Objectives: To determine the expression of the c-erb-B2, p53, bcl-2, Ki67 and CD44varV6 proteins, and to establish their prognostic value in epidermoid carcinoma of the lip.
Study Design: Immunohistochemical study of the c-erb-B2, p53, bcl-2, Ki67 and CD44varV6 proteins in 79 epidermoid carcinomas of the lip, diagnosed and treated over a period of 20 years. The data obtained were subjected to uni- and multi-variate statistical analyses.
Results: Immunostaining was positive in 75% of cases for c-erb-B2 protein, in 70.6% for p53 protein, in 3.8% for bcl-2 protein and in 89.9% for adhesion molecule CD44varV6. Ki67 protein expression varied between a minimum of 0% and a maximum of 6.29%. Most immunohistochemical factors analyzed presented no prognostic value for epidermoid carcinoma of the lip. Only those patients affected by this type of tumor that expressed the adhesion molecule CD44varV6 were significantly associated with a greater survival calculated by means of Kaplan-Meier analysis.
Conclusions: The immunohistochemical techniques analyzed for the anatomicopathological study of epidermoid carcinoma of the lip should not routinely be used due to their high cost and low utility in daily clinical practice.

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.

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.

Objective: To investigate the clinical manifestations of head and neck cancer in patients with Plummer-Vinson syndrome (PVS) and to assess related oral comorbidities.
Materials And Methods: Case reports covering head and neck cancer manifestations in patients diagnosed with PVS were included Studies were identified through seven main electronic databases (PubMed/MEDLINE, EMBASE, Scopus, Web of Science, CINAHL, LILACS, and LIVIVO), and a search for gray literature was performed using ProQuest Dissertations and Theses and Google Scholar. Independent reviewers applied predefined eligibility criteria in a two-phase selection process.
Objective: This study aims to compare the effectiveness of 2 artificial saliva substitutes (Biotène vs HydraSmile) in the symptomatic management of radiation-induced xerostomia.
Study Design: Randomized double-blind cross-over study.
Setting: Single tertiary care academic institution.
