Neuroendocrine Tumors

Research on neuroendocrine tumors (NETs) including carcinoid tumors, pancreatic NETs, and gastroenteropancreatic NETs. Studies evaluate tumor control, symptom management, and survival outcomes.

Detailed Outcomes

|
A
Tumor Progression (NETs)
PROMID trial showed median time to tumor progression of 14.3 months vs 6 months placebo (HR 0.34, P<0.001) in metastatic midgut NETs.
large↓Improves
A
Carcinoid Syndrome Symptoms
Over 70% of patients achieve significant improvement or resolution of diarrhea and flushing with octreotide LAR treatment.
large↓Improves
A
VIPoma Diarrhea
FDA-approved for watery diarrhea associated with VIP-secreting tumors, with significant symptom improvement.
large↓Improves
B
Survival (NETs)
Retrospective data suggest improved 5-year survival (67% vs 18% historical controls) in advanced GEP-NETs treated with octreotide.
moderate↑Improves
A
Progression-Free Survival
NETTER-1: 65.2% PFS rate at month 20 vs 10.8% control. 79% reduction in progression/death risk. Median PFS not reached vs ~8 months control. Doubled median PFS from 9 to 23 months in GEP-NETs.
large↑Improves
A
Overall Survival
Final NETTER-1: Median OS 48.0 months vs 36.3 months control (11.7 month benefit). HR 0.84. Clinically meaningful survival advantage despite P=0.30 due to crossover.

A
Objective Response Rate
NETTER-1: Significantly higher ORR with 177Lu-DOTATATE vs control. 16% ORR including complete responses in ERASMUS study subset. Tumor shrinkage correlates with improved outcomes.
large↑Improves
A
Quality of Life
Time to QoL deterioration: 28.8 months vs 6.1 months (global health). Physical functioning: 25.2 months vs 11.5 months. Clinically significant improvements maintained long-term.

A
Progression-Free Survival (NETs)
CLARINET trial: 53% reduction in disease progression risk (HR 0.47, P<0.001). 65.1% vs 33.0% PFS at 24 months. Median PFS not reached vs 18 months placebo.
large↑Improves
A
Tumor Stabilization (NETs)
Stable disease rates of 15-89% in clinical trials. Phase II studies show significant antitumor effects with disease control in majority of patients.
large↑Improves
A
Carcinoid Syndrome Symptoms
FDA-approved for symptomatic control of flushing and diarrhea associated with carcinoid syndrome. Significant QOL improvement in symptomatic patients.
large↓Improves
A
VIPoma Symptoms
Effective for controlling watery diarrhea and electrolyte disturbances in VIP-secreting tumors.
