RESUMO
Objective To study the clinical efficacies of different surgical palliative treatments for patients with advanced pancreatic carcinoma.Methods A retrospective analysis was conducted on the clinical data of 119 patients with advanced pancreatic carcinoma who were treated in the department of General Surgery of Linyi's Central Hospital from January 2010 to January 2016.According to the different surgical methods the patients received,they were divided into the seed group (n =38),the radiofrequency ablation (RF) group (n =52) and the control group (n =29).Patients' general data,operation data,postoperative complications and follow-up profiles were analyzed.Results There was no significant difference in the patients'general data among the three groups of patients (P ＞ 0.05).The incidences of postoperative complication in the seed group,the RF group and the control group were 55.3％,38.5％ and 20.7％,respectively.There was significant differences between the incidences of postoperative complications between the seed group and the control group (P ＜ 0.05).There was no perioperative death.The postoperative follow-up rate was 91.6％.Pain in the seed group and the RF group significantly improved,while it was not significantly improved in the control group.There were significant differences in the postoperative pain scores (P ＜0.05).The 6 months,1-year and 2-year overall survival rates were 61.3％,25.9％,8.6％ respectively.The median survival was 8 months.In the seed group,the 6 months,1-year and 2-year survival rates were 75.2％,37.8％,18.9％ respectively.The median survival was 9 months.In the RF group,the 6 months,1-year and 2-year survival rates were 60.4％,25％,6.3％ respectively.The median survival was 8 months.In the control group,the 6 months,1-year and 2-year survival rates were 53.4％,15.3％,3.8％ respectively.The median survival was 6.5 months.On log-rank test,there was no significant difference in survival rates among the three groups (P =0.145).Conclusions Patients with advanced pancreatic carcinoma had poor prognosis.I125 radioactive particles implantation and radiofrequency ablation were useful to improve patients'quality of life and prolonged their survival.
RESUMO
Objective To evaluate the perioperative safety and effect of irreversible electroporation (IRE) in the treatment of locally advanced pancreatic carcinoma (LAPC).Methods Twenty patients with imaging and cytohystological diagnosis of unresectable locally advanced pancreatic carcinoma were enrolled to undergo IRE treatment.The perioperative IRE-related complications were primarily analyzed to evaluate the safety of the procedure.The tumor reduction and biological response were analyzed through CT/MRI imaging and serous level of CA19-9.Results All patients were successfully treated with an average tumor size of(4.2 ± 0.6) cm and an average procedure time of (52.0 ± 23.3) minutes.Three intraoperative procedure-related complications were observed (15.0％) including two transient hypertension and one transient superventricular tachycardia.Six postoperative complications were described including two Grade A pancreatic fistula,one infection of incision,one portal vein thrombosis,one gastrointestinal hemorrhage and two functional delayed gastric emptying.The symptom remission rate was 73.7％ and lower serum CA19-9 level was recorded in all patients at discharge.Conclusions IRE is a safe and feasible procedure in the treatment of LAPC, and a reasonable operation strategy of IRE is helpful to consolidate the safety and efficacy.
RESUMO
Objective To investigate curative effects of interventional therapy,palliative operation,and palliative operation combined with ~(125)I seed implantation for the treatment of advanced pancreatic carcinoma.Methods A total of 103 patients with unresectable pancreatic cancer were treated with percutaneous transhepatic cholangiography and drainage(Interventional Group,15 patients),or cholangiojejunostomy and gastroenterostomy(Palliative Group,60 patients),or palliative operation combined with ultrasound-guided ~(125)I seed interstitial implantation(Combination Group, 28 patients),respectively.Results Of 21 patients with preoperative pain in the Combination Group,the rate of partial pain relief and complete pain relief were 14.3%(3/21) and 76.2%(16/21),respectively,which were significantly higher than those in the other two groups(?~2=6.305,P=0.012;?~2=4.525,P=0.033).The median survival time was significantly longer in the Combination Group(8 months) than in the Palliative Group(7 months) and the Interventional Group(2 months)(P=0.0005).Conclusions Percutaneous transhepatic cholangiography and drainage can be applied to patients who cannot tolerate open surgery.Conventional palliative operations combined with ~(125)I seed implantation benefits the patients both in survival time and in pain relief.
