Comparison of the clinical features and long-term prognosis of gallbladder neuroendocrine carcinoma versus gallbladder adenocarcinoma: A propensity score-matched analysis. BIOMOLECULES & BIOMEDICINE 2023; 23:1096-1107. [PMID: 37724922 PMCID: PMC10655887 DOI: 10.17305/bb.2023.9582] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/28/2023] [Revised: 09/07/2023] [Accepted: 09/07/2023] [Indexed: 09/21/2023]
Abstract
Gallbladder neuroendocrine carcinoma (GBNEC) is rare and characterized by a low degree of tumor differentiation. The clinical features of GBNEC versus gallbladder adenocarcinoma (GBADC) remain a subject of debate. A total of 201 GBADC and 36 GBNEC cases that underwent surgery resection between January 2010 and 2022 at the Department of Biliary Surgery, West China Hospital, Sichuan University were included. A 1:1 propensity score matching (PSM) was performed based on seven predefined variables: age, sex, the American Joint Committee on Cancer (AJCC) stage, resection status, perineural invasion (PNI), lymphovascular invasion (LVI), and degree of tumor differentiation. Compared with GBADC, GBNEC patients were younger (median age 56.0 vs 64.0 years; P = 0.001), and more patients presented with advanced stages of tumor (P = 0.003). Patients with GBNEC also had a higher rate of PNI (55.6% vs 22.4%; P < 0.001), and LVI (63.9% vs 45.80%; P = 0.658). Before PSM, GBNEC patients had inferior prognoses compared with GBADC patients with a shorter median overall survival (mOS) (15.02 vs 20.11 months; P = 0.0028) and a shorter median recurrence-free survival (mRFS) (10.30 vs 15.17 months; P = 0.0028). However, after PSM analyses, there were no differences in OS (mOS 18.6 vs 18.0 months; P=0.24) or RFS (mRFS 10.98 vs 12.02 months; P = 0.39) between the GBNEC and GBADC cases. After multivariate analysis, tumor diagnosis (GBNEC vs GBADC) was not identified as an independent risk factor for shorter RFS (P = 0.506) or OS (P = 0.731). Unfavorable pathological features, including advanced AJCC tumor stages, poor differentiation, presence of LVI, and positive resection margins (all P < 0.05), were independent risk factors for inferior OS and RFS. GBNEC is difficult to diagnose early and has a prognosis comparable to stage-matched poorly differentiated GBADC. Tumor diagnosis (either GBADC or GBNEC) was not an independent risk factor for the patient's OS. Unfavorable pathological features of the neoplasm are the main determinants.

[PMID: 37432551 DOI: 10.1007/s12325-023-02597-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2023] [Accepted: 06/26/2023] [Indexed: 07/12/2023]
Abstract
INTRODUCTION This study was performed to evaluate the prognostic value of the neuroendocrine component in patients with extrahepatic cholangiocarcinoma (EHCC). METHODS Cases with EHCC derived from the SEER database were retrospectively reviewed and analyzed. The clinicopathological features and long-term survival were compared between patients with neuroendocrine carcinoma (NECA) and those with pure adenocarcinoma (AC). RESULTS A total of 3277 patients with EHCC were included (62 patients with NECA and 3215 patients with AC). T stage (P = 0.531) and M stage (P = 0.269) were comparable between the two groups. However, lymph node metastasis was more frequently detected in NECA (P = 0.022). NECA was correlated with more advanced tumor stage than pure AC (P < 0.0001). Inconsistent differentiation status was also observed between the two groups (P = 0.001). The proportion of patients who received surgery was significantly higher in the NECA group (80.6% vs 62.0%, P = 0.003) while chemotherapy was more frequently performed among patients with pure AC (45.7% vs 25.8%, P = 0.002). Comparable incidence of radiotherapy was acquired (P = 0.117). Patients with NECA shared a better overall survival than those with pure AC (P = 0.0141), even after matching (P = 0.0366). The results of univariate and multivariate analyses indicated that the neuroendocrine component was a protective factor as well as an independent prognostic factor for overall survival (HR < 1, P < 0.05). CONCLUSION Patients with EHCC with a neuroendocrine component shared a better prognosis than those with pure AC, and NECA could serve as a favorable prognostic factor for overall survival. Considering various unprovided but potentially confounding factors, future more well-conducted research is required.

A prognostic nomogram based on log odds of positive lymph nodes to predict the overall survival in biliary neuroendocrine neoplasms (NENs) patients after surgery. J Endocrinol Invest 2022; 45:2341-2351. [PMID: 35908009 DOI: 10.1007/s40618-022-01874-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/24/2022] [Accepted: 07/17/2022] [Indexed: 10/16/2022]
Abstract
BACKGROUND The prognosis of biliary neuroendocrine neoplasms (NENs) patients is affected by the status of metastatic lymph nodes. The purpose of this study was to explore the prognostic value of the log odds of positive lymph nodes (LODDS) and develop a novel nomogram to predict the overall survival (OS) in biliary NENs patients. METHODS A total of 125 patients with histologically confirmed biliary NENs were selected from the Surveillance, Epidemiology and End Results (SEER) database and further divided into training and validation cohorts. The discrimination and calibration of the nomogram were evaluated using the concordance index (C-index), the area under the time-dependent receiver operating characteristic curve (time-dependent AUC), and calibration plots. The net benefits and clinical utility of the nomogram were quantified and compared with those of the SEER staging system using decision curve analysis (DCA), net reclassification index (NRI), and integrated discrimination improvement (IDI). The risk stratifications of the nomogram and the SEER staging system were compared. RESULTS LODDS showed the highest accuracy in predicting OS for biliary NENs. The C-index (0.789 for the training cohort and 0.890 for the validation cohort) and the time-dependent AUC (> 0.7) indicated the satisfactory discriminative ability of the nomogram. The calibration plots showed a high degree of consistency. The DCA, NRI, and IDI indicated that the nomogram performed significantly better than the SEER staging system. CONCLUSION A novel LODDS-incorporated nomogram was developed and validated to assist clinicians in evaluating the prognosis of biliary NENs patients.
