Variations in linear energy transfer distributions within a European proton therapy planning comparison of paediatric posterior fossa tumours.

Background And Purpose: Radiotherapy for paediatric posterior fossa tumours may cause complications in the brainstem and upper spinal cord due to high doses. With proton therapy (PT) this risk may increase due to higher relative biological effectiveness (RBE) from elevated linear energy transfer (LET). This study assesses variations in LET in the brainstem and spinal cord in proton treatment plans from European centres.

Real-World Evidence of the Impact of CanAssist Breast on Physician's Decision About the Use of Adjuvant Chemotherapy in Early Breast Cancer.

Background Clinicians use prognostic biomarker/multi-gene-based tests for predicting recurrence in hormone receptor-positive/HER2-negative (HR+/HER2-) early-stage breast cancer (EBC). CanAssist Beast (CAB) uses the expression of five protein biomarkers in combination with tumor-specific parameters such as tumor size, histopathological grade, and lymph node status to predict the risk of distant recurrence within five years of diagnosis for patients with HR+/HER2-, EBC. The current study aimed to evaluate the impact of prognostic tests on adjuvant chemotherapy decisions by assessing the agreement between clinical and CAB risk stratification as low-risk (LR) or high-risk (HR) for distant recurrence.

Construction and evaluation of the prediction model for advanced disease in well-differentiated colorectal neuroendocrine neoplasms less than 2 cm in diameter.

Objective: Advanced lesions are often ignored in well-differentiated colorectal neuroendocrine neoplasms (NENs) smaller than 2 cm, and we aimed to develop an effective nomogram for these lesions.

Methods: We extracted data from the Surveillance, Epidemiology, and End Results (SEER) database and used a logistic regression model to identify independent risk factors for advanced disease. All these identified factors were included to construct the prediction model, and the receiver operating characteristic (ROC) curve, calibration plot and DCA curve were utilized to assess the predictive value.

Giant Granular Cell Tumor of the Left Thigh, a Rare Case Report and Literature Review.

Background: Granular cell tumor (GCT) is a rare soft tissue tumor characterized by Schwann cell differentiation. While GCT can occur in any part of the body, it is less common in the lower limbs. We report a case of a giant atypical GCT located in the left thigh, the tumor was initially small and painless at the time of discovery but gradually grew to 17 cm over a two-year period.

Endoureteral ablation: A novel technique to occlude the ureter in patients with urinary tract fistulae.

Urinary fistulae are abnormal connections between the urinary system and adjacent body parts, often resulting from factors such as infection, radiation, malignancy, protracted labor, gynecologic surgery, and gastrointestinal tract surgery. These fistulae can lead to persistent urinary incontinence, skin breakdown, social humiliation, psychosocial trauma, and severe infections. Current treatments include surgical repair, urinary diversion, and ureteral embolization, though these can have complications and are not always successful or feasible for all patients.

Editorial: Precision Medicine in Spinal Oncology.

This special focus issue from the 2023-2024 AOSpine Knowledge Forum Tumor represents a culmination of years of experience devoted to advancing the care of patients with both metastatic and primary spinal tumors. We have learned much since the fundamental assessments of instability that led to the Spinal Instability Neoplastic Score (SINS), the grading of epidural disease utilizing the Epidural Spinal Cord Compression Scale (aka Bilsky grade), as well as the development of tumor-specific health related quality of life assessments such as the Spine Oncology Study Group Outcome Questionnaire (SOSGOQ). These tools have enabled us to make several prior recommendations for the appropriate use of advanced surgical techniques such as en bloc resection and the use of stereotactic body radiotherapy (SBRT) to optimize patient care.
