In a retrospective study, interviews were obtained with 3,716 patients with histologically proven cancer of the lung (Kreyberg types I and II), mouth, larynx, esophagus, or bladder and with over 18,000 controls. For each of these cancers, the relative risk of both male and female present smokers increased with the quantity smoked and the duration of the habit. The strongest increase occurred for cancer of the lung and larynx, and the least increase occurred for cancer of the esophagus and bladder. For exsmokers the risk decreased with years of cessation. The risk for mouth cancer of pipe and cigar smokers who inhaled much less than cigarette smokers was less than that of the latter and increased with the quantity smoked. The risk of mouth, larynx, and esophagus cancer among smokers increased with the quantity of alcohol consumed. Greater smoking habits and lesser cessation rates were noted among lower socioeconomic groups, suggesting that these groups will bear an ever increasing proportion of the burden of tobacco-related cancer.

In a hospital-based case-control study, 290 oral cancer cases and 133 esophageal cancer cases were queried as to smoking status, alcohol consumption, and dietary exposures, including vitamin supplement history. Among oral cancer cases, vitamin E use appeared to exert a protective effect. Vitamins C and E had protective effects among esophageal cancer cases. When stratified by smoking status, the protective effect of vitamin C use in esophageal cancer was significant only among current smokers, as was vitamin B use. A reduced risk of oral cancer was correlated with multivitamin use and increasing vegetable consumption, as was vegetable/fruit consumption and vitamin C supplementation. Among esophageal cancer cases, increasing meat consumption and vitamin C use were associated with a significantly reduced cancer risk.

The relationship between maize consumption and risk of cancer of the upper digestive tract was investigated in 107 patients with oral cancer, 107 with pharyngeal cancer, 68 with esophageal cancer, and 505 hospital controls who permanently resided in Pordenone Province in the northeastern part of Italy. The analysis was restricted to males. The population of this province has a high incidence of these neoplasms and shows particularly elevated levels of alcohol and tobacco use, in addition to high maize consumption. Highly significant associations with frequent intake of maize emerged for oral cancer, pharyngeal cancer, and esophageal cancer (odds ratios = 3.3, 3.2, and 2.8, respectively). The risk elevation could not be explained in terms of differences in education, occupation, tobacco use, or consumption of fresh fruits and vegetables. The unfavorable effect of maize on risk of cancer of the upper digestive tract, however, was evident only in those individuals who reported heavy drinking (i.e., greater than or equal to 42 alcoholic drinks/wk). The present findings are likely to be related to the fact that maize can cause deficiencies of various micronutrients (chiefly, niacin and riboflavin) and agree with previous observations from Africa, the People's Republic of China, the United States, and Italy.

Mouse monoclonal antibody (MAb) 3F8E3 (IgG3k) was developed against the head and neck cancer cell line LICR-LON-HN2. Subjected to indirect immunofluorescence, the MAb reacted exclusively with SCC cell lines and showed no reactivity with normal or transformed mouse and human non-SCC cell lines and hematopoietic cell lines. The radiolabelled MAb showed an affinity constant of 1.8 x 10(8) M-1 with HN2 cells and identified 2.07 x 10(4) sites/cell by Scatchard analysis. It identified 2 peptides from membrane extracts of HN2 cells by Western blotting. Avidin-biotin-complexed immunoperoxidase staining on cryostat sections of tumors from various tissues revealed that 3F8E3 reacted mainly with the membrane antigens of well differentiated SCC cells of oral cavity, larynx, esophagus, lung, uterine cervix, metastatic nodes of patients with oral cancer, and dysplastic cells in oral leukoplakia. The MAb did not react with poorly differentiated cells of Ca esophagus, adenocarcinoma of breast, stomach and colon, renal-cell carcinoma and soft-tissue sarcoma.

Evidence from animal studies indicates that various N-nitroso compounds are carcinogenic. We investigated whether consumption of foods and beverages containing nitrosodimethylamine, nitrites, and nitrates affected the risk of laryngeal, esophageal, and oral cancer. In a population-based case-control study in western Washington state, dietary consumption of these substances was measured in 645 cases (169 laryngeal, 125 esophageal, and 351 oral) and 458 controls. After adjustment for tobacco, alcohol, and other known risk factors, there was a 52% reduction in the risk of upper aerodigestive tract cancer for individuals who consumed higher amounts of nitrate (upper tertile) compared with the lowest tertile (P < 0.001 for trend). Nitrate intake was associated with a reduction in cancer risk at all three sites. The reduction in the risk of esophageal cancer with increasing nitrate consumption was more evident in frequent tea drinkers than in other subjects. There was no significant association between nitrite consumption and the risk of laryngeal or oral cancer. However, for individuals with a history of canker sores (an indicator of possible endogenous nitrosation), the risk of esophageal cancer was seven times greater in those with high versus low nitrite intake. Consumption of foods high in nitrosodimethylamine was associated with a 79% increased risk of upper aerodigestive tract cancer (P = 0.037 for trend). Cases consumed smoked fish more frequently than did controls [odds ratio (OR) = 3.03]. Daily intake of beer and of nitrite-containing meats were associated with an increased esophageal cancer risk (OR = 2.48 and 1.82, respectively).(ABSTRACT TRUNCATED AT 250 WORDS)

A population-based case-control study was conducted in western Washington state to investigate possible dietary risk factors for laryngeal, esophageal, and oral cancers. Using results from a food frequency questionnaire, past dietary intakes of iron, zinc, and calcium were estimated for 661 cases and 466 controls. Clippings were also taken from the nails of both halluces to determine concentrations of iron, zinc, calcium, chromium, and cobalt in 507 of the cases and 434 of the controls. After adjustment for smoking, alcohol, and dietary beta-carotene and vitamin C intake, individuals who reported dietary intakes of iron and zinc in the upper quartile were less likely to develop cancers of the larynx and esophagus than were individuals with intakes in the lowest quartile [odds ratios (OR), 0.5 for iron and 0.1 for zinc]. However, there were no significant differences in zinc concentrations in nail tissue between subjects with these types of cancer and controls. Esophageal cancer cases had higher nail concentrations of iron and calcium than did controls (OR, 2.9 for high versus low quartiles of iron; OR, 2.6 for high versus low quartiles of calcium). Individuals who developed esophageal or oral cancer were more likely to have elevated cobalt concentrations in their nail tissue than were individuals without cancer (OR, 9.0 and 1.9 respectively, for high versus low quartiles). The results of this study suggest that there may be differences in mineral intake or metabolism between individuals who develop some carcinomas of the upper aerodigestive tract and those who do not.

Using data from 59 countries, we conducted an international comparison study to identify nutritional predictors of age-adjusted oral and esophageal cancer mortality rates. Statistical models accounted for per capita tobacco disappearance data, alcohol consumption, and various measures of socioeconomic status. For oral cancer, stepwise regression results showed protective effects for milk/dairy products (B = -0.030, p < 0.0001) and cabbage consumption (B = -0.391, p = 0.01) and increased risk from vegetable oil (B = 0.072, p = 0.04) and excess animal fat calories (B = 0.344, p < 0.0001) as well as marginally increased risk from cereals (B = 0.008, p = 0.08). Results were obtained after accounting for all background factors, including sex (model R2 = 0.52). For esophageal cancer, stepwise results indicated protective effects for fruit (B = -0.046, p = 0.0006) and total caloric intake (B = -0.013, p < 0.0001) and increased risk from vegetable oil (B = 0.061, p = 0.04) and meat (B = 0.031, p < 0.0001) consumption (model R2 = 0.55). When analyzed separately by sex, results were similar, indicating that the risk factors are probably the same in both sexes, even though women consistently have fewer deaths, on average, from these cancers. On the basis of results from stepwise regression models, we also fitted general linear models for mortality rates of each cancer site, and results were similar in terms of magnitude and direction of effects. Although the evidence provided by this type of analysis using data aggregated by country is limited in terms of control for potential confounding effects and modeling of possible effect modification, an effect of high meat, animal product, or vegetable oil and low fruit and cabbage consumption is consistent with the known biology of these tumors.

Smoking--once a socially accepted behavior--is the leading preventable cause of death and disability in the United States. During the first decades of the 20th century, lung cancer was rare; however, as cigarette smoking became increasingly popular, first among men and later among women, the incidence of lung cancer became epidemic (Figure 1). In 1930, the lung cancer death rate for men was 4.9 per 100,000; in 1990, the rate had increased to 75.6 per 100,000 (1). Other diseases and conditions now known to be caused by tobacco use include heart disease, atherosclerotic peripheral vascular disease, laryngeal cancer, oral cancer, esophageal cancer, chronic obstructive pulmonary disease, intrauterine growth retardation, and low birthweight. During the latter part of the 20th century, the adverse health effects from exposure to environmental tobacco smoke also were documented. These include lung cancer, asthma, respiratory infections, and decreased pulmonary function (2).

The cyclin-dependent kinase inhibitor gene p21(Waf1/Cip1) plays a central role in inducing cellular growth arrest, terminal differentiation, and apoptosis. Alterations in this gene may adversely affect regulation of these processes and increase susceptibility for cancer. We have recently reported a novel polymorphism in the p21(Waf1/Cip1) gene in the Indian population and its association with esophageal cancer. An A-->G transition at codon 149 resulted in amino acid substitution from aspartate to glycine in the proliferating cell nuclear antigen binding COOH-terminal domain of p21(Waf1/Cip1) that may affect PCNA-p21(Waf1/Cip1) interactions, thereby affecting regulation of cellular proliferation, and may increase susceptibility for development of cancer. In a parallel study in our laboratory, we searched for putative p21(Waf1/Cip1) mutations in oral premalignant and malignant lesions. No somatic mutation was detected in exon 2 of p21(Waf1/Cip1). Interestingly, a codon 149 polymorphism variant (A-->G) was identified in 11 of 30 (37%) premalignant lesions (7 of 19 hyperplastic lesions and 4 of 11 dysplastic lesions) and 11 of 30 (37%) squamous cell carcinomas (SCCs). This codon 149 variant was also identified in paired lymphocytes of all of the patients with premalignant lesions and SCCs harboring the variant allele, suggesting the occurrence of a polymorphism. Lymphocyte DNA isolated from 50 unrelated age- and gender-matched healthy subjects was screened for this polymorphism. Seven of 50 (14%) normal controls harbored the A-->G codon 149 variant allele. Immunohistochemical analysis of p21(Waf1/Cip1) protein expression showed immunoreactivity in 19 of these 30 (63%) oral premalignant lesions and 16 of 30 (53%) SCCs. The most intriguing features of the study were: (a) the significant increase in frequency of this polymorphism not only in patients with oral SCCs (P = 0.038), but also in patients with premalignant lesions (P = 0.038), compared with normal controls; and (b) the significantly higher frequency of p21(Waf1/Cip1) variants (codon 149) in oral premalignant lesions (10 of 11 cases) and SCCs (11 of 11 cases) with wild-type p53 (P = 0.045) than in lesions with p53 mutations, suggesting that this polymorphism affects the p53 pathway and may play a vital role in oral tumorigenesis. Furthermore, overexpression of p21 protein in oral lesions harboring missense mutations in the p53 gene suggest a p53-independent role for p21 in the pathogenesis of oral cancer.

The relation between various types of fiber and oral, pharyngeal and esophageal cancer was investigated using data from a case-control study conducted between 1992 and 1997 in Italy. Cases were 271 hospital patients with incident, histologically confirmed oral cancer, 327 with pharyngeal cancer and 304 with esophageal cancer. Controls were 1,950 subjects admitted to the same network of hospitals as the cases for acute, nonneoplastic diseases. Cases and controls were interviewed during their hospital stay using a validated food frequency questionnaire. Odds ratios (OR) were computed after allowance for age, sex, and other potential confounding factors, including alcohol, tobacco consumption, and energy intake. The ORs for the highest vs. the lowest quintile of intake of oral, pharyngeal and esophageal cancer combined were 0.40 for total (Englyst) fiber, 0.37 for soluble fiber, 0.52 for cellulose, 0.48 for insoluble non cellulose polysaccharide, 0.33 for total insoluble fiber and 0.38 for lignin. The inverse relation were similar for vegetable fiber (OR = 0.51), fruit fiber (OR = 0.60) and grain fiber (OR = 0.56), and were somewhat stronger for oral and pharyngeal cancer than for esophageal cancer. The ORs were similar for the two sexes and strata of age, education, alcohol and tobacco consumption, and total non-alcohol energy intake. Our study indicates that fiber intake may have a protective role on oral, pharyngeal and esophageal cancer.
