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.
