The Relationship Between the Site of Metastases and Outcome in Children With Stage IV Wilms Tumor: Data From 3 European Pediatric Cancer Institutions

The aim of this study was to analyze in detail the site of metastasis of stage 4 Wilms tumor (WT) and its correlation with outcome. The databases from 3 major European pediatric cancer institutions were screened for children with WT between 1994 and 2011. Of 208 children identified, 31 (14.9%) had metastases at diagnosis. The lung was affected in 29 children (93.5%) and the liver in 6 children (19.4%). Twenty-seven children (87.1%) had metastases isolated to 1 organ, with the lung being the most common site (80.7%). Five-year overall survival was significantly better in those children with distant disease in either lung or liver (95.8%) compared with those affected in both lung and liver (57.1%, P=0.028). Further, prognostic markers were the response of metastases to preoperative chemotherapy (P=0.0138), high-risk histology (P=0.024), and local stage (P=0.026). Five-year overall survival was 82.1% and 5-year event-free survival was 67.9%. The overall follow-up time was 74.1 and 87.2 (2 to 151) months among survivors, and the treatment-related complication rate was 16.7%. In conclusion, in our series of stage 4 WT, prognosis was excellent if histology was favorable, metastatic disease was isolated to either lungs or liver, and if metastases responded to preoperative chemotherapy

Vascular tumors and malformations of the colon

The term “hemangioma” refers to the common tumor of infancy that exhibits rapid postnatal growth and slow regression during childhood. It may cause confusion with venous malformations that are often incorrectly called “cavernous hemangioma”. Venous malformations comprise abnormally formed channels that are lined by quiescent endothelium. Accurate diagnosis is required for selecting the appropriate treatment

Modified uniportal video-assisted thoracic surgery in children

Video-assisted thoracic surgery (VATS) has been traditionally performed by a multi-port approach, but uniportal VATS is gaining popularity among thoracic surgeons. The use of only one intercostal space may result in less pain, but competition among camera and operating instruments may be a disadvantage. In children, the limited space in the thorax makes the uniportal VATS difficult to accomplish. We present a modification of the uniportal VATS, using a single skin incision but placing the thoracoscope in the superior or inferior intercostal space relative to the working instruments to increase instrument range of motion within a single intercostal space

Single-Incision Pediatric Endosurgery (SIPES) oophoropexy in an adolescent with Hodgkin lymphoma prior to pelvic irradiation

Oophoropexy for fertility preservation during pelvic irradiation dates back to the mid-1960s. For Hodgkin lymphoma (HL), this was performed during a staging laparotomy. Laparoscopic ovarian fixation has supplanted open pexy with advancements in technology and abandonment of staging laparotomies. Single-Incision Pediatric Endosurgery (SIPES) is applicable to numerous multi-port operations. Use of this technique for oophoropexy prior to pelvic irradiation, however, has not been reported. A 19 year-old with stage IVb HL involving the left iliac node basin was to receive radiotherapy and was evaluated for bilateral oophoropexy. An Olympus TriPort™ was introduced at the umbilicus, through which a 5 mm zero-degree laparoscope and a needle driver were introduced. Transabdominal passage of a ski needle through a 2 mm nick in the skin of the anterolateral wall allowed for right sided fixation of the ovaries. Operative recovery was uncomplicated, and post-operative imaging demonstrated satisfactory positioning of the gonads outside the planned radiation field. In conclusion, SIPES oophoropexy is a technically simple method for fertility preservation that offers improved cosmesis
