A case-control epidemiologic study was conducted to determine the relationship between quantities and types of tobacco and the risk of cancers of individual sites within the head and neck. Substantial variations were found to exist in the tobacco-associated risk for each site. The use of cigarettes

OBJECTIVE To determine risk for oral cancer in Puerto Rico associated with use of alcohol and tobacco. METHODS In Puerto Rico, alcohol and tobacco use were compared among nonsalivary gland cancers of the mouth and pharynx (n = 342), cancers of major and minor salivary glands (n = 25) and 521

OBJECTIVE Epidemiological studies on the risk factors for salivary gland cancers (SGC) are rare, concern a small sample size, and show inconsistent results. The aim of the present work was to analyze several risk factors for SGC, using the data from the ICARE study, a multicenter, population-based

BACKGROUND Salivary gland cancer (SGC) is a rare disease with a largely unknown origin. Because cancer of the tongue and mouth floor is caused primarily by smoking and alcohol consumption, we investigated the role of tobacco, alcohol, and other possible risk factors in the development of SGC in a

Unlike most upper aerodigestive tract cancers, salivary gland cancers are relatively infrequent, are characterized by a diversity of histologic subtypes, and have never been etiologically associated with tobacco exposure. We present the results of a case-control study of risk factors for these

BACKGROUND Because existing data regarding the relation between smoking and salivary gland tumors are sparse, tobacco is currently not classified as a salivary gland carcinogen. The objective of the current study was to assess the association between smoking and benign and malignant parotid gland

Adenomatoid hyperplasia is a rare cause of swelling of the oral minor salivary glands, but is of significance because of its clinical resemblance to salivary gland tumors. The histologic appearance is one of benign hyperplasia and hypertrophy of the minor mucous glands. The clinical and histologic

Warthin's tumor is a relatively uncommon salivary gland neoplasm, traditionally considered a disease of men. Recent reports have brought this assumption into question by identifying a substantial percentage of patients who are women. Furthermore, several reports have attempted to correlate cigarette

Of the 10 539 cases of cancer recorded in the Kuwait Cancer Registry in the 10 years 1979-1988, 784 (7.4%) involved the lip, oral cavity or pharynx. Nearly half of these were of the nasopharynx or salivary glands, and the incidence of salivary gland cancer appears to be increasing. The aetiology may

Warthin's tumour has traditionally had a strong male association, and has been said to be rare in Blacks. Current studies describe a new trend; a rise in females, strongly linked to cigarette smoking. The tumour has eosinophilic epithelial cells packed with distinctive mitochondria, and a lymphoid

The value of population screening for oral cancer among male adults as a method of oral cancer control is an issue of great controversy. Screening programs have different objectives, varying costs, undocumented benefits, and some may have harmful effects. Consequently, these programs are not

: The overall incidence of head and neck cancer-which includes laryngeal, hypopharyngeal, nasal cavity, paranasal sinus, nasopharyngeal, oral, oropharyngeal, and salivary gland cancers-has declined in the United States over the past 30 years with the concomitant reduction in tobacco use. Over that

Patients diagnosed in Connecticut from 1935 to 1982 with cancers of the tongue, gum, floor, and other parts of the mouth, or pharynx experienced twofold to threefold increased risks of developing a second primary cancer. The excesses were most prominent [relative risk (RR) greater than or equal to

Cancers of the buccal cavity and the pharynx are not only anatomically related but, except for the nasopharynx, also have risk factors in common. Multifocal occurrence of cancers in the buccal cavity and pharynx must be kept in mind when one is interpreting findings on multiple tumors. However,

Few studies of the occupational etiology of cancer have focused upon the risks that women experience in the workplace. In this case-referent study of 11 cancer sites (lung, colon, rectum, bladder, esophagus, liver, salivary gland, stomach, eye, melanoma of the skin, mesothelioma), 7686 women in the
