Palliative Radiotherapy Referrals in the Last Days of Cancer Patients' Life: Could We Do Better?

PURPOSE/OBJECTIVE(S) The role of active cancer therapy towards the end of life (EOL) is debatable and may even be considered harmful. While palliative radiotherapy may be highly effective in reducing cancer-related symptoms of advanced disease, the beneficial effects are usually at least 2-4 weeks from completion of treatment. Thus, radiotherapy administered at the end of life is often ineffective, and may actually impair quality of life and be associated with an unnecessary burden to the health care system. The universal Israeli health care system enables the administration of radiotherapy without financial or regulatory barriers, even at EOL. We aimed to assess the use radiotherapy towards EOL in a tertiary care Israeli cancer center. MATERIALS/METHODS We retrospectively analyzed data of patients receiving palliative radiation and died within 30 days of their simulation from March 2019 until September 2020. RESULTS Out of approximately 2,000 patients treated with radiotherapy during the study period, 148 (8%) patients were referred for palliative radiation and died within 30 days of their simulation. The majority (88, 59.5%) were male, the median age was 67.3 years and the most common malignancies patients suffered from were lung cancer (49, 33.1%), gastrointestinal tumors (28, 18.9%), genito-urinary malignancies (23, 15.5%) or breast cancer (15, 10.1%). The median ECOG PS was 3. Nineteen patients (12.8%) did not initiate radiation treatment plan, 24 patients (16.2%) completed less than half of the planned treatment and 89 patients (60.1%) completed the entire duration of treatment. Of the patients who completed the planned therapy, 34 patients (38.2%) received a single fraction protocol. The majority of patients (89, 60.1%) were referred to the radiation unit by their treating medical oncologists or hemato-oncologist. None of the patients were referred by palliative care team members at our center. Most (105, 70.9%) received previous systemic therapies; but less than half (48, 45.7%) were under active treatments within a month prior to the radiation simulation. CONCLUSION Relatively large number of patients with advanced malignancies are referred for futile palliative radiotherapy during the last 30 days of their life, thus impairing their quality of life and creating an unnecessary burden on public health services. These patients are often being referred by their treating oncologists who are familiar with their oncological history. These findings call for the implementation of collaborative multi-disciplinary teams, primarily directed at optimizing care at the end of life, setting achievable treatment goals, and improving quality of life.
