abstractsObjective:To investigate the safety and short-term efficacy of yttrium-90 [ 90Y] resin microspheres transarterial radioembolization (TARE) for the treatment of initial unresectable malignant hepatic tumor. Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 10 patients with initial unresectable malignant hepatic tumor who were admitted to The First Affiliated Hospital of Army Medical University from June 2022 to June 2023 were collected. All patients were males, aged (57±4)years. Measurement data with normal distribution were represented as Mean± SD, and comparison before and after treatment within the group was conducted using the paired t test. Measurement data with skewed distribution were represented as M( Q1, Q3) or M(range), and comparison before and after treatment within the group was conducted using the paired rank sum test. Count data were described as absolute numbers or proportions. Results:(1) Pre-treatment assessment. All 10 patients completed pre-treatment assessment, with 8 cases undergoing once of technetium 99-polymerised protein perfusion test and 2 cases under-going ≥ twice of technetium 99-polymerised protein perfusion test. The ratio of uptake of techne-tium 99-polymerised protein in tumor tissue to normal tissue, the hepatopulmonary shunting ratio and the therapeutic requirement of 90Y resin microspheres in 10 patients were 5.8±1.2, 4.8%±0.8% and (1.10±0.20)GBq, respectively. (2) Treatment strategy of 90Y resin microspheres TARE. Of the 10 patients, cases treated with whole tumor radioembolisation, radioembolisation of the main target lesion+non-target lesion radiofrequency ablation, radioembolisation of the main target lesion+non-target lesion iodine-125 particles implantation, radioembolisation of the liver lobe or liver segment were 6, 2, 1, 1, respectively. During the treatment period, one elderly case did not receive target therapy combined with immunotherapy due to intolerance, and the remaining 9 cases received target therapy combined with immunotherapy. Of the 10 patients, there were 7 cases receiving once of 90Y resin microspheres TARE, and 3 cases receiving twice of 90Y resin microspheres TARE. (3) Follow-up. All 10 patients were followed up for 4.5(range, 3.0-12.0)months. During the follow-up, none of patient had adverse event associated with 90Y resin microspheres TARE. The tumor diameter, alpha-fetoprotein (AFP), abnormal prothrombin, alanine aminotransferase (ALT), aspartate amino-transferase (AST), albumin (Alb), total bilirubin (TBiL), glutamyltransferase (GGT) of the 10 patients were 96(72,135)mm, 26(6,833)μg/L, 290(56,2 997)Au/L, (36±13)IU/L, (41+16)IU/L, (40±4)g/L, (15.3±4.1)μmol/L, (99±68)IU/L before receiving 90Y microspheres TARE. The above indicators of the 10 patients were 63(43,97)mm, 4(3,357)μg/L, 38(25, 142) Au/L, (40±16)IU/L, (51±28)IU/L, (39±4)g/L, (14.4±1.2) μmol/L, (134±93)IU/L after 90 days of receiving 90Y microspheres TARE. There were significant differences in tumor diameter and abnormal prothrombin ( Z=-2.08, -2.24, P<0.05) and there was no significant difference in AFP, ALT, AST, Alb, TBil, GGT ( Z=-1.27, t=0.63, 1.69, 1.73, 0.67, 1.30, P>0.05). During the follow-up period, 5 cases achieved clinical complete response, 4 cases achieved clinical partial remission, and 1 case experienced non-target lesion progression within 30 days after receiving 90Y resin microspheres TARE. The disease remission rate and disease control rate of the 10 patients were 9/10 and 9/10, respectively. None of patient died during follow-up period. Conclusion:90Y resin microspheres TARE for the treatment of initial unresectable malignant hepatic tumor is safe and feasible, and can achieve satisfactory short-term efficacy when combined with other treatment methods.
