Abstract
Objectives: To investigate the relation between metastatic potential of salivary adenoid cystic carcinoma (SACC) and tumor cell-platelet adhesion, and the antimetastatic effect of integrin IIb/IIIa inhibitor on SACC. Methods: Tumor cell-platelet adhesion of highly metastatic SACC-LM, non-highly metastatic SACC-83 and effect of aspirin, arginine-aspartate (RD), magnesium acetylsalicylate on adhesion were studiedin vitro. Antimetastafic effect of aspirin, RD, magnesium acetysalicylate on experimental metastasis of SACC was observedin vivo. Results: The tumor cell-platelet adhesion was stronger in SACC-LM than in SACC-83. Aspirin, RD and magnesium acetylsalicylate could inhibit the adhesion of SACC-LM at the concentration of 1, 5 and 25 µg/ml. RD can inhibit experimental metastasis of SACC. Conclusion: Metastasis of SACC is related to platelet-tumor cell adhesion, RD could inhibit metastasis of SACC.
