model. In the clinical study, six advanced HCC patients refractory to chemotherapy were enrolled. The initial dose of DFX was 10 mg/kg per day and was increased by 10 mg/kg per day every week, until the maximum dose of 30 mg/kg per day. The duration of a single course of DFX therapy was 28 consecutive days. In the event of dose-limiting toxicity(according to the Common Terminology Criteria for Adverse Events v.4.0), DFX dose was reduced.RESULTS Administration of DFX inhibited the proliferation of hepatoma cell lines and induced the activation of caspase-3 in a dose-dependent manner in vitro. In the murine model, DFX treatment significantly suppressed the development of liver tumors(P < 0.01), and significantly upregulated the mR NA expression levels of hepcidin(P < 0.05), transferrin receptor 1(P < 0.05), and hypoxia inducible factor-1α(P < 0.05) in both tumor and non-tumor tissues, compared with control mice. In the clinical study, anorexia and elevated serum creatinine were observed in four and all six patients, respectively. However, reduction in DFX dose led to decrease in serum creatinine levels in all patients. After the first course of DFX, one patient discontinued the therapy. We assessed the tumor response in the remaining five patients; one patient exhibited stable disease, while four patients exhibited progressive disease. The one-year survival rate of the six patients was 17%.CONCLUSION We demonstrated that DFX inhibited HCC in the basic study, but not in the clinical study due to dose-limiting toxicities.

Chemotherapy with enteric-coated tegafur/uracil for advanced hepatocellular carcinoma

Hepatocellular carcinoma (HCC) is one of the most common malignancies worldwide, including Japan. Although the development of imaging modalities has made the early diagnosis of HCC possible, surgically resectable cases are relatively uncommon because of hepatic function reserve and/or an advanced stage at presentation. Several modalities, such as transcatheter arterial chemoembolization, percutaneous ethanol injection, microwave coagulation therapy and radiofrequency ablation are reportedly useful in treating patients with non-resectable disease. However, unfortunately, many HCC patients have tumor recurrence. The overall prognosis of patients with HCC is very poor, and treatment of the advanced form is still problematic. In this article, we review the clinical efficacy and toxicity of enteric-coated tegafur/uracil in the treatment of patients with advanced non-resectable HCC.

Clinical study of FOLFOX4 regimen for patients of advanced hepatocellular carcinoma

Objective:The aim of our study was to observe the efficiency and toxicity of oxaliplatin (L-OHP) combined with CF/5-FU in patients with advanced primary hepatocellular carcinoma.Methods:Twenty patients with advanced primary hepatocellular carcinoma had recurrence/metastasis after multiple courses of TACE (cisplatin and epirubicin,etc.).All patients were treated with FOLFOX4 regimen of the combination of oxaliplatin and leucovorin and 5-fluorouracil.Treatment was repeated every 2 weeks until disease progression or unacceptable adverse effects occurred.The efficiency was evaluated according to RECIST criteria,and toxicities according to American National Cancer Institute Common Toxicity Criteria (NCI CTC),respectively.Results:Twenty patients were assessable for the objective efficiency and for toxicity.No patient achieved complete response (CR),4 patients were partial response (PR),8 patients were stable disease (SD),8 patients were disease progression (PD);Time to tumor progression (TTP) of the patients ranged from 1.5 to 4.8 months,median TTP was 2.2 months;Overall survival (OS) of the patients ranged from 3 to 10.2 months,median OS was 5 months.The 2 patients' serum AFP level decreasing.Sixteen patients relieved the symptoms obviously,stabilized or raised up Karnofsky Score.The toxicities were mainly grade I-II arrest of bone marrow (50%),mild neurotoxicity (30%) and mild reaction of gastrointestinal tract (40%).Conclusion:FOLFOX4 regimen is effective and safe for patients with advanced primary hepatocellular carcinoma.It can be worthy of further clinical investigation.

Combination of TACE and FOLFOX4 in the treatment of unresectable advanced hepatocellular carcinoma:a prospective cohort study

Objective The aim of the study was to assess the effectiveness and safety of a combined therapy with transcatheter arterial chemoembolization(TACE)and FOLFOX4,in patients with unresectable advanced hepatocellular carcinoma(HCC).Methods In this study,patients with advanced HCC,that received treatment between November 2015 and October 2017,were recruited.Among these,30 patients were treated with TACE only(TACE group);whereas 33 patients were treated with a combination of FOLFOX4 chemotherapy and TACE(combination group).Survival analyses,including overall survival(OS)and progression free survival(PFS)analysis,were performed for both groups.Following this,the responses of patients to treatment were evaluated every 3 months,and the toxic and adverse events were observed.Results The median follow-up time was 9.2 months(3-36 months).In the combination group,at 3 months,a disease control rate(DCR)of 60.6%,and a median OS of 9.1 months was obtained[95%confidence interval(CI)6.5-11.7].In the TACE group,the DCR and OS were 33.3%and 5.5 months(95%CI 4.3-6.7),respectively.On the other hand,the PFS in the combination and TACE groups were observed as 5.6 months(95%CI 3.6-7.6)and 2.6 months(95%CI 2.0-3.2),respectively.Both these findings indicate a statistically significant difference(P=0.01)between both the groups.Similar TACE associated adverse events were observed in both groups.In the combination group,frequently observed FOLFOX4 related adverse effects included nausea(90.9%),leukopenia(75.8%),thrombocytopenia(69.7%),and vomiting(69.7%).Most adverse reactions were between grades I-III and were alleviated after symptomatic treatments.Conclusion The combination of TACE with FOLFOX4 therapy has better effectivity and safety than TACE alone.
