  • Objective  To study the characteristics of lymph vessel in gast ric cancer and it s relationship with lymph node metastasis (LM) . Methods  Lymph vessel in normal, peripheral, cent ral region of 70 primary human gast ric cancer were investigated by IHC staining for D2240. The relation between lymph vessel density (LVD), lymph vessel mean area (LVMA), lymph vessel mean diameter (LVMD), lymph vessel invasion (LVI) and LM were analysed. Results  Compared with the normal region of gast ric canc2 er, the LVD of peripheral region of gast ric cancer is significantly high (41. 32 ±15. 62 vs 30. 06 ±11. 86, P = 0. 000 ), and there was a significant decrease in LVMA (802. 12 ±728. 09μm2 vs 1511. 28 ±1301. 21 μm2, P = 0. 000) and LVMD (132. 35 ±65. 76μm vs 196. 19 ±103. 72μm, P = 0. 000) . The LVD (43. 67 ±16. 42 vs 33. 38 ±9. 02, P = 0. 019), total area (35866. 71 ±19678. 53μm2 vs 23933. 34 ±15405. 2μm2, P = 0. 029 ), total perimeter (5851. 28 ±1897. 13μm vs 4173. 56 ±2028. 18μm, P = 0. 003), mean area (1050. 31 ±765. 47μm2 vs 723. 76 ±534. 75μm2, P = 0. 000), mean perimeter (161. 90 ±77. 13μm vs 123. 01 ±60. 88μm, P = 0. 000) of lymphatics in peripheral region of gast ric cancer with LM was signifi2 cantly increased than that of gast ric cancer without LM. The prediction of LM for gast ric cancer by LVI is in common with routine pathology ( P = 0. 125, κ= 0. 822 > 0. 7, P = 0. 000) . Conclusion  Lymphangio2 genesis exist s in peripheral region of gast ric cancer, and the lumina of newly formed lymphatics are much small, therefore the lymphocinesia of that region is inadequate. Malignent cells may penet rate the lym2 phatics and get into lymphocinesia via dest royed part s of endothelium in peripheral region of gast ric carci2 noma. Increased LVD and LVI were significantly associated with LM, and may play an important role in detecting LM in gast ric cancer and the decision making process for additional surgery.
