Pathogenic gene fusions have been identified in several histologic types of salivary gland neoplasia, but not previously in acinic cell carcinoma (AcCC). To discover novel gene fusions, we performed whole-transcriptome sequencing surveys of three AcCC archival cases. In one specimen we identified a novel HTN3-MSANTD3 gene fusion, and in another a novel PRB3-ZNF217 gene fusion. The structure of both fusions was consistent with the promoter of the 5' partner (HTN3 or PRB3), both highly expressed salivary gland genes, driving overexpression of full-length MSANTD3 or ZNF217...

Adenoid cystic carcinoma (AdCC) is a malignant salivary gland tumor. To date, no cases of AdCC in first-degree relatives have been reported in the literature. We present a 50-year-old female (Case 1) and this patients' father (Case 2), both of whom were diagnosed with AdCC of the minor salivary glands. Histology of Case 1 demonstrated a tubulocribriform AdCC whereas Case 2 primarily was an AdCC of solid type. Both cases harbored the MYB-NFIB gene fusion as demonstrated by FISH and RNA-sequencing. After filtering and selection of putative deleterious variants, whole exome sequencing identified 18 germline variants in common between Case 1 and Case 2...

Salivary gland cancers comprise a small subset of human malignancies, and are classified into multiple subtypes that exhibit diverse histology, molecular biology and clinical presentation. Local disease is potentially curable with surgery, which may be combined with adjuvant radiotherapy. However, metastatic or unresectable tumors rarely respond to chemotherapy and carry a poorer prognosis. Recent molecular studies have shown evidence of androgen receptor signaling in several types of salivary gland cancer, mainly salivary duct carcinoma...

OBJECTIVE: 
Considering the higher rate of oral cancer, and reduction in salivary antioxidants in smokers as indicated in previous studies, antioxidant- containing nutrients such as green tea, seem to be beneficial in counteracting against oxidative stress in this group. This study assessed the salivary total antioxidant alteration in smokers compared to nonsmokers, after short-tem (7days) and long-term (3 weeks), green tea drinking. DESIGN: In this experimental study, 20 volunteer moderate-to-heavy male smokers, and 20 matched healthy non-smokers were selected to participate, according to the inclusion criteria...

BACKGROUND: The overexpression of histone deacetylases (HDACs) has been observed in many cancers and inhibition of specific HDACs has emerged as a new target for cancer therapy. We found that HDAC7 expression was selectively reduced by HDAC inhibitor apicidin in salivary mucoepidermoid carcinoma (MEC) cells. Here, we show that HDAC7 suppression has a potent anti-tumor effect in MEC cells. METHODS: HDAC7 was knocked down using HDAC7 siRNAs and cell proliferation was quantified...

Radiotherapy for head and neck cancer often has undesirable effects on salivary glands that lead to xerostomia or severe dry mouth, which can increase oral infections. Our goal is to engineer functional, three-dimensional (3D) salivary gland neotissue for autologous implantation to provide permanent relief. An immediate need exists to obtain autologous adult progenitor cells as the use of embryonic and induced pluripotent stem cells potentially pose serious risks such as teratogenicity and immunogenic rejection...

Salivary duct carcinoma (SDC) is a rare malignancy, frequently overexpressing androgen receptor (AR). Therefore, similar to AR-positive prostate cancer (PCa), AR-positive SDC patients benefit from androgen deprivation therapy and, after progression on ADT, might take advantage of Ra dichloride, a radiopharmaceutical approved for the treatment of castration-resistant PCa with symptomatic bone disease. We report the case of a 75-year-old man with castration-resistant SDC and osteoblastic bone metastases who, after Ra treatment, achieved adequate control of bone pain and bone lesion reduction with minor side effects...

BACKGROUND: Oral squamous cell carcinoma (OSCC) is the most common malignant tumour of the oral cavity. Detection of OSCC is currently based on clinical oral examination combined with histopathological evaluation of a biopsy sample. Direct contact between saliva and the oral cancer makes measurement of salivary metalloproteinase-9 (MMP-9) an attractive alternative. MATERIAL AND METHODS: In total, 30 OSCC patients and 30 healthy controls were included in this prospective study...

Severe xerostomia (dry mouth) compromises the quality of life in patients with Sjögren's syndrome or radiation therapy for head and neck cancer. A clinical management of xerostomia is often unsatisfactory as most interventions are palliative with limited efficacy. Following up our previous study demonstrating that mouse BM-MSCs are capable of differentiating into salivary epithelial cells in a co-culture system, we further explored the molecular basis that governs the MSC reprogramming by utilizing high-throughput iTRAQ-2D-LC-MS/MS-based proteomics...

Collective invasion of cells plays a fundamental role in tissue growth, wound healing, immune response and cancer metastasis. This paper aimed to investigate cytokeratin-14 (CK14) expression and analyze its association with collective invasion in the invasive front of salivary adenoid cystic carcinoma (SACC) to uncover the role of collective invasion in SACC. Here, in the clinical data of 121 patients with SACC, the positive expression of CK14 was observed in 35/121(28.93%) of the invasive front of SACC. CK14 expression in the invasive front, local regional recurrence and distant metastasis were independent and significant prognostic factors in SACC patients...

BACKGROUND: Pediatric salivary gland carcinomas (SGCs) are very rare. They differ from the adult SGCs in terms of epidemiologic and clinical behavior, being generally limited only to selected histotypes (e.g. low-grade mucoepidermoid [LG-MEC] and acinic cell cancer [AcCC]) and characterized by very good outcome. Our aim was to investigate therapeutic targets on a series of pediatric SGCs by immunohistochemical and molecular analysis. METHODS: A retrospective analysis was performed to search for cases of pediatric SGCs in the database of the Pediatric Oncology Unit at the Istituto Nazionale Tumori and in the Pathology database at the Gerhard-Seifert-Reference-Centre...
