PERIPANCREATIC ARTERIAL LIGATION COMBINED WITH ARTERIAL INFUSION REGIONAL CHEMOTHERAPY FOR TREATING PATIENTS WITH ADVANCED PANCREATIC CARCINOMA

Objective To find out a new treatment method for advanced pancreatic carcinoma. Methods Twenty nine patients with advanced pancreatic carcinoma and liver metastases were randomly divided into 2 groups.Group A ( n =11) underwent bilio enterostomy and/or gastro enterostomy combined with systemic chemotherapy after operation;Group B( n =18) underwent bilio enterostomy and/or gastro enterostomy combined with peripancreatic arterial ligation and arterial infusion regional chemotherapy.The alleviation of clinical symptom,the change of carcinoma volume by BUS and CT scan,survival period and serum CEA were observed in two groups. Results The symptoms were alleviated apparently in most cases in Group B;BUS and CT scan showed that the tumor volume decreased apparently in Group B;The response rate was 67.7% in Group B,and 18.2% in Group A,respectively( P <0.01);the mean survival period was (4.8±0.6) months in Group A,and (12.5±1.2) months in Group B,respectively( P <0.01),there was significant difference between the two groups.The decrease of serum CEA was 54% in Group A and 60% in Group B,but the difference was not significant( P >0.05). Conclusion Peripancreatic arterial ligation combined with arterial infusion regional chmotherapy is believed to be effective against both pancreatic carcinoma and liver metastases,and it can alleviate the clinical symptoms,postpone the growth speed of tumor,and prolong the survival period.

Peripancreatic artery ligation and artery infusion chemotherapy for advanced pancreatic carcinoma

Objective To develop a new treatment for advanced pancreatic carcinoma. Methods Twenty-nine patients with advanced pancreatic carcinoma (12 patients with liver metastasis at the same time) were randomly divided into two groups. In group A (n=11), patients underwent bilio-enterostomy and/or gastro-enterostomy combined with systemic chemotherapy after surgery. In group B (n=18), patients underwent bilio-enterostomy and/or gastro-enterostomy combined with peripancreatic arterial ligation and arterial infusion regional chemotherapy. Twenty-four patients were followed up for 3-18 months. The palliation of clinical symptoms, changes in carcinoma size by B ultrasound (BUS) and CT scan, survival period and serum carcinoembryonic antigen (CEA) were observed and compared between the two groups. Results Symptoms were alleviated in most patients in group B, and BUS and CT scan showed that tumor volume decreased in group B. The response rate was 66.7% in group B and 18.2% in group A (P<0.01). The mean survival period was 4.8±0.6 months in group A and 12.5±1.2 months in group B (P<0.01); there were significant differences between the two groups. The decrease in serum CEA was 54% in group A and 60% in group B; the difference was not significant (P>0.05). Conclusion Peripancreatic arterial ligation combined with arterial infusion regional chemotherapy is effective against both pancreatic carcinoma and with liver metastases. It can alleviate clinical symptoms, postpone the growth rate of tumor and prolong the survival period.
