Schwannoma Treatment

Surrounding the nerves in the human body is a layer of tissue called the nerve sheath. Contained within this tissue are cells called schwann cells. The cells can develop into a benign tumor called a schwannoma, the most common of which is an acoustic neuroma. At times, although rarely, these tumors can be malignant, and can occur anywhere in the body. The most common areas are the sciatic nerve, the brachial plexus (top of the arm), and the sacral plexus (lower back).Treatment is relegated to standard cancer treatment such as chemotherapy, radiation therapy, and surgery.

  1. Types and Symptoms

    • In addition to the acoustic neuroma (vestibular schwannoma), which grows on the eighth cranial nerve, several other types of schwannoma's exist. They include perineal schwannomas, which effect the nerves between the legs; malignant peripheral nerve sheath tumors (neurofibrasarcomas), which is a form of soft tissue sarcoma; and schwannomatosis, an incredibly rare form of neurofibromatosis (a genetic condition that affects nerve cells).

      Schwannomatosis can develop on head, spine, and limb nerves, and the main symptom is the pain associated with the nerve that is effected. Additionally, while those with neurofibromatosis have the potential of going deaf as a symptom, this does not occur. The symptoms of other forms of schwannomas are dependent on the location and severity of the tumor.

    Surgery

    • Given that the majority of schwannomas are benign, simple, minimally invasive surgery is recommended for removal. Complete excision of the tumor results in a slim to no chance of recurrence.

      In the case of the most common form of schwannoma, acoustic neuroma, surgery is dependent on the size and location of the tumor as well as how much of the hearing has been affected.

    Radiotherapy and Chemotherapy

    • In the rare event that the schwannoma becomes malignant, chemotherapy and radiation therapy may be employed. Chemotherapy involves the use of anti-cancer drugs administered intravenously. Radiation therapy involves the use of high-energy beams aimed directly at the tumor in highly concentrated doses. Both contain side effects such nausea, headaches, vomiting and an overall feeling of malaise.
