Purpose: Sorafenib is a multikinase inhibitor with antiangiogenic/ antiproliferative activity. A randomized, double-blind, placebo-controlled phase IIB trial assessed sorafenib with capecitabine for locally advanced or metastatic human epidermal growth factor receptor 2 (HER2) -negative breast cancer. Patients and Methods: Patients were randomly assigned to first- or second-line capecitabine 1,000 mg/m 2 orally twice a day for days 1 to 14 of every 21-day cycle with sorafenib 400 mg orally twice a day or placebo. The primary end point was progression-free survival (PFS). Results: In total, 229 patients were enrolled. The addition of sorafenib to capecitabine resulted in a significant improvement in PFS versus placebo (median, 6.4 v 4.1 months; hazard ratio [HR], 0.58; 95% CI, 0.41 to 0.81; P = .001) with sorafenib favored across subgroups, including first-line (HR, 0.50; 95% CI, 0.30 to 0.82) and second-line (HR, 0.65; 95% CI, 0.41 to 1.04) treatment. There was no significant improvement for overall survival (median, 22.2 v 20.9 months; HR, 0.86; 95% CI, 0.61 to 1.23; P = .42) and overall response (38% v 31%; P = .25). Toxicities (sorafenib v placebo) of any grade included rash (22% v 8%), diarrhea (58% v 30%), mucosal inflammation (33% v 21%), neutropenia (13% v 4%), hypertension (18% v 12%), and hand-foot skin reaction/handfoot syndrome (HFSR/HFS; 90% v 66%); grade 3 to 4 toxicities were comparable between treatment arms except HFSR/HFS (44% v 14%). Reasons for discontinuation in the sorafenib and placebo arms included disease progression (63% v 82%, respectively), adverse events (20% v 9%, respectively), and death (0% v 1%, respectively). Conclusion: Addition of sorafenib to capecitabine improved PFS in patients with HER2-negative advanced breast cancer. The dose of sorafenib used in this trial resulted in unacceptable toxicity for many patients. A phase III confirmatory trial has been initiated with a reduced sorafenib dose. © 2012 by American Society of Clinical Oncology. Source

High-resolution melting (HRM) of DNA is a versatile method for mutation scanning that monitors the fluorescence of double-strand DNA with saturating dye. Performing HRM on a real-time thermocycler enables semiquantitative analysis (quantitative polymerase chain reaction, qPCR) to be associated to HRM analysis for detection of both large gene rearrangements and point mutations (qPCR-HRM). We evaluated this method of mutation screening for the two major breast and ovarian cancer susceptibility genes BRCA1 and BRCA2. Screening of these two genes is time-consuming and must include exploration of large rearrangements that represent 5% to 15% of the alterations observed in these genes. To assess the reliability of the HRM technology, 201 known nucleotide variations scattered over all amplicons were tested. The sensitivity of qPCR was evaluated by analyzing seven large rearrangements. All previously identified variants tested were detected by qPCR-HRM. A retrospective study was done with 45 patients: qPCR-HRM allowed all the variants previously tested by denaturing high-performance liquid chromatography to be identified. qPCR analysis showed three cases of allele dropout (due to a 104-bp deletion, SNP primer mismatch, and an Alu insertion). A prospective study was done with 165 patients allowing 22 deleterious mutations, 16 unclassified variants, and 2 rearrangements to be detected. qPCR-HRM is a simple, sensitive, and fast method that does not require modified PCR primers. Thus, this method allows in one step the detection of point mutation, gene rearrangements, and prevention of missing a mutation due to primer mismatch. © 2010, Mary Ann Liebert, Inc. Source

Background.-Idiopathic granulomatous mastitis (IGM) is a benign, aseptic inflammatorydisease of unknown origin, which must be distinguished from tumoral and infectious processesthat affect the breast, including tuberculosis. IGM is a rare cause of erythema nodosum, but itis useful for dermatologists to be aware of this association.Patients and methods.-A 32-year-old nulliparous woman presented with erythema nodosum,arthralgia and fever. On examination, she had a firm and painful mass of 5 cm in the rightbreast with retraction and axillary adenopathy. The breast lump developed gradually over thepreceding 4 months. Although two biopsies showed no evidence of atypical cells, inflammatoryareas and a granulomatous process were seen. Culture of breast tissue for mycobacteria wasnegative. A diagnostic of idiopathic granulomatous mastitis was made. Systemic corticosteroidsled to a reduction in size of the mass, but relapse occurred in the contralateral breast ondose-reduction of the corticosteroids.Discussion.-IGM is a rare disease of unknown aetiology. Diagnosis is based on characteristichistological features and exclusion of other granulomatous diseases. Extra-mammary signs arerare and include erythema nodosum, arthralgia and episcleritis. Management is poorly codified. © 2014 Elsevier Masson SAS. All rights reserved. Source

Few studies have reported reproductive outcomes after breast cancer chemotherapy. The relationship between anti-Müllerian hormone (AMH) concentrations and the occurrence of subsequent pregnancies in women after chemotherapy for breast cancer was investigated. Women aged 18-43 years treated with chemotherapy for invasive breast cancer between May 2005 and January 2011 were retrospectively identified. Exclusion criteria were previous gonadotoxic treatment, oophorectomy or hysterectomy. Measurement of AMH took place before, during chemotherapy and at distant time points after the end of chemotherapy (4 months to 5.5 years). Seventeen out of 134 patients experienced 28 spontaneous pregnancies (median follow-up: 59 months). Neither baseline AMH (divided into quartiles) nor end-of-chemotherapy AMH (detectable versus undetectable) were significantly associated with the occurrence of pregnancy. Chemotherapy regimen with anthracyclines was associated with a greater probability of pregnancy compared with a taxane-containing regimen (hazard ratio 4.75; (95% CI 1.76 to 12.8); P = 0.002). Five-year disease-free survival and overall survival rates were 60% (95% CI: 51 to 70; relapse, n = 48) and 88% (95% CI 82 to 95; deaths, n = 21), respectively. AMH did not predict the occurrence of pregnancy. Additional studies assessing ovarian reserve and reproductive outcomes after breast cancer are required. © 2015 Reproductive Healthcare Ltd. Source

Background: We compared standard adjuvant anthracycline chemotherapy with anthracycline-taxane combination chemotherapy in women with operable node-positive breast cancer. Here we report the final, 10-year follow-up analysis of disease-free survival, overall survival, and long-term safety. Methods: BCIRG 001 was an open label, phase 3, multicentre trial in which 1491 patients aged 18-70 years with node-positive, early breast cancer and a Karnofsky score of 80% or more were randomly assigned to adjuvant treatment with docetaxel, doxorubicin, and cyclophosphamide (TAC) or fluorouracil, doxorubicin, and cyclophosphamide (FAC) every 3 weeks for six cycles. Randomisation was stratified according to institution and number of involved axillary lymph nodes per patient (one to three vs four or more). Disease-free survival was the primary endpoint and was defined as the interval between randomisation and breast cancer relapse, second primary cancer, or death, whichever occurred first. Efficacy analyses were based on the intention-to-treat principle. BCIRG 001 is registered with ClinicalTrials.gov, number NCT00688740. Findings: Enrolement took place between June 11, 1997 and June 3, 1999; 745 patients were assigned to receive TAC and 746 patients were assigned to receive FAC. After a median follow-up of 124 months (IQR 90-126), disease-free survival was 62% (95% CI 58-65) for patients in the TAC group and 55% (51-59) for patients in the FAC group (hazard ratio [HR] 0·80, 95% CI 0·68-0·93; log-rank p=0·0043). 10-year overall survival was 76% (95% CI 72-79) for patients in the TAC group and 69% (65-72) for patients in the FAC group (HR 0·74, 0·61-0·90; log-rank p=0·0020). TAC improved disease-free survival relative to FAC irrespective of nodal, hormone receptor, and HER2 status, although not all differences were significant in these subgroup analyses. Grade 3-4 heart failure occurred in 26 (3%) patients in the TAC group and 17 (2%) patients in the FAC group, and caused death in two patients in the TAC group and four patients in the FAC group. A substantial decrease in left ventricular ejection fraction (defined as a relative decrease from baseline of 20% or more) was seen in 58 (17%) patients who received TAC and 41 (15%) patients who received FAC. Six patients who received TAC developed leukaemia or myelodysplasia, as did three patients who received FAC. Interpretation: Our results provide evidence that the initial therapeutic outcomes seen at the 5-year follow-up with a docetaxel-containing adjuvant regimen are maintained at 10 years. However, a substantial percentage of patients had a decrease in left ventricular ejection fraction, probably caused by anthracycline therapy, which warrants further investigation.
