Abstract
The objective of the study was to identify the advantages of interstitial radioactive seed implantation for the treatment of Stage III pancreatic cancer. Clinical data of 160 patients with pancreatic cancer implanted with radioactive seeds were retrospectively analyzed. Patients were grouped according to tumor size, lymph node metastasis, and tumor invasion to important blood vessels, and survival time statistics were obtained. The mean postoperative survival time (months) was 24.80 for Stage I, 12.89 for Stage II, 13.51 for Stage III, and 7.49 for Stage IV patients, and the difference between Stage II and Stage III patients was not statistically significant. The efficacy of radioactive seed implantation therapy for pancreatic cancer was strongly associated with tumor size and number of lymph node metastases but not significantly associated with tumor invasion to blood vessels. Radioactive seed implantation obviously advantageous for the treatment of Stage III pancreatic cancer.
