In this study, we investigated purinergic receptor P2X7 and NACHT, LRR and PYD domains-containing protein 3 (NLRP3) inflammasome expressions, and their role in head and neck cancer. We found upregulation of purinergic receptor P2X7 and all NLRP3 inflammasome components in biopsied head and neck squamous cell carcinoma tissues. Similarly, the expression of purinergic receptor P2X7, apoptosis-associated speck-like protein containing CARD, and pro-form caspase 1 in A253 cells derived from epidermoid carcinoma were highly upregulated in comparison to normal Human Salivary Gland cell line...

BACKGROUND AND PURPOSE: Patient selection for proton therapy by comparing proton/photon treatment plans is time-consuming and prone to bias. RapidPlan™, a knowledge-based-planning solution, uses plan-libraries to model and predict organ-at-risk (OAR) dose-volume-histograms (DVHs). We investigated whether RapidPlan, utilizing an algorithm based only on photon beam characteristics, could generate proton DVH-predictions and whether these could correctly identify patients for proton therapy...

BACKGROUND: Nodular oncocytic hyperplasia (oncocytosis) of the salivary glands is a benign process that does not inherently require surgical excision. However, cytologic findings in fine-needle aspiration (FNA) of oncocytosis cases have not been well characterized previously, limiting preoperative identification. METHODS: All available cases of oncocytosis with corresponding FNA specimens were identified from the pathology archives of 3 academic institutions. Clinical, cytologic, and histologic findings were tabulated for all cases...

To develop a treatment protocol for (225)Ac-PSMA-617 alpha-radiation therapy in advanced stage, metastatic castration-resistant prostate cancer patients with PSMA-positive tumor phenotype. Methods: A dosimetry estimate was calculated based on time-activity-curves derived from serially performed (177)Lu-PSMA-617 scans extrapolated to the physical half-life of (225)Ac, assuming instant decay of instable daughter nuclides. Salvage therapies empirically conducted with 50kBq/kg (n = 4), 100kBq/kg (n = 4), 150kBq/kg (n = 2), 200kBq/kg (n = 4) (225)Ac-PSMA-617 were evaluated retrospectively regarding toxicity and treatment response...

PURPOSE: Approximately 20% of all salivary gland cancer patients who are treated with current treatment modalities will ultimately develop metastases. Its most common form, mucoepidermoid carcinoma (MEC) is a highly aggressive tumor with an overall 5-year survival rate of ~30%. Until now, several chemotherapeutic drugs have been tested for the treatment of salivary gland tumors, but the results have been disappointing and the drugs often cause unwanted side effects. Therefore, several recent studies have focused on the potential of alternative and/or complementary therapeutic options, including the use of silymarin...

BACKGROUND: Myoepithelial carcinoma of soft tissue is a rare, malignant neoplasm that is morphologically and immunophenotypically similar to its counterpart in salivary gland. It demonstrates myoepithelial differentiation, possessing both epithelial and myogenic characteristics. Thought to be chemotherapy insensitive, the optimal treatment regimen of this tumor has yet to be established and only a select few cases in the literature discuss treatment efficacy in detail. CASE PRESENTATION: Here we present a case of a young adult with metastatic myoepithelial carcinoma with an initial excellent response to systemic therapy utilizing carboplatin and paclitaxel with continued complete response after 3 years...

B7 Homolog 3 (B7-H3), a newly identified member of the B7 family, is over-expressed in various human cancers and plays a vital role in tumor progression. To identify the expression pattern of B7-H3 in human salivary adenoid cystic carcinoma (AdCC) and its underlying mechanisms, we characterized B7-H3 expression in AdCC tissue microarrays using immunohistochemical staining, and analyzed potentially associated molecules. The results showed that B7-H3 was highly expressed in salivary AdCC, compared with normal salivary glands...

BACKGROUND: Salivary gland carcinomas comprise a group of heterogeneous lesions with complex clinicopathological characteristics and distinct biological behaviors. However, recurrent or metastatic tumors are difficult to treat with currently available therapies. Cancer-testis antigens (CTAs) are detected in cancer cells but not in healthy normal tissues, with the exception of gametogenic tissues. CTAs are highly immunogenic proteins and thus represent ideal targets for cytotoxic T-lymphocyte-mediated specific immune therapy...

OBJECTIVES: The age of oral and pharyngeal cancer patients has reportedly decreased over the last decade, but most of the peer-reviewed literature regarding oral and pharyngeal cancer in individuals 0-19years of age (Y) is limited to specific tumor sites and/or types, or a small number of cases. Our aim is to characterize oral, salivary gland and pharyngeal cancer (OSPC) in 0-19Y in order to improve knowledge of the disease in young individuals. METHODS: Data on OSPC between 1970 and 2011 was taken from the Israel National Cancer Registry, and included patient age, gender, tumor site and tumor type...

There are many classes of noncoding RNAs (ncRNAs), with wide-ranging functionalities (e.g., RNA editing, mediation of mRNA splicing, ribosomal function). MicroRNAs (miRNAs) and long ncRNAs (lncRNAs) are implicated in a wide variety of cellular processes, including the regulation of gene expression. Incorrect expression or mutation of lncRNAs has been reported to be associated with several disease conditions, such a malignant transformation in humans. Importantly, pivotal players in tumorigenesis and cancer progression, such as c-Myc, may be regulated by lncRNA at promoter level...

Primary bronchopulmonary mucoepidermoid carcinoma (BPMEC) is a rare tumor. The fusion protein MECT1-MAML2 has been implicated as a causative genetic event in salivary and BPMECs. Several studies have shown the impact of MECT1-MAML2 on the diagnosis and prognosis of salivary gland mucoepidermoid carcinoma; however, few studies have been published regarding MECT1-MAML2 in the context of primary BPMEC. We describe the clinicopathologic, genetic, and outcome data of 16 patients with BPMEC. Clinicopathologic features were recorded from the electronic medical records...

BACKGROUND AND PURPOSE: Adenoid cystic carcinoma (ACC) of salivary glands is characterized by long-term distant metastasis, most commonly in lungs. No agreement has been reached about the role of surgical treatment of pulmonary lesions. We evaluated the long-term results of lung metastasectomy for ACC in order to identify factors that should be taken into account in selecting patients eligible for surgery and treatment planning. PATIENTS AND METHODS: A retrospective study was conducted on 109 patients selected from our institutional experience and from the International Registry of Lung Metastases...

Salivary adenoid cystic carcinoma (AdCC) is a common head and neck cancer with the propensity for local spread and distant metastasis. In our previous study, elevated expression of Anterior gradient 2 (AGR2) was detected in head and neck squamous cell carcinoma (HNSCC), associated with epithelial-mesenchymal transition (EMT) and cancer stemness. However, to date, the expression and function of AGR2 in AdCC has yet to be elucidated. In the present study, human AdCC tissue microarrays including 18 cases of normal salivary gland (NSG), 12 cases of pleomorphic adenoma (PMA) and 72 cases of AdCC were employed for immunohistochemical staining analysis...

Salivary gland carcinomas are rare tumours and therapy strategies are less standardized than in lung, gastric or breast cancer. Therapy is based on surgery, but not all carcinomas are completely resectable, e.g. because carcinomas often show infiltration of nerves. For further therapy decision pathology is recommended, but evaluation of potential targets for personalized therapy is not part of the routine panel. Many salivary gland carcinomas can be resistant to radio- and/or chemotherapy, which limits therapeutic options...
