The palliative role of radiotherapy in the management of the cancer patient.
Radiotherapy (RT) plays a major role in the palliation of cancer symptoms. Cancer-related bone pain, bronchial obstruction, superior vena cava syndrome, spinal cord compression, and central neurologic dysfunction due to brain metastases are all treated effectively and safely by RT. Although numerous techniques and radiation dose fractionation schemes are used in practice, substantial palliation often may be accomplished by just two to 10 appropriately targeted treatments. Thus, palliative RT regimens need not be highly protracted to be effective. Several new techniques, including strontium 89 radiopharmaceutical therapy, high-dose-rate endobronchial brachytherapy, and stereotactic radiosurgery, are now being evaluated in clinical trials to determine their efficacy in the relief of various oncologic symptoms. Palliative RT continues to be a mainstay of treatment in the management of cancer patients with advanced disease.
