Rapid Clinical Updates: How We Approach Oncologic Emergencies: A Framework for the Hospitalist-Handout

Pdf Summary

The document presents a practical framework for hospitalists to recognize and manage oncologic emergencies, emphasizing that presentations can be highly variable and rapidly life-threatening. It highlights the importance of using a structured approach, identifying key clinical scenarios, and involving oncology and other subspecialists early.

Major emergencies discussed include:

- <strong>Hypercalcemia of malignancy:</strong> Commonly caused by humoral mechanisms, with other causes including osteolytic disease, calcitriol-mediated hypercalcemia, and rare ectopic PTH secretion. Recommended workup includes PTH, PTHrP, 1,25-OH vitamin D, and SPEP/UPEP. Treatment centers on IV fluids, calcitonin for rapid effect, bisphosphonates for longer-term control, denosumab for refractory cases or renal failure, and glucocorticoids for vitamin D–mediated cases.

- <strong>Immune checkpoint inhibitor-related toxicities (irAEs):</strong> These can affect nearly any organ system and may present as subtle or severe inflammation (“itis” in any organ). Because of their complexity and potential danger, subspecialist involvement is essential.

- <strong>Visceral crisis:</strong> A state of severe organ dysfunction, especially seen in breast cancer. Examples include lung crisis with rapidly worsening dyspnea not relieved by effusion drainage, and liver crisis with a rapid bilirubin rise without biliary obstruction. Management requires multidisciplinary discussion, consideration of systemic therapy, and careful risk-benefit/prognosis assessment.

- <strong>Cord compression:</strong> Often missed, with warning signs such as pain, motor or sensory deficits, decreased rectal tone, saddle anesthesia, and increased reflexes. Diagnosis requires MRI of the full spine with and without gadolinium. Treatment is multidisciplinary, involving surgery, radiation, and sometimes systemic therapy.

The document also notes other urgent situations where time is critical, including small cell lung cancer, anaplastic thyroid cancer, tumor lysis, major organ failure, and lymphoma/leukemia.
