Treatment of stage 3 salivary gland cancer
Surgery is the standard treatment for stage 3 salivary gland cancer. The type of surgery will depend on where the tumour is found.
Superficial parotidectomy is used to treat a tumour in the superficial lobe of a parotid gland. The superficial lobe is the part of the parotid gland that is closest to the front of the neck.
Total parotidectomy is used to treat a tumour in the deep lobe of a parotid gland.
Sialoadenectomy is used to treat tumours in the salivary glands in the lower jaw or under the tongue.
Wide local excision is used to treat tumours in the minor salivary glands.
Neck dissection is done for low-grade tumours that have spread to a lymph node or for high-grade tumours.
- Selective neck dissection removes only the lymph nodes where the cancer is most likely to spread. This includes the lymph nodes close to and on the same side of the neck as the salivary gland tumour.
- Radical neck dissection removes all of the lymph nodes around and on the same side of the neck as the salivary gland tumour. Other tissues are sometimes removed if the cancer has spread to them.
Reconstructive surgery may be needed after surgery for stage 3 salivary gland cancer. This may include skin, tissue and nerve grafts.
Radiation therapy @(Model.HeadingTag)>
External radiation therapy is given after surgery if:
- there are cancer cells in the tissue that was removed along with the tumour (positive margins)
- the cancer is high-grade
- the cancer has spread to the space around a nerve (perineural invasion)
- the cancer has spread to the lymph nodes
External radiation may be offered instead of surgery for stage 3 salivary gland cancer if surgery to remove the tumour would cause a major change in your appearance or make it difficult for you to talk or eat. It may also be used if you aren't healthy enough to have surgery or if you don't want to have surgery.
Intensity-modulated radiation therapy (IMRT) is the most common type of external radiation therapy used to treat stage 3 salivary gland cancer.
