Prognosis of screen-detected breast cancers: results of a population based study
BACKGROUND: The reduced mortality rate from breast carcinoma among women offered screening mammography is demonstrated after 15–20 years of follow-up. However, the assessment of 5-year overall and event-free survival could represent an earlier measure of the efficacy of mammography screening program (MSP). METHODS: All cases of breast cancer diagnosed in the Province of Modena between years 1996 and 2000 in women aged 50 to 69 years, were identified through the Modena Cancer Registry (MCR). Stage of disease and treatment information were obtained from clinical records. All the events occurring up to June 30, 2003 were retrieved by experienced monitors. Five-year overall and event-free survival were the principal end-points of the study. RESULTS: During a 5-year period, 587 primary breast cancers were detected by the MSP and 471 primary breast cancers were diagnosed out of the MSP. The screen-detected breast cancers were smaller, more likely node negative, with low histological grade, low proliferative activity and positive receptors status. Furthermore, the breast cancer diagnosed through the MSP more frequently received a conservative surgery. The 5-year survival rate was 94% in the screen-detected group, versus 84% in the other group (p = 0.0001). The rate of 5-year event-free survival was 89% and 75% for the MSP participants and not participants, respectively (p = 0.0001). CONCLUSIONS: Our data confirm a favourable outcome of screen-detected breast cancers in terms of five-year overall and event-free survival, which reflect the good quality assurance parameters of the MSP. Finally, a cancer registry should be implemented in every area covered by screening programs

Lack of privileged access to awareness for rewarding social scenes in Autism Spectrum Disorder
Reduced social motivation is hypothesised to underlie social behavioural symptoms of Autism Spectrum Disorder (ASD). The extent to which rewarding social stimuli are granted privileged access to awareness in ASD is currently unknown. We use continuous flash suppression to investigate whether individuals with and without ASD show privileged access to awareness for social over nonsocial rewarding scenes that are closely matched for stimulus features. Strong evidence for a privileged access to awareness for rewarding social over nonsocial scenes was observed in neurotypical adults. No such privileged access was seen in ASD individuals, and moderate support for the null model was noted. These results suggest that the purported deficits in social motivation in ASD may extend to early processing mechanisms

Post-operative arm morbidity and quality of life. Results of the ALMANAC randomised trial comparing sentinel node biopsy with standard axillary treatment in the management of patients with early breast cancer
This study is the first large prospective RCT of sentinel node biopsy (SNB) compared with standard axillary treatment (level I-III axillary lymph node dissection or four node sampling), which includes comprehensive and repeated quality of life (QOL) assessments over 18 months. Patients (n = 829) completed the Functional Assessment of Cancer Therapy - Breast (FACT-B+4) and the Spielberger State/Trait Anxiety Inventory (STAI) at baseline (pre-surgery) and at 1, 3, 6, 12, and 18 months post-surgery. There were significant differences between treatment groups favouring the SNB group throughout the 18 months assessment. Patients in the standard treatment group showed a greater decline in Trial Outcome Index (TOI) scores (physical well-being, functional well-being and breast cancer concerns subscales in FACT-B+4) and recovered more slowly than patients in the SNB group (p 0.05). For 6 months post-surgery younger patients reported less favourable QOL scores (p < 0.001) and greater levels of anxiety (p < 0.01). In view of the benefits regarding arm functioning and quality of life, the data from this randomised study support the use of SNB in patients with clinically node negative breast cancer
