OBJECTIVE We aimed to determine the feasibility and accuracy of sentinel node (SN) mapping and its ability to predict the status of the regional nodal basin. METHODS From October 2000 to September 2002, 70 patients undergoing radical surgery for early-stage cervical cancer (stage IA, IB, and IIA) were offered lymph node mapping for identification of the(More)
OBJECTIVE To report the obstetrical results following vaginal radical trachelectomy (VRT), a fertility-preserving surgery in the treatment of early-stage cervical cancer. METHODS Retrospective review of our first 72 patients treated by a laparoscopic pelvic lymphadenectomy followed by a VRT from October 1991 to October 2003 with regards to their(More)
OBJECTIVE To review our first consecutive 125 vaginal radical trachelectomies (VRT) to assess the oncologic, fertility and obstetrical outcomes. METHODS Data from our prospective database was used to identify all VRT planned between October 1991 to March 2010 in patients with early-stage cervical cancer (stages IA, IB and IIA). Chi-square test, Fisher's(More)
BACKGROUND The use of a standardized triage tool allows better comparison of the patients; a computerized version could theoretically improve its reliability. OBJECTIVES To compare the interrater agreement of the Pediatric Canadian Triage and Acuity Scale (PedCTAS) and a computerized version (Staturg). METHODS A two-phase experimental study was(More)
OBJECTIVE To evaluate the long-term recurrence rates and complication of different techniques of cervical ablation. METHODS A randomized trial of three techniques of conization (cold knife, laser, and loop electrosurgical excisional procedure (LEEP)) for cervical intraepithelial neoplasia (CIN) in which 110 patients had been recruited. RESULTS(More)
We report on 162 cases of human papillomavirus (HPV) infection of the cervix seen in a two-year period in which the cell sample showed such marked atypia that errors of interpretation could easily have been made. These atypical condylomata are difficult to diagnose cytologically as well as histologically because they mimic dysplasia or carcinoma in situ(More)
Three different techniques of cervical excision, cold knife conization, laser conization, and loop electrosurgical excisional procedure (LEEP) were prospectively compared with respect to treatment reliability, effectiveness, and safety. One hundred ten women with CIN1-2 and the squamnocolumnar junction not seen or CIN3 at the original diagnosis were(More)
OBJECTIVE The purpose of this study was to evaluate the role of fertility-preserving surgery in the treatment of early-stage cervical cancer. STUDY DESIGN We retrospectively reviewed our first 30 patients treated by laparoscopic pelvic lymphadenectomy, followed by radical vaginal trachelectomy, from October 1991 to April 1998. RESULTS The median age of(More)
OBJECTIVES To compare the relative value of two methods of detection for the sentinel lymphatic nodes (SLNs): colorimetric with Isosulfan blue (ISB) and radio-isotopic with Technetium-99 (Tc99), and to evaluate the concept of the SLN mapping applied to cervical cancer. METHODS From October 2000 to December 2006, radical surgery was planned in 211 patients(More)
Hypertrophic scarring is a pathological process characterized by fibroblastic hyperproliferation and by excessive deposition of extracellular matrix components. It has been hypothesized that abnormalities in epidermal-dermal crosstalk explain this pathology. To test this hypothesis, a tissue-engineered model of self-assembled reconstructed skin was used in(More)
