Abstract
Mixed neuroendocrine-non-neuroendocrine neoplasms (MiNENs) are rare tumors recently characterized by the presence of both neuroendocrine and non-neuroendocrine components within the same tumor tissue. Although MiNEN found their place in the WHO classification for various organs, this composite tumor in the head and neck region remains exceptionally rare. We present a case of primary oral MiNEN in a 64-year-old male located on the left side of lower gingiva. Biopsy raised suspicion of neuroendocrine carcinoma (NEC) and the patient underwent partial mandibulectomy. The resected specimen showed two distinct components of NEC and squamous cell carcinoma (SCC) with the confirmation of immunohistochemical markers. There has been no sign of recurrence nor metastasis 6 years after the surgery. In addition, we have conducted a review of published cases with potential relevance to this entity, resulting in five cases. The diverse terminology reinforces the need for a standardized classification system of oral/head and neck MiNENs.

Abstract
Malignant myoepithelioma of the head and neck (HNMM) is a rare malignancy, and its characteristics and survival rates have not been well-defined. This study aimed to define the epidemiology of HNMM and identify the prognostic factors associated with the disease. Data on all patients diagnosed with HNMM between 1991 and 2016 were gathered from the Surveillance Epidemiology and End Results (SEER) database. The demographics, clinicopathological characteristics, treatment, and prognoses of the patients were described. Cox regression analysis was used to identify the prognostic factors, and the prognostic nomograms for overall survival (OS) and disease-specific survival (DSS) were constructed. A total of 333 cases of HNMM were identified. The average age at diagnosis was 60.6 years, and 50.1% of the patients were men. After diagnosis, 46.2% of patients underwent surgery alone, 43.5% of patients underwent surgery and radiotherapy, and 3.6% of patients received only radiotherapy. Survival analysis showed that the 5-year OS and DSS for all HNMM patients were 69.7 and 82.1%, respectively. In the multivariate analysis model, the undifferentiated pathological grade (P <0.05) and M1 in the M category (P <0.01) were independent prognostic factors for poor OS and DSS, whereas the use of surgical resection was an independent favorable prognostic factor for both OS and DSS (P <0.05). The prognostic nomograms for OS and DSS prediction were constructed; the C-index values for OS and DSS prediction were 0.78 (95% CI 0.70–0.86) and 0.79 (95% CI 0.67–0.90), respectively. In conclusion, this SEER data-based study demonstrated that HNMM patients often had a favorable prognosis, and distant metastasis, pathological grade, and the use of surgery contributed to their survival. Furthermore, we developed a prognostic nomogram to predict OS and DSS for HNMM patients to aid physicians in the clinical management of this rare disease.

Oral and Maxillofacial Neuroendocrine Carcinoma: A Systematic Review. Head Neck Pathol 2021; 16:525-537. [PMID: 34870796 PMCID: PMC9187797 DOI: 10.1007/s12105-021-01398-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/13/2021] [Accepted: 11/23/2021] [Indexed: 10/19/2022]
Abstract
The aim of the present study was to integrate the available data published in the literature on oral and maxillofacial neuroendocrine carcinomas concerning the demographic, clinical and histopathological features of this condition. An electronic search with no publication date restriction was undertaken in April 2021 in four databases. Eligibility criteria included reports published in English having enough data to confirm a definite diagnosis, always showing a neuroendocrine marker. Cases originating in the oropharynx, including base of the tongue and tonsils, were excluded. Outcomes were evaluated by the Kaplan-Meier method along with Cox regression. Twenty-five articles (29 cases) from nine different countries were detected. Mean patient age was 56.3 (± 17.5) years, with a slight male predilection. Symptomatology was present in 72.2% of informed cases. Regarding clinical presentation, a non-ulcerated nodule located in the gingiva with a mean size of 3.4 (± 2.0) cm was most frequently reported. Concomitant metastasis was identified in seven individuals. Histopathologically, most neoplasms were of the small cell type, and immunohistochemistry for both epithelial and neuroendocrine differentiation was used in 65.5% cases. Radical surgery was the treatment of choice in almost all cases, with or without adjuvant therapy. Mean follow-up was 20.5 (± 21.2) months, and only four patients developed recurrences. Eleven (44.0%) individuals died due to the disease. Ulcerated lesions were a prognostic factor. This study provides knowledge that can assist surgeons, oncologists, and oral and maxillofacial pathologists with the diagnosis and management of neuroendocrine carcinomas. Our findings demonstrated that the long-term prognosis of this lesion continues to be poor.

[PMID: 34786144 PMCID: PMC8581841] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2021] [Accepted: 06/20/2021] [Indexed: 06/13/2023]
Abstract
BACKGROUND The features and prognosis of adenosquamous carcinoma (ASC) in oral and maxillofacial region have not thoroughly investigated, the purpose of this study is to describe clinicopathologic characteristics, treatment, and prognostic factors of this disease. METHODS The data of 276 patients diagnosed with ASC in oral and maxillofacial region between 1975 and 2016 were collected from the Surveillance, Epidemiology, and End Results (SEER) database. The prognostic factors influencing overall survival (OS) and disease-specific survival (DSS) were identified by the Kaplan-Meier analysis and Cox regression analysis. The nomograms for OS and DSS were constructed to predict the prognosis of these patients. RESULTS Of 276 included patients, 62.7% were male and 37.3% were female, with an average age at diagnosis of 63.5 years. The most common primary site is oral cavity (170/276), followed by salivary gland (106/276). The 3-, and 5-year OS of patients with ASC in oral and maxillofacial region were 49.0% and 38.9%, while the 3-, and 5-year DSS were 67.7%, and 60.4%, respectively. Patients who underwent surgery had longer OS (mOS: 58 m vs. 8 m) and DSS (mDSS: 193 m vs. 18 m) than those who did not. Age, AJCC-T/N/M category as well as surgery were independently associated with OS. Advanced T stage, distant metastases, and surgery were independent factors for DSS. The prognostic nomograms for OS and DSS were constructed, and the C-indexes were 0.71 (95% CI 0.66-0.76) and 0.76 (95% CI 0.67-0.85), respectively. CONCLUSION Surgery was the favorable prognostic factor for both OS and DSS among patients with ASC in oral and maxillofacial region.
