Which gland is most commonly affected in adenoid cystic carcinoma?

·

What is the cause of adenoid cystic carcinoma?

The underlying cause of adenoid cystic carcinoma (ACC) is not yet known, but it appears to develop from non-inherited, genetic changes that occur during a person’s lifetime.

Where does adenoid cystic carcinoma spread?

Regardless of where it starts, AdCC tends to spread along nerves, known as a perineural invasion, or through the bloodstream. It spreads to the lymph nodes in about 5% to 10% of cases. If it spreads to another part of the body beyond the lymph nodes, it is called metastatic cancer.

What feature is frequent in adenoid cystic carcinoma?

ACC is an uncommon neoplasm that most frequently arises in salivary glands and related tissue in the head and neck region. ACC has distinct histologic features, with cribriform and tubular growth patterns of basaloid cells displaying a predominantly myoepithelial cellular phenotype.

What is cystic carcinoma?

Listen. Adenoid cystic carcinoma (ACC) is a rare form of adenocarcinoma, a type of cancer that begins in glandular tissues . It most commonly arises in the major and minor salivary glands of the head and neck. It can also occur in the breast, uterus, or other locations in the body.

How long can you live with adenoid cystic carcinoma?

The 5-year survival rate tells you what percent of people live at least 5 years after the cancer is found. Percent means how many out of 100. The 5-year survival rate for people with AdCC is approximately 89%. The 15-year survival rate for people with AdCC is approximately 40%.

Is adenoid cystic carcinoma aggressive?

Adenoid cystic carcinoma is an aggressive salivary gland tumor known for local and lymphovascular invasion, perineural extension, and association with delayed metastases.

Is adenoid cystic carcinoma terminal?

Due to its slow growth, ACC has a relatively indolent but relentless course. Unlike most carcinomas, most patients with ACC survive for 5 years, only to have tumors recur and progress. In a recent study of a cohort of 160 ACC patients, disease specific survival was 89% at 5 years but only 40% at 15 years.

Is adenoid cystic carcinoma curable?

Compared with most other carcinomas, adenoid cystic carcinoma has a slow course with a survival rate of 89 percent at five years. Tumors progress persistently and often recur, resulting in a survival rate of only 40 percent after 15 years. Doctors treat adenoid cystic carcinoma as a chronic condition.

Can adenoid cystic carcinoma be completely cured?

Occasionally, it is not possible to remove AdCC using surgery. This type of tumor is called inoperable. In these cases, your doctor will recommend other treatment options, such as radiation therapy or medications (see below).

Is adenoid cystic carcinoma caused by HPV?

However, adenoid cystic carcinoma of the uterine cervix has been associated with other HPV-related lesions,13 and high-risk HPV types 16, 31 and 33 have been detected in some of these tumors.

Is adenoid cystic carcinoma slow growing?

Adenoid cystic carcinoma (ACC) of salivary glands is a slow-growing malignant tumor, characterized by wide local infiltration, perineural spread, a propensity to local recurrence and late distant metastasis.

Can adenoid cystic carcinoma cause jaw pain?

The most common craniofacial pain locations included the throat, left mandible, right mandible, and left temporomandibular joint/ear region and the teeth.” Another 60 patients in the study (32%) reported craniofacial pain along with pain in other regions.
