[Efficacy evaluation of high intensity focused ultrasound combined with intra-arterial infusion of gemcitabine in the treatment of pancreatic cancer].

OBJECTIVE

The aim of this study was to discuss the clinical effectiveness of high intensity focused ultrasound (HIFU) combined with gemcitabine administered by intra-arterial infusion on intermediate and advanced pancreatic cancer.

METHODS

Forty-eight patients with intermediate and advanced pancreatic cancer were divided into two groups. Twenty-four patients of the experimental group were treated by HIFU combined with gemcitabine, and 24 patients of the the HIFU group were treated by HIFU alone. Then the curative effect, extent of pain relief, and survival time were compared in the course of the treatment between the two groups.

RESULTS

As compared with those in the control group, the overall response rate, level of pain relief, and 12-month survival rate after therapy were higher and the median survival time was longer in the joint group (P < 0.05).

CONCLUSIONS

Ultrasound imaging, CT and associated tumor marker detection can make effective measurement to evaluate curative effect on pancreatic carcinoma. HIFU plus gemcitabine administered by intra-arterial infusion can improve the clinical therapeutic efficacy, pain relief, quality of life and long-term survival rate of patients with pancreatic cancer.
