Radiation Therapy Lung Cancer Brain Metastases

These therapies can help ease symptoms slow tumor growth and extend life. Brain metastases are not only the most common intracranial neoplasm in adults but also very prevalent in patients with lung cancer.

Small cell lung cancer sclc has a higher propensity than other solid tumors to spread to the brain.

Radiation therapy lung cancer brain metastases. Patients have been grouped into different classes based on the presence of prognostic factors such as control of the primary tumor functional performance status age and number of brain metastases. The rising incidence of patients with lung cancer the importance of radiation therapy for brain metastases is likely to become increasingly recognized in the future. Historically brain metastases have been treated with whole brain radiation therapy.

Stereotactic radiation can be administered for this patient group if total brain radiation already has been delivered. Some metastatic brain tumors appear many years after the primary cancer. Lung cancer is the leading cause of cancer death in men and women worldwide.

Lung cancer often metastasizes to the brain. Others metastasize so quickly that they are identified before the primary cancer. Total brain radiation is administrated for small cell lung cancer even with only 13 metastases due to the high risk of micrometastases outside the visible metastases.

Treatment options for people with brain metastases often include medication surgery stereotactic radiosurgery whole brain radiation therapy or some combination of these. If you or someone you know has lung cancer it. In the meantime further studies are under way to better understand the role of this approach.

Nrg oncology for example is conducting an nci funded trial to test hippocampal avoidance during prophylactic cranial radiation therapy in people with small cell lung cancer in whom brain metastases are particularly common. It has generally been accepted that many cases of brain metastases from lung cancer are indications for palliative treatment3 5 in terms of achieving improvements in neurological. As many as 40 50 of sclc patients will develop brain metastases bm during the course of their disease apart from a higher risk of occurrence than in other cancers bm from sclc have distinct clinical characteristics that differ from bm from all other solid tumors.

Prophylactic preventive cranial irradiation is a whole brain radiation therapy that can help prevent the development of brain metastases and improve survival in patients with limited and extensive stage small cell lung cancer who show a response to treatment with first line chemotherapy or chemotherapy and radiation therapy. If diagnosed and treated early brain metastases usually respond to therapy. However whole brain radiation is associated with cognitive side.

If lung cancer has spread to the brain the prognosis may be unnerving. Treatment is given as a single fraction of 1525 gy. The most common types of cancer that cause metastatic brain tumors are cancers of the lung breast skin colon kidney and thyroid gland.
