    ABSTRACT: OBJECTIVES: The incidence of neonatal respiratory morbidity following an elective caesarean section is 2-3 times higher than after a vaginal delivery. The microviscosity of surfactant phospholipids, as measured with fluorescence polarisation, is linked with the functional characteristics of fetal surfactant and thus fetal lung maturity, but so far this point has received little attention in new-borns at term. The aim of the study is to evaluate the correlation between neonatal respiratory morbidity and amniotic microviscosity (Fluorescence Polarisation Index) in women undergoing caesarean section after 37 weeks' gestation. STUDY DESIGN: The files of 136 women who had undergone amniotic microviscosity studies during elective caesarean deliveries at term were anonymised. Amniotic fluid immaturity (AFI) was defined as a Fluorescence Polarisation Index higher than 0.335. RESULTS: Respiratory morbidity was observed in 10 babies (7.3%) and was independently associated with AFI (OR: 6.11 [95% CI, 1.20-31.1] with p=0.029) and maternal body mass index (OR: 1.12 [95% CI, 1.02-1.22] with p=0.019). Gestational age at the time of caesarean delivery was inversely associated with AFI (odds ratio, 0.46 [95% confidence interval, 0.29-0.71], p<0.001), especially before 39 weeks, and female gender was associated with an increased risk (odds ratio, 3.29 [95% confidence interval, 1.48-7.31], p=0.004). CONCLUSIONS: AFI assessed by amniotic microviscosity was significantly associated with respiratory morbidity and independently correlated with shorter gestational age especially before 39 weeks. This finding provides a physiological rationale for recommending delaying elective caesarean section delivery until 39 weeks of gestation to decrease the risk for respiratory morbidity.

    ABSTRACT: The treatment of locally advanced cervical carcinoma of uterine cervix is based on concurrent chemoradiotherapy (CCR). The role of laparoscopic lymphadenectomy before CCR and hysterectomy after CCR is not consensual. Retrospective multicentric study on 102 patients treated for locally advanced carcinoma of uterine cervix between 1999 and 2008. Disease-free survival and overall survival (OS) were studied. Stages were: stage IB 42%, II 47% and stage III and IVA 11%. All patients received CCR. Eighty-one patients had associated brachytherapy. Sixty-two patients underwent laparoscopic lymphadenectomy before CCR and 31 patients had also para-aortic lymphadenectomy. Eighty-two patients had hysterectomy after CCR. Forty-seven percent (29/62) of patients had a histologically proven pelvic lymph node involvement and 58% (18/31) had a histologically proven para-aortic lymph node involvement. There is no predictor of the presence of residual tumor on hysterectomy. The lymph node involvement before treatment and the presence of residual tumor on hysterectomy were poor prognostic factors on relapse-free survival (SSR) and OS. It has not been shown to benefit from surgery pre- or post-CCR on survival. Surgery can provide major prognosis factor and especially lymphadenectomy before CCR can improve the therapeutic strategy but does not demonstrate significant survival benefit.

    ABSTRACT: To determine factors predictive of the presence of residual tumor on the specimen from mastectomy performed after conservative treatment for breast cancer in order to limit potentially unnecessary mastectomies (free of residual lesions). 294 patients treated in 2 expert centers for breast cancer with breast-conserving therapy (BCT) followed by mastectomy, according to French recommendations, were investigated between January 1, 1998 and January 1, 2005. Patients with residual tumor on the mastectomy specimen were compared with patients whose mastectomy specimens did not reveal any residual tumor. All the clinical risk factors (age, previous history of breast cancer, tumor focality) and histological risk factors (tumor size, histological type, positive margins, estrogen and progesterone receptor expression, histological grade) for residual tumor after BCT were compared between the 2 patient groups. Of the 294 patients studied, 202 (68.71%) mastectomies had residual tumor and 92 (31.29%) were tumor-free. Four predictive factors for residual tumor were found in the univariate analysis: age under 45 years (p=0.01), absence of estrogen receptor expression (p=0.05), positive margins (p=0.01), and presence of lymph node metastases (p=0.05). The multivariate analysis revealed only 2 independent risk factors that were significantly associated with increased risk of residual tumor on the mastectomy specimen: age under 45 years (p=0.05) and presence of positive margins on the lumpectomy specimen (p=0.05). Young age of patients (under 45-years-old) and presence of positive margins on the operative specimen are independent risk factors of residual tumor after conservative treatment of breast cancer.
