Salivary gland carcinoma treated with concomitant chemoradiation with intraarterial cisplatin and docetaxel

Abstract

Malignant neoplasms of the salivary gland are uncommon entities in which surgical resection of the primary lesion has been accepted as a standard therapeutic option. The efficacy of radiation and systemic chemotherapy has been limited for patients with recurrent, metastatic, or unresectable disease because of unfavorable response rates and the short duration of the response. We treated one patient with recurrent adenoid cystic carcinoma arising from the sublingual gland and one patient with primary adenocarcinoma arising from the parotid gland with transfemoral intraarterial chemotherapy, based on full-dose cisplatin and docetaxel and concurrent external-beam radiotherapy. The doses of cisplatin and docetaxel in the two patients were 80–100 mg/m² and 10–15 mg/m², respectively. Docetaxel was infused first, followed by cisplatin. Both patients obtained complete responses. Although complications such as mucositis, anorexia, neutropenia, and ischemic colitis were observed, they were well tolerated and manageable. The concomitant chemoradiotherapy of cisplatin and docetaxel seemed to be a practicable option for patients with recurrent and unresectable salivary gland carcinomas.
