Background: Oestrogen has a physiological role throughout the body including oral cavity. The effects are mediated by binding to two receptors in nucleus alpha and beta, which are ligand-activated transcription factors. The alpha receptors have a prognostic significance in cancer of breast while in Adenoid cystic carcinoma of salivary glands the results are inconsistent. This study was conducted to determine the oestrogen receptor Alpha staining in adenoid cystic carcinoma of salivary gland...

Aberrant microRNA (miRNA/miR) expression has been reported in various cancer types. miR‑21, which is considered to be a proto-oncogene and is frequently overexpressed in certain cancer types, has been implicated in tumorigenesis. The aim of the present study was to investigate the effect of miR‑21 degradation on tumor progression and its potential mechanisms in human salivary adenoid cystic carcinoma (SACC) development. Results of reverse transcription‑quantitative polymerase chain reaction analysis indicated that SACC cells with high metastatic potential (SACC‑LM cells) exhibited a significantly higher expression of miR‑21 compared with SACC cells with a lower metastatic potential (SACC‑83 cells)...

Human papillomavirus-related carcinoma with adenoid cystic-like features is a newly described histologic variant of sinonasal tract carcinoma. The implications of this sinonasal malignancy is still being evaluated. There are a limited number of cases reported in the literature, and thus we seek to further characterize this patient population and review the histologic features of this malignancy with the following two cases. The behavior of this entity is as yet uncertain. Laryngoscope, 2018.

High-grade transformation (HGT)/dedifferentiation is an unusual phenomenon in salivary gland carcinomas. Here we report a case of adenoid cystic carcinoma (ACC) with HGT/dedifferentiation to myoepithelial carcinoma, occurring in the epipharynx of a 42-year-old woman. The surgically resected tumor was a pedunculated mass, 31 × 25 mm in size, which had two histologically distinct carcinomatous areas, including a high-grade sarcomatoid area composed of pleomorphic spindle cells and an area consisting of low-grade typical ACC...

Salivary gland cancer is an aggressive and painful cancer, but a rare tumor type accounting for only ~0.5% of cancer cases. Tumors of the salivary gland exhibit heterogeneous histologic and genetic features and they are subdivided into different subtypes, with adenoid cystic carcinomas (ACC) being one of the most abundant. Treatment of ACC patients is afflicted by high recurrence rates, the high potential of the tumors to metastasize, as well as the poor response of ACC to chemotherapy. A prerequisite for the development of targeted therapies is insightful genetic information for driver core cancer pathways...

BACKGROUND/AIM: Adenoid cystic carcinoma (AdCC) is a rare cancer of the salivary gland with high risk of recurrence and metastasis. Wnt signalling is critical for determining tumor grade in AdCC, as it regulates invasion and migration. β-catenin dephosphorylation plays an important role in the Wnt pathway, but its underlying molecular mechanism remains unclear. MATERIALS AND METHODS: Because the regulatory subunits of protein phosphatase 2A (PP2A) drive Wnt signalling via target molecules, including β-catenin, we used qRT-PCR and immunoblot analysis to investigate the expression of these subunits in an AdCC cell line (ACCS) and a more aggressive subline (ACCS-M)...

Adenoid cystic carcinoma (ACC) is one of the common malignant tumors in salivary glands, and the clinical prognosis is poor with frequent distant metastasis which may lead to death. Expression of the MYB-NFIB chimeric gene in ACC has been reported recently. MYB is an oncogene with transcription regulating functions, and NFIB encodes nuclear transcription factor although detailed functions are unknown. This study investigated whether MYB-NFIB chimeric gene expression affects tumor angiogenesis and proliferation in salivary gland ACC...

A patient with a history of adenoid cystic carcinoma of the nasal cavity presented himself with bone pain and an elevated PSA level. On suspicion of metastatic prostate cancer a 68Ga-PSMA PET-CT was performed. The PET-CT showed numerous lung and non-sclerotic bone metastasis. Biopsy of a bone metastasis was performed and pathology showed adenoid cystic carcinoma instead of prostate cancer. Immunohistochemical PSMA staining of the primary tumour showed intense PSMA expression in adenoid cystic carcinoma tumour cells...

BACKGROUND/PURPOSE: Basal cell adenoma (BCA) and basal cell adenocarcinoma (BCAC) are uncommon salivary gland tumors comprising proliferation of basaloid cells. Nuclear β-catenin expression and mutations in its encoding gene (CTNNB1) are reported to be specific to BCA. PIK3CA mutations are only found in BCAC not in BCA. However, in previous studies the number of cases was relatively small. The present study analyzed 44 cases of basal cell neoplasms to identify the CTNNB1 and PIK3CA mutation profiles in this rare salivary gland tumor...
