Походження тривожної ознаки
| Визначення | Active carcinoid syndrome in a patient with metastatic or unresectable GI-NET (or other serotonin-secreting NET). Defined clinically by any of: episodic flushing, secretory diarrhea (≥4 loose stools/day), bronchoconstriction, or elevated 24h urinary 5-HIAA / serum serotonin. Carcinoid syndrome mandates SSA therapy for symptom control regardless of antiproliferative intent; SSA is also the antiproliferative standard (CLARINET, PROMID). |

Reverted to draft: true pending second source (SRC-ESMO-NET-2024 or similar) per §6.1 two-reviewer quality gate. Currently only cites SRC-NCCN-NET-2025. Carcinoid syndrome hallmarks: episodic cutaneous flushing (serotonin + bradykinin), diarrhea (serotonin, prostaglandins), bronchoconstriction, carcinoid heart disease (Hedinger syndrome — right-sided valvular fibrosis from chronic serotonin exposure). Biochemical confirmation: 24h urinary 5-HIAA >50 µmol/day (normal: <30). SSA reduces 5-HIAA ~50% and controls symptoms in ~70% initially. SSA dose escalation (octreotide short-acting rescue; lanreotide dose increase) and addition of telotristat ethyl (tryptophan hydroxylase inhibitor) for refractory diarrhea. Carcinoid crisis risk during surgery / embolisation — SSA IV cover required. Carcinoid heart disease: echocardiogram at baseline + annually; surgery for severe tricuspid/pulmonary regurgitation if fit.
