INTRODUCTION Neoadjuvant systemic therapy (NST) is an established strategy to reduce tumor size in breast cancer patients prior to breast-conserving therapy. The effect of NST on tumor cell dissemination in these patients is not known. The aim of this study was to investigate the incidence of disseminated tumor cells (DTC), including apoptotic DTC, in(More)
INTRODUCTION Isolated disseminated tumour cells (DTC) are regarded as surrogate markers for minimal residual disease in breast cancer. Characterisation of these cells could help understand the known limitations of adjuvant therapy. Of particular interest is their oestrogen-receptor (ER) status because endocrine adjuvant therapy remains a cornerstone of(More)
In Uganda, the HIV Network for Prevention Trials (HIVNET) 012 study recently demonstrated that single-dose nevirapine (Nvp) prophylaxis is effective for preventing mother-to-child transmission (MTCT) of human immunodeficiency virus type 1 (HIV-1). This exploratory study examines the relationship between HIV-1 subtype, MTCT, and the development of Nvp(More)
Virologic factors may influence survival of HIV-1-infected infants. We compared survival of Ugandan infants with subtype A and subtype D HIV-1 infection. This study was performed in the context of the Ugandan clinical trial HIVNET 012, which compared the efficacy of single-dose nevirapine (NVP) and short-course zidovudine (AZT) for prevention of HIV-1(More)
Y. Unexpected relationship between plasma homocysteine and intrauterine growth restriction. Perinatal reference intervals for plasma homo-cysteine and factors influencing its concentration. Despite histopathologic evidence of tumor-free margins, many breast cancer patients suffer from recurrence of their disease. This may reflect the presence of(More)
