Netrins are secreted molecules with roles in axon guidance and angiogenesis. We identified Netrin-4 as a gene specifically overexpressed in VEGF-stimulated endothelial cells (EC) in vitro as well as in vivo. Knockdown of Netrin-4 expression in EC increased their ability to form tubular structures on Matrigel. To identify which receptor is involved, we(More)
BACKGROUND The aims of the study were to investigate the factors associated with not having breast reconstruction following mastectomy and to assess patient satisfaction with information on reconstruction. PATIENTS AND METHODS We analysed a historical cohort of 1937 consecutive patients who underwent mastectomy at Institut Curie between January 2004 and(More)
BACKGROUND Lymph node status is an important prognostic factor and a criterion for adjuvant therapy in uterine cancers. While detection of micrometastases by ultrastaging techniques is correlated to prognosis in several other cancers, this remains a matter of debate for uterine cancers. The objective of this review on sentinel nodes (SN) in uterine cancers(More)
A close relationship between tumor angiogenesis, growth, and carcinomatosis has been observed. Netrin-4 (NT-4) has been shown to regulate angiogenic responses. We aimed to examine the effects of NT-4 on colon tumor angiogenesis, growth, and carcinomatosis. We showed that NT-4 was expressed in human colon cancer cells (LS174). A 20-fold increase in NT-4(More)
INTRODUCTION To decipher the interaction between the molecular subtype classification and the probability of a non-sentinel node metastasis in breast cancer patients with a metastatic sentinel lymph-node, we applied two validated predictors (Tenon Score and MSKCC Nomogram) on two large independent datasets. MATERIALS AND METHODS Our datasets consisted of(More)
PURPOSE The purpose of this study was to evaluate the outcome of breast conserving surgery comparing oncoplastic surgery (OS) and standard lumpectomy (SL) after preoperative bracketing wire localization of large neoplastic lesions. METHODS We retrospectively reviewed the medical records and the mammograms of patients operated on at the Institut Curie(More)
BACKGROUND Molecular signatures may become of use in clinical practice to assess the prognosis of breast cancers. However, although international consensus conferences sustain the use of these new markers in the near future, concerns remain about their degree of discordance and cost-effectiveness in different international settings. The present study aims(More)
INTRODUCTION Breast cancer surgery is suitable for outpatient practice. Indeed, this is a planned surgery with short operative time. Objective was to evaluate the recognized success indicators in day surgery: rate of conversion into conventional hospitalization, rate of complications and re-hospitalizations the month following surgery. METHODS Consecutive(More)
BACKGROUND The poor prognosis of patients who experience ipsilateral breast tumor recurrence (IBTR) after breast conserving surgery (BCS) is established. A short time between primary cancer and IBTR is a prognostic factor but no clinically relevant threshold was determined. Classification of IBTR may help tailor treatment strategies. PURPOSE We determined(More)
