Mild anemia and 11- to 15-year mortality risk in young-old and old-old: Results from two population-based cohort studies.

BACKGROUND: Mild anemia is a frequent although often overlooked finding in old age. Nevertheless, in recent years anemia has been linked to several adverse outcomes in the elderly population. Objective of the study was to investigate the association of mild anemia (hemoglobin concentrations: 10.0-11.9/12.9 g/dL in women/men) with all-cause mortality over 11-15 years and the effect of change in anemia status on mortality in young-old (65-84 years) and old-old (80+ years). METHODS: The Health and Anemia and Monzino 80-plus are two door-to-door, prospective population-based studies that included residents aged 65-plus years in Biella municipality and 80-plus years in Varese province, Italy. No exclusion criteria were used. RESULTS: Among 4,494 young-old and 1,842 old-old, mortality risk over 15/11 years was significantly higher in individuals with mild anemia compared with those without (young-old: fully-adjusted HR: 1.35, 95%CI, 1.15-1.58; old-old: fully-adjusted HR: 1.28, 95%CI, 1.14-1.44). Results were similar in the disease-free subpopulation (age, sex, education, smoking history, and alcohol consumption adjusted HR: 1.54, 95%CI, 1.02-2.34). Both age groups showed a dose-response relationship between anemia severity and mortality (P for trend <0.0001). Mortality risk was significantly associated with chronic disease and chronic kidney disease mild anemia in both age groups, and with vitamin B12/folate deficiency and unexplained mild anemia in young-old. In participants with two hemoglobin determinations, seven-year mortality risk was significantly higher in incident and persistent anemic cases compared to constant non-anemic individuals in both age groups. In participants without anemia at baseline also hemoglobin decline was significantly associated with an increased mortality risk over seven years in both young-old and old-old. Limited to the Monzino 80-plus study, the association remained significant also when the risk was further adjusted also for time-varying covariates and time-varying anemia status over time. CONCLUSIONS: Findings from these two large prospective population-based studies consistently suggest an independent, long-term impact of mild anemia on survival at older ages.

Association of renal function with cognition, functional ability and mood in the oldest-old: The 'Health and Anemia study'.

AIM: In this study, the relationship between kidney function, cognitive performance, functional abilities and mood was investigated in a community-dwelling Italian oldest-old population. METHODS: Serum creatinine was used to calculate estimated glomerular filtration rate (eGFR) using the Modification of Diet in Renal Disease formula, for 415 oldest-old without dementia participating in the 'Health and Anemia' study, a prospective, observational cohort study. The cross-sectional associations of kidney function with cognitive performance on several neuropsychological tests, basic and instrumental functional abilities and mood were analyzed using univariate and multivariable linear regression models. RESULTS: Cognitive performance and functional ability significantly worsened with decreasing kidney function. After adjusting for age, sex, education, comorbidity index of the Cumulative Illness Rating Scale (CIRS), body mass index, bone fracture and serum ferritin levels the associations of eGFR categories with basic and instrumental functional abilities continued to be statistically significant whereas that with global cognitive functions did not. No significant independent association was found between renal function and mood. CONCLUSIONS: Oldest-old with reduced kidney function showed greater basic and instrumental functional disabilities, while cognitive function, although decreased with decreasing eGFR, was no longer significantly associated with eGFR categories after adjusting for confounders.

Characteristics of people living in Italy after a cancer diagnosis in 2010 and projections to 2020.

BACKGROUND: Estimates of cancer prevalence are widely based on limited duration, often including patients living after a cancer diagnosis made in the previous 5 years and less frequently on complete prevalence (i.e., including all patients regardless of the time elapsed since diagnosis). This study aims to provide estimates of complete cancer prevalence in Italy by sex, age, and time since diagnosis for all cancers combined, and for selected cancer types. Projections were made up to 2020, overall and by time since diagnosis. METHODS: Data were from 27 Italian population-based cancer registries, covering 32% of the Italian population, able to provide at least 7 years of registration as of December 2009 and follow-up of vital status as of December 2013. The data were used to compute the limited-duration prevalence, in order to estimate the complete prevalence by means of the COMPREV software. RESULTS: In 2010, 2,637,975 persons were estimated to live in Italy after a cancer diagnosis, 1.2 million men and 1.4 million women, or 4.6% of the Italian population. A quarter of male prevalent cases had prostate cancer (n = 305,044), while 42% of prevalent women had breast cancer (n = 604,841). More than 1.5 million people (2.7% of Italians) were alive since 5 or more years after diagnosis and 20% since ≥15 years. It is projected that, in 2020 in Italy, there will be 3.6 million prevalent cancer cases (+ 37% vs 2010). The largest 10-year increases are foreseen for prostate (+ 85%) and for thyroid cancers (+ 79%), and for long-term survivors diagnosed since 20 or more years (+ 45%). Among the population aged ≥75 years, 22% will have had a previous cancer diagnosis. CONCLUSIONS: The number of persons living after a cancer diagnosis is estimated to rise of approximately 3% per year in Italy. The availability of detailed estimates and projections of the complete prevalence are intended to help the implementation of guidelines aimed to enhance the long-term follow-up of cancer survivors and to contribute their rehabilitation needs.

Survival of cancer patients in Italy. / La sopravvivenza dei pazienti oncologici in Italia.

OBJECTIVES: Population-based survival statistics are fundamental to assess the efficacy of services offered to improve cancer patients' prognosis. This study aims to update cancer survival estimates for the Italian population, as well as provide new measures, such as the crude probability of death, which takes into account the possibility of dying from causes other than cancer, and the change in life expectancy after a cancer diagnosis, to properly address various questions. RESULTS: The study includes 1,932,450 cancer cases detected by the Network of Italian Cancer Registries (AIRTUM) from 1994 to 2011 and provides estimates for 38 cancer sites and for allsites cancer. For most common cancers diagnosed from 2005 to 2009, age-standardized 5-year net survival was: colon-rectum - males 65%, females 65%; lung - males 15%, females 19%; breast 87%; prostate 91%. For cancer sites such as stomach, colon, rectum, lung, skin melanoma, breast, cervix, prostate, and kidney, 5-year net survival is consistent between Central and Northern Italy, while it is a few percentage points lower in Southern Italy. Funnel plots expose these differences more in detail by showing the survival estimates in 13 Italian regions. For all sites but skin, 5- and 10-year net survival increased by about 10 percentage points in men and 7 points in women from 1994 to 2011. DISCUSSION: Specific articles deal with results on solid and haematological malignancies, international comparisons and analysis of time trends of incidence, mortality, and survival in combination for key cancer sites, aiming to interpret overall progress in the control of cancer in Italy.

[Intercensal reconstruction of population and descriptive epidemiological measures in Italy: what is the impact on the cancer incidence rates?]. / La ricostruzione intercensuaria della popolazione e le misure di epidemiologia descrittiva in Italia: qual è l'impatto sui tassi di incidenza dei tumori?

OBJECTIVES: to test the effect on cancer incidence rates when using precensal computation (computed population) or intercensal reconstruction of population (reconstructed population). DESIGN: comparison between computed and reconstructed population by area and period in 2002-2011; evaluation of the effect on cancer rates using Italian cancer registries data. Setting e participants: population data from the Italian National Institute for Statistics, cancer data from Italian cancer registries; specific analysis involves data from Parma (Emilia-Romagna Region, Northern Italy) and Taranto (Apulia Region, Southern Italy) cancer registries. MAIN OUTCOME MEASURES: ratio between computed and reconstructed population by area, gender, age, and period; ratio between corresponding age-standardized incidence rates. RESULTS: Italian population estimates by precensal computation for years 2002-2011 was generally higher than that obtained by intercensal reconstruction especially in 2011, when this has been found in more than 86% of Italian Municipalities. In the same year a smaller proportion of Municipalities (11%) showed an inverse population ratio. Among the most populated Municipalities, the City of Milan showed the higher precensal to intercensal population ratio (1.076), while the City of Taranto showed the lower precensal to intercensal population ratio (0.956). The ratios between age standardized rates obtained with precensal population to those obtained with intercensal population show similar differences; in particular, for all cancer in males and females they were, respectively, 0.985 and 0.982 in the Province of Parma, 0.974 and 0.968 in the City of Parma, 1.023 and 1.013 in the Province of Taranto, and 1.08 and 1.051 in the City of Taranto. CONCLUSION: using precensal population as denominator for the year 2002- 2011 produces a remarkable distortion of both temporal trend and geographical comparisons. It is, therefore, necessary that researchers take into account this possible distortion when reporting descriptive measures in the years between the last two censuses in Italy.

Italian cancer figures--Report 2015: The burden of rare cancers in Italy.

OBJECTIVES: This collaborative study, based on data collected by the network of Italian Cancer Registries (AIRTUM), describes the burden of rare cancers in Italy. Estimated number of new rare cancer cases yearly diagnosed (incidence), proportion of patients alive after diagnosis (survival), and estimated number of people still alive after a new cancer diagnosis (prevalence) are provided for about 200 different cancer entities. MATERIALS AND METHODS: Data herein presented were provided by AIRTUM population- based cancer registries (CRs), covering nowadays 52% of the Italian population. This monograph uses the AIRTUM database (January 2015), which includes all malignant cancer cases diagnosed between 1976 and 2010. All cases are coded according to the International Classification of Diseases for Oncology (ICD-O-3). Data underwent standard quality checks (described in the AIRTUM data management protocol) and were checked against rare-cancer specific quality indicators proposed and published by RARECARE and HAEMACARE (www.rarecarenet.eu; www.haemacare.eu). The definition and list of rare cancers proposed by the RARECAREnet "Information Network on Rare Cancers" project were adopted: rare cancers are entities (defined as a combination of topographical and morphological codes of the ICD-O-3) having an incidence rate of less than 6 per 100,000 per year in the European population. This monograph presents 198 rare cancers grouped in 14 major groups. Crude incidence rates were estimated as the number of all new cancers occurring in 2000-2010 divided by the overall population at risk, for males and females (also for gender-specific tumours).The proportion of rare cancers out of the total cancers (rare and common) by site was also calculated. Incidence rates by sex and age are reported. The expected number of new cases in 2015 in Italy was estimated assuming the incidence in Italy to be the same as in the AIRTUM area. One- and 5-year relative survival estimates of cases aged 0-99 years diagnosed between 2000 and 2008 in the AIRTUM database, and followed up to 31 December 2009, were calculated using complete cohort survival analysis. To estimate the observed prevalence in Italy, incidence and follow-up data from 11 CRs for the period 1992-2006 were used, with a prevalence index date of 1 January 2007. Observed prevalence in the general population was disentangled by time prior to the reference date (≤2 years, 2-5 years, ≤15 years). To calculate the complete prevalence proportion at 1 January 2007 in Italy, the 15-year observed prevalence was corrected by the completeness index, in order to account for those cancer survivors diagnosed before the cancer registry activity started. The completeness index by cancer and age was obtained by means of statistical regression models, using incidence and survival data available in the European RARECAREnet data. RESULTS: In total, 339,403 tumours were included in the incidence analysis. The annual incidence rate (IR) of all 198 rare cancers in the period 2000-2010 was 147 per 100,000 per year, corresponding to about 89,000 new diagnoses in Italy each year, accounting for 25% of all cancer. Five cancers, rare at European level, were not rare in Italy because their IR was higher than 6 per 100,000; these tumours were: diffuse large B-cell lymphoma and squamous cell carcinoma of larynx (whose IRs in Italy were 7 per 100,000), multiple myeloma (IR: 8 per 100,000), hepatocellular carcinoma (IR: 9 per 100,000) and carcinoma of thyroid gland (IR: 14 per 100,000). Among the remaining 193 rare cancers, more than two thirds (No. 139) had an annual IR <0.5 per 100,000, accounting for about 7,100 new cancers cases; for 25 cancer types, the IR ranged between 0.5 and 1 per 100,000, accounting for about 10,000 new diagnoses; while for 29 cancer types the IR was between 1 and 6 per 100,000, accounting for about 41,000 new cancer cases. Among all rare cancers diagnosed in Italy, 7% were rare haematological diseases (IR: 41 per 100,000), 18% were solid rare cancers. Among the latter, the rare epithelial tumours of the digestive system were the most common (23%, IR: 26 per 100,000), followed by epithelial tumours of head and neck (17%, IR: 19) and rare cancers of the female genital system (17%, IR: 17), endocrine tumours (13% including thyroid carcinomas and less than 1% with an IR of 0.4 excluding thyroid carcinomas), sarcomas (8%, IR: 9 per 100,000), central nervous system tumours and rare epithelial tumours of the thoracic cavity (5%with an IR equal to 6 and 5 per 100,000, respectively). The remaining (rare male genital tumours, IR: 4 per 100,000; tumours of eye, IR: 0.7 per 100,000; neuroendocrine tumours, IR: 4 per 100,000; embryonal tumours, IR: 0.4 per 100,000; rare skin tumours and malignant melanoma of mucosae, IR: 0.8 per 100,000) each constituted <4% of all solid rare cancers. Patients with rare cancers were on average younger than those with common cancers. Essentially, all childhood cancers were rare, while after age 40 years, the common cancers (breast, prostate, colon, rectum, and lung) became increasingly more frequent. For 254,821 rare cancers diagnosed in 2000-2008, 5-year RS was on average 55%, lower than the corresponding figures for patients with common cancers (68%). RS was lower for rare cancers than for common cancers at 1 year and continued to diverge up to 3 years, while the gap remained constant from 3 to 5 years after diagnosis. For rare and common cancers, survival decreased with increasing age. Five-year RS was similar and high for both rare and common cancers up to 54 years; it decreased with age, especially after 54 years, with the elderly (75+ years) having a 37% and 20% lower survival than those aged 55-64 years for rare and common cancers, respectively. We estimated that about 900,000 people were alive in Italy with a previous diagnosis of a rare cancer in 2010 (prevalence). The highest prevalence was observed for rare haematological diseases (278 per 100,000) and rare tumours of the female genital system (265 per 100,000). Very low prevalence (<10 prt 100,000) was observed for rare epithelial skin cancers, for rare epithelial tumours of the digestive system and rare epithelial tumours of the thoracic cavity. COMMENTS: One in four cancers cases diagnosed in Italy is a rare cancer, in agreement with estimates of 24% calculated in Europe overall. In Italy, the group of all rare cancers combined, include 5 cancer types with an IR>6 per 100,000 in Italy, in particular thyroid cancer (IR: 14 per 100,000).The exclusion of thyroid carcinoma from rare cancers reduces the proportion of them in Italy in 2010 to 22%. Differences in incidence across population can be due to the different distribution of risk factors (whether environmental, lifestyle, occupational, or genetic), heterogeneous diagnostic intensity activity, as well as different diagnostic capacity; moreover heterogeneity in accuracy of registration may determine some minor differences in the account of rare cancers. Rare cancers had worse prognosis than common cancers at 1, 3, and 5 years from diagnosis. Differences between rare and common cancers were small 1 year after diagnosis, but survival for rare cancers declined more markedly thereafter, consistent with the idea that treatments for rare cancers are less effective than those for common cancers. However, differences in stage at diagnosis could not be excluded, as 1- and 3-year RS for rare cancers was lower than the corresponding figures for common cancers. Moreover, rare cancers include many cancer entities with a bad prognosis (5-year RS <50%): cancer of head and neck, oesophagus, small intestine, ovary, brain, biliary tract, liver, pleura, multiple myeloma, acute myeloid and lymphatic leukaemia; in contrast, most common cancer cases are breast, prostate, and colorectal cancers, which have a good prognosis. The high prevalence observed for rare haematological diseases and rare tumours of the female genital system is due to their high incidence (the majority of haematological diseases are rare and gynaecological cancers added up to fairly high incidence rates) and relatively good prognosis. The low prevalence of rare epithelial tumours of the digestive system was due to the low survival rates of the majority of tumours included in this group (oesophagus, stomach, small intestine, pancreas, and liver), regardless of the high incidence rate of rare epithelial cancers of these sites. This AIRTUM study confirms that rare cancers are a major public health problem in Italy and provides quantitative estimations, for the first time in Italy, to a problem long known to exist. This monograph provides detailed epidemiologic indicators for almost 200 rare cancers, the majority of which (72%) are very rare (IR<0.5 per 100,000). These data are of major interest for different stakeholders. Health care planners can find useful information herein to properly plan and think of how to reorganise health care services. Researchers now have numbers to design clinical trials considering alternative study designs and statistical approaches. Population-based cancer registries with good quality data are the best source of information to describe the rare cancer burden in a population.

Screening for colorectal cancer in Italy: 2011-2012 survey.

We utilised the IMPATTO study's archives to describe the 2000-2008 colorectal cancer (CRC) incidence rate trends in Italy, once screening programmes based on the faecal immunochemical test were implemented in different areas. Data on CRCs diagnosed in Italy from 2000 to 2008 in subjects aged 40-79 years were collected by 23 cancer registries. Incidence rate trends were evaluated as a whole and by macro-area (North-Centre and South-Islands), presence of a screening programme, sex, ten-year age class, anatomic site, stage at diagnosis, and pattern of diagnosis (screen-detected, non-screen-detected). The annual percent change (APC) of incidence rate trends, with 95% confidence intervals (95%CI), were computed. The study included 46,857 CRCs diagnosed in subjects aged 40-79 years, of which 2,806 were screen-detected. The incidence rates in the North-Centre were higher than in the South and on the Islands. During the study period, screening programmes had been implemented only in the North-Centre and had a significant effect on incidence rates, with an initial sharp increase in incidence, followed by a decrease that started in the 3rd-4th years of screening. These incidence rate trends were exclusively due to modifications in the rates of stage I cases. After screening programmes started, incidence increased in all anatomic sites, particularly in the distal colon. The differential figures introduced by the implementation of screening programmes warrant a continuous surveillance of CRC incidence and mortality trends to monitor the impact of screening at a national level.

Mortality Prediction in the Oldest Old with Five Different Equations to Estimate Glomerular Filtration Rate: The Health and Anemia Population-based Study.

BACKGROUND: Kidney function declines considerably with age, but little is known about its clinical significance in the oldest-old. OBJECTIVES: To study the association between reduced glomerular filtration rate (GFR) estimated according to five equations with mortality in the oldest-old. DESIGN: Prospective population-based study. SETTING: Municipality of Biella, Piedmont, Italy. PARTICIPANTS: 700 subjects aged 85 and older participating in the "Health and Anemia" Study in 2007-2008. MEASUREMENTS: GFR was estimated using five creatinine-based equations: the Cockcroft-Gault (C-G), Modification of Diet in Renal Disease (MDRD), MAYO Clinic, Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) and Berlin Initiative Study-1 (BIS-1). Survival analysis was used to study mortality in subjects with reduced eGFR (<60 mL/min/1.73 m(2)) compared to subjects with eGFR ≥ 60 mL/min/1.73 m(2). RESULTS: Prevalence of reduced GFR was 90.7% with the C-G, 48.1% with MDRD, 23.3% with MAYO, 53.6% with CKD-EPI and 84.4% with BIS-1. After adjustment for confounders, two-year mortality was significantly increased in subjects with reduced eGFR using BIS-1 and C-G equations (adjusted HRs: 2.88 and 3.30, respectively). Five-year mortality was significantly increased in subjects with eGFR <60 mL/min/1.73 m(2) using MAYO, CKD-EPI and, in a graduated fashion in reduced eGFR categories, MDRD. After 5 years, oldest old with an eGFR <30 mL/min/1.73 m(2) showed a significantly higher risk of death whichever equation was used (adjusted HRs between 2.04 and 2.70). CONCLUSION: In the oldest old, prevalence of reduced eGFR varies noticeably depending on the equation used. In this population, risk of mortality was significantly higher for reduced GFR estimated with the BIS-1 and C-G equations over the short term. Though after five years the MDRD appeared on the whole a more consistent predictor, differences in mortality prediction among equations over the long term were less apparent. Noteworthy, subjects with a severely reduced GFR were consistently at higher risk of death regardless of the equation used to estimate GFR.

Population-based method for investigating adherence to international recommendations for pathology reporting of primary cutaneous melanoma: Results of a EUROCARE-5 high resolution study.

AIM: Our study aim was to investigate the degree of adherence to international recommendations for cutaneous melanoma pathology reports at the population level by a EUROCARE high resolution study. METHODS: The availability of nine characteristics - predominant cell type, tumour-infiltrating lymphocytes, mitotic index, histological subtype, growth phase, Clark level, Breslow thickness, ulceration, and sentinel-node biopsy - was examined on pathology reports of a random sample of 636 cases diagnosed in 2003-2005 in seven Italian cancer registries: Biella, Ferrara, Firenze, Latina, Ragusa, Reggio Emilia, Romagna. The odds of having (versus not having) information for all four core characteristics (last four listed above) were estimated. RESULTS: Sentinel node biopsy was available most often, followed by Clark level, Breslow thickness, histological subtype and ulceration. Information on all nine characteristics was more often available in Biella and Ferrara (northern Italy) than elsewhere. Information on all four core items was available for 78% of cases. Odds of four-core-item availability were higher (than mean) in Biella and lower in Latina (centre) and Ragusa (south). CONCLUSIONS: The availability of information important for staging and management was good overall on pathology reports, but varied with geography. It is likely to be improved by wider dissemination of reporting guidelines and adoption of a standardised synoptic reporting system.

Survival after cancer in Italian persons with AIDS, 1986-2005: a population-based estimation.

BACKGROUND: Cancer survival in persons with AIDS (PWA) after introduction of antiretroviral therapies remains poorly characterized. The aim is to provide population-based estimates of cancer survival, overall and for the most important cancer types in PWA, and a comparison with persons without AIDS (non-PWA) affected by the same cancer. METHODS: PWA with cancer at AIDS diagnosis or thereafter were individually matched with non-PWA by type of cancer, sex, age, year of diagnosis, area of living, and, for lymphomas, histological subtype. Five-year observed survival and hazard ratios (HRs) of death in PWA versus non-PWA with 95% confidence intervals (CIs) were estimated. RESULTS: We included 2262 Italian PWA and 4602 non-PWA with cancer diagnosed during 1986-2005. Between 1986 and 1995, and 1996 and 2005, 5-year survival for all cancers in PWA improved from 12% to 41% and the corresponding HR versus non-PWA decreased from 5.1 (95% CI: 4.3 to 6.1) to 2.9 (95% CI: 2.6 to 3.3). During 1996-2005, HRs were 2.0 (95% CI: 1.4 to 2.9) for Kaposi sarcoma, 3.4 (95% CI: 2.9 to 4.1) for non-Hodgkin lymphoma, and 2.4 (95% CI: 1.4 to 4.0) for cervical cancer. HRs were 2.5 (95% CI: 2.1 to 3.1) for all non-AIDS-defining cancers, 5.9 (95% CI: 3.1 to 11.2) for Hodgkin lymphoma, and 7.3 (95% CI: 2.8 to 19.2) for nonmelanoma skin cancer. A ≤3-fold survival difference was found for cancers of the stomach, liver, anus, lung, brain, and the most aggressive lymphoma subtypes. CONCLUSIONS: The persisting, although narrowing, gap in cancer survival between PWA and non-PWA indicates the necessity of enhancing therapeutic approaches, so that PWA can be provided the same chances of survival observed in the general population, and improving cancer prevention and screening.

Disease presentation, treatment and survival for Italian colorectal cancer patients: a EUROCARE high resolution study.

We analysed presentation, treatment and survival in a representative population-based sample of 3753 Italian colorectal cancer cases, diagnosed 2003-05: 70% were >65 years, 44% stage I-II, 27% stage IV and 92% received surgery. Chemotherapy was given to 58% of stage III colon cases, radiotherapy to 25% of rectal cases. Four percent of surgical cases underwent endoscopic polypectomy, and in 57% ≥11 lymph nodes were examined. Five-year relative survival was good (60%), independent of sex and site. Adherence to treatment guidelines was satisfactory, but wider use of faecal blood testing and colonoscopy will anticipate stage at diagnosis and likely improve survival.

Estimates of cancer burden in Piedmont and Aosta Valley.

AIMS AND BACKGROUND: Cancer registration in Piedmont currently covers the city of Turin and the province of Biella, together representing 24% of the regional population. The objective of this paper is to provide estimates of the incidence and mortality rates and prevalence proportions for cancer of the lung, breast, cervix, prostate, colon-rectum and stomach and melanoma of the skin for 2012 and the time trends up to 2015 for the Piedmont and Aosta Valley regions. METHODS: The estimates were obtained by applying the MIAMOD method, a statistical back-calculation approach to derive incidence and prevalence figures starting from mortality and relative survival data. Published data from the Italian cancer registries were modeled in order to estimate the regional cancer survival. The MIAMOD estimates were also compared with those obtained by applying a method based on the mortality-incidence and prevalence-incidence ratios. RESULTS: The most frequently diagnosed cancers in absolute terms were prostate, colorectal, breast and lung cancer with about 5,000, 4,700, 3,300, and 2,900 new cases, respectively, in 2012. Incidence rates were rising for melanoma in both sexes and lung cancer in women, while they diminished for cervical and stomach cancer. For prostate cancer and male lung cancer the rates initially increased but were estimated to decrease in the most recent period. Colorectal cancer also increased up to the 1990s but was estimated to reach a plateau in the final years of estimation. Prevalence increased for all the considered cancers with the exception of cervical cancer. Mortality was declining for all considered cancers with the exception of lung cancer in women. CONCLUSIONS: Monitoring indicators of the cancer burden is crucial for setting priorities among possible health system activities in a limited-resource setting. Piedmont has long invested in organized, population-based screening programs: these will have to be extended and accompanied by greater efforts in primary prevention.

Relative and disease-free survival for breast cancer in relation to subtype: a population-based study.

PURPOSE: No population-based study has investigated breast cancer (BC) subtypes defined by including Ki67. The aim of this study was to evaluate the relative proportions of immunohistochemical subtypes and differences in relative and disease-free survival between subtypes, in relation to patient and other cancer characteristics in Italian BC patient. METHODS: Information on estrogen, progesterone, human epidermal growth factor (HER2), Ki67, and relapses was obtained for 3,381 cases, sampled randomly and anonymously from cases diagnosed in 2003-2005 in nine Italian cancer registries. Relative excess risks (RERs) of death and risks of relapse 5 years after diagnosis were estimated. RESULTS: Luminal A cancers were 42 % of the total, luminal B 27 %, luminal-HER2 14 %, triple-negative 11 %, and HER2-enriched 7 %. For non-metastatic (3,302) cases, 4 and 7 % developed locoregional and distant metastases, respectively. RERs of death and risks of relapse were significantly greater for all cancer subtypes than luminal A, particularly for triple-negative and HER2-enriched cancers, which were more frequent in women <40 years. CONCLUSIONS: Our population-based findings confirm that subtype is an independent prognostic factor for BC. Triple-negative and HER2-enriched subtypes would benefit from the development and wide application, respectively, of targeted treatments, which would also improve survival for younger patients.

Consistency and inconsistency in testing biomarkers in breast cancer. A GRELL study in cut-off variability in the Romance language countries.

PURPOSE: Biological markers are crucial factors in order to differentiate female breast cancers and to determine the right therapy. This study aims at evaluating whether testing for biomarkers for female breast cancer has similar frequency and characteristics across and within countries. METHODS: Population-based cancer registries of the Association for cancer registration and epidemiology in Romance language countries (GRELL) were asked to complete a questionnaire on biomarkers testing. The data collected referred to invasive female breast cancer cases diagnosed between 2004 and 2009. The investigation focused on 1) the overexpression and amplification of the human epidermal growth factor receptor 2 oncogene (HER2); 2) the expression of oestrogen (ER) and progesterone (PgR) receptors; and 3) the proliferation index (PI). Weighted percentages, the heterogeneity among and within countries, and the correlation between responses and calendar years were evaluated. The study was based on 19,644 breast cancers. RESULTS: Overall, 85.9% of the cases were tested for HER2, 91.8% for both ER and PgR, and 74.1% for proliferative markers. For HER2 and ER-PgR, the frequency of testing increased from 2004 to 2009. Testing varied among countries (HER2 from 82.0% to 95.9%, ER-PgR from 89.3% to 98.9%, PI from 10% to 92%) and also within the same country (e.g. HER2 in Italy from 51% to 99%) as well as within single cancer registries. The most relevant differences were in the scores for positive/negative/not clearly defined HER2 (e.g. HER2 was defined positive if IHC 3+ in 21/33 registries), and in the cut-off of positive cells for ER/PgR (from >0% to >30%) and PI positivity (from >0% to >20%). CONCLUSIONS: Biological markers are widely tested in the Romance language countries; however, the parameters defining their positivity may vary, raising concerns about homogeneity in breast cancer classification and treatment.

Impact of diabetes on overall and cancer-specific mortality in colorectal cancer patients.

PURPOSE: Diabetes is associated with increased risk of developing colorectal cancer (CRC), but its effect on overall and cancer-specific mortality in CRC patients has been little investigated. The aim of this study was to assess the influence of diabetes on overall and cancer-specific mortality in Italian CRC patients. METHODS: Cases of adult (≥15 years) CRC, diagnosed in 2003-2005, most followed-up to the end of 2008, were randomly selected from the Italian Cancer Registries database. Diabetic status, sex, age, tumor stage, subsite, treatment, morphology, and grade were obtained by consultation of patient clinical records. Poisson multivariable regression models, adjusted for potential confounding variables, were used to estimate hazard ratios (HRs) for all-cause and CRC-specific mortality, according to diabetic status. RESULTS: A total of 1,039 CRC cases with known fasting glucose or diabetic status, archived in 7 cancer registries, was analyzed. Compared to non-diabetics, diabetics (specific diagnosis or glucose ≥126 mg/dl) were older and less likely to receive adjuvant therapy. Diabetics were at higher risk of all-cause death [HR 1.41; 95 % confidence interval (CI) 1.18-1.70] and CRC death (HR 1.36; 95 % CI 1.11-1.67), with no differences by sex or subsite. CONCLUSIONS: Diabetes was significantly associated with increased overall and CRC-specific mortality. Our findings indicate that diabetes is a negative prognostic factor for CRC and suggest that in patients with CRC, diabetes prevention and treatments that stabilize the condition and control its complications might reduce mortality. Further studies are required to ascertain the mechanisms linking diabetes to greater mortality in CRC patients.

Key factors influencing lung cancer survival in northern Italy.

AIM: Lung cancer is a major cause of cancer death worldwide. The aims of this study were to analyze presentation, treatment and survival for lung cancer in northern Italy, and identify factors influencing survival. METHODS: A total of 1180 lung cancer cases diagnosed in four north Italian cancer registries (Biella, Modena, Reggio Emilia, Romagna) in 2003-2005 were analyzed. Information on morphology, stage, diagnostic examinations, chemotherapy, radiotherapy, and surgical treatment was collected from clinical records. Three-year relative survival and relative excess risks of death were estimated. RESULTS: Overall, 10% of cases were stage I, 50% stage IV, and 12% stage unknown. Romagna - where sophisticated diagnostic examinations were performed more often - had proportionately more microscopically verified cases and resected cases than Biella. Romagna had also high proportions of cases given chemotherapy and radiotherapy. Three-year survival was 14%, range 10% (Biella) to 19% (Romagna); 69% for stage I, 3% for stage IV. Stage I survival was higher in Romagna (82%) than Reggio Emilia and Biella (60-61%) but for operated stage I cases, survival was similar (88%) in Romagna and Biella. The fully adjusted model showed a higher risk of death in Biella (1.23, 95%CI 1.02-1.48) than Modena (reference). CONCLUSIONS: Stage and surgery are key factors influencing survival. Centralizing lung cancer treatment to improve diagnostic work-up may improve outcomes.

Survival of European patients diagnosed with myeloid malignancies: a HAEMACARE study.

Population-based information on the survival of patients with myeloid malignancies is rare mainly because some entities were not recognized as malignant until the publication of the third revision of the International Classification of Diseases for Oncology and World Health Organization classification in 2000. In this study we report the survival of patients with myeloid malignancies, classified by updated criteria, in Europe. We analyzed 58,800 cases incident between 1995 to 2002 in 48 population-based cancer registries from 20 European countries, classified into HAEMACARE myeloid malignancy groupings. The period approach was used to estimate 5-year relative survival in 2000-2002. The relative overall survival rate was 37%, but varied significantly between the major groups: being 17% for acute myeloid leukemia, 20% for myelodysplastic/myeloproliferative neoplasms, 31% for myelodysplastic syndromes and 63% for myeloproliferative neoplasms. Survival of patients with individual disease entities ranged from 90% for those with essential thrombocythemia to 4% for those with acute myeloid leukemia with multilineage dysplasia. Regional European variations in survival were conspicuous for myeloproliferative neoplasms, with survival rates being lowest in Eastern Europe. This is the first paper to present large-scale, European survival data for patients with myeloid malignancies using prognosis-based groupings of entities defined by the third revision of the International Classification of Diseases for Oncology/World Health Organization classifications. Poor survival in some parts of Europe, particularly for treatable diseases such as chronic myeloid leukemia, is of concern for hematologists and public health authorities.

Regional inequalities in cancer care persist in Italy and can influence survival.

BACKGROUND: Population-based cancer registry studies of care patterns can help elucidate reasons for the marked geographic variation in cancer survival across Italy. The article provides a snapshot of the care delivered to cancer patients in Italy. METHODS: Random samples of adult patients with skin melanoma, breast, colon and non-small cell lung cancers diagnosed in 2003-2005 were selected from 14 Italian cancer registries. Logistic models estimated odds of receiving standard care (conservative surgery plus radiotherapy for early breast cancer; surgery plus chemotherapy for Dukes C colon cancer; surgery for lung cancer; sentinel node biopsy for >1mm melanoma, vs. other treatment) in each registry compared to the entire sample (reference). RESULTS: Stage at diagnosis for breast, colon and melanoma was earlier in north/central than southern registries. Odds of receiving standard care were lower than reference in Sassari (0.68, 95%CI 0.51-0.90) and Napoli (0.48, 95%CI 0.35-0.67) for breast cancer; did not differ across registries for Dukes C colon cancer; were higher in Romagna (3.77, 95%CI 1.67-8.50) and lower in Biella (0.38, 95%CI 0.18-0.82) for lung cancer; and were higher in Reggio Emilia (2.37, 95%CI 1.12-5.02) and lower in Ragusa (0.27, 95%CI 0.14-0.54) for melanoma. CONCLUSIONS: Notwithstanding limitations due to variations in the availability of clinical information and differences in stage distribution between north/central and southern registries, our study shows that important disparities in cancer care persist across Italy. Thus the public health priority of reducing cancer survival disparities will not be achieved in the immediate future.

Cancer prevalence in Italy: an analysis of geographic variability.

PURPOSE: Statistics on cancer prevalence are scanty. The objectives of this study were to describe the cancer prevalence in Italy and to explore determinants of geographic heterogeneity. METHODS: The study included data from 23 population-based cancer registries, including one-third of the Italian population. Five-year cancer prevalence was observed, and complete prevalence (i.e., all patients living after a cancer diagnosis) was estimated through sex-, age-, cancer site-, and observation period length-specific completeness indices by means of regression models. RESULTS: In 2006, 3.8 % of men and 4.6 % of women in Italy were alive after a cancer diagnosis, with a 5-year prevalence of 1.9 % and 1.7 % in men and women, respectively. A relevant geographic variability emerged for all major cancer sites. When compared to national pooled estimates, crude cancer prevalence proportions were 10 % higher in the north and 30 % lower in the south of Italy. However, these variations were consistently reduced after age adjustment and, in both sexes, largely overlapped those of incidence rates, with correlations >0.90 between variations of prevalence and incidence for all cancer sites and areas. CONCLUSIONS: Magnitude of the cancer prevalence and the geographic heterogeneity herein outlined in Italy will help in meeting the needs of specific population of survivor patients.
