Abstract
BACKGROUND Very little data exist on the epidemiology of cholangiocarcinoma in Italy. AIM We focus on the descriptive epidemiology of cholangiocarcinoma in Italy. METHODS Data on incidence were obtained from the Italian Association of Tumour Registries while mortality data were obtained from the Italian National Institute of Statistics. RESULTS A progressive increase of incidence with age was seen for extra-hepatic, intra-hepatic and not otherwise specified cholangiocarcinoma. Crude incidence rates were higher for extra-hepatic cholangiocarcinoma than those for intra-hepatic cholangiocarcinoma and in men compared to women. An increasing incidence trend was observed, from 1988 to 2005, for both extra-hepatic- and intra-hepatic cholangiocarcinoma with a 3-6% yearly increase and with a rate of increase higher for men than for women and for intra-hepatic- than for extra-hepatic cholangiocarcinoma. For intra-hepatic cholangiocarcinoma, the mortality rates progressively increased from 0.15 per million in 1980 to 5.9 per million in 2003, when mortality for this cancer surpassed extra-hepatic cholangiocarcinoma. Mortality rates for extra-hepatic cholangiocarcinoma showed an increasing trend from 1980 to 1994 but, in contrast to intra-hepatic cholangiocarcinoma, a stable or slightly decreasing trend from 1995 to 2003 was observed. CONCLUSIONS In Italy, cholangiocarcinoma showed a progressive increase in incidence and mortality in the last two decades mainly in intra-hepatic cholangiocarcinoma.

Abstract
The seventh edition of TNM classification of malignant tumours has been published by the International Union against Cancer in late 2009 and it is now available also in Italian language. This new edition introduces some major revisions and several updates of cancer staging rules. New criteria based on pathological details, biological assessment of lesions and new prognostic groupings have been established. Clinicians, pathologists, epidemiologists have now the chance to get familiar with those novelties, that are expected to be of great help in a moment like the present one, when strong evolutions occur in the strategies of diagnosis and of treatment of cancer.

Abstract
The aim of the study was to evaluate the roles of screening activation and hormone replacement therapy discontinuation on the recent declining breast cancer incidence trends in Italy. We analyzed 41,358 invasive female breast cancers incident during 1991-2004 in six Italian population-based cancer registries. Overall and age-specific incidence trends were evaluated using Joinpoint analysis. In addition to calendar years, data were analyzed on a years-since-screening-activation basis. Annual percentage change of standardized rates was computed. There were statistically significant increasing trends for women 40-44 and 45-49 years that did not change after screening activation. On the contrary, for women 50-69 years old and for those 70+ years, the increasing trends flattened around 2 years after screening activation. The prevalence of hormone replacement therapy use in Italy is and was rather low. In conclusion, the recent tendency toward stabilization observed in Italy for female breast cancer incidence rates in women aged 50 years or more follows the introduction of mammographic screening.

Abstract
INTRODUCTION The horseshoe kidney is the most frequent renal anomaly, with a prevalence of 0.25% and a male to female ratio of 3:1. Although the pathogenesis remains controversial, the consequences of the impaired urinary drainage are well known: up to two third of patients present with urinary stasis, infection and urolithiasis. Percutaneous nephrolithotomy (PCNL) is a successful procedure for urolithiasis in horseshoe kidneys. MATERIALS AND METHODS A 9-year-old patient with a 4-cm stone associated with horseshoe kidney underwent Percutaneous nephrolithotomy (PCNL). During the procedure, a flexible uretheroscopy was performed in order to obtain a complete vision and an optimal management of the procedure. RESULTS At the end of the procedure, the patient was stone-free. We reported no hemorrhagic complications, no pain and no infection. The patient was discharged after 48 hours. CONCLUSIONS The procedure is safe and effective, as long as the surgeon pays attention to the recommendations below.

Abstract
OBJECTIVE the study evaluates the accuracy of an algorithm based on hospital discharge data (HDD) in order to estimate breast cancer incidence in three italian regions (Emilia-Romagna, Toscana and Veneto) covered by cancer registries (CR). The evolution of computer-based information systems in health organization suggests automatic processing of HDD as a possible alternative to the time-consuming methods of CR. The study intends to verify whether HDD quickly provides reliable cancer incidence estimates for diagnosis and therapy evaluations. DESIGN AND SETTING an algorithm based on discharge diagnosis and surgical therapy of hospitalized breast cancer patients was developed in order to provide breast cancer incidence. Results were compared with the corresponding incidence data of cancer registries. The accuracy of the automatic method was also verified by a direct record-linkage between HDD output and registries' files. The overall survival of cases lost to "HDD method" was analyzed. RESULTS in the period covered by the study (3,125,425 person/year) CR enrolled 6,079 incident cases, compared to 6,000 cases recorded through the HDD flow. Incidence rates of the two methods (CR 194.5; HDD 192.0 x 100.000) showed no statistical differences. However, matched cases by the two methods were only 5,038. The sensitivity of the HDD algorithm was 82.9% and its predictive positive value (PPV) was 84.0%. False positive cases were 9.9%. On the other hand, 12.3% CR incident cases were not identified by the algorithm: these were mainly made up of older women, not eligible for surgical therapy. Their three-years survival was 62.0% vs 88.8% of the whole incidence group. CONCLUSION HDD flow performance was similar to observations reported in the literature. The agreement between HDD and CR incidence rates is a result of a cross effect of both sensitivity and specificity limitations of the HDD algorithm. This can seriously impair the reliability of the latter method with regard to the evaluation of diagnostic and therapeutic strategies in cohort studies (i.e. the most effective approach to health setting in oncology).s.

Abstract
1518 Background: Lung cancer phase II chemoprevention trials have not focused so far on the peripheral lung. CT discovers small, undetermined peripheral nodules, which may be preinvasive lesions. In a recent phase II trial the glucocorticoid Budesonide reduced peripheral nodules at spiral CT. Methods: We performed a randomized, double-blind, placebo-controlled, phase IIb clinical trial of inhaled budesonide in current (CS) or former smokers (FS) with CT-detected peripheral nodules. Primary endpoint: shrinkage effect on nodules. Secondary endpoints: decrease in size/number of the target lesions, modulation of tumor markers in sputum and plasma, toxicity, effect on pulmonary function. Two hundred and two subjects received 800μg budesonide (B) twice daily or placebo (P) for 1 year. CT scans at 0 and 12 months (mts), and clinical evaluation + serum/plasma collection at 0, 3, 6, and 12 months were performed. Subjects were stratified according to gender, smoking habits (CS vs. FS), and nodule characteristics (solid vs. non-solid). Results: Preliminary data had shown no shrinkage of the nodules in the B treated arm in a per subject analysis (primary objective). We present now results on serum markers (ultrasensitive C-reactive protein, CRP), emphysema and pulmonary function. As compared to baseline, CRP median levels show at 12 months a nonsignificant (p = 0.85) reduction: -0.25 ± 0.63 (B) vs. -1.16 ± 0.97 (P). 12-month values are significantly (p = 0.01) associated with baseline values and smoking status, with higher mean values at 12 months in FS (B 2.1 ± 2.0 vs. P 3.4 ± 1.9). Emphysema values at 12 months are significantly higher (p = 0.0022) in the B (+ 0.29 ± 0.06) versus P arm (+ 0.12 ± 0.07). This difference is not correlated to sex (p = 0.7062) and smoking status (p = 0.8044). As regards spirometry, no significant difference on FEV 1% and DLC/VA appears between arms at 12 months: median FEV 1% values 3.7 ± 1.0 for B versus 2.9 ± 1.0 for P (p = 0.6221); median DLC/VA increase of 0.3 ± 1.9 (B) versus decrease of -3.8 ± 1.6 (P) (p = 0.4191). Conclusions: A significant effect of B on ultrasensitive-CRP and pulmonary function has not been shown. CRP results may indicate the lack of systemic absorption of B. Emphysema appears slightly worse in the B arm, particularly in FS; this is worth further investigation. No significant financial relationships to disclose.

Abstract
Development of new drugs and optimal application of the drugs currently in use in clinical chemotherapy requires the application of biomarkers. Ideally, these biomarkers would stratify patients so that only those patients likely to respond to a particular therapy receive that therapy. However, that is not always feasible, and an alternative is to make use of early response biomarkers to determine the responding population. In this paper, a number of generic (i.e. not necessarily specific to the action mechanism of the compound) early-response biomarkers are discussed and compared in different models and with three compounds with quite different mechanisms of action: a VEGF-R inhibitor (PTK787), an mTOR inhibitor (RAD001) and a microtubule stabiliser (EPO906). The methods include noninvasive DCE-MRI and PET imaging for measuring tumour vascularity, metabolism and proliferation, as well as the minimally invasive WIN method for measuring tumour interstitial pressure (IFP). The data show that drug-induced changes in IFP (delta IFP) involve mechanism-dependent changes in the tumour vascular architecture, and that delta IFP may be considered a universal generic early-response marker of tumour response to therapy.

Abstract
The aim of this study was the evaluation of the impact of service screening programmes on breast cancer mortality in five regions of Italy. We conducted a matched case-control study with four controls for each case. Cases were defined as breast cancer deaths occurred not later than 31 December 2002. Controls were sampled from the local municipality list and matched by date of birth. Screening histories were assessed by the local, computerised, screening database and subjects were classified as either invited or not-yet-invited and as either screened or unscreened. There were a total of 1750 breast cancer deaths within the 50 to 74-year-old breast cancer cases and a total of 7000 controls. The logistic conditional estimate of the cumulative odds ratios comparing invited with not-yet-invited women was 0.75 (95% CI: 0.62-0.92). Restricting the analyses to invited women, the odds ratio of screened to never-respondent women corrected for self-selection bias was 0.55 (95% CI: 0.36-0.85). The introduction of breast cancer screening programmes in Italy is associated with a reduction in breast cancer mortality attributable to the additional impact of service screening over and above the background access to mammography.

Abstract
Systemic lupus erythematosus (SLE) is an autoimmune disease mainly mediated by the deposit of immune complexes and defects in T lymphocytes and antigen-presenting cells along with a high production of T-helper 2 cytokines. A tolerance-inducible function of nonclassical class Ib human leukocyte antigen (HLA)-G molecule in innate and adaptive cellular responses has been reported, suggesting a role in inflammatory diseases. A 14 bp sequence insertion/deletion polymorphism (rs16375) in the 3'-untranslated region of the HLA-G gene has been associated to the stability of HLA-G messenger RNA. The insertion of the 14 bp sequence seems to be associated with lower levels of soluble HLA-G (sHLA-G). The aim of this study was to evaluate the possible association of the presence of the 14 bp sequence (+14 bp) with SLE. We have HLA-G genotyped 200 SLE patients and 451 healthy control subjects (HS; Italian) and analyzed the plasma levels of sHLA-G and interleukin-10 (IL-10) in a subset of SLE patients and healthy subjects (Italian and Danish). A significant increase of the +14 bp HLA-G allele was detected in the Italian SLE patients compared with HS [P = 0.003, OR 1.44 (95% CI 1.13-1.82)]. A significant increased frequency of HLA-G +14/+14 bp and a decreased frequency of HLA-G -14/-14 bp were observed in SLE patients. There median concentration of sHLA-G was significantly lower in the plasma of SLE patients compared with that in the plasma of healthy controls (P < 0.0001). Furthermore, the results confirmed higher concentrations of IL-10-positive plasma in SLE patients. These results support a potential role for HLA-G in the susceptibility of SLE.

Abstract
Multiplayer Online Games (MOGs) embody intensive applications that require smart solutions able to cope with the high network traffic generated by players, variable latencies, and system failures. To this aim, the anatomy of the game architecture should reflect the possibly wide geographical dispersion of players interacting in a game session. Whereas the use of mirrored game servers has been recognized as a scalable solution to support MOGs, yet, a critical aspect remains that of identifying an efficient synchronization scheme able to responsively guarantee the consistency of the redundant game state. To address this issue, we added intelligence to an optimistic synchronization scheme for mirrored game server architectures: our scheme is able to classify events and, based on their semantics, relax ordering and reliability constraints to gain responsiveness without sacrificing consistency. In this work, we describe the devised scheme and report on an experimental assessment that is based on a real implementation of a mirrored game server architecture, deployed over the Internet. Results definitively show the efficacy of our approach.

Abstract
Living with a chronic disease is for the patient a ''disease experience'' that also affects the psychosocial sphere and has a negative impact on perceived quality of life. To estimate the effect of dialysis on the perceived quality of life and to identify by means of a specific questionnaire the aspects that are compromised most. From our results it emerged that the examined patients had a sufficiently good total perception of quality of life, even though about 30% of the patients reported critical aspects related to daily life and, in some age groups, also related to dialysis method. This study confirms the importance of developing educational and supportive predialysis programs in order to identify and reduce the critical aspects.

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
Low-dose CT is widely employed for the early diagnosis of lung cancer in high-risk populations even if screening programmes have not been clinically validated yet; however, the optimum follow-up schedule for small lung nodules of uncertain status has not been defined. The aim of this study was to assess outcomes for small pulmonary nodules (diameter < or =5 mm) detected by CT in asymptomatic smokers In 2000-2001, 1035 high-risk people were enrolled in an observational study for the early detection of lung cancer by yearly CT. The prevalence, incidence and evolution of small lung solid nodules are described 238 solid lung nodules < or = 5 mm were identified at initial low-dose CT in 165 people (prevalence 15.9%). 26% of them were not detected in the following 4 years, 43.3% did not change and 10.1% grew to >5 mm; three were removed and found to be malignant (all T1N0); the remaining 21 were followed yearly In the following year, 79 new small nodules were detected (incidence 7.9%). 11.4% were not detected in the subsequent 3 years, 79.7% did not change, 2.5% grew to > 5 mm and were followed yearly In conclusion, prevalent and incident nodules < or =5 mm detected by low-dose CT screening for lung cancer can be safely checked at 1 year intervals.

Abstract
The aim of this study was to evaluate the efficacy of a mobile laminar airflow (LAF) unit in reducing bacterial contamination at the surgical area in an operating theatre supplied with turbulent air ventilation. Bacterial sedimentation was evaluated during 76 clean urological laparotomies; in 34 of these, a mobile LAF unit was added. During each operation, settle plates were placed at four points in the operating theatre (one at the patient area and three at the perimeter), a nitrocellulose membrane was placed on the instrument table and an additional membrane near the wound. During four operations, particle counting was performed to detect particles > or =0.5 microm. Mean bacterial sedimentation on the nitrocellulose membrane on the instrument table was 2730 cfu/m(2)/h under standard ventilation conditions, whereas it decreased significantly to a mean of 305 cfu/m(2)/h when the LAF unit was used, i.e. within the suggested limit for ultraclean operating theatres (P=0.0001). The membrane near the wound showed a bacterial sedimentation of 4031 cfu/m(2)/h without the LAF unit and 1608 cfu/m(2)/h with the unit (P=0.0001). Particle counts also showed a reduction when the LAF unit was used. No significant difference was found at the four points in the operating theatre between samplings performed with, and without, the LAF unit. Use of a mobile LAF unit with turbulent air ventilation can reduce bacterial contamination at the surgical area in high-risk operations (e.g. prosthesis implant).

Abstract
Idiopathic retroperitoneal fibrosis (IRF) is a rare disease often causing obstructive uropathy. We evaluated the clinicopathologic features of 24 patients with IRF to characterize the histopathology of the disease and to provide a framework for the differential diagnosis with other retroperitoneal fibrosing conditions. Retroperitoneal specimens were analyzed by light and electron microscopy and by immunohistochemistry. Most patients presented with abdominal/lumbar pain, constitutional symptoms, and high acute-phase reactants. Overall, 20 had ureteral involvement and 13 developed acute renal failure. The retroperitoneal tissue consisted of a fibrous component and a chronic inflammatory infiltrate with the former characterized by myofibroblasts within a type-I collagen matrix. The infiltrate displayed perivascular and diffuse patterns containing lymphocytes, macrophages, plasma cells, and eosinophils. The perivascular aggregates had a central core of CD20(+) cells and a mantle of CD3(+) cells in equal proportions. In the areas of diffuse infiltrate, CD3(+) cells outnumbered the CD20(+) cells. Most plasma cells were positive for the IgG4 isotype. Small vessel vasculitis was found in the specimens of 11 patients. Our study indicates that a sclerotic background with myofibroblasts associated with a diffuse and perivascular infiltrate mainly consisting of T and B lymphocytes may be a pathological hallmark of IRF.

Abstract
INTRODUCTION Two opposing views of the human body have existed since time began. Can it be traded or does its value go beyond a monetary one? Today it is illegal to sell organs but the success of organ transplantation has give rise to an enormous controversy. The continued increase in the need for organs has lead to a major use of live donors. Consequently, clandestine selling of organs is becoming more widespread for two main reasons: scientific progress and market demand. Our aim was to consider the protection of ethical principles through legislation. MATERIALS AND METHODS Based on the principle that it is morally unacceptable for people to die on a waiting list, we analysed various ways in which the National Health Service could give incentives to live donors, including reimbursement of health expenses, tax relief, pension or early retirement benefits, or education grants for the children. Possible incentives for cadaveric organ donation included reimbursal of health and funeral costs, or increase in widow/er's pension. CONCLUSION The tendency may be toward reimbursement of costs rather than actual payments. A legal, ethical organ market could save thousands of human lives, but it must be correctly regulated.

Abstract
BACKGROUND Infections are one of the main complications that cause high morbidity and mortality in transplant recipients. This study sought to estimate the incidence of infections and their main determinants in liver transplant recipients in the first year after transplantation. PATIENTS AND METHODS A prospective study was conducted on 103 consecutive patients (72% men) who underwent transplantation in three centers in Northern (Bologna) and Central (Rome) Italy in 2005. Person-years (PY) at risk, incidence rates (IR), IR ratios and 95% confidence intervals were computed for viral, fungal, and bacterial infections. RESULTS The 103 patients (median age 55 years) contributed a total of 78.2 PYs, with a median follow-up of 286 days (interquartile range: 194 to 365 days). Fifty-eight patients (56.3%) experienced one or more infections, namely, 151 events (IR = 193.2 infections/100 PYs). IR for bacterial, fungal, and viral infections were 110.0, 56.3, and 26.9 infections/100 Pys, respectively. Within the first 30 days after transplantation, 37.9% patients (39/103) developed one or more events. Bacterial infections represented the most frequent event (86/151, 57.0%). Risk factors significantly associated with increased IR were gender (female), age (>50 years), prolonged intensive care stay volume of blood transfused during surgery and posttransplant, and need for retransplantation. CONCLUSIONS These preliminary results showed the relevance of infectious events after liver transplantation especially those of bacterial etiology, and identified factors mainly associated with their occurrence.

Abstract
OBJECTIVE Methotrexate (MTX) represents the antirheumatic drug mainly used in rheumatoid arthritis (RA). HLA-G antigens are inducible nonclassical major histocompatibility complex class Ib molecules important for maintaining anti-inflammatory conditions. The HLA-G gene is characterized by a deletion/insertion polymorphism of 14 bp that controls specific mRNA stability and protein levels. It has been reported that MTX therapy mediates an increase of interleukin-10-producing cells. This cytokine up-regulates HLA-G expression. For this, we tested the hypothesis of an MTX-mediated HLA-G production and the possible relationship with the HLA-G 14-bp polymorphism. METHODS Peripheral blood mononuclear cells from healthy individuals and non-MTX-treated RA patients were activated with different MTX concentrations, and soluble HLA-G (sHLA-G) and interleukin-10 production was investigated by specific immunoenzymatic assay. HLA-G 14-bp polymorphism genotyping was performed in healthy individuals and RA patients, defined as 'responders' and 'nonresponders' to the MTX therapy. RESULTS MTX activation induces the production of sHLA-G molecules. A significant association was observed between the highest sHLA-G1 concentrations and the -14/-14 bp genotype. The analysis of the HLA-G 14-bp polymorphism in MTX-treated RA patients has confirmed an increase of the -14/-14 bp genotype in the responder group (chi=6.12, P=0.02; chi test) (odds ratio=2.46 (95% confidence interval, 1.26-4.84) P=0.009; logistic regression model). CONCLUSION Our results propose that the MTX induces the production of the anti-inflammatory sHLA-G molecules that concur with the therapy response. Furthermore, the association between -14/-14 bp genotype and MTX clinical outcome proposes this polymorphism as a therapy marker in the early phases of the disease.

Abstract
PURPOSE Early breast cancer presents with a remarkable heterogeneity of outcomes. Undetected, microscopic lymph node tumor deposits may account for a significant fraction of this prognostic diversity. Thus, we systematically evaluated the presence of lymph node tumor cell deposits<or=0.2 mm in diameter [pN0(i+), nanometastases] and analyzed their prognostic effect. EXPERIMENTAL DESIGN Single-institution, consecutive patients with 8 years of median follow-up (n=702) were studied. To maximize chances of detecting micrometastases and nanometastases, whole-axilla dissections were analyzed. pN0 cases (n=377) were systematically reevaluated by lymph node (n=6676) step-sectioning and anticytokeratin immunohistochemical analysis. The risk of first adverse events and of distant relapse of bona fide pN0 patients was compared with that of pN0(i+), pN1mi, and pN1 cases. RESULTS Minimal lymph node deposits were revealed in 13% of pN0 patients. The hazard ratio for all adverse events of pN0(i+) versus pN0(i-) was 2.51 (P=0.00019). Hazards of pN1mi and pN0(i+) cases were not significantly different. A multivariate Cox model showed a hazard ratio of 2.16 for grouped pN0(i+)/pN1mi versus pN0(i-) (P=0.0005). Crude cumulative incidence curves for metastatic relapse were also significantly different (Gray's test chi2=5.54, P=0.019). CONCLUSION Nanometastases are a strong risk factor for disease-free survival and for metastatic relapse. These findings support the inclusion of procedures for nanometastasis detection in tumor-node-metastasis staging.

Abstract
We enrolled all 2162 in situ and 21 148 invasive cases of breast cancer in 17 areas of Italy, diagnosed in 1997–2001. Rates of early cancer increased by 13.7% in the screening age group (50–69 years), and breast conserving surgery by 24.6%. Advanced cancer rates decreased by 19.4%, and mastectomy rates by 24.2%. Service screening did not increase mastectomy rates in the study population.

Abstract
BACKGROUND In recent years, several cases of mandibular necrosis associated with long-term use of bisphosphonates have been reported. The estimated incidence varies from 1% to 4.6%. PATIENTS AND METHODS We conducted an observational study with the aim of determining the incidence of jaw osteonecrosis in advanced breast cancer patients with bone metastases under bisphosphonate treatment and to identify subjects at higher risk of developing this complication evaluating preclinical signs. We considered two groups of patients. All the patients complaining of odontostomatological symptoms underwent maxillary CT scan and maxillo-surgeon clinical examination. Asymptomatic patients were asked to perform a standard orthopantomography (OPT). RESULTS From February 2005 to October 2005, we observed five patients with jaw bone necrosis (6%). Diagnosis was radiological and clinical. In two patients a confirmatory biopsy was performed. In the same time interval, OPTs were collected from 76 asymptomatic patients. Three OPTs revealed radiological features of suspicious mandibular necrosis. Maxillary CT scan confirmed the presence of an osteolityc area with signs of periosteal reaction. All the three patients were referred to maxillo-surgeon and two out of three patients underwent mandibular biopsy, but histopathological results were not conclusive. CONCLUSIONS In our experience, the incidence of jaw bone necrosis in breast cancer patients seems to be higher than in other reports (6%). Radiological features of suspicious jaw necrosis were observed in three asymptomatic patients. We do not know how these findings should be considered. Anyway, standard OPT is a simple procedure, and may allow identification of periodontal conditions that in some way can predispose to the development of this uncommon event.

Abstract
PURPOSE Recent small-sized genomic studies on the identification of breast cancer bioprofiles have led to profoundly dishomogenous results. Thus, we sought to identify distinct tumor profiles with possible clinical relevance based on clusters of immunohistochemical molecular markers measured on a large, single institution, case series. EXPERIMENTAL DESIGN Tumor biological profiles were explored on 633 archival tissue samples analyzed by immunohistochemistry. Five validated markers were considered, i.e., estrogen receptors (ER), progesterone receptors (PR), Ki-67/MIB1 as a proliferation marker, HER2/NEU, and p53 in their original scale of measurement. The results obtained were analyzed by three different clustering algorithms. Four different indices were then used to select the different profiles (number of clusters). RESULTS The best classification was obtained creating four clusters. Notably, three clusters were identified according to low, intermediate, and high ER/PR levels. A further subdivision in two biologically distinct subtypes was determined by the presence/absence of HER2/NEU and of p53. As expected, the cluster with high ER/PR levels was characterized by a much better prognosis and response to hormone therapy compared to that with the lowest ER/PR values. Notably, the cluster characterized by high HER2/NEU levels showed intermediate prognosis, but a rather poor response to hormone therapy. CONCLUSIONS Our results show the possibility of profiling breast cancers by means of traditional markers, and have novel clinical implications on the definition of the prognosis of cancer patients. These findings support the existence of a tumor subtype that responds poorly to hormone therapy, characterized by HER2/NEU overexpression.

Abstract
INTRODUCTION Excess of incidence rates is the expected consequence of service screening. The aim of this paper is to estimate the quota attributable to overdiagnosis in the breast cancer screening programmes in Northern and Central Italy. METHODS All patients with breast cancer diagnosed between 50 and 74 years who were resident in screening areas in the six years before and five years after the start of the screening programme were included. We calculated a corrected-for-lead-time number of observed cases for each calendar year. The number of observed incident cases was reduced by the number of screen-detected cases in that year and incremented by the estimated number of screen-detected cases that would have arisen clinically in that year. RESULTS In total we included 13,519 and 13,999 breast cancer cases diagnosed in the pre-screening and screening years, respectively. In total, the excess ratio of observed to predicted in situ and invasive cases was 36.2%. After correction for lead time the excess ratio was 4.6% (95% confidence interval 2 to 7%) and for invasive cases only it was 3.2% (95% confidence interval 1 to 6%). CONCLUSION The remaining excess of cancers after individual correction for lead time was lower than 5%.

Abstract
OBJECTIVE Cerebral blood flow tests have increasingly been advocated for the confirmation of brain death (BD). Four-vessel angiography has been considered the most reliable investigation in the diagnosis of BD for >30 yrs, but it is invasive. (99m)Tc-HMPAO SPECT provides noninvasive, multiplanar imaging of brain tissue perfusion. The aim of this study was to check the reliability of SPECT compared with contrast angiography. DESIGN Prospective, blind study. SETTING Neurointensive care unit of a university hospital. PATIENTS Consecutive clinically brain dead patients with flat electroencephalogram. INTERVENTIONS BD was diagnosed according to Italian law. (99m)Tc-HMPAO SPECT and four-vessel angiography were performed in the same session; the rater of each investigation ignored the results of the other. Blood pressure, Sp(O2), and P(ECO2) were monitored throughout the study: any episode of hypoxia or hypotension caused exclusion of the patient from the study. MEASUREMENTS AND MAIN RESULTS Twenty brain dead patients were enrolled. The cause of BD was head injury in seven cases (35%), subarachnoid hemorrhage in seven (30%), spontaneous hemorrhage in one (10%), brain tumors in two (10%), stroke in two (10%), and thrombosis of the sagittal sinus in one (5%). Both angiography and SPECT confirmed BD in 19 of 20 patients: angiography showed the absence of filling of intracranial arteries, while SPECT showed a picture of "empty skull." For the remaining patient, angiography showed slight and late filling of left vertebral, basilar, and posterior cerebral arteries, while SPECT showed faint traces of uptake in the posterior fossa on the right side and on the midline. For this patient, the tests were repeated 48 hrs later, and both showed the arrest of intracranial circulation, thus confirming BD. CONCLUSIONS Our results confirm the reliability of SPECT in the diagnosis of BD; because SPECT is noninvasive, it is a good candidate for the "gold standard" of diagnosis.

Abstract
Hepatitis B virus (HBV) is a serious cause of morbidity and mortality in hepatitis B surface (HBsAg) antigen-positive patients treated with chemotherapy. Because the hepatitis is related to HBV virological reactivation, application of effective antiviral therapy, such as Lamivudine, has been attempted. Despite the use of these antiviral agents at the time of clinical hepatitis, some HBsAg-positive patients still develop hepatic failure and die. We used the Molecular Adsorbent Recirculating System (MARS) (MARS Monitor; Teraklin AG, Rostock, Germany) to treat 5 HBsAg-positive lymphoma patients with acute hepatic failure due to chemotherapy despite lamivudine treatment. Before and after each treatment we monitored the parameters of neurological status (EEG, cerebral CT and Glasgow coma score), hemodynamic parameters, acid-base equilibrium and blood gases as well as hepatic and renal function. The inclusion criteria were these of the King's College Hospital. Statistical analysis by Student t method showed significant results (P < .01). Three of 5 patients are alive without signs of reactivation of viral or hematological diseases at 1 year follow-up. The 2 patients died because MARS treatment was started too late, with Glascow coma score grade IV, hemodynamic instability, and mechanical ventilator assistance. Despite the limited number of cases, we believe that MARS can be applied to patients with a high tolerance and yield good results, but the treatment has to start at the first signs of hepatic failure.

Abstract
The effect of mammography screening programmes on the incidence of in situ breast cancer (CIS) is described by analysis of the CIS incidence trend in the 1990s and comparison of pre-screening and screening periods in six areas of Italy. All 1069 CIS arising in women aged 40-79 years between 1988 and 1999 were analysed through age-standardised rates and Poisson regression models. The results show that, for the whole series, ductal carcinoma in situ (DCIS) represented 89% and lobular carcinoma in situ (LCIS) 11% of CIS detected. For all six areas, the introduction of screening increased the incidence of DCIS (screening/pre-screening ratio, range 1.12-1.77). Overall, DCIS represented 11% (226/2022) of all screening-detected cancers. A significant increasing trend in DCIS incidence during the 1990s and a modification in pattern of age-specific incidence rates after the beginning of screening programmes were observed. This increase can largely be explained by screening programmes. The incidence observed during the screening period was a persistent 39% higher than during the pre-screening period, after adjustment for the "percentage of cases diagnosed by screening". The increase also involves women at an age not targeted by screening programmes. In conclusion, as the increasing trend in DCIS is not completely explained by the effect of the screening programmes, this supports the use of mammography as a "spontaneous" preventive practice during ongoing organised screening programmes, particularly among age groups not usually invited for screening. Therefore, the effect of mammography on stage-specific incidence of CIS may be more marked than expected on the basis of the effect of screening programmes.

Abstract
BACKGROUND HLA-G, a human nonclassic MHC class I molecule, is responsible for complex immunoinhibitory functions. HLA-G is expressed as membrane-bound and is secreted as soluble molecules by the peripheral blood CD14+ monocytes activated by IL-10. OBJECTIVE It has been reported that LPS stimulation induces IL-10 production by PBMCs and that IL-10 levels are reduced in patients with severe asthma compared with patients with mild asthma and healthy subjects. The study was designed to investigate whether this impaired IL-10 production can affect the expression and the secretion of soluble HLA-G (sHLA-G)-1/HLA-G5 molecules. METHODS We investigated the production of sHLA-G1/HLA-G5 and IL-10 by specific ELISAs in the culture supernatants of LPS-activated PBMCs from 24 healthy subjects and 20 patients with moderate to severe persistent asthma. RESULTS LPS stimulation induced the secretion of IL-10 and sHLA-G1/HLA-G5 molecules in all healthy subjects, whereas in patients with asthma, the levels of IL-10 were significantly lower (P < .001) and the number of cultures exhibiting detectable sHLA-G1/HLA-G5 was reduced (7/20; P < .001). The addition of exogenous IL-10 to LPS-stimulated PBMCs from patients with asthma restored normal sHLA-G1/HLA-G5 production. CONCLUSION Our data suggest that a specific deficit of IL-10 secretion in patients with asthma could prevent the normal production of sHLA-G1/HLA-G5 molecules. The reduction of immunosuppressive activity mediated by HLA-G could in turn contribute to the persistence of chronic airway inflammation in asthma.

Abstract
Screen-detected (SD) breast cancers are smaller and biologically more indolent than clinically presenting cancers. An often debated question is: if left undiagnosed during their preclinical phase, would they become more aggressive or would they only increase in size? This study considered a registry-based series (1988-1999) of 3329 unifocal, pT1a-pT3 breast cancer cases aged 50-70 years, of which 994 were SD cases and 2335 clinical cases. The rationale was that (1) the average risk of lymph node involvement (N+) is lower for SD cases, (2) nodal status is the product of biological aggressiveness and chronological age of the disease, (3) for any breast cancer, tumour size is an indicator of chronological age, and (4) for SD cases, tumour size is specifically an indicator of the duration of the preclinical phase, that is, an inverse indicator of lead time. The hypothesis was that the relative protection of SD cases from the risk of N+ and, thus, their relative biological indolence decrease with increasing tumour size. The odds ratio (OR) estimate of the risk of N+ was obtained from a multiple logistic regression model that included terms for detection modality, tumour size category, patient age, histological type, and number of lymph nodes recovered. A term for the detection modality-by-tumour size category interaction was entered, and the OR for the main effect of detection by screening vs clinical diagnosis was calculated. This increased linearly from 0.05 (95% confidence interval: 0.01-0.39) in the 2-7 mm size category to 0.95 (0.64-1.40) in the 18-22 mm category. This trend is compatible with the view that biological aggressiveness of breast cancer increases during the preclinical phase.

Abstract
To evaluate incidence rates (IRs) of classic Kaposi's sarcoma (CKS) in Italy after the spread of AIDS, we distinguished CKS from AIDS-related KS (AKS) using an 'ad hoc' record linkage procedure between 15 Cancer Registries (CRs) (21% of the Italian population) and the national AIDS Registry. Between 1985 and 1998, 874 cases of CKS and 634 cases of AKS were diagnosed in the study areas. CKS accounted for 16 and 27% of KS cases below 55 years of age in men and women, respectively, but for 91 and 100% of those above age 55. The IRs for CKS were 1.0/ in men and 0.4/100,000 in women, but they varied between 0.3 in Umbria and 4.7 in Sassari in men, and between 0.1 in Parma and 1.7 in Sassari in women. IRs of CKS in both genders were stable between 1985-1987 and 1993-1998. In Northern and Central CRs the IR (adjusted for age and gender) for CKS was 0.5 in individuals born in the same area, but 1.6 in individuals born in Southern Italy or in the Islands (rate ratio = 3.2) suggesting that KS-associated herpesvirus, the cause of KS, is acquired early in life.

Abstract
The combination of lamivudine and hepatitis B immunoglobulins (HBIg) to prevent recurrence of HBV hepatitis has significantly improved the survival of patients transplanted for HBV-related end-stage liver disease. Generally, HBIg are administered intravenously. We evaluated the efficacy, tolerability, and cost savings of long-term intramuscular HBIg and lamivudine in 28 patients (23 men and 5 women), who received liver transplants for acute or chronic HBV-related liver disease. Twelve patients started lamivudine before and 16 at the time of liver transplantation. HBIg were administered intravenously during the first week (50 to 70,000 IU) and intramuscularly thereafter (1200 IU every 3 to 6 weeks) to maintain an HbsAb titer >100 IU/L. Mean follow-up was 20 +/- 13 months. Only one patient experienced HBV recurrence (9 months after transplantation). This patient had failed to follow the scheduled prophylaxis. Cumulative survival at 3 years was 83%. Intramuscular HBIg were well tolerated in all cases. Cost analysis comparing intramuscular vs intravenous HBIg administration showed that 39,490 Euros were saved per patient per year. These preliminary results show that low-dose intramuscular HBIg and lamivudine are efficacious and cost-effective for long-term prophylaxis of hepatitis B recurrence after liver transplantation.

Abstract
PURPOSE The microtubule-stabilizing agent patupilone (epothilone B, EPO906) and the tyrosine kinase inhibitor imatinib (STI571, Glivec) which primarily inhibits Bcr-Abl, PDGF and c-Kit tyrosine kinase receptors, were combined in vivo to determine if any interaction would occur with respect to antitumour effect and tolerability using rat C6 glioma xenografted into nude mice. METHODS Patupilone and imatinib were administered alone or in combination at suboptimal doses. Imatinib treatment (orally once daily) was initiated 4 days after s.c. injection of rat C6 glioma cells into athymic nude mice and patupilone administration (i.v. once per week) was started 3 or 4 days after imatinib treatment. RESULTS As a single agent, imatinib was inactive in the regimens selected (100 mg/kg: T/C 86% and 116%; 200 mg/kg: T/C 68% and 84%; two independent experiments), but well tolerated (gain in body weight and no mortalities). Patupilone weekly monotherapy demonstrated dose-dependent antitumour effects (1 mg/kg: T/C 67% and 70%; 2 mg/kg: T/C 32% and 63%; 4 mg/kg: T/C 3% and 46%). As expected, dose-dependent body weight losses occurred (final body weight changes at 1 mg/kg were -7% and -3%; at 2 mg/kg were -23% and -13%; and at 4 mg/kg were -33% and -15%). Combining 2 mg/kg patupilone and 200 mg/kg per day imatinib in one experiment produced a non-statistically significant trend for an improved antitumour effect over patupilone alone (combination, T/C 9%), while in the second experiment, enhancement was seen with the combination and reached statistical significance versus patupilone alone (combination, T/C 22%; P=0.008). Reduction of the imatinib dose to 100 mg/kg per day resulted in no enhancement of antitumour activity in combination with 2 mg/kg patupilone. Reduction of the patupilone dose to 1 mg/kg resulted in a reduced antitumour effect, and only a trend for synergy with either imatinib dose (combination, T/C 46% and 40%). Pooling the data from the two experiments confirmed a significant synergy for the combination of 2 mg/kg patupilone and 200 mg/kg per day imatinib (P=0.032), and a trend for synergy at the 1 mg/kg patupilone dose. Reduction in the imatinib dose to 100 mg/kg per day resulted only in additivity with either dose of patupilone. Body weight losses were dominated by the effect of patupilone, since no greater body weight loss was observed in the combination groups. CONCLUSION Combining patupilone with high-dose imatinib produced an increased antitumour effect without affecting the tolerability of treatment in a relatively chemoresistant rat C6 glioma model. Such results indicate that further evaluation is warranted, in particular to elucidate possible mechanisms of combined action.

Abstract
The objective of this study was to analyse incidence and mortality cancer trends in the Italian Network of Cancer Registries (about 8,000,000 inhabitants) during the period 1986-1997. Included were 525,645 newly diagnosed cancers and 269,902 cancer deaths (subjects > 14 years). Joinpoints (points in time where trend significantly changes from linearity) were found and estimated annual percentage changes (EAPC) used to summarize tendencies. Overall cancer incidence increased in both sexes and cancer mortality significantly decreased (since 1991 among men). Lung cancer showed significantly decreasing incidence (EAPC = -1.4%) and mortality (EAPC = -1.6%) among men and increasing trends among women. In women, breast cancer incidence significantly increased (EAPC= +1.7%) and mortality decreased since 1989 (EAPC= -2.0%). Stomach cancer incidence and mortality decreased in both sexes. Prostate incidence sharply increased since 1991 and mortality decreased. Colon cancer incidence increased and rectum mortality decreased significantly in both sexes. Significant increases in incidence were also found for kidney (up to 1991 among men), urinary bladder, skin epithelioma, melanoma, liver (up to 1993 among men), pancreas, mesothelioma, Kaposi's sarcoma (up to 1995 among men), testis, thyroid, non-Hodgkin's lymphomas and multiple myeloma. Mortality significantly decreased for cancers of the oral cavity and pharynx, oesophagus, liver (women), larynx (men), bone, cervix (since 1990), central nervous system, urinary bladder, thyroid, Hodgkin's lymphomas and leukaemias (men). Non-Hodgkin's lymphoma mortality increased in both sexes. In conclusion, most of the changes seen can be explained as the effect of changes in smoking habits and of the extension of secondary prevention activities. The Italian health care system will also have to cope with growing cancer diagnostic and therapeutic needs due to population ageing.

Abstract
In the present study, time trends of the main quality indices in the pool of the Italian Network of Cancer Registries (pool AIRT) are presented for the period 1986-1997. The percentage of cases with morphological verification increased from 75% to 83% among males and from 77% to 85% among females. Cases known only from death certificates (DCO) decreased over time in both sexes; in recent years they were about 3% of the whole case-series. Mortality incidence ratio decreased over time, from 66% to 54% among males and from 55% to 48% among females. Also cases with unknown primary site showed a decreasing time tendency. Such quality indices are also presented for specific cancer sites and for elderly subjects (75+ years). The overall trends of quality indices showed an improvement in both the activity of Cancer Registries and of the Health System.

Abstract
In this paper temporal trend of the upper gastrointestinal tract cancers in the Italian Network of Cancer Registries (pool AIRT) are analysed during the period 1986-1997. Oesophagus cancer (4477 cases and 4226 deaths analysed) showed a decrease in incidence rates that was statistically significant among males and less evident in recent years among females. Mortality is significantly decreasing both among males (since 1993) and females. Stomach cancer (34282 cases and 26430 deaths) had a stable decreasing trend, in both sexes, for both incidence which decreased at a rate of more 3% every year, and of mortality, mean annual rate decrease over 4%. As regards liver cancer (13893 cases 13655 deaths) an increasing incidence trend (up to 1993 among males) has been documented; mortality was stable. Cancers of the biliary tract (6662 cases and 5065 deaths) showed stable rates both in incidence (slightly decreasing among females) than in mortality. Pancreas cancer (13300 cases and 12937 deaths) presented increasing incidence in both sexes with stable mortality rates.

Abstract
Retroperitoneal fibrosis is an uncommon disease, characterized by the replacement of normal retroperitoneal tissue with fibrosis and/or chronic inflammation. In two thirds of the cases retroperitoneal fibrosis is idiopathic (IRF), whereas in the remaining ones it is secondary/associated to cancer, infections, drugs, autoimmune disease and vasculitis. IRF appears as a dense, fibrous plaque that usually arises between the level of the lower aorta and the common iliac arteries. As the plaque progresses, it engulfs the adjacent structures (e. g., ureters). In its early stages IRF is characterized by a rich infiltrate of lymphocytes, plasma cells and macrophages interspersed within fibroblasts and collagen bundles. In its advanced stages it becomes relatively avascular and acellular with abundant collagen bundles and scattered calcifications. The pathogenesis is unknown: some Authors suggest that IRF is a consequence of a local autoimmune reaction against atherosclerotic plaque antigens whereas others propose that it is the manifestation of a systemic autoimmune disease. The presenting signs and symptoms are non-specific; systemic manifestations (fever, anorexia, weight loss), often associated with local symptoms, are usually found to be related to the entrapment of retroperitoneal structures. The most common local symptom is lumbar and/or abdominal pain. The treatment can be surgical and/or medical: the former is required when obstructive complications are present; the latter, associated or not with surgery, can significantly improve the outcome of IRF patients and usually modifies the natural history of the disease. Steroids and tamoxifen are the most used drugs, whereas other agents such as azathioprine, methotrexate and cyclosporine are usually given to non-responder patients.

Abstract
We present a new device, SPARC Sling System, designed for the placement of a pubo-urethral sling for the correction of female stress urinary incontinence due to urethral hypermobility. Twenty patients (medium age 53.4), affected by SUI resulting from urethral hypermobility (range of Q-tip test 30°-70°, VLPP > of 70 cmH2O and POP grade < II according to Baden and Walker classification) are underwent to this surgical procedure. 85% of them, after a medium follow-up of 10.5 months (range 3–21) show a complete correction of SUI. Three patients, in which SUI persists, refer a significant improvement of the incontinence. We think that the high rate of success (85%), the swiftness of the execution and the versatility of the SPARC Sling System put this surgical procedure between the mini-invasive selected methods to correct female stress urinary incontinence due to urethral hypermobility.

Abstract
A record linkage was carried out between the Italian National Registry of AIDS and 19 cancer registries. The aim was to evaluate the 1986 through 1998 trends in incidence rate (IR) of AIDS-defining cancers (ADCs) among persons with AIDS (PWA) in Italy overall and according to various characteristics. A steady decrease in IRs was found for Kaposi sarcoma (KS) in men between 1986-1992 (2.5 per 100 person-years [py]) and 1997-1998 (1.0 per 100 py). Conversely, the first decrease in IRs of KS in women (from 0.9 to 0.6 per 100 py) and of non-Hodgkin lymphoma in both genders (from 1.7 to 0.7 per 100 py) was seen between 1993-1996 and 1997-1998, thus pointing to a favorable impact of highly active antiretroviral therapies. The decline was consistent across different age and HIV transmission groups, but it was more marked in PWA with a CD4 count >50 cells/microL than in PWA with more severe immune suppression. As a proportion of AIDS cases, invasive cervical cancer increased from 1.5% in 1993-1996 to 2.4% in 1997-1998, but IRs after AIDS could not be evaluated. On account of the marked decline of KS in men in 1997-1998, the overall burden of ADCs in Italy became similar in both genders.
