Adenoid cystic carcinoma (ACC cancer) is a rare cancer that most commonly affects the salivary glands. The throat, mouth, lacrimal glands (tear glands) and other areas of the body, such as the breasts or prostate gland, can also be affected. Wherever it’s located, ACC cancer can spread along nerves and can be difficult to get rid of entirely.
For patients with ACC cancer in the skull base—the bones and structures that form the bottom of the head and the area just behind the eyes and nose—surgical tumor removal can be especially difficult. But at Tampa General Hospital’s Neuroscience Institute and Ear, Nose and Throat Institute, our multidisciplinary team of surgeons expertly treat ACC cancer and other types of skull base tumors with state-of-the-art technology. In fact, TGH has been ranked by U.S. News & World Report in the top 10% of hospitals in the nation for Neurology & Neurosurgery in 2022-23.
Adenoid Cystic Carcinoma Causes
There are no known causes of adenoid cystic carcinoma. However, as with many other types of cancer, genetic mutations are believed to be the underlying basis of malignant tumor development.
Adenoid Cystic Carcinoma Symptoms
Symptoms of ACC cancer will vary depending on the location of the malignancy. When adenoid cystic carcinoma affects the salivary glands or other structures in the skull base, symptoms can include:
- Facial Pain
- Facial drooping
- Numbness in the lips or other areas of the face
- Vision changes
- Eye bulging
- Pain and Swelling
Diagnosing Adenoid Cystic Carcinoma
Diagnosing ACC cancer typically begins with a detailed medical history, a physical examination, and lab tests. A variety of other tests will likely be performed to confirm the presence of adenoid cystic carcinoma and may include:
- Biopsies – removal of a small tissue sample of the suspected tumor for evaluation by a pathologist
- CT scan – a series of computerized X-rays that create a film of cross-sectional images of bones, tissues and organs
- MRI – images generated with a powerful magnet and radio waves that create visual cross sections of bones, tissues and organs
- PET scan – a test that uses an injectable radiotracer to create 3D images of organs
Adenoid Cystic Carcinoma Treatment
Treating adenoid cystic carcinoma usually involves skull base surgery to remove tumors and some surrounding tissue, to ensure that the cancer has not spread beyond the tumor itself. Sometimes a portion of a facial nerve may need to be removed during surgery, which can lead to facial drooping. Reconstructive surgery to address the dropping may be an option for some patients.
In cases where cancer is thought to have spread but hasn’t been seen, or a tumor cannot be entirely removed without damaging other organs, radiation therapy may be recommended.
