The prognostic role of modified Glasgow Prognostic Score (mGPS), neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) in patients with salivary duct carcinoma (SDC) remains unclear. We conducted a multi-institutional retrospective cohort study of 140 SDC patients. The survival impact of these hematological markers was evaluated using multivariate proportional hazard models.High mGPS (≥1) was significantly associated with worse survival (3-year overall survival (OS): 16.7% vs 66.1%, p-value=0...

OBJECTIVES: Two cases of epithelial-myoepithelial carcinoma are presented, one arising in the pleura and the other in the anterior mediastinum. The cases represent a unique distribution of these tumors within the thoracic cavity. METHODS: Both patients were men aged 25 and 68 years, respectively, who had chest pain and dyspnea. Imaging revealed an anterior mediastinal mass in one patient and a pleural-based tumor in the other. Neither patient had any history of malignancy, and physical examination did not disclose any tumor elsewhere...

BACKGROUND: Pre-clinical and clinical evidence suggests a rationale for the use of anti-angiogenic agents, including sorafenib, in recurrent and/or metastatic salivary gland carcinomas (RMSGCs). This study evaluates the activity of sorafenib in patients with RMSGCs and also investigates whether the activity of sorafenib could be related to its main tailored targets (i.e. BRAF, vascular endothelial growth factor receptor 2 [VEGFR2], platelet-derived growth factor receptor α [PDGFRα] and β, RET, KIT)...

BACKGROUND/AIM: Androgens are known to play a critical role in prostate cancer progression, but their effect on malignant phenotypes in salivary gland cancer is unclear. The androgen-androgen receptor (AR) axis may be involved in malignant phenotypes of salivary duct carcinoma (SDC) cells and therefore may be a new target for SDC treatment. To test this hypothesis, we investigated the effect of the androgen 5α-dihydrotestosterone (DHT) on proliferation, migration, and invasiveness of SDC cells...

Salivary duct carcinoma (SDC) is a high-grade adenocarcinoma arising from the ductal epithelium of salivary glands which rarely involves the minor salivary glands. The varied histological presentation in the minor salivary gland tumors makes them the most heterogeneous group of neoplasms, making the diagnosis a challenge. This report highlights the importance of immunohistochemical markers in the definitive diagnosis of SDC.

Salivary duct carcinoma (SDC) is an aggressive adenocarcinoma of the salivary glands associated with poor clinical outcome. SDCs are known to carry TP53 mutations in about 50%, however, only little is known about alternative pathogenic mechanisms within the p53 regulatory network. Particularly, data on alterations of the oncogenes MDM2 and CDK4 located in the chromosomal region 12q13-15 are limited in SDC, while genomic rearrangements of the adjacent HMGA2 gene locus are well documented in subsets of SDCs. We here analyzed the mutational status of the TP53 gene, genomic amplification of MDM2, CDK4 and HMGA2 rearrangement/amplification as well as protein expression of TP53 (p53), MDM2 and CDK4 in 51 de novo and ex pleomorphic adenoma SDCs...

INTRODUCTION: The most common etiology for Oral Squamous Cell Carcinoma (OSCC) is tobacco and tobacco related products which cause nuclear damage to the keratinocytes. The chemical carcinogens not only affect the lining of oral epithelium but also affect the lining epithelium of the excretory ducts of the salivary glands. Thus, there is a possibility of epithelial dysplasia of the salivary duct epithelium which may lead to potential malignant transformation. AIM: The study was performed to see the changes in the minor salivary glands and excretory ducts in cases of oral epithelial dysplasia and OSCC...

Epithelial-myoepithelial carcinoma (EMC) is a rare tumor, especially in the minor salivary glands. This case report describes a 40-year-old man who presented with an EMC on the palate. Histologically, the tumor was characterized by a biphasic structure consisting of duct-lining cuboidal cells in the inner layer and clear myoepithelial cells in the outer layer. The clear cells predominated, and the diagnosis was confirmed with immunohistochemical staining. The inner cuboidal epithelial cells were positive for cytokeratins, whereas the outer cells were positive for S-100 protein and smooth muscle actin...

BACKGROUND: Polymorphous low-grade adenocarcinoma (PLGA) remains a diagnostic challenge for most pathologists due to its large spectrum of histological patterns. In this study, the expression of two new markers recently described for salivary gland tumors was studied in PLGA. METHODS: The morphology of 33 cases of PLGA was carefully evaluated using hematoxylin-and-eosin-stained sections and confirmed by immunohistochemistry for cytokeratin 7, vimentin, and S-100...

Mammary analogue secretory carcinoma (MASC) is a recently described salivary gland tumor that shares the same histologic appearance and ETV6 gene (12p13) rearrangement as secretory carcinoma of the breast. Prior to its recognition, MASC cases were commonly labeled acinic cell carcinoma and adenocarcinoma, not otherwise specified. Despite distinctive histologic features, MASC may be difficult to distinguish from other salivary gland tumors, in particular zymogen-poor acinic cell carcinoma and low-grade salivary duct carcinoma...

A 76-year-old Japanese woman had noticed an asymptomatic and palpable mass in her left parotid gland region for 20 years. The tumor had showed rapid growth during the last two months. Therefore, the tumor was clinically suspected of being a malignant tumor and was surgically resected. A histopathological examination revealed that the tumor consisted of two different histopathological neoplastic components accompanied by hyalinized fibrosis at the center of the tumor. The two-neoplastic components were squamous cell carcinoma and salivary duct carcinoma...

Diagnosis of midline neck swellings may give a myriad of options, ranging from ranula, thyroglossal duct cyst, cystic hygroma, cystic lymphangioma, epidermoid, dermoid and teratoid cysts to benign or malignant neoplasms of the mucosa or salivary glands and also rare skin appendage tumours like pilomatricoma or pilomatrix carcinoma. Various pitfalls are encountered in diagnosing these midline swellings as most of the features are overlapping. Careful history and examination have to be complemented with other diagnostic aids such as conventional radiography, ultrasonography, aspiration cytology and computed tomography to arrive at a correct diagnosis...

CASE 1: A 67-year-old Asian female was diagnosed with locally advanced high-grade salivary duct carcinoma in June 2011. Molecular analysis revealed human epidermal growth factor receptor 2 (HER-2) amplification. She received adjuvant therapy with carboplatin/paclitaxel/ trastuzumab and maintenance of trastuzumab. Upon disease progression, trastuzumab could not be continued due to lack of financial coverage. Instead, she was treated with compassionate use of lapatinib from April 2013 and standard 5-fluorouracil...

BACKGROUND: The authors hypothesized that histogenetic classification of salivary duct carcinoma (SDC) could account for de novo tumors and those with morphologic or molecular evidence (pleomorphic adenoma gene 1 [PLAG1], high-mobility group AT hook 2 [HMGA2] rearrangement, amplification) of pleomorphic adenoma (PA). METHODS: SDCs (n = 66) were reviewed for morphologic evidence of PA. PLAG1 and HMGA2 alterations were detected by fluorescence in situ hybridization (FISH)...

Tumors of the head and neck form a heterogeneous group of benign and malignant neoplasms with significant differences in biological behavior and therapeutic strategies. Squamous cell carcinomas (SCC) of the larynx, pharynx and oral cavity represent the most frequent and, thus, clinically most important malignant neoplasms in this anatomical region. Similar to other neoplasms, grading of head and neck malignancies is based on evaluation of the tumor histology usually including both architectural and cytological features; however, the current consensus grading for head and neck SCC is of limited prognostic and therapeutic value and the reproducibility is low...

Transcription factor SRY-related HMG-box 10 (SOX10) is an important marker for melanocytic, schwannian, myoepithelial, and some salivary gland tumors. The aim of this study was to investigate SOX10 expression more thoroughly in the salivary gland neoplasms, including mammary analogue secretory carcinoma and hyalinizing clear cell carcinoma harboring specific genetic rearrangements. A new rabbit monoclonal anti-SOX10 antibody (clone EP268) was used to examine SOX10 expression in 14 different types of salivary gland tumors...

CONCLUSION: The 3-year progression-free survival rate of non-invasive salivary duct carcinoma (SDC) or adenocarcinoma not otherwise specified (NOS) was significantly better than that of invasive SDC or adenocarcinoma NOS in Carcinoma ex pleomorphic adenoma (CXPA). The presence of invasion is an important prognostic factor for SDC and adenocarcinoma NOS in CXPA. OBJECTIVES: CXPA is a rare parotid gland malignant tumor for which therapy is not yet standardized. The purpose of this study was to review the characteristics of CXPA patients and to analyze their outcomes in the Northern Japan Head and Neck Cancer Society...

Metastatic salivary gland carcinoma is a rare malignancy. A subset of these tumors overexpresses the human epidermal growth factor receptor 2 (HER-2), which is considered a poor prognostic marker. Targeted therapy with the monoclonal antibody trastuzumab can be a treatment option in these patients. We describe six cases of metastatic salivary gland carcinoma treated with trastuzumab in combination with a taxane. Three of these patients had salivary duct cancer, two had mucoepidermoid carcinoma and one patient was treated for acinic cell carcinoma...
