Efficacy of continuous arterial perfusion chemotherapy combined with transarterial chemoembolization regional arterial thermal perfusion in the treatment of pancreatic cancer with liver metastases

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.

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

AIM To determine the efficacy and safety of transarterial embolization and low-dose continuous hepatic arterial infusion chemotherapy with oxaliplatin and raltitrexed in hepatocellular carcinoma(HCC) with major portal vein tumor thrombus(MPVTT).METHODS eighty-six patients with MPVTT accepted routine embolization. The catheter was kept in the hepatic artery and oxaliplatin(50 mg in 250 m L of glucose) was infused by pump for 4 h,followed by raltitrexed(2 mg in 100 m L of 0.9% saline) infusion by pump for the next 1 h. The efficacy and safety were evaluated afterthe transarterial chemoembolization(TACe).RESULTS Full or partial embolization was achieved in 86 cases,where all the cases received low dose continuous hepatic arterial infusion chemotherapy. Complete responses(CRs),partial responses(PRs),stable disease(SD),and disease progression(PD) for intrahepatic disease were observed in 0,45,20,and 21 patients,respectively. The 1-,2-and 3-year overall survival rates of the 86 patients were 40.7%,22.1%,and 8.1% respectively,and the median survival time was 8.7 mo. Complication was limited. CONCLUSION TACE with low dose continuous hepatic arterial infusion of oxaliplatin and raltitrexed could be an option in MPVTT patient; it was shown to be effective in patients with advanced HCC with MPVTT with less toxicity.

Effect of neoadjuvant chemotherapy on locally advanced cervical cancer by internal iliac arterial infusion

Objective:To evaluate the effect of preoperative chemotherapy on locally advanced cervical cancer by internal iliac arterial infusion.Methods:Sixty two patients with bulky or locally advanced cervical cancer from 1999 to 2004 were underwent internal iliac arte- rial infusion chemotherapy by using Seldinger technique.Combined regimens were applied in- cluding cisplatin as the major drug.Two weeks later,all patients received radical hysterectomy. Results:The local tumor regression rate was 93.55%.Postoperative pathologic examination showed that no cervical tumor residue in stumps were found in 61 of 62 patients who underwent radical hysterectomy.Large quantity of necrotic tissue appeared on primary tumor.In 16 patients with positive lymph nodes,15 demonstrated necrotic lymph nodes.Conclusion:Internal iliac ar- terial infusion chemotherapy could effectively reduce tumor volume,increase surgical success rate and decrease lymph nodes and subclinical metastasis rates.

APOPTOSIS AND PROLIFERATION OF TUMOR CELLS IN LOCALLY ADVANCED CERVICAL CANCER AFTER NEOADJUVANT INTRAARTERIAL CHEMOTHERAPY

Objective: Through observing the clinical response toneoadjuvant intraarterial chemotherapy in locally advanced cervical cancer and investigating the changes of p53 proteinexpression, proliferation and apoptosis of tumor cells afterchemotherapy, to study the relationship between biological markers and chemotherapeutic response. Methods: 20women with locally advanced squamous cervical cancerreceived consecutive infusion chemotherapy of five days ofcisplatin and adriamycin via the superselective uterineartery. The response to chemotherapy was evaluated bygynecologic examination and ultrasonography 3 weeks after chemotherapy. The changes of apoptotic index (AI), proliferation index (PI) and p53 expression of tumor cellswere detected by immunohistochemical technique.Results: The clinical response rate of locally advancedsquamous cervical cancer to uterine artery infusionchemotherapy was 70%. No change of PI was found 3 weeks after treatment, but AI significantly increased from2.79?.76 to 4.29?.13 (P<0.01), and AI/PI from 5.68?.21 to 9.00?.95 (P<0.05). On the contrary, the expression of p53was significantly decreased (P<0.05). Patients whoresponded to chemotherapy showed higher PI before chemotherapy and significantly increased AI and AI/PIafter chemotherapy than non-responders (P<0.05).Conclusion: Higher PI was an indication for neoadjuvantintraarterial chemotherapy. One more cycle ofchemotherapy should be given to those who have significantly increased AI or AI/PI after chemotherapy, while definite treatment such as surgery or/and radiotherapy should be immediately given to those patients without increased AI or AI/PI.

Application of Regional Arterial Infusion Chemotherapy in Advanced Gastric Cancer

Gastric cancer ranks as the fifth most common malignant tumor worldwide and is the third most common cause of cancer-related death. For advanced gastric cancer (AGC), neoadjuvant chemotherapy (NAC) can reduce its stage, increase the rate of radical resection, improve response to treatment, reduce the risk of local recurrence and improve survival rate. Regional arterial infusion chemotherapy (RAIC) is a form of NAC that involves directly injecting chemotherapeutic drugs into the tumor site through the tumor-feeding artery. RAIC increases the local drug concentration around the tumor, thereby improving the therapeutic responses and reducing the adverse effects of the drugs. In recent years, RAIC has attracted increasing attention. This article summarizes the basic principles, procedure, chemotherapy regimens, adverse drug reactions and complications, clinical applications and response evaluation of RAIC in the treatment of AGC.

PREOPERATIVE CHEMOTHERAPY OF CONTINUOUS INFUSION OF 5-FLUOROURACIL, EPIRUBICIN OR PIRARUBICIN AND CYCLO- PHOSPHAMINE IN OPERABLE PRIMARY BREAST CANCER

Objective: To evaluate the feasibility and activity of continuous-infusion of fluorouracil in association with epirubicin or pirarubicin and cyclophosphamine as neoadjuvant regimen in patients with primary breast cancer. Methods: A total of 111 (including 114 breasts) were entered into the study. Chemotherapy consisted of two to six cycles of epirubicin 50 mg/(m2穌) and cyclophosphamide 500 mg/(m2穌) on day 1 and 8, and continuous intravenous administration of 5-fluorouracil 200 mg/(m2穌) from day 1 to 28 with a microinfusional elastomer (CEFci) or pirarubicin 35 mg/(m2穌) on day 1 and 8 instead of epirubicin (CTFci). Results: The overall response rate was 87.7%. Forty-five patients (39.5%) attained a complete clinical response and 27 (23.7%) attained a pathological complete response. CTFci regimen was superior to CEFci regimen in response rate,the pathological complete response rate (pCR) of former regimen was significantly higher than that of latter regimen (34.8% vs. 16.2%) (P=0.022). The pCR rate in ER/PgR negative tumor was significantly higher than that of ER/PgR positive tumor, achieving 33.3% and 7.5% respectively (P=0.001, x2=11.043). There was no relationship between HER-2 expression and tumor response. The toxicity of two regimens was well tolerated. Alopecia was mild in CTFci regimen comparing with CEFci regimen but neutropenia in CTFci regimen was higher than CEFci regimen. Conclusion: Continuous-infusion of fluorouracil in association with epirubicin or pirarubicin and cyclophosphamine is effective regimens as neoadjuvant chemotherapy for primary breast cancer and the toxicity is well tolerated. Pirarubicin regimen was superior to epirubicin regimen in response rate.

Effect of multiple-phase regional intra-arterial infusion chemotherapy on patients with resectable pancreatic head adenocarcinoma

Background Regional intra-arterial infusion chemotherapy （RIAC） has been more valuable to improve prognosis and quality of life of patients with inoperable pancreatic adenocarcinomas, and adjuvant RIAC plays an important role in prolonging survival and reducing risk of liver metastasis after radical resection of pancreatic cancer, but the effect of preoperative or multiple-phase RIAC （preoperative combined with postoperative RIAC） for resectable pancreatic cancers has not been investigated. In this prospective study, the effect of multiple-phase RIAC for patients with resectable pancreatic head adenocarcinoma was evaluated, and its safety and validity comparing with postoperative RIAC were also assessed. Methods Patients with resectable pancreatic head cancer were randomly assigned to two groups. Patients in group A （n=-50） were treated with new therapeutic mode of extended pancreaticoduodenectomy combined with multiple-phase RIAC, and those in group B （n=-50） were treated with extended pancreaticoduodenectomy combined with postoperative RIAC in the same period. The feasibility, compliance and efficiency of the new therapeutic mode were evaluated by tumor size, serum tumor markers, clinical benefit response （CBR）, surgical complications, mortality and toxicity of RIAC. The disease-free survival time, median survival time, incidence of liver metastasis, survival rate at 1, 2, 3 and 5 years were also observed. Life curves were generated by the Kaplan-Meier method. Results The pain relief rate and CBR in group A was 80% and 84% respectively. Serum tumor markers decreased obviously and tumors size decreased in 26% of patients after preoperative RIAC in group A. No more surgical complications, mortality or severe systemic side effects were observed in group A compared with group B. The incidence of liver metastasis in group A was 34% which was lower than 50% in group B. The disease-free survival time and median survival time in group A were 15.5 months and 18 months respectively. The 1-, 2-, 3- and 5-year survival rates were 54.87%, 34.94%, 24.51% and 12.25% respectively. There was no significant difference of survival time or survival rates between two groups. Conclusions Multiple-phase RIAC is effective in combined therapy of resectable pancreatic head carcinomas by enhancing inhibition of tumor growth and reduction of liver metastasis, without negative effect on patients＇ safety or surgical procedure.
