Objective: The objective of the study was to identify the advantages of interstitial radioactive seed implantation for the treatment of Stage III pancreatic cancer.
Materials and Methods: 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.
Results: 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.
Conclusions: Radioactive seed implantation obviously advantageous for the treatment of Stage III pancreatic cancer.

间质放射性粒子植入治疗Ⅲ期胰腺癌的优势


目的：本研究的目的是确定间质放射性粒子植入治疗 III 期胰腺癌的优势。
材料与方法：回顾性分析160例植入放射性粒子的胰腺癌患者的临床资料。根据肿瘤大小、淋巴结转移、肿瘤对重要血管的侵犯情况对患者进行分组，统计生存时间。
结果：I期患者术后平均生存时间（月）为24.80，II期为12.89，III期为13.51，IV期患者为7.49，II期和III期患者的差异无统计学意义。放射性粒子植入治疗胰腺癌的疗效与肿瘤大小和淋巴结转移数量密切相关，但与肿瘤对血管的侵袭不显着相关。
结论：放射性粒子植入治疗Ⅲ期胰腺癌具有明显优势。
