Mullerian dysgenesis: a critical review of the literature

Purpose: To present an update of the genetic, clinical, diagnostic, and therapeutic aspects of Mayer–Rokitansky–Kuster–Hauser (MRKH) syndrome. Methods: Studies were considered eligible if they have evaluated patients with MRKH syndrome. Eligible articles were identified by a search of MEDLINE bibliographical database from 1950 to August 2016. A purely descriptive approach was adopted concerning all outcomes examined by the individual studies. Results: MRKH syndrome is defined as congenital aplasia of the upper vagina and impairment of uterine development in normal 46XX females. Accounting for 1:4500 women, MRKH is the second most common cause of primary amenorrhea following gonadal dysgenesis. Potential association of MRKH syndrome to specific genes has been the focus of recent research. Null-association results of HOXA genes and Wnt5a, Wnt7a, and Wnt9a have been reported, while point mutations of the WNT4 gene point mutations have been associated with an MRKH-like syndrome characterized by Mullerian duct regression and hyperandrogenism. Ultrasound and Magnetic Resonance Imaging (MRI) are the main techniques to establish an accurate diagnosis of the syndrome. Several non-surgical and surgical procedures have been reported for the creation of a functional neovagina; in general, non-surgical treatment should be the first initially pursued. Along with psychological support, recent developments in assisted reproductive technologies of IVF techniques and the availability of gestational surrogacy, as well as the recent breakthrough of successful uterus transplantation, enable women with MRKH syndrome to attain their own genetic child. Conclusion(s): MRKH syndrome is a medical modality with important social, legal, and ethical projections that require a multi-disciplinary approach. © 2017, Springer-Verlag Berlin Heidelberg

A population-based analysis of a rare oncologic entity: Malignant pancreatic tumors in children

Purpose: To examine the clinicopathological characteristics and prognosis of pediatric patients with malignant pancreatic tumors in a population-based cohort. Methods: The Surveillance, Epidemiology, and End Results (SEER) database was utilized to identify all pediatric patients with malignant pancreatic tumors, diagnosed between 1973 and 2013. Kaplan–Meier analysis was performed to determine median and five-year overall survival (OS) rates. Univariate survival analysis was executed using the log-rank test. Cox proportional hazards model was used to identify variables independently associated with mortality. Results: A total of 114 patients with pancreatic malignancies were identified. Median patient age was 16 years and the majority of patients were white (64%) females (61.4%). The most prevalent histologic subtype was neuroendocrine tumors (35.1%), whereas pancreatoblastoma was more common during the first decade of life (P < 0.001). Distant metastases were noted in 41.7% of the patients, while 33.3% and 25% had localized and regional disease respectively. Five-year OS rates were 77%, 66.4% and 64.8% for patients with pancreatoblastoma, neuroendocrine and epithelial tumors respectively. No death was observed in the solid pseudopapillary tumor group. Only history of having cancer-directed surgery (CDS) was significantly associated with lower overall mortality (HR: 5.1, 95% CI: 2.1, 12.4). Conclusion: Pancreatic malignancies are rare in children. Their prognosis is variable and only CDS was independently associated with superior survival. Evidence rating/classification: Prognosis study, Level II. © 2017 Elsevier Inc

Solid pseudopapillary and malignant pancreatic tumors in childhood: A systematic review and evidence quality assessment

A systematic review of 32 studies reporting on 489 children with pancreatic tumors was performed. The most prevalent histologic subtype was solid pseudopapillary tumor (SPT) (61.3%). Pancreaticoduodenectomy was the most commonly performed operation (48%). Neoadjuvant chemo/radiotherapy was utilized in 3.9, 36.2, 25, and 27.8% of patients with SPTs, pancreatoblastomas (PBLs), neuroendocrine tumors, and exocrine carcinomas, respectively. Adjuvant chemotherapy (75.6%) and radiation (34%) were most commonly utilized in PBLs. All-cause mortality was highest in exocrine carcinomas (50%). Overall, 98.8% of patients with SPTs survived. PBL exhibited the highest recurrence rate (14.7%) within a mean of 23.5 months. © 2018 Wiley Periodicals, Inc
