Emergent high-dose radiotherapy followed by fractionated chemoradiation can be safely and effectively administered to critically ill, mechanically ventilated patients with cardiac angiosarcoma to relieve life-threatening tumor compression.
May support emergent RT feasibility in ventilated cardiac angiosarcoma; leaves open prospective validation before practice consideration.
BACKGROUND: Treating patients who are critically ill with radiotherapy (RT) brings a unique set of challenges as it involves treating patients who require mechanical life support, unconventional positioning, and a multidisciplinary team approach to ensure safety. However, when the benefits of such treatment outweigh the risks, the challenges can be overcome, as demonstrated in this unique case of cardiac angiosarcoma. CASE DESCRIPTION: This is a case of a 42-year-old female with a right sided cardiac angiosarcoma who quickly developed cardiac tamponade and respiratory failure related to compression of her right heart by the tumor. She was treated with high dose single fraction RT initially and had a clinical response allowing further conformal RT with concurrent chemotherapy. DISCUSSION: Managing critically ill patients requires creativity, improvisation, and careful consideration of existing evidence. Although limited, the data suggest that multi-modality therapy with a combination of surgery, RT, and chemotherapy provide the best outcomes.
