Women worried about their familial breast cancer risk--a study on genetic advice in general practice

AIMS: To ascertain whether women who consulted their GP because they perceived themselves as at increased risk of familial breast cancer were indeed at increased risk, and to evaluate potential strategies for assessing genetic risk of breast cancer in general practice. METHODS: Sixty-seven out of 81 women who had consulted their GP for advice about their possible increased risk of developing breast cancer due to breast cancer in the family were interviewed. Familial breast cancer risk was assessed by a clinical geneticist. This assessment was compared with two recent guidelines for referral for genetic counselling. RESULTS: More than half (52%; n = 35) the women had a relative risk of two and over for developing breast cancer, while another half of these 35 (25%; n = 17) had a relative risk of three and over. All the women (n = 17) with a relative risk of three and over were identified by means of the two current guidelines for referral for genetic counselling, while more than half of the women (61%; n = 11) with a relative risk between two and three were identified. CONCLUSIONS: More than half the women concerned about their familial risk of breast cancer are indeed at increased risk of breast cancer. Current guidelines correctly identify women at high risk. However, doubts about the health gain and feasibility of referral warrant caution, and need further investigation.      

Spinning top urethra: not a normal variant

Spinning top urethra (STU) is a term used to describe a widened posterior urethra seen mainly in girls. It is commonly regarded as a normal variant. The authors studied 30 girls with STU using videourodynamics. Twenty-eight showed bladder instability; 21, a congenital wide bladder neck anomaly; and 20, both instability and a wide bladder neck. One patient had a sensitive bladder. All patients had a urodynamic abnormality. The authors believe that the STU is nearly always an indication of bladder instability or wide bladder neck anomaly. The most common mechanism for the dilatation of the posterior urethra is that unstable contractions are resisted by a voluntary increase in distal sphincter tension so as to prevent leakage of urine. The resulting pressure rise produces distention of the posterior urethra, which will be maximal in subjects with a weak bladder neck mechanism as in the congenital wide bladder neck anomaly. The authors believe that STU is seldom if ever a normal variant.     

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

Summary 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<0.01). The change in total FACT-B+4 scores (measuring global QOL) closely resembled the TOI results. 18 months post-surgery approximately twice as many patients in the standard group compared with the SNB group reported substantial arm swelling (14% versus 7%) (p=0.002) or numbness (19% versus 8.7%) (p<0.001). Despite the uncertainty about undergoing a relatively new procedure and the possible need for further surgery, there was no evidence of increased anxiety amongst patients randomised to SNB (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.     

Refracture following Fracture Liaison Service Assessment Illustrates the Requirement for Integrated Falls and Fracture Services

The Fracture Liaison Service (FLS) allows appropriate antiosteoporosis therapy to be targeted to potentially reduce future fracture risk. A proportion of these treated patients will still experience a further fracture. This work reviews the characteristics of these patients. Data were collated for patients >65 years old presenting to the South Glasgow FLS between January 2001 and August 2004. There were 2,489 patients who presented (incident fracture group), and 129 (5.2%) sustained an additional fracture (refracture group). Median age of the incident fracture group was 77.8 years vs. 80.6 years for the refracture group (P = nonsignificant). The refracture group was determined according to whether their incident fracture was hip (n = 47) or nonhip (n = 82). When the incident fracture was hip, a refracture was more likely to be a further hip fracture (χ² = 14.4, P = 0.002) and patients refractured sooner (median time to refracture 194 [range 10–1,134] days vs. 258 [range 6–1,081] days [nonhip]) (P = nonsignificant). In the refracture group, 76% of patients were already on osteoporosis treatment after their incident fracture. Patients over 65 years of age presenting to FLS who sustain an additional fracture are older; are likely to sustain another hip fracture after an incident hip fracture; often refracture early, particularly when the incident fracture is of the hip; and are often already on antiosteoporosis treatment. Therefore, it is important to identify these high-risk patients and offer a combined approach of prompt drug treatment through a systematic and specialist osteoporosis management team along with reducing any reversible falls risk factors.
