OBJECTIVE To determine the factors associated with false-negative results on sentinel node biopsy and sentinel node localization (identification rate) in patients with breast cancer enrolled in a multicenter trial using a combination technique of isosulfan blue with technetium sulfur colloid (Tc99). SUMMARY BACKGROUND DATA Sentinel node biopsy is a(More)
This paper analyzes in-depth interviews with 26 black women who entered the medical system in rural North Carolina with advanced breast disease. In these narratives, women draw on multiple sources of knowledge in order to come to terms with the diagnosis of breast cancer--a biomedically-defined disease that they often refuse to acknowledge or accept. The(More)
BACKGROUND The mechanisms underlying a reported tendency for women who hold strong religious beliefs to seek medical help at more advanced stages of breast cancer are unknown. This study investigates further the effect of religious beliefs with other variables on breast cancer screening and the intended presentation of a self-discovered breast lump. (More)
BACKGROUND Several recent studies have described increasing rates of unilateral and bilateral mastectomy among women with newly diagnosed breast cancer. The use of breast magnetic resonance imaging (MRI) has also risen rapidly, leading to speculation that the high false-positive rate and need for multiple biopsies associated with MRI may contribute to more(More)
CONTEXT Breast cancer mortality is higher among African American women than among white women in the United States, but the reasons for the racial difference are not known. OBJECTIVE To evaluate the influence of socioeconomic and cultural factors on the racial difference in breast cancer stage at diagnosis. DESIGN Case-control study of patients(More)
BACKGROUND Neoadjuvant chemotherapy has been shown to increase the rate of breast conservation in clinical trials and small institutional series, but it has never been studied on a national level. STUDY DESIGN We performed a retrospective review of the National Cancer Database (NCDB). The NCDB is a joint project of the Commission on Cancer of the American(More)
BACKGROUND Routine resection of cavity shave margins (additional tissue circumferentially around the cavity left by partial mastectomy) may reduce the rates of positive margins (margins positive for tumor) and reexcision among patients undergoing partial mastectomy for breast cancer. METHODS In this randomized, controlled trial, we assigned, in a 1:1(More)
BACKGROUND Neoadjuvant chemotherapy (NAC) is the standard of care for patients with locally advanced breast cancer and can yield clinical advantages in individuals with lower stage cancers as well. To the authors' knowledge, the extent and patterns of use of NAC remain unknown. The objective of the current study was to assess temporal trends in NAC use and(More)
There is an increasing interest in using single nucleotide polymorphism (SNP) genotyping arrays for profiling chromosomal rearrangements in tumors, as they allow simultaneous detection of copy number and loss of heterozygosity with high resolution. Critical issues such as signal baseline shift due to aneuploidy, normal cell contamination, and the presence(More)
BACKGROUND Sentinel lymphadenectomy (SL) for breast cancer is becoming the standard of care for selected patients treated by experienced surgeons. One of the few contraindications for performing SL alone is prior chemotherapy (PC). There are, however, no data to support that PC interferes with the ability of the sentinel node to predict the presence of(More)
