Biomarkers involved in the proliferation of the odontogenic keratocyst, glandular odontogenic cyst and botryoid odontogenic cyst.

Introduction: Odontogenic cysts are a heterogeneous group of lesions with varied clinical behavior.

Objective: To analyze the expression of the epidermal growth factor receptor (EGFR), Cyclin D1, and transcription factor SOX2 in the odontogenic epithelium evaluating the cell cycle control and cystic expansion.

Methods: This was a cross-sectional study including 40 cases, 20 odontogenic keratocysts (OKC), 10 botryoid odontogenic cysts (BOC), and 10 glandular odontogenic cysts (GOC).

Five-year survival and prognostic factors for oropharyngeal squamous cell carcinoma: retrospective cohort of a cancer center.

Introduction: Oropharyngeal cancer is characterized by high morbidity and mortality. Prognostic factors for this cancer are therefore useful to predict overall survival and may provide additional therapeutic targets.

Objective: To evaluate the 5-year overall survival and prognostic factors for oropharyngeal squamous cell carcinoma.

Langerhans Cells Correlate With Macrophages for Defense Mechanisms in the Atrophic Epithelium of Radicular Cysts.

Langerhans cells (LCs) play important roles in cell-mediated immune reactions, as well as in the pathogenesis of periapical lesions. The aim of this study is to evaluate the role of LCs in the proliferative epithelium of radicular cysts (RCs) and the release of the proinflammatory cytokine tumor necrosis factor α (TNF-α) associated with epithelial thickness. Thirty cases of RCs and 30 cases of residual RCs were randomly selected.
