Adenoid cystic carcinoma (ACC) is the second most common salivary gland malignancy and it has a high rate of recurrences and a poor long-term prognosis. Our aim was to assess the prognostic factors in ACC and study MYB-NFIB fusion and MYB protein expression in a large retrospective cohort of 135 patients with a median follow-up of 6.3 years. The 5- and 10-year local recurrence-free survival (RFS) rate of 94% and 78%, 5- and 10-year distant metastasis survival rate of 77% and 58%, and 5- and 10-year RFS of 66% and 44%...

Cancer progression through the mandible bone is still questioned. Once the tumor has eroded the cortex, it can extend vertically and laterally. It usually spreads in the medullary spaces and finally affects the alveolar nerve. The presence of the teeth has been considered as a relative barrier to cancer infiltration until now. Herein, we report an uncommon case of dental root invasion by adenoid cystic carcinoma of the floor of the mouth.

A 50-year-old woman presented with gradually increasing right-sided facial numbness. Neuroimaging revealed a lesion in the right cavernous sinus mimicking meningioma. The resection of the right cavernous sinus neoplasm was implemented via endoscopic endonasal approach under general anesthesia. Histological examination of the surgical specimen revealed adenoid cystic carcinoma. Adenoid cystic carcinoma in the cavernous sinus is extremely rare as a primary lesion and challenging to manage. Little data exist to guide treatment when this tumor extends to involve the structure of cavernous sinus...

Julia Thierauf, Johannes Adrian Veit, Jochen Hess
Head and neck cancer (HNC) is one of the most prevalent human malignancies worldwide, with a high morbidity and mortality. Implementation of interdisciplinary treatment modalities has improved the quality of life, but only minor changes in overall survival have been achieved over the past decades. Main causes for treatment failure are an aggressive and invasive tumor growth in combination with a high degree of intrinsic or acquired treatment resistance. A subset of tumor cells gain these properties during malignant progression by reactivating a complex program of epithelia-to-mesenchymal transition (EMT), which is integral in embryonic development, wound healing, and stem cell behavior...

BACKGROUND/AIM: Perineural invasion and distant metastasis lead to a poor prognosis of adenoid cystic carcinoma and there is no effective therapy available. MicroRNAs (miRNAs) are small non-coding RNAs that regulate target gene expression, which can be biomarkers or therapeutic targets for certain cancer types. We aimed to identify miRNAs and their target genes possibly involved in metastasis of salivary gland adenoid cystic carcinoma (SACC). MATERIALS AND METHODS: Using Nanostring nCounter analysis, we examined miRNA expression in two SACC cell lines: SACC-83 and SACC-LM, with low and high lung metastasis rates, respectively...

Primary cutaneous adenoid cystic carcinoma (ACC) is an extremely rare and indolent cutaneous malignancy with very infrequent distant metastasis. We present a case of primary cutaneous ACC with bilateral lung metastases in a 57-year-old male along with literature review. To the best of our knowledge this is the tenth case of primary cutaneous ACC reported presenting with distant metastasis.

Adenoid cystic carcinoma (ACC) is a rare cancer arising from the major or minor salivary gland tissues of the head and neck. There are currently no approved systemic agents or known radiosensitizers for ACC. Unlike the more common head and neck squamous cell carcinomas that frequently harbor TP53 mutations, ACC contain TP53 mutations at a rate of <5%, rendering them an attractive target for MDM2 inhibition. <p>Experimental Design: We report the successful establishment and detailed characterization of a TP53-WT ACC patient derived xenograft (PDX) which retained the histologic features of the original patient tumor...

Primary epithelial tumours of the salivary glands are very rare in paediatric patients. The aim of this study was to evaluate the clinical course, treatment, and outcomes of these uncommon neoplasms based on the authors' experience and the recent literature. The medical charts of 12 female patients and seven male patients with primary epithelial salivary gland tumours were reviewed. All were under 19 years of age and underwent surgical treatment between 1994 and 2016. The results of this group of paediatric patients were compared with those of 621 adult patients...

BACKGROUND: Adult hemophagocytic lymphohistiocytosis is a secondary immunopathologic phenomenon, mainly secondary to malignancy, infection, or autoimmune disorders. The performance of diagnostic criteria, studied in the pediatric population, is yet to be validated in the adult population. Some of the criteria include cytopenias and organomegaly that are inherent features to malignant processes, thus making the diagnosis of hemophagocytic lymphohistiocytosis a challenge in patients with cancer...

Adenoid cystic carcinoma of the head and neck area is a rare malignant tumor with acceptable short-term but mediocre long-term prognosis. Radical tumor excision with clear resection margins, and sometimes resection of the facial nerve due to perineural growth, remains the fundamental therapy. We present 3 distinct clinical cases and discuss the current therapeutic options with special focus on plastic-reconstructive techniques. For reconstruction, the full armament of local and free flaps, as well as prosthetics, may be necessary...

Mithramycin exhibits certain anticancer effects in glioma, metastatic cerebral carcinoma, malignant lymphoma, chorionic carcinoma and breast cancer. However, its effects on salivary adenoid cystic carcinoma remain unclear. Here, we report that mithramycin significantly inhibited epithelial-to-mesenchymal transition and invasion in human salivary adenoid cystic carcinoma cell lines. The underlying mechanism for this activity was further demonstrated to involve decreasing the expression of the transcription factors specificity protein 1 and SNAI1...

NKX2.2 is a new immunohistochemical marker that has been reported to be sensitive and specific for Ewing sarcoma (ES). It has not, however, been investigated specifically in the sinonasal small round blue cell tumor (SRBCT) differential diagnosis which includes many tumors specific to that site. It has also not been investigated in the newly recognized "adamantinoma-like" variant of ES. Immunohistochemistry for NKX2.2 was performed on 170 poorly differentiated sinonasal neoplasms: 73 squamous cell carcinomas (67 poorly differentiated, non-keratinizing, or basaloid types and 6 nasopharyngeal carcinomas), 46 olfactory neuroblastomas, 8 sinonasal undifferentiated carcinomas (SNUCs), 6 melanomas, 7 Ewing sarcomas, 6 SMARCB1-deficient carcinomas, 6 teratocarcinosarcomas, 5 alveolar rhabdomyosarcomas, 4 solid adenoid cystic carcinomas, 4 NK/T cell lymphomas, 3 NUT carcinomas, and 2 small cell carcinomas...
