Zeng F, Guo P, Xia M, He M. Total hysterectomy versus radical hysterectomy in neuroendocrine cervical cancer: a SEER-database analysis. J Cancer Res Clin Oncol 2024; 150:236. [PMID: 38710946 PMCID: PMC11074048 DOI: 10.1007/s00432-024-05773-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/29/2024] [Accepted: 04/30/2024] [Indexed: 05/08/2024]
Abstract
PURPOSE We conducted this study to evaluate the efficacy of total hysterectomy versus radical hysterectomy in the treatment of neuroendocrine cervical cancer (NECC). METHODS Eligible NECC patients were identified from the Surveillance, Epidemiology and End Results (SEER) database. Demographic characteristics, clinical treatment and survival of the patients were collected. The overall survival (OS) and cancer-specific survival (CSS) were estimated by Kaplan-Meier analysis with log-rank test. RESULTS A total of 286 patients were included, with 104 patients undergoing total hysterectomy and 182 patients undergoing radical hysterectomy. The 5-year OS were 50.8% in the total hysterectomy group and 47.5% in the radical hysterectomy group (p = 0.450); and the corresponding 5-year CSS were 51.6% and 49.1% (p = 0.494), respectively. Along with surgery, radiotherapy was given to 49.0% of patients in the total hysterectomy group and 50.5% in the radical hysterectomy group; and chemotherapy was administered to 77.9% of patients in the total hysterectomy group and 85.7% in the radical hysterectomy group. Unexpectedly, in patients who received adjuvant radiotherapy with or without chemotherapy, the OS was superior in the total hysterectomy group compared with the radical hysterectomy group (p = 0.034). While in patients who received chemotherapy alone and those who received neither radiotherapy nor chemotherapy, the OS still remained comparable between the total hysterectomy and radical hysterectomy group. CONCLUSION Compared with radical hysterectomy, total hysterectomy was not associated with compromised survival prognosis in patients with NECC. Total hysterectomy has the potential to be a surgical alternative in the multimodal management of NECC.

Asa SL, Ezzat S. Endocrine tumors of the female reproductive tract. Mol Cell Endocrinol 2024; 582:112123. [PMID: 38135144 DOI: 10.1016/j.mce.2023.112123] [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: 09/18/2023] [Revised: 12/08/2023] [Accepted: 12/09/2023] [Indexed: 12/24/2023]
Abstract
Endocrine cells responsible for hormone secretion are found in virtually every organ system. The diverse neoplasms arising from endocrine cells in the female reproductive tract are not well recognized as a distinct component of endocrine oncology. Here, we integrate cellular origins with native anatomical residence to help classify neoplasms of this system. The neoplasms include steroidogenic tumors that arise usually in ovarian stroma, neuroendocrine neoplasms that can arise from normal neuroendocrine cells throughout the female reproductive tract or in ovarian germ cell tumors, and thyroid follicular cell proliferations that are exclusively a component of an ovarian teratoma and may be malignant. The neuroendocrine neoplasms run the full spectrum from indolent neuroendocrine tumors to aggressive poorly differentiated neuroendocrine carcinomas. While many of these lesions are identified as incidental findings in surgically resected tissues, others present with inappropriate hormone excess. An important consideration is the distinction of primary disease from metastatic malignancy. Genetic disorders including those caused by germline mutations of the FOXL2, GNAS, DICER1, STK11 and MEN1 genes can present with primary endocrine neoplasms of the female reproductive tract.

Abstract
AIM There is no conclusive data on the prognosis of patients who receive paclitaxel-carboplatin (TC) plus bevacizumab therapy for advanced neuroendocrine carcinoma (NEC) of the uterine cervix, a rare histological subtype of cervical cancer. Thus, the aim of this study was to determine the efficacy of TC chemotherapy plus bevacizumab and bevacizumab single maintenance therapy for advanced NEC of the cervix. METHODS This was a retrospective review of patients who received TC plus bevacizumab therapy for metastatic, recurrent, or persistent NEC of the cervix at seven institutions between 2015 and 2020. Relevant data were extracted from the patients' medical records and analyzed. RESULTS Seven patients, including six with small-cell NEC and one with large-cell NEC, were included for analysis. Three patients received bevacizumab single maintenance therapy following TC plus bevacizumab therapy, whereas four patients did not receive bevacizumab single maintenance therapy. The median overall survival and progression-free survival of the patients who received bevacizumab single maintenance therapy were longer than those of the patients who did not receive the therapy (34 months vs. 10.5 months and 19 months vs. 5 months, respectively). However, the patients who received bevacizumab single maintenance therapy had received cisplatin-based chemotherapy previously. CONCLUSIONS On the premise that cisplatin-based chemotherapy is administered as the first-line treatment for advanced NEC of the cervix, bevacizumab single maintenance therapy following TC plus bevacizumab may be considered the second- or third-line treatment. However, the risk of adverse events, such as intestinal perforation, should be discussed with patients.

Abstract
Neuroendocrine neoplasms (NENs) were classified separately in the 5th edition (2020) of the World Health Organization (WHO) classification of female genital malignancies. Cervical neuroendocrine carcinoma (NEC) is distinguished by its low incidence, high invasiveness, early local dissemination, and distant metastases. The purpose of this review is to outline the achievements in pathology, diagnostics, gene sequencing, and multi-modality treatment of cervical NEC.

Abstract
The aim of the current study is to investigate the survival outcome of stage IVB SCNEC of the uterine cervix in comparison to major histological subtypes of cervical cancer. A population-based retrospective cohort study was conducted using the Osaka Cancer Registry data from 1994 to 2018. All FIGO 2009 stage IVB cervical cancer patients who displayed squamous cell carcinoma (SCC), adenocarcinoma (A), adenosquamous cell carcinoma (AS), or small-cell neuroendocrine carcinoma (SCNEC) were first identified. The patients were classified into groups according to the types of primary treatment. Then, their survival rates were examined using the Kaplan-Meier method. Overall, in a total of 1158 patients, clearly differential survival rates were observed according to the histological subtypes, and SCNEC was associated with shortest survival. When examined according to the types of primary treatments, SCNEC was associated with significantly decreased survival when compared to SCC or A/AS, except for those treated with surgery. In patients with FIGO 2009 stage IVB cervical cancer, SCNEC was associated with decreased survival when compared to SCC or A/AS. Although current treatments with either surgery, chemotherapy or radiotherapy have some therapeutic efficacies, to improve the prognosis, novel effective treatments specifically targeting cervical SCNEC need to be developed.

Abstract
Small cell neuroendocrine carcinoma of the cervix (SCNECC) is an uncommon but aggressive uterine malignancy, the cause of which is generally associated with human papillomavirus (HPV) infection. A lack of clinical trials and evidence-based treatment guidelines poses therapeutic challenges to this rare tumor. At present, published data remain limited to case series and case reports. While clinical management has traditionally followed those of small cell neuroendocrine (SCNE) lung cancer relying on surgery, chemoradiation, and systemic chemotherapy, the prognosis remains dismal. Immune checkpoint inhibitors (ICIs), such as monoclonal antibodies that target programmed death-1 (PD-1) or programmed death-ligand 1 (PD-L1), atezolizumab and durvalumab have proven effective in extensive-stage SCNE lung cancer. Moreover, pembrolizumab has also proven beneficial effects when added onto chemotherapy in metastatic and recurrent HPV-associated non-SCNE cervical cancer. It holds promise to use ICIs in combination with chemoradiation to improve the clinical outcomes of patients with SCNECC. Future advances in our understanding of SCNECC biology - associated with the study of its genomic and molecular aberrations as well as knowledge from SCNE of lung and other extrapulmonary sites- would be helpful in discovering new molecular targets for drug development. Collaborative efforts and establishment of a SCNECC-specific biobank will be essential to achieve this goal.

Abstract
Neuroendocrine tumours of the gastrointestinal tract are rare. The incidence has increased in recent years due to improvements in diagnostic methods for detecting these lesions. These tumours have a poor prognosis, especially when detected at an advanced stage. The basis of the treatment is resection, and non-surgical treatments are also standard in the treatment process. The situation is similar in even rarer neuroendocrine tumours of the reproductive tract, which are associated with an equally poor prognosis. In this article, we focus on learning about the risk factors (including genetic mutations) that increase the risk of the disease and comparing the effectiveness of non-surgical treatments-chemotherapy, radiotherapy, peptide receptor radionuclide therapy, somatostatin analogues, and immunotherapy. The efficacy of these treatments varies, and immunotherapy appears to be a promising form of treatment; however, this requires further research.

Abstract
A two-tier system (limited- or extensive-stage) has been used for small cell neuroendocrine carcinomas of the cervix. Concordance probability estimates found that the 2018 FIGO staging system predicted outcome better than the two-tier system. 38% of patients had metastases at initial diagnosis, and an additional 38% at subsequent recurrence. 38 patients (60%) had brain imaging: 1 (3%) had brain metastasis at diagnosis and 8 (21%) at subsequent recurrence. Providers should have a low threshold for brain imaging in patients with advanced disease or neurologic symptoms.
Objectives To describe characteristics and outcomes of patients with small cell neuroendocrine carcinoma of the cervix (SCNCC) and determine the staging system most predictive of outcome—the two-tier (limited-stage [LS] vs. extensive-stage [ES]) or International Federation of Gynecology and Obstetrics (FIGO) staging system. Methods Patients with SCNCC evaluated at our institution from 1/1/1990–6/30/2021 were included. Medical records were reviewed for variables of interest. Appropriate statistical tests were performed to determine associations. Survival curves were created using the Kaplan-Meier method. Concordance probability estimates (CPEs) were calculated to evaluate the prediction probability of the staging systems. Results Of 63 patients, 41 had LS and 22 ES SCNCC. Patients with ES disease were significantly older than those with LS disease (median, 54 and 37 years, respectively; p < 0.001). Smoking status, race, and history of HPV were not associated with stage or outcomes. Forty-eight patients had metastatic disease (24 [50%] at initial diagnosis). The most common first sites of metastasis were lung (n = 20/48, 42%), lymph nodes (n = 19/48, 40%), and liver (n = 13/48, 27%). Nine patients had brain metastasis (8 symptomatic at recurrence; 1 asymptomatic at initial diagnosis). Both staging systems were associated with progression-free and overall survival. Adjusted CPE found the FIGO staging system was more predictive of outcomes than the two-tier staging system. Conclusions Providers should have a low threshold to obtain brain imaging for patients with SCNCC, especially in the presence of visceral metastases. FIGO staging should be used to classify SCNCC. Further research is necessary to understand prognostic factors of this rare disease.

Abstract
In the fifth edition of the World Health Organization classification of female genital tumors, neuroendocrine neoplasms are subcategorized as neuroendocrine tumors (NETs) of grade 1 (G1) and G2, and neuroendocrine carcinoma. NET G3 is not included, as it is for classification of pancreas tumors. Herein, we report 2 cases of "NET G3" of the uterine cervix with long-term follow-up. The patients are 40- and 36-yr-old women who presented with polypoid masses on the uterine cervix. Microscopic examination of hysterectomy specimens revealed tumor features similar to those of pancreatic NET G3 and intestinal type mucinous carcinoma cells invading the cervical stroma. In both cases, the NET component was positive for synaptophysin and chromogranin A, and negative for TTF-1. Mitotic counts were <1/2 mm 2 and 5/2 mm 2 , and the Ki-67 labeling indexes were 57% and 39%, respectively. Pathologic stage classifications (AJCC, version 9) were pT1b1, pN0, and cM0 (FIGO stage IB1), and both patients received adjuvant therapy. One patient had lung and pancreas metastases 4 to 8 yr after initial surgery, which were surgically removed. Both patients remain alive without evidence of recurrent disease 6 and 16 yr after initial surgery. The indolent clinical courses of these cases appear to indicate that cervical "NET G3" is biologically closer to NET than neuroendocrine carcinoma; thus, including uterine cervical "NET G3" in the classification may be justified. However, the optimal management for this tumor type remains undetermined.

Abstract
Neuroendocrine neoplasms are uncommon in the cervix with almost all representing neuroendocrine carcinomas (NECs), either small cell or large cell type. Cervical low-grade neuroendocrine tumors (NETs) are extremely rare with few recent reports using contemporary modern diagnostic criteria. We report 3 cases of cervical NET in patients aged 32 to 57 yr and undertake a review of the literature. The first case was a pure grade 2 NET with pelvic lymph node metastasis (FIGO stage IIIC1). In the second case, a grade 1 NET was associated with high-grade squamous intraepithelial lesion, adenocarcinoma in situ and human papillomavirus (HPV)-associated adenocarcinoma and was FIGO stage IA1. The third patient underwent chemoradiotherapy following a biopsy diagnosis of a high-grade NEC which was radiologically FIGO stage IIIC1 and salvage hysterectomy revealed residual tumor with features of a grade 1 NET. In all cases, the NET was diffusely positive with at least 2 of the neuroendocrine markers chromogranin, synaptophysin, and CD56. The first tumor was p16 negative and the third exhibited block-type immunoreactivity. Molecular tests revealed high risk HPV types 18 and 51 in the third case but no HPV in the first case. p16 immunohistochemistry and HPV molecular testing was not available in the second case. The patients remain disease free with follow-up ranging from 2 to 8 yr. Since a combination of NET and NEC is extremely rare at all sites due to a different pathogenesis, we speculate that in the third case, the NET developed out of the NEC as a "maturation" phenomenon secondary to chemoradiotherapy.

Abstract
Neuroendocrine carcinoma of the cervix is a rare and aggressive HPV-mediated malignancy with a high recurrence rate. Combination ipilimumab and nivolumab has been shown to effect disease response in pulmonary neuroendocrine carcinoma. We present three patients with recurrent neuroendocrine cervical carcinoma who experienced response to ipilimumab/nivolumab.
Neuroendocrine carcinoma of the cervix is a rare subtype of cervical cancer with a poor prognosis. Primary treatment of this disease involves a combination of surgery, chemotherapy, and radiation. The majority of patients will experience disease recurrence, for which there exist no treatment guidelines. Because of histologic similarities, small cell lung cancer has often informed management of extrapulmonary neuroendocrine carcinomas. Immunotherapy regimens, including a combination of ipilimumab and nivolumab, have been shown to have activity in small cell lung cancer. In this report, we present the cases of 3 patients with recurrent neuroendocrine carcinoma of the cervix who experienced durable response to a combination of ipilimumab and nivolumab.

Abstract
The thyroid metastasis from cervical cancer is extremely rare compared to other organs. It is sometimes difficult to distinguish primary tumors from metastases, as most metastatic thyroid nodules are asymptomatic. In this case, a 54-year-old woman had undergone radical hysterectomy due to cervical tumor of stage IB1 mixed adenoneuroendocrine carcinoma (MANEC) 5 years ago. After 3 years, ultrasound examination revealed a suspicious malignant nodule in the left lobe of thyroid gland at regular postoperative follow-up. This patient had no obvious clinical symptoms. The ultrasonography (US)-guided core needle biopsy (CNB) of the thyroid nodule was performed on the patient. The immunohistochemistry analyses revealed that it was poorly differentiated small-cell neuroendocrine carcinoma (SCNEC). Subsequently, the patient underwent left hemithyroidectomy plus isthmusectomy. The postoperative pathology and immunohistochemistry, combining with clinical history, confirmed that the thyroid nodule was a metastasis from cervical MANEC. Conventional chemotherapy and regular follow-up were carried out after the operation. The patient was readmitted 1 year later for pancreatic metastatic lesions and died 1 month after surgery. Early detection of metastatic cancer is potentially helpful, and when necessary, ultrasound-guided puncture biopsy can be utilized to further diagnose metastatic thyroid cancer.

Abstract
Neuroendocrine neoplasia is relatively uncommon in the female genital tract (FGT) and occurs at any site, most often the ovary and cervix. A unified dichotomous nomenclature, introduced by the World Health Organization Classification of Tumors in all fifth edition volumes, divides neuroendocrine neoplasms (NENs) into well-differentiated neuroendocrine tumors (NETs) and poorly differentiated neuroendocrine carcinomas (NECs). The term carcinoid tumor is retained in the ovary and represents the commonest FGT NEN. NEC is most common in the cervix and is usually admixed with another human papillomavirus-associated epithelial neoplasm. Despite shared neuroendocrine differentiation, NET and NEC show diverse etiology, morphology, and clinical behavior.

Abstract
Small-cell carcinomas are highly malignant tumors with neuroendocrine function and which often occur in the lungs. Primary small-cell neuroendocrine carcinomas of the gynecologic tract are extremely rare. This study aimed to evaluate the prevalence of independent predictors related to the prognosis and overall survival of patients with small-cell neuroendocrine carcinomas of the gynecologic tract. Patients with gynecologic small-cell neuroendocrine carcinomas diagnosed between 1973 and 2015 were identified from the Surveillance, Epidemiology, and End Results database. Univariate and multivariate Cox risk regression analyses were performed to determine the independent predictors of overall survival. Overall survival was calculated using the Kaplan–Meier method, and the log-rank test was used for comparison. We included 5,15,393 eligible carcinomas in the present study; the prevalence of gynecologic small-cell neuroendocrine carcinomas was 0.121% (N = 622). Multivariate analysis indicated that advanced age, stage III and IV cancer, and no chemotherapy treatment may be predictors of poor small-cell neuroendocrine cervical carcinoma prognosis. Stage III and IV cancer and lack of surgery, radiotherapy, or chemotherapy were identified as potential predictors of poor prognosis in patients with ovarian small-cell neuroendocrine carcinoma. Kaplan–Meier analysis suggested that the median survival was 19, 11, and 12 months for cervical, ovarian, and endometrial small-cell neuroendocrine carcinomas, respectively. The 1-, 3-, and 5-year overall survival rates were as follows: 58.8, 31.4, and 26.1%, respectively, for small-cell neuroendocrine cervical carcinoma; 46.3, 23.5, and 22.0%, respectively, for ovarian small-cell neuroendocrine carcinoma; and 49.4, 29.4, and 25.9%, respectively, for endometrial small-cell neuroendocrine carcinoma. Our findings indicate that comprehensive and individualized treatment of small-cell neuroendocrine carcinomas of the gynecologic tract may prolong patient survival, although further studies are required.

Abstract
Simple Summary Neuroendocrine refers to the cells that synthesize and secrete messenger chemicals such as neuropeptides and amines. Neuroendocrine neoplasms (NENs) are aggressive tumors arising from neuroendocrine cells, with an annual incidence of 6.98/100,000 and a prevalence of 170,000 in the United States. Primary gynecologic NENs constitute ≤2% of female reproductive tumors. NENs of the gynecologic tract are associated with high recurrence rates and dismal prognosis, making their treatment challenging. This article focuses on the updated staging classifications, clinicopathological characteristics, imaging, and management of NENs of the gynecological tract. Abstract Gynecological tract neuroendocrine neoplasms (NEN) are rare, aggressive tumors from endocrine cells derived from the neuroectoderm, neural crest, and endoderm. The primary gynecologic NENs constitute 2% of gynecologic malignancies, and the cervix is the most common site of NEN in the gynecologic tract. The updated WHO classification of gynecologic NEN is based on the Ki-67 index, mitotic index, and tumor characteristics such as necrosis, and brings more uniformity in the terminology of NENs like other disease sites. Imaging plays a crucial role in the staging, triaging, restaging, and surveillance of NENs. The expression of the somatostatin receptors on the surface of neuroendocrine cells forms the basis of increasing evaluation with functional imaging modalities using traditional and new tracers, including 68Ga-DOTA-Somatostatin Analog-PET/CT. Management of NENs involves a multidisciplinary approach. New targeted therapies could improve the paradigm of care for these rare malignancies. This article focuses on the updated staging classifications, clinicopathological characteristics, imaging, and management of gynecologic NENs of the cervix, ovary, endometrium, vagina, and vulva, emphasizing the relatively common cervical neuroendocrine carcinomas among these entities.

Abstract
Purpose Neuroendocrine cervical carcinoma (NECC) is an uncommon malignancy of the female reproductive system. This study aimed to evaluate cancer-specific mortality and to construct prognostic nomograms for predicting the survival of patients with NECC. Methods we assembled the patients with NECC diagnosed between 2004 to 2015 from the Surveillance, Epidemiology, and End Results (SEER) database. Meanwhile, we identified other patients with NECC from the Wenling Maternal and Child Health Care Hospital between 2002 to 2017. Fine and Gray’s test and Kaplan–Meier methods were used to evaluate cancer-specific mortality and overall survival (OS) rates, respectively. Nomograms were constructed for predicting cancer-specific survival (CSS) and OS for patients with NECC. The developed nomograms were validated both internally and externally. Results a total of 894 patients with NECC were extracted from the SEER database, then classified into the training cohort (n = 628) and the internal validation cohort (n = 266). Besides, 106 patients from the Wenling Maternal and Child Health Care Hospital served as an external validation cohort. Nomograms for predicting CSS and OS were constructed on clinical predictors. The validation of nomograms was calculated by calibration curves and concordance indexes (C-indexes). Furthermore, the developed nomograms presented higher areas under the receiver operating characteristic (ROC) curves when compared to the FIGO staging system. Conclusions we established the first competing risk nomograms to predict the survival of patients with NECC. Such a model with high predictive accuracy could be a practical tool for clinicians.

Emerging Therapeutic Concepts and Latest Diagnostic Advancements Regarding Neuroendocrine Tumors of the Gynecologic Tract. MEDICINA (KAUNAS, LITHUANIA) 2021; 57:medicina57121338.

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
To explore the incidence and prognosis trends for high-grade cervical neuroendocrine tumor (HGCNET) and construct a nomogram to predict prognosis for HGCNET. Annual age-adjusted incidence of HGCNET from 1975 to 2015 was retrieved from the Surveillance, Epidemiology, and End Results program, the linear regression, poisson regression and annual percentage changes were used to assess the incidence trend. Also, trends for relative survival (RS) and overall survival (OS) in HGCNET patients from 1975 to 2015 were evaluated. From 1988 to 1975, 514 HGCNET patients were selected and divided into two cohorts with a ratio of 7:3. Nomogram to predict OS for these patients was constructed and validated. The incidence trend for HGCNET was unchanged in the past four decades (P = 0.734), but the proportion of HGCNET in diagnosed cervical cancer slightly increased from 0.9% in 1975 to 1.9% in 2015 (P < 0.001). The 5-year RS and OS for HGCNET in the study periods decreased steadily (RS: P = 0.009; OS: P = 0.008). Nomogram incorporating age, T stage, lymph-node positive, distant metastasis and surgery was constructed. The C-index of the nomogram was 0.716 (0.680-0.752), which was higher than the FIGO staging system. The incidence of HGCNET remained unchanged in the past four decades but the proportion of HGCNET has slightly increased. Besides, a steadily decreasing survival for HGCNET was observed in the study periods. A nomogram was constructed to better predict prognosis for HGCNET.

Abstract
OBJECTIVE Recurrent cervical cancer is hard to treat when occurring in a previous radiated area and unresectable or distant metastasis. We present three such cases who achieved complete remission (CR) after chemoradiotherapy and pembrolizumab. CASE REPORT Case 1 was diagnosed with cervical adenocarcinoma, stage IVB. She obtained CR after concurrent chemoradiotherapy (CCRT) and post-CCRT adjuvant chemotherapy and bevacizumab. Recurrence at previous irradiated sacral bone was controlled with pembrolizumab and CCRT using proton therapy (PT). Case 2 was diagnosed with stage IVB squamous cell carcinoma. First recurrence occurred at inguinal lymph node (LN). Secondary recurrence occurred at paraaortic LN ten years later. PT with chemotherapy and pembrolizumab achieved CR. Case 3 had a small cell carcinoma (stage IVB) with bone metastasis. She had CR to CCRT with etoposide-cisplatin. Liver metastasis was salvaged with CCRT and pembrolizumab. CONCLUSION CCRT with pembrolizumab is potentially curative for recurrent cervical cancer conventionally amenable for palliation.

Abstract
Objective This study aimed to explore the prognostic factors and outcomes of patients with neuroendocrine tumors (NETs) of the cervix and to determine appropriate treatment. Methods A single-institution retrospective analysis of 172 patients with NETs was performed based on the new International Federation of Gynecology and Obstetrics (FIGO 2018) staging system. Results Among the 172 eligible patients, 161 were diagnosed with small cell neuroendocrine carcinoma (SCNEC), six with large cell neuroendocrine carcinoma, four with typical carcinoid tumors and one with SCNEC combined with an atypical carcinoid tumor. According to the FIGO 2018 staging guidelines, 31 were stage I, 66 were stage II, 57 were stage III, and 18 were stage IV. The 5-year survival rates of patients with stage I–IV disease were 74.8%, 56.2%, 41.4% and 0%, respectively. The 5-year progression-free survival rates of patients with stage I–IV disease were 63.8%, 54.5%, 30.8% and 0%, respectively. In the multivariate analysis, advanced FIGO stage, large tumor and older age were identified as independent variables for 5-year survival in patients with stage I–IV disease. FIGO stage, tumor size and para-aortic lymph node metastasis were independent prognostic factors for 5-year progression-free survival in patients with stage I–IV disease. For the patients receiving surgery (n = 108), tumor size and pelvic lymph node metastasis were independent prognostic factors for 5-year survival, and pelvic lymph node metastasis for 5-year progression-free survival. In stage IVB, at least six cycles of chemotherapy (n = 7) was associated with significantly better 2-year OS (83.3% vs. 9.1%, p < 0.001) and 2-year PFS (57.1% vs. 0%, p = 0.01) than fewer than six cycles of chemotherapy(n = 11). Conclusion Advanced FIGO stage, large tumor, older age and lymph node metastasis are independent prognostic factors for NETs of the cervix. The TP/TC and EP regimens were the most commonly used regimens, with similar efficacies and toxicities. Standardized and complete multimodality treatment may improve the survival of patients with NETs.

Abstract
Objective Neuroendocrine cervical cancer (NECC) is a rare cervical cancer with high aggressivity that causes poor prognosis even in the early stage. Given other neuroendocrine carcinomas and other types of cervical cancer have been proved to have expression of programmed cell death protein 1 ligand 1(PD‐L1) and poly ADP‐ribose polymerase‐1(PARP1), we would measure and analyze these proteins in this invasive cancer. The purpose of this study is to investigate the application value of PD‐1/PD‐L1 and PARP1 inhibitors in NECC. Methods The NECC cases in our center with formalin‐fixed paraffin‐embedded tissue blocks were collected, and immunohistochemical (IHC) staining of PD‐L1, PARP1, Mismatch repair proteins (MMRs), and P53 was performed. Chi‐square test was used to analyze associations between various protein expressions. We analyzed the efficacy of immunotherapy in a recent patient with secondary recurrence after two courses of chemotherapy. Results After rigorous screening, 20 cases were finally included. Three cases did not undergo surgical treatment because of their advanced stage. Twelve (60%) developed distant metastases or relapsed within five years, and most of them within two years. The positive rate of PD‐L1 and PARP1 were 70% and 75% respectively. Among all the cases, microsatellite instability (MSI) was seen in six cases (30%) and abnormal p53 expression was in 15 patients (75%). PD‐L1 was associated with PARP1 expression in the MSI subgroup. The patient treated with chemotherapy + VEGF inhibitor (VEGFi) + programmed cell death protein 1(PD‐1) inhibitor had an excellent improvement in clinical symptoms, tumor markers, and mass size. Conclusion The IHC results of PD‐L1, PARP1, and MMRs suggested that NECC was the target of immunotargeted therapy. Our case confirmed that immune checkpoint therapy was effective in patients with PD‐L1 positive and MMRs loss. Considering the clinical practicability, more cases should be collected, and effective biomarkers still need to be further searched.

Abstract
A case of cervical neuroendocrine carcinoma (NEC) of the uterine cervix (NECUC) was presented. After total hysterectomy with bilateral salpingo-oophorectomy and adjuvant chemotherapy, a left renal tumor and a pancreatic lesion developed and were both diagnosed on pathological examination as metastases from NEC. In addition, a brainstem metastasis causing neurologic signs developed. The brain lesion was treated by stereotactic radiotherapy (SRT) and the renal and pancreatic lesions by stereotactic body radiotherapy (SBRT). Despite control of the renal and pancreatic lesions, multiple small lung metastases developed later. Recurrence and newly developed brain metastases were treated by repeat stereotactic radiosurgery (SRS)/SRT successfully. Chemotherapy was continued and controlled the lung metastases until three and a half years after the initial operation of the uterus.
