Young immigrant women and cervical cancer screening: participation and lesions detected at the first screening round.

OBJECTIVES: to evaluate if the country of origin affects participation and outcomes of cervical cancer screening. DESIGN: retrospective cohort study. SETTING AND PARTICIPANTS: all Italian and foreign women resident in the Veneto region (North-Eastern Italy) who were born between 1986 and 1992 and who had been invited for the first time through the screening programme between 2011 and 2017 were identified and included in the survey. MAIN OUTCOME MEASURES: participation to screening was calculated along with the detection of Cervical Intraepithelial Neoplasia (CIN) grade 2 or 3 and of carcinoma, by citizenship. RESULTS: 96,105 (77.5%) Italians and 27,958 (22.5%) foreign women were included. Overall, the adjusted participation was 53.3%, with large differences among the geographical study areas. The value was highest for Italian women (56.4%), while women with other citizenships showed lower attendance: 45.5% for Eastern Europe, 44.8% for Sub Saharan Africa, 40.0% for Northern Africa, 38.5% for Central and Southern America, and 36.5% for Asia. The detection of CIN2+ was higher for women from Central and Southern America (23.0‰) or from Eastern Europe (17.9‰), while it was lower for those from Italy (11.9‰), Northern Africa (7.5‰), Sub-Saharan Africa (6.6‰), and from Asia (2.5‰) (p<0.001). CONCLUSIONS: cervical screening programmes should identify and face the barriers to participation of foreign women. This is particularly important for women from geographic areas with a high prevalence of disease, such as Central and Southern America and Eastern Europe.

Long-term performance of colorectal cancerscreening programmes based on the faecal immunochemical test.

BACKGROUND: The long-term performance of colorectal cancer (CRC) screening programmes based on a 2-year faecal immunochemical test (FIT) is still unclear. METHODS: In a sample of 50 to 69-year-olds repeatedly screened with the FIT (OC-Hemodia latex agglutination test; cut-off: 20 µg haemoglobin/g faeces), we examined: (1) the FIT positivity rate, the CRC and advanced adenoma detection rate and the FIT's positive predictive value (PPV) for advanced neoplasia, at each round of screening and (2) the cumulative CRC and advanced adenoma detection rate after five rounds of FIT. RESULTS: Over 12 years (2002-2014), 123 347 individuals were administered the FIT up to six times, and 781 CRCs and 4713 advanced adenomas were diagnosed. The CRC and advanced adenoma detection rates declined substantially from the first to the third (rate ratio (RR) 0.25, 95% CI 0.20 to 0.32) and second (RR 0.51, 95% CI 0.47 to 0.56) rounds, respectively, and then remained stable. The PPV for advanced neoplasia dropped by 18% in the second round (RR 0.82, 95% CI 0.77 to 0.89), with no further reduction thereafter due to a concomitant decline in the FIT positivity rate (RR first to sixth rounds: 0.56, 95% CI 0.53 to 0.60).The cumulative CRC and advanced adenoma detection rates over five consecutive rounds were 8.5‰ (95% CI 7.8 to 9.2), and 58.9‰ (95% CI 56.9 to 61.0), respectively. CONCLUSIONS: Repeated FIT significantly reduces the burden of colorectal disease while facilitating an efficient use of colonoscopy resources. The cumulative detection rate after five rounds of FIT is similar to primary screening with colonoscopy, supporting the need to account for the cumulative sensitivity of repeated FITs when evaluating the test's efficacy.

Dietary inflammatory index before diagnosis and survival in an Italian cohort of women with breast cancer.

The dietary inflammatory indexTM (DII) has been shown to correlate with concentrations of several inflammatory markers and a variety of chronic disease endpoints, including cancers of various anatomic sites. We investigated whether the DII was associated with the risk for death among women with breast cancer (BrCa). This retrospective cohort study included 1453 women with BrCa, diagnosed between 1990 and 1994, and previously enrolled in a case-control study in northern Italy. With a median follow-up of 12·6 years, we observed 503 deaths, among which 398 were due to BrCa. The usual diet was assessed at BrCa diagnosis using a validated FFQ. DII scores were calculated using thirty-one foods/nutrients. Hazard ratios (HR) of death from all causes or from BrCa, with corresponding 95 % CI, were calculated using the Cox models, adjusted for age at diagnosis, tumour stage, oestrogen/progesterone receptor status and other potential confounders. The median DII score of the study women was -1·23, with a relatively narrow range (interquartile range -2·24 to -0·11), indicating a mainly anti-inflammatory diet. There was no difference in survival according to DII tertiles, neither considering all-cause mortality (HRtertile III v. I 1·00; 95 % CI 0·78, 1·28) nor BrCa-specific mortality (HRtertile III v. I 0·97; 95 % CI 0·73, 1·27). Study findings did not suggest an association between the inflammatory potential of diet, measured by the DII, and the survival of BrCa women. However, further studies are needed in populations reporting higher DII scores and a broader range of variability in the scores.

Dietary inflammatory index and prostate cancer survival.

Systemic inflammatory status has been reported to impact survival of prostate cancer (PCa) patients; however, evidence is lacking on whether the inflammatory potential of diet can influence prognosis of PCa patients. To investigate the association between a dietary inflammatory index (DII) and PCa survival, we conducted a retrospective cohort study including 726 men with PCa originally enrolled, between 1995 and 2002, in an Italian case-control study. Information on diet and Gleason score was collected at PCa diagnosis. DII was derived from a food frequency questionnaire using a validated algorithm. Adjusted hazard ratios (HRs) of death with 95% confidence intervals (CIs) were estimated using a Fine-Gray model. DII scores were not significantly associated with all-cause mortality of PCa patients (HR highest vs. lowest DII tertile = 1.25; 95% CI: 0.86-1.83). However, considerable heterogeneity emerged according to Gleason score (p < 0.01): no associations emerged among men with Gleason score 2-6 PCa; whereas, among patients with Gleason score 7-10 PCa, DII was directly associated with both all-cause and PCa-specific mortality (HR highest vs. lowest DII tertile: 2.78; 95% CI: 1.41-5.48; and 4.01; 95% CI: 1.25-12.86; respectively). Among patients with Gleason score 7-10 PCa, ten-year all-cause survival probabilities were 58% (95% CI: 47-67%) for highest and 78% (95% CI: 67-86%) for lowest DII tertile. Study findings support the hypothesis that diet, through its inflammatory potential, may influence the prognosis of patients with more aggressive PCa. Dietary interventions aimed at decreasing inflammation may be considered to improve survival of men with PCa.

Prevalence, characteristics, and survival of children with esophageal atresia: A 32-year population-based study including 1,417,724 consecutive newborns.

BACKGROUND: Esophageal atresia (EA) is a congenital malformation of the upper gastrointestinal tract with an estimated prevalence varying from 1 in 2500 to 1 in 4500 births. The aim of this study was to describe the epidemiology of EA between 1981 and 2012 and evaluate patients' survival. METHODS: This study used data from a population-based Italian Congenital Malformation Registry. The survival status was ascertained by linking the registry records, vital records and the regional registries of patients. Kaplan-Meier methods were used to estimate survival probabilities up to 25 years and Cox proportional hazards regression was used to evaluate factors that affected survival. RESULTS: A total of 407 cases of EA were identified among 1,417,724 total births. After the exclusion of cases with chromosomal anomalies, 49.9% of the patients presented with at least one associated congenital anomaly. The 25-year survival probability was 85.1% (95% confidence interval [CI], 80.8-89.4), with most deaths occurring during the first months of life. Patients' characteristics associated with decreased survival probability were low birth weight (hazard ratio, 3.7; 95% CI, 1.7-8.3) and presence of additional major defects (hazard ratio, 2.8; 95% CI, 1.3-6.0). A significant improvement in survival over the decades was observed for patients with nonisolated EA. CONCLUSION: This study detected a significant improvement in survival of individuals with EA over the past decades and identified the strongest predictors of mortality. These results will be important for the planning of the clinical management and formulation of prognosis when EA is diagnosed in a newborn.

The negative impact of tobacco smoking on survival after prostate cancer diagnosis.

PURPOSE: Tobacco smoking has been found to increase prostate cancer (PCa) mortality in cohorts of healthy men, but its effects on prognosis of men with PCa are still unclear. This study investigated the role of smoking on long-term survival after PCa diagnosis. METHODS: A retrospective cohort including 780 men with incident PCa previously enrolled (between 1995 and 2002) as cases in an Italian case-control study. Information on vital status up to 2013 (median follow-up 13 years) and cause of death were retrieved through health archives. Hazard ratios (HRs) of all-cause and PCa-specific death, and corresponding 95 % confidence intervals (CIs), were calculated using Cox models, adjusting for Gleason score and major confounders. RESULTS: Out of 263 PCa deceased patients, 81 died because of PCa. Smokers at PCa diagnosis reported increased risks of all-cause (HR = 1.5, 95% CI 1.1-2.2) and PCa death (HR = 2.0, 95% CI 1.0-3.8), as compared to never smokers. Dose-response effects emerged according to smoking intensity (HRs for >15 cigarettes/day: 1.9, 95% CI 1.3-3.0, for all causes and 2.3, 95% CI 1.1-4.9, for PCa) and duration (HRs for >45 years: 1.7, 95% CI 1.1-2.6, for all causes and 2.6, 95% CI 1.2-5.5, for PCa). Conversely, former smokers at PCa diagnosis showed no statistically significant higher risks of PCa death. The effects of smoking were consistent in strata of Gleason score. CONCLUSIONS: Current smoking at PCa diagnosis negatively impacted PCa-specific, long-term survival, regardless of Gleason score. Our findings suggest that smoking could be a modifiable risk factor to improve prognosis of men diagnosed with PCa.

Cancer incidence in immigrants by geographical area of origin: data from the Veneto Tumour Registry, Northeastern Italy.

Objective: We investigated whether there are differences in cancer incidence by geographical area of origin in North-eastern Italy. Methods: We selected all incident cases recorded in the Veneto Tumour Registry in the period 2015-2019. Subjects were classified, based on the country of birth, in six geographical areas of origin (Italy, Highly Developed Countries-HDC, Eastern Europe, Asia, Africa, South-central America). Age-standardized incidence rates and incidence rate ratio (IRR) were calculated, for all cancer sites and for colorectal, liver, breast and cervical cancer separately. Results: We recorded 159,486 all-site cancer cases; 5.2% cases occurred in subjects born outside Italy, the majority from High Migratory Pressure Countries (HMPC) (74.3%). Incidence rates were significantly lower in subjects born in HMPC in both sexes. Immigrants, in particular born in Asia and Africa, showed lower rates of all site cancer incidence. The lowest IRR for colorectal cancer was observed in males from South-Central America (IRR 0.19, 95%CI 0.09-0.44) and in females from Asia (IRR 0.32, 95%CI 0.18-0.70). The IRR of breast cancer appeared significantly lower than Italian natives in all female populations, except for those coming from HDC. Females from Eastern Europe showed a higher IRR for cervical cancer (IRR 2.02, 95%CI 1.57-2.61). Conclusion: Cancer incidence was found lower in subjects born outside Italy, with differences in incidence patterns depending on geographical area of origin and the cancer type in question. Further studies, focused on the country of birth of the immigrant population, would help to identify specific risk factors influencing cancer incidence.

Outcomes of SARS-CoV-2 infection in cancer versus non-cancer-patients: a population-based study in northeastern Italy.

INTRODUCTION: This study assesses the risk of infection and clinical outcomes in a large consecutive population of cancer and non-cancer patients tested for SARS-CoV-2 status. METHODS: Study patients underwent SARS-CoV-2 molecular-testing between 22 February 2020 and 31 July 2020, and were found infected (CoV2+ve) or uninfected. History of malignancy was obtained from regional population-based cancer registries. Cancer-patients were distinguished by time between cancer diagnosis and SARS-CoV-2 testing (<12/⩾12 months). Comorbidities, hospitalization, and death at 15 September 2020 were retrieved from regional population-based databases. The impact of cancer history on SARS-CoV-2 infection and clinical outcomes was calculated by fitting a multivariable logistic regression model, adjusting for sex, age, and comorbidities. RESULTS: Among 552,362 individuals tested for SARS-CoV-2, 55,206 (10.0%) were cancer-patients and 22,564 (4.1%) tested CoV2+ve. Irrespective of time since cancer diagnosis, SARS-CoV-2 infection was significantly lower among cancer patients (1,787; 3.2%) than non-cancer individuals (20,777; 4.2% - Odds Ratio (OR)=0.60; 0.57-0.63). CoV2+ve cancer-patients were older than non-cancer individuals (median age: 77 versus 57 years; p<0.0001), were more frequently men and with comorbidities. Hospitalizations (39.9% versus 22.5%; OR=1.61; 1.44-1.80) and deaths (24.3% versus 9.7%; OR=1.51; 1.32-1.72) were more frequent in cancer-patients. CoV2+ve cancer-patients were at higher risk of death (lung OR=2.90; 1.58-5.24, blood OR=2.73; 1.88-3.93, breast OR=1.77; 1.32-2.35). CONCLUSIONS: The risks of hospitalization and death are significantly higher in CoV2+ve individuals with past or present cancer (particularly malignancies of the lung, hematologic or breast) than in those with no history of cancer.

Quality control on digital cancer registration.

Population-based cancer registration methods are subject to internationally-established rules. To ensure efficient and effective case recording, population-based cancer registries widely adopt digital processing (DP) methods. At the Veneto Tumor Registry (RTV), about 50% of all digitally-identified (putative) cases of cancer are further profiled by means of registrars' assessments (RAs). Taking these RAs for reference, the present study examines how well the registry's DP performs. A series of 1,801 (putative) incident and prevalent cancers identified using DP methods were randomly assigned to two experienced registrars (blinded to the DP output), who independently re-assessed every case. This study focuses on the concordance between the DP output and the RAs as concerns cancer status (incident versus prevalent), topography, and morphology. The RAs confirmed the cancer status emerging from DP for 1,266/1,317 incident cancers (positive predictive value [PPV] = 96.1%) and 460/472 prevalent cancers (PPV = 97.5%). This level of concordance ranks as "optimal", with a Cohen's K value of 0.91. The overall prevalence of false-positive cancer cases identified by DP was 2.9%, and was affected by the number of digital variables available. DP and the RAs were consistent in identifying cancer topography in 88.7% of cases; differences concerned different sites within the same anatomo-functional district (according to the International Agency for Research on Cancer [IARC]) in 9.6% of cases. In short, using DP for cancer case registration suffers from only trivial inconsistencies. The efficiency and reliability of digital cancer registration is influenced by the availability of good-quality clinical information, and the regular interdisciplinary monitoring of a registry's DP performance.

Adherence to Mediterranean Diet, Physical Activity and Survival after Prostate Cancer Diagnosis.

Despite the considerable number of studies investigating the Mediterranean diet in prostate cancer (PCa) etiology, very few focused on cancer survival. We assessed the pre-diagnostic diet and physical activity in a cohort of 777 men with PCa diagnosed between 1995 and 2002 in north-eastern Italy; adherence to the Mediterranean diet was evaluated through the Mediterranean Diet Score (MDS). Hazard ratios (HR) of death with confidence intervals (CI) were estimated using the Cox model, adjusting for potential confounders. During 10 years of follow-up, 208 patients (26.8%) died, 75 (9.7%) due to PCa. Patients reporting MDS ≥ 5 showed a higher overall survival than those with MDS < 5 (HR = 0.74; 95% CI: 0.56-0.99). Although high physical activity was not significantly associated with overall survival (HR = 0.79; 95% CI: 0.59-1.07), the HR for all-cause death was the lowest (HR = 0.58; 95% CI: 0.38-0.90) for men reporting MDS ≥ 5 and high physical activity compared to those reporting MDS < 5 and low/moderate physical activity. No association emerged for PCa specific survival. Study findings support the beneficial impact of pre-diagnostic adherence to the Mediterranean diet and physical activity on overall survival; they are mainly driven by risk reduction in non-prostate cancer mortality, which however accounts for about 80% of death in men with PCa.

Adherence to the Mediterranean Diet and Mortality after Breast Cancer.

Adherence to Mediterranean diet has been consistently associated with a reduced mortality in the general population, but evidence for women with breast cancer is scanty. METHODS: A cohort of 1453 women with breast cancer diagnosed between 1991 and 1994 in northern Italy was followed-up for vital status for 15 years after diagnosis. The pre-diagnostic habitual diet was assessed through a structured questionnaire and adherence to the Mediterranean diet was evaluated through the Mediterranean Diet Score. Hazard ratios (HR) of death with confidence intervals (CI) were estimated using Cox model, adjusting for potential confounders. RESULTS: Compared to women who scarcely adhere to the Mediterranean diet (n = 332, 22.8%), those highly adherent (n = 500, 34.4%) reported higher intakes of carbohydrates, mono-unsaturated and poly-unsaturated fatty acids, vitamins, folate, and carotenoids, and lower intakes of cholesterol and animal proteins. Adherence to the Mediterranean diet was associated with a better prognosis: 15-year overall survival of 63.1% for high and 53.6% for low adherence, respectively (p = 0.013). HR for all-cause mortality was 0.72 (95% CI: 0.57-0.92) and HR for breast cancer mortality was 0.65 (95% CI: 0.43-0.98) for women 55 years and older. No significant association emerged for breast cancer mortality in the total cohort. CONCLUSIONS: Although dietary habits may have changed after breast cancer diagnosis, these findings indicate that women who ate according to the Mediterranean dietary pattern prior to their diagnosis may have greater chance of a favorable prognosis after breast cancer diagnosis compared to those who did not.

Effect of obesity and other lifestyle factors on mortality in women with breast cancer.

A few lifestyle characteristics before cancer diagnosis have been suggested to modify the prognosis of breast cancer. Follow-up information from 1,453 women with incident invasive breast cancer, diagnosed between 1991 and 1994 and interviewed within the framework of an Italian multicenter case-control study, was used to assess the effect of obesity and of a large spectrum of other factors on breast cancer mortality. Five hundred and three deaths, including 398 breast cancer deaths, were identified. Hazard ratios (HR) for all-cause and breast cancer mortality and corresponding 95% confidence intervals (CI), were calculated using Cox proportional hazards models and adjusted for age and breast cancer characteristics (stage and receptor status). Increased risk of death for breast cancer emerged for body mass index (BMI) >/= 30 kg/m(2) (HR = 1.38; 95% CI: 1.02-1.86), compared to <25, or waist-to-hip ratio (WHR) >/= 0.85 (HR = 1.27; 95% CI: 0.98-1.64), compared to <0.80, and the strongest association was observed for women with BMI >/=30 and high WHR (>/=0.85), compared to women with BMI <25 and WHR < 0.85 (HR = 1.57, 95% CI: 1.08-2.27). The unfavorable effect of high BMI was similar in women <55 and >/=55 years of age, whereas it was stronger in women with I-II stage than III-IV stage breast cancer. Low vegetable and fruit consumption and current or past smoking were also associated to marginally worse breast cancer survival. No significant relationship with survival after breast cancer emerged for several other major lifestyle factors, including physical activity, alcohol drinking, exogenous hormones use and fat intake. High BMI was the lifestyle risk factor that most consistently modified breast cancer prognosis in our study.

Fruit and vegetables consumption is directly associated to survival after prostate cancer.

SCOPE: Since the evidence on the role of diet on prostate cancer (PCa) prognosis is still controversial, we evaluated the long-term effects of fruit and vegetables consumption on survival after PCa. METHODS AND RESULTS: A retrospective cohort study included 777 men with PCa diagnosed between 1995 and 2002 in north-eastern Italy and followed up to 2013. A validated food frequency questionnaire assessed the usual diet in the 2 years before PCa diagnosis, including detailed fruit and vegetables consumption. Adjusted hazard ratios (HRs) of death with 95% confidence intervals (CIs) were estimated using Fine-Gray models. PCa patients with a consumption of both fruit and vegetables above the median showed a higher 15-year overall survival probability than those with lower intakes (71% versus 58%, p = 0.04; HR = 0.66, 95% CI: 0.47-0.93). Consumption of foods rich in fiber (HR = 0.59, 95% CI: 0.41-0.86) and proanthocyanidins (HR = 0.58, 95% CI: 0.40-0.82) were inversely associated with overall mortality. Interestingly, proanthocyanidins (HR = 0.52; 95% CI: 0.27-0.98) and flavonols (HR = 0.40; 95% CI: 0.19-0.84) were inversely associated also with PCa-specific mortality. CONCLUSION: High consumption of fruit and vegetables offers an advantage in survival among the rising number of men living after a PCa diagnosis, possibly through the epigenetic effect of some nutrients.

Quality control of mammography screening in the Veneto Region. Evaluation of four programs at a local health unit level--analysis of the frequency and diagnostic pattern of interval cancers.

AIMS AND BACKGROUND: Service mammography screening has been reported to have suboptimal performance compared to controlled trials. The aim of this study was to evaluate the sensitivity of the mammography screening program in four Local Health Units (ASL) and the possible causes of diagnostic error in cases further surfacing as interval cancers. MATERIAL AND METHODS: Interval cancers were identified by cross checking of screened women databases with hospital discharge records reporting breast cancer. Proportional interval cancer incidence (observed interval cancers/expected invasive cancers) was determined by matching the database of women screened during 1999-2002 to the hospital discharge records databases during 1999-2003. The ratio of observed interval cancer rate to underlying incidence was compared to international standards and with literature data. Screening mammograms reported as negative and followed by interval cancers were randomly mixed with true-negative controls, and the resulting set underwent blind review by an external radiologist who applied the conventional criteria recommended for the classification of the type of diagnostic error (occult, minimal signs, screening error). RESULTS: Matching of screening archives with the hospital discharge records databases allowed for the identification of 154 invasive interval cancers compared to 480 expected. The proportional observed/expected interval cancer incidence in the first and second year of the interval was 21% and 46%, respectively (ASL 1 = 14% or 38%, ASL 2 = 19% or 48%, ASL 3 = 30% or 53%, ASL 4 = 25% or 49%). Radiological review included 38 further interval cancer cases, identified after the time limits defined for proportional interval cancer incidence assessment, and could not include 18 interval cancers, not retrieved from ASL 4 archives: overall, 174 interval cancers were reviewed, of which 135 were classified as occult (77.3%) (ASL 1 = 83.3%, ASL 2 = 71.1%, ASL 3 = 78.6%, ASL 4 = 75%), 12 (6.9%) as minimal signs (ASL 1 = 6.6%, ASL 2 = 11.5%, ASL 3 = 2.4%, ASL 4 = 5%), and 27 (15.5%) as screening error (ASL 1 = 8.3%, ASL 2 = 17.3%, ASL 3 = 19.0%, ASL 4 = 25%). CONCLUSIONS: Observed proportional interval cancer incidence was lower than commonly reported for service screening programs and currently recommended (< 30% in the first, < 50% in the second year of the interval). The analysis of interval cancer causes showed a screening error rate below the maximum acceptable standard (< 20% of interval cancers should be classified as screening error) in three of four programs and in average figures. Substantial differences observed among single programs (one did not comply to recommended standards) suggest that space is available for the improvement of overall performance by optimizing program organization and by further training of radiologists. Overall, the analysis showed a good sensitivity of the screening program in the Veneto Region, although the performance was inferior to that of excellence centers, and further action to improve it is possible. Assessment and review of interval cancers is an early indicator of screening efficacy which has not yet been fully adopted in Italian screening programs. Although using hospital discharge records to identify interval cancers may be affected by limited errors, such a procedure is particularly convenient, as data from hospital discharge records are available much in advance compared to cancer registries and are the most reliable source of information for areas uncovered by a cancer registry. Hospital discharge records-based procedures for interval cancers assessment should be employed routinely in screening programs.

[An increased mortality from lung cancer among workers of a bright electroplating factory]. / Aunmentata mortalità per tumori polmonari tra gli addetti a una cromatura a strato sottile.

OBJECTIVE: to evaluate cancer mortality especially from lung tumours, in a cohort of workers of a bright electroplating factory, an industrial activity suspected of increasing the risk of cancer because of exposure to hexavalent chromium. Workers of this and other similar factories have been the target of a health surveillance program in the early '80s. DESIGN: the cohort members have been selected from the roster of employees as workers or technical clerks with at least 6 month of presence between the beginning of the activity (January 1968) until December 1994. Vital status has been updated to December 2003. The mortality rates of both the Italian and regional population have been used as standards. RESULTS: mortality from lung cancer was strongly increased among workers (based on 7 deaths among males, and one among females). Among males, lung cancer mortality was stratified by duration of work, latency and period of entry: the excess is evident in all categories and appeared higher among the workers recruited in more recent years. CONCLUSION: we suggest that the results are in agreement with the hypothesis of an occupational exposure to a carcinogenic hazard, as observed in other studies, and correlates with the increase of chromosomal aberrations observed in the past among these workers. This type of industrial activity deserves more epidemiological studies and close attention on the side of industrial hygiene.

The impact of diabetes and other metabolic disorders on prostate cancer prognosis.

AIMS: To investigate the impact of diabetes mellitus (DM) and other metabolic disorders on the survival of men with prostate cancer (PCa). METHODS: We conducted a retrospective cohort-study based on 715 men with PCa, originally enrolled in an Italian case-control study between 1995 and 2002. Anthropometric measures, self-reported medical conditions, and Gleason score were assessed at enrollment. Adjusted hazard ratios (HRs) of death, with 95% confidence intervals (95% CIs), were estimated using Fine and Gray's regression model. RESULTS: After a median follow-up of 11.6years, 244 (34.1%) deaths occurred, 77 (31.6%) due to PCa. Excess mortality from all causes was reported in PCa patients with DM (HR=1.56, 95% CI: 1.03-2.36), which increased to 1.76 (95% CI: 0.99-3.13) when at least two out of three metabolic disorders (i.e., waist circumference ≥102cm, drug-treated hypertension, and hypercholesterolemia) were additionally present. The impact of metabolic disorders was stronger on non-PCa-specific mortality with HRs equal to 2.21 (95% CI: 1.38-3.54) for DM, 1.45 (95% CI: 0.97-2.19) for waist circumference ≥102cm, and 1.63 (95% CI: 1.19-2.22) for drug-treated hypertension. CONCLUSIONS: DM and other metabolic disorders unfavorably affected the survival of PCa patients, mainly impacting on the risk of death from causes other than PCa.
