Your question: Is adenoid cystic carcinoma malignant?

What type of cancer is adenoid cystic carcinoma?

Adenoid cystic carcinoma (AdCC) is a rare form of adenocarcinoma, which is a broad term describing any cancer that begins in glandular tissues.

Can adenoids become cancerous?

Adenoid cystic carcinoma (ACC) is a relatively rare form of cancer that most commonly develops in the salivary glands or other regions of the head and neck. ACC can occur in other parts of the body, such as the breast, skin, cervix in females, prostate gland in males, and various other areas.

Can you survive adenoid cystic carcinoma?

The 5-year survival rate for people with AdCC is approximately 89%. The 15-year survival rate for people with AdCC is approximately 40%. A late recurrence of AdCC is common and can occur many years after initial treatment.

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).

How aggressive is adenoid cystic carcinoma?

Adenoid cystic carcinoma is an aggressive disease, with added complexity when involving the skull base. A strategy of maximal resection with adjuvant radiotherapy should be used to optimize survival. Chemotherapy does not appear to confer benefit.

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.

Why adenoid cystic carcinoma is called Cylindroma?
