Seeds Fight Brain Tumor -- Research Summary

BACKGROUND: Sometimes, cancer can start in one part of the body and spread to another area. This is known as metastatic cancer. Metastatic cancer has the same name and the same type of cancer cells as the original, or primary, cancer. For example, breast cancer that has spread to the lungs and forms a metastatic tumor is known as metastatic breast cancer. Under a microscope, metastatic cancer cells typically look the same as the original cancer's cells. Nearly all types of cancer, including cancers of the blood and the lymphatic system, can form metastatic tumors. The most common sites of cancer metastasis are the lungs, bones and liver. Some types of metastatic cancer can be effectively treated and cured, but most cannot. However, there are treatments available for all patients with metastatic cancer.

SYMPTOMS: Some patients with metastatic tumors do not have symptoms. Their metastases are found via X-rays or other tests. However, when symptoms of metastatic cancer occur, the type and frequency of the symptoms depend on the size and location of the metastasis. For example, cancer that spreads to the bones will likely cause pain and lead to bone fractures. Cancer that spreads to the brain can cause a variety of symptoms including headaches, seizures and unsteadiness. (SOURCE: National Cancer Institute)

TREATING BRAIN METASTASIS: When cancer spreads to the brain, it can be deadly. Up to 40 percent of the time, the cancer cells return even when a tumor is removed. Now, doctors are using a new treatment to fight cancer that has spread to the brain. Radiation seeds that contain an isotope known as cesium-131 are implanted directly into the brain during the same surgery that is performed to remove the tumor. Cesium-131 is a radioactive isotope with a shorter half-life and higher energy level than other agents in use. The seeds deliver radiation directly to the tumor site after they are implanted. The patient does not have to come in for daily radiation treatments because the seeds release a radiation dose tailored to individual patient needs.
