Summary
Gallbladder neuroendocrine neoplasms (GB-NENs) are highly malignant with a poor prognosis. This study highlights their characteristics and treatment, emphasizing the need for further research into management strategies.
Area of Science:
- Gastroenterology
- Oncology
- Pathology
Background:
- Gallbladder neuroendocrine neoplasms (GB-NENs) are rare and poorly understood.
- Real-world data on their clinicopathologic features and treatment is limited.
Purpose of the Study:
- To investigate the clinicopathologic characteristics of GB-NENs.
- To analyze the therapeutic situations and outcomes of GB-NENs.
Main Methods:
- A multicenter, large-scale cohort study involving 154 patients with GB-NENs.
- Retrospective analysis of clinicopathologic data and treatment approaches from 2004 to 2021.
Main Results:
- Most GB-NENs were poorly differentiated (62.3%) with a median age of 63 years; 61.7% were female.
- The liver was the most common metastatic site, and pre-operative diagnosis was 100% inaccurate.
- Overall survival rates were 59% at 1 year, 33% at 3 years, and 29% at 5 years.
Conclusions:
- GB-NENs exhibit high malignancy and poor prognosis.
- This study enhances understanding of GB-NENs, informing future research on mechanisms and treatment.
- Further investigation is crucial for optimizing GB-NEN management.
