The role of cytopathology in diagnosing HPV induced oropharyngeal lesions.
ABSTRACT HPV detection in fine needle aspirates from suspected head and neck metastasis may be useful in clinching the diagnosis of HPV related oral squamous cell carcinoma. Ascertaining the HPV status of a particular tumor on cytological specimens could be useful for prognostication as HPV-related tumors appear to have a better prognosis and clinical outcome. The various techniques of detection are reviewed.

ABSTRACT: A case-control study of oral and pharyngeal cancer conducted in four areas of the United States provided information on the tobacco and alcohol use of 1114 patients and 1268 population-based controls. Because of the large study size, it could be shown that the risks of these cancers among nondrinkers increased with amount smoked, and conversely that the risks among nonsmokers increased with the level of alcohol intake. Among consumers of both products, risks of oropharyngeal cancer tended to combine more in a multiplicative than additive fashion and were increased more than 35-fold among those who consumed two or more packs of cigarettes and more than four alcoholic drinks/day. Cigarette, cigar, and pipe smoking were separately implicated, although it was shown for the first time that risk was not as high among male lifelong filter cigarette smokers. Cessation of smoking was associated with a sharply reduced risk of this cancer, with no excess detected among those having quit for 10 or more years, suggesting that smoking affects primarily a late stage in the process of oropharyngeal carcinogenesis. The risks varied by type of alcoholic beverage, being higher among those consuming hard liquor or beer than wine. The relative risk patterns were generally similar among whites and blacks, and among males and females, and showed little difference when oral and pharyngeal cancers were analyzed separately. From calculations of attributable risk, we estimate that tobacco smoking and alcohol drinking combine to account for approximately three-fourths of all oral and pharyngeal cancers in the United States.Cancer Research 07/1988; 48(11):3282-7. · 8.65 Impact Factor

ABSTRACT: In a previous article, we reported the prevalence rates of oral mucosal lesions in this hospital from 1990-2001. This study was planned to study the spectrum of potentially malignant and malignant oral lesions in Allahabad, North India in the subsequent years till 2007 and to assess change in pattern of prevalence, if any. This is a single institutional retrospective study in and around Allahabad from 1990 to 2007. Data was collected year wise with reference to age, sex, site involved and histopathological findings. 1,151 oral biopsies were reviewed. Of these, 365 biopsies were benign, 344 were potentially malignant and 442 were malignant. The buccal mucosa was the most frequently involved site in benign and premalignant lesions, however in malignant lesions, the tongue was most common site. Oral submucous fibrosis constituted the highest number of patients in premalignant group, while in malignant group, squamous cell carcinoma was most prevalent. This study showed that potentially malignant and malignant oral lesions were widespread in the patients visiting the hospital in this region.Asian Pacific journal of cancer prevention: APJCP 9(2):263-5. · 1.50 Impact Factor
