The role of radiotherapy in palliative care.

Radiotherapy is an indispensable modality in the palliation of cancer. All palliative care programs should be acquainted with its indications and have a close working relationship with a radiation oncology department. The technical aspects of the subject may be intimidating to many staff and patients, and departments need to improve their outreach and education. The main indications are: pain relief (particularly bone pain), control of hemorrhage, fungation and ulceration, dyspnea, blockage of hollow viscera, and the shrinkage of any tumors causing problems by virtue of space occupancy. In addition, it has an important role in the palliation of three oncological emergencies: superior vena caval obstruction, spinal cord compression, and raised intracranial pressure due to cerebral metastases. More pragmatic fractionation schedules are being developed that are compatible with good results in terms of palliative end points, giving shorter courses with fewer hospital attendances for patient and family comfort and convenience. More clinical research and evaluation of palliative radiotherapy are required.
