Longitudinal analysis of cognitive function in patients treated with postoperative radiotherapy for grade 2 and 3 IDH mutant diffuse glioma.

Background: Postoperative radiotherapy and chemotherapy improve survival in IDH mutated diffuse glioma. We investigated whether neurocognitive function declines over time, and whether mean dose to the brain outside of CTV (mean brain dose) is related to neurocognitive function.

Patients And Methods: Patients that underwent resection and postoperative radiotherapy for grade 2 or 3 IDH mutated diffuse glioma were tested using the Hopkins Verbal Learning Test, Letter Fluency and Trail Making Test before surgery and afterwards up until disease progression.

Evaluation of artificial intelligence-based autosegmentation for a high-performance cone-beam computed tomography imaging system in the pelvic region.

Background And Purpose: A novel ring-gantry cone-beam computed tomography (CBCT) imaging system shows improved image quality compared to its conventional version, but its effect on autosegmentation is unknown. This study evaluates the impact of this high-performance CBCT on autosegmentation performance, inter-observer variability, contour correction times and delineation confidence, compared to the conventional CBCT.

Materials And Methods: Twenty prostate cancer patients were enrolled in this prospective clinical study.

The added value of a new high-performance ring-gantry CBCT imaging system for prostate cancer patients.

Background And Purpose: A novel Cone-Beam Computed Tomography (CBCT) named HyperSight provides superior CBCT image quality compared to conventional ring gantry CBCT imaging, and it is suitable for dose calculations for prostate cancer, but it comes with considerable additional costs. The aim of this study was to determine the added value of HyperSight CBCT imaging compared to conventional CBCT imaging in terms of organ visibility in the male pelvic region.

Materials And Methods: Twenty prostate cancer patients were included in this prospective clinical study.

Audit of laparoscopic surgery for colon cancer in Morocco: A report of the results of a prospective multicentre cohort study.

Background: Little data is available about colon laparoscopic surgery in low mid-income countries. The aim of this study was to audit the status and results of laparoscopic colon cancer surgery in Morocco.

Patients And Methods: This was a prospective study performed at 4 academic departments in Morocco between January 1, 2018, and March 31, 2020.
