RESUMEN

BACKGROUND: In endometrial cancer (EC), sentinel lymph node (SLN) mapping has emerged as an alternative to systematic lymphadenectomy. Little is known about factors that might influence SLN preoperative detection. The aim of our study was to evaluate the clinical and technical variables that may influence on the success of SLN detection in preoperative lymphatic mapping in patients with intermediate and high-risk EC when performing transvaginal ultrasound-guided myometrial injection of radiotracer (TUMIR). METHODS: Between March 2006 and March 2017, we prospectively enrolled patients with histologically confirmed EC with intermediate or high-risk of lymphatic involvement. All women underwent SLN detection by using TUMIR approach. After radiotracer injection, pelvic and abdominal planar and SPECT/CT images were acquired to obtain a preoperative lymphoscintigraphic mapping. Pattern of drainage was registered and analyzed to identify the factors directly involved in drainage. Sonographer learning curves to perform TUMIR approach were created following Cumulative Sum and Wright methods. Univariate and multivariate analyses were performed using logistic regression. RESULTS: During study period, 123 patients were included. SLN preoperative detection rate was 70.7%. Age under 75 years at diagnosis (P<0.01), radiotracer injection above 4 mL -high-volume- (P<0.01), and tumoral size below 2 cm (P=0.04) were associated with higher SLN preoperative detection rate. Twenty-five procedures were necessary to attain an adequate performance in TUMIR approach. CONCLUSIONS: The higher SLN preoperative detection rate in women with intermediate and high-risk endometrial cancer after TUMIR approach was related with younger age, smaller tumors and high-volume injection of radiotracer. Sonographers are required to perform 25 procedures before acquiring an expertise in radiotracer injection.

RESUMEN

Preservation of ovarian function is important for the physical and psychosexual well-being of young patients with cancer. Patients with pelvic malignancies such as cervical or rectal cancer planned for radiotherapy may benefit from ovarian transposition with the aim of moving the ovaries outside the radiation field.1 Different surgical techniques have been reported previously.2,3 With the present video, we aim to standardize the surgical technique of laparoscopic ovarian transposition in ten steps. We present the case of a 30-year-old nulliparous woman diagnosed with grade 3 squamous cell cervical carcinoma having a largest tumor diameter of 41 mm on magnetic resonance imaging (MRI) scan. The tumor was staged as FIGO 2018 stage IIIC1r with a common iliac lymphadenopathy reported on both MRI and positron emission tomography (PET)/computed tomography (CT) scan. The multidisciplinary team recommended exclusive chemoradiation extended to paraaortic area. The patient underwent laparoscopic bilateral salpingectomy and bilateral ovarian transposition with extraperitonealization of the infundibulopelvic ligament. The procedure was divided into the following ten steps: division of uteroovarian ligament, incision of lateral pelvic peritoneum, identification of ureter, incision of medial pelvic peritoneum, skeletonization of the infundibulopelvic ligament, retroperitoneal tunnel in paracolic gutter, creating the window (as high as possible), mobilization of the ovary without torsion, intraperitonealization of the ovary, and fix ovary with clips (Fig. 1). Surgical time was 30 min, with minimal estimated blood loss. No intra- or postoperative complication was recorded. The patient started radiotherapy 14 days after the procedure. In conclusion, we showed that laparoscopic ovarian transposition in cervical cancer before radiotherapy can be standardized in ten steps with encouraging perioperative results, making it an easily reproducible procedure. Ovarian function is reported to be preserved in 62-65% of cases undergoing ovarian transposition and radiation therapy.4,5 Fig. 1 Laparoscopic view of right ovary transposed below the liver edge after extraperitonealization of the infudibulopelvic ligament.

RESUMEN

OBJECTIVE: To evaluate the influence of perinatal inflammation on neurodevelopmental outcome of premature infants. STUDY DESIGN: From a retrospective cohort study of women with preterm labor with intact membranes or preterm prelabor rupture of membranes (PPROM) with an amniocentesis to rule out intra-amniotic inflammation (IAI) and microbial invasion of the amniotic cavity (MIAC), we evaluated neurodevelopmental outcome of their infants born between 24.0 and 34.0 weeks gestation. Women with clinical chorioamnionitis at admission were excluded. Neurodevelopmental outcome was screened with the Ages & Stages Questionnaire (ASQ)-3. We analyzed the relationship between an altered ASQ-3 and antenatal, intra-partum and post-partum factors related to perinatal inflammation. RESULT: Among 98 infants evaluated, 22% had an abnormal score. Amniotic fluid interleukin-6 levels and early-onset sepsis (EOS) were independent factors of an altered ASQ-3 with delivery <26.0 weeks being the strongest predictor. CONCLUSIONS: In premature infants, the presence of IAI, delivery <26.0 weeks and EOS were found to be independent factors of an altered ASQ-3.
