Adenoid cystic carcinomas (ADCCs) are uncommon tumors, comprising < 1% of all head-and-neck cancers and 20%-25% of all salivary cancers. The most common presenting symptom of the lesion is a slowly growing mass followed by pain due to the propensity of these tumors for perineural invasion. The tumor is most often clinically deceptive by its small size and slow growth, which actually overlies its extensive subclinical invasion and marked ability for early metastasis making the prognosis questionable, aptly referred as "wolf in sheep's clothing...

Salivary glands may give rise to a wide spectrum of different tumors. This review concentrates on 4 salivary gland tumors that have been accepted in the recent literature as new neoplastic entities: mammary analog secretory carcinoma, cribriform adenocarcinoma of minor salivary glands (CASG), sclerosing polycystic adenosis/adenoma (SPA), and the mucinous/secretory variant of myoepithelioma. Mammary analog secretory carcinoma is a distinctive low-grade malignant salivary cancer that harbors a characteristic chromosomal translocation, t(12;15) (p13;q25), resulting in an ETV6-NTRK3 fusion...

There are no established protocols for the optimum surgical margin required for salivary gland malignancies. Factors including histologic diagnosis and TNM stage have been shown to be important in prognosis and survival outcome and mandate special consideration of margin size. Salivary cancers are treated differently at different anatomic sites, and different histologic types show a propensity for major or minor glands. Low-grade malignancies are treated with soft tissue margins of 1 cm or less. The facial nerve is preserved unless infiltrated and encased...

This review concentrates on three salivary gland tumors that have been accepted in the recent literature as new neoplastic entities: mammary analog secretory carcinoma (MASC), sclerosing polycystic adenoma (SPA) and cribriform adenocarcinoma of tongue and other minor salivary glands (CAMSGs). MASC is a distinctive low-grade malignant salivary cancer that harbors a characteristic chromosomal translocation, t(12;15) (p13;q25) resulting in an ETV6-NTRK3 fusion. SPA is a rare lesion often mistaken histologically for low-grade salivary carcinoma...

BACKGROUND: Salivary gland cancer is a common type of head and neck cancer characterized by occasional deep invasion and lung metastasis. The precise role of sex steroid hormones in salivary gland cancer is unclear. To address this issue, we investigated whether the estrogen axis modulates salivary adenocarcinoma (SAC) and whether hormone therapy can be an effective treatment. MATERIALS AND METHODS: The estrogen receptor (ER) was overexpressed in HSG human SAC cells that lack endogenous ER and the cells were treated with and without 17β-estradiol (E2)...

Salivary gland cancer (SGC) represents the most common malignancy in the head and neck region, and often metastasizes to the lungs. The helix-loop-helix ID1 protein has been shown to control metastatic progression in many types of cancers. Using two different approaches to target the expression of ID1 (genetic knockdown and progesterone receptor introduction combined with progesterone treatment), we previously determined that the aggressiveness of salivary gland tumor ACCM cells in culture was suppressed. Here, using the same approaches to target ID1 expression, we investigated the ability of ACCM cells to generate lung metastatic foci in nude mice...

There is a high demand for a non-invasive, rapid, and highly accurate tool for disease diagnostics. Recently, saliva based diagnostics for the detection of specific biomarkers has drawn significant attention since the sample extraction is simple, cost-effective, and precise. Compared to blood, saliva contains a similar variety of DNA, RNA, proteins, metabolites, and microbiota that can be compiled into a multiplex of cancer detection markers. The salivary diagnostic method holds great potential for early-stage cancer diagnostics without any complicated and expensive procedures...

REVIEW
Jennifer R Cracchiolo, Ashok R Shaha
Parotidectomy for parotid cancer includes management of primary salivary cancer, metastatic cancer to lymph nodes, and direct extension from surrounding structures or cutaneous malignancies. Preoperative evaluation should provide surgeons with enough information to plan a sound operation and adequately counsel patients. Facial nerve sacrifice is sometimes required; but in preoperative functioning nerves, function should be preserved. Although nerve involvement predicts poor outcome, survival of around 50% has been reported for primary parotid malignancy...

INTRODUCTION: Lymphoepithelial carcinoma (LEC) of the salivary glands is extremely rare worldwide, with studies limited to small case reports and case series from endemic areas (Southern China, Arctic Inuits) and strong association to Epstein Barr Virus (EBV). Studies on non-endemic regions are even more limited given the reality of only sporadic cases in these areas. Using the National Cancer Database (NCDB), we present the largest study on salivary LEC from a non-endemic region, the United States...

BACKGROUND: Management of the neck in patients with salivary gland cancer is controversial. This study aimed to identify clinicopathologic characteristics associated with regional metastases and regional recurrence in patients with salivary gland carcinoma. METHODS: Of 363 study patients, 51 underwent therapeutic neck dissection (TND) and 312 underwent either elective neck dissection (END, n = 110) or no neck dissection (NoND, n = 202). Univariate and multivariate analyses were performed to identify clinicopathologic characteristics associated with regional metastases and recurrence...

BACKGROUND: Salivary Adenoid cystic carcinoma (SACC) patients with local invasion and lung metastasis are often resistant to conventional therapy such as operation, chemotherapy and radiotherapy. To explore the underling mechanisms, we studied the roles of miRNA in regulating invasiveness of SACC cells. METHODS: MicroRNA profiling was done in SACC cells with microarray. MiRNA mimics or antisense oligonucleotide was transfected and invasiveness of SACC cells was evaluated by adhesion assay and transwell assay...

INTRODUCTION: The long-term sequelae of radioactive iodine (RAI) for differentiated thyroid cancer (DTC) in pediatric and young adult patients are not well-defined. Epidemiologic analyses of second primary malignancy (SPM) risk have only been performed in the adult population. Existing data are limited to case series with limited follow-up. The objective of this study was to analyze the elevated risk of SPM attributable to RAI in young patients treated for DTC. METHODS: Population-based analysis of 3850 pediatric and young adult patients (<25 years old) undergoing treatment with surgery with/without RAI for DTC, followed in the Surveillance, Epidemiology, and End Results cancer registry (1973-2008), equating to 54,727 person-years at risk (PYR)...

Lymphoepithelioma-like carcinoma (LELC) of salivary glands is a rare kind tumor. In this study, the authors evaluated 21 patients with LELC of salivary glands who had long-term follow-up. Clinical characteristics, Epstein-Barr virus (EBV) infection, immunohistochemical features, oncoprotein expression, treatments, and outcomes were analyzed. All patients were Chinese. Their ages ranged from 20 to 73 years. All tumors showed the typical syncytial growth pattern of undifferentiated epithelial cells with a significant lymphocyte reaction...

BACKGROUND: Preoperative differentiation between high-grade malignancy and others (benign or low-grade tumors) is more important than differentiation between malignant and benign tumors for surgical planning, treatment outcome, and prognosis in salivary gland tumors. Fine needle aspiration cytology (FNAC) has a relatively low sensitivity for differentiating malignant from benign salivary tumors. However, the diagnostic performance of FNAC has not been studied in predicting high-grade salivary malignancy, which can significantly affect patient care...

Treatment options for adenoid cystic carcinoma (ACC) of the salivary gland, a slowly growing tumor with propensity for neuroinvasion and late recurrence, are limited to surgery and radiotherapy. Based on expression analysis performed on clinical specimens of salivary cancers, we identified in ACC expression of the neurotrophin-3 receptor TrkC/NTRK3, neural crest marker SOX10, and other neurologic genes. Here, we characterize TrkC as a novel ACC marker, which was highly expressed in 17 out of 18 ACC primary-tumor specimens, but not in mucoepidermoid salivary carcinomas or head and neck squamous cell carcinoma...

To contribute the order-made medicine for cancer treatments, we have originally searched several biomarkers in the last decade. Some have been used as immunohistochemically novel biomarkers for the cancer diagnosis, and the others have applied to molecular target for the cancer therapy. RB1-inducible coiled-coil 1 (RB1CC1; also known as FIP200) plays important roles in biological pathways such as cell cycle arrest and autophagy, and the nuclear expression has been established as a prognostic predictor in breast and salivary cancer patients...

Mesenchymal stem cells (MSCs) are the progenitors of stromal cells, which have been found to interact with cancer cells and represent an important target for cancer therapies. Salivary gland cancer is an aggressive malignant epithelial tumor and can easily disseminate to distant sites in vivo. In this work, we probed the role of MSCs in salivary gland cancer in an in vivo like tumor microenvironment by using a series of functional microfluidic devices for 2D and 3D assays. The results demonstrated that MSCs could be recruited by salivary gland cancer cells (ACC-M) and this effect was potentially mediated by TGF-β secreted by cancer cells...
