Prognostic value of manual versus automatic methods for assessing extents of resection and residual tumor volume in glioblastoma.
J Neurosurg

Objective: The extent of resection (EOR) and postoperative residual tumor (RT) volume are prognostic factors in glioblastoma. Calculations of EOR and RT rely on accurate tumor segmentations. Raidionics is an open-access software that enables automatic segmentation of preoperative and early postoperative glioblastoma using pretrained deep learning models.

Universidade Estadual de Campinas, Faculty of Medical Sciences, Department of Surgery, Digestive Diseases Surgical Unit - Campinas (SP), Brazil.
Background: Gastric stump neoplasia is defined as a neoplasia that arises in the gastric remnant after at least 5 years of interval from the first gastric resection.
Aims: The aim of this study was to analyze 51 patients who underwent total and subtotal gastrectomy and multi-visceral resections in patients with gastric stump cancer.
Methods: The hospital records of 51 patients surgically treated for gastric stump cancer between 1989 and 2019 were reviewed.
Comparative analysis of treatment modalities for pediatric spinal cord glioblastoma: insights from a meta-analysis.

Introduction: Glioblastomas (GBM) are aggressive tumors that make up about 7% of central nervous system tumors in children. Spinal GBMs (sGBMs) are extremely rare, accounting for less than 1% of pediatric spinal tumors. sGBMs are difficult to treat due to their infiltrative nature and cause significant morbidity.

Department of Gastroenterological Surgery and Pediatric Surgery, Gifu University Graduate School of Medicine, 1-1 Yanagido, Gifu City, Gifu Prefecture, 501-1194, Japan.
Background: Complex surgery during initial cancer treatment can limit surgical options when planning management of a secondary malignancy. Subtotal esophagectomy and pancreatoduodenectomy are the most invasive and difficult procedures in gastroenterological surgery. Surgical cases in which subtotal esophagectomy was performed after pancreatoduodenectomy with pancreaticogastrostomy are extremely rare and challenging procedures due to the resulting complicated anatomical changes.

Target populationAdults with imaging suggestive of a WHO grade II diffuse gliomas (oligodendrogliomas or astrocytomas)QuestionIn adults with imaging suggestive of a WHO grade II diffuse gliomas (oligodendrogliomas or astrocytomas), does surgical resection improve overall survival compared to observation or biopsy?Updated Recommendation from the Prior Version of These Guidelines:Level III: In adults with imaging suggestive of a WHO grade II diffuse gliomas (oligodendrogliomas or astrocytomas), surgical resection is suggested over observation or biopsy to improve overall survival.Question Q2In adults with imaging suggestive of a WHO grade II diffuse gliomas (oligodendrogliomas or astrocytomas), does maximal surgical resection improve progression free survival (PFS) and overall survival (OS) compared to subtotal resection/biopsy?Unchanged Recommendations from the Prior Version of These GuidelinesLevel II It is recommended that GTR or STR be accomplished instead of biopsy alone when safe and feasible so as to decrease the frequency of tumor progression recognizing that the rate of progression after GTR is fairly high.Level III Greater extent of resection can improve OS in WHO grade II diffuse gliomas patients.
