RESUMEN
OBJECTIVE: Endogenous and exogenous hormonal factors have been associated with female breast, genital, and colorectal cancer risk. The aim of the present study is to conduct an evidence-based evaluation of the fraction of cancers attributable to and prevented by exogenous hormonal (i.e., combined oral contraceptives [COC] and combined estrogen-progestogen menopausal therapy [CEPMT]) and reproductive factors (i.e., parity and breastfeeding) in Italy. STUDY DESIGN: We calculated the population attributable and prevented fractions combining relative risks and prevalence of exposure in Italian women. Italian cancer incidence and mortality data were extracted from national sources and used to estimate the number of cancer cases and deaths attributable to reproductive factors and exogenous hormones in Italy in 2020. For long-term effects, a 20-year latency period was considered. RESULTS: COC were responsible for 4.4 % of breast and 10.9 % of cervical cancers in women aged 15-44, but also avoided 6.4 % of endometrial, 5.6 % of ovarian, and 2.9 % of colorectal cancers in women of all ages. Overall, COC use prevented 1174 cancer diagnoses and 577 cancer deaths. CEPMT caused 0.4 % of breast cancers at age 45-69. Low parity accounted for 8.1 %, 11.8 % and 15.5 % of breast, endometrial and ovarian cancers, respectively (6267 cases, 1796 deaths). Breastfeeding avoided 6.4 % of breast cancers (3775 cases, 897 deaths). CONCLUSIONS: Our analysis quantified the complex effects of hormonal and reproductive factors on cancer burden in Italian women.
RESUMEN
BACKGROUND: Pancreatic cancer risk has been associated with increased serum cholesterol level, which is in turn partially influenced by diet. This study aimed at evaluating the association between pancreatic cancer risk and the adherence to a plant-based cholesterol-lowering diet. METHODS: Data were derived from an Italian case-control study including 258 pancreatic cancer patients and 551 controls. The cholesterol-lowering diet score was based on seven components: high intakes of (i) non-cellulosic polysaccharides (a proxy of viscous fibers), (ii) monounsaturated fatty acids, (iii) legumes, and (iv) seeds/corn oils (a proxy of phytosterols); and low intakes of (v) saturated fatty acids, (vi) dietary cholesterol, and (vii) food with a high glycemic index. The score was calculated adding one point for each fulfilled component, thus ranging from zero (no adherence) to seven (complete adherence). The odds ratios (ORs) and 95% confidence intervals (CIs) were estimated through the logistic regression model. RESULTS: Scores 5-7 were associated with reduced cancer risk (OR = 0.30; 95% CI: 0.18-0.52) compared to scores 0-2. CONCLUSIONS: Adherence to a plant-based cholesterol-lowering diet was associated with a reduced risk of pancreatic cancer.

BACKGROUND: Aspirin and statins have been suggested to have potential chemopreventive effects against gastric cancer (GC), although the results of previous studies have been inconsistent. This study therefore aimed to investigate the association between the use of aspirin and statins and GC. METHODS: A pooled analysis of seven case-control studies within the Stomach Cancer Pooling Project, including 3220 cases and 9752 controls, was conducted. Two-stage modeling analyses were used to estimate the association between aspirin and statin use and GC after adjusting for potential confounders. RESULTS: The pooled odds ratio (OR) of GC for aspirin users versus nonusers was 0.72 (95% confidence interval [CI], 0.54-0.95). The protective effect of aspirin appeared stronger in individuals without a GC family history (OR, 0.60; 95% CI, 0.37-0.95), albeit with borderline heterogeneity between those with and without a family history (p = .064). The OR of GC decreased with increasing duration of aspirin use, with an OR of 0.41 (95% CI, 0.18-0.95) for durations of ≥15 years. An inverse, nonsignificant association with the risk of GC was observed for the use of statins alone (OR, 0.79; 95% CI, 0.52-1.18). CONCLUSIONS: These findings suggest that aspirin use, particularly long-term use, is associated with a reduced risk of GC, whereas a similar association was not observed with statins, possibly because of the low frequency of use.
RESUMEN
BACKGROUND: Tobacco smoking is still frequent in Italy and a major cause of cancer globally. We estimated the burden of smoking-related cancer in Italy. METHODS: To calculate the population attributable fraction (PAF), we adopted a counterfactual scenario for which all individuals never smoked. The PAF of current and former smoking and second-hand smoke (SHS) was estimated for cancers associated with these habits according to the International Agency for Research on Cancer. Relative risk estimates and prevalence of exposure were derived from large-scale studies and national surveys, respectively. A 20-year latency period between exposure and cancer was considered. Cancer incidence data for 2020 and mortality data for 2017 were obtained from the Italian Association of Cancer Registries. RESULTS: Tobacco smoking caused, in men and women respectively, 90.0â¯% and 58.3â¯% of lung; 67.8â¯% and 53.5â¯% of pharyngeal; 47.0â¯% and 32.2â¯% of bladder; 45.9â¯% and 31.7â¯% of oral; 36.6â¯% and 23.6â¯% of esophageal; 23.0â¯% and 14.0â¯% of pancreatic cancer and lower percentages of cancers at other sites. Tobacco smoking accounted for 23.9â¯% and 7.7â¯% of new cancer cases in 2020, and 32.1â¯% and 11.3â¯% of cancer deaths in 2017 in men and women, respectively, corresponding to 17.3â¯% of cases and 24.5â¯% of cancer deaths overall. The PAF of lung cancer due to SHS in never smoking women married with smokers was 13.0â¯%. CONCLUSIONS: Tobacco smoking is a primary cause of cancer in Italy in both sexes. Tobacco control policies are warranted.
RESUMEN
OBJECTIVE: To provide a comprehensive picture of trends in parents' age and total fertility rate in selected most populous high-income countries from Europe and North America. STUDY DESIGN: Data were retrieved from official statistics published by the United Nations, the World Bank, the European Union (EU), and by national health statistics offices. RESULTS: Mean maternal age at birth showed increasing trends in all considered countries; in 2020, the highest mean age was observed in Italy (32.2) and Spain (32.3), and the lowest one in the USA (28.8). Mean maternal age at first birth also showed upward trends. In the 1990s, mean age at first birth ranged from 25.5 to 26.9 years, except for the USA where it was below 25 years. The countries with the highest average maternal age at first birth were Italy and Spain, reaching 31 years over the most recent years. Data on mean paternal age at birth were scant. In Germany (2019) it was 34.6 and in the USA (2014) 27.9 years. In Italy, mean paternal age increased from 34.2 in 2000 to 35.5 in 2018, in the UK from 30.7 in 1990 to 33.4 in 2017, and in Canada, a decrease was observed from 29.1 in 2006 to 28.3 in 2011. Finally, Sweden and the USA had the highest fertility rates, around two children in some years, while Italy and Spain had the lowest ones, with less than 1.5 children over the whole period. CONCLUSIONS: Monitoring of trends in reproductive factors is crucial to gain insight into society from a cultural and sociological point of view and to analyze the impact of these changes on reproductive health and related conditions.

Prebiotics may influence the risk of hormone-related female cancers by modulating the gut microbiota involved in estrogens metabolism. We evaluated the association of fiber-type prebiotic intake with breast, endometrial, and ovarian cancers. Data derived from a network of Italian hospital-based case-control studies (1991-2006), including 2560 cases of cancer of the breast (2588 controls), 454 of the endometrium (908 controls) and 1031 of the ovary (2411 controls). Inulin-type fructans (ITFs), and selected fructo-oligosaccharides (FOSs, nystose, kestose and 1F-ß-fructofuranosylnystose) and galacto-oligosaccharides (GOSs, raffinose and stachyose) were quantified in food products. Prebiotic intake was estimated by multiplying food frequency questionnaire intake by the foods' prebiotic content. Odds ratios (OR) and the corresponding 95% confidence intervals (CI) were derived by multiple logistic regression models. Nystose intake was marginally directly associated with breast (OR for the 4th versus the 1st quartile 1.20, 95% CI: 1.00-1.45), ovarian (OR 1.39, 95% CI: 1.04-1.84) and endometrial cancer risk (OR 1.32, 95% CI: 0.85-2.03). High 1F-ß-fructofuranosylnystose intake was inversely associated with ovarian cancer (OR 0.67, 95% CI: 0.52-0.85). ITFs, kestose, raffinose and stachyose were not associated with the three cancers. The intake of most fiber-type prebiotics was not appreciably and consistently associated with breast, endometrial and ovarian cancer risks.
RESUMEN
Dietary folate intake has been identified as a potentially modifiable factor of gastric cancer (GC) risk, although the evidence is still inconsistent. We evaluate the association between dietary folate intake and the risk of GC as well as the potential modification effect of alcohol consumption. We pooled data for 2829 histologically confirmed GC cases and 8141 controls from 11 case-control studies from the international Stomach Cancer Pooling Consortium. Dietary folate intake was estimated using food frequency questionnaires. We used linear mixed models with random intercepts for each study to calculate adjusted odds ratios (OR) and 95% confidence interval (CI). Higher folate intake was associated with a lower risk of GC, although this association was not observed among participants who consumed >2.0 alcoholic drinks/day. The OR for the highest quartile of folate intake, compared with the lowest quartile, was 0.78 (95% CI, 0.67-0.90, P-trend = 0.0002). The OR per each quartile increment was 0.92 (95% CI, 0.87-0.96) and, per every 100 µg/day of folate intake, was 0.89 (95% CI, 0.84-0.95). There was a significant interaction between folate intake and alcohol consumption (P-interaction = 0.02). The lower risk of GC associated with higher folate intake was not observed in participants who consumed >2.0 drinks per day, ORQ4v Q1 = 1.15 (95% CI, 0.85-1.56), and the OR100 µg/day = 1.02 (95% CI, 0.92-1.15). Our study supports a beneficial effect of folate intake on GC risk, although the consumption of >2.0 alcoholic drinks/day counteracts this beneficial effect.

PURPOSE: Gastric cancer (GC) is among the leading causes of cancer mortality worldwide. The objective of this study was to investigate the association between dietary fiber intake and GC. METHODS: We pooled data from 11 population or hospital-based case-control studies included in the Stomach Cancer Pooling (StoP) Project, for a total of 4865 histologically confirmed cases and 10,626 controls. Intake of dietary fibers and other dietary factors was collected using food frequency questionnaires. We calculated the odds ratios (OR) and 95% confidence intervals (CI) of the association between dietary fiber intake and GC by using a multivariable logistic regression model adjusted for study site, sex, age, caloric intake, smoking, fruit and vegetable intake, and socioeconomic status. We conducted stratified analyses by these factors, as well as GC anatomical site and histological type. RESULTS: The OR of GC for an increase of one quartile of fiber intake was 0.91 (95% CI: 0.85, 0.97), that for the highest compared to the lowest quartile of dietary fiber intake was 0.72 (95% CI: 0.59, 0.88). Results were similar irrespective of anatomical site and histological type. CONCLUSION: Our analysis supports the hypothesis that dietary fiber intake may exert a protective effect on GC.

BACKGROUND: Evidence on the potential association between dietary copper intake and gastric cancer (GC) is lacking. Thus, we aimed to evaluate this association within the Stomach cancer Pooling (StoP) Project-an international consortium of epidemiological studies on GC. METHODS: Data from five case-control studies within the StoP Project were included (2448 cases, 4350 controls). We estimated adjusted odds ratios (ORs) and 95% CIs for the association between dietary copper intake and GC using multivariable mixed-effects logistic regression models. We also modelled the dose-response relationship between copper intake and GC using a logistic mixed-effects model with fractional polynomial. RESULTS: The OR for the highest quartile of copper intake compared with the lowest one was 0.78 (95% CI: 0.63-0.95; P for trend = 0.013). Results were similar for non-cardia-type (OR: 0.72; 95% CI: 0.57-0.91), intestinal-type (OR: 0.75; 95% CI: 0.56-0.99) and other histological-type GC (OR: 0.65; 95% CI: 0.44-0.96). The dose-response analysis showed a steep decrease in ORs for modest intakes (<1 mg/day), which were subsequently steady for ≤3 mg/day (OR: 0.09; 95% CI: 0.02-0.41) and slowly increased for higher intakes. CONCLUSIONS: The findings of our large study suggest that copper intake might be inversely associated with GC, although their confirmation by prospective studies is required.

INTRODUCTION: We estimated cancer mortality figures in five major Asian countries and Australia for 2024, focusing on stomach cancer, a leading cause of cancer-related deaths in Eastern Asia. METHODS: We computed country- and sex-specific annual age-standardized rates (ASRs) for total cancers and the 10 most common cancer sites, using WHO and the United Nations Population Division databases from 1970 to 2021 or the latest available year. We predicted figures for 2024 and estimated the number of avoided cancer deaths in 1994-2024. RESULTS: All cancers combined ASR declined between 2015-2019 and 2024 across considered countries and sexes. In 2024, the lowest predicted male rate is in the Philippines (75.0/100â 000) and the highest in Australia (94.2/100â 000). The Republic of Korea is predicted to have the lowest female ASR (42.1/100â 000) while the Philippines the highest (74.5/100â 000). Over the last three decades, 121â 300 deaths were estimated to be avoided in Hong Kong SAR, 69â 500 in Israel, 1â 246â 300 in Japan, 653â 300 in the Republic of Korea, 303â 300 in Australia, and 89â 700 among Philippine men. Mortality from stomach cancer has been decreasing since 1970 in all considered countries and both sexes. Significant decreases are at all age groups Male rates remain, however, high in Japan (8.7/100â 000) and the Republic of Korea (6.2/100â 000). CONCLUSION: Declining cancer mortality is predicted in the considered countries, notably reducing stomach cancer burden. Stomach cancer, however, remains a major public health issue in East Asia.
RESUMEN
BACKGROUND: Previous studies suggest that dietary vitamin C is inversely associated with gastric cancer (GC), but most of them did not consider intake of fruit and vegetables. Thus, we aimed to evaluate this association within the Stomach cancer Pooling (StoP) Project, a consortium of epidemiological studies on GC. METHODS: Fourteen case-control studies were included in the analysis (5362 cases, 11,497 controls). We estimated odds ratios (ORs) and corresponding 95% confidence intervals (CIs) for the association between dietary intake of vitamin C and GC, adjusted for relevant confounders and for intake of fruit and vegetables. The dose-response relationship was evaluated using mixed-effects logistic models with second-order fractional polynomials. RESULTS: Individuals in the highest quartile of dietary vitamin C intake had reduced odds of GC compared with those in the lowest quartile (OR: 0.64; 95% CI: 0.58, 0.72). Additional adjustment for fruit and vegetables intake led to an OR of 0.85 (95% CI: 0.73, 0.98). A significant inverse association was observed for noncardia GC, as well as for both intestinal and diffuse types of the disease. The results of the dose-response analysis showed decreasing ORs of GC up to 150-200 mg/day of vitamin C (OR: 0.54; 95% CI: 0.41, 0.71), whereas ORs for higher intakes were close to 1.0. CONCLUSIONS: The findings of our pooled study suggest that vitamin C is inversely associated with GC, with a potentially beneficial effect also for intakes above the currently recommended daily intake (90 mg for men and 75 mg for women).

BACKGROUND: Diabetes has been associated with colorectal cancer. We evaluated whether adherence to a diabetes risk reduction diet (DRRD) can favorably influence the risk of colorectal cancer. METHODS: Data came from a multicentric Italian case-control study including 1,953 histologically confirmed colorectal cancer cases and 4,154 hospital controls admitted for acute nonneoplastic diseases. Diet was assessed through a validated and reproducible food frequency questionnaire. The DRRD score was computed assigning higher values for higher consumption of cereal fiber, fruit, coffee, nuts and a higher polyunsaturated/saturated fats ratio and for lower glycemic index and lower consumption of red/processed meat and sweetened beverages and fruit juices. The ORs and the corresponding 95% confidence intervals (CI) of colorectal cancer according to the DRRD score were obtained using logistic regression models adjusting for total energy intake and other major confounders. RESULTS: The DRRD was inversely related to colorectal cancer risk. The ORs of colorectal cancer were 0.77 (95% CI, 0.67-0.89) for the third versus first score tertile (Ptrend < 0.001) and 0.92 (95% CI, 0.87-0.96) for a 3-point increment in the score. Inverse associations were observed for colon and rectal cancers and were consistent in strata of sex, age, and other major covariates. CONCLUSIONS: A higher adherence to a DRRD was inversely associated with colorectal cancer risk. IMPACT: Given the high incidence and mortality rates of colorectal cancer, adherence to a DRRD can have relevant prevention and public health implications.

BACKGROUND: The incidence rates of endometrial cancer are increasing, which may partly be explained by the rising prevalence of obesity, an established risk factor for endometrial cancer. Hypertension, another component of metabolic syndrome, is also increasing in prevalence, and emerging evidence suggests that it may be associated with the development of certain cancers. The role of hypertension independent of other components of metabolic syndrome in the etiology of endometrial cancer remains unclear. In this study, we evaluated hypertension as an independent risk factor for endometrial cancer and whether this association is modified by other established risk factors. METHODS: We included 15,631 endometrial cancer cases and 42,239 controls matched on age, race, and study-specific factors from 29 studies in the Epidemiology of Endometrial Cancer Consortium. We used multivariable unconditional logistic regression models to estimate ORs and 95% confidence intervals (CI) to evaluate the association between hypertension and endometrial cancer and whether this association differed by study design, race/ethnicity, body mass index, diabetes status, smoking status, or reproductive factors. RESULTS: Hypertension was associated with an increased risk of endometrial cancer (OR, 1.14; 95% CI, 1.09-1.19). There was significant heterogeneity by study design (Phet < 0.01), with a stronger magnitude of association observed among case-control versus cohort studies. Stronger associations were also noted for pre-/perimenopausal women and never users of postmenopausal hormone therapy. CONCLUSIONS: Hypertension is associated with endometrial cancer risk independently from known risk factors. Future research should focus on biologic mechanisms underlying this association. IMPACT: This study provides evidence that hypertension may be an independent risk factor for endometrial cancer.

We updated to December 2023 the main findings of the stomach cancer pooling (StoP) project including about 13 000 cases and 31 000 controls from 29 case-control and 5 nested studies. The StoP project quantified more precisely than previously available the positive associations of tobacco smoking, high alcohol consumption, meat intake, selected occupations (e.g. agricultural and miners), gastric ulcer and family history with gastric cancer and the inverse associations with socioeconomic status and selected aspects of diet (fruits, including citrus fruits, vegetables, including allium and mushrooms, and polyphenols). No consistent associations were found with coffee, yoghurt and leisure-time physical activity, metformin or proton pump inhibitors use.

Evidence on the relationship between legume consumption and risk of specific cancer sites is inconclusive. We used data from a series of case-controls studies, conducted in Italy and in the Swiss Canton of Vaud between 1991 and 2009 to quantify the association between legume consumption and several cancer sites including oral cavity, esophagus, larynx, stomach, colorectum, breast, endometrium, ovary, prostate and kidney. Multiple logistic regression models controlled for sex, age, education, smoking, alcohol, body mass index, physical activity, comorbidities, and consumption of fruit, vegetables, processed meat and total calorie intake were used to estimate the odds ratios (OR) for different cancer sites and their corresponding 95% confidence intervals(CI). For female hormone-related cancers, the models also included adjustments for age at menarche, menopausal status and parity. Although most of the estimates were below unity, suggesting a protective effect, only colorectal cancer showed a significant association. Compared to no consumption, the OR for consuming at least one portion of legumes was 0.79 (95% CI: 0.68-0.91), the OR for consuming two or more portions was 0.68 (95% CI: 0.57-0.82) and the estimate for an increment of one portion per week was 0.87 (95% CI: 0.81-0.93). The inverse association between legume consumption and colorectal cancer suggests a possible role of legumes in preventing cancer risk.

Mortality from cutaneous malignant melanoma (CMM) increased in the past, but trends have been favorable in more recent years in many high-income countries. However, incidence has been increasing in several countries. We provided an up-to-date overview of mortality trends from CMM. We analyzed death certification data from the WHO in selected countries worldwide from 1980 to the most recent available calendar years. We also reported incidence data derived from Cancer Incidence in Five Continents from 1990 to 2012. Separate analyses were performed for young adults aged 20-44 and middle-aged adults aged 45-64 years. Mortality from CMM in all age groups showed a favorable pattern in the majority of the countries considered. Mortality trends declined by 40 to 50% in Australia over the last decades, confirming the importance of prevention measures. Considering young adults aged 20-44, Australia, New Zealand and Northern Europe reported the highest death rates for both sexes (>0.90/100â 000 in men and >0.60/100â 000 in women) while Japan, the Philippines, and Latin America the lowest ones (<0.50/100â 000 and <0.35/100â 000 in men and women, respectively). Incidence trends were stable or upward in most countries, with higher rates among women. Our study highlights a global reduction of CMM mortality over the last three decades. The increasing awareness of risk factors, mainly related to UV exposure, along with early diagnosis and progress in treatment for advanced disease played pivotal roles in reducing CMM mortality, particularly in Australia.

INTRODUCTION: Comparing cancer mortality and associated risk factors among immigrant populations in a host country to those in their country of origin reveals disparities in cancer risk, access to care, diagnosis, and disease management. This study compares cancer mortality between the German resident population and Germany-born individuals who migrated to the US. METHODS: Cancer mortality data from 2008-2018 were derived for Germans from the World Health Organization database and for Germany-born Americans resident in four states (California, Florida, Massachusetts, and New York) from respective Departments of Vital Statistics. We calculated age-standardized mortality rates (ASMRs) using the European standard population and standardized mortality ratios (SMR) compared to the German resident population along with 95% confidence intervals (CIs). RESULTS: Germany-born American males had lower ASMRs (253.8 per 100,000) than German resident population (325.6 per 100,000). The difference in females was modest, with ASMRs of 200.7 and 203.7 per 100,000, respectively. For all cancers, Germany-born American males had an SMR of 0.72 (95% CI: 0.70-0.74) and females 0.98 (95% CI: 0.95-1.00). Male SMRs among Germany-born Americans were significantly below one for oral cavity, stomach, colorectal, liver, lung, prostate, and kidney cancer. Among females, SMRs were below one for oral cavity, stomach, colorectal, gallbladder, breast, cervix uteri, and kidney cancer. For both sexes, SMRs were over one for bladder cancer (1.14 for males, 1.21 for females). Mortality was higher for lung cancer (SMR: 1.68), non-Hodgkin's lymphoma (1.18) and uterine cancer (1.22) among Germany-born American females compared to the German resident population. CONCLUSION: Germany-born American males but not females showed lower cancer mortality than German resident population. Disparities may stem from variations in risk factors (e.g., smoking and alcohol use) as well as differences in screening practices and participation, cancer treatment, besides some residual potential "healthy immigrant effect".

OBJECTIVE: Anal cancer is a rare disease, affecting more frequently women than men, mainly related to human papillomavirus infection (HPV). Rising incidence and mortality have been reported over the past four decades in different countries. METHODS: To provide an up-to-date overview of recent trends in mortality from anal cancer, we analysed death certification data provided by the WHO in selected countries worldwide over the period from 1994 to 2020. We also analysed incidence derived from Cancer Incidence in Five Continents from 1990 to 2012 for all histologies as well as for anal squamous cell carcinoma (SCC). RESULTS: The highest age-standardised mortality rates around 2020 were registered in Central and Eastern Europe, such as Slovakia (0.9/100â 000 men and 0.40/100â 000 women), in the UK (0.24/100â 000 men and 0.35/100â 000 women), and Denmark (0.33/100â 000 for both sexes), while the lowest ones were in the Philippines, Mexico, and Japan, with rates below 0.10/100â 000 in both sexes. Upwards trends in mortality were reported in most countries for both sexes. Similarly, incidence patterns were upward or stable in most countries considered for both sexes. In 2008-2012, Germany showed the highest incidence rates (1.65/100â 000 men and 2.16/100â 000 women). CONCLUSION: Attention towards vaccination against HPV, increased awareness of risk factors, mainly related to sexual behaviours and advancements in early diagnosis and management are required to control anal cancer incidence and mortality.

BACKGROUND: Non-communicable diseases have been rapidly increasing in African countries. We provided updated cancer death patterns in selected African countries over the last two decades. METHODS: We extracted official death certifications and population data from the WHO and the United Nations Population Division databases. We computed country- and sex-specific age-standardized mortality rates per 100â 000 person-years for all cancers combined and ten major cancer sites for the periods 2005-2007 and 2015-2017. RESULTS: Lung cancer ranked first for male cancer mortality in all selected countries in the last available period (with the highest rates in Réunion 24/100â 000), except for South Africa where prostate cancer was the leading cause of death (23/100â 000). Prostate cancer ranked second in Morocco and Tunisia and third in Mauritius and Réunion. Among Egyptian men, leukemia ranked second (with a stable rate of 4.2/100â 000) and bladder cancer third (3.5/100â 000). Among women, the leading cancer-related cause of death was breast cancer in all selected countries (with the highest rates in Mauritius 19.6/100â 000 in 2015-2017), except for South Africa where uterus cancer ranked first (17/100â 000). In the second rank there were colorectal cancer in Tunisia (2/100â 000), Réunion (9/100â 000) and Mauritius (8/100â 000), and leukemia in Egypt (3.2/100â 000). Colorectal and pancreas cancer mortality rates increased, while stomach cancer mortality rates declined. CONCLUSION: Certified cancer mortality rates are low on a global scale. However, mortality rates from selected screening detectable cancers, as well as from infection-related cancers, are comparatively high, calling for improvements in prevention strategies.
