Neuroendocrine neoplasm (NEN) of the gallbladder is rare. It is usually asymptomatic and occurs in older adults. Its clinicopathological characteristics remain controversial, and the diagnosis and tre...
The data of patients with gallbladder NEN admitted to Peking Union Medical College Hospital was reviewed, and a database was established for retrospective analysis. Clinicopathological features were a...
In total, 22 patients with gallbladder NEN were included in this study. There were 10 male (45.5%) and 12 female (54.5%) patients with a median age of onset of NEN at 57.5 (49.0, 62.3) years. Abdomina...
Gallbladder NEN is more common in the elderly and has a slight female predominance. The most common symptom is abdominal discomfort. Surgery is the first choice of treatment for this rare disease. The...
Mixed neuroendocrine-non-neuroendocrine neoplasms (MiNENs) of the gallbladder are rare malignancies. Here we presented two cases and reviewed the related literature....
Our two patients were postoperatively diagnosed with gallbladder MiNENs, which pathologically consisted of a large cell neuroendocrine carcinoma and papillary adenocarcinoma. After cholecystectomy, on...
Our two cases and the cases in the literature suggest that MiNENs of the gallbladder predominantly occur in women; are associated with early lymph node metastasis, local hepatic invasion, and hepatic ...
Intracholecystic papillary neoplasm (ICPN) is a non-invasive epithelial tumor that presents as a grossly identifiable mass arising in the mucosa and protruding into the lumen. ICPN is associated with ...
This study aimed to comprehensively investigate the clinicopathologic characteristics and therapeutic situations of gallbladder neuroendocrine neoplasms (GB-NENs) in the real world via a multicenter, ...
The study searched for patients in 143 hospitals in China and enrolled 154 patients with GB-NENs diagnosed in 40 hospitals between 2004 and 2021. Clinicopathologic characteristics and therapeutic appr...
