Abstract
We investigated the possibility to use rapeseed as a main oil in ice cream formulations by changing its functionality when using different kinds of lipases. Through a 24 h-emulsification and a centrifugation, the modified oils were further used as functional ingredients. All lipolysis was first assessed as a function of time by 13C NMR, where triglycerides consumption and the formation of low-molecular polar lipids (LMPL: monoacylglycerol and free fatty acids, FFAs) were selectively identified and compared. The more the FFAs, the sooner the crystallization (from -55 to -10 °C) and the later the melting temperatures (from -17 to 6 °C) measured by differential scanning calorimetry. These modifications were exploited in ice cream formulations with a significant impact on overall hardness (range of 60-216 N) and flowing during defrosting (from 1.29 to 0.35g/min). The global behavior of products can be controlled by the composition of LMPL within oil.

Abstract
Abstract
Background
Glioblastoma (GB) is the most severe form of brain cancer, with a 12-15 month median survival. Although cell therapies for GB are on the near horizon, surgical resection, temozolomide (TMZ) and radiotherapy (RT) remain the primary therapeutic options for GB, and no new small-molecule therapies have been introduced in recent years. This therapeutic standstill is partially because preclinical models of GB do not reflect the complexities of GB cell biology. Furthermore, the aggressive progression of GB makes it critical to identify patient-tailored therapeutic strategies early.
Material and Methods
We developed a novel in-vitro 3D glioblastoma explants (GB-EXPs) model derived from patients’ resected tumors maintaining cytoarchitecture seen in the tumors. We then performed metabolic-imaging by fluorescence lifetime imaging microscopy (FLIM) on live GB-EXPs to predict drug response, using TMZ as test drug.
Results
The entire process was successfully completed within 1 week since surgery. A unique drug response sample stratification emerged that was well reflected at the molecular level, highlighting new targets associated with TMZ treatment and identifying a molecular signature associated with survival.
Conclusion
To the best of our knowledge, this is the first time that FLIM-based metabolic imaging is used on live glioblastoma explants to test anti-neoplastic drugs. FLIM-based readouts of drug response in GB explants could accelerate precision treatment of patients with GB and the identification of new anti-GB drugs.

Abstract
Abstract
Background
Circulating Tumor Cells (CTCs) are considered to be one of the important causes of tumor recurrence and distant metastasis. For many years, glioblastoma (GB) was thought to be restricted to the brain. Nevertheless, a growing body of evidence indicates that, like many other cancers, hematogenic dissemination is a reality. The absence of a procedural uniformity in literature prompted us to develop an innovative and sensitive method to obtain CTCs in GB. Our aim is to define the genetic background of single CTCs compared with the primary GB tumor and its recurrence to assess whether or not their presence in the peripheral circulation correlates with GB migration and dissemination.
Material and Methods
CTCs were enriched from whole blood of one patient with recurrent GB with Parsortix Cell Separation System and analysed on DEPArray system. After that, CTCs Copy Number Aberrations (CNAs) and sequencing analysis was performed to compare CTCs genetic background with the same patient’s primary and recurrence tissues, analysed by NextSeq 500 (whole exome sequencing).
Results
We obtained 211 mutations in common between primary and recurrence tumor. Among these, three somatic mutations (c.430 G>A in PRKCB gene, c.815 C>T in TBX1 gene and c.1554 T>G in COG5 gene) were selected to investigate their presence in recurrence CTCs. Almost all of the sorted CTCs (9/13) had at least one of the mutations tested.
Conclusion
In confirmation of the hypothesis, the CTCs detected in the patient's blood were actually cancer cells deriving from GB tumor.

Abstract
Commercial oleogelators rich in monoglycerides (MGs) are complex mixtures of acylglycerides with variable gelling properties, depending on the oil used and their concentration. In this study we developed a chemometric approach to identify the key parameters involved in gelling process. Analytical parameters have been defined, using GC and NMR analysis to identify fatty acids and acylglycerides composing the mixtures. Specific acylglyceride families and compound ratios were calculated to streamline the analytical results. To determine the key analytical parameters, artificial neural networks were used in a QSPR study related to the gelling properties measured by rheology through oscillatory experiments. At low oleogelator concentrations, the MGs especially rich in C16:0 and the ratio of specific isomers both have a positive influence on G'. For high oleogelator concentrations, C18:0-rich acylglycerides and unsaturated/saturated fatty acid ratios have a positive influence on G'. Conversely, at low concentrations, C18:0-rich acylglycerides show a lesser effect on G'.

Abstract
PURPOSE Evidence of an increased diagnostic pressure on thyroid has emerged over the past decades. This study aimed to provide estimates of a wide spectrum of surveillance indicators for thyroid dysfunctions and diseases in Italy. METHODS A population-based study was conducted in North-eastern Italy, including 11.7 million residents (20% of the total Italian population). Prescriptions for TSH testing, neck ultrasound or thyroid fine needle aspiration (FNA), surgical procedures, and drugs for hypo- or hyperthyroidism were extracted from regional health databases. Proportions and rates of selected examinations were calculated from 2010 to 2017, overall and by sex, calendar years, age, and region. RESULTS Between 2010 and 2017 in North-eastern Italy, 24.5% of women and 9.8% of men received at least one TSH test yearly. In 2017, 7.1% of women and 1.5% of men were prescribed drugs for thyroid dysfunction, 94.6% of whom for hypothyroidism. Neck ultrasound examinations were performed yearly in 6.9% of women and 4.6% of men, with a nearly two-fold variation between areas. Thyroid FNA and thyroidectomies were three-fold more frequent in women (394 and 85 per 100,000) than in men (128 and 29 per 100,000) with a marked variation between areas. Both procedures decreased consistently after 2013. CONCLUSIONS The results of this population-based study describe recent variations over time and between surrounding areas of indicators of 'diagnostic pressure' on thyroid in North-eastern Italy. These results emphasize the need to harmonize practices and to reduce some procedures (e.g., neck ultrasound and total thyroidectomies) in certain areas.

Abstract
PURPOSE The aim of the study was to evaluate organogel nanoparticles as a lipophilic vehicle to increase the oral bioavailability of poorly soluble compounds. Efavirenz (EFV), a Biopharmaceutical Classification System (BCS) Class II, was used as drug model. METHODS Organogel nanoparticles loaded with EFV were formulated with sunflower oil, 12-hydroxystearic acid (HSA) and polyvinyl alcohol (PVA). Various parameters have been investigated in the current study such as (i) the release profile of organogel assessed by USP 4 cell flow dialysis, (ii) the impact of organogel on intestinal absorption, using Caco-2 cells as in vitro model and jejunum segments as ex vivo assay and (iii) the bioavailability of organogel following oral pharmacokinetic study. RESULTS 250-300 nm spherical particles with a final concentration of 4.75 mg/mL drug loading were obtained, corresponding to a thousand fold increase in EFV solubility, combined to a very high encapsulation efficiency (>99.8%). Due to rapid diffusion, drug was immediately released from the nanoparticles. The biopharmaceutical evaluation on ex vivo jejunum segments demonstrated an increased absorption of EFV from organogel nanoparticles compare to a native EFV suspension. In vitro assays combining Caco-2 cell cultures with TEM and confocal microscopy demonstrated passive diffusion, while paracellular integrity and endocytosis activity remain expelled. Oral pharmacokinetics of EFV organogel nanoparticles improve oral bioavailability (Fr: 249%) and quick absorption compared to EFV suspension. CONCLUSION Organogel nanoparticles increase the bioavailability of BCS Class II drugs. The main phenomena is simply oil transfer from the gelled particles through the cell membrane.

Abstract
A hydrogel can be formed by an organogelator in the presence of a nanoemulsion. It is expected that this is due to a gelation transfer from oil to water. The system started with an oil-in-water nanoemulsion prepared according to a phase inversion temperature (PIT) process. Into this nanoemulsion consisting of Kolliphor® RH40 and Brij® L4 as surfactants, and Miglyol® 812 as oil and water, we introduced the organogelator 12-hydroxyoctadecanoic acid (12-HOA) in the oil phase. After cooling at room temperature, a slow reversible gelation of the water phase occurred with persistence of the nanoemulsion. This thermally reversible system was investigated using various techniques (rheology, turbidimetry, optical and electron microscopies, scattering techniques). Successive stages appeared during the cooling process after the nanoemulsion formation, corresponding to the migration and self-assembly of the organogelator from the oil nanodroplets to the water phase. According to our measurements and the known self-assembly of 12-HOA, a mechanism explaining the formation of the gelled nanoemulsion is proposed.

Abstract
Background Tumors develop by progression through a series of stages. Every cell of the tumor microenvironment is constantly changing in the flow of the cancer progression. It has become clear in recent years that stroma is essential for tumor maintenance and growth. Here, we aimed to give a chronological order of gene expression changes given in the dynamical framework of microinvasive breast cancer microenvironment. Methods RNA-seq was performed on seven microinvasive breast cancers. For each of them we microdissected seven different portions of the tumor, four related to the breast epithelium and three to the stroma. Breast epithelium was chronologically subdivided in normal breast epithelium (NBE), carcinoma in situ (CIS), emerging invasive fingers (EIF) and invasive breast cancer (IBC). For each of the breast epithelium subdivisions we collected the adjacent stroma (S): S-NBE, S-EIF and S-IBC. Results The overall differentially expressed genes (DEGs) in all the compartments were analysed and evaluated to understand the pathways involved in tumor progression. Then we analysed the DEGs of the epithelial and stromal portions in comparison with the normal portions. We observed that the stromal cells are necessary for the development and the maintenance of the tumor, especially in tumor progression. Moreover the most important genes involved in the main metabolic pathways were analysed and the communications within the different cell compartments were highlighted. Conclusions As a future perspective, a deeply study of the identified key genes, particularly in the stromal cells, will be crucial to develop an anticancer therapy that is undergoing a conversion from a cancer cell-centric strategy to a stroma-centric strategy, more genomically stable.

Abstract
Incident cases of large bowel cancer from the Swiss canton of Vaud over the period 1974–88 were analyzed in relation to the distribution of site by sex, age, marital status and detailed subsite. A total of 1,968 cases were registered in males and 1,958 in females, corresponding to overall age-standardized (world) rates of 32.2/100,000 males and 22.4/100,000 females. The frequency of ascending and transverse colon cancer was lower in males (18.2 % and 9.3 %) than in females (23.1 % and 10.0 %, respectively), but cancers of the sigmoid colon and rectum were proportionally more frequent in males (34.0 and 30.0 % versus 29.9 and 24.6 % in females). Anal cancer accounted for 4.0% of large bowel cancers in females, but only 1.2% in males. Analysis of age-specific rates showed comparable values for ascending colon cancer in both sexes and in relation to each subsequent age group, as well as in sigmoid and rectal cancers up to middle age, while a male excess for the latter cancers became evident after age 55. A female excess for anal cancer was apparent in any subsequent age group. Information on marital status was available on 2,398 deceased subjects. Never married cases occounted for 12.2 % of women and 8.1 % of males. The excess of unmarried women was somewhat larger in the colon than in the sigma and rectum groups, but there was no evidence of excess of never married females for anal cancer. These data confirm that there are appreciable inter-sex heterogeneities in the descriptive epidemiology of various subsites of large bowel cancer, as well as complex interactions between sex and age, which may be related to female hormone correlates of intestinal carcinogenesis. Whatever the main biological mechanism(s), these data show noticeable similarities for both sexes in the descriptive epidemiology of cancers arising in the left colon and rectum, but noticeable differences with the right colon. Even more substantial are the differences with anal cancer, which should be linked to its venereal correlates.

Abstract
The present study examined the pattern of presentation and diagnostic interval, i.e. number of months between first cancer symptom or sign and first medical visit, in 444 cases of urological cancer (122 of prostate cancer, 187 of bladder cancer and 135 of kidney cancer). The mean diagnostic interval was 7.6 months for prostate, 5.6 for bladder and 4.5 kidney cancer. A chance diagnosis, i.e. in absence of any symptom or sign, was reported by 16%, 8% and 18% of patients with cancer of the prostate, bladder and kidney respectively. We observed on significant differences in diagnostic intervals according to patients’ demographic, sociocultural, and lifestyle characteristics, or tumor stage. Better quantitative and qualitative data on the pattern and determinants of delay in cancer diagnosis are clearly warranted, and the present study, although largely negative, shows the possibility of using large-scale epidemiological Investigations for this purpose.

Abstract
Aims and background Substantial upward trends for skin cancer mortality have been observed in most European countries in the last two decades. The distinction, however, between cutaneous malignant melanoma (CMM) and non-melanomatous skin cancers on the basis of death certification is unreliable Methods In order to assess the trends of CMM, analysis of the specific code for CMM (International Classification of Disease VIII and IX:172) was coupled with analysis of total skin cancer mortality rates, standardized on the 1981 Italian Census population, at all ages and in selected age groups (15-44, 45-64 and 65-84 years). The analyses were carried out for the whole of Italy and for Friuli-Venezia Giulia (FVG), a region in North-East Italy with a high proportion of fair-complexioned individuals, elevated frequency of sunbathing, and especially good diagnostic standards. Results In 1985-89 skin cancer mortality rates in men at all ages, as compared to 1970-74, were 33% higher in Italy and 46% higher in FVG. In women, there was a rise of 22% in Italy and 94% in FVG. More marked upward trends were observed in young and middle aged adults, especially among women in FVG (over 300% increase). In absolute terms, approximately 3000 more Italians died from skin cancers in 1985-89 as compared to 1970-74, about half of them prematurely (i.e., < 65 years). CMM was mentioned in death certifications for skin cancer increasingly often in all age groups, particularly in FVG. Conclusions The analysis of mortality trends from skin cancer is consistent with a substantial rise of CMM-related deaths. The sensitivity of death certification with respect to CMM diagnosis is also increasing, especially in FVG. A public health strategy with the aim of reducing intermittent intense exposure to ultraviolet light, especially in children, is urgent in Italy as CMM represents one of the few causes of premature death with unfavorable trends.

Abstract
An excess of classic Kaposi's sarcoma (KS) in individuals of southern European ancestry has long been suspected and recently quantified in terms of age-standardized rates. In Italy and most notably in southern Italy for the period 1976-84, prior to the AIDS epidemic, KS incidence rates were two-to-three-fold higher than in the United States and Sweden and many ten-fold higher than in England and Wales and Australia. A high frequency of classic KS has also been documented in Israel and, in low-risk countries, in individuals born in southern Europe and the Middle East. Many infections have been suspected to play a role in the etiology of KS, including cytomegalovirus, malaria and, most recently, a new virus of the herpes family, identified in AIDS-associated and classic KS. The present review deals with epidemiologic data concerning KS in the Mediterranean and stresses the opportunity to combine the study of KS in AIDS as well as non-AIDS patients in order to shed light on this no longer rare disease.

Abstract
Several lines of biological evidence have suggested a relationship between the behaviour of melanocytes and cutaneous malignant melanoma (CMM) and the action of female hormones. The present overview, however, indicates that the effect of reproductive, menstrual and hormonal factors, including oral contraceptives, on onset and outcome of CMM must be very weak, if any. The only consistent findings which may suggest a role of female hormones on CMM seem to be: 1) a different distribution by anatomic site in men and women, and 2) a more favorable outcome of CMM in women as compared to men. Neither of them, however, necessarily implies a direct effect of female hormones on CMM.

Abstract
Diagnostic procedure, therapeutic care and degree of follow-up delivered to 1692 lung cancer patients over 2 years (1978–79) in 31 Italian hospitals were reviewed. The data show marked deficiencies in the various indicators analysed: staging by standard methods was recorded only in 13% of patients; reliable histocytologic classification in 54% of patients. A group of commonly accepted protocols was adopted as first-line therapy only in 49% of treated cases; 19% of patients were regularly followed according to standard programs, whereas 49% had been dropped without any information in the charts. Better performance, although not satisfactory, was found in hospitals with oncologic facilities and wards compared to centers without « ad hoc » organizations. The discussion focussed on the limits of organizational measures and efforts to determine widespread improvement in care for a disease such as lung cancer for which real therapeutic gains are still hard to achieve.

Abstract
Information from published case-control studies on benign breast disease was pooled using standard statistical methods to obtain single, overall risk estimates. This analysis showed that higher socio-economic status (pooled relative risk, RR = 1.24, 95% confidence interval, CI = 1.13-1.37), later menopause (pooled RR = 1.87, 95%, CI = 1.67-2.11) and late age at first birth (pooled RR = 1.30, 95%, CI = 1.13-1.50) were associated with an increased risk of benign breast disease, whereas an apparent protection was given by greater body mass index (pooled RR = 0.58, 95%, CI = 0.50-0.67) and the use of oral contraceptives (pooled RR = 0.75, 95%, CI = 0.67-0.83). The role of these factors did not appear to be materially different in the various histopathologic categories considered, although available information allowed only a general distinction between breast dysplasia (fibrocystic disease) and benign tumors, chiefly fibroadenoma. In conclusion, the general evidence from published studies indicates that benign breast lumps appear to share a number of important risk factors with breast cancer.

Abstract
A positive association between the use of oral contraceptives and the risk of cervical neoplasia has been suggested by different sources. This paper examines epidemiologic evidence on this issue through pooled computation of relative risks emerging from 21 studies, subdivided into three main categories: studies based on routine cytologic screening programs, case-control investigations and prospective studies. The pooled estimates of the relative risks for ever vs never use of oral contraceptives were broadly similar and slightly above unity (1.4 from cytologic screening programs, 1.1 from case-control and 1.4 from prospective studies). The risk increased with duration of use and, generally, lower relative risk estimates derived from the older studies, necessarily based on short-term use of oral contraceptives. A particularly limited increase in risk was apparent from case-control investigations. Furthermore, when allowance was made for the major covariates (mostly indicators of sexual habits), a noticeable decrease in the excess risk was evident. In conclusion, although statistical significance of moderate differences in risk can be obtained by pooling data from several studies, a risk of the magnitude of that for the association between oral contraceptives and cervical neoplasia may well be due to bias and confounding. In addition, since sexual behavior only indicates the probability of having been exposed to some sexually transmitted agent (most likely human papilloma virus), the greatest additional contribution may come from a case-control study in which adjustment for such exposure is possible.

Abstract
Enhanced secretion of thyroid stimulating hormone (TSH) has been linked with increased risk of thyroid carcinoma. Diet can increase TSH secretion in various ways: 1) low iodine intake, 2) high goitrogen intake, especially in subjects living in iodine-deficiency areas and 3) direct stimulation of anterior pituitary gland. Excessive iodine intake, however, has also been shown to increase risk of goitre and, perhaps, also thyroid carcinoma. Epidemiological evidence on the role of diet in the etiology of thyroid carcinoma is reviewed here. Ad hoc studies in affluent countries are few and often conflicting. A case-control study conducted in the North of Italy suggests that perhaps dietary aspects other than iodine or goitrogens (i.e. fresh fruit and vegetables and animal fat) may be involved.

Abstract
Aims and background The risk for several cancers is higher in urban than in rural areas. The gradient has seldom been studied in southern Europe. Patients and methods The geographical pattern of mortality for different cancers and all causes was studied in the Campania Region (about 5.6 million inhabitants), whose largest town is Naples. The key variables were residence in urban/rural and coastal/inland municipalities. Relative risks of death and corresponding 95% confidence intervals by residence were evaluated by means of Poisson log-linear regression models. Results Significantly increased mortality rates in urban compared to rural municipalities were found for several cancer causes of death. In particular, in both sexes, excesses in the order of 30-50% were observed for tobacco-related neoplasms (i.e., larynx, lung, and bladder) and cancers of the intestine, liver, brain, multiple myeloma and non-Hodgkin's lymphoma, in addition to all-cancer, and all-cause mortality. In females, specific excesses were also noticed for cancer of the gallbladder, pancreas, breast and uterus (corpus and cervix). Conversely, significantly decreased mortality rates in urban with respect to rural municipalities were observed for cancer of the oral cavity and pharynx in males. Coastal location and degree of urbanization were strongly correlated, thus showing similar associations with most causes of death. However, a significant excess of cancer of the pleura in males was restricted to coastal municipalities. Conclusions Anti-smoking campaigns, sanitation improvements, hepatitis B vaccination, and a decrease in obesity emerge as high priorities with respect to cancer control strategies in the Campania Region, particularly in overpopu-lated, underprivileged urban areas.

Abstract
The purpose of the study was to evaluate organogel nanoparticles as a drug delivery system by investigating their stability, according to the formulation strategy, and their release profile. The gelled nanoparticles were prepared by hot emulsification (above the gelation temperature) of an organogel in water, and cooling at room temperature. In the first step, we used DLS and DSC to select the most suitable formulations by optimizing the proportion of ingredients (HSA, PVA, castor oil) to obtain particles of the smallest size and greatest stability. Then, two lipophilic drug models, indomethacin and ketoconazole were entrapped in the nanoparticles made of castor oil gelled by 12-hydroxystearic acid. Thermal studies (DSC) confirmed that there was no significant alteration of gelling due to the entrapped drugs, even at 3% w/w. Very stable dispersions were obtained (>3 months), with gelled oil nanoparticles presenting a mean diameter between 250 and 300 nm. High encapsulation efficiency (>98%) was measured for indomethacin and ketoconazole. The release profile determined by in vitro dialysis showed an immediate release of the drug from the organogel nanoparticles, due to rapid diffusion. The study demonstrates the interest of these gelled oil nanoparticles for the encapsulation and the delivery of lipophilic active compounds.

Abstract
We consider a Brownian motion with negative drift in the quarter plane with orthogonal reflection on the axes. The Laplace transform of its stationary distribution satisfies a functional equation, which is reminiscent from equations arising in the enumeration of (discrete) quadrant walks. We develop a Tutte’s invariant approach to this continuous setting, and we obtain an explicit formula for the Laplace transform in terms of generalized Chebyshev polynomials.

Abstract
BACKGROUND Poor oral hygiene has been proposed to contribute to head and neck cancer (HNC) risk, although causality and independency of some indicators are uncertain. This study investigates the relationship of five oral hygiene indicators with incident HNCs. METHODS In a pooled analysis of 8925 HNC cases and 12 527 controls from 13 studies participating in the International Head and Neck Cancer Epidemiology Consortium, comparable data on good oral hygiene indicators were harmonized. These included: no denture wear, no gum disease (or bleeding), <5 missing teeth, tooth brushing at least daily, and visiting a dentist ≥once a year. Logistic regression was used to estimate the effects of each oral hygiene indicator and cumulative score on HNC risk, adjusting for tobacco smoking and alcohol consumption. RESULTS Inverse associations with any HNC, in the hypothesized direction, were observed for <5 missing teeth [odds ratio (OR) = 0.78; 95% confidence interval (CI) 0.74, 0.82], annual dentist visit (OR = 0.82; 95% CI 0.78, 0.87), daily tooth brushing (OR = 0.83, 95% CI 0.79, 0.88), and no gum disease (OR = 0.94; 95% CI 0.89, 0.99), and no association was observed for wearing dentures. These associations were relatively consistent across specific cancer sites, especially for tooth brushing and dentist visits. The population attributable fraction for ≤ 2 out of 5 good oral hygiene indicators was 8.9% (95% CI 3.3%, 14%) for oral cavity cancer. CONCLUSION Good oral hygiene, as characterized by few missing teeth, annual dentist visits, and daily tooth brushing, may modestly reduce the risk of HNC.

Abstract
Abstract
Background. Tumors develop by progression through a series of stages. It is now widely accepted that cancer is attributed to the accumulation of genetic alterations in cells. Every cells of the tumor microenvironment is constantly changing in the flow of the cancer progression. A number of genes have been identified as having functions in various stages of progression in promoting cancer progression in experimental models. However, the association between gene expression alterations and resulting phenotypic alterations with respect to the aggressiveness and migration potential of cancer cells is not fully understood. Therefore, elucidation of genotype–phenotype correlation will be required to further understand the complex process of progression and invasion. All tumors require at least some stroma to meet their needs of nutrition, waste removal, and structure. It has become clear in recent years that stroma is essential for tumor maintenance and growth and has potential as a therapeutic target. Here, we aimed to give a chronological order of gene expression changes given in the dynamical framework of microinvasive breast cancer microenvironment.
Materials and Methods. RNA-seq (Ion Proton technology) was performed on three microinvasive breast cancers, applying new modifications to the usual protocol. For each of them we microdissected 7 different portions of the tumor (around 200 cells), 4 related to the breast epithelium and 3 to the stroma. The regions were selected on the basis of their grade of progression. Breast epithelium was chronologically subdivided in normal breast epithelium (NBE), carcinoma in situ (CIS), emerging invasive fingers (EIF) and invasive breast cancer (IBC). For each of the breast epithelium subdivisions we collected the adjacent stroma (S) except for the in situ portion: S-NBE, S-EIF and S-IBC.
Results: Whole transcriptome analysis performed on each microdissected regions reveals a series of gene expression changes occurring during cancer progression in the breast epithelium along with the adjacent stroma. The dendogram analysis, based on the whole gene expression data of each patient revealed a perfect group organization of the various microdissected portions of stroma and mammary epithelium. Within the dendogram, the organization of Normal, In Situ, EIF and Invasive tissue respected perfectly the biological assumptions.
Conclusions: More thorough analyses are needed to give a clear view of the flow of molecular events starting from the normal breast epithelium to the microinvasive stage, as well as to give a better understanding of the stroma-epithelium molecular means of communication. The analysis of all the molecular changes occuring in the breast epithelium and in the stroma of microinvasive cancer could lead to the development of new therapeutic targets.

Abstract
BACKGROUND Nordic countries' data offer a unique possibility to evaluate the long-term benefit of cervical cancer screening in a context of increasing risk of human papillomavirus infection. METHODS Ad hoc-refined age-period-cohort models were applied to the last 50-year incidence data from Denmark, Finland, Norway and Sweden to project expected cervical cancer cases in a no-screening scenario. RESULTS In the absence of screening, projected incidence rates for 2006-2010 in Nordic countries would have been between 3 and 5 times higher than observed rates. Over 60,000 cases or between 41 and 49% of the expected cases of cervical cancer may have been prevented by the introduction of screening in the late 1960s and early 1970s. CONCLUSIONS Our study suggests that screening programmes might have prevented a HPV-driven epidemic of cervical cancer in Nordic countries. According to extrapolations from cohort effects, cervical cancer incidence rates in the Nordic countries would have been otherwise comparable to the highest incidence rates currently detected in low-income countries.

Abstract
BACKGROUND Carbohydrate foods with high glycemic and insulinemic potential may influence cancer risk possibly through the insulin/growth-factor axis. Two staple carbohydrate foods of the Mediterranean diet, bread and pasta, have different glycemic and insulinemic responses and hence may affect cancer risk differently. MATERIALS AND METHODS We studied the association of bread and pasta with breast and colorectal cancer risk using data from two Italian case-control studies. These studies included 2569 women with histologically confirmed breast cancer and 1953 men and women with colorectal cancer. Controls were 2588 and 4154, respectively, admitted to the same hospitals as cases for acute, non-neoplastic conditions. Multivariate odds ratios (ORs) were obtained after allowance for relevant confounding factors. RESULTS The ORs of breast cancer for the highest versus the lowest quintile were 1.28 (95% confidence interval, CI: 1.03-1.58, P-trend = 0.0342) for bread and 1.07 (95% CI: 0.88-1.31, P-trend = 0.7072) for pasta. The association with bread remained virtually unchanged with postmenopause and overweight. The ORs of colorectal cancer in women for the highest versus the lowest quintile were 2.02 (95% CI: 1.46-2.80, P-trend = 0.0002) for bread and 1.37 (95% CI: 1.00-1.88, P-trend = 0.0164) for pasta. The associations remained significant only for bread in strata of menopausal status and in women with overweight. No significant associations were seen in men for either bread or pasta. CONCLUSIONS Overall, these two cancer case-control studies showed stronger positive associations with bread than pasta in women, particularly if overweight, suggesting possible hormonal-related mechanisms.

Abstract
BACKGROUND Consumption of red meat has been related to increased risk of several cancers. Cooking methods could modify the magnitude of this association, as production of chemicals depends on the temperature and duration of cooking. METHODS We analyzed data from a network of case-control studies conducted in Italy and Switzerland between 1991 and 2009. The studies included 1465 oral and pharyngeal, 198 nasopharyngeal, 851 laryngeal, 505 esophageal, 230 stomach, 1463 colon, 927 rectal, 326 pancreatic, 3034 breast, 454 endometrial, 1031 ovarian, 1294 prostate and 767 renal cancer cases. Controls included 11 656 patients admitted for acute, non-neoplastic conditions. Odds ratios (ORs) and confidence intervals (CIs) were estimated by multiple logistic regression models, adjusted for known confounding factors. RESULTS Daily intake of red meat was significantly associated with the risk of cancer of the oral cavity and pharynx (OR for increase of 50 g/day = 1.38; 95% CI: 1.26-1.52), nasopharynx (OR = 1.29; 95% CI: 1.04-1.60), larynx (OR = 1.46; 95% CI: 1.30-1.64), esophagus (OR = 1.46; 95% CI: 1.23-1.72), colon (OR = 1.17; 95% CI: 1.08-1.26), rectum (OR = 1.22; 95% CI:1.11-1.33), pancreas (OR = 1.51; 95% CI: 1.25-1.82), breast (OR = 1.12; 95% CI: 1.04-1.19), endometrium (OR = 1.30; 95% CI: 1.10-1.55) and ovary (OR = 1.29; 95% CI: 1.16-1.43). Fried meat was associated with a higher risk of cancer of oral cavity and pharynx (OR = 2.80; 95% CI: 2.02-3.89) and esophagus (OR = 4.52; 95% CI: 2.50-8.18). Risk of prostate cancer increased for meat cooked by roasting/grilling (OR = 1.31; 95% CI: 1.12-1.54). No heterogeneity according to cooking methods emerged for other cancers. Nonetheless, significant associations with boiled/stewed meat also emerged for cancer of the nasopharynx (OR = 1.97; 95% CI: 1.30-3.00) and stomach (OR = 1.86; 95% CI: 1.20-2.87). CONCLUSIONS Our analysis confirmed red meat consumption as a risk factor for several cancer sites, with a limited impact of cooking methods. These findings, thus, call for a limitation of its consumption in populations of Western countries.

Abstract
BACKGROUND The risk of many cancers is higher in subjects with a family history (FH) of cancer at a concordant site. However, few studies investigated FH of cancer at discordant sites. PATIENTS AND METHODS This study is based on a network of Italian and Swiss case-control studies on 13 cancer sites conducted between 1991 and 2009, and including more than 12 000 cases and 11 000 controls. We collected information on history of any cancer in first degree relatives, and age at diagnosis. Odds ratios (ORs) for FH were calculated by multiple logistic regression models, adjusted for major confounding factors. RESULTS All sites showed an excess risk in relation to FH of cancer at the same site. Increased risks were also found for oral and pharyngeal cancer and FH of laryngeal cancer (OR = 3.3), esophageal cancer and FH of oral and pharyngeal cancer (OR = 4.1), breast cancer and FH of colorectal cancer (OR = 1.5) and of hemolymphopoietic cancers (OR = 1.7), ovarian cancer and FH of breast cancer (OR = 2.3), and prostate cancer and FH of bladder cancer (OR = 3.4). For most cancer sites, the association with FH was stronger when the proband was affected at age <60 years. CONCLUSIONS Our results point to several potential cancer syndromes that appear among close relatives and may indicate the presence of genetic factors influencing multiple cancer sites.

Abstract
BACKGROUND Factors that favour a small proportion of HPV16 infections to progress to cancer are still poorly understood, but several studies have implicated a role of HPV16 genetic variation. METHODS To evaluate the association between HPV16 genetic variants and cervical cancer risk, we designed a multicentre case-control study based on HPV16-positive cervical samples (1121 cervical cancer cases and 400 controls) from the International Agency for Research on Cancer biobank. By sequencing the E6 gene, HPV16 isolates were classified into variant lineages and the European (EUR)-lineage isolates were subclassified by the common polymorphism T350G. RESULTS Incidence of variant lineages differed between cases and controls in Europe/Central Asia (P=0.006, driven by an underrepresentation of African lineages in cases), and South/Central America (P=0.056, driven by an overrepresentation of Asian American/North American lineages in cases). EUR-350G isolates were significantly underrepresented in cervical cancer in East Asia (odds ratio (OR)=0.02 vs EUR-350T; 95% confidence interval (CI)=0.00-0.37) and Europe/Central Asia (OR=0.42; 95% CI=0.27-0.64), whereas the opposite was true in South/Central America (OR=4.69; 95% CI=2.07-10.66). CONCLUSION We observed that the distribution of HPV16 variants worldwide, and their relative risks for cervical cancer appear to be population-dependent.

Abstract
Background: We assessed the association of human papillomavirus (HPV) infection and cervical intraepithelial neoplasia (CIN) with various characteristics, CD4 count and use of combination antiretroviral therapy (cART) among HIV-positive women. Methods: Cross-sectional study of 498 HIV-positive women who underwent HPV PCR-based testing, cytology, and systematic cervical biopsy. Results: In all, 68.7% of women were HPV-positive, 52.6% had high-risk (hr) HPV, and 40.2% multiple type infections. High-risk human papillomavirus-positivity did not vary significantly by age but it was negatively associated with education level. The most frequent types in 113 CIN2/3 were HPV16 (26.5%), HPV35 (19.5%), and HPV58 (12.4%). CD4 count was negatively associated with prevalence of hrHPV (P<0.001) and CIN2/3 among non-users of cART (P=0.013). Combination antiretroviral therapies users (⩾2 year) had lower hrHPV prevalence (prevalence ratio (PR) vs non-users=0.77, 95% confidence interval (CI): 0.61–0.96) and multiple infections (PR=0.68, 95% CI: 0.53–0.88), but not fewer CIN2/3. The positive predictive value of hrHPV-positivity for CIN2/3 increased from 28.9% at age <35 years to 53.3% in ⩾45 years. Conclusion: The burden of hrHPV and CIN2/3 was high and it was related to immunosuppression level. Combination antiretroviral therapies ( ⩾2 year) use had a favourable effect on hrHPV prevalence but cART in our population may have been started too late to prevent CIN2/3.

Abstract
Background: Dietary habits have been related to the risk of nasopharyngeal carcinoma (NPC), but information on a wide range of macro- and micronutrients is still lacking, particularly for low-incidence countries. Methods: We conducted a hospital-based case–control study in Italy on 198, histologically confirmed, NPC cases of Caucasian ethnicity of 18–76 years of age. Controls were 594 Caucasian cancer-free patients admitted to general hospitals for acute conditions. Nutrients intake was assessed through a validated food-frequency questionnaire. Adjusted odds ratios (ORs) and the corresponding confidence intervals (CIs) were estimated through logistic regression. Results: Dietary intake of carotenoids were inversely related to NPC risk, notably carotene (OR for highest vs lowest quartile=0.46; 95% CI: 0.26–0.79), α-carotene (OR=0.57; 95% CI: 0.33–0.97), and β-carotene (OR=0.42; 95% CI: 0.24–0.75). Increased NPC risk was observed for elevate cholesterol intake (OR=1.85; 95% CI: 1.12–3.05). Conclusion: Study findings suggest a protective effect of carotenoids against NPC in a low-risk population, adding further support to a possible beneficial role of a diet rich in fruits and vegetables in cancers of the head and neck.

Abstract
BACKGROUND Folate deficiency leads to DNA damage and inadequate repair, caused by a decreased synthesis of thymidylate and purines. We analyzed the relationship between dietary folate intake and the risk of several cancers. PATIENTS AND METHODS The study is based on a network of case-control studies conducted in Italy and Switzerland in 1991-2009. The odds ratios (ORs) for dietary folate intake were estimated by multiple logistic regression models, adjusted for major identified confounding factors. RESULTS For a few cancer sites, we found a significant inverse relation, with ORs for an increment of 100 μg/day of dietary folate of 0.65 for oropharyngeal (1467 cases), 0.58 for esophageal (505 cases), 0.83 for colorectal (2390 cases), 0.72 for pancreatic (326 cases), 0.67 for laryngeal (851 cases) and 0.87 for breast (3034 cases) cancers. The risk estimates were below unity, although not significantly, for cancers of the endometrium (OR = 0.87, 454 cases), ovary (OR = 0.86, 1031 cases), prostate (OR = 0.91, 1468 cases) and kidney (OR = 0.88, 767 cases), and was 1.00 for stomach cancer (230 cases). No material heterogeneity was found in strata of sex, age, smoking and alcohol drinking. CONCLUSIONS Our data support a real inverse association of dietary folate intake with the risk of several common cancers.

Abstract
BACKGROUND We analyzed the relationship between cholelithiasis and cancer risk in a network of case-control studies conducted in Italy and Switzerland in 1982-2009. METHODS The analyses included 1997 oropharyngeal, 917 esophageal, 999 gastric, 23 small intestinal, 3726 colorectal, 684 liver, 688 pancreatic, 1240 laryngeal, 6447 breast, 1458 endometrial, 2002 ovarian, 1582 prostate, 1125 renal cell, 741 bladder cancers, and 21 284 controls. The odds ratios (ORs) were estimated by multiple logistic regression models. RESULTS The ORs for subjects with history of cholelithiasis compared with those without were significantly elevated for small intestinal (OR=3.96), prostate (OR=1.36), and kidney cancers (OR=1.57). These positive associations were observed ≥10 years after diagnosis of cholelithiasis and were consistent across strata of age, sex, and body mass index. No relation was found with the other selected cancers. A meta-analysis including this and three other studies on the relation of cholelithiasis with small intestinal cancer gave a pooled relative risk of 2.35 [95% confidence interval (CI) 1.82-3.03]. CONCLUSION In subjects with cholelithiasis, we showed an appreciably increased risk of small intestinal cancer and suggested a moderate increased risk of prostate and kidney cancers. We found no material association with the other cancers considered.
