125I implantation under CT guidance for advanced pancreatic cancer / 中华内分泌外科杂志

ABSTRACT

Objective:To evaluate the clinical value of 125I seed implantation guided by CT in treatment of advanced pancreatic cancer. Methods:The data of 63 patients with advanced pancreatic cancer in the Affiliated Cancer Hospital of Zhengzhou University from Jun. 2015 to Jun. 2018 (48 males and 15 females) were retrospectively analyzed. All patients underwent CT-guided 125I seed implantation, and regular follow-up after operation. All patients were followed up for 3 to 36 months to evaluate the clinical efficacy, including the volume of cancer before and after treatment, tumor marker CA199 and changes in complications such as abdominal pain and jaundice, and the survival status of the patients. Results:Three months after seed implantation, 9 cases (14.3%) had complete remission of cancer in 63 patients, 33 cases had partial remission (52.4%) , 15 cases had no change (23.8%) , and 6 cases had disease progression (9.5%) . The total effective rate was 67.7%. Three months after treatment, the volume of cancer was (31.92±14.93) cm 3, which was significantly smaller than that before treatment [ (44.88±16.19) cm 3; t=6.79, P<0.01]. Three months after treatment, Serum CA199 (77.21±58.69 U/ml) was significantly lower than that before treatment (327.76±110.42) U/ml ( t=16.56, P<0.05) . 125I seed implantation for advanced pancreatic cancer had an average survival period of (13.04±0.92) months and a median delivery period of 11 months. Of the 57 patients with different degrees of abdominal pain, 49 were better than before, and the pain relief rate was 85.9%. Among 42 patients with jaundice symptoms of varying degrees, 31 were better than before, and the jaundice remission rate was 73.8%. There were no serious complications related to treatment in any patients. Conclusion:125I seed implantation therapy can safely and effectively treat advanced pancreatic cancer, and improve related clinical symptoms such as abdominal pain and jaundice.
