Highly favorable outcome in BRCA-mutated metastatic breast cancer patients receiving high-dose chemotherapy and autologous hematopoietic stem cell transplantation.

Breast cancer carrying BRCA mutation may be highly sensitive to DNA-damaging agents. We hypothesized a better outcome for BRCA-mutated (BRCA(mut)) metastatic breast cancer (MBC) patients receiving high-dose chemotherapy and autologous hematopoietic stem cell transplantation (HDC AHSCT) versus unaffected BRCA (BRCA wild type; (BRCA(wt))) or patients without documented BRCA mutation (BRCA untested (BRCA(ut))). All female patients treated for MBC with AHSCT at Institut Paoli-Calmettes between 2003 and 2012 were included. BRCA(mut) and BRCA(wt) patients were identified from our institutional genetic database. Overall survival (OS) was the primary end point. A total of 235 patients were included. In all, 15 patients were BRCA(mut), 62 BRCA(wt) and 149 BRCA(ut). In multivariate analyses, the BRCA(mut) status was an independent prognostic factor for OS (hazard ratio (HR): 3.08, 95% confidence interval (CI): 1.10-8.64, P=0.0326) and PFS (HR: 2.52, 95% CI :1.29-4.91, P=0.0069). In this large series of MBC receiving HDC AHSCT, we report a highly favorable survival outcome in the subset of patients with documented germline BRCA mutations.

Double-blind randomized evaluation of clinical and biological tolerance of polyethylene glycol 4000 versus lactulose in constipated children.

OBJECTIVES: To assess the safety of a polyethylene glycol (PEG) 4000 laxative without additional salts in pediatric patients. STUDY DESIGN: This was a 3-month multicenter, randomized, double-blind, double-dummy, lactulose-controlled, parallel study enrolling 96 ambulatory constipated children aged 6 months to 3 years, treated daily with 4-8 g PEG or 3.33 g-6.66 g lactulose. Total protein, albumin, iron, electrolytes, and vitamins B9 (folates), A and D (25OHD3) were measured in blood before and after treatment (day 84) in a central laboratory. RESULTS: The percentage of children with at least one value out of normal range at day 84 with respect to baseline status (with or without at least one value out of normal range), i.e. the primary endpoint, was 87% and 90% in the PEG and lactulose groups, respectively, without any difference between groups. The whole blood parameters showed no qualitative or quantitative treatment-related changes. Vitamin A values were above normal range in 56% and 41% of children at baseline versus 33% and 36% at day 84 in the PEG and lactulose groups, respectively. Iron values were similarly under normal range in 47% and 51% at baseline versus 42% and 51% at day 84. Clinical tolerance was similar for both treatments except for vomiting and flatulence, which were significantly higher with lactulose. Significantly higher improvements were evidenced with PEG regarding stool consistency, appetite, fecaloma and use of additional laxatives. CONCLUSION: This 3-month study in 96 constipated children aged 6 months to 3 years confirms the long-term tolerance of PEG 4000 in pediatrics and indicates a PEG efficacy similar to or greater than that of lactulose.

[Background music in the family physician's surgery: patient reactions].

Music is a universal language, and its effects on pain relief and stress reduction are well known. We evaluated patients' opinions of the effects of background music in their family doctors' surgery. Low volume, background, classical music was played in the doctors' surgery on 5 consecutive clinic days. All patients were asked to fill a short anonymous questionnaire on leaving. Among the 135 consecutive patients offered the questionnaire, there was 87.4% compliance. Among the 118 who completed the questionnaire, 95% said that the background music did not disturb them, 89% thought it made them feel better and 80% thought that it aided the doctor's performance. We conclude that low volume, background music in the doctors's surgery may contribute to better doctor-patient interaction, although larger studies are needed to confirm our findings.
