Pesticide Exposure and Head and Neck Cancers: A Case-Control Study in an Agricultural Region

Introduction: Causes of head and neck cancers (HNCs) are multifactorial, and few studies have investigated the association between chemical exposure and HNCs. The objective of this study was to investigate associations between HNCs, agricultural occupations, and pesticide exposure. The potential for the accumulation of pesticides in the adipose tissue of patients was also investigated.   Materi...

Dental caries and head and neck cancers.

IMPORTANCE Dental caries is the demineralization of tooth structures by lactic acid from fermentation of carbohydrates by commensal gram-positive bacteria. Cariogenic bacteria have been shown to elicit a potent Th1 cytokine polarization and a cell-mediated immune response. OBJECTIVE To test the association between dental caries and head and neck squamous cell carcinoma (HNSCC). DESIGN, SETT...

Exosomes, microvesicles, and head and neck cancers

The function of exosomes and microvesicles (MVs) in human tumors has been demonstrated to be important. They play important roles in the onset and development of different cancers, and have been shown to be promising objects in studies seeking to discovery and identify tumor markers. However, research on the biological activity and molecular function of MVs in head and neck cancers (HNCs) is un...

Xenograft models of head and neck cancers

Head and neck cancers are among the most prevalent tumors in the world. Despite advances in the treatment of head and neck tumors, the survival of patients with these cancers has not markedly improved over the past several decades because of our inability to control and our poor understanding of the regional and distant spread of this disease. One of the factors contributing to our poor underst...
