Oncological Feasibility of Limited Neck Dissection in cN0 Supraglottic Laryngeal Cancer.

Background: Supraglottic squamous cell carcinoma (SCC) is a significant portion of head and neck cancers, with the management of clinically negative necks (cN0) through selective neck dissection (SND) being debated due to potential morbidities and low metastasis rates in levels IIb and IV.

It analyzed occult metastasis rates and explored relapse occurrences alongside potential predictors of lymph node metastasis.

The Impact of Genetic Polymorphisms on Genotoxicity (DNA Damage) Induced by Cigarette Smoke in Humans: A Systematic Review.

The present systematic review aims to put together human population studies that include some relationship between genetic polymorphisms and genotoxicity as well as to evaluate the quality of the published studies induced by cigarette smoke exposure in vivo. The present systematic review was built according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria. Different genotoxicity assays were used by different authors, although the major goal was the genotoxicity assessment by means of micronucleus, comet, sister chromatid exchange, and chromosomal aberration assays.

Mucoepidermoid microcarcinoma in the context of parotid gland cyst.

Mucoepidermoid carcinoma is a type of salivary gland cancer that can develop in the context of a parotid gland cyst. This type of tumor is composed of mucous, epidermoid, and intercalated cells, and usually presents as a slow-growing and painless mass. A parotid gland cyst is a condition in which a fluid-filled sac forms in the parotid gland.

Latin American Consensus on the Treatment of Head and Neck Cancer.

Head and neck squamous cell carcinoma (HNSCC) is well known as a serious health problem worldwide, especially in low-income countries or those with limited resources, such as most countries in Latin America. International guidelines cannot always be applied to a population from a large region with specific conditions. This study established a Latin American guideline for care of patients with head and neck cancer and presented evidence of HNSCC management considering availability and oncologic benefit.

Prognostic Value of Hematological Parameters in Oral Squamous Cell Carcinoma.

Introduction: Oral squamous cell carcinoma (OSCC) remains a significant public health concern. The variables utilized to determine appropriate treatment for this disease also represent its most unfavorable prognostic factors, with these parameters solely determined by the neoplasm and its behavior. However, a lack of well-established indices is evident in the literature that specifically relate to the patient and indicate a worse prognosis.
