Evaluation of the efficacy of gastric lymphoma treated with non-surgical therapy using oral and double contrast-enhanced gastric ultrasonography.
Aim: To investigate the feasibility of assessing the ecacy of non-surgical treatment for gastric lymphoma using oral contrast-enhanced ultrasound (OCEUS) and double contrast-enhanced ultrasound (DCEUS).
Material and methods: A total of 27 patients with gastric lymphoma treated nonoperatively were included in this retrospective study. The ecacy was evaluated using OCEUS and CT, respectively, and the results were tested for kappa concordance. Sixteen of the 27 patients underwent multiple DCEUS examinations before and after treatment. Micro-perfusion of the lesion in DCEUS is represented by the Echo Intensity Ratio (EIR), (echo intensity of the lymphoma lesion/echo intensity of the normal gastric wall), and one-way ANOVA was used to compare the differences between groups in EIR values before and after treatment.
Results: OCEUS and CT were highly consistent in assessing the efficacy of gastric lymphoma, with a Kappa value of 0.758. During a median follow-up of 8.8 months, there was no statistical difference between the complete remission rate obtained by OCEUS and that obtained by endoscopic and CT (25.93% vs. 44.44%, p=0.154; 25.93% vs. 33.33%, p=0.766). There was also no statistical difference in the time to achieve complete remission using OCEUS assessment and endoscopy and CT (4.71±1.03 months vs. 6.01±2.14 months, p=0.088; 4.47±1.84 months vs. 6.01±2.14 months p=0.143). The difference in EIR between the groups before treat-ment and after different numbers of treatments was statistically signifficant (p<0.05), and post hoc analysis revealed this dif-ference as early as after the second treatment (p<0.05).
Conclusions: Transabdominal OCEUS and CT are comparable in the assessment of gastric lymphoma treatment ecacy. DCEUS is a noninvasive, cost-effective, and widely available method for gastric lymphoma therapeutic effect evaluation. Therefore, transabdominal OCEUS and DCEUS have the potential to be used for the early assessment of the ecacy of the non-surgical treatment of gastric lymphoma.
期刊介绍：
The journal aims to promote ultrasound diagnosis by publishing papers in a variety of categories, including editorial letters, original papers, review articles, pictorial essays, technical developments, case reports, letters to the editor or occasional special reports (fundamental, clinical as well as methodological and educational papers).
The papers published cover the whole spectrum of the applications of diagnostic medical ultrasonography, including basic science and therapeutic applications.
The journal hosts information regarding the society''s activities, scheduling of accredited training courses in ultrasound diagnosis, as well as the agenda of national and international scientific events.
