Tamoxifen for salivary gland adenoid cystic carcinoma: report of two cases
- 227 Downloads
Adenoid cystic carcinoma of the salivary gland (ACC-SG) is a slow-growing tumor that is refractory to most chemotherapeutic agents. Estrogen receptor (ER) antagonists provide a novel approach for recurrent disease.
We report two cases of ACC-SC in which Tamoxifen/Toremifene were used.
Both patients obtained long-term stability of disease with no associated toxicity.
Given the relatively unsuccessful treatments for ACC-SC and the low toxicity of ER antagonists, such therapy should be considered in these patients for its potential disease-stabilizing effects.
