Abstract
Objective To identify the predictive value of sentinel lymph node(SLN) in gastric cancer of different regions and tumor invasion depth. Methods Ninty cases of gastric cancer were multi-point injected with methylene blue dye, and the blue-stained nodes,named SLNs searched in 5-10 minutes,were removed for intraoperative biopsy. All the included patients underwent D2 or D3 gastiectomy. The resected specimens and unstained nodes were sent for pathological examination. Results Of the total 90 patients, SLNs identified in 88 paticnts(97. 8% ) . Among these patients of SLN detected,the sensitivity,accuracy,specificity and false-negative rate were 86.2% (50/58),90. 9% (80/88), 100.0% (30/30) and 13. 8% (8/58),respectively. The sensitivity and accuracy were decreased with the increasing depth of tumor invasion and with the sequence of tumor in lower 1/3 region,middle 1/3 region to upper 1/3 region. Conclusions Sentinel lymph node mapping with methylene blue dye staining in gastric cancer is feasible and reliable. To patients with early stage of gastric cancer,SLN detection has a higher sensitivity and accuracy. And in lower 1/3 region and middle 1/3 region there are higher sensitivity and accuracy than in upper 1/3 region.关键词
