人大网膜乳斑与胃癌腹膜种植性转移的相关性研究

The relationship between human great omentum milky spots and peritoneal planting metastasis of gastric carcinoma

目的探讨大网膜乳斑在胃癌腹膜种植性转移中的作用。方法用CH40悬浮液标记大网膜乳斑,于大网膜乳斑区及非乳斑区各切取1 cm×1 cm大网膜组织10块,制成HE染色病理切片,观察乳斑区及非乳斑区癌微转移灶情况。结果51例进展期胃癌患者中30例患者大网膜存在癌微转移灶,此30例中乳斑区均见癌微转移灶,而非乳斑区存在癌微转移灶者仅为3例,乳斑区与非乳斑区相比癌微转移灶的数目有显著差异。结论大网膜乳斑是胃癌腹膜种植性转移的主要部位。

Objective To discuss the function of great omentum milky spots on gastric carcinoma transfered into peritoneum by planting. Methods The great omentum was signed by suspension of CH40. Ten pieces of incisional biopsy tissue of great omentum（ 11 cm^2 ） in great omentum milky spots and no-milky spots were made into pathological sections which were dyed by HE respectively, The transfering place in great omentum milky spots and no-milky spots were observed. Results In this experiment,51 advanced gastric carcinoma patients were observed in clinic. There were 30 patients＇great ornentums had the mlcro-cancer transfering place in milky spots,and only 3 patients had microcaner transfefing place in no-milky spots. This proved that the number of micro-cancer transfering place in milky spots was remarkable different than that in mo-milky spots. Conclusions The great omentum milky spots are the major place in gastric carcinoma transfering into peritoneum by planting.
