Respective Prognostic Value of Genomic Grade and Histological Proliferation Markers in Early Stage (pN0) Breast Carcinoma

Genomic grade (GG) is a 97-gene signature which improves the accuracy and prognostic value of histological grade (HG) in invasive breast carcinoma. Since most of the genes included in the GG are involved in cell proliferation, we performed a retrospective study to compare the prognostic value of GG, Mitotic Index and Ki67 score.A series of 163 consecutive breast cancers was retained (pT1-2, pN0, pM0, 10-yr follow-up). GG was computed using MapQuant Dx(R).GG was low (GG-1) in 48%, high (GG-3) in 31% and equivocal in 21% of cases. For HG-2 tumors, 50% were classified as GG-1, 18% as GG-3 whereas 31% remained equivocal. In a subgroup of 132 ER+/HER2- tumors GG was the most significant prognostic factor in multivariate Cox regression analysis adjusted for age and tumor size (HR = 5.23, p = 0.02).In a reference comprehensive cancer center setting, compared to histological grade, GG added significant information on cell proliferation in breast cancers. In patients with HG-2 carcinoma, applying the GG to guide the treatment scheme could lead to a reduction in adjuvant therapy prescription. However, based on the results observed and considering (i) the relatively close prognostic values of GG and Ki67, (ii) the reclassification of about 30% of HG-2 tumors as Equivocal GG and (iii) the economical and technical requirements of the MapQuant micro-array GG test, the availability in the near future of a PCR-based Genomic Grade test with improved performances may lead to an introduction in clinical routine of this test for histological grade 2, ER positive, HER2 negative breast carcinoma

Importance of Providing Tailored Resources to Patients with Metastatic Breast Cancer: Results of the Global BRIDGE Survey

Life expectancy for women with metastatic breast cancer (MBC) has increased as advances have been made in treatment and management. Consequently, when measuring the burden of MBC, womens' experiences, quality of life, and gaps in information and support needs should be considered. The BRIDGE Survey (Bridging Gaps, Expanding Outreach – Metastatic Breast Cancer Patient Survey) was conducted in the US, Europe, Latin America and Africa to evaluate patients' (pts) own perceptions of living with MBC; results are presented here

Living with metastatic breast cancer: a global patient survey

Worldwide, one-third of patients who present with early-stage breast cancer will go on to develop metastatic disease. Despite a serious diagnosis with a grave prognosis, treatment advances have meant that women are living longer with metastatic breast cancer. Although the clinical aspects of metastatic breast cancer have been well studied, little is known about the personal, psychosocial, and emotional experiences of women living with the disease. Because early-stage breast cancer is highly visible in the media and is a focus for most patient advocacy groups, women with metastatic disease feel isolated and alone. This paper presents the results of an international survey that questioned 1,342 women with metastatic breast cancer from 13 countries. The survey was designed to understand the nonmedical attitudes of patients living with metastatic breast cancer, identify perceived gaps in resources available to these patients, and define barriers to clinical trial enrollment and participatio
