Development and Characterization of a Three-Dimensional Organotypic In Vitro Oral Cancer Model with Four Co-Cultured Cell Types, Including Patient-Derived Cancer-Associated Fibroblasts.

Cancer organoids have emerged as a valuable tool of three-dimensional (3D) cell cultures to investigate tumor heterogeneity and predict tumor behavior and treatment response. We developed a 3D organotypic culture model of oral squamous cell carcinoma (OSCC) to recapitulate the tumor-stromal interface by co-culturing four cell types, including patient-derived cancer-associated fibroblasts (PD-CAFs). : A stainless-steel ring was used twice to create the horizontal positioning of the cancer stroma (adjoining normal oral mucosa connective tissue) and the OSCC layer (surrounding normal oral mucosa epithelial layer).

Treatment strategies for patients over 80 years of age with oral squamous cell carcinoma.

Objective: To analyze the clinical characteristics of patients with oral squamous cell carcinoma aged ≥80 years, focusing on surgical treatments.

Study Design: We reviewed patients with oral squamous cell carcinoma aged ≥80 years who underwent surgery between 2005 and 2018. Basic information, comorbidities, multiple primary cancers, initial treatment, complications, and outcomes were evaluated.

Short-Term Follow-up of Surgical Management Verruca Vulgaris with Modified Estlander Flap: A Case Report and Recent Literature Review.

Background: Verruca vulgaris (VV), widely known as warts, is a common benign skin lesion, which is caused by human papilloma virus. In some cases, VV can be developed within the oral cavity. Surgical excision is considered as the most preferred treatment modality for both cutaneous and oral VV which could be challenge to deal with.

Targeting CD36-Mediated Lipid Metabolism by Selective Inhibitor-Augmented Antitumor Immune Responses in Oral Cancer.

The fatty acid receptor CD36 is expressed on various malignant cells and is suggested to contribute to tumor progression. CD36 is also expressed by several immune cells and involved in immune responses and may be a potential target in cancer immunotherapy. In this study, we investigated whether the selective inhibition of CD36 can inhibit tumor progression and facilitate an antitumor immune response in oral squamous carcinoma cells (OSCCs).
