SUMMARYCarcinogenicity tests showed that addition of the antioxidant BHA to the diet of F rats induced high incidences of papilloma and squamous cell carcinoma of the forestomach of both sexes. Male hamsters given BHA for 24 weeks also developed papilloma showing downward growth into the submucosa of the forestomach. These results indicate that BHA should be
An investigation was performed to evaluate the feasibility of a study of bladder cancer incidence or mortality at a small chemical facility in southern Michigan where workers were subject to exposure to 4,4'-methylenebis(2-chloroaniline) () (MBOCA). In order to investigate the relationship between tobacco smoking, occupations, and altered patterns of p53 expression, we have analyzed a group of incident patients with superficial

In the Dyestuffs Group of the Association of British Chemical Manufacturers organized and financed a Papilloma of the bladder in the chemical industry book research project on industrial papilloma of the bladder with special reference to the dyestuffs industry.
At the outset the scheme was to be focused on 3 suspected compounds-alpha-naphthylamine, beta-naphthylamine and benzidine.

Bladder Cancer represents the 6th most common cancer diagnosis inaccounting for % of all new cancer cases .Around 70% of new diagnoses represent Non-Muscle Invasive Bladder Cancer (NMIBC), of which 10% are CIS .The untreated natural history of CIS is progression to Muscle Invasive Bladder Cancer (MIBC) in 50% of cases at 5 years .
A review is presented of 66 cases of bladder tumours occurring among workers in a factory where aniline dyes are prepared; 23 affected men were exposed only to benzidine; 15 had worked solely on beta naphthylamine. Others had been exposed to several substances. The processes followed in the manufacture of benzidine and beta naphthylamine are outlined; the latter dye is no longer After a short discussion of occupational cancer in general, the authors give a table classifying industrial.

Urothelial papilloma is a benign exophytic urothelial neoplasm that typically occurs in patients younger than 50 years of age. 6 The male-to-female ratio is 2: 1.
The most common symptom is hematuria. 6 Most tumors are located near the ureteric orifices. Urothelial papilloma may recur, but recurrent papilloma does not progress. 6,7 Genetic Factors. The genetic factors associated with bladder cancer development can be categorized into familial history, genetic polymorphism, phenotypes of acetyltransferase, activation and mutation of oncogenes and tumor suppressor genes (TSG), and chromosomal changes.
Oncogenes associated with bladder cancer include those of the RAS gene family, including the p21 RAS The whole-life occupational histories of 1, patients ( men and women) with papilloma and carcinoma of the bladder were analyzed.

As early as — long before any clues to the etiology of tumors in other organs were apparent — Rehn reported his observations of the increased occurrence of tumors of the urinary bladder in laborers who had daily contact with basic fuchsin over a long period.
He suspected a causal connection between aniline, nitrobenzol, toluidine, and basic fuchsin and the development of the The frequency of bladder cancer in workers exposed to dyes is relatively high, although the exact number of cases in each industry in which exposure to such dyes occurs is difficult to determine.
The total number of occupa- tional bladder cancers reported since Rehn's 39 initial observations is estimated by Lock- wood M to be 2,() Epidemiology. Worldwide in, new cases of bladder cancer were diagnosed anddeaths occurred. 1 The majority of bladder cancers occur in males; bladder cancer is the sixth most common cancer in men and the seventeenth most common cancer in women.
