Purpose: To identify potential biomarkers of salivary gland adenoid cystic carcinoma to further understand the potential pathogenesis of adenoid cystic carcinoma.
Methods: Two microarray datasets (GSE59701, GSE88804) were downloaded from NCBI GEO database. LIMMA software package was used to screen SACC differentially expressed genes. WGCNAs were used to find the important module genes that were most associated with SACC. Two machine learning methods(LASSO and SVM-RFE) were used to identify Hub genes. Subsequently, ROC curve used to predict SACC was developed to determine the diagnostic effect. R4.2.1 software was used for statistical analysis.
Results: Three hub genes(GABBR1, EN1 and LINC01296) were identified, and a ROC curve with high predictive performance (AUC, 1.000-1.000) was established.
Conclusions: Three hub genes(GABBR1, EN1 and LINC01296) were obtained by WGCNA, LASSO, SVM-RFE as potential biomarkers of SACC, and the findings of this study provide a foothold for future research on potential key genes of SACC, and a target basis for the early diagnosis and treatment of SACC.

Adenoid cystic carcinoma (ACC) is a relatively uncommon tumor among head and neck cancers, with laryngeal involvement, typically subglottic, being exceptionally rare. While ACC usually originates in the salivary glands, its occurrence in the larynx is highly unusual. Laryngeal adenoid cystic carcinoma (LACC) is characterized by indolent growth, frequent perineural invasion, and a tendency for local recurrence.

Primary cutaneous adenoid cystic carcinoma (PCACC) isa rare skin malignancy first reported in the 1970s with limited number of cases found in the literature. These neoplasms are typically identified in middle-to-older-age individuals and are mostly located in the scalp and neck region but can identified throughout the body. We describe the case of a 67-year-old male patient that presented to our department with a slow-growing nodule in the left gluteal region that turned out to be a PCACC and analyze the differential diagnosis, radiology, histopathological findings and successful treatment with a wide local excision.

Adenoid Cystic Carcinoma - ACC is a common neoplasm in major and minor salivary glands with a high risk of metastasis. Thus, the objective of the present study was to perform an analysis to better understand the histological grading systems of the ACC and its influence on tumor prognosis in terms of overall survival, disease-free and metastasis-free. This is a systematic review, with meta-analysis, based on the PRISMA parameters.

Multiple studies have demonstrated a significant association between glucose transporter-1 (GLUT1) and the development and recurrence of adenoid cystic carcinoma (ACC). In this study, we investigated the impact of GLUT1 knockdown on adenoid cystic carcinoma. Our findings revealed that hypoxic conditions promoted the progression and autophagy of SACC83 and SACC-LM cell lines, an effect that was mitigated by GLUT1 knockdown.
