A randomised trial of weekend and evening breast screening appointments.

Background: There is a need to research interventions that improve access to and convenience of breast cancer screening services.

Methods: We conducted a randomised trial comparing invitations to out-of-hours appointments with standard office hour appointments. Women who were to be invited for routine breast screening were randomised (3 : 1 : 1 : 1) to one of these screening invitations: standard office hour appointment, office hour appointment with the option to change to an out-of-hours appointment, weekday evening appointment, or weekend appointment.

Assessing individual breast cancer risk within the U.K. National Health Service Breast Screening Program: a new paradigm for cancer prevention.

The aim of this study is to determine breast cancer risk at mammographic screening episodes and integrate standard risk factors with mammographic density and genetic data to assess changing the screening interval based on risk and offer women at high risk preventive strategies. We report our experience of assessing breast cancer risk within the U.K.

Prevention of breast cancer in the context of a national breast screening programme.

Breast cancer is not only increasing in the west but also particularly rapidly in eastern countries where traditionally the incidence has been low. The rise in incidence is mainly related to changes in reproductive patterns and lifestyle. These trends could potentially be reversed by defining women at greatest risk and offering appropriate preventive measures.

Menopausal symptoms and bone health in women undertaking risk reducing bilateral salpingo-oophorectomy: significant bone health issues in those not taking HRT.

Background: Women at high ovarian cancer risk, especially those with mutations in BRCA1/BRCA2, are encouraged to undergo bilateral risk-reducing salpingo-oophorectomy (BRRSPO) prior to the natural menopause. The decision to use HRT to cover the period of oestrogen deprivation up to 50 years of age is difficult because of balancing the considerations of breast cancer risk, bone and cardiovascular health.

Methods: We reviewed by questionnaire 289 women after BRRSPO aged ≤48 years because of high ovarian cancer risk; 212 (73%) of women responded.

Comparsion of the properties of two antigen-induced guinea pig lymphokines.

The properties of macrophage migration inhibition factor (MIF) and mitogenic factor (MF) were compared using culture supernatants of antigen-stimulated lymph node cells from inbred guinea pigs. Gel filtration on Sephadex G-100 indicated molecular weights of about 60,000 and 25,000 for MIF and MF, respectively. The lymphokines also differed with respect to heat sensitivity, MIF being largely inactivated by 60 degrees C for 20 min, whereas MF was unaffected by this treatment.
