The aim of the study: This article presents the incidence of prostate cancer, isolated high grade prostatic intraepithelial neoplasia (PIN) and atypical lesions suspicious for prostate cancer (LSPC) during subsequent screening rounds in the centres of five of the countries participating in the European Randomized Study of Screening for Prostate Cancer (ERSPC). The incidence and predictive value of high grade PIN and LSPC for prostate cancer in subsequent biopsy following these diagnoses were evaluated. Patients and methods: Study group consisted of 56,653 screened men in the ERSPC centres of Finland, Italy, Netherlands, Sweden and Switzerland, who underwent 3-7 screening rounds at 2-4 year interval. Data for prostate cancer were obtained from the ERSPC central database. Data for high grade PIN and LSPC were gathered from each ERSPC centre. Detection rates of subsequent prostate cancer in the first re-biopsy after these diagnoses were determined. Results: The average cancer detection rate was 3.5%, 3.2% and 3.5% for the completed rounds 1, 2 and 3, respectively, in all five centres. Incidence of high grade PIN increased from 1.5% in the first round to 5.0% in the third round, varying among centres in the first round between 0.8% and 7.6%. The cancer detection rate in the first re-biopsy after the diagnosis of high grade PIN was 12.9%. Incidence of LSPC was 2.4%, 2.7%, 2.2% and 2.6% in the first, second, third and fourth round, respectively. The cancer detection rate at the first re-biopsy after the diagnosis of LSPC was in average 33.8%. Conclusions: Cancer detection rate was stable during the three screening rounds. The wide variation in frequency in particular of high grade PIN among the ERSPC centres suggests a considerable inter-observer variation. The average comparatively low detection rate of isolated high grade PIN in the first screening round may be screening-related, while its consistent increase during three screening rounds could be the consequence of a.o. previous screening and ageing of the population. The observed low risk of prostate cancer after isolated high grade PIN in this screening setting is in line with the current recommendation to abstain from early repeat biopsies after this diagnosis. The association of LSPC with high incidence of prostate cancer in re-biopsies confirms the need for early repeat biopsies and follow-up of these men. The low percentage of LSPC (<3% of biopsies) throughout all rounds is reassuring as it limits the biopsy burden in a screening setting. © 2010 Elsevier Ltd. All rights reserved. Source

Background: Some recent studies have suggested that laparoscopic surgery for colorectal cancer may provide a potential survival advantage when compared with open surgery. This study aimed to compare cancer-related survivals of patients who underwent laparoscopic or open resection of colon cancer in the same, high volume tertiary center. Methods: Patients who had undergone elective open or laparoscopic surgery for colon cancer between January 2002 and December 2010 were analyzed. A clinical database was prospectively compiled. Survival analysis was calculated by using the Kaplan-Meier method. Results: A total of 460 resections were performed. There were no significant differences between the laparoscopic (n∈=∈227) and the open group (n∈=∈233) apart from tumor stage: stage I tumors were more frequent in the laparoscopic group whereas stage II tumors were more frequent in the open group. The mean number of harvested lymph nodes was significantly higher in the laparoscopic than in the open group (20.0∈±∈0.7 vs 14.2∈±∈0.5, P∈<∈0.01). The 5-year cancer-related survival for patients undergoing laparoscopic resection was significantly higher than that following open resections (83.1% vs 68.5%, P∈=∈0.01). By performing a stage-to-stage comparison, we found that the improvement in survival in the laparoscopic group occurred mainly in patients with stage II tumors. Conclusions: Our study shows a survival advantage for patients who had undergone laparoscopic surgery for stage II colon cancer. This may be correlated with a higher number of harvested lymph nodes and thus a better stage stratification of these patients. © 2015 Cianchi et al.; licensee BioMed Central. Source

The III Italian Consensus Conference on Pleural Mesothelioma (MM) convened on January 29th 2015. This report presents the conclusions of the 'Epidemiology, Public Health and Occupational Medicine' section. MM incidence in 2011 in Italy was 3.64 per 100,000 person/years in men and 1.32 in women. Incidence trends are starting to level off. Ten percent of cases are due to non-occupational exposure. Incidence among women is very high in Italy, because of both non-occupational and occupational exposure. The removal of asbestos in place is proceeding slowly, with remaining exposure. Recent literature confirms the causal role of chrysotile. Fibrous fluoro-edenite was classified as carcinogenic by IARC (Group 1) on the basis of MM data. A specific type (MWCNT-7) of Carbon Nanotubes was classified 2B. For pleural MM, after about 45 years since first exposure, the incidence trend slowed down; with more studies needed. Cumulative exposure is a proxy of the relevant exposure, but does not allow to distinguish if duration or intensity may possibly play a prominent role, neither to evaluate the temporal sequence of exposures. Studies showed that duration and intensity are independent determinants of MM. Blood related MM are less than 2.5%. The role of BAP1 germline mutations is limited to the BAP1 cancer syndrome, but negligible for sporadic cases. Correct MM diagnosis is baseline; guidelines agree on the importance of the tumor gross appearance and of the hematoxylin-eosin-based histology. Immunohistochemical markers contribute to diagnostic confirmation: the selection depends on morphology, location, and differential diagnosis. The WG suggested that 1) General Cancer Registries and ReNaM Regional Operational Centres (COR) interact and systematically compare MM cases; 2) ReNaM should report results presenting the diagnostic certainty codes and the diagnostic basis, separately; 3) General Cancer Registries and COR should interact with pathologists to assure the up-To-date methodology; 4) Necroscopy should be practiced for validation. Expert referral centres could contribute to the definition of uncertain cases. Health surveillance should aim to all asbestos effects. No diagnostic test is recommended for MM screening. Health surveillance should provide information on risks, medical perspective, and smoking cessation. The economic burden associated to MM was estimated in 250,000 Euro per case. Source

Background: Screening for prostate cancer (PC) with prostate-specific antigen (PSA) has been shown to decrease mortality, but has adverse effects, such as false-positive (FP) screening results. We describe the frequency of FP results and assess their relation to subsequent screening attendance, test results and prostate cancer risk in a large randomized trial. Materials and methods: We included data from five centres of the European Randomized Study of Screening for Prostate Cancer, altogether over 61,000 screened men. Men were screened with PSA test at a 2-7 year interval depending on the centre; PSA cut-off was 3.0-4.0 ng/ml. A positive screen with no histologically confirmed PC in biopsy within 1 year was defined as an FP result. Results: Of the 61,604 men who were screened at least once, 17.8% had one or more FP result(s). Almost 20% of men who participated at all screening rounds had one or more FP result(s). More than half of the men with an FP result had another FP if screened again. Men with FP results had a fourfold risk of PC at subsequent screen (depending on the round, 10.0% versus 2.6-2.7% of men with negative screen, risk ratio 3.8-3.9). The PCs following an FP result were in 92.8% of cases localised and low-grade versus 90.4% following a screen-negative result. Conclusions: Our results show that FP results are common adverse effects in PC screening, as they affect at least one in six screened men. False-positive men are more prone to be diagnosed with PC but are also likely to have consistently high PSA levels. © 2011 Elsevier Ltd. All rights reserved. Source

The purpose of this paper is to identify immunologic hallmarks of excessive bodyweight. The analysis is based on 176 adults (106 women, 70 men) who participated in a nested case-control study in Italy. All participants were healthy at the time of blood collection and aged between 36 and 75 years. We employed multivariate analysis of variance and a nonparametric Bayesian additive regression tree approach along with a receiver operating characteristic (ROC) curve analysis to determine the immunologic signature of excessive body weight (i.e., obesity and overweight). Interleukin 8 (IL-8), IL-10, interferon γÎ, and inducible protein 10 were shown to be predictive of excessive body weight with an area under the ROC curve of 71% (p<0.0002). We propose that by using this profile-based approach to define immunologic signatures, it might be possible to identify unique immunologic hallmarks of specific types of obesity. © 2011 Informa UK, Ltd.
