We assessed the prognostic value of minimal residual disease (MRD) within the ML17638 phase 3 trial from the Fondazione Italiana Linfomi, investigating the role of rituximab maintenance in elderly follicular lymphoma (FL) patients after a brief first-line chemoimmunotherapy. MRD for the bcl-2/IgH translocation was determined on bonemarrowcells in a centralized laboratory belonging to the Euro-MRD consortium, using qualitative and quantitative polymerase chain reactions (PCRs). Of 234 enrolled patients, 227 (97%) were screened at diagnosis. A molecular marker (MM) was found in 51%. Patients with an MM were monitored at 8 subsequent times. Of the 675 expected follow-up samples, 83% were analyzed. Conversion to PCR negativity predicted better progression-free survival (PFS) at all post-treatment times (eg, end of therapy: 3-year PFS, 72% vs 39%; P < .007). MRD was predictive in both maintenance (83% vs 60%; P < .007) and observation (71% vs 50%; P < .001) groups. PCR positivity at the end of induction was an independent adverse predictor (hazard ratio, 3.1; 95% confidence interval, 1.36-7.07). MRD is a powerful independent outcome predictor in FL patients who receive rituximab-intensive programs, suggesting a need to investigate its value for decision-making.

We investigated the association between diet and head and neck cancer (HNC) risk using data from the International Head and Neck Cancer Epidemiology (INHANCE) consortium. The INHANCE pooled data included 22 case-control studies with 14,520 cases and 22,737 controls. Center-specific quartiles among the controls were used for food groups, and frequencies per week were used for single food items. A dietary pattern score combining high fruit and vegetable intake and low red meat intake was created. Odds ratios (OR) and 95% confidence intervals (CI) for the dietary items on the risk of HNC were estimated with a two-stage random-effects logistic regression model. An inverse association was observed for higher-frequency intake of fruit (4th vs. 1st quartile OR = 0.52, 95% CI = 0.43-0.62, p trend < 0.01) and vegetables (OR = 0.66, 95% CI = 0.49-0.90, p trend = 0.01). Intake of red meat (OR = 1.40, 95% CI = 1.13-1.74, p trend = 0.13) and processed meat (OR = 1.37, 95% CI = 1.14-1.65, p trend < 0.01) was positively associated with HNC risk. Higher dietary pattern scores, reflecting high fruit/vegetable and low red meat intake, were associated with reduced HNC risk (per score increment OR = 0.90, 95% CI = 0.84-0.97). © 2011 Springer Science+Business Media B.V.

BACKGROUND: Although treatment for multiple myeloma (MM) has considerably improved in the past decade, MM continues to be an incurable hematological malignancy that causes most patients to eventually relapse and die from their illness. Thus, the identification of effective salvage strategies remains a priority. METHODS: In this trial, the authors evaluated the safety and efficacy of bortezomib and dexamethasone [V: on days 1 and 15 (1.3 mg/mq); D: on days 1-2 and 15-16, every 28-day cycle until progression (20 mg/d)] as maintenance therapy (MT) in patients with advanced MM who responded to salvage therapy that used a bortezomib-containing regimen. RESULTS: Forty-nine MM patients were enrolled in this study between October of 2004 and April of 2008. All patients who were included in this study were responsive to a prior salvage therapy with bortezomib and had a measurable disease. The bortezomib and dexamethasone MT improved the quality of responses to complete remission in 4 patients and very good partial response in 3 patients. In addition, 10 patients experienced at least a 50% improvement in their symptoms. The median time to progression (TTP) was 16 months with a progression-free survival of 61% after 1 year. The overall response after 1 year was 76%, and the cumulative incidence of death due to disease progression, which was adjusted for competitive risk events, was 14%. Non-dose-limiting toxicities included neuropathy (predominantly grade 1), herpes zoster reactivation, pneumonia, and gastrointestinal affections (constipation and diarrhea). Three patients developed grade 2 neuropathy, which required a bortezomib dose reduction to 1.0 mg/mq. No grade 3 or 4 toxicities were recorded. CONCLUSIONS: The use of bortezomib and dexamethasone as MT in advanced MM was effective and well tolerated. The twice-monthly bortezomib infusion appeared to reduce the incidence of grade 3 and 4 neuropathies in comparison to similar experiences in other settings.

Results Twelve countries contributed data from a total of 15 screening programmes, all from Europe except the United States of America and Japan. Among women aged 50-69 years, 7,176,050 screening tests and 5324 screen-detected DCIS were reported. From 21% to 93% of DCIS had a pre-operative diagnosis (PO); 67-90% of DCIS received breast conservation surgery (BCS), and in 41-100% of the cases this was followed by radiotherapy; 6.4-59% received sentinel lymph node biopsy (SLNB) only and 0.8-49% axillary dissection (ALND) with 0.6% (range by programmes 0-8.1%) being node positive. Among BCS patients 35% received SLNB only and 4.8% received ALND. Starting in 2006, PO and SLNB use increased while ALND remained stable. SLNB and ALND were associated with larger size and higher grade DCIS lesions.Conclusions Variation in DCIS management among screened women is wide and includes lymph node surgery beyond what is currently recommended. This indicates the presence of varying levels of overtreatment and the potential for its reduction.Background Ductal carcinoma in situ (DCIS) incidence has grown with the implementation of screening and its detection varies across International Cancer Screening Network (ICSN) countries. The aim of this survey is to describe the management of screen-detected DCIS in ICSN countries and to evaluate the potential for treatment related morbidity.Methods We sought screen-detected DCIS data from the ICSN countries identified during 2004-2008. We adopted standardised data collection forms and analysis and explored DCIS diagnosis and treatment processes ranging from pre-operative diagnosis to type of surgery and radiotherapy. © 2014 Elsevier Ltd.

In a controlled trial to evaluate the effectiveness of a simple educational and physical program administered to a large cohort of public servants, we previously found that 6 months following treatment the monthly frequency of headache and neck and shoulder pain and drug intake was reduced by 40% in the experimental compared with controls. These results were stable at a 12-month follow up. The program consists of brief shoulder and neck exercises to be performed several times a day, a relaxation exercise, and instructions on how to reduce parafunction and hyperfunction of the craniofacial and neck muscles during the day. The purpose of this work was to investigate whether the data previously obtained could be confirmed also in the group of 192 subjects that served as controls in first phase of the study and received the intervention in the second phase of the study. The primary endpoint was the change in frequency of headache and neck and shoulder pain expressed as the number of days per month with pain, and as the proportion of subjects with a ≥50% reduction of frequency (responder rate) at the last 2 months of the 6-month intervention period compared to the 2 months preceding the intervention (baseline). The number of days of analgesic drug consumption was also recorded. Days per month with headache at the baseline and at the end of intervention period were 6.40 and 4.58 (mean change -1.81, p < 0.0001), respectively; days with neck and shoulder pain were 7.48 and 6.18 (mean change -1.30, p = 0.0179); days of analgesic consumption were 1.67 and 1.17 (mean change -0.50, p = 0.0222). The responder rate was 42.3% for headache, 42% for neck and shoulder pain and 58.3% for drug consumption. In conclusion, this study adds further evidence on the efficacy of our program and its high acceptability in a large, unselected, working population. © 2010 Springer-Verlag.

Objective: Smokers are characterized by a low-grade systemic inflammatory state and an oxidant-antioxidant imbalance. Few human studies were conducted on the effects of resveratrol, a natural compound with anti-inflammatory and antioxidant properties, and no trial on smokers has been performed to date. We evaluated whether resveratrol has beneficial effects on markers of inflammation and oxidative stress in smokers. Methods and Results: A randomized, double- blind, cross-over trial was performed in 50 healthy adult smokers: 25 were randomly allocated to 'resveratrol-first' (30-days: 500mg resveratrol/day, 30-days wash-out, 30-days placebo) and 25 to 'placebo-first' (30-days placebo, 30-days wash-out, 30-days 500mg resveratrol/day). Resveratrol significantly reduced C-reactive protein (CRP) and triglyceride concentrations, and increased Total Antioxidant Status (TAS) values. After analyzing data with general linear models to assess period and carry-over effects, the ratios of the values after resveratrol to those after placebo were respectively: 0.47 (95%CI 0.38-0.59) -CRP- and 0.71 (95%CI 0.65-0.78) -triglycerides-, while TAS increased by 74.2 mol/L (95%CI 60.8-87.6). Uric acid, glucose, insulin, cholesterol, liver enzyme concentrations, and weight, waist circumference, and blood pressure values did not significantly change after resveratrol supplementation. Conclusions: Because resveratrol has anti-inflammatory, anti-oxidant, and hypotriglyceridemic effects, its supplementation may beneficially affect the increased cardiovascular risk of healthy smokers. © 2013 Bentham Science Publishers.

Blood stream infections (BSIs) remain one of the major causes of morbidity and mortality for patients receiving an allogeneic hematopoietic stem cell transplantation (HSCT). In the present study, we evaluated the incidence and characteristics of BSI within 1 year after allogeneic HSCT in 269 consecutive adult patients who received antibacterial prophylaxis with levofloxacin. Cumulative incidence of BSI was 12% (95% confidence interval, 8-16%). Bacteria were responsible for 30 out of the 32 BSI, while fungi were responsible for 2 episodes of BSI. The median onset of BSI was day 8 (range 1-328 days) post transplant, and 66% of BSI occurred before neutrophil recovery. Gram-positive organisms accounted for 60% (n=18) of bacteremia, and gram-negative isolates for 40% (n=12) of the cases. Coagulase-negative staphylococci were the most commonly isolated gram-positive pathogens (53% of the cases), while Escherichia coli was the most commonly isolated gram-negative bacteria (58% of the cases). Candida albicans and Candida guillermondii were isolated from patients with candidemia. Resistance to fluoroquinolones (FQ) was common with 13% of gram-positive isolates being susceptible to FQ, while 50% of the gram-negative rods were susceptible to FQ. Crude mortality and mortality attributable to BSI were both 3% (1 of 32). In conclusion, our data suggest that despite the emergence of antibiotic resistance, FQ prophylaxis may be considered an appealing approach in allogeneic HSCT recipients and is also worth evaluating in randomized studies. © 2011 John Wiley & Sons A/S.

The benefits of exercise and behavioural recommendations in gestational diabetes mellitus (GDM) are controversial. In a randomized trial with a 2×2 factorial design, we examined the effect of exercise and behavioural recommendations on metabolic variables, and maternal/neonatal outcomes in 200 GDM patients. All women were given the same diet: group D received dietary recommendations only; group E was advised to briskly walk 20-min/day; group B received behavioural dietary recommendations; group BE was prescribed the same as B+E. Dietary habits improved in all groups. In a multivariable regression model, fasting glucose did not change. Exercise, but not behavioural recommendations, was associated with the reduction of postprandial glucose (p<0001), glycated haemoglobin (HbA1c; p<0.001), triglycerides (p=0.02) and C-reactive protein (CRP; p<0.001) and reduced any maternal/neonatal complications (OR = 0.50; 95%CI=0.28-0.89;p=0.02). In GDM patients a simple exercise programme reduced maternal postprandial glucose, HbA1c, CRP, triglycerides and any maternal/neonatal complications, but not fasting glucose values. © 2014 John Wiley & Sons Ltd.

Malignant mesotheliomas are strictly related to asbestos, but in a proportion of cases no exposure can be recalled. Published estimates of this proportion have important variations. Historical and geographical differences in the fraction of cancer due to any given exposure are to be expected, but incomplete identification of non-occupational exposures may have played a role.To assess the role of non-occupational exposures in causing malignant mesotheliomas in Italy, the exposures of cases registered by the national mesothelioma registry (ReNaM) were examined. ReNaM started in 1993 in five regions and currently covers 98% of the Italian population. Information on occupational and non-occupational exposures of cases is collected whenever possible.From 1993 to 2001 ReNaM registered 5173 malignant mesothelioma cases, and exposures were assessed in 3552 of them. 144 and 150 cases with exposures limited to environmental (living in the neighbourhood of an industrial or natural source of asbestos) or familial (living with a person occupationally exposed to asbestos) circumstances, respectively, were identified, accounting for 8.3% of all cases.Geographical variations in the proportion of cases due to non-occupational exposures may be explained by the past distribution of asbestos-using industries.

This article reviews the evidence concerning well known risk factors for bladder cancer, including several occupational exposures and tobacco smoking, and the underlying mechanistic processes. Emphasis is put on recent developments in the field of molecular epidemiology, including the study of carcinogen-DNA adducts in exfoliated bladder cells, of carcinogen-hemoglobin adducts, and of the modulating role played by genetically-based metabolic polymorphisms such as N-acetyltransferase. A model for bladder carcinogenesis in humans is offered. It is postulated that metabolic polymorphism plays a modulating role over the formation of macromolecule adducts, particularly at low doses of exposure.
