The aims of this doctoral thesis were to characterize patients with recurrent respiratory papillomatosis (RRP) in northern Sweden, including voice quality and quality of life, evaluate the incidence of tonsillar cancer longitudinally in northern Sweden and to study the correlation between human papillomavirus (HPV), its surrogate marker p16 and HPV receptor syndecan-1 in tonsillar cancer and mo...

BACKGROUND As the treatment modalities for oral cancer have been relatively consistent during the last two decades, this study was conducted to compare survivals of oral cancer patients in Khon Kaen Province before and after the universal coverage scheme (UC) was launched in Thailand. MATERIALS AND METHODS The data were retrieved from the populationbased cancer registry of Khon Kaen for oral ...

BACKGROUND Germline mutations at the INK4a/p16 locus are implicated in several human cancer syndromes, including familial atypical multiple mole melanoma (FAMMM) syndrome, FAMMM-pancreatic cancer (FAMMM-PC) syndrome, and in familial head and neck cancer syndrome. METHODS We present an individual with a family history of melanoma and pancreatic cancer who had multiple dysplastic nevi, squamous...

Xenobiotic metabolism in oral tissues, especially in the tongue, has never been reported. In the present study, the metabolic activation/detoxification ability of promutagens in the tongue and the expression levels of related enzymes were investigated. Quantitative PCR analysis of rat tongue demonstrated constitutive messenger RNA (mRNA) expression of numerous drug-metabolizing enzymes. In part...

PURPOSE We report our study on two patients to highlight the risk of underdosage of the clinical target volume (CTV) due to edema during high-dose-rate interstitial brachytherapy (HDR-ISBT) of mobile tongue cancer. MATERIAL AND METHODS To treat the lateral side of the CTV, flexible applicator tubes were implanted on the mouth floor. Two-dimensional planning was performed using X-ray images fo...

Visual inspection of the tongue has been an important diagnostic method of Traditional Chinese Medicine (TCM). Clinic data have shown significant connections between various viscera cancers and abnormalities in the tongue and the tongue coating. Visual inspection of the tongue is simple and inexpensive, but the current practice in TCM is mainly experience-based and the quality of the visual ins...

The radial forearm free flap (RFFF) is a thin and pliable tissue with many advantages for tongue reconstruction. However, tongues reconstructed with RFFF occasionally need revision surgery because inadequate defect measurement at primary surgery can lead to bulkiness and limited movement of reconstructed tongue. In this case, the patient underwent partial glossectomy and RFFF reconstruction for...

Background and objective:  Oral tongue Squamous Cell carcinoma (SCC) commonly involves males between the sixth to eighth decades of life. Major risk factors are tobacco usage and alcohol consumption. The increasing number of patients developing oral tongue cancer without these well-known risk factors suggests that a viral infection, such as Human Papil...
