RESUMO
Objective To explore the clinical effect of radio-frequency ablation in the treatment of advanced pancreatic cancer.Methods Retrospectively analyzed the clinical data of 28 cases of radio-frequency ablation in the treatment of advanced pancreatic cance between January 2008 and December 2012 in 304 hospital.And choosed made 140 cases patients who only underwent the conservative treatment as the control group at the same period.Then compared the data of two groups patients.Results The mean tumor diameter was (4.8 ± 1.6) cm.The average radio-frequency time was (17.7 ± 4.3) minutes.There was no patient occurred of pancreatic fistula or postoperative bleeding,and no patient dead.Peri-operation pain relief rate was 88.9％.Twenty-three patients were followed up,and the follow up rate was 82.1％.The patients' survival rate who underwent radio-frequency ablation of 1 month,6 months and 1 year were 95.7％,65.2％ and 38.2％.The average survival time was (14.6 ± 2.2) months.And the data was significantly higher than that of the control group patients (97.4％,45.3％,19.1％,P =0.0306).Conclusions The radio-frequency ablation was one of an effective treatment method for the advanced pancreatic cancer patients.It can prolong the survival time of pancreatic cancer patients and alleviate the patient's pain.
