Gastric Adenocarcinoma of Fundic Gland Type with Aggressive Transformation and Lymph Node Metastasis: a Case Report

A 55-year-old man visited our hospital for a detailed examination of a gastric submucosal tumor that was first detected 10 years prior. The tumor continued to grow and had developed a depressed area in its center. A histopathological examination of biopsy specimens revealed gastric adenocarcinoma of the fundic gland type (GA-FG). It was diagnosed as T2 based on the invasion depth as determined by white-light endoscopy and endoscopic ultrasonography. A total gastrectomy with lymphadenectomy was performed and a GA-FG in the mucosa and submucosa was confirmed histopathologically. However, there was a gradual transition to an infiltrative tubular adenocarcinoma with poorly differentiated components in the muscular and subserosal layers. Metastasis was identified in a dissected lymph node (LN). This is the first report of a GA-FG progressing to an aggressive cancer with LN metastasis. These findings modify our understanding of the pathophysiology of GA-FG.

Suppressive effects of GTW treatment on mesangial lesions in experimental irreversible glomerulosclerosis / 中国中药杂志

<p><b>OBJECTIVE</b>To examine suppressive effects of multi-glycoside of Tripterygium wilfordii Hook. f. (GTW)on mesangial injury induced by two-injecti on of anti-Thy1. 1 monoclonal antibody(mAb) 1-22-3 in vitro.</p><p><b>METHOD</b>We established the irreversible model of glomerulosclerosis with anti-Thy1. 1 mAb 1-22-3. After 42 days of oral treatment with GTW (50 mg x kg(-1) BW)and vehicle (distilled water), to observe effects of GTW on proteinuria, renal function, mesangial morphological change, and mRNA expressions of collagen type I and TGF-beta by light microscope (LM), immunofluorescence (IF), and Reverse Transcription Polymerase Chain Reaction (RT-PCR).</p><p><b>RESULT</b>GTW ameliorated proteinuria (from day24 to day 42) and mesangial proliferation [total cell number, GTW group 65.67+/-3.43 vs. control group 87.02+/-2.41, P < 0.05; matrix expansion, GTW group 1.20+/-0.06 vs. control group 2.77+/-0.23, P < 0.05; alpha-smooth muscle actin(alpha-SMA) expression, GTW group 1.75+/-0.33 vs. control group 2.62+/-0.15, P < 0.05; collagen type I expression, GTW group 1.68+/-0.31 vs. control group 2.06+/-0.24, P < 0.05], moreover, significantly reduced the glomerular expression of mRNA for collagen type 1(53.5% to the control group, P < 0.05)and TGF-beta(14.7% to the control group, P < 0.05)on day 42day.</p><p><b>CONCLUSION</b>GTW can not only decrease proteinuria, but also ameliorate mesangial alterations probably by the reduction of cytokines. GTW may be a promising agent for the prevention of progressive and irreversible glomerulosclerosis.</p>
