Laryngoscope 2024; 134:1716-1724. [PMID: 37909690 DOI: 10.1002/lary.31123] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2023] [Revised: 09/15/2023] [Accepted: 10/10/2023] [Indexed: 11/03/2023]
Abstract
OBJECTIVES Secretory Carcinoma is a malignant salivary gland tumor, initially described in 2010. This rare tumor is associated with the translocation t(12;15) (p13;q25), resulting in the fusion gene ETV6-NTRK3. Since this tumor is quite rare, most publications describe only small cohorts of patients. We aimed to investigate the clinical, pathological, and prognostic features of this newly defined malignant entity. DATA SOURCES Pubmed, Google Scholar, and Web of Science databases. REVIEW METHODS All published articles between 2010 and 2023 were reviewed. Search terms included the terms "Mammary Analogue Secretory Carcinoma" and "Secretory Carcinoma". All articles published in English reporting on Secretory Carcinoma of salivary glands were retrieved. RESULTS One-hundred and 12 retrospective articles reporting a total of 674 patients were included, with 52% males and a mean age of 44.9 ± 18.9. The event rate for patients with advanced-stage disease (Stage 3/4) at presentation was 24.1% (95% CI 17.6%-31.9%, I2 = 9.2%), 14.6% for regional metastases (95% CI 10.5%-20%, I2 = 12%), and the event rate of distant metastasis was 8.4% (95% CI 5.5%-12.7%, I2 = 4.2%). Adjuvant radiotherapy was administered for 30.3% of patients (95% CI 24.1%-37.2%, I2 = 21.5%). The recurrence rate was 19% (95% CI 15.1%-23.8%, I2 = 5%). Survival outcomes showed a 17.2% death of disease rate for Secretory Carcinoma patients (95% CI 13.5%-21.8%, I2 = 7.3%). CONCLUSIONS Secretory Carcinoma is a rare and relatively newly defined entity arising in the parotid gland most commonly. Characterized as a low-grade tumor, the majority of patients are diagnosed at an early stage, without regional or distant disease, and the prognosis is relatively good. LEVEL OF EVIDENCE NA Laryngoscope, 134:1716-1724, 2024.

Kala PS, Gupta M, Thapliyal N. Efficacy of Fine-Needle Aspiration Cytology in Diagnosing Secretory Carcinoma of Salivary Gland: A Systematic Review and Meta-Analysis. Acta Cytol 2024; 68:83-106. [PMID: 38228123 DOI: 10.1159/000536249] [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: 11/23/2023] [Accepted: 01/10/2024] [Indexed: 01/18/2024]
Abstract
INTRODUCTION The diagnosis of salivary gland secretory carcinoma (SC) in fine-needle aspiration specimens is challenging because its low-grade nature makes it difficult to differentiate it from various benign or malignant salivary gland neoplasms. Currently, the gold standard is demonstration of ETV6-NTRK3 fusion gene. However, the decision for ordering this costly molecular testing can be facilitated by the correct recognition of its cytomorphological features. The aim of the review was to determine the accuracy of fine-needle aspiration cytology (FNAC) in diagnosis of salivary gland SC. The secondary objective was to recognize varied cytomorphological patterns, characteristic features of SC and differentiate it from other neoplasms. METHODS PubMed/MEDLINE, Science Direct, Embase, Cochrane review, and PROSPERO databases were searched for studies having the following key search terms: ("secretory carcinoma of salivary gland" OR "mammary analogue secretory carcinoma of salivary gland") AND ("Cytology" OR "Cytological features" OR "aspirate" OR "cytodiagnosis") published in the time frame of 2010 to June 2023. Studies reporting cytological features of the salivary gland tumors which were confirmed/diagnosed as SC on molecular investigation, were included in the systematic review. Finally, seventeen studies reporting a total of 45 cases were included in the metanalysis. RESULTS The sensitivity of the FNAC in diagnosing SC in salivary gland is 27.7% (95% CI: 16.6-42.5%). The LR+ (positive likelihood ratio) was 0.654 (0.344-1.245), LR- (negative likelihood ratio) was 1.023 (0.538-1.946), and diagnostic odds ratio was 0.421 (0.129-1.374). The molecular testing and/or immunohistochemistry performed on cell block increased the diagnostic accuracy. CONCLUSION Recognition of subtle cytomorphological patterns, i.e., papillary formation, clusters, and singly dispersed cells along with presence of fine intracytoplasmic vacuolations were the characteristic findings in majority of cases, confirmed with diagnostic molecular profiling. This may be helpful in identification of this rare entity with limited published literature and help in increasing diagnostic accuracy.

Abstract
Background: Mammary analogue secretory carcinoma (MASC) is characterized by similar histologic, immunohistochemical, and molecular features with breast secretory carcinoma. MASC usually occurs in adults. Case report: A 4-year-old boy presented with a right infra-auricular mass. Features of the tumor include solid, tubular, and papillary growth patterns, with homogenous eosinophilic secretions inside microcystic structures. Immunohistochemical stains showed strong, diffuse staining for CK7, S100, pan-TRK protein. P63 was positive in a peripheral pattern. Fluorescence in situ hybridization (FISH) analysis showed the characteristic ETV6-NTRK3 gene fusion. Conclusion: Typical histological, immunohistochemical, and molecular features are present in MASC occurring early in childhood.

Abstract
Mammary analogue secretory carcinomas (MASCs) of the parotid gland are considered as low-grade malignancies with good clinical outcome but lacking data regarding prognostic factors. We performed meta-analysis assessing prognostic factors for disease-free survival (DFS) and overall survival (OS) in 256 patients with MASCs of the parotid gland. A total of 73 studies have met the inclusion criteria and 76.3% of patients were seen with T1 and T2 tumors and negative neck nodes. Lymph node metastasis (57.4%) and distant recurrences (46.2%) were particularly found in T4 tumors (p < 0.001). DFS at 5 and 10 years was 77.9% and 47.2% compared to 88.1% and 77.2% for OS at the same time points. Male sex, T3-T4 tumors, and recurrent disease represented independent worse prognosticators for survival outcome. Altogether, parotid gland MASCs show good long-term outcome, but T4 tumors behave significantly more aggressive and require extended treatment strategies along with close follow-ups.

Abstract
OBJECTIVE The aim of this systematic review was to describe the epidemiology, diagnostic criteria, differential diagnosis, treatment, prognostic factors, and treatment outcomes of secretory carcinoma. STUDY DESIGN A comprehensive search of Lilacs, PubMed, Science Direct, and Web of Science databases was conducted to identify all case reports, letter to the editor, and histopathologic reclassifications regarding salivary gland secretory carcinoma published in English, Spanish, French, and Portuguese. RESULTS The final analysis included 119 studies, which totaled 642 secretory carcinoma diagnoses, with 239 case reports and 403 diagnostic reclassifications, mostly in the United States. The age range was 5 to 87 years, and cases were predominantly in males (58.7%) and mostly affecting the parotid glands (73.7%). The disease usually presents as a slow-growing, painless mass. The main differential diagnosis is acinic cell carcinoma, and the tumor is usually treated with surgery. The prognosis is considered favorable, although there have been reports of local recurrences, distant metastases, and deaths. CONCLUSIONS It is important that clinicians become aware of this salivary gland neoplasm and report clinical data, clinical course, management and long-term follow-up. There is an urgent need to conduct more clinical trials, especially on tropomyosin receptor kinase (TRK) inhibitors and other potential target therapy modalities.

Abstract
PURPOSE This retrospective study aimed to investigate the radiological features of head and neck mammary analogue secretory carcinoma (MASC) and systematically review previous publications and 11 new cases. METHODS We included patients with pathologically proven MASCs with preoperative CT or MRI images, including 11 patients from our hospital and 29 patients from 28 publications extracted after screening 645 abstracts. Two board-certified radiologists reviewed and evaluated all radiological images. The frequency of metastasis during the follow-up period in tumors with well- and ill-defined margins was compared using a Fisher's exact test. RESULTS The median age at diagnosis was 52.5 years (range, 7-78 years; 20 males). Of the 40 patients, those in their 50 s were the most common (10/40, 25.0%), and the main tumor site was the parotid gland (27/40, 42.5%). Characteristic radiological features included high intensity on T1WI in the cystic components and tumors frequently showed "papillary and cystic," which showed a projection into the cystic components, or "non-papillary and cystic" morphology, which did not show projection of the solid components. Tumor metastasis was found in 10/35 patients (28.6%) during the follow-up period, with a significant difference in frequency between the tumors with well- and ill-defined margin (well-defined (4/26) vs. ill-defined (6/9); P = 0.0074). CONCLUSION MASCs are newly recognized malignant tumors. Characteristic T1WI high intensity on MRI and predominant cystic morphology may reflect its unique histological profile. Ill-defined tumor margin status was related to frequent metastasis. Awareness of these characteristic radiological features can assist radiologists in better detection of this novel entity.

Abstract
BACKGROUND Mammary analogue secretory carcinoma (MASC) is a rare low-grade malignant salivary gland tumor. The morphological and immunohistochemical features of MASC closely resemble those of breast secretory carcinoma. The key characteristics of the lesion are a lack of pain and slow growth. There is no obvious specificity in the clinical manifestations and imaging features. The diagnosis of the disease mainly depends on the detection of the MASC-specific ETV6-NTRK3 fusion gene.
CASE SUMMARY This report describes a rare case of a 32-year-old male patient who presented with a gradually growing lesion that was initially diagnosed as breast-like secretory carcinoma of the right parotid gland. Imaging and histological investigations were used to overcome the diagnostic difficulties. The lesion was managed with right parotidectomy, facial nerve preservation, biological patch implantation to restore the resulting defect, and postoperative radiotherapy. On postoperative follow-up, the patient reported a mild facial deformity with no complications, signs of facial paralysis, or Frey’s syndrome.
CONCLUSION The imaging and histological diagnostic challenges for MASC are discussed.

Abstract
Mammary analog secretory carcinoma (MASC) is a new concept in diagnosis of head and neck tumors. MASC is often misdiagnosed as other tumors such as salivary acinic cell carcinoma. Management of MASC follows treatment of low-grade salivary gland neoplasm which is radical surgical excision. More advanced MASC are treated with radical excision, neck dissection, radiation and chemotherapy. No standard protocol has been established due to rarity of the disease.
Introduction Mammary analog secretory carcinoma (MASC) is a new diagnosis of head and neck tumors first reported in 2010. It was often misdiagnosed as salivary acinic cell carcinoma (AciCC). We present a patient with an asymptomatic parotid tumor that underwent deep lobe parotidectomy and postoperative radiation therapy. The final pathology showed MASC. Case presentation A 57-year-old male presented with an asymptomatic enlarging right parotid mass. A CT neck with IV contrast showed a 1.2 cm heterogeneously enhancing mass in the center of the right parotid gland without extraparotid extension. An FNA showed an epithelial neoplasm with papillary features. The patient underwent a right deep lobe parotidectomy with facial nerve dissection. The final pathology confirmed the diagnosis of MASC. He subsequently completed a 6-week course of radiation therapy and remained asymptomatic at his 30-month follow up. Discussion/conclusion Although MASC is considered a low-grade tumor in most cases, recurrence and disseminated disease are not uncommon. No standard treatment protocol has been established. This report aims to enhance the awareness of this diagnosis and provide a review of current treatments for head and neck oncology care providers.

Abstract
Mammary analogue secretory carcinoma (MASC) harboring ETV6 gene rearrangements was first described in the salivary gland with a relatively favorable prognosis and a possible molecular therapeutic target with pan-Trk inhibitors. Recently, primary MASC of the thyroid gland has been reported. We report a case of a 4.0 cm MASC arising from the left thyroid of a 58-year-old female with extrathyroidal extension. Initially, it was diagnosed by fine needle aspiration as suspicious for papillary thyroid carcinoma (PTC) and subsequently called a poorly differentiated carcinoma on resection. A final diagnosis of primary MASC of the thyroid was confirmed after an expanded immunohistochemical panel and identification of an ETV6 gene rearrangement by fluorescence in situ hybridization. Morphologically, the tumor was composed of solid, microcystic and focally papillary growth with dense fibrotic stroma and necrosis. Overlapping cytological features with PTC were identified, including foci of enlarged cells with irregular nuclear membranes/grooves. However, most of the cells contained prominent nucleoli with intraluminal and intracytoplasmic eosinophilic secretions. Immunohistochemically, the tumor cells were strongly positive for pancytokeratin, cytokeratin 7, PAX8, mammaglobin, and GCDFP-15, with rare staining for GATA3 and S100 and negative for TTF-1 and thyroglobulin. We report a rare case of a primary thyroid MASC, initially misdiagnosed as PTC. Pathologists should be aware of this entity and, given the similarities to PTC, have a high index of suspicion, prompting the addition of immunohistochemical and molecular studies. Furthermore, an accurate diagnosis is important because of the possible prognostic and treatment implications.

Abstract
Fine needle aspiration (FNA) has diagnostic and therapeutic value in the management of salivary gland cysts. Rendering an accurate diagnosis from an aspirated salivary gland cyst is challenging because of the broad differential diagnosis, possibility of sampling error, frequent hypocellularity of specimens, morphologic heterogeneity, and overlapping cytomorphology of many cystic entities. To date, there have been no comprehensive review articles providing a practical diagnostic approach to FNA of cystic lesions of salivary glands. This article reviews the cytopathology of salivary gland cysts employing 2017 World Health Organization terminology, addresses the accuracy of FNA, and presents The Milan System approach for reporting in cystic salivary gland cases. The utility of separating FNA specimens from salivary gland cysts, based upon the presence of mucin and admixed lymphocytes in cyst fluid is demonstrated. A reliable approach to interpreting FNA specimens from patients with cystic salivary gland lesions is essential to accurately determine which of these patients may require subsequent surgery.
