BACKGROUND AND AIM: We have reported the characteristics of magnified endoscopic images of @entity356 -associated lymphoid tissue (MALT) @entity706 before and after treatment. In this study, we investigated the diagnostic efficacy of magnified endoscopic images for target biopsy and evaluation of clinical remission. METHODS: Twenty-one @entity1 diagnosed with localized @entity6595 were enrolled. Magnified endoscopy was performed prior to treatment and at a mean period of 1.8 months (1-6 months) after therapy ( @entity1534 eradication in 19 @entity1 and radiation therapy in two @entity1 ). Microstructural pattern and abnormal vessels in the lesions were assessed, and corpus mucosa without @entity706 was divided into @entity1534 -negative mucosa and @entity1534 -positive mucosa. Biopsy was the gold standard in this study. RESULTS: Nonstructural areas with abnormal vessels were observed in all @entity1 before treatment. Fifteen @entity1 achieved pathological complete remission. Disappearance of nonstructural areas and abnormal vessels after therapy was associated with pathological remission. Sensitivities of these findings for diagnosis were 76.9% and 85.7%, respectively, and the specificities were 87.5% and 85.7%, respectively. @entity1534 eradication therapy was invalid in three @entity1 with @entity1534 -negative mucosa in magnified images. CONCLUSIONS: Magnifying endoscopy may be useful for target biopsy of superficial @entity6595 in clinical management.
