Aims and background. In Veneto a regional cancer registry has been operating since 1987 which provides incidence and survival data for the region. It currently covers 48% of the regional population. The aim of this paper is to provide estimates of the incidence, mortality and prevalence of the major cancers for the whole Veneto region in the period 1970-2015. 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. Survival was modeled on the basis of published data from the Italian cancer registries. Results. In 2012 the most frequent cancer sites were colon-rectum, prostate and breast with 4,677, 3,760 and 3,729 new diagnosed cases, respectively. The incidence rates were estimated to increase constantly for female lung cancer, prostate cancer, colorectal cancer and melanoma, while they were decreasing for cervical cancer and stomach cancer. For male lung cancer and female breast cancer the rates increased, reaching a peak, and then decreased. In the last years of the period of analysis, mortality declined for all cancers: the highest number of deaths (2,390 in both sexes) was estimated for lung cancer in 2012. Prevalence was increasing for all the considered cancer sites with the exception of lung cancer in men, for which the prevalence was estimated to increase until 2007 and then stabilize. By contrast, the cervical cancer decreased during the whole period. In 2012 breast cancer had the highest prevalence, with about 52,000 cases. Conclusion. This paper provides a description of the burden of the major cancers in Veneto until 2015. The estimates highlight the continuing reduction of cancer mortality. This decline can be related to the improvement of clinical treatments and to multidisciplinary treatment approaches. In order for this positive trend to continue, implementation and reinforcement of the screening programs is needed, especially for breast and colorectal cancer. Source

Background:The objectives of this study were to quantitatively assess the geographic heterogeneity of cancer prevalence in selected Western Countries and to explore the associations between its determinants.Methods:For 20 cancer sites, 5-year cancer prevalence, incidence, and survival were observed and age standardised for the mid 2000s in the United States, Nordic European Countries, Italy, Australia, and France.Results:In Italy, 5-year crude prevalence for all cancers was 1.9% in men and 1.7% in women, while it was ∼1.5% in all other countries and sexes. After adjustment for the different age distribution of the populations, cancer prevalence in the United States was higher (20% in men and 10% in women) than elsewhere. For all cancers combined, the geographic heterogeneities were limited, though relevant for specific cancers (e.g., prostate, showing >30% higher prevalence in the United States, or lung, showing >50% higher prevalence in USA women than in other countries). For all countries, the correlations between differences of prevalence and differences of incidence were >0.9, while prevalence and survival were less consistently correlated.Conclusion:Geographic differences and magnitude of crude cancer prevalence were more strongly associated with incidence rates, influenced by population ageing, than with survival rates. These estimates will be helpful in allocating appropriate resources. © 2013 Cancer Research UK. All rights reserved. Source

Objectives: To assess variation in the main colonoscopy quality indicators in organised colorectal cancer (CRC) screening programmes based on faecal immunochemical test (FIT). Design: Data from a case-series of colonoscopies of FIT-positive subjects were provided by 44 Italian CRC screening programmes. Data on screening history, endoscopic procedure and histology results, and additional information on the endoscopy centre and the endoscopists were collected. The adenoma detection rate (ADR) and caecal intubation rate (CIR) were assessed for the whole population and the individual endoscopists. To explore variation in the quality indicators, multilevel analyses were performed according to patient/centre/endoscopist characteristics. Results: We analysed 75 569 (mean age: 61.3 years; men: 57%) colonoscopies for positive FIT performed by 479 endoscopists in 79 centres. ADR ranged from 13.5% to 75% among endoscopists (mean: 44.8%). ADR was associated with gastroenterology specialty (OR: 0.87 for others, 95% CI 0.76 to 0.96) and, at the endoscopy centre level, with the routine use of sedation (OR: 0.80 if occasional (<33%); 95% CI 0.64 to 1.00) and availability of screening-dedicated sessions (OR: 1.35; 95% CI 1.11 to 1.66). CIR ranged between 58.8% and 100% (mean: 93.1%). Independent predictors of CIR at the endoscopist level were the yearly number of screening colonoscopies performed (OR: 1.51 for endoscopists with >600 colonoscopies; 95% CI 1.11 to 2.04) and, at the endoscopy centre level, screeningdedicated sessions (OR: 2.18; 95% CI 1.24 to 3.83) and higher rates of sedation (OR: 0.47 if occasional; 95% CI 0.24 to 0.92). Conclusions: The quality of colonoscopy was affected by patient-related, endoscopist-related and centre-related characteristics. Policies addressing organisational issues should improve the quality of colonoscopy in our programme and similar programmes. Source

We present the main results from the fifth survey of the Italian screening programmes for colorectal cancer carried out by the National Centre for Screening Monitoring (Osservatorio Nazionale Screening, ONS) on behalf of the Ministry of Health. By the end of 2008, 87 programmes were active (14 had been activated during the year), and 52,9%of Italians aged 50- 69 years were residing in areas covered by organised screening programmes (theoretical extension). Ten Regions had their whole population covered. In the South of Italy and Islands, 12 new programmes were activated in 2008, including those of Abruzzo and Molise Regions, with an increase of theoretical extension from 7% to 21%. The majority of programmes employ the faecal occult blood test (FOBT), while some have adopted flexible sigmoidoscopy (FS) once in a lifetime, or a combination of both. Overall, about 2,593,000 subjects were invited to undergo FOBT, 71%of those to be invited within the year. The adjusted attendance rate was 47.5% and approximately 1,171,000 subjects were screened. Large differences in the attendance rate were observed among Regions, with 10% of programmes reporting values lower than 30%. Positivity rate of FOBT programmes was 5.9% at first screening (range 2.0-11%) and 4% at repeat screening (range 2.9-6.5%). The average attendance rate for total colonoscopy (TC) was 81.3% and in three Regions it was lower than 70%. Completion rate of TC was 92.2%. Among the 665,264 subjects attending screening for the first time, the detection rate (DR) per 1,000 screened subjects was 2.7 for invasive cancer and 13.1 for advanced adenomas (AA, adenomas with a diameter ≥1 cm, with villous/ tubulo-villous type or with high-grade dysplasia). As expected, the corresponding figures in the 552,391 subjects at repeat screening were lower (1.3‰ and 8.3‰ for invasive cancer and AA, respectively). The DR of cancer and adenomas increased with age and was higher among males. Many programmes reported some difficulties in guaranteeing TC in the appropriate time frame to FOBT+ subjects: in 16.0% of cases the waiting time was longer than two months. Seven programmes employed FS as the screening test: 58.8% of the target population (about 50,000 subjects) were invited and 8,135 subjects were screened, with an attendance rate of 27.2%. Overall, 83% of FS were classified as complete. Overall TC referral rate was 13.5% and the DR per 1,000 screened subjects was 4.7 and 47.5 for invasive cancer and AA, respectively. Source

We present the main results of the sixth survey of the Italian screening programmes for colorectal cancer carried out by the National centre for screening monitoring (Osservatorio nazionale screening, ONS) on behalf of the Ministry of health. By the end of 2009, 98 programmes were active, of which 13 had been activated during the year, and 59% of Italians aged 50-69 years were residing in areas covered by organised screening programmes (theoretical extension). Eleven regions had their whole population covered. In the South of Italy and Islands, 4 new programmes were activated in 2009, with a theoretical extension of 22%. The majority of programmes employ the faecal occult blood test (FOBT), while some have adopted flexible sigmoidoscopy (FS) once in a lifetime and FOBT for non-responders to FS. Overall, about 2,935,000 subjects were invited to undergo FOBT, 40% of those to be invited within the year. The adjusted attendance rate was 50% and approximately 1,426,000 subjects were screened. Large differences in the attendance rate were observed among regions, with 10% of programmes reporting values lower than 29%. Positivity rate of FOBT programmes was 5.6% at first screening (range: 2.5-12.4%) and 4.2% at repeat screening (range: 2.5-7.3%). The average attendance rate to total colonoscopy (TC) was 82.5%and in one region it was lower than 70%. Completion rate for total colonoscopy (TC) was 91.2%. Among the 631,460 subjects attending screening for the first time, the detection rate (DR) per 1,000 screened subjects was 2.4 for invasive cancer and 11.6 for advanced adenomas (AA - adenomas with a diameter ≥ 1 cm, with villous/tubulo-villous type or with high-grade dysplasia). As expected, the corresponding figures in the 824,562 subjects at repeat screening were lower (1.3‰ and 7.6‰ for invasive cancer and AA, respectively). The DR of cancer and adenomas increased with age and was higher among males. Many programmes reported some difficulties in guaranteeing TC in the appropriate time frame to FOBT+ subjects: in 16% of cases the waiting time was longer than two months. Nine programmes employed FS as the screening test: 65% of the target population (about 60,000 subjects) were invited and 9 511 subjects were screened, with an attendance rate of 24.3%. Overall, 81% of FS were classified as complete. Overall TC referral rate was 11% and the DR per 1,000 screened subjects was 2.6 and 43.7 for invasive cancer and AA, respectively. Source
