ABSTRACT
BACKGROUND: Preoperative diagnosis rate of pancreatic cancer has increased year by year. The prognosis of pancreatic cancer patients with unexpected liver metastasis found by intraoperative exploration is very poor, and there is no effective and unified treatment strategy.
AIM: To evaluate the therapeutic effect of radioactive 125I seed implantation for pancreatic cancer patients with unexpected liver metastasis.
METHODS: The demographics and perioperative outcomes of patients who underwent 125I seed implantation to treat pancreatic cancer with unexpected liver metastasis between January 1, 2017 and June 1, 2019 were retrospectively analyzed. During the operation, 125I seeds were implanted into the pancreatic tumor under the guidance of intraoperative ultrasound, with a spacing of 1.5 cm and a row spacing of 1.5 cm. For patients with obstructive jaundice and digestive tract obstruction, choledochojejunostomy and gastroenterostomy were performed simultaneously. After operation, the patients were divided into a non-chemotherapy group and a chemotherapy group that received gemcitabine combined with albumin-bound paclitaxel treatment.
RESULTS: Preoperative imaging evaluation of all patients in this study showed that the tumor was resectable without liver metastasis. There were 26 patients in this study, including 18 males and 8 females, aged 60.5 ± 9.7 years. The most common tumor site was the pancreatic head (17, 65.4%), followed by the pancreatic neck and body (6, 23.2%) and pancreatic tail (3, 11.4%). Fourteen patients (53.8%) underwent palliative surgery and postoperative pain relief occurred in 22 patients (84.6%). The estimated blood loss in operation was 148.3 ± 282.1 mL and one patient received blood transfusion. The postoperative hospital stay was 7.6 ± 2.8 d. One patient had biliary fistula, one had pancreatic fistula, and all recovered after conservative treatment. After operation, 7 patients received chemotherapy and 19 did not. The 1-year survival rate was significantly higher in patients who received chemotherapy than in those who did not (68.6% vs 15.8%, P = 0.012). The mean overall survival of patients in the chemotherapy group and non-chemotherapy group was 16.3 mo and 10 mo, respectively (χ 2 = 7.083, P = 0.008).
CONCLUSION: Radioactive 125I seed implantation combined with postoperative chemotherapy can prolong the survival time and relieve pain of pancreatic cancer patients with unexpected liver metastasis.
