Abstract
BACKGROUND Survival is a key metric of the effectiveness of a health system in managing cancer. We set out to provide a comprehensive examination of worldwide variation and trends in survival from brain tumors in adults, by histology. METHODS We analyzed individual data for adults (15-99 years) diagnosed with a brain tumor (ICD-O-3 topography code C71) during 2000-2014, regardless of tumor behavior. Data underwent a 3-phase quality control as part of CONCORD-3. We estimated net survival for 11 histology groups, using the unbiased nonparametric Pohar Perme estimator. RESULTS The study included 556,237 adults. In 2010-2014, the global range in age-standardized 5-year net survival for the most common sub-types was broad: in the range 20%-38% for diffuse and anaplastic astrocytoma, from 4% to 17% for glioblastoma, and between 32% and 69% for oligodendroglioma. For patients with glioblastoma, the largest gains in survival occurred between 2000-2004 and 2005-2009. These improvements were more noticeable among adults diagnosed aged 40-70 years than among younger adults. CONCLUSIONS To the best of our knowledge, this study provides the largest account to date of global trends in population-based survival for brain tumors by histology in adults. We have highlighted remarkable gains in 5-year survival from glioblastoma since 2005, providing large-scale empirical evidence on the uptake of chemoradiation at population level. Worldwide, survival improvements have been extensive, but some countries still lag behind. Our findings may help clinicians involved in national and international tumor pathway boards to promote initiatives aimed at more extensive implementation of clinical guidelines.

Anaerobic bloodstream infections in Italy (ITANAEROBY): A 5-year retrospective nationwide survey. Anaerobe 2022; 75:102583. [PMID: 35568274 DOI: 10.1016/j.anaerobe.2022.102583] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2021] [Revised: 05/01/2022] [Accepted: 05/04/2022] [Indexed: 12/26/2022]
Abstract
INTRODUCTION A lack of updated data on the burden and profile of anaerobic bloodstream infections (ABIs) exists. We assessed the incidence of ABIs and trends in antimicrobial resistance in anaerobes isolated from blood in Italy. MATERIAL AND METHODS We conducted a retrospective study on 17 Italian hospitals (2016-2020). Anaerobes isolated from blood culture and their in vitro susceptibility profiles (EUCAST-interpreted) were registered and analyzed. RESULTS A total of 1960 ABIs were identified. The mean age of ABIs patients was 68.6 ± 18.5 years, 57.6% were males. The overall incidence rate of ABIs was 1.01 per 10.000 patient-days. Forty-seven% of ABIs occurred in medical wards, 17% in ICUs, 14% in surgical wards, 7% in hemato-oncology, 14% in outpatients. The three most common anti-anaerobic tested drugs were metronidazole (92%), clindamycin (89%) and amoxicillin/clavulanate (83%). The three most common isolated anaerobes were Bacteroides fragilis (n = 529), Cutibacterium acnes (n = 262) and Clostridium perfringens (n = 134). The lowest resistance rate (1.5%) was to carbapenems, whereas the highest rate (51%) was to penicillin. Clindamycin resistance was >20% for Bacteroides spp., Prevotella spp. and Clostridium spp. Metronidazole resistance was 9.2% after excluding C. acnes and Actinomyces spp. Bacteroides spp. showed an increased prevalence of clindamycin resistance through the study period: 19% in 2016, 33% in 2020 (p ≤ 0.001). CONCLUSIONS Our data provide a comprehensive overview of the epidemiology of ABIs in Italy, filling a gap that has existed since 1995. Caution is needed when clindamycin is used as empirical anti-anaerobic drug.

Virulence Determinants in Staphylococcus aureus Clones Causing Osteomyelitis in Italy. Front Microbiol 2022; 13:846167.

Abstract
Staphylococcus aureus is the most common pathogen causing osteomyelitis (OM). The aim of this study was to explore the clonal complex (CC) distribution and the pattern of virulence determinants of S. aureus isolates from OM in Italy. Whole-genome sequencing was performed on 83 S. aureus isolates from OM cases in six hospitals. Antibiotic susceptibility tests showed that 30.1% of the isolates were methicillin-resistant S. aureus (MRSA). The most frequent CCs detected were CC22, CC5, CC8, CC30, and CC15, which represent the most common lineages circulating in Italian hospitals. MRSA were limited in the number of lineages (CC22, CC5, CC8, and CC1). Phylogenetic analysis followed the sequence type-CC groupings and revealed a non-uniform distribution of the isolates from the different hospitals. No significant difference in the mean number of virulence genes carried by MRSA or MSSA isolates was observed. Some virulence genes, namely cna, fib, fnbA, coa, lukD, lukE, sak, and tst, were correlated with the CC. However, different categories of virulence factors, such as adhesins, exoenzymes, and toxins, were frequently detected and unevenly distributed among all lineages. Indeed, each lineage carried a variable combination of virulence genes, likely reflecting functional redundancy, and arguing for the importance of those traits for the pathogenicity in OM. In conclusion, no specific genetic trait in the most frequent lineages could explain their high prevalence among OM isolates. Our findings highlight that CCs detected in OM isolates follow the epidemiology of S. aureus infections in the country. It is conceivable that any of the most common S. aureus CC can cause a variety of infections, including OM.

Abstract
In response to the rapidly evolving of SARS-CoV-2 infection, numerous serological tests have been developed but their sensitivity and specificity are unclear. We collected serum samples of patients and health-care professionals to assess the accuracy of chemiluminescent (CLIA) and two lateral flow immunochromatographic assays (LFIA) to determine IgG and IgM antibodies to SARS-CoV-2 virus. We calculated the φ correlation for qualitative results and test accuracy, adopting the following case definition: either real-time-PCR positivity or serological positivity with at least two different tests. We analyzed 259 samples, obtaining strong correlation between CLIA and both LFIA for IgG (φ=0.9), and moderate correlation for IgM (φ=0.6). For patients, the sensitivity was suboptimal for all methods (CLIA 81%, LFIA A 85%, LFIA B 78%), while it was poor in asymptomatic health-care workers (CLIA 50%, LFIA A 50%, LFIA B 33%). Overall, CLIA is more sensitive and specific for the determination of both IgG and IgM, whilst both LFIA methods reported good sensitivity and specificity for IgG, but scarce sensitivity for the IgM determination. The determination of SARS-CoV-2-specific IgG is useful to detect infection 6 days from symptom onset.

Abstract
AIM To evaluate the impact of multidisciplinary team case discussion including computed tomography (CT) radiologic review on surgical outcome and overall survival (OS) of patients with pancreatic ductal adenocarcinoma (PDAC). METHODS Patients with PDAC evaluated in 2008-2011 and 2013-2016 (before and after multidisciplinary team introduction), aged <85 years and staged I-III, were included. Surgical failures and 2-year OS were compared in these periods. Available CT scans of preintervention period (2008-2011) cases were reviewed by two radiologists in consensus, assigning a resectability judgment to evaluate in how many cases a different recommendation would be achieved. RESULTS A total of 316 patients (49.3% female, age 71±10 years) were included: 132 in 2008-2011 and 184 in 2013-2016. The proportion of patients who underwent upfront surgery was similar in the two periods (51% vs 47% in 2008-2011 vs 2013-2016). Neoadjuvant referral increased from 7% to 21% and surgical resection was excluded for 42% patients in 2008-2011 vs 33% in 2013-2016 (p = 0.002). Adjusting by age, sex, and stage, surgical failures slightly decreased in 2013-2016 (odds ratio 0.89, 95% confidence interval 0.53-1.51); the decrease was stronger when therapeutic choice complied with CT indications (odds ratio 0.76, 95% confidence interval 0.36-1.63); in both cases, the decrease could be due to chance. After correction for age, sex, and stage, the hazard ratio of 2013-2016 for OS was 0.83 (95% confidence interval 0.64-1.09). In 33/114 (29%) patients, CT retrospective review produced a change in resectability judgment. CONCLUSION Although differences could be due to chance or generic improvement, the consistency between process and outcome indicators suggests that multidisciplinary team approach with radiologic review may improve outcomes.

Abstract
Background Group B streptococcus (GBS) is a leading cause of sepsis, pneumonia and meningitis in infants, with long term neurodevelopmental sequelae. GBS may be associated with poor pregnancy outcomes, including spontaneous abortion, stillbirth and preterm birth. Intrapartum antibiotic prophylaxis (IAP) is currently the only way to prevent early-onset disease (presenting at 0 to 6 days of life), although it has no impact on the disease presenting over 6 days of life and its implementation is challenging in resource poor countries. A maternal vaccine against GBS could reduce all GBS manifestations as well as improve pregnancy outcomes, even in low-income countries. Main body The term “PREPARE” designates an international project aimed at developing a maternal vaccination platform to test vaccines against neonatal GBS infections by maternal immunization. It is a non-profit, multi-center, interventional and experimental study (promoted by the St George University of London. [UK]) with the aim of developing a maternal vaccination platform, determining pregnancy outcomes, and defining the extent of GBS infections in children and mothers in Africa. PREPARE also aims to estimate the protective serocorrelates against the main GBS serotypes that cause diseases in Europe and Africa and to conduct two trials on candidate GBS vaccines. PREPARE consists of 6 work packages. In four European countries (Italy, UK, Netherlands, France) the recruitment of cases and controls will start in 2020 and will end in 2022. The Italian PREPARE network includes 41 centers. The Italian network aims to collect: GBS isolates from infants with invasive disease, maternal and neonatal sera (cases); cord sera and GBS strains from colonized mothers whose infants do not develop GBS infection (controls). Short conclusion PREPARE will contribute information on protective serocorrelates against the main GBS serotypes that cause diseases in Europe and Africa. The vaccine that will be tested by the PREPARE study could be an effective strategy to prevent GBS disease.

Abstract
Many studies have reported increasing incidence rates of cutaneous melanoma during the last 30-40 years; the highest have been observed in Australia and New Zealand (27.9/100,000 among males and 25.0 among females) and in North America (10.9/100,000 among males and 7.7 among females). In Italy, from 1994-1998, in the areas covered by cancer registries (23% of Italian population), the incidence rate for males was 8.5 and for females, 1.9/100,000. The aim of the present study was to describe incidence, mortality and survival from cutaneous melanoma in the Umbrian population during the periods 1978-1982 and 1994-1998.

Abstract
OBJECTIVE Resection can potentially cure resectable pancreatic cancer (PaC) and significantly prolong survival in some patients. This large-scale international study aimed to investigate variations in resection for PaC in Europe and USA and determinants for its utilisation. DESIGN Data from six European population-based cancer registries and the US Surveillance, Epidemiology, and End Results Program database during 2003-2016 were analysed. Age-standardised resection rates for overall and stage I-II PaCs were computed. Associations between resection and demographic and clinical parameters were assessed using multivariable logistic regression models. RESULTS A total of 153 698 records were analysed. In population-based registries in 2012-2014, resection rates ranged from 13.2% (Estonia) to 21.2% (Slovenia) overall and from 34.8% (Norway) to 68.7% (Denmark) for stage I-II tumours, with great international variations. During 2003-2014, resection rates only increased in USA, the Netherlands and Denmark. Resection was significantly less frequently performed with more advanced tumour stage (ORs for stage III and IV versus stage I-II tumours: 0.05-0.18 and 0.01-0.06 across countries) and increasing age (ORs for patients 70-79 and ≥80 versus those <60 years: 0.37-0.63 and 0.03-0.16 across countries). Patients with advanced-stage tumours (stage III-IV: 63.8%-81.2%) and at older ages (≥70 years: 52.6%-59.5%) receiving less frequently resection comprised the majority of diagnosed cases. Patient performance status, tumour location and size were also associated with resection application. CONCLUSION Rates of PaC resection remain low in Europe and USA with great international variations. Further studies are warranted to explore reasons for these variations.

Analysis of incidence, mortality and survival for pancreatic and biliary tract cancers across Europe, with assessment of influence of revised European age standardisation on estimates. Cancer Epidemiol 2018; 55:52-60. [PMID: 29777994 DOI: 10.1016/j.canep.2018.04.011] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2018] [Revised: 04/24/2018] [Accepted: 04/25/2018] [Indexed: 12/30/2022]
Abstract
BACKGROUND Pancreatic (PC) and biliary tract (BTC) cancers have higher incidence and mortality in Europe than elsewhere. We analysed time-trends in PC/BTC incidence, mortality, and survival across Europe. Since the European standard population (ESP) was recently revised to better represent European age structure, we also assessed the effect of adopting the revised ESP to age-standardise incidence and mortality data. METHODS We analysed PCs/BTCs (≥15 years) diagnosed in 2000-2007 and followed-up to end of 2008, in 29 European countries across five regions: UK/Ireland, and northern, central, southern, and eastern Europe. Incidence, mortality, and 5-year relative survival were compared between regions, by age, sex, and period of diagnosis. RESULTS Variation in age-standardised incidence (PC 12-15/100,000; BTC 2-6) and mortality (PC 10-14; BTC 1-5) was modest. Eastern Europe had highest incidence and mortality, and lowest survival; northern and southern Europe had highest age-specific incidence (most age groups) for PC and BTC, respectively. Incidence and survival increased slightly from 2000 to 2007, particularly in elderly patients and women, but survival remained poor (≤8% for PC; 13-18% for BTC). Use of the revised ESP for age-standardisation did not impact European regional incidence and mortality rankings. CONCLUSION Poor survival for PC and BTC, together with increasing incidence, indicate that action is required. Countries with higher incidence had higher risk factor frequency, suggesting that prevention initiatives targeting risk factors should be promoted. Improvements in diagnosis and treatment are also required. Our results provide a baseline from which to monitor evolution of the PC/BTC burden in Europe.

Abstract
Data about second primary tumors after prostate carcinoma are controversial. Some authors emphasize an increased incidence of some cancer sites, others an overall diminution. With the aim to provide further information to define the issue, we have analyzed the frequency of second metachronous primary malignancies in patients with diagnosed prostate cancer in the Umbria region of Italy. A total of 410 metachronous cancers among 4528 prostate cancer patients were abstracted from incident cases of the RTUP, over the period 1994–2003. This cohort was compared with all cases (except prostate cancers) recorded in the RTUP archive. The expected number of cases was obtained from indirect standardization with regional incidence rates of several sites. The significance of the observed/expected ratios and the corresponding 95% confidence intervals were based on the Poisson distribution. A significant standardized incidence ratio was found for all sites but prostate, with 410/351 observed/expected cases. The significance disappears considering all sites except prostate and skin non-melanomas. Among several sites, significant standardized incidence ratios were found for skin non-melanomas, for bladder, for rectum, but not for colon cancers. Kidney, ureter and urethra showed a nonsignificant standardized incidence ratio. Nasopharynx showed a significant standardized incidence ratio, but the result was based on a very small number of cases. In our data, the increase in urinary bladder and rectal cancers, after prostate cancer diagnosis, seems to be real: it is plausible that the number of second cancers may be due to increased urologist surveillance, which, in our Region, does not seem to be reduced in elderly men.

Abstract
Aims and background The study aimed to validate model-based incidence estimates by means of observed incidence rates provided by Italian cancer registries, for five major cancer sites (stomach, colon and rectum, lung, breast and prostate cancers) and for all cancers together. Methods Recent incidence rates observed by Italian population-based cancer registries were extracted from the data base of the Italian Association of Cancer Registries. Regional estimates of incidence rates for the same cancers were obtained by the MIAMOD method. Observed and estimated crude incidence rates and incidence trends were compared for the period of diagnosis 1985-2000. Eight Italian cancer registries and seven regions were selected for the analysis since they had incidence data available during the entire selected period. Results and conclusions An excellent agreement between estimated and observed crude incidence rates was found for all single cancer sites, regarding absolute incidence levels and time trends. A partial exception was breast, where empirical data showed a sudden increase in the last three years of observation, perhaps due to organized screenings in some Italian regions, and not captured by statistical models. Substantial underestimation of model-based incidence rates was found for all cancers combined, where the difference tended to increase with calendar year, up to a maximum of 20% in recent years. The greatest part of the discrepancy can be attributed to multiple cancers, which were included in cancer registries statistics but were not accounted for in MIAMOD estimates.

Abstract
e15732 Background: There is currently no standard second-line treatment for metastatic pancreatic adenocarcinoma. The aim of this study is to evaluate the impact of a second-line therapy prior to the introduction of nab-paclitaxel. Methods: From 01/2009 to 12/2014, 204 patients were treated for pancreatic cancer. 166 (81.3%) received first(I)-line chemotherapy. Patients treated in second(II)-line were evaluated in two different periods, before and after FOLFIRINOX introduction. Results: 99 patients (59.6% treated in I line) received II line therapy. The main regimens used in I line were gemcitabine during the period 2009-2011 and FOLFIRINOX from 2012 to 2014 (some patients were treated with nab-paclitaxel/gemcitabine approved before AIFA registration). We observed that the increased use of gemcitabine in the second period was related to a reduction in I line use (52.1% patients after 2012 vs 21.4% before 2012). Considering the different therapeutic regimens employed in I and II line, no statistically significant differences in overall survival were observed over the two periods (Table). The probability of receiving II line chemotherapy did not change in the two groups (HR 0.6; p=0.2). Conclusions: Within the limits of a retrospective analysis, all II line regimens used showed the same effectiveness, regardless of I line treatment employed. It is likely that the large number of patients treated with effective therapies in II line have concealed the impact of front-line schemes. In an ongoing study we are evaluating the impact of introducing nab-paclitaxel in clinical practice. [Table: see text]

Abstract
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.

Ki-67 cytological index can distinguish well-differentiated from poorly differentiated pancreatic neuroendocrine tumors: a comparative cytohistological study of 53 cases. Virchows Arch 2014; 465:49-55. [PMID: 24807732 DOI: 10.1007/s00428-014-1585-7] [Citation(s) in RCA: 25] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2013] [Revised: 04/09/2014] [Accepted: 04/24/2014] [Indexed: 12/30/2022]
Abstract
The Ki-67 labeling index has been found to bear prognostic significance in gastrointestinal neuroendocrine tumors (NETs), and it was recently incorporated in NET histological grading. Nevertheless, a reliable preoperative determination of NET grading could be useful in clinical practice. The aim of this study is to compare the results of Ki-67 labeling index, as measured on cytological samples and on surgical specimens of patients with pancreatic NETs (P-NETs). We also investigated whether concordance might be improved, using a 5 % (instead of 2 %) cutoff value for defining G2 tumors. We retrospectively identified 48 consecutive patients with 53 P-NETs, from our five institutions, and we measured Ki-67 labeling index on their cytological samples and surgical specimens. The traditional 2 % and the alternative 5 % cutoff values were used to classify G2 tumors. The concordance rate between cytological and histological grading was 46/53 (86.8 %; weighted κ statistic 0.77; 95 % confidence interval (95 % CI) 0.60-0.94). No cases of cytological G1-G2 NETs were upgraded to G3 neuroendocrine carcinoma (NEC) at histological grading. Cytology was found to be highly specific in the diagnosis of both G2 (94.1 %; 95 % CI 80.3-99.3) and G3 tumors (100.0 %; 95 % CI 92.8-100), but the sensitivity was poor for G2 NETs (66.7 %; 95 % CI 38.4-88.2) and high for the prediction of G3 NECs (100 %; 95 % CI 39.8-100.0). When the 5 % cutoff value was adopted, concordance rate was 49/53 (92.4 %; weighted κ 0.82; 95 % CI 0.64-1.00). In conclusion, Ki-67 cytological expression can distinguish well-differentiated (both G1 and G2) from poorly differentiated P-NETs, and it may be useful for their preoperative classification.

Recent trends in incidence, mortality and survival after cancer of the female breast and reproductive organs. Umbria, Italy: 1978-2005. EUR J GYNAECOL ONCOL 2010; 31:174-180.

Abstract
This study analyzed the incidence, mortality and survival after cancer of the female breast and reproductive organs in the Umbria region of Italy with the aim of generating hypotheses to explain trends. Mortality data were supplied by ISTAT (1978-1993) and ReNCaM (1994-2005) and incidence (1994-2005) and survival (at 12/31/2007) data by RTUP. Joinpoint regression was applied to evaluate temporal trends of the age-adjusted incidence and mortality rates. Mortality, incidence and relative survival rates were compared with national and international data. The incidence of breast cancer increased up to 2001 and afterwards significantly decreased; mortality rates significantly decreased after 1994. Uterine corpus incidence was practically stable, and decreased over the study period; mortality from all uterine subsites significantly decreased from 1978 onwards. Trends in ovarian cancer incidence and mortality (after 1985) were constant. Trends in occurrence of breast and cervical cancer were linked to population screening of Umbrian women, noting a low compliance by younger females with cervical cancer screening and emphasizing the opportunity of starting breast cancer screening at a younger age. Trends in the incidence of cancer of the uterus and ovary, though unsteady, were probably related to modifications in risk factor exposure. Survival was better for breast and cervical cancers than in the 1978-1982 period and might be due to early diagnosis and progress in therapy.

Abstract
Using data from the Umbrian Population Cancer Registry (RTUP) we tested the hypothesis of relationships between several subsequent cancer sites in women who had had breast cancer. New patients (7,840) were collected from the RTUP between 01/01/1994 and 31/12/2006; 24 DCO cases were excluded; 332 successive multiple cancers in 320 patients were recorded. Including all second cancers, metachronous contralateral breast cancer, the observed/expected ratio (SIR) was non-significant. Excluding these cases, SIR was significantly lower whether with or without second skin carcinomas. SIR of all second metachronous contralateral cancers, excluding skin carcinomas, was non-significant. Significantly lower risk involved the colorectum, stomach, pancreas and metachronous breast with different histology. A significant excess was found of melanoma and total second breast cancers, including the contralateral. The excessive skin melanoma in breast cancer survivors was attributed to the relationship with BRCA2 and CDKN2A mutation-positive patients. The excess risk due to the CDKN2A mutation should also include pancreatic cancer which, in the present study, presented a significantly lower risk.

Abstract
BACKGROUND Spatial clustering of different diseases has received much less attention than single disease mapping. Besides chance or artifact, clustering of different cancers in a given area may depend on exposure to a shared risk factor or to multiple correlated factors (e.g. cigarette smoking and obesity in a deprived area). Models developed so far to investigate co-occurrence of diseases are not well-suited for analyzing many cancers simultaneously. In this paper we propose a simple two-step exploratory method for screening clusters of different cancers in a population. METHODS Cancer incidence data were derived from the regional cancer registry of Umbria, Italy. A cluster analysis was performed on smoothed and non-smoothed standardized incidence ratios (SIRs) of the 13 most frequent cancers in males. The Besag, York and Mollie model (BYM) and Poisson kriging were used to produce smoothed SIRs. RESULTS Cluster analysis on non-smoothed SIRs was poorly informative in terms of clustering of different cancers, as only larynx and oral cavity were grouped, and of characteristic patterns of cancer incidence in specific geographical areas. On the other hand BYM and Poisson kriging gave similar results, showing cancers of the oral cavity, larynx, esophagus, stomach and liver formed a main cluster. Lung and urinary bladder cancers clustered together but not with the cancers mentioned above. Both methods, particularly the BYM model, identified distinct geographic clusters of adjacent areas. CONCLUSION As in single disease mapping, non-smoothed SIRs do not provide reliable estimates of cancer risks because of small area variability. The BYM model produces smooth risk surfaces which, when entered into a cluster analysis, identify well-defined geographical clusters of adjacent areas. It probably enhances or amplifies the signal arising from exposure of more areas (statistical units) to shared risk factors that are associated with different cancers. In Umbria the main clusters were characterized by high risks for cancers with alcohol and tobacco both as risk factors. Tobacco-only related cancers formed a separate cluster to the alcohol- and tobacco-related sites. Joint spatial analysis or investigation of hypothesized exposures might be used for further investigation into interesting geographical clusters.

Incidence of primary liver cancer in Italy between 1988 and 2002: an age-period-cohort analysis. Eur J Cancer 2007; 44:285-92.

Abstract
We conducted in Italy a study to evaluate trends of primary liver cancer (PLC) and to disentangle the period from birth-cohort effects on PLC incidence. Cases aged<80 years and diagnosed between 1988 and 2002 in 20 areas covered by population-based Cancer Registries were included. Age-standardised incidence rates and age-period-cohort effects were estimated. In 1998-2002, incidence rates of PLC were 21.1/100,000 men and 6.0/100,000 women. In both genders, incidence rates increased slightly between 1988-1992 and 1993-1997 but did not rise thereafter. Amongst men, PLC risk increased in every cohort born after 1913 and the rise became steeper for cohorts born in 1948. In women, an upward trend appeared only in the cohorts born after 1953. Incidence of PLC over the last two decades in Italy did not substantially change but huge geographical variability emerged, mainly due to different times and modalities of spread of hepatitis C virus.

Abstract
The aim of this study was to examine differences in avoidable mortality between males and females in the Umbria region (Italy). Data on deaths was obtained from the Regional mortality registry (RENCAM). Deaths which occurred in the years from 1994 to 2004 were classified into three groups, according to the type of intervention through which they may have been avoided: primary prevention, early detection and treatment or improved medical care. All causes of death were coded according to the IX and X revisions of the International Classification of Causes of Death.

Abstract
The aim of this study was to determine the incidence of multiple bladder-prostate cancers in the population of the Italian region of Umbria and to clarify some diagnostic aspects. Prostate and bladder cancer incidence data in Umbria were obtained from cancer registry records. In the period from 1994 to 2004, 3,470 new patients with bladder cancer and 5,430 new patients with prostate cancer were registered. Among these patients there were 238 who presented multiple bladder and prostate cancers. Synchronous cancers were detected in 74 of these patients. Fifty-four of them had simultaneous tumors (diagnosed during the same hospitalization), while in 16 patients bladder cancer was detected earlier than prostate cancer and in 4 patients the opposite occurred. This study confirmed an increase in prostate cancer diagnoses in patients with bladder cancer. The increase was mainly accounted for by the detection of prostate cancers during cystectomies performed for bladder carcinoma.

Abstract
BACKGROUND The aim of the present paper was to analyse cancer mortality in the Umbria region, from 1978 to 2004. Mortality trends depend on a number of factors including exposures, health system interventions, and possibly artefact (e.g. classification change, variations of data completeness). Descriptive data on mortality only allow for generation of hypotheses to explain observed trends. Some clues on the respective role of possible mortality determinants may be found comparing mortality with incidence and survival data. METHODS Mortality data for the periods 1978-1993 and 1994-2004 were supplied by the National Institute of Statistics (ISTAT) and the Regional Causes of Death Registry (ReNCaM) respectively. Sex and site-specific mortality time trends were analysed by the "joinpoint regression" method. RESULTS For all sites combined, in both sexes, the standardised rate was first increasing before the end of the eighties and decreasing thereafter. Gastric cancer mortality showed a different trend by gender; that is the rate constantly decreased over the period among females while, for males, it was first increasing up to 1985 and decreasing thereafter. Liver cancer trend showed a pattern similar to gastric cancer. Large bowel cancer showed a gender specific trend, that is it was increasing among males and stable among females. Also lung cancer mortality varied by gender: it started to decline after 1989 among males but was steadily increasing over the study period among women. A decreasing trend for female breast cancer mortality began in 1994. Prostate cancer mortality trend is the only one showing two significant joinpoints: mortality decreased up to 1990, then it increased up to 1998 and, finally, was decreasing. CONCLUSION Overall cancer mortality was decreasing in both sexes in Umbria and this favourable trend will probably continue and further improve since population screening against breast, cervix, and large bowel cancers were recently introduced. Besides gastric cancer, tobacco-related cancers and prostate cancer mainly contributed to mortality reduction in males, whereas breast cancer mainly contributed to declining mortality in females.

Abstract
Differences in gynaecological cancer incidence and mortality in the urban and rural areas of the Umbria region (central Italy) were investigated. All women with primary invasive breast cancers, uterine cervix and uterine corpus, and ovarian cancers diagnosed during the periods 1978-1982 and 1998-2002 were identified and analysed according to place of residence (either urban or rural). Mortality data were supplied by the National Institute of Statistics (ISTAT) for the period 1978 to 1982, whereas for the 1994-2002 period they were supplied by the Regional Nominative Causes of Death Registry (ReNCaM). Incident cases considered were taken from an ad hoc survey for the first period and from the Umbrian Population Cancer Registry database for the second one. For each site the age-adjusted incidence (AAIR) and mortality (AADR) rates were calculated. The expected number of rural cases was obtained from indirect standardisation with urban incidence and mortality rates of several sites. The significance of the observed expected ratios (SIRs for incidence and SMRs for mortality) and the corresponding 95% confidence intervals were based on the Poisson distribution. Urbanisation levels were established following the classification of the Italian Institute of Statistics. For all sites, excluding the ovary during the most recent period, the SIR relative to rural areas was below 1, but the rates were statistically significant only for breast cancer in both periods (SIR 0.81, 95% CI 0.74-0.88 and SIR 0.82, 95% CI 0.77-0.88, respectively) and for cervix uteri in the first period (SIR 0.77, 95% CI 0.59-0.94). The lower breast cancer incidence in the rural area could also be due to lesser compliance with screening procedures which, up until 2002, were not provided in the form of mass-screenings throughout the region by the Regional Health Department. These results underscore the need for continued efforts to provide preventive health services to medically underserved women throughout Umbria, including rural communities. Underutilisation of preventive healthcare services may result in failure to identify healthcare problems that might be successfully managed with medication or lifestyle changes, as well as missed opportunities to prevent potentially life-threatening diseases.

Abstract
Using incidence, survival and mortality we tried to verify the effectiveness of mass-screening interventions for cervical uterine, breast, and colorectal cancer in females. Mortality data concern the period from 1978-2002. Incident cases derived from an ad hoc survey for 1978-1982 data and from the RTUP from 01/01/1994 to 31/12/2002. Relative survival rates were calculated for 1978-1982, 1994-1997 and 1998-2002 time intervals. All standardized mortality figures showed a steady trend. Incidence rates concerning cervical uterine cancer showed a decrease starting from the 1978-1982 period, whereas those for breast cancer had a constant increasing trend, and those for colorectal cancer increased up to 1997-1999 and later remained constant. For breast cancer the 5-year survival rate increased about 15% compared to the first period, for colon cancer there was less of an increase and the increase for cervical uterine cancer survival was only for the 1998-2002 period compared to the former ones. With constant incidence rates, improvement in survival from cervical uterine cancer may be due to a high number of cancer cases detected at an early stage. The effect of breast cancer screening on incidence is evident, though differences still did not influence mortality and survival. Colorectal cancer epidemiology can be considered as a prescreening pattern. Mortality, incidence and survival data allow a good overview for the effectiveness of screening procedures.

Abstract
Aims and background The epidemiology of colorectal cancer in Umbria, Italy, was evaluated, and data were analyzed in the pre-screening period to better understand the etiology of the disease and to develop screening strategies. Materials and methods Incident data were collected by the Umbrian Population Cancer Registry and mortality data by the Nominative Regional Mortality Registry from 1994 to 2002. The survival rates relative to Italian cancer registries were derived from the Italian Associations of Cancer Registries publications. Time trends were analyzed by joinpoint regression. The follow-up for survival rates referred to December 31, 2005. Results The trend of colorectal cancer age-adjusted incidence showed a slight, constant, but non significant increase over time. The mortality trend showed a slight, constant, but non-significant decrease. Age at diagnosis remained constant in males, whereas in females it showed a significant increase of about 1.5 years. In the last period, all incidence rates increased with age, but in males they presented a rapid increase in the 55-74 age group, levelled and declined up to 84 and after again reached, which could be a consequence of opportunistic screening practice, probably undergone by males. Mortality in both sexes increased with age, whereas survival rates fell. Comparison of survival rates in some Italian cancer registries showed that the Umbria region, in the 1994-1996 period, was the zone with the highest relative survival; in the 1996-1999 period, the rate stopped, differently from other Italian zones. In the last period, the highest survival rates were recorded by registries covering zones with active screening programs. Conclusions The present reduction of mortality in Umbria, as in other Italian areas, is dependent on the natural behavior of the disease, which is linked to a birth cohort-related effect of stabilization and decrease in exposure to risk factors.

Abstract
In order to obtain information regarding the efficacy of healthcare services in the region of Umbria (Italy), trends in mortality due to the main causes of death in this region, between 1994-2004, were analysed. Mortality data was collected from the Nominal Registry of Causes of Death. Standardized mortality and years of potential life lost (YPLL) rates, and cumulative death risk were used as indicators. Joinpoint regression was used to determine whether temporal changes in indicator trends were statistically significant. The joinpoint analysis of mortality trends has shown that general mortality, as well as specific mortality due to malignant tumors, cardiovascular disease, gastrointestinal disease and accidental causes declined over the examined time period. Statistically significant decreases in the indicators used were constant over time: in fact, joinpoints were found only for YPLL and cumulative risk trends for cardiovascular disease-related mortality. These results have provided important information regarding healthcare in the Umbria region.

Abstract
In Umbria, region of Central Italy, lung cancer is the leading cause of death due to cancer in males. The aim of this work is to highlight decrease of mortality from lung cancer in males in Umbria, in the last 20 years and to describe relationship among incidence, mortality and survival of this cancer. The incidence data derived from an ad hoc survey carried out over the period 1978-1982 and for 1994-1999 from the Umbrian Population Cancer Registry (RTUP). The mortality data were derived from official publications of the Italian Central Institute for Statistics (ISTAT) and covered the entire period 1978-1999. Estimated annual percent change (EAPC) was calculated by joinpoint regression analysis. Decrease of mortality from male lung cancer in Umbria began in the 1990-ies due to reduced quantity of tar in cigarettes, decreasing consumption of tobacco and increasing of survival derived from the quality and the effectiveness of the oncological health care system.

Abstract
The aim of this study is to analyze the upper aerodigestive cancer survival in Umbria, a central Italian region, in the periods 1978-82 and 1994-98. The cases' data diagnosed in the period 1978-82 were derived from an ad hoc survey carried out in Umbria and for the years 1994-98 from Umbria Population-based Registry (RTUP). In the period 1994-98 the relative survival has lightly improved compared with the previous one. Comparison among five year relative standardized survival for head and neck, oesophagus and larynx, in Umbria region and in the other Italian registries, shows a quite high survival that could be further improved with an early diagnosis and, consequently, less destroying treatments.

Abstract
The aim of the study is to show the colorectal cancer trend in Umbria, a central Italian region, from 1978 to 1999. Data concerning regional incidence, mortality and survival derived from an ad hoc survey carried out in Umbria in the period 1978-1982 and from Umbria Population-based Registry (RTUP) for the years 1994-1999. The incidence of colorectal cancer increases in both sexes, expecially for the age class > 75 years. Mortality rises slightly, without no difference between sexes. Survival of patients with colorectal cancer has improved in the two sexes from 45 to 74 years-age, while the lower survival has registered for age between 75 and 84 years. We concluded that the situation in Umbria is quiet good, but it is affected by aging of Umbrian population. Delaying in diagnosis or inefficacy in therapy can explain shorter survival in older patients.
