Flemish obstetricians' personal preference regarding induction of labor and mode of delivery in term births.

INTRODUCTION: In a 2002 survey, 2% of Flemish gynecologists preferred elective cesarean section for themselves or their partner. This study aims to determine actual preference regarding induction of labor and mode of delivery in term cephalic or breech births for gy- necologists or their partners. MATERIALS AND METHODS: An anonymous postal questionnaire was sent to all gynecologists and trainees in Flanders. RESULTS: Response rate was 28.2 % (241/852). In case of an uncomplicated cephalic singleton pregnancy, 39 gynecologists (16.2%) preferred cesarean section. Most (n=134, 66.5%) chose induction at 41 weeks, 26 (13%) at 40 weeks, 37 (18%) at 42 weeks, 26 (13%) at 40 weeks, three (1.5%) preferred induction before 40 weeks and two (1%) would wait until after 42 weeks. Concerning term breech, 30% (n=72) opted for vaginal delivery and 70% (n = 169) for planned cesarean section. Ninety-nine (41%) gynecologists pre- ferred to attempt external version first. Only 115 (47.7 %) gynecologists felt professionally capable to assist vaginal breech delivery them- selves; about one-third (n=96; 38%) had performed less than ten vaginal breech deliveries in their career. CONCLUSIONS: Flemish gynecologists are still in favor of vaginal delivery for themselves in terms of cephalic position, but an increasing number favor planned cesarean section. Most Flemish gynecologists opt for cesarean section for themselves or their partners in case of term breech and state that they do not feel capable in assisting vaginal breech delivery for their patients.

Sentinel node detection in a patient with recurrent endometrial cancer initially treated by hysterectomy and radiotherapy.

This is the first article reporting sentinel node identification in a patient with endometrial cancer recurring in the vagina. A 79-year-old woman presented with a midvaginal recurrence of a stage IB, grade II endometroid carcinoma that had been treated 3 years earlier by a total abdominal hysterectomy, bilateral salpingoophorectomy, and pelvic lymph node sampling, followed by adjuvant brachytherapy to the vaginal vault. A staging examination under anesthetic was performed. Preoperatively, 60-MBq technetium-labeled nannocolloid was injected in the mucosa at 3, 6, 9, and 12 o'clock just adjacent to the tumor recurrence. Three sentinel nodes were detected, respectively, in the left obturator fossa (two) and the right external iliac region, using a laparoscopic probe (Navigator) and removed for pathological assessment. As they proved to be negative, the patient underwent a total vaginectomy, parametrectomy with pelvic lymphadenectomy. The tumor was completely removed, and all lymph nodes proved to be negative. The accuracy of sentinel node identification in patients with recurrent gynecological tumors needs further evaluation. This unique case shows that sentinel node detection is possible after previous radiotherapy and surgery and hopes to stimulate further research in this field.

Intraoperative sentinel node identification with Technetium-99m-labeled nanocolloid in patients with cancer of the uterine cervix: a feasibility study.

The objective of this study is to determine the feasibility of intraoperative lymphatic mapping in patients with cervical carcinoma. Patients with early-stage cervical cancer, scheduled to undergo a Wertheims radical hysterectomy and pelvic lymphadenectomy, were eligible for the study. Technetium-99-m-labeled nanocolloid was injected intracervically at two locations around the tumor 3-6 hours before the operation. Images were recorded immediately and 2.5 hours later using a gamma camera. During the operation sentinel nodes (SLN) were identified using a handheld or laparoscopic gamma-detection probe (Navigator, Auto-Suture). After resection of the SLNs a standard pelvic (and para-aortic) lymphadenectomy was performed. The results of the histopathology of SLNs and non-SLNs were compared. The procedure was well tolerated by 24 of 25 patients. One or more SLN could be identified in 21 out of 25 patients. In one patient who was preoperatively irradiated, in two patients who had had a cone biopsy, and in one patient without previous interventions, no SLN could be detected. The mean time for identification was 5 minutes. In 16 patients, pathologic examination showed no metastatic disease in both SLNs and non-SLNs, whereas metastases were found in the SLN in five patients (in one case only SLN involved, four cases SLN and respectively 3, 11, 22 and 31 other positive nodes). This study shows that identification of SLNs in cancer of the uterine cervix is feasible with preoperatively administered 99mTc-labeled nanocolloid. To date, no false negative SLNs have been found, but expansion of the study is necessary to determine possible clinical application of this new technique.

Angiogenesis in cervical intraepithelial neoplasia and the risk of recurrence.

OBJECTIVE: We sought to investigate whether angiogenesis can predict the risk of recurrence of cervical intraepithelial neoplasia after treatment. STUDY DESIGN: Microvessel density was studied in 75 patients with grade 3 cervical intraepithelial neoplasia and in 20 patients with microinvasive squamous carcinoma (International Federation of Gynecology and Obstetrics stage IA1) of the uterine cervix by staining representative tissue sections with the specific endothelial marker anti-CD31. The microvessel density was determined with a digital image analyzer. The results were correlated with clinical and histopathologic data. RESULTS: The mean vessel density was 264 per field (range, 86-674 per field) in grade 3 cervical intraepithelial neoplasia and 378 per field (range, 161-848 per field; P = .001) in microinvasive squamous carcinoma. Thirteen patients with grade 3 cervical intraepithelial neoplasia had recurrent cervical intraepithelial neoplasia (microvessel density, recurrent vs nonrecurrent; not significant). Multiple regression analysis in the noninvasive group confirmed that the mean vessel density (P = .121) had no prognostic value. Furthermore, it showed that the age at diagnosis (P = .011), menopausal status (P = .052), and treatment modality (P = .022) proved to be independent prognostic factors for recurrence. CONCLUSIONS: During the progression from noninvasive to microinvasive cervical carcinoma, the microvessel density increases significantly. However, the vessel density does not predict recurrence of noninvasive lesions.
