ABSTRACT
BACKGROUND: This study aimed to evaluate the clinical efficacy of coaxial percutaneous Iodine-125 (125I) seed implantation in combination with arterial infusion chemotherapy for the treatment of advanced pancreatic cancer (PC) through a randomized controlled trial. METHODS: A total of 101 patients with advanced PC were randomized into two groups: control group treated with systemic intravenous chemotherapy and experimental group that received 125I seed implantation in combination with arterial infusion chemotherapy. Outcomes, including tumor control, abdominal pain relief, and survival time were compared between these two groups (Trial Registration No. KYKT2018-65). RESULTS: Pretreatment abdominal pain scores were comparable between the two groups, whereas the abdominal pain scores at 1- and 3-month post-treatment were significantly lower in the control group than those in the experimental group (1-month: 3.74 ± 1.54 vs. 4.48 ± 1.46, p = .015; 3-month: 3.64 ± 2.21 vs. 5.40 ± 1.56, p < .001). At 3-month post-treatment, computed tomography (CT) scan revealed a significantly higher disease control rate in the experimental group than that in the control group (94.0% vs. 74.5%, p = .007). The median survival time in the experimental group was significantly longer than that in the control group (15-month vs. 9-month, p < .001). CONCLUSION: The combination of coaxial percutaneous 125I seed implantation with arterial infusion chemotherapy could significantly alleviate abdominal pain, improve tumor control rates, and prolong survival time in patients with advanced PC.

OBJECTIVE: To study intermediate and long term efficacy of uterine arterial embolization (UAE) with sodium alginate microspheres (KMG) at diameters 500-00 microm in treatment of diffuse adenomyosis. METHODS: Totally 40 patients with standard diffuse adenomyosis were enrolled and treated with UAE. KMG at diameters 500-700 microm for vascular embolization were used to embolize the arteries. The degree of dysmenorrhea, amount of menorrhea and uterine volume, as well as the level of serum CA125, follicle stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2) were investigated before and after UAE. RESULTS: The follow up rates were 100% (40/40), 100% (40/40), 80% (32/40), 68% (27/40), 58% (23/40) after uterine arterial UAE 12, 24, 36, 48 and 60 months respectively. The early, intermediate and long-term effective rates were 90% (36/40), 88% (28/32), 83% (19/23). The degree of dysmenorrhea, the amount of menorrhea and the uterine volume, as well as serum CA125 all decreased significantly 3 months after UAE at varying degrees (P < 0.05). Compared with other follow-up time, the degree of dysmenorrhea and the amount of menorrhea declined to their lowest point at 6 month after UAE (P < 0.01). Paralleled with the decrease of volume of uterine, serum CA125 also decreased significantly and reached the lowest level 12 months later compared with other follow-up times (P < 0.01). Even at the 12th month after UAE serum CA125 was not normal and FSH, LH and E2 did not change all the times after UAE, (P > 0.05). No recurrence was found during the 60 months after UAE. CONCLUSION: KMG used in UAE at diameters 500-700 microm has good intermediate and long term effectiveness in treatment of diffuse adenomyosis with no side effects.
