    Immigration is a growing flow in Italy. Also specific health needs could be imported. We focused on cancer. A systematic search for literature in PubMed was performed on 10th March 2016, limited to articles published between 1st March 1996 and 1st March 2016. Papers were reviewed focusing on: specific risks, prevention and care. Cancer incidence is generally lower for immigrants than for natives, also for the health immigrant effect. However, cancers with an infective etiology may have, among some groups of immigrants, a great relevance. Primary or secondary cancer prevention could be greatly improved among immigrants. Moreover, another specific aspect of immigration is at seeking cancer care for children. Specific preventive strategies should be customized for immigrants to get higher compliance, e.g. for those at high risk for cervical cancers. Moreover, the capability of the Italian health system to cope more comprehensively with sick immigrated children and their families should be improved

    Objective: In many Western countries, survival from vulvar squamous cell carcinoma (VSCC) has been stagnating for decades or has increased insufficiently from a clinical perspective. In Italy, previous studies on cancer survival have not taken vulvar cancer into consideration or have pooled patients with vulvar and vaginal cancer. To bridge this knowledge gap, we report the trend in survival from vulvar cancer between 1990 and 2015. (2) Methods: Thirty-eight local cancer registries covering 49% of the national female population contributed the records of 6274 patients. Study endpoints included 1- and 2-year net survival (NS) calculated using the Pohar-Perme estimator and 5-year NS conditional on having survived two years (5|2-year CNS). The significance of survival trends was assessed with the Wald test on the coefficient of the period of diagnosis, entered as a continuous regressor in a Poisson regression model. (3) Results: The median patient age was stable at 76 years. One-year NS decreased from 83.9% in 1990–2001 to 81.9% in 2009–2015 and 2-year NS from 72.2% to 70.5%. Five|2-year CNS increased from 85.7% to 86.7%. These trends were not significant. In the age stratum 70–79 years, a weakly significant decrease in 2-year NS from 71.4% to 65.7% occurred. Multivariate analysis adjusting for age group at diagnosis and geographic area showed an excess risk of death at 5|2-years, of borderline significance, in 2003–2015 versus 1990–2002. (4) Conclusions: One- and 2-year NS and 5|2-year CNS showed no improvements. Current strategies for VSCC control need to be revised both in Italy and at the global level

    Background The 8th edition of TNM has introduced new rules for staging cutaneous melanoma. Objective To compare TNM 7th and 8th editions in defining pathological stages of melanoma. Methods A population-based series of 1847 skin melanoma from Romagna cancer registry (Italy) incident during 2003-2012 has been used to measure the agreement (with Cohen's kappa) between TNM 8th and 7th editions in defining melanoma stage. Disease-specific survival has been computed for each stage according to TNM 7th and 8th. Results The agreement between the two TNM editions was quite good when considered on average (kappa = 70.7%), moderate for stage I (61.5%), nearly perfect for stage II (95.0%), but extremely poor for stage III (8.1%). The overall melanoma-specific observed survival was 90.8% at 5 year and 88.9% at 10 year with a strong prognostic effect of stage. Conclusion TNM 8th edition introduces several changes which do not seem really helpful in addressing the care of stage I melanoma and may complicate the definition and comparability of stage III

    Background: It has been suggested that progression of superficial bladder cancer may be regulated at the molecular level by a typical pattern of expression of genes involved in apoptosis. Recently LIVIN, belonging to the inhibitors of apoptosis (IAP) family, has been found to be expressed in most solid tumors, where its expression is suggested to have prognostic significance. No data are available concerning the significance of LIVIN in the progression of bladder tumors. Patients and methods: In the present paper we used RT-PCR to investigate the expression of LIVIN isoforms α and β, SURVIVIN, BCL-X and BCL-2/BAX expression ratio both in normal and tumoral bladder tissues, and correlated their expression with the emergence of early relapses in a follow-up of 4 years. This study shows that only the α isoform of LIVIN, which is not expressed in normal bladder tissue, is expressed in a proportion of tumors with a high risk of relapse. Results: LIVIN was found in 7/30 patients (23%), SURVIVIN in 9/30 (30%), BCL-2/BAX ratio >1 in 16/30 (53%), BCL-2/BAX expression ratio <1 in 14/30 (46.6%) and BCL-X, only in isoform BCL-XL, in 11/30 (36.6%). When we evaluated the dependence between each gene expression and relapse free time of patients, we found that LIVIN, high BCL-2/BAX ratio and BCL-XL, but not SURVIVIN, reached statistical significance in order to predict relapses. Conclusions: Our findings suggest that LIVIN may be involved in the progression of superficial bladder cancer and used as a marker of early recurrence; while the expression of SURVIVIN cannot be used to identify patients with high risk of relapse

    We investigated the expression of the anti-apoptotic genes bcl-2 and bcl-X and the pro-apoptotic gene bax in bladder tumors and normal samples from urinary bladder, using RT-PCR analysis. Bcl-2 mRNA was not detected in any of the normal samples, while it was found expressed in 66% of the low stage tumors and in 100% of the high stage tumors. Bax expression had an inverse progress, being present in 62% of the normal tissues examined, in 16% of the low stage tumors and in 14% of the high stage. Bcl-X gene expression was quite variable among all samples (37% in normal tissues, 50% in the low stage tumors and 14% in the high stage), bcl-X mRNA was only found in the isoform bcl-X-L, with anti-apoptotic functions, whereas no sample expressed the isoform bcl-X-S, which is known to suppress bcl-2 functions. Most samples expressing bcl-2 did not express bcl-X, and vice versa. These results, besides confirming the potential role of these genes in the pathogenesis of low stage bladder cancer strengthen the hypothesis concerning their possible interaction in the progression of disease

    Follicle-stimulating hormone, testosterone, and hypoxia differentially regulate UDP-glucuronosyltransferase 1 isoforms expression in rat Sertoli and peritubular myoid cells

    Uridine diphosphoglucuronosyltransferases (UGTs) are detoxifying enzymes responsible for the metabolism of endogenous and xenobiotics compounds. UGT isoforms are widely distributed in rat tissues showing a constitutive acid inducible gene expression. However, little information is available concerning UGTs expression in testis. The UGT1A1, UGT1A2, and UGT1B1 mRNAs expression in whole rat testis, in Sertoli and peritubular myoid cells in basal conditions, and after hormonal and hypoxic stimulation were investigated by reverse transcriptase-polymerase chain reaction (RT-PCR). Constitutive expression of each UGT1 isoform was present in rat testis with higher levels of UGT1A2. UGT transcripts were also detected in Sertoli and peritubular myoid cells. After FSH stimulation, Sertoli cells showed an increase in UGT1B1 mRNA expression. whereas the levels of UGT1A1 and UGT1A2? resulted unmodified. The main effect induced by testosterone was a decrease of UGT1B1 mRNA expression in peritubular myoid cells, whereas in Sertoli cells an increase in UGT1A1 and UGT1B1 was observed. In hypoxic conditions, a reduction in UGTs mRNA levels was detected in both cell types. These findings suggest that rat UGT1 isoforms are regulated in testis by hormonal and environmental factors. Thus, it was speculated that alterations in UGTs expression and/or activity may be involved in the pathogenesis of testis injury, (C) 2000 Elsevier Science Ltd. All rights reserved

    Kidney and liver are the major organs of erythropoietin (Epo) synthesis. However, Epo messenger RNA (mRNA) has been detected in several organs, such as brain, lung, and testis. Furthermore, functional Epo receptors have been demonstrated on different cell types, including rat Leydig cells. The aim of the study was to identify testicular cells expressing Epo mRNA and to quantitate its levels by competitive reverse transcriptase-polymerase chain reaction (RT PCR). Besides whole testis, Epo transcripts were found in Sertoli and peritubular myoid cells, while no signal was detected in Leydig cells. Exposure of Sertoli cells to CoCl2 led to an increase of Epo mRNA level. Semiquantitative competitive RT PCR presented an increase in the level of Epo mRNA in sertoli cells stimulated by follicle-stimulating hormone, while exposure of peritubular myoid cells cultures to testosterone reduced Epo mRNA expression. Due to the blood-testis barrier, basal expression of Epo suggests a not yet defined function of this hormone in testis. (C) 2001 by The American Society of Hematology

    The impact of the organised cervical cancer (CC) screening programmes implemented in Europe since the 1990s has been insufficiently evaluated. We investigated the changes in CC incidence following the introduction of a screening programme in the Emilia-Romagna Region (northern Italy). The study period was 1988–2013. The programme, targeting women aged 25–64 years (1,219,000 in 2018), started in 1998. The annual incidence rates that would be expected in 1998–2013 in the absence of screening were estimated, first, by analysing the annual rates in 1988–1997 with a log-linear model and, second, by analysing the annual rates in 1988–2013 with an age-period model in which the period effect was enforced to be linear. Cervical adenocarcinoma incidence trend over the entire period was used to validate both estimates. Observed annual rates were compared to the two series of expected ones with the incidence rate ratio (IRR). Incidence remained stable during 1988–1997, peaked in 1998 and then decreased until 2007, when it stabilised. The two series of expected rates were virtually coincident and their trends roughly paralleled the stable adenocarcinoma incidence trend. After 2007, the median IRR was 0.60 (95% confidence interval, 0.45–0.81) based on the log-linear model and 0.58 (95% confidence interval, 0.34–0.97) based on the age-period model. Thirty-six to seventy-five CC cases were prevented annually for an average annual frequency of 6.5 per 100,000 women in the target population. In summary, consistent circumstantial evidences were obtained that the organised screening programme brought about a 40% reduction in annual CC incidence after 10 years
