Abstract
Tobacco use is the greatest threat to public health worldwide, killing more than seven million people annually. This paper, about 10 years after the first review on electronic cigarettes, analyses the evolution that this tool has had in these years. It concludes with comments on the significance of the research and why it constitutes an original contribution. We searched PubMed (National Library of Medicine), and PsycINFO (Ovid) (2006-2020) for studies on e-cigarettes (harms and benefits, e-cigarette use, craving and smoking cessation) and smoking cessation treatment (smoking cessation treatment or varenicline or tobacco cessation or reduction or bupropion or NRT or behavioral treatment or ecigarette) and evidence suggests that they may effective as smoking cessation tool and may be less harmful alternatives to combustible cigarette smoking. Consequently, e-cigarettes could be considered as an applicable instrument for Tobacco Harm Reduction (THR) and smoking cessation.

Abstract
This narrative review focuses on the topic of tobacco smoking amongst people with schizophrenia spectrum disorders. We searched PubMed, PsycInfo and Scopus databases for schizophrenia spectrum disorders and smoking and included articles about the epidemiology of tobacco smoking in people with schizophrenia spectrum disorders, examining the relationship between smoking and mental health. This narrative review describes that a higher prevalence, frequency and impact of both high nicotine dependence and its harmful effects in patients with schizophrenia spectrum disorders compared with those in the general population. Despite several existent theories, the reasons for high smoking rates, the high dependence on nicotine and severity of nicotine withdrawal symptoms are not fully understood. The main aim of this paper is to inform mental health personnel and particularly clinical and health psychologists about the impact and role of tobacco smoking for smokers with schizophrenia spectrum disorders.

Alcohol, smoking and the liver disease patient. Best Pract Res Clin Gastroenterol 2017; 31:537-543.

Abstract
Alcohol is an established risk factor for cirrhosis. Current recommendations for a "safe" limit for alcohol consumption are usually set to around 30 g of alcohol per day for men and 20 g per day for women, but evidence is mounting that these cut-offs might be set too high. Also, inter-individual differences in the hepatic sensitivity for alcohol likely play into the risk of development of cirrhosis. In patients with concomitant liver diseases, a synergistic effect on fibrosis progression and high consumption of alcohol is evident. The role of low to moderate consumption is less clear. Alcohol can also lead to a specific inflammatory state in the liver, alcoholic hepatitis (AH). Treatment of severe AH consists of corticosteroids, which are at best moderately effective, and new treatments are needed. Liver transplantation is an option in severe alcoholic liver disease, although selection of patients that are at a very low risk of post-transplantation alcohol consumption is paramount. There is some evidence to suggest an increased risk for fibrosis progression and development of hepatocellular carcinoma specifically for smoking.

Abstract
Prior research has demonstrated that specific isoflavones derived from soy may exhibit antitumor effects against many cancers, including oral cancer. Most of this prior research involved isolation and testing of individual soy components, such as genistein, daidzein, and glycitein, which exhibit cytotoxicity against cancerous cells but may also have residual cytotoxic effects on normal cells. Few studies have evaluated whole soy extract, containing a combination of these isoflavones, and other bioreactive compounds, which may function synergistically and more effectively against oral cancers. This study compared the antiproliferative effects of whole soy protein extract (SPE) on CAL 27 and SCC25 oral cancer cell lines in vitro. Administration of SPE significantly inhibited oral cancer growth and exerted these effects at lower concentrations compared with another class of flavonoids (proanthocyanidins) that were previously tested on these cell lines. This SPE-induced growth inhibition correlated with down-regulated mRNA expression in the oral cancer cell-cycle promoter ornithine decarboxylase (ODC), as well as upregulation of caspase-2 and caspase-8, initiators and effectors of apoptosis. These results suggest that SPE may represent a potential chemopreventive or chemotherapeutic option for oral cancer. Moreover, SPE may be more effective than other flavonoids currently used and may be effective at lower concentrations that approximate physiologic serum levels (0-2 μmol/l). This study may help to explain why diets rich in fruits, vegetables, and soy protein are associated with protection against development and progression of oral cancers, although further study is needed to develop specific public health recommendations for oral cancer treatment and prevention.

Abstract
Lung cancer is the most common cause of cancer-related death worldwide and, like many other cancers, is affected by different genetic, epigenetic, and environmental factors. The WW domain-containing oxidoreductase (WWOX) gene is a tumor-suppressor gene located on chromosome 16q23.3-24.1, and it has been shown that it loses its function due to alterations in genetic and epigenetic mechanisms. The aim of this study is to investigate the relationship between lung cancer and WWOX gene. Tumor tissue samples, corresponding normal tissues, and blood samples obtained from 50 lung cancer patients were involved in the study. We analyzed methylation profile by methylation-specific PCR and mutations and polymorphisms by DNA sequencing. Methylation analysis showed that promoter hypermethylation was present in 38 of 50 (76%) patients. In addition, promoter region of WWOX gene of younger patients was more frequently methylated than older patients. Using DNA sequencing, we found four genetic alterations in WWOX gene. Two of them were germline mutations (Exon 4 and 7), and two of them were polymorphic (Exon 6 and 8). We found a new mutation in exon 7 (Arg-254-->Cys) which has not been described previously. The changes in the short-chain dehydrogenase domain of the protein caused by the genetic alterations may affect the function of the gene. We conclude that hypermethylation of WWOX gene promoter region and mutations in the gene might be related to lung carcinogenesis.

Abstract
Objectives To examine the primary risk factor for oral cancer in the US, smoking and tobacco use, among the specific US states that experienced short-term increases in oral cancer incidence and mortality. Methods Population-based data on oral cancer morbidity and mortality in the US were obtained from the National Cancer Institute's (NCI) Surveillance, Epidemiology, and End Results (SEER) database for analysis of recent trends. Data were also obtained from the Centers for Disease Control and Prevention (CDC) Behavioral Risk Factor Surveillance System (BRFSS) to measure current and former trends of tobacco usage. To comprehensive measures of previous state tobacco use and tobacco-related policies, the Initial Outcomes Index (IOI, 1992-1993) and the Strength of Tobacco Control index (SoTC, 1999-2000) were also used for evaluation and comparison. Results Analysis of the NCI-SEER data confirmed a previous report of geographic increases in oral cancer and demonstrated these were state-specific, were not regional, and were unrelated to previously observed increases among females and minorities. Analysis of the CDC-BRFSS data revealed these states had relatively higher percentages of smokers currently, as well as historically. In addition, analysis of the IOI and SoTC indexes suggest that many factors, including cigarette pricing, taxes and home or workplace bans, may have had significant influence on smoking prevalence in these areas. Trend analysis of these data uncovered a recent and significant reversal in smoking rates that suggest oral cancer incidence and mortality may also begin to decline in the near future. Conclusion Due to the rising costs of health care in the US and the limited resources available for health prevention efforts, it is essential to organize and direct more effective efforts by public health officials and epidemiologists, as well as funding from local, state and federal governments, to reduce and eliminate identified health disparities. This study provides evidence how these efforts may be directed to specific geographic areas, and towards the white males, previously thought to be unaffected by the increases in oral cancer among females and minorities.

Abstract
Throughout history, humankind has won the battle against deadly diseases, including small pox and polio, by defeating them through prevention. Cancer prevention is a global priority, but studying history suggests that the journey towards achieving this goal is difficult and full of detours and roadblocks. Epidemiology and clinical evidence clearly indicate that specific genetic, environmental and behavioural factors are associated with an increased risk for cancer development. What can we learn from the past that is applicable to the reality of successful cancer prevention?

Abstract
Aim of this study is the analysis of the price responsiveness of demand for cigarettes and loose tobacco in Germany over the period 1991--2006. In this period the average consumption of all kinds of cigarettes per capita (German population > or = 15 years) declined from 634 pieces/quarter to 457pieces/quarter (-28%). Consumption of factory-made cigarettes decreased from about 545 pieces/quarter to 330 pieces/quarter in 2006 (-39%). In the same time consumption of self-made cigarettes increased from 89 pieces/quarter to 127 pieces/quarter (+42%). A one Euro Cent increase in price is associated with 28 cigarettes of all kinds consumed less per quarter. Data indicate that the different types of cigarettes are substitutes, e.g. there is evidence for a positive relationship between the price of factory-made cigarettes and the consumption of hand-made cigarettes. Thus, the increase in such consumption is rather driven by a positive cross-price effect of 17.01. Data indicate additionally an overall decrease in the cigarette consumption and a partial switch to cheaper loose tobacco. The availability of low-taxed loose tobacco may undermine the public health benefits of higher cigarette prices. Price differentials between tobacco products should be reduced in order to maximize the public health benefits of high cigarette prices.

Abstract
Background Downward trends have been observed in oral cancer incidence and mortality in the US over the past 30 years; however, these declines are not uniform within this population. Several studies have now demonstrated an increase in the incidence and mortality from oral cancers among certain demographic groups, which may have resulted from increased risks or risk behaviors. This study examines the underlying data that comprise these trends, to identify specific populations that may be at greater risk for morbidity and mortality from oral cancers. Methods Oral cancer incidence and mortality data analyzed for this study were generated using the National Cancer Institute's Surveillance, Epidemiology and End Results (SEER) program. Results While oral cancer incidence and mortality rates have been declining over the past thirty years, these declines have reversed in the past five years among some demographic groups, including black females and white males. Sorting of these data by state revealed that eight states exhibited increasing rates of oral cancer deaths, Nevada, North Carolina, Iowa, Ohio, Maine, Idaho, North Dakota, and Wyoming, in stark contrast to the national downward trend. Furthermore, a detailed analysis of data from these states revealed increasing rates of oral cancer among older white males, also contrary to the overall trends observed at the national level. Conclusion These results signify that, despite the declining long-term trends in oral cancer incidence and mortality nationally, localized geographic areas exist where the incidence and mortality from oral cancers have been increasing. These areas represent sites where public health education and prevention efforts may be focused to target these specific populations in an effort to improve health outcomes and reduce disparities within these populations.

Biochim Biophys Acta Gen Subj 2008; 1780:743-9.

Abstract
Fucoxanthin, a major carotenoid in brown sea algae, has recently been demonstrated by us to inhibit the proliferation of colon cancer cells, and this effect was associated with growth arrest. These results, taken together with previous studies with fucoxanthin, suggest that it may be useful in chemoprevention of other human malignancies. The present study was designed to evaluate the molecular mechanisms of fucoxanthin against hepatic cancer using the human hepatocarcinoma HepG2 cell line (HepG2). Fucoxanthin reduced the viability of HepG2 cells accompanied with the induction of cell cycle arrest during the G0/G1 phase at 25 microM. This concentration of fucoxanthin inhibited the phosphorylation of the retinoblastoma protein (Rb) at Serine 780 (Ser780) position 18 h after treatment. The kinase activity of cyclin D and cdk4 complex, responsible for the phosphorylation of Rb Ser780 site, was down-regulated 18 h after the treatment. Western blotting analysis revealed that the expression of cyclin D-type protein was suppressed by treatment of fucoxanthin. This reduction was partially blocked by concurrent treatment with the proteasome inhibitor MG132, indicating the involvement of the proteasome-mediated degradation. In addition, RT-PCR analysis revealed that fucoxanthin also appeared to repress cyclin D mRNA. Thus, both the protein degradation and transcriptional repression seem to be responsible for suppressed cyclin D level in fucoxanthin-treated HepG2 cells which may be related to the antitumorgenic activity.

Abstract
There are geographic and ethnic differences in the incidence of gastric cancer around the world as well as with its trends for each population over time. The incidence patterns observed among immigrants change according to where they live. All of these factors serve to indicate the close association of gastric cancer with modifiable factors such as diet. This review presents epidemiological evidence on the association between dietary factors and gastric cancer based on previous systematic reviews and subsequent updates. Infection with Helicobacter pylori is a strong and established risk factor of gastric cancer but is not a sufficient cause for its development. Substantial evidence from ecological, case-control, and cohort studies strongly suggests that the risk may be increased with a high intake of various traditional salt-preserved foods and salt per se and decreased with a high intake of fruit and vegetables, particularly fruit. However, it remains unclear which constituents in fruit and vegetables play a significant role in gastric cancer prevention. Among them, vitamin C is a plausible candidate supported by a relatively large body of epidemiological evidence. Consumption of green tea is possibly associated with a decreased risk of gastric cancer, although the protective effects have been, for the most part, identified in Japanese women, most of whom are nonsmokers. In contrast, processed meat and N-nitroso compounds may be positively associated with the risk of gastric cancer. In conclusion, dietary modification by reducing salt and salted food intake, as well as by increasing intake of fruit and vitamin C, represents a practical strategy to prevent gastric cancer.

Abstract
This study analyzed possibilities to access European adolescents for tobacco control activities in out-of-school settings as part of comprehensive tobacco control programs. Data on leisure time behaviors of secondary school students were gathered during three waves from six European Union countries as part of the European Smoking Prevention Framework Approach study. The results revealed that streets, shops, sport clubs, swimming pools and snack bars were the most popular leisure time settings for adolescents across the six countries. In addition, leisure time activities were similar across the six countries. European-wide prevention programmes can reach adolescents in similar out-of-school settings. Furthermore, smokers and nonsmokers differed in the places that they visited. Whereas smokers preferred social places such as bars, house/rave parties, discos, snack bars, streets and shops, nonsmokers preferred sport clubs and libraries. Smokers tended to visit more unsupervised and less structured places where smoking tends to be permitted, whereas nonsmokers tended to visit places with more structured activities and places under adult supervision. Over time, both smoking and nonsmoking adolescents tended to spend more of their leisure time in settings with low adult supervision. As structured activities under the supervision of adults can have a protective effect against the involvement in risky behaviours, participation in these types of activities must be promoted. Additional strategies for settings with less supervision need to be developed as they attract more smoking adolescents and older nonsmoking adolescents.

Abstract
BACKGROUND Alcohol and tobacco are responsible for a significant amount of burden of disease, but some diseases may be a result of the interaction between these two risk factors. METHODS Systematic literature review identified articles on the interaction of alcohol and smoking on a number of outcomes related to both risk behaviours. RESULTS The interaction of smoking and alcohol significantly increases risk for aerodigestive cancers, and may increase risk for traffic injury and fire injury, but there were very few quality studies on injury. The indication that the cardioprotective effect of alcohol on coronary heart disease is only valid for smokers, but this result is inconclusive because of small evidence base. CONCLUSIONS The interaction between smoking and alcohol consumption seems to be responsible for a significant amount of disease. Unfortunately, little is known on the mechanisms and details of this interaction on disease outcomes. Future studies, especially for coronary heart disease and injury outcomes, are warranted.

Abstract
Since the development of multiple primary cancers in an individual is considered an unlikely event, it is suspected that a defect in DNA repair or apoptosis is the underlying cause for some of these patients. Therefore, this study was based on the hypothesis that such patients have increased remaining DNA double-strand breaks (DSBs) and reduced levels of apoptosis after in vitro irradiation. To investigate these mechanisms in cancer patients, 19 with multiple primary cancers were selected out of 25 121 cancer patients. For inclusion in this study, patients had to present with first malignancy at an early age, have a positive family history of cancer and no risk factors. The exclusion criteria were recurrence of cancer or metastasis, haematological tumours and tumours possibly connected to a patient risk factor such as smoking or drinking. Their peripheral blood lymphocytes were tested for proper repair of DNA DSBs and apoptosis after in vitro irradiation. DSBs were measured using constant field gel electrophoresis at 0, 8 and 24 h after irradiation. Apoptotic rates were determined at 24, 48 and 72 h after irradiation using the TUNEL assay. We found that patients' lymphocytes had significantly more initial DNA DSBs compared with controls, but there was no difference in the number of remaining DNA DSBs. Apoptotic rates of lymphocytes were only slightly lower in patients than in controls. These findings show that there are limited differences between patients with multiple cancers and healthy individuals. However, we found a trend towards an inverse correlation between remaining DNA DSBs and apoptotic rates in patients' lymphocytes. This is indicative of DNA DSBs persisting in patients' cells, presumably leading to a higher level of stable chromosomal aberrations that may contribute to tumour formation.

Abstract
AIMS AND BACKGROUND To update trends in smoking prevalence in Italy to 2004, and describe the attitudes towards forthcoming regulation of smoking. METHODS Population-based face-to-face survey conducted in March-April 2004 on a sample of 3050 individuals (1509 men and 1541 women) aged 15 or over, representative of the general adult Italian population in terms of age, sex, geographic area, habitat, education and working status. RESULTS Overall, 26.2% of the Italians aged 15 or over described themselves as current cigarette smokers (30.0% of men, 22.5% of women); 19.1% of men and 11.2% of women smoked 15 or more cigarettes per day. Ex-smokers were 17.9% (24.8% of men, 11.2% of women). The difference in smoking prevalence between men and women was greater in the elderly. More educated men, and those residing in northern Italy were less frequently current smokers. Conversely, women with a low level of education (19%) were less frequently current smokers than those with higher education (24%). More than 85% of Italian adult population were in favour of restrictions of smoking in public places, such as cafes and restaurants, and to ban smoking in workplaces. CONCLUSIONS Self-reported smoking prevalence is decreasing in men but not in females. There is widespread support for smoking restriction in public areas.

Abstract
Trends in mortality from breast cancer over the period 1970-2000 were analysed for 38 European countries and the European Union (EU). Age-standardized mortality rates were computed by the direct method, and joinpoint analysis was used to identify significant changes in rates. A favourable pattern in breast cancer mortality in the 25 countries of the EU (as defined in May 2004) was observed after 1989, leading to a fall in overall rates from 21.3/100,000 in 1990 to 18.9 in 2000. The annual percentage change in the EU was -2.1% between 1995 and 2000. Most northern European countries, including several Scandinavian countries and the UK, but also some central and southern European countries like Germany, Poland, the Czech Republic, Austria, Switzerland, Italy and Spain showed appreciable falls in rates (i.e. between 8 and 19% in the last 5 calendar years). The declines were larger below age 50, approaching 20% in several countries. The falls were smaller in France, Greece, Portugal and most eastern European countries. In the Russian Federation, all-age breast cancer mortality increased from 16.1 to 17.3/100,000 (+7.5% over the last 5 calendar years). These patterns reflect converging trends in breast cancer rates across Europe, which can be related to the more uniform reproductive and lifestyle habits. The fall in breast cancer mortality observed in most European countries over the last decade has to be attributed to earlier detection and improved treatment, although the definite reasons for the different trends in various countries remain at least in part unclear.

Abstract
Cervical cancer is a complex and multifactorial disease. Although there are substantial data supporting the causative role of persistent human papillomavirus (HPV) infection in the development of cervical cancer, the complete course of the disease has never been completely understood. Several risk cofactors have been suggested with controversial results. Portugal has the highest incidence of squamous cell carcinoma (SCC) within western Europe and there are no known studies regarding the role of cofactors in SCC. The aim of our study was to evaluate the role of smoking, sexual behaviour, reproductive and contraceptive history, in the time-to-onset (TTO) of severe cervical lesions (HGSIL/SCC) in the Portuguese population. We verified that age of first sexual intercourse under 18 years (odds ratio (OR) 2.8), pregnancy (OR 2.9), first pregnancy under 21 years (2.6), number of pregnancies (OR 2.3-5.4) and parity (OR 1.9-5.7) are risk factors in the development of cervical neoplasia. Smoke exposure index (SEI) was significantly different (P=0.002) between cases and controls. Our results regarding time-to-onset demonstrate that smoking (P<0.001, log rank test), number of sexual partners (P<0.001, log rank test) and use of oral contraceptives (P<0.001, log rank test) are important determinants in the earlier onset of severe cervical lesions. Using this approach, our findings may help to clarify the role of smoking and other cofactors in the persistence and progression of cervical lesions.

Abstract
Gastric carcinoma remains a common disease worldwide with a dismal prognosis. Therefore, it represents a very important health problem. It occurs with a high incidence in Asia and is one of the leading causes of cancer death in the world. Although the incidence and mortality of gastric carcinoma are decreasing in many countries, gastric cancer still represents the second most frequent malignancies in the world and the fourth in Europe. The 5-year survival rate of gastric carcinoma is low. The etiology and pathogenesis are not yet fully known. The study of gastric cancer is important in clinical medicine as well as in public health. Over the past 15 years, integrated research in molecular pathology has clarified the details of genetic and epigenetic abnormalities of cancer-related genes in the course of the development and progression of gastric cancer. Gastric cancer, as all cancers, is the end result of the interplay of many risk factors as well as protective factors. Although epidemiological evidence indicates that environmental factors play a major role in gastric carcinogenesis, the role of immunological, genetic, and immunogenetic factors are thought to contribute to the pathogenesis of gastric carcinoma. Among the environmental factors, diet and Helicobacter pylori are more amenable to intervention aimed at the prevention of gastric cancer. The aim of the present paper is to review and include the most recent published evidence to demonstrate that only a multidisciplinary approach will lead to the advancement of the pathogenesis and prevention of gastric cancer. On the immunogenetic research it is clear that evidence is accumulating to suggest that a genetic profile favoring the proinflammatory response increases the risk of gastric carcinoma.

Abstract
Because gastric cancer is still the most common cancer, its prevention is one of the most important aspects of Japan's cancer control strategy. Observations among Japanese immigrants in the USA and Brazil based on the geographic differences, the trend in cancer incidence with time, and the change in incidence patterns indicate that gastric cancer is closely associated with dietary factors, such as the intake of salt and salted food. In international and intra-Japanese ecological studies, the average salt excretion level, estimated using randomly selected 24-h urine samples in each population, was closely correlated with gastric cancer mortality. Several case-control and cohort studies, including the author's recent works, have shown that a higher intake of some traditional salt-preserved food and salt per se, which was estimated using a validated food-frequency questionnaire, was associated with a risk of gastric cancer. While salted food intake may increase the risk of Helicobacter pylori infection, it can also act synergistically to promote the development of gastric cancer. Based on substantial evidence about the association between salt and salted food intake and the risk of gastric cancer from ecological, case-control, and cohort studies conducted in Japan and other countries, as well as mechanistic plausibility, dietary modification involving less salt and salted food intake is a practical strategy with which to prevent gastric cancer.

Abstract
A case-control study was conducted to investigate the relationship between diet and the risk of lung cancer among women non-smokers and to compare with women smokers in the same population. Data collected by personal interviews from 435 microscopically confirmed cases and 1710 controls were analysed using unconditional logistic regression. In addition to results for all study subjects, associations between diet and lung cancer risk were compared between two highly contrasting groups: smokers (odds ratio (OR) 7.03) and non-smokers (OR 1.00). A protective effect of frequent (daily or several times per week) black tea drinking appeared among non-smoking women (OR 0.65, 95% confidence interval (CI) 0.43-0.99). Among smoking women, protective effects were observed for frequent intake of milk/dairy products (OR 0.56, 95% CI 0.32-0.96), coffee (OR 0.47, 95% CI 0.25-0.88), and wine consumption (daily or weekly OR 0.60, 95% CI 0.37-0.98; monthly OR 0.60, 95% CI 0.39-0.94). Inverse associations with the risk appeared for physical exercise for smokers only, and for the body mass index both among non-smoking and smoking women. Some items of diet may contribute to variation in risk among women in the Czech Republic; their importance seems to vary in relation to their status in smoking, the dominant factor in the aetiology of lung cancer.

Abstract
PURPOSE Autosomal dominant hereditary diffuse gastric cancer (HDGC) is caused by germ-line E-cadherin (CDH1) gene mutations. Early detection of cancer in carriers is difficult because HDGC escapes endoscopic detection. We hypothesized that the glucose metabolism is enhanced in HDGC and that this can be detected with [18F]fluoro-2-deoxy-d-glucose positron emission tomography (FDG-PET). EXPERIMENTAL DESIGN AND RESULTS An asymptomatic twenty-eight year-old female was seen at our outpatient clinic because of a request for screening on HDGC. Her father and younger sister died of diffuse gastric cancer, at the ages of 52 and 27, respectively. Mutational analysis of the CDH1 gene in this patient demonstrated a novel heterozygous splice-site mutation in exon 8 (1135delACGGTAATinsTTAGA). Upper gastrointestinal endoscopies revealed no macroscopic abnormalities, but one of the 40 random biopsy specimens showed well-differentiated signet-cell carcinoma. A FDG-PET scan demonstrated two spots of FDG accumulation, one located in the proximal part of the stomach and the second in the region of the pylorus. A total gastrectomy was performed and microscopic examination showed focal localization of intramucosal adenocarcinoma of the signet-cell type in the cardiac and antrum area. Most notably, the localization of the FDG accumulation matched the localization of the carcinoma. CONCLUSIONS We present an asymptomatic patient from a HDGC family carrying a novel CDH1 mutation in whom FDG-PET scanning facilitated early detection of HDGC. This calls for further investigation of the role of FDG-PET scan as a screening modality in HDGC.

Abstract
Mortality data, abstracted from the World Health Organization database, are presented in tabular form for 26 cancer sites or groups of sites, plus total cancer mortality, in 36 European countries during the period 1995-1999. Trends in mortality are also given in graphic form for 23 major countries plus the European Union as a whole over the period 1960-1999. In the European Union, total cancer mortality declined by 7% for both sexes over the last 5 years considered. The fall since the late 1980s was 10% in both sexes, corresponding to the avoidance of over 90000 deaths per year, as compared to the rates of the late 1980s. For the first time, over the last few years, some leveling of mortality was reported also in the Russian Federation, the Czech Republic, Poland, Hungary and other Eastern European countries, although cancer rates in those areas remain exceedingly high. The overall favorable pattern of cancer mortality over recent years is largely driven by the decline of tobacco-related cancer mortality in men. However, important components of the trends are also the persistence of substantial falls in gastric cancer, mainly in Russia and Eastern Europe, the recent decline in intestinal cancer in both sexes and of breast cancer in women, together with the long-term falls in uterine (cervical) cancer, leukemias, Hodgkin's disease and other neoplasms amenable to advancements in diagnosis and treatment. Female lung cancer mortality has been declining in the Russian Federation, but is still rising in other areas of the continent. Thus, urgent intervention is needed to bring under control the tobacco-related lung cancer epidemic in European women before it reaches the high level observed in North America.

Abstract
Changes in cigarette price have had an appreciable impact on smoking prevalence in several countries. We analysed the price elasticity of demand for cigarettes (effect of price of cigarettes on tobacco consumption) between 1965 and 2000 in Spain. For total consumption of cigarettes, a 1% increase in price is associated with a 0.19% decrease of consumption (price elasticity of -0.19; P<0.01). The real price of blond cigarettes was significantly and inversely associated with blond cigarette consumption: on average, smoking prevalence decreased 1.25% for a 1% increase in the real price of cigarettes (significant price elasticity of -1.25). For black cigarettes we found a lower but still high and significant elasticity of -0.61. There is an inverse relation between price and consumption of cigarettes in Spain, indicating that interventions at the economic level (such as real increases in prices) may have an important public health impact in tobacco control.

Abstract
A variety of lifestyle factors, including physical activity, artificial sweeteners, alcohol consumption and smoking, have been reported to contribute to the risk of developing urological malignancies. A great number of epidemiological studies suggest that sports and physical activity may have a preventive influence on genitourinary tumours, especially on the incidence of prostate cancer. Smoking appears to be the most relevant lifestyle factor significantly increasing both incidence and mortality from bladder cancer. Furthermore, there is evidence implicating an association between tobacco use and kidney cancer. In contrast, prostate and testicular cancers are unlikely to be linked to tobacco use. As far as alcohol is concerned, most studies indicate that neither amount nor type of alcohol seems to be clearly associated with a risk of developing urological malignancies. However, some more recent cohort studies suggest a moderately increased risk for prostate and bladder cancer for specific types of alcohol. On the other hand, there is evidence that moderate alcohol consumption may even protect women from developing renal cancer. Since the introduction of artificial sweeteners, reports of potential cancer risks have circulated periodically through the mass media. The wide distribution of these agents and the fact that mostly combinations of the different compounds are added to a broad variety of food, drinks, drugs, and hygiene products complicates a systematic analysis of their potential impact on the development of urological malignancies. Nevertheless, so far not a single study has convincingly demonstrated a statistically significant risk of bladder cancer due to the consumption of artificial sweeteners. This survey demonstrates that the individual assessment of lifestyle factors not only may identify groups with an increased risk for urological malignancies but also clearly displays a potential for tumour prevention.

Abstract
Incidence, mortality and survival trends for the most frequent cancers affecting women are presented on a worldwide basis. Data sources are represented by several different cancer databases, as no single world cancer database covers these epidemiological measures. Monitoring cancer incidence, mortality and survival are fundamental indicators which allow estimates and predictions of geographical and temporal changes of these diseases, enabling the design and set-up of adequate cancer control activities and national health programs. The observed differences in cancer incidence, mortality and survival in more developed countries compared with less developed countries (as defined by WHO) are mainly due to different individual and social risk factors between the two geo-political areas. For some cancers, advancements in screening, diagnosis and treatment in the more developed areas were the most effective factors in reducing incidence and mortality as well as prolonging survival. These effects were not detected in the less developed areas because of the limited access to primary and specialist care.

Abstract
Changes in cigarette price have had an appreciable impact on smoking consumption in several countries. We analysed the price elasticity of demand for cigarettes in Italy over the period 1970-2001. A 1% increase in price of cigarettes led to a 0.30% decline in smoking prevalence and to a 0.43% decline in cigarette consumption. The present analyses confirm the existence of an inverse association between price and prevalence/consumption of cigarettes in Italy, and indicate that economic aspects may have important public health implications in tobacco control.
