Available statistics on smoking, alcohol, food supply, reproductive history, and other lifestyle habits from the U.S. and Italy were compared and related to mortality rates of common neoplasms over the period 1955 to 1980. Per capita cigarette consumption has declined in the U.S. since the early 1960s but continues to rise in Italy, chiefly due to the recent increase in cigarette smoking among ...

Cytokeratin (CK) 20, Ki-67, and p53 were applied to 84 noninvasive papillary urothelial tumors graded by the 1973 World Health Organization (WHO) and 1998 WHO/International Society of Urological Pathology (ISUP) systems. In the WHO/ISUP classification, all benign lesions showed normal CK20 staining and all carcinomas showed abnormal staining. The Ki-67 index was significantly different between ...

Data for adults with cancer were provided by 107 population-based cancer registries from 29 countries grouped into five regions: Denmark, Finland, Iceland, Norway, Sweden (northern Europe); England, Ireland, Northern Ireland, Scotland, Wales (UK and Ireland); Austria, Belgium, France, Germany, Netherlands, Switzerland (central Europe); Croatia, Italy, Malta, Portugal, Slovenia, Spain (southern ...

A significant dose-response relation between ingested arsenic and several cancers has recently been reported in four townships of the endemic area of blackfoot disease, a unique peripheral artery disease related to the chronic arsenic exposure in southwestern Taiwan. This study was carried out to examine ecological correlations between arsenic level of well water and mortality from various mali...

OBJECTIVES To examine the recent epidemiological evidence on cancer risk among workers in the rubber industry. METHODS Epidemiological studies published after the last detailed review by the International Agency for Research on Cancer (IARC) in 1982 were reviewed. 12 cohort studies in nine countries that examined distinct populations of workers in the rubber industry, seven industry based nes...

Recent reports by Bielschowsky (1), Harris (6), Engel and Copeland (5), Strombeck and Ekman (10), and Morris et al. (7), indicate that the genetic constitution of the rat plays a more dominant role than diet in the initiation of 2-acetylaminofluorene-induced neoplasms. While liver tumors occur in a majority of the rats and the frequency is altered somewhat by the protein content of the diet, th...

Second malignant neoplasms were evaluated among 32,251 women with ovarian cancer, including 4,402 10-year survivors, within the nine population-based registries of the Surveillance, Epidemiology, and End Results Program of the National Cancer Institute (1973-1992) and the Connecticut Tumor Registry (1935-1972). Overall, 1,296 second cancers occurred against 1,014 expected [observed/expected (O/...

Background: Non-muscle invasive bladder neoplasms with invasion of the lamina propria (stage T1) or high grade of dysplasia are at “high risk” of progression to life-threatening cancer. However, the individual course is difficult to predict. Chromosomal instability (CI) is 5 associated with high tumor stage and grade, and possibly with the risk of progression. Methods: To investigate the relati...

To compare the detection of bladder neoplasms and image quality among the diffusion-weighted imaging (DWI) acquired by the prototype single-shot echo-planar-imaging (ss-EPI) sequence for integrated slice-specific dynamic shimming (iShim), readout segmentation of long variable echo trains (RESOLVE) and conventional ss-EPI sequences.Around 63 patients with 77 bladder lesions were enrolled. The MR...
