OBJECTIVE To evaluate the sensitivity of sentinel node (SN) ultrastaging and to define parameters that may reduce the overall false-negative rate in women with early-stage cervical cancer. METHODS We analyzed data from a large retrospective multicenter cohort group with FIGO stages IA-IIB cervical cancer in whom at least one SN was identified and(More)
Aryl hydrocarbon receptor (AhR), or dioxin receptor, is a transcription factor that induces adaptive metabolic pathways in response to environmental pollutants. Recently, other pathways were found to be altered by AhR and its ligands. Indeed, developmental defects elicited by AhR ligands suggest that additional cellular functions may be targeted by this(More)
OBJECTIVE To study the correlation between the nature of the ovarian tumors presumed according to the ultrasound criteria of Timmerman and the final histological diagnosis. PATIENTS AND METHODS We made a prospective study during a period of 4 years, concerning consecutive patients having an ovarian tumor, investigated by pelvic ultrasonography using(More)
OBJECTIVE Evaluate prognostic significance of low volume disease detected in sentinel nodes (SN) of patients with early stages cervical cancer. Although pathologic ultrastaging of SN allows for identification of low volume disease, including micro-metastasis and isolated tumor cells (ITC), in up to 15% of cases, prognostic significance of these findings is(More)
The purpose of this prospective multicenter study was to assess one-step nucleic acid amplification (OSNA) for intraoperative sentinel lymph node (SLN) metastasis detection in breast cancer patients, using final histology as the reference standard. OSNA results were also compared to intraoperative histology SLN evaluation and to standard clinicopathological(More)
The contribution of environmental pollutants to liver fibrosis is an important and poorly explored issue. In vitro studies suggest that the environmental pollutant 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) and other aryl hydrocarbon receptor (AhR) ligands induce several genes that are known to be upregulated during liver fibrosis. Our aim was to determine(More)
BACKGROUND Sentinel lymph node (SLN) biopsy may improve nodal staging in cervical cancer. The aims of this study are to determine the rate of unusual patterns of cervical lymphatic drainage, to determine the rates of micrometastases and isolated tumor cells (ITCs) in SLNs, and to assess the clinical impact of SLN biopsy. METHODS Multicenter prospective(More)
The objective of this study was to report the value of diagnostic hysteroscopy and endometrial biopsy for the detection of complex atypical hyperplasia or cancer in asymptomatic human non-polyposis colon cancer (HNPCC) patients. The secondary objective was to evaluate the accuracy of hysteroscopy, using endometrial biopsy as a gold standard. Consecutive(More)
INTRODUCTION Symptomatic postoperative lymphocysts (SPOLs) and lower-limb lymphedema (LLL) are probably underestimated complications of lymphadenectomy for gynecologic malignancies. Here, our objective was to evaluate the incidence and risk factors of SPOLs and LLL after pelvic and/or aortocaval lymphadenectomy for gynecologic malignancies. METHODS(More)
OBJECTIVES To map sentinel lymph nodes (SLNs) detected by intracervical injection in patients with endometrial cancer and to determine the prevalence of node micrometastases. METHODS Radionuclide and blue dye injections were used for SLN detection in 43 patients with clinical stage I endometrial cancer. Lymphoscintigraphy was done before surgery.(More)
