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.展开更多

Methods Chemotherapy of 42 patients were randomly divided into group A (n = 20) with continuously constant arterial infusion, and group B (n = 22) with arterial chrono-modulated infusion. And the toxic effects and efficacy of two groups were compared. Results A significant difference was found in the toxic effects of digestive system between the two groups. The treatment response was similar in the two groups. Conclusions Intra-arterial chrono-chemotherapy may decrease the toxic effects and improve the life quality of these patients.

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.展开更多
