Objectives: The present study was made in order to find possible prognostic factors in oral squamous cell carcinoma, given that it is a frequent disease (3-4% of all malignant tumors) and is the cause of a high morbidity and mortality which justifies any attempt to contribute something towards the understanding of this pathology.
Study Design: 81 oral squamous cell carcinomas, treated with the same procedure, and retrieved from the archive of the Hospital Universitario Marqués de Valdecilla (Santander) were studied. Flow cytometry was carried out on 67 of the samples.
Results: No statistically significant differences were found between the cellular proliferative index and the mitotic index, ploidy and the S-phase factor. Likewise, none of the cytometric variables studied presented any association with the appearance of local relapse, distant metastases or survival.
Conclusions: These variables cannot be used as a prognostic factors in squamous cell carcinomas of the oral cavity.

Purpose: National Comprehensive Cancer Network Guidelines recommend initiating postoperative radiation therapy (PORT) within 6 weeks of surgery for patients with head and neck squamous cell carcinoma (HNSCC), but delays affect 50% of patients, disproportionately burden minoritized groups, and contribute to worse oncologic outcomes. This trial evaluates the efficacy of Navigation for Disparities and Untimely Radiation thErapy (NDURE), an enhanced navigation-based intervention, relative to usual care (UC) patient navigation for starting timely PORT.
Methods: Adults with locally advanced HNSCC planning to undergo surgery and PORT were randomly assigned 1:1 to standard multidisciplinary head and neck oncology care and either NDURE, a multilevel navigation-based intervention to enhance key processes of care and overcome barriers to timely PORT, or UC, which consisted of standard patient navigation.

Microtubule nucleation is important for microtubule organization in dendrites and for neuronal injury responses. The core nucleation protein, γTubulin (γTub), is localized to dendrite branch points in Drosophila sensory neurons by Wnt receptors and scaffolding proteins on endosomes. However, whether Wnt ligands are important is unknown.

High glucose milieu in diabetes induces proximal tubular epithelial cells in the kidney to undergo hypertrophy and matrix protein expansion via Akt/mTORC1 signaling, leading to renal fibrosis. The familial Parkinson's disease protein DJ-1 acts as a driver of Ras-dependent tumorigenesis and protects dopaminergic neurons from apoptosis. But its function and mechanistic basis to regulate renal fibrosis is not clear.

The study explores the development and characterization of lymph node stromal cell cultures (LNSCs) from patients with oral squamous cell carcinoma (OSCC), highlighting the importance of understanding tumor-node cross-talk for effective prognostic and therapeutic interventions. Herein, we describe the development and characterization of primary lymph node stromal cells (LNSCs, N = 14) from nodes of metastatic and non-metastatic OSCC patients. Primary cultures were established by the explant method from positive (N + ; N = 2), and negative nodes (N0; N = 4) of the metastatic patients (N = 3) as well as negative (N0; N = 8) nodes from non-metastatic (N = 4) patients.

Radiation therapy (RT) is fundamental to the fight against cancer because of its exceptional ability to target and destroy cancer cells. However, conventional radiation therapy can significantly affect the adjacent normal tissues, leading to fibrosis, inflammation, and decreased organ function. This tissue damage not only reduces the quality of life but also prevents the total elimination of cancer.
