Molecular targeted therapy, advanced treatment for cancers of the head-and-neck region: A systematic review.

Introduction: The foundation of oncology treatment as a single modality approach as well as the "multimodality" concept has been studied by statistical evaluation pre, during, and posttreatment to rule out their efficacy, expected prognosis, toxicity reactions, and overall survival for the patient. Such studies have also provided an appreciable amount of data for future custom utility. "Targeted therapy" is a cancer treatment that uses drugs but is different from traditional chemotherapy.

Evaluation of total glutathione-s-transferase levels in serum of patients with oral malignancy.

Introduction: Squamous cell carcinoma-related antigen is not always sensitive enough for the early detection of oral cancer which is why a new marker has been desired as a substitute to be applied for serum diagnosis of oral cancer. Reactive oxygen species (ROS) has been known to play an important role in carcinogenesis. Glutathione-s-transferases (GSTs) are a family of eukaryotic and prokaryotic phase-II metabolic isoenzymes involved in xenobiotic detoxification.

Implementation of meta-analysis approach, comparing conventional radiotherapy, and proton beam therapy treating head and neck cancer.

Introduction: Radiation therapy is commonly used in the treatment of head and neck cancer in both the definitive and postoperative settings. Proton therapy, due to its intrinsic physical properties, has the ability to reduce the integral dose delivered to the patients while maintaining highly conformal target coverage.
