Carcinoid Crisis: A Misunderstood and Unrecognized Oncological Emergency

Area of Science:

• Oncology
• Endocrinology
• Critical Care Medicine

Background:

• Carcinoid Crisis is a rare, life-threatening complication of neuroendocrine tumors (NETs).
• It manifests as sudden hemodynamic instability, potentially with carcinoid syndrome symptoms like bronchospasm and flushing.
• Caused by a massive release of vasoactive substances from neuroendocrine cells, it can occur post-procedure or spontaneously.

Purpose of the Study:

• To review the current understanding and management of Carcinoid Crisis in NET patients.
• To highlight the lack of established clinical guidelines for this oncologic emergency.
• To emphasize the critical role of preventive strategies.

Main Methods:

• Review of existing literature, including case reports and small retrospective series.
• Analysis of the pathophysiology and clinical presentation of Carcinoid Crisis.
• Evaluation of current prophylactic and acute management approaches.

Main Results:

• Carcinoid Crisis presents with severe hypotension unresponsive to standard treatments, often requiring Intensive Care Unit transfer.
• No evidence-based guidelines exist for managing this condition.
• Preventive measures, including octreotide, anxiolytics, and antihistamines, are the primary strategy to avoid complications.

Conclusions:

• Carcinoid Crisis is a critical medical emergency in NET patients with no established treatment protocols.
• Prevention through targeted pharmacological interventions is the most effective approach.
• Further research is needed to develop standardized management guidelines for this rare but dangerous condition.
