Percutaneous transhepatic cholangial drainage combined with intra-tumoral iodine-125 seeds implantation and chemotherapy for locally progressive pancreatic head cancer with obstructive jaundice.

Purpose:To investigate the clinical efficacy of percutaneous transhepatic cholangial drainage (PTCD) combined with intra-tumoral iodine-125 (125I) particle implantation and chemotherapy in the treatment of locally advanced pancreatic head cancer (LAPHC) with obstructive jaundice. Material and methods:Twenty-one patients with LAPHC with obstructive jaundice were selected, and routine examination before surgery to determine location of obstruction and degree of bile duct dilatation was performed. All 21 patients underwent PTCD first, and usual examinations, including liver and kidney function, were re-examined after operation. When the liver function recovered significantly, patients were treated with seed implantation and systemic chemotherapy after surgery. Clinical efficacy and complications of 21 patients were observed, and changes in survival time and serum level of tumor markers were analyzed. Results:After combined treatment, there were 3 cases of complete response (CR), 12 cases of partial response (PR), 3 cases of stable disease (SD), and 3 cases of progressive disease (PD) in 21 patients. The overall effective rate was 71.43%, and the local control rate was 85.71%. The pain relief was statistically significant one month after treatment, compared with that before treatment (VAS scores: 6.76 ±2.25 vs. 3.25 ±1.92, p < 0.001), and the rate of pain relief was 71.43% (15/21). In all patients, jaundice, abdominal pain, and abdominal distension improved to different degrees after surgery, and the skin pruritus disappeared. Bilirubin and transaminase improved to varying degrees 3 days, 1 week, and 4 weeks after treatment (p < 0.05). Cancer antigen 199 (CA-199), carcinoembryonic antigen (CEA), and cancer antigen 125 (CA-125) after combination therapy, achieved statistically significant differences (t = 9.525, 10.378, 3.262, respectively, p < 0.05). The overall survival time of 21 patients was 11.6 months, ranging from 3.9 to 22.6 months. Conclusions:For LAPHC patients with obstructive jaundice, PTCD combined with particle implantation and chemotherapy is clinically effective in improving the quality of life and prolonging survival.
