There exist many different types of orbital cancers. Typically diagnosed by biopsy, few can be completely removed. In these cases, radiation therapy offers a method to treat residual and even clinically undetectable microscopic left over tumor cells. Most of these orbital cancers can be safely cured with relatively low dose radiation that is easily tolerated by the eye. In those cases, the tumor is cured and the eye continues to function. These patient need to be monitored with periodic eye examinations for late occurring radiation complications (eg. cataract, retinopathy, optic neuropathy). However, there also exists orbital cancers that cannot be controlled with low dose irradiation. Many of those cancers will treated by removal of entire orbit (including the eye). This results in no possibility of vision and a poor cosmetic result. When high dose irradiation is needed to spare the eye, vision and improve cosmesis, Dr. Finger utilizes a specialized technique called “Brachytherapy Boost.” This involves temporary surgical placement of radiation sources into part of the orbit to increase treatment of the tumor bed. Then an overlay of external radiation treats the entire orbit. These two types of radiation overlap in the implanted radiation zone, effectively increasing the dose where is it is needed while decreasing irradiation to the normal parts of the eye. Finger’s brachytherapy boost technique has allowed Dr. Finger to improve cosmesis, spare vision and preserve eyes for patients with radiation resistant orbital tumors. This podcast discusses Dr. Finger’s experience with Brachytherapy Boost for tumor control in patients.
