What is Adenocarcinoma (salivary duct carcinoma) (AC)?
Adenocarcinoma is a salivary carcinoma characterized by forming glands that mimic breast ductal carcinoma. AC comprises 5-10% of all salivary carcinoma. These tumors are typically high-grade with a high probability of recurrence and/or metastasis.
Who gets AC?
AC occurs in both adults and children.
What causes AC?
The cause of AC is unknown.
How is AC diagnosed?
Typically these present as a lump of the parotid gland, submandibular gland, mouth or throat but salivary duct carcinoma patients more commonly have lymph node metastasis. A diagnosis is made after a biopsy of the affected tissue(s).
What is/is there treatment for AC?
Currently, the standard practice is complete surgical excision. Depending on the location, some patients may also undergo post-operative radiation therapy. However, many patients develop recurrence and/or metastasis in 5 to 10 years.
