Emerging Therapeutic Concepts and Latest Diagnostic Advancements Regarding Neuroendocrine Tumors of the Gynecologic Tract. MEDICINA (KAUNAS, LITHUANIA) 2021; 57:medicina57121338. [PMID: 34946283 PMCID: PMC8703600 DOI: 10.3390/medicina57121338] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 11/04/2021] [Revised: 11/29/2021] [Accepted: 12/02/2021] [Indexed: 12/21/2022]
Abstract
Neuroendocrine neoplasms (NENs) are particularly rare in all sites of the gynecological tract and include a variety of neoplasms with variable prognosis, dependent on histologic subtype and site of origin. Following the expert consensus proposal of the International Agency for Research on Cancer (IARC), the approach in the latest World Health Organization (WHO) Classification System of the Female Genital Tumours is to use the same terminology for NENs at all body sites. The main concept of this novel classification framework is to align it to all other body sites and make a clear distinction between well-differentiated neuroendocrine tumors (NETs) and poorly differentiated neuroendocrine carcinomas (NECs). The previous WHO Classification System of the Female Genital Tumours featured more or less the same principle, but used the terms ‘low-grade neuroendocrine tumor’ and ‘high-grade neuroendocrine carcinoma’. Regardless of the terminology used, each of these two main categories include two distinct morphological subtypes: NETs are represented by typical and atypical carcinoid and NEC are represented by small cell neuroendocrine carcinoma (SCNEC) and large cell neuroendocrine carcinoma (LCNEC). High-grade NECs, especially small cell neuroendocrine carcinoma tends to be more frequent in the uterine cervix, followed by the endometrium, while low-grade NETs usually occur in the ovary. NENs of the vulva, vagina and fallopian tube are exceptionally rare, with scattered case reports in the scientific literature.

Abstract
Neuroendocrine tumors (NETs) are a heterogeneous clinical entity with a broad range of grade, pace of disease, functional status, and primary sites. Pathologic classification, diagnostic modalities, and therapeutic options for NETs have evolved considerably in the past decade. In part driven by these advances, incidence and prevalence of NETs are rising in the United States and the practicing oncologist is likely to encounter these in the clinic. However, there are no clear lines of therapy for unresectable or metastatic NETs, and sequencing of systemic therapies depends on consideration of patient and tumor characteristics including extent of disease, grade, pace of growth, functional status, primary site, somatostatin receptor status, performance status, and comorbidities. Familiarity with ongoing clinical trials will guide therapeutic decision making as well. In this review, we seek to provide a framework to formulate and tailor an individualized treatment plan for each patient with a NET.

Non-Pharmacological Therapeutic Options for Liver Metastases in Advanced Neuroendocrine Tumors. J Clin Med 2019; 8:jcm8111907. [PMID: 31703375 PMCID: PMC6912565 DOI: 10.3390/jcm8111907] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2019] [Revised: 10/29/2019] [Accepted: 11/05/2019] [Indexed: 12/18/2022] Open
Abstract
The incidence of liver metastasis in digestive neuroendocrine tumors is high. Their presence appears as an important prognostic factor in terms of quality of life and survival. These tumors may be symptomatic because of the tumor burden itself and/or the hormonal hyper-secretion induced by the tumor. Surgery is the treatment of choice for resectable tumors and metastasis. Nevertheless, surgery is only possible in a small number of cases. The management of non-resectable liver metastasis is a challenge. The literature is rich but consists predominantly in small retrospective series with a low level of proof. Thus, the choice of one technique over another could be difficult. Local ablative techniques (radiofrequency) or trans-catheter intra-arterial liver-directed treatments (hepatic artery embolization, chemo-embolization, and radio-embolization) are frequently considered for liver metastasis. In the present review, we focus on these different therapeutic approaches in advanced neuroendocrine tumors, results (clinical and radiological), and overall efficacy, and summarize recommendations to help physicians in their clinical practice.

Abstract
Uterine cervix carcinoids are distinct neuroendocrine cervical tumors, representing a comparatively small percentage of them. These well-differentiated neoplasms are far less prevalent than small- and large-cell carcinomas, characterized by a more favorable biological course. We report a case of a 43-year-old woman with a nonmetastatic cervical carcinoid, managed with radical hysterectomy. She still remains free of disease. Scant reports in the literature prohibit any reliable prediction of cervical carcinoid prognosis. Thus, prompt identification of the disease and subsequent therapeutic intervention could alter the final outcome.

Abstract
OBJECTIVES To compare efficacy, survival outcome and prognostic factors of conventional transarterial chemoembolisation (cTACE), drug-eluting beads TACE (DEB-TACE) and yttrium-90 radioembolisation (Y90) for the treatment of liver metastases from gastroenteropancreatic (GEP) neuroendocrine tumours (NELM). METHODS This retrospective analysis included 192 patients (58.6 years mean age, 56% men) with NELM treated with cTACE (N = 122), DEB-TACE (N = 26) or Y90 (N = 44) between 2000 and 2014. Radiologic response to therapy was assessed according to Response Evaluation Criteria in Solid Tumours (RECIST) and World Health Organization (WHO) criteria using periprocedural MR imaging. Survival analysis included propensity score analysis (PSA), median overall survival (MOS), hepatic progression-free survival, Kaplan-Meier using log-rank test and the uni- and multivariate Cox proportional hazards model (MVA). RESULTS MOS of the entire study population was 28.8 months. As for cTACE, DEB-TACE and Y90, MOS was 33.8 months, 21.7 months and 23.6 months, respectively. According to the MVA, cTACE demonstrated a significantly longer MOS as compared to DEB-TACE (p <.01) or Y90 (p = .02). The 5-year survival rate after initial cTACE, DEB-TACE and Y90 was 28.2%, 10.3% and 18.5%, respectively. CONCLUSIONS Upon PSA, our study suggests significant survival benefits for patients treated with cTACE as compared to DEB-TACE and Y90. This data supports the therapeutic decision for cTACE as the primary intra-arterial therapy option in patients with unresectable NELM until proven otherwise. KEY POINTS • cTACE achieved a significantly longer overall survival in patients with unresectable NELM. • Patients treated with cTACE showed a prolonged hepatic progression-free survival. • cTACE, DEB-TACE and Y90 radioembolisation demonstrated comparable safety and toxicity profiles. • Age >70 years, extrahepatic metastases and tumour burden >50% were identified as negative predictors. • Propensity score analysis suggests the superiority of cTACE over DEB-TACE and Y90.

Abstract
Gastrin-independent gastric neuroendocrine tumors (GNETs) are highly malignant. Radical resections and lymphadenectomy are considered to be the only possible curative treatment for these tumors. However, the prognosis of gastrin-independent GNETs is not well defined. In this study, we identified prognostic factors of locoregional gastrin-independent GNETs.All patients diagnosed with locoregional gastrin-independent GNETs between 2000 and 2014 were included in this retrospective study. Clinical characteristics, blood tests, pathological characteristics, treatments, and follow-up data of the patients were collected and analyzed.Of the 66 patients diagnosed with locoregional gastrin-independent GNETs, 57 (86.4%) received radical resections, 7 (10.6%) with palliative resection, 1 (1.5%) with gastrojejunostomy, and 1 (1.5%) with exploration surgeries. The median survival time for these patients was 19.0 months (interquartile range, 11.0-38.0). The 1-, 3-, and 5-year survival rates were 72%, 34%, and 28%, respectively. Multivariate analysis indicated that carcinoembryonic antigen (CEA) level (P = 0.04), radical resection (P = 0.04), and positive Cluster of Differentiation 56 (CD56) expression (P = 0.016) were significant prognostic factors on overall survival rate. Further univariate and multivariate analysis of 57 patients who received radical resections found that CgA expression (P = 0.35) and CEA level (P = 0.33) are independent prognostic factors.Gastrin-independent GNETs had poor prognosis. Serum CEA level, radical surgery, CD56 and CgA expression are markers to evaluate the survival of patients with locoregional gastrin-independent GNETs.

Abstract
Lung cancer encompasses a diverse spectrum of histologic subtypes. Until recently, the majority of therapeutic advances were limited to the minority of patients with adenocarcinoma. With the advent of comprehensive genomic profiling of squamous and small cell lung cancers, new therapeutic targets have emerged. For squamous tumors, the most promising of these include fibroblast growth factor receptor (FGFR), the phosphatidylinositol 3-kinase (PI3K) pathway, discoidin domain receptor 2 (DDR2), and G1/S checkpoint regulators. In 2014, the antiangiogenic agent ramucirumab was approved for all non-small cell lung cancer (NSCLC) histologies, including squamous tumors. Immunotherapeutic approaches also appear to be promising for these cases. Genomic analysis of small cell lung cancer has revealed a high mutation burden, but relatively few druggable driver oncogenic alterations. Current treatment strategies under investigation are focusing on targeting mitotic, cell cycle, and DNA repair regulation, as well as immunotherapy. Pulmonary neuroendocrine tumors represent a diverse spectrum of diseases that may be treated with somatostatin analogs, cytotoxic agents, and molecularly targeted therapies. Radiolabeled somatostatin analogs and combinations with mammalian target of rapamycin (mTOR) inhibitors also show potential. Large cell neuroendocrine tumors share numerous clinical, pathologic, and molecular features with small cell lung cancer; however, whether they should be treated similarly or according to a NSCLC paradigm remains a matter of debate.

Abstract
Hepatic metastases, which are frequently seen in patients with neuroendocrine tumors (NETs), have a major adverse impact on the patient's quality of life and survival. Surgery is the treatment of choice for hepatic metastases but is possible in only a small percentage of patients. Systemic chemotherapy yields disappointing results. Somatostatin analogs are effective in controlling symptoms in many of these patients; however, the disease can become refractory to treatment. Transcatheter intra-arterial liver-directed therapies, such as hepatic artery embolization, chemoembolization, and radioembolization are frequently used in patients with NETs metastatic to the liver, especially in patients with refractory, unresectable, or recurrent disease. These treatments are effective in palliating the hormonal symptoms as well as achieving objective tumor responses. This review focuses on the technique, safety, and clinical efficacy of hepatic artery embolization, chemoembolization, and radioembolization in patients with metastatic NETs.

Abstract
AIM: To describe our patients affected with ectopic biliary tree gastrinoma and review the literature on this topic.
METHODS: Between January 1992 and June 2012, 28 patients affected by duodenopancreatic endocrine tumors in multiple endocrine neoplasia type 1 (MEN1) syndrome underwent surgery at our institution. This retrospective review article analyzes our experience regarding seventeen of these patients subjected to duodenopancreatic surgery for Zollinger-Ellison syndrome (ZES). Surgical treatment consisted of duodenopancreatectomy (DP) or total pancreatectomy (TP). Regional lymphadenectomy was always performed. Any hepatic tumoral lesions found were removed during surgery. In MEN1 patients, removal of duodenal lesions can sometimes lead to persistence or recurrence of hypergastrinemia. One possible explanation for this unfavorable outcome could be unrecognized ectopic localization of gastrin-secreting tumors. This study described three cases among the seventeen patients who were found to have an ectopic gastrinoma located in the biliary tree.
RESULTS: Seventeen MEN1 patients affected with ZES were analyzed. The mean age was 40 years. Fifteen patients underwent DP and two TP. On histopathological examination, duodeno pancreatic endocrine tumors were found in all 17 patients. Eighty-one gastrinomas were detected in the first three portions of the duodenum. Only one gastrinoma was found in the pancreas. The mean number of gastrinomas per patient was 5 (range 1-16). Malignancy was established in 12 patients (70.5%) after lymph node, liver and omental metastases were found. Three patients exhibited biliary tree gastrinomas as well as duodenal gastrinoma(s). In two cases, the ectopic gastrinoma was removed at the same time as pancreatic surgery, while in the third case, the biliary tree gastrinoma was resected one year after DP because of recurrence of ZES.
CONCLUSION: These findings suggest the importance of checking for the presence of ectopic gastrinomas in the biliary tree in MEN1 patients undergoing ZES surgery.

Abstract
OBJECTIVE Neuroendocrine tumors of the gynecologic tract are rare, and pose a significant clinical challenge because of the tumor heterogeneity and lack of standardized guidelines for treatment. This manuscript summarizes the available literature concerning these tumors in an effort to provide the clinician a framework from which to guide patient management. METHODS MEDLINE was searched for all research articles published in English between January 1, 1966 and March 1, 2011 in which the studied population included women diagnosed with neuroendocrine tumors of the gynecologic tract. Although preference was given to prospective studies, studies were not limited by design or by numbers of subjects given the limited availability of reports. RESULTS Most, but not all, neuroendocrine tumors of the gynecologic tract have an aggressive clinical course and those of the cervix histologically and clinically share similarities with small cell lung cancer. Cumulative data supports a multi-modality therapeutic strategy. A proposed management algorithm for neuroendocrine carcinomas of the cervix is outlined. For less frequent disease sites including the adnexa, uterus, vagina and vulva, as well as well differentiated carcinoid tumors, surgical resection is appropriate in selected cases. Etoposide/platinum based chemotherapy is used for neuroendocrine carcinomas but not for well differentiated carcinoid tumors. Well differentiated carcinoid and atypical carcinoid tumors should be managed similar to gastroenteropancreatic NETs (GEP-NETs). CONCLUSIONS Most neuroendocrine tumors of the gynecologic tract require a multi-modality therapeutic approach, determined by extent of disease and primary organ of involvement. Pathologic diagnosis is critical to guide therapy.

Abstract
Neuroendocrine tumors (NETs) comprise a diverse group of slowly growing tumors with an indolent course, characterized by the capacity to synthesize and secrete polypeptide products that are hormonally active. Presence of liver metastases results in significant debilitating hormonal symptoms, and is associated with poor prognosis. Systemic chemotherapy has limited success in the management of patients with NET hepatic metastases. Although somatostatin analogs are effective in controlling symptoms in many of these patients, the disease can become refractory to treatment. For these reasons, interventional radiologic techniques for liver-directed therapy have become an important treatment option in patients with metastatic NETs. Transcatheter arterial procedures such as transarterial embolization (TAE), transarterial chemoembolization (TACE), and selective internal radiation therapy (SIRT) have been shown to reduce hormone levels, palliate symptoms, and reduce the tumor burden in many patients with unresectable and symptomatic NET hepatic metastases. This article summarizes the most recent information on arterial-based liver-directed therapies in the treatment of metastatic NETs.
