Objective: To investigate the therapeutic outcome and prognostic factors in patients with non-metastatic esophageal carcinoma.
Methods: Between January 1989 and December 2003, 171 patients with non-metastatic esophageal carcinoma patients were retrospectively assessed in the Department of Radiation and Oncology, Institute of Oncology, Turkey.
Results: The distribution of the stage at presentation designated 39 stage II patients (23%) and 132 stage III patients (77%). The primary tumors were treated with surgery and postoperative radiotherapy (RT) in 29 patients (17%), with surgery, postoperative RT and chemotherapy (CT) in 17 patients (10%), with radical RT in 40 patients (23%), and with RT and CT in 47 patients (27%). Fourteen patients (8%) did not receive any postoperative adjuvant treatment. Two and three-year survival rates of the whole group were 27.0% and 14.8%, respectively. Clinical staging was the only statistically significant prognostic factor by multivariate analyses (p=0.04). Median survivals by the treatment groups were 12.5 months for surgery alone, 16 months for surgery plus postoperative RT, 15 months in surgery plus postoperative chemoradiotherapy, 9 months in radical RT alone and 17 months in chemoradiotherapy group. Survival advantage was not demonstrated for postoperative RT or RT plus CT. Outcomes were similar between the patients treated with surgery and with chemoradiotherapy (p=0.54). Patients treated with chemoradiotherapy had a longer survival than patients treated with only RT (p=0.05).
Conclusion: The most important prognostic factor was the stage of the disease. Survival advantage was not demonstrated for postoperative RT or RT plus CT. Outcomes were similar between patients treated by surgery and by chemoradiotherapy.

Objective: The extent of resection (EOR) is an important prognostic factor for both low- and high-grade gliomas. Intraoperative MRI (iMRI) has been used to increase the EOR in glioma surgery. While a recent study reported differences between iMRI and early postoperative MRI (epMRI), their specific relationship to postoperative clinical symptoms remains unclear.

Objective: Periventricular anastomosis (PA), a recently recognized cause of hemorrhage in moyamoya disease, is reducible after bypass surgery. The timing of the reduction, however, remains poorly understood. The objectives of the present study were to demonstrate radiological reduction of PA occurring within 48 hours after surgery and to identify factors associated with reduction.

Introduction: Following liver transplantation (LT), adequate nutrition is essential, as malnutrition may contribute to slower growth in pediatric patients and put patients at risk of complications following transplant. Avoidant Restrictive Food Intake Disorder (ARFID) is an eating disorder characterized by restrictive eating patterns that compromise nutrition. Patients with ARFID may have significant difficulty meeting nutritional needs due to fear of gastrointestinal distress, making it especially difficult to manage in patients following LT.

Introduction: Given the risks of cardiovascular disease among pediatric kidney transplant recipients, we evaluated whether there was an association between rapid weight gain (RWG) following kidney transplantation and the development of obesity and hypertension among children enrolled in the North American Pediatric Renal Trials and Collaborative Studies (NAPRTCS) registry.
Methods: This retrospective analysis of the NAPRTCS transplant cohort assessed for RWG in the first year post-transplant and evaluated for obesity and hypertension in children with and without RWG up to 5 years post-transplant. We evaluated three separate eras (1986-1999, 2000-2009, and 2010-2021).

Pediatric liver transplantation (PLT) is a life-saving procedure for children with end-stage liver disease. However, post-transplant monitoring, particularly the diagnosis and prognosis of complications such as allograft fibrosis, remains challenging. Traditionally, liver biopsy has been the gold standard for assessing allograft fibrosis, despite its invasive nature and inherent procedural risks.
