What is a pineocytoma?

A pineocytoma is a tumor of the pineal gland, a small organ in the brain that makes melatonin, a hormone which regulates sleep.  Pineocytomas most often occur in adults as a solid mass, though it may appear to have fluid-filled (cystic) spaces on images of the brain.  Pineocytomas are usually slow-growing and do not usually spread to other parts of the body.[1]  Treatment includes surgery to remove the pineocytoma; most of these tumors do not regrow (recur) after surgery.[2]

How might a pineocytoma be treated?

Because pineocytomas are quite rare, there are no consensus guidelines on the best treatment for these tumors.[3]  However, surgery to remove the entire tumor is considered the standard treatment.  Because these tumors are located deep in the brain, it is important that the risks of surgery in this part of the body be carefully considered in each individual patient.[2]  Radiation therapy has sometimes been used following surgery to destroy any cancer cells that may remain, but the benefit of this additional treatment is questionable.[3]
