Abstract

Background: We examined the associations between germline variants and breast cancer mortality using a large meta-analysis of women of European ancestry. Methods: Meta-analyses included summary estimates based on Cox models of twelve datasets using ~10.4 million variants for 96,661 women with breast cancer and 7697 events (breast cancer-specific deaths). Oestrogen receptor (ER)-specific analyses were based on 64,171 ER-positive (4116) and 16,172 ER-negative (2125) patients. We evaluated the probability of a signal to be a true positive using the Bayesian false discovery probability (BFDP). Results: We did not find any variant associated with breast cancer-specific mortality at P < 5 × 10 −8 . For ER-positive disease, the most significantly associated variant was chr7:rs4717568 (BFDP = 7%, P = 1.28 × 10 −7 , hazard ratio [HR] = 0.88, 95% confidence interval [CI] = 0.84–0.92); the closest gene is AUTS2. For ER-negative disease, the most significant variant was chr7:rs67918676 (BFDP = 11%, P = 1.38 × 10 −7 , HR = 1.27, 95% CI = 1.16–1.39); located within a long intergenic non-coding RNA gene (AC004009.3), close to the HOXA gene cluster. Conclusions: We uncovered germline variants on chromosome 7 at BFDP < 15% close to genes for which there is biological evidence related to breast cancer outcome. However, the paucity of variants associated with mortality at genome-wide significance underpins the challenge in providing genetic-based individualised prognostic information for breast cancer patients.

Abstract

Breast cancer risk is influenced by rare coding variants in susceptibility genes, such as BRCA1, and many common, mostly non-coding variants. However, much of the genetic contribution to breast cancer risk remains unknown. Here we report the results of a genome-wide association study of breast cancer in 122,977 cases and 105,974 controls of European ancestry and 14,068 cases and 13,104 controls of East Asian ancestry. We identified 65 new loci that are associated with overall breast cancer risk at P

Abstract

This report highlights the necessity of genetic testing, at least forBRCA1mutations, of young females diagnosed with triple negative breast cancer, even in the absence of or limited family history. A 34-year-old female with a locally advanced, triple negative tumour, which perforated the skin, is described. At the time of diagnosis, the patient had already multiple lung metastases and although chemotherapy was started immediately, she died with rapid systemic disease progression. The patient was found to carry theBRCA1p.E1060X mutation, which is located on exon 11 of the gene. The high penetrance ofBRCA1gene is not represented in the patient’s family, since the mutation was paternally inherited. It is evident that females belonging to small families, along with paternal inheritance of pathogenicBRCAmutations that predispose for breast cancer, in most cases will probably be genetically tested only after being diagnosed with cancer.

Abstract

The docetaxel-cisplatin combination is active against several tumors including gastric cancer but it is followed by severe myelosuppression. Recent experience with weekly taxanes has demonstrated a mild myelotoxicity with high dose intensity. We investigated in a phase I study a weekly schedule of docetaxel on days 1, 8 and 15 and cisplatin on day 1 every 4 weeks in 19 patients with advanced gastric cancer with no prior chemotherapy. Cohorts of patients were treated with escalating doses of docetaxel (starting dose 30 mg/m(2) per week and increments of 10 mg/m(2) per week) and cisplatin (starting dose 70 mg/m(2) and increments of 5 mg/m(2)). Febrile neutropenia was the only dose-limiting event occurring in four (20%) patients; the dose-limiting toxicity was reached at dose level three (docetaxel 40 mg/m(2) per week and cisplatin 75 mg/m(2)). The maximum-tolerated dose was 40 mg/m(2) per week for docetaxel and 70 mg/m(2) every 4 weeks for cisplatin. Grade 3/4 neutropenia occurred in six patients (30%); early death occurred in one patient with septic shock because of neutropenia and another with acute coronary ischemia. Two (11%) complete and two (11%) partial responses were documented (ORR 22%; 95% CI 3-39%), with a median response duration of 5 months and median time to progression of 7 months. In conclusion, the combination of weekly docetaxel plus cisplatin is feasible with moderate toxicity and merits further investigation in phase II studies in advanced gastric cancer.

Abstract

PURPOSE: Amifostine (WR-2721) is an impotant cytoprotective agent. Although intravenous administration is the standard route, pharmacokinetic studies have shown acceptable plasma levels of the active metabolite of amifostine (WR-1605) after subcutaneous administration. The subcutaneous route, due to its simplicity, presents multiple advantages over the intravenous route when amifostine is used during fractionated radiotherapy. PATIENTS AND METHODS: Sixty patients with thoracic, 40 with head and neck, and 40 with pelvic tumors who were undergoing radical radiotherapy were enrolled onto a randomized phase II trial to assess the feasibility, tolerance, and cytoprotective efficacy of amifostine administered subcutaneously. A flat dose of amifostine 500 mg, diluted in 2.5 mL of normal saline, was injected subcutaneously 20 minutes before each radiotherapy fraction. RESULTS: The subcutaneous amifostine regimen was well tolerated by 85% of patients. In approximately 5% of patients, amifostine therapy was interrupted due to cumulative asthenia, and in 10%, due to a fever/rash reaction. Hypotension was never noted, whereas nausea was frequent. A significant reduction of pharyngeal, esophageal, and rectal mucositis was noted in the amifostine arm (P < .04). The delays in radiotherapy because of grade 3 mucositis were significanly longer in the group of patients treated with radiotherapy alone (P < .04). Amifostine significantly reduced the incidence of acute perineal skin and bladder toxicity (P < .0006). CONCLUSION: Subcutaneous administration of amifostine is well tolerated, effectively reduces radiotherapy’s early toxicity, and prevents delays in radiotherapy. The subcutaneous route is much simpler and saves time compared with the intravenous route of administration and can be safely and effectively applied in the daily, busy radiotherapy practice.

Abstract

Introduction It was recently demonstrated that miRNAs control breast cancer metastasis by influencing multiple metastatic steps. In this study we firstly evaluated the clinical relevance of specific miRNAs -recently shown to correlate with metastasis in breast cancer by exploring their expression profile in FFPEs samples of early breast cancer patients in respect to the clinical outcome of the patients. Finally, we investigated the correlations between the expression of these selected miRNAs and other parameters such as ER and PR expression. Materials and Methods One hundred and twelve (112) FFPE blocks were obtained from breast tumors of early breast cancer patients (follow-up period of 11 years) and 13 mammoplasty specimens from healthy tissues which were used as controls. The median overall survival (OS) and disease free interval (DFI) were 84 and 68 months respectively. We have chosen to quantify the expression of six metastasis related miRNAs, namely: miR-10b, miR-2,1 miR-205, miR-210, miR-335 and let-7a by RT-qPCR in the LightCycler (Roche). HER2, ER and PR expression of the primary tumors was detected by immunohistochemistry with the monoclonal antibody CB11 and with monoclonal antibodies to ER and PR, respectively, using the OPTIMAX automated system. For all miRNAs relative expression was determined using the ΔCq approach and expression values were normalized to miR-191 which has been shown to be a suitable reference miRNA. Results Kaplan-Meier survival curves demonstrated that patients with high miR-21 expression (n=56) had a significant shorter DFI than those with low miR-21 expression (P=0.043). Moreover, patients with low expression of miR-205 (n=57) had both shorter DFI and OS time than those with high expression levels (P=0.040 and P=0.047 respectively). However, the expression levels of the other four miRNAs were not related with the DFI and OS. We also found that in the ER-negative subgroup (n=46), disease relapse was more common in patients where miR-10b was over-expressed (P=0.019), while in the PR-negative subgroup (n=47), disease relapse was more common in patients with miR-21 overexpression (P Conclusions Quantification of metastasis related miRNAs expression in primary tumors can give important prognostic information in patients with early breast cancer.
