Sternal cleft is a chest wall malformation that can expose mediastinal viscera and vessels to injuries. It can be classified into two forms, complete and partial. Its etiology and incidence are unknown and it is often associated with other defects. The aim of this article is to review the literature and report our experience with this rare anomaly, focusing on clinical presentation and management. We reviewed the English written literature about sternal cleft and collected the clinical data of all the published series. We present seven new cases that we have observed and treated since 1999. Literature reports 51 series including 86 patients, more frequently female (62%) and affected with partial superior form (67%). Sternal cleft is often asymptomatic (74%) and associated with other defects (72%). Surgical treatments include primary closure (73%), bone graft interposition (10%), prosthetic closure (7%), and muscle flap interposition (3%). In our series, primary closure was possible in four cases, while in three cases we placed a prosthesis. Five patients had associated defects and two were affected with PHACES (posterior fossa abnormalities, hemangiomas, arterial lesions, cardiac abnormalities/aortic coarctation, abnormalities of the eye, and sternum defects) syndrome. We report for the first time the association of sternal cleft with connectival nevi in three of our patients. At follow-up, we observed no major complication or recurrences. Although primary closure is the preferred option and should be performed in the neonatal period, the use of prostheses warrants good results as well. Prior to treatment, associated defects and syndromes should be excluded.

The unchanged IDRF pattern in 50% of patients and the appearance of new IDRF during chemotherapy in approximately 20% of patients strengthens the idea that prolonged chemotherapy is useless for improving surgical resection in this population of patients. In addition, midline perivascular abdominal preoperative IDRF appeared to be predictive not only of surgical outcomes but also of EFS and OS.

Listen to the podcast by Dr Irwin at www.jco.org/podcastsThe International Neuroblastoma Response Criteria (INRC) require serial measurements of primary tumors in three dimensions, whereas the Response Evaluation Criteria in Solid Tumors (RECIST) require measurement in one dimension. This study was conducted to identify the preferred method of primary tumor response assessment for use in revised INRC. Patients and MethodsPatients younger than 20 years with high-risk neuroblastoma were eligible if they were diagnosed between 2000 and 2012 and if three primary tumor measurements (antero-posterior, width, craniocaudal) were recorded at least twice before resection. Responses were defined as $ 30% reduction in longest dimension as per RECIST, $ 50% reduction in volume as per INRC, or $ 65% reduction in volume.Results Three-year event-free survival for all patients (N = 229) was 44% and overall survival was 58%. The sensitivity of both volume response measures (ability to detect responses in patients who survived) exceeded the sensitivity of the single dimension measure, but the specificity of all response measures (ability to identify lack of response in patients who later died) was low. In multivariable analyses, none of the response measures studied was predictive of outcome, and none was predictive of the extent of resection. ConclusionNone of the methods of primary tumor response assessment was predictive of outcome. Measurement of three dimensions followed by calculation of resultant volume is more complex than measurement of a single dimension. Primary tumor response in children with high-risk neuroblastoma should therefore be evaluated in accordance with RECIST criteria, using the single longest dimension.

Laparoscopy proved to be feasible, safe and effective for the treatment of IBD in children. Although we observed a relatively low incidence of complications, stoma site adhesions still remain the major issue, which can be effectively dealt with laparoscopically. Functional outcome as well as cosmesis is satisfactory. As results are encouraging, at present we prefer laparoscopy for the surgical treatment of IBD in pediatric patients.

Comparing thoracoscopic surgery with the traditional open approach, we confirmed the superiority of minimally invasive treatment in terms of postoperative hospital stay. Common technical recommendations can help pediatric centers to develop the thoracoscopic approach for the treatment of congenital pulmonary malformations.

This initial experience confirms that RS is as safe and effective as conventional MAS. A number of selected procedures performed with RS would only benefit from this approach, as it is not suitable for conventional MAS. Although economically demanding, in particular for a pediatric hospital, we firmly believe that centralization of care would allow pediatric surgeons adopting RS to perform complex reconstructive surgical procedures with great advantages for the patients and a minimal increase in overall costs for the health system.

To create the first structured surgical report form for NBL with international consensus, to permit standardized documentation of all NBLrelated surgical procedures and their outcomes. Summary of Background Data: NBL, the most common extracranial solid malignant tumor in children, covers a wide spectrum of tumors with significant differences in anatomical localization, organ or vessel involvement, and tumor biology. Complete surgical resection of the primary tumor is an important part of NBL treatment, but maybe hazardous, prone to complications and its role in high-risk disease remains debated. Various surgical guidelines exist within the protocols of the different cooperative groups, although there is no standardized operative report form to document the surgical treatment of NBL. Methods: After analyzing the treatment protocols of the SIOP Europe International Neuroblastoma Study Group, Children's Oncology Group, and Gesellschaft fuer Paediatrische Onkologie und Haematologie -German Association of Pediatric Oncology and Haematology pediatric cooperative groups, important variables were defined to completely describe surgical biopsy and resection of NBL and their outcomes. All variables were discussed within the Surgical Committees of SIOP Europe International Neuroblastoma Study Group, Children's Oncology Group, and Gesellschaft fuer Paediatrische Onkologie und Haematologie -German Association of Pediatric Oncology and Haematology. Thereafter, joint meetings were organized to obtain intercontinental consensus. Results: The ''International Neuroblastoma Surgical Report Form'' provides a structured reporting tool for all NBL surgery, in every anatomical region, documenting all Image Defined Risk Factors and structures involved, with obligatory reporting of intraoperative and 30 day-postoperative complications.
