Front Oncol 2023; 12:1007317. [PMID: 36698410 PMCID: PMC9868580 DOI: 10.3389/fonc.2022.1007317] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2022] [Accepted: 12/08/2022] [Indexed: 01/11/2023] Open
Abstract
Background Mixed neuroendocrine non-neuroendocrine neoplasm (MiNEN) is an extremely rare entity, consisting of neuroendocrine and non-neuroendocrine components. It can occur in various organs throughout the body, with a rising incidence. Its clinical management is a rapidly growing field of interest; however, large-scale patient cohorts are still missing to guide clinical practice. Patients and methods The demographic, clinicopathological, and survival information of all patients diagnosed with MiNEN in the national Surveillance, Epidemiology, and End Results (SEER) program database (2000-2017) were extracted and further analyzed. The information of the patients before and after 2010 was compared to understand the epidemiological changes of MiNEN. The characteristics of MiNEN originating in different organs were compared. The clinical significance of surgical resection for metastatic MiNENs was also analyzed. Results A total of 1081 patients were screened, and after applying the exclusion criteria, 767 patients were finally analyzed. There was no obvious sex preference (49.2% vs 50.8%, p>0.05) and the majority of the patients were Caucasians (n=627, 81.7%). A total of 88.3% of the patients were older than 50 years old, and the median age was 60 years. 79.3% of the tumors are located in the distal digestive tract, and 67.7% were grade 3/4. Distant metastasis was presented in 33.9% of the patients at diagnosis. A total of 88% of the patients underwent surgical treatments. The number of patients increased 10-fold between 2000 and 2017. There was no significant difference in sex, race, stage, or surgical treatments among the patients diagnosed before and after 2010. More patients older than 60 years were diagnosed after 2010 (p=0.009). The median survival was 61.0 ± 9.8 months for the whole cohort. After multivariate analysis, older age (>60 years, p<0.01), more advanced stage (p<0.01), grade 3/4 (p<0.01), and non-surgical treatment (p<0.01) were independent risk factors for poorer survival. The appendiceal MiNENs showed the best prognosis. A total of 260 metastatic MiNENs were further analyzed. Only patients with metastatic MiNENs originating from the appendix had a potential benefit from surgical resection, compared to other sites (p=0.05). Conclusion This study provides the epidemiological, clinicopathological, and survival information of the largest number of MiNEN patients. Although MiNEN is an extremely rare malignant neoplasm, its incidence increases rapidly. The majority of the patients suffered from advanced-stage disease, which highlights the need for improvement of early detection in the future. The appendix is the most common primary site of MiNEN, and surgical resection for selected metastatic MiNEN originating in the appendix has favorable survival outcomes.

Ling C, Hong X, Xu M, Wang Y, Ma X, Cui Y, Jiang R, Cao D, Wu H, Tong A, Zhao Y, Wu W. Convergence between germline and somatic mutations in pancreatic neuroendocrine tumors. Eur J Endocrinol 2022; 187:85-90. [PMID: 35521758 DOI: 10.1530/eje-21-0893] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/27/2021] [Accepted: 04/25/2022] [Indexed: 11/08/2022]
Abstract
OBJECTIVES The pancreatic neuroendocrine tumors (PanNETs) are a group of clinically heterogeneous neoplasms. Although previous studies illustrated the somatic mutation pattern for PanNETs, the germline mutation pattern is still unclear. Here, we comprehensively screened the underlying germline mutations in a cohort of multiple endocrine neoplasia type 1 (MEN1)-related and sporadic PanNETs to reveal the characteristics of germline mutation in PanNET patients. METHODS Patients diagnosed with PanNETs by biopsy or surgical pathology were enrolled in this study. Peripheral blood samples were used for genomic DNA purification and subsequent sequencing. The following sequencing techniques were used and compared for validation: (1) targeted gene capture with a customized panel; (2) whole exome sequencing data from previous study. RESULTS A total of 184 PanNET patients were enrolled, including 20 MEN1-related and 164 sporadic cases. In this study, MEN1 mutation rate in MEN1-related PanNETs was 60% (12/20), of which 50% were novel mutation sites. For sporadic PanNETs, the overall germline mutation rate was very low. Besides the rare MEN1 mutation, previously unreported germline variant in DAXX was found in one non-functional PanNET. CONCLUSIONS This study revealed distinctive germline mutation rates between MEN1-related and sporadic PanNETs. The novel MEN1 mutations contribute to revealing the spectrum of MEN1 mutations in PanNETs. The newly discovered germline variant of DAXX in sporadic PanNET implies a tendency of convergence between germline and somatic mutation genes.

Abstract
According to the 2019 WHO pathology grading system, high-grade gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs) can be divided into well differentiated neuroendocrine tumors G3 (NETs G3) and poorly differentiated neuroendocrine carcinomas (NECs). GEP-NETs G3 and GEP-NECs present significant differences in driver genes and disease origin. NETs G3 and NECs have been confirmed to be two distinct diseases with different genetic backgrounds, however, this issue remains controversial. The prognosis of NETs G3 is significantly better than that of NECs. The differential diagnosis of GEP-NETs G3 and GEP-NECs should be combined with the patient's medical history, tumor histopathology, Ki-67 index, DAXX/ATRX, TP53 and Rb expression as well as other immunohistochemical indicators. In addition, the treatment strategies of these two subgroups are very different. Here, we summarize recent findings focused on the genomics, clinical manifestations, diagnosis, treatment and other aspects of high-grade GEP-NENs (G3). This review may help further our understanding of the carcinogenesis, diagnosis and treatment of GEP-NENs G3.
