Summary |
Introduction |
Salivary duct carcinoma is one of the rarest and most aggressive forms of parotid tumor. We report two cases.
Cases |
Case 1: a 78-year-old man was referred for a salivary duct carcinoma of the left parotid gland. Treatment was surgical (parotidectomy with ipsilateral selective neck dissection), without capsule rupture, and with healthy margins. At seven years’ follow-up, the patient was alive and disease-free.
Case 2: a 41-year-old man was referred for a salivary duct carcinoma of the left parotid gland. Parotidectomy with ipsilateral selective neck dissection left healthy but insufficient margins (<1cm), and postoperative radiation therapy (70Gy) was undertaken. At eight years’ follow-up, the patient was alive and free of recurrence.
Discussion |
Mean patient age in the literature is 60years, with a male-to-female ratio of 2:1. Mean five-years’ recurrence-free survival was 34%.
Conclusion |
Surgery is the main form of treatment in this indication. Postoperative radiation therapy is indicated in case of extraparotid extension, pathological resection margins, cervical lymph node metastasis, lymphatic embolus and/or neurologic invasion. Chemotherapy is generally reserved for metastatic forms of the disease.
