Analysis of the efficacy of transcatheter arterial infusion chemotherapy in the treatment of pancreatic carcinoma

Objective:To evaluate the clinical efficacy of infusion of gemcitabine(GEM) and fluorouracil(5-FU)through the celiac artery and superior mesenteric artery in the treatment of pancreatic carcinoma(PC).Methods:We analyzed 20 patients diagnosed clinically or pathologically with PC,without metastases,who had an estimated survival duration of>3 months in our department from May 2009 to December 2014.Nine patients were treated directly without surgical resection of the tumor,while the other 11 patients were treated after surgery.In all patients,the femoral artery was punctured using the Seldinger technique,and a catheter was placed in the opening of the celiac artery or the superior mesenteric artery.We administered 500 mg/m2 GEM and 500 mg/m2 5-FU.Observational data included data on clinical efficacy and survival rates during the follow-up period of 3-72 months.Results:Twenty patients were treated 85 times with transcatheter arterial infusion chemotherapy(TAI).The survival rates were 80%,40%,35%,20%,10%,and 5% at 3,6,12,24,and 72 months,respectively.Conclusion: TAI chemotherapy with GEM and 5-FU may be a therapeutic option for the treatment of PC.

Transcatheter arterial infusion for advanced hepatocellular carcinoma: Who are candidates?

AIM: To elucidate anticancer effects of transcatheter arterial infusion chemotherapy(TAI) in patients with hepatocellular carcinoma(HCC). METHODS: Data from a total of 95 patients with HCC who received TAI were analyzed retrospectively. The efficacy of TAI was evaluated according to the Response Evaluation Criteria in Cancer of the Liver. Overall survival was calculated from the date of initial treatment to the date of death or last follow-up. Survival curves were calculated by the Kaplan-Meier method, and differences in survival were evaluated by the log rank test. Clinical variables that were identified as statistically different by a univariate analysis were included into the Cox proportional hazard regression model for multivariate analysis. A prognostic index based on the regression coefficients derived from variables identified by the multivariate analysis was constructed. Stratification of the patients was conducted using this prognostic index. RESULTS: The patient group was comprised of 76 men and 19 women with an average age of 68 years(range: 37-82 years). Six patients(6.3%) showedcomplete response and 18 patients(18.9%) showed partial response, for an overall response rate of 25.2%. The median overall survival was 27.6 mo, and the proportions of survivors at 1, 2, and 5 years were 67.4%, 54.0%, and 17.4%, respectively. Multivariate analysis demonstrated that no prior transcatheter arterial chemoembolization, lactate dehydrogenase < 230 IU/L, and performance status of 0 were the independent favorable prognostic factors. The development of a 0-3-point prognostic score index was based on the sum of these three prognostic factors. Subsequently, the patients were categorized into three groups: those with a good(prognostic index = 0-1; n = 54), intermediate(prognostic index = 2; n = 26), or poor(prognostic index = 3; n = 15) prognosis. The median survival times in these three groups were 41.0, 21.2, and 6.8 mo, respectively(P < 0.01). CONCLUSION: Our simple prognostic index may be helpful for management of patients in determining treatment strategies for advanced HCC in the era of molecularly targeted therapy.

Transcatheter arterial infusion chemotherapy and embolization for primary lacrimal sac squamous cell carcinoma: A case report

BACKGROUND Although tumors of the lacrimal sac are rare,they represent a potentially lifethreatening situation that can easily be overlooked since patients present with features consistent with chronic dacryocystitis.Lacrimal sac squamous cell carcinoma is the most common lacrimal sac malignancy,but no definitive treatment is currently available.CASE SUMMARY We describe a 34-year-old unmarried male who presented with a red and swollen right lower eyelid,which gradually developed into a mass of the lower eyelid that obstructed vision in his right eye.He was treated with transcatheter arterial infusion chemotherapy and interventional embolization based on the tumor characteristics,and we also administered intensity-modulated radiotherapy and targeted therapy after tumor shrinkage.The tumor treatment demonstrated good efficacy,and the patient’s condition was stable after 10 mo of follow-up.CONCLUSION To our knowledge,this is the first report of lacrimal sac squamous cell carcinoma treated with transcatheter arterial infusion chemotherapy and interventional embolization,which might expand clinical treatment options for lacrimal sac carcinoma.

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 TACEHAIC.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 intraarterially 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.

Study of hepatic arterial infusion of Endostar combined with TACE on advanced hepatocellular carcinoma

Objective:To study the efficacy and safety of hepatic arterial infusion of Endostatin(YH-16,Endostar),combined with transcatheter arterial chemoembolization(TACE) on advanced hepatocellular carcinoma.Methods:Thirty patients with advanced hepatocellular carcinoma were enrolled in the study.The patients received hepatic arterial infusion of Endostar combined with TACE.The efficacy was evaluated strictly after 1-2 cycles according to RECIST criteria and the value of AFP;quality of life(QOL) was evaluated according to Karnofsky scores.Adverse effects were evaluated too.Results:29 cases' efficacy was evaluated among the total 30 cases.The KPS were significantly increased after the treatment(80.39 ± 8.37 vs 73.93 ± 9.22,P = 0.002).Compared with control group,the objective response rate(CR and PR) and the rate of AFP negative changed were significantly higher(P = 0.021,P = 0.046).The adverse effects were not obvious.Conclusion:The QOL and preliminary efficiency of patients of advanced hepatocellular carcinoma may be improved by hepatic arterial infusion of Endostar combined with TACE,the rate of AFP negative changed were significantly higher too,and there are little of adverse effects.It is worthy to clinical generalization and further clinical observation.

The Role of Serum Cytokeratin 19 Fragment in Transarterial Infusion against Invasive Bladder Cancer

Background: We used transcatheter arterial infusion chemotherapy (TAI) for patients with T1G3 and greater than T2 bladder cancer, which was diagnosed after extensive and deep transurethral resection of bladder tumor (TUR-BT), and we investigated the utility of serum cytokeratin 19 fragment (CYFRA) as a predictive factor of the response to therapy. Material and Methods: From November 2001 to November 2010, 56 patients (46 males and 10 females) with pathologically confirmed T1 G3 or greater than T2 bladder cancer after TUR-BT underwent two courses of TAI of cisplatin, methotrexate and doxorubicin as neoadjuvant setting. Then, patients underwent evaluation TUR-BT. Thereafter, the bladder was preserved in patients with superficial or undetectable tumors on TUR-BT. Advanced cases and residual bladder tumor cases were treated with total cystectomy or systemic chemotherapy. CYFRA levels were measured before and after performing TAI. Results: With this therapy, the 5-year survival rate was 85.7% in pT1G3, 82.3% in pT2, and 66.6% in greater than pT3 cases. Bladder preservation with no recurrence was observed in 58.7% of the patients. Grade III adverse events included leucopenia (6/56 patients: 10.7%). Serum CYFRA levels significantly decreased with treatment (in 4/6 patients with elevated CYFRA levels). Conclusion: These results suggest that although total cystictomy is usually indicated for T1G3 bladder cancers, bladder preservation and control of micrometastases can be achieved by performing TAI after extensive and deep TUR-BT. Our results also suggest the utility of monitoring serum CYFRA to assess the response to therapy.

Efficacy of transcatheter arterial chemoembolization combined with ganfule on advanced hepatocellular carcinoma

Objective： The aim of this study was to evaluate the efficacy of transcatheter arterial chemoembolization （TACE） combined with a Chinese compound preparation of ganfule on advanced hepatocellular carcinoma （HCC）. Methods： The study population consisted of 132 advanced HCC patients with Child-pugh NB. Tumor in all patients was involved with main trunk of portal vein and/or inferior vena cava, or local lymph node metastasis, or distant metastasis. TACE combined with ganfule were performed in 65 patients with advanced HCC （interventional treatment group）, 67 patients were treated with traditional Chinese herbal drug alone （Chinese herb group）. The prime end point was overall survival （OS）, and prognostic factors were analyzed. Results： The median OS was 205 days [95% confidence interval （CI）, 155-255 days] in interventional treatment group and 127 days （95% CI, 70-184 days） in Chinese herb group （P 〈 0.05）. The 6-month, 1-year, and 2-year OS rates were 58.9%, 29.1%, 7.7% in interventional treatment group, and 33.3%, 12.3%, 1.8% in Chinese herb group, respectively. The portal vein thrombosis, ECOG performance status （PS） were independent prognostic factors for OS. Conclusion： Ttranscatheter arterial chemoembolization combined with a Chinese compound preparation of ganfule could greatly prolong the OS of advanced HCC patients. The portal vein thrombosis and ECOG PS were independent prognostic factors for OS.

Background:The aim of the study was to investigate the efficacy of continuous transcatheter arterial infusion chemotherapy combined with transarterial chemoembolization(TACE)for the treatment of advanced pancreatic cancer with liver metastasis.Methods:Sixty patients with advanced pancreatic cancer and liver metastases were enrolled in this study.In the treatment group,31patients underwent continuous transcatheter arterial infusion chemotherapy combined with TACE regional arterial thermal perfusion,whereas 29 patients included in the control group received intravenous chemotherapy with gemcitabine and S-1.All patients received maintenance chemotherapy with S-1 after 4 cycles of the study regimen.Treatment efficacy,quality of life,survival,and toxicity were evaluated.Results:Efficacy was better in the treatment group than in the control group,as reflected by the objective remission,partial remission,and disease progression rates(all P<0.05).The Eastern Cooperative Oncology Group and Numerical Rating Scale pain scores were also higher in the treatment group(both P<0.05).In survival analysis,the 1-year overall survival rates in the treatment and control groups were64.516%and 10.345%,respectively,whereas the median overall survival times were 16 and 6 months,respectively(both P<0.05).The6-month progression-free survival rates in the treatment and control groups were 77.419%and 13.790%,respectively,and the median progression-free survival times were 12 and 3 months,respectively(both P<0.05).The rates of hematological and nonhematological toxicological adverse effects were also lower in the treatment group(both P<0.05).Although the rate of liver dysfunction was higher in the treatment group,this finding had no adverse effects on prognosis.Conclusions:Continuous transcatheter arterial infusion chemotherapy combined with TACE regional arterial perfusion chemotherapy resulted in better efficacy and safety outcomes in patients with pancreatic cancer and liver metastasis,suggesting its utility as a reference method for the clinical treatment of advanced pancreatic cancer.

Neoadjuvant hepatic arterial infusion chemotherapy for resectable hepatocellular carcinomas

Aim: To evaluate the effect of neoadjuvant hepatic arterial infusion chemotherapy (HAIC) on the survival of patients with resectable hepatocellular carcinoma (HCC). Methods: Between January 2003 and January 2014, 80 patients underwent hepatic resection for HCC. Of these patients, we evaluated 49 patients who met the following inclusion criteria: (1) preserved liver function (Child-Pugh A);(2) resectable HCC (≤ 3 nodules, regardless of the size);and (3) HCC with high-grade malignant potential. Among them, 13 patients underwent neoadjuvant HAIC and curative hepatectomy (treatment group). The remaining 36 patients underwent curative hepatic resection without neoadjuvant therapy (control group). Survival after hepatic resection was compared retrospectively between the groups. Results: During follow-up, 2 (15.4%) patients in the treatment group and 25 (69.4%) patients in the control group developed recurrence. The 1-, 3-, and 5-year disease-free rates (100%, 78.6%, and 78.6%, respectivelyvs. 65.8%, 33.7%, and 26.6%, respectively;P = 0.003) and overall survival rates (100%, 100%, and 100%, respectively vs. 91.7%, 77.8%, and 55.3%, respectively;P = 0.037) were significantly better in the treatment group than in the control group. Conclusion: Neoadjuvant HAIC decreased the risk of recurrence and improved survival in patients with HCC with high malignant potential.

肝癌肝动脉化疗栓塞及肝动脉灌注化疗术后疼痛的治疗进展

肝动脉化疗栓塞(TACE)及肝动脉灌注化疗(HAIC)等转化治疗是目前将不可切除晚期肝癌降期转化为可切除肝癌的主要治疗方法,不仅可以有效提高患者生存率,同时可为患者提供肝移植的机会。然而,疼痛为肝癌TACE和HAIC治疗的主要并发症,TACE术后腹痛的发生率为19.3%~71.2%,HAIC治疗过程中近64.6%的患者会出现不同程度的疼痛,严重影响患者的生活质量,缩短患者的生存期。目前,TACE和HAIC引起疼痛的发生机制尚不明确,可能与栓塞剂阻塞肿瘤供血动脉后局部肝组织肿胀、肝组织被膜压力增高或肿块包膜被牵拉、栓塞剂与抗肿瘤药物对肝动脉的化学刺激、邻近正常脏器的误栓及肠管缺血所致的内脏痛觉敏化有关。疼痛的干预措施主要有两种,一种是利多卡因、阿片类药物、非甾体抗炎药物及糖皮质激素等干预措施;另一种是腕踝针、中药汤剂等其他干预措施,但治疗效果参差不齐。本文就肝癌TACE及HAIC治疗所致疼痛情况及治疗现状进行综述,以期为其临床治疗提供参考。

目的：探讨原发性肝癌切除术后行预防性经肝动脉化疗栓塞术（TACE）或化疗灌注术（TAI）的疗效比较。方法回顾性分析2011年6月-2012年6月行原发性肝癌切除术并在术后1-3个月行预防性介入治疗的79例患者，研究终点为2013年6月。病例分为TACE（n=41）和TAI（n=38）2组。2组患者术前年龄、性别、肝功能Child-Pugh评分、术前肿瘤直径及AFP水平差异均无统计学意义。介入术中将导管超选进入肝固有动脉，造影证实无新生肿瘤血管和肿瘤病灶后经导管注入药物，TACE组采用碘油化疗药物乳剂，TAI 组则采用单纯化疗药物灌注。采用卡方检验比较2组的1年复发率， Kaplan-Meier 估计法比较无瘤生存期，t检验比较平均住院日差别。结果79例患者中共有11例患者确认为切除术后复发，总体1年复发率为13．9%，其中TACE组1年复发率为12．2%（5/41），TAI组为15．8%（6/38），差异无统计学意义（χ^2=0．213，P=0．645）。 TACE组平均无瘤生存期为（21．6±1．5）个月，TAI组为（17．4±3．0）个月，TACE组明显优于TAI组（P =0．038）。 TACE组平均住院日为（6．3±1．8）d，TAI组为（5．9±2．1）d，两组差异无统计学意义（P=0．522）。结论原发性肝癌切除术后行预防性TACE或TAI的1年复发率无差别，但采用TACE可望提高患者术后的无瘤生存期。

胰腺癌肝转移的介入治疗

目的:评价经肝动脉化疗栓塞及胰腺动脉局部灌注化疗对胰腺癌肝转移的反应率、生存时间以及术后影响患者生存的主要因素。方法:2002年1月至201 1年6月对125例胰腺癌伴肝转移患者进行了265次介入治疗(所有患者均联合胰腺病灶放疗)。包括肝动脉化疗栓塞+胰腺动脉灌注化疗220例次,桡动脉留置导管持续胰腺动脉灌注化疗45例次。通过影像学资料观察肿瘤对介入治疗的反应,分析患者术后的生存时间,肿瘤无进展生存时间。调查患者临床特征、肿瘤大小和治疗等各种因素对患者生存的影响。结果:125例患者进行了265次介入治疗,对其中105例患者影像学资料进行分析,12例患者肿瘤对治疗有部分反应,17例患者对治疗有轻微反应,68例患者肿瘤无明显变化,8例患者肿瘤进展。平均生存时间和无进展生存时间分别为6.7个月和3.8个月。多因素回归分析显示:肿瘤>肝脏体积的75%和乳酸脱氢酶浓度影响术后患者的生存时间。若患者对介入反应良好,则生存时间也会相应延长。结论:介入治疗可以使胰腺癌肝转移患者肿瘤缩小,病情稳定。其中肿瘤大小、乳酸脱氢酶浓度和对肿瘤对治疗的反应性是影响患者生存率的主要因素。
