Frequent detection of high human papillomavirus DNA loads in oral potentially malignant disorders

Oral Cancer and Oral Potentially Malignant Disorders

Predictive value of dysplasia grading and DNA ploidy in malignant transformation of oral potentially malignant disorders.

Dysplasia grading is widely used to assess risk of transformation in oral potentially malignant disorders despite limited data on predictive value. DNA ploidy analysis has been proposed as an alternative. This study examines the prognostic value for both tests used in a routine diagnostic setting to inform clinical management. A retrospective study of conventional dysplasia grading was conducte...

Oral potentially malignant disorders: Is malignant transformation predictable and preventable?

Leukoplakia is the most common potentially malignant disorder of the oral mucosa. The prevalence is approximately 1% while the annual malignant transformation ranges from 2% to 3%. At present, there are no reliable clinicopathological or molecular predicting factors of malignant transformation that can be used in an individual patient and such event can not truly be prevented. Furthermore, foll...

Absence of Human Papillomavirus in Benign and Malignant Breast Tissue

Background & Objective: Malignant breast tumors, which are one of the most important deadly cancers in women, like many other cancers, are proposed to be related to viruses etiologically. Proper management of breast carcinoma necessitates an identification of the etiological factors. Human Papillomavirus is considered to have an etiological role in breast carcinoma. We...

quantitative immunoexpression of egfr in oral potentially malignant disorders: oral leukoplakia and oral submucous fibrosis

background and aims. many oral squamous cell carcinomas develop from potentially malignant disorders (pmds) which include a variety of lesions and conditions characterized by an increased risk for malignant transformation. this study evaluated the quantitative expression of egfr in normal oral mucosa, oral leukoplakia and oral submucous fibrosis to predict the malignant risk in compliance with ...
