We estimated cancer mortality statistics for the current year in seven major Latin American countries, with a focus on colorectal cancer. We retrieved official death certification data and population figures from the World Health Organization and the Pan American Health Organization databases. We analysed mortality from all neoplasms combined and for selected cancer sites. We estimated numbers of deaths and age-standardized mortality rates for the year 2021 using a logarithmic Poisson count data joinpoint model. Total cancer mortality is predicted to decline in all countries considered for both sexes, with the exception of Argentinian women. The lowest total mortality rates were predicted in Mexico (65.4/100 000 men and 62.3 in women), the highest ones were in Cuba (133.3/100 000 men and 91.0 in women). Stomach cancer rates have been decreasing since 1970 in all countries; colorectal cancer started to decline over recent calendar periods. Rates for this cancer were unfavourable in the youngest age group. Lung cancer trends declined in males and remained comparatively low in all countries except Cuba. In Cuba, lung cancer rates in women overtook those for breast. Mortality from cancers of the breast, (cervix) uterus, ovary, prostate and bladder, as well as leukemia mostly showed favourable trends. A marked variability in rates across Latin American countries persists, and rates were relatively high for stomach, uterus, prostate and lung cancers, as compared to Europe and North America, suggesting the need to improve preventive strategies. Colorectal cancer mortality was relatively low in Latin America, except in Argentina, and short-term predictions remain moderately favourable.


 Background: Coffee consumption in relation to female hormone-related cancers has been investigated but metaanalyses regarding breast and ovarian cancer include studies published up to 2012 with inconsistent results for ovarian cancer.
 Methods: We conducted two updated meta-analyses of studies published up to June 2016 to quantify the association of coffee intake with breast and ovarian cancer risk with random effects models. We used the dataset developed by the International Agency for Research on Cancer Working Group for Monograph 116 meeting (May 2016). We additionally performed a PubMed search in June 2016.
 Results: Summary relative risks (RRs) (95% confidence intervals (CI)) for the study-specific highest vs. lowest coffee consumption were for breast and ovarian cancer respectively: 0.97 (0.93–1.00, Ι2 5.5%, 40 studies, 76,728 cases) and 1.03 (0.93–1.14, Ι 2 31.9%, 31 studies, 13,111 cases). For decaffeinated coffee the corresponding RRs were: 1.00 (0.93-1.08, I2 32.2%, 13 studies) and 0.83 (0.71-0.96, I2 about 0%, 9 studies). The association of coffee with ovarian cancer risk was higher among publications before (RR=1.37, 1.12–1.69) compared to after 2000 (RR=0.96, 0.86-1.06).
 Conclusion: Our meta-analyses provide strong, quantitative evidence that coffee consumption is not related to breast cancer risk and appears to be unrelated to ovarian cancer risk.

In this paper we present the R implementation of a GLIM macro which fits age-period-cohort model following Osmond and Gardner. In addition to the estimates of the corresponding model, owing to the programming capability of R as an object oriented language, methods for printing, plotting and summarizing the results are provided. Furthermore, the researcher has fully access to the output of the main function (apc) which returns all the models fitted within the function. It is so possible to critically evaluate the goodness of fit of the resulting model

Substantial progress has been made in the diagnosis, management, and treatment of breast cancer over the last decades. This has affected mortality rates but has also led to inequality in epidemiological trends between different regions of the world. We extracted death certification data for breast cancer from the World Health Organization database. We analyzed trends in breast cancer mortality in selected countries from America, Asia, and Oceania over the 1980-2017 period and predicted numbers of deaths and rates for 2025. In North America, we observed decreased breast cancer mortality, reaching a rate of about 13/100,000 women in 2017. In Latin American countries, breast cancer mortality rates did not consistently decrease. The highest decreases in mortality were observed in Australia. Mortality trends in Asian countries remained among the lowest globally. We have predicted decreased mortality from breast cancer in 2025 for most of the analyzed countries. The epidemiological situation regarding breast cancer mortality is expected to change in the coming years. Advancements in diagnosis and treatment of breast cancer must be extended in various areas of the world to obtain global control of breast cancer mortality.

Abstract Aims To develop and to validate a Cancer Multimorbidity Score (CMS) predictive of mortality in elderly patients affected by solid tumor, by using population‐based administrative Italian databases. Methods Through administrative databases of Lombardy Region (Northern Italy), a cohort of patients aged ≥65 years with a new diagnosis of solid tumor during the period 2009–2014 was identified. Sixty‐one conditions and diseases, measured from hospital inpatient diagnosis and outpatient drug prescription within 2 years before cancer diagnosis in a training set randomly including 70% of the cohort patients were tested to predict 5‐year mortality using a Cox regression model. Regression coefficients were used for assigning a weight to the predictive conditions, selected by the LASSO method. Weights were summed up in order to produce an aggregate score (the CMS). CMS performance was evaluated on a validation set, including the remaining 30% of the cohort patients, in terms of discrimination and calibration. Results The study cohort included 148,242 cancer patients. Thirty conditions were selected as independent predictors of 5‐year mortality and were included in the computation of the CMS. The area under the receiving operating characteristics curve was 0.68, becoming 0.71 when considering 1‐year mortality as outcome and reaching values of 0.74 and 0.81 when focusing on patients with breast and prostate cancer, respectively. A strong increasing trend in mortality was observed with increasing CMS value. Conclusions CMS represents a new useful tool for identifying high‐risk elderly cancer patients in everyday clinical practice, as well as for risk adjustment in clinical and epidemiological studies.

Abstract Introduction: Phospholipids are possible favorable agents for colorectal cancer (CRC). Choline has been inversely related to CRC risk but findings are inconsistent. Our study aimed to assess the effect of dietary sphingomyelin (SM) choline moiety and total choline on risk of CRC. Method: This analysis is based on a multicenter case–control study conducted between 1992 and 1996 in Italy. A total of 6107 subjects were enrolled, including 1225 colon cancer cases, 728 rectal cancer cases and 4154 hospital-based controls. We applied data on the composition of foods in terms of SM choline moiety and choline intake on dietary information collected through a validated food-frequency questionnaire. Odds ratio (OR) for energy-adjusted tertiles of SM choline moiety and choline were estimated through logistic regression models adjusted for sex, age, center, education, alcohol consumption, body mass index, family history of CRC, and physical activity. Results: Choline was inversely related to CRC risk (OR=0.85, 95% confidence interval [CI] 0.73-0.99). This association was consistent in colon and rectal cancer. SM choline moiety was not associated with CRC risk (OR=0.96, 95% CI 0.84-1.11). Conclusion: This study shows an inverse association between choline intake and CRC, while no association was found with SM choline moiety.

Flavonoids have been inversely associated to colorectal cancer (CRC) and are plausible intermediaries for the relation among gut microbiome, intestinal permeability and CRC. We analyzed the relation of flavonoid intake with CRC and blood bacterial DNA. We conducted a case–control study in Italy involving 100 incident CRC cases and 200 controls. A valid and reproducible food–frequency questionnaire was used to assess dietary habits and to estimate six flavonoid subclass intakes. We applied qPCR and 16S rRNA gene profiling to assess blood bacterial DNA. We used multiple logistic regression to derive odds ratios (ORs) of CRC and Mann–Whitney and chi-–square tests to evaluate abundance and prevalence of operational taxonomic units (OTUs) according to flavonoid intakes. Inverse associations with CRC were found for anthocyanidins (OR for the highest versus the lowest tertile = 0.24, 95% confidence interval, CI = 0.11–0.52) and flavanones (OR = 0.18, 95% CI = 0.08–0.42). We found different abundance and prevalence according to anthocyanidin and flavanone intake for OTUs referring to Oligoflexales order, Diplorickettsiaceae family, Staphylococcus, Brevundimonas, Pelomonas and Escherischia–Shigella genera, and Flavobacterium and Legionella species. The study provides evidence to a protective effect of dietary anthocyanidins and flavanones on CRC and suggests an influence of flavonoids on blood bacterial DNA, possibly through intestinal permeability changes.

In the pooled analysis of 11 case-control studies in a large consortium (i.e., the Stomach cancer Pooling (StoP) consortium), we found a positive association between GU and risk of GC and no association between DU and GC risk.

Colorectal cancer risk was inversely associated with the intake of dietary GOSs, but not ITFs and FOSs.

Canned fish is a widely consumed and affordable food whose effect on cancer risk has been little investigated. We studied its effect on risk of upper digestive tract cancers using data from a network of hospital-based case-control studies from Northern Italy providing information about canned fish consumption as a separate item and including a total of 946 patients with oral cavity and pharynx cancer, 304 patients with esophageal cancer, 230 patients with gastric cancer and 3273 controls. Twenty-three percent of patients with cancer of the oral cavity or pharynx and 26% of those with cancer of the stomach consumed ≥1 serving per week of canned fish, compared to 40% and 49% of the respective control group. Among cases of esophageal cancer and controls 22% consumed ≥1 serving per week of canned fish. Odds ratios for ≥1 vs <1 portion per week were 0.79 (95% Confidence Interval, CI: 0.64-0.97) for cancer of the oral cavity and pharynx, and 0.59 (95% CI: 0.41-0.86) for stomach cancer, whereas there was no inverse association with esophageal cancer. These findings suggest a favorable role of canned fish for selected upper digestive tract cancers.

The identification of advanced fibrosis by applying noninvasive tests is still a key component of the diagnostic algorithm of NAFLD. The aim of this study is to assess the concordance between the FIB-4 and liver stiffness measurement (LSM) in patients referred to two liver centers for the ultrasound-based diagnosis of NAFLD. Fibrosis 4 Index for Liver Fibrosis (FIB-4) and LSM were assessed in 1338 patients. A total of 428 (32%) had an LSM ≥ 8 kPa, whereas 699 (52%) and 113 (9%) patients had an FIB-4 < 1.3 and >3.25, respectively. Among 699 patients with an FIB-4 < 1.3, 118 (17%) had an LSM ≥ 8 kPa (false-negative FIB-4). This proportion was higher in patients ≥60 years, with diabetes mellitus (DM), arterial hypertension or a body mass index (BMI) ≥ 27 kg/m2. In multiple adjusted models, age ≥ 60 years (odds ratio (OR) = 1.96, 95% confidence interval (CI) 1.19−3.23)), DM (OR = 2.59, 95% CI 1.63−4.13), body mass index (BMI) ≥ 27 kg/m2 (OR = 2.17, 95% CI 1.33−3.56) and gamma-glutamyltransferase ≥ 25 UI/L (OR = 2.68, 95% CI 1.49−4.84) were associated with false-negative FIB-4. The proportion of false-negative FIB-4 was 6% in patients with none or one of these risk factors and increased to 16, 31 and 46% among those with two, three and four concomitant risk factors, respectively. FIB-4 is suboptimal to identify patients to refer to liver centers, because about one-fifth may be false negative at FIB-4, having instead an LSM ≥ 8 KPa.

This uniquely long-term follow up confirms the results of previous analyses, namely the lack of association between exposure to talc with no detectable level of asbestos and lung cancer and mesothelioma. Increased mortality from pneumoconiosis among miners is related to past exposure to silica.

Background: Diabetes mellitus is a dramatic epidemic worldwide. This study providea an updated estimate of itsprevalence and determinants among Italian adults. Methods: Data were derived from a face-to-face survey conducted in 2013 on 2901 individuals (1391 men, 1510 women) aged ≥18 years, representative of the general adult Italian population. Odds ratios (OR) for diabetes versus non diabetes in relation to selected risk factors were derived using multiple logistic regression models. Results: Overall, 135 out of 2901 adults (4.7%) reported a diagnosis of diabetes, with similar prevalence in men (4.8%) and in women (4.5%). Diabetes increased with age (0.6% at age 18-44, 5.1% at age 45-64, and 11.3% at age ≥65 years; p-trend &lt;0.001) and decreased with increasing level of education (12.8% for low, 7.8% for middle, and 1.4% for high education; p-trend &lt;0.001). Prevalence was higher among obese subjects (10.8%) compared to normal weight subjects (3.1%; OR=2.46; p-trend=0.001), among individuals reporting a physical activity &lt;30 minutes of walk/day (5.6%) compared to those reporting &gt;60 minutes of walk/day (3.8%; OR=1.43), and among ex-smokers (11.6%) compared to never smokers (4.2%; OR=2.51); moreover, it was lower among moderate drinkers (3.1%) than among abstainers (6.1%; OR=0.57; p-trend=0.016). Prevalence of diabetes was 16.1% in individuals with a diagnosis of hypertension (OR=4.66), 15.2% in those with high cholesterol (OR=3.84), and 21.6% among aspirin users (OR=4.46). Conclusion: Although diabetes prevalence in Italy is still comparatively low, effective clinical and preventive intervention strategies – focused on major risk behaviors – should be implemented to control the diffusion of this condition.

At present, analysis of diet and bladder cancer (BC) is mostly based on the intake of individual foods. The examination of food combinations provides a scope to deal with the complexity and unpredictability of the diet and aims to overcome the limitations of the study of nutrients and foods in isolation. This article aims to demonstrate the usability of supervised data mining methods to extract the food groups related to BC. In order to derive key food groups associated with BC risk, we applied the data mining technique C5.0 with 10-fold cross-validation in the BLadder cancer Epidemiology and Nutritional Determinants study, including data from eighteen case-control and one nested case-cohort study, compromising 8320 BC cases out of 31 551 participants. Dietary data, on the eleven main food groups of the Eurocode 2 Core classification codebook, and relevant non-diet data (i.e. sex, age and smoking status) were available. Primarily, five key food groups were extracted; in order of importance, beverages (non-milk); grains and grain products; vegetables and vegetable products; fats, oils and their products; meats and meat products were associated with BC risk. Since these food groups are corresponded with previously proposed BC-related dietary factors, data mining seems to be a promising technique in the field of nutritional epidemiology and deserves further examination.
