Preoperative stereotactic radiotherapy for the management of brain metastases.

Traditionally, postoperative whole-brain radiation therapy (WBRT) has been used for resected brain metastases, reducing local and intracerebral relapses. However, WBRT is associated with cognitive deterioration. Postoperative stereotactic radiotherapy (SRT) has emerged due to its neurocognitive preservation benefits.

The Recent Management of Vestibular Schwannoma Radiotherapy: A Narrative Review of the Literature.

Background: Radiotherapy (RT) plays an important role in the therapeutic management of vestibular schwannoma (VS). Fractionated stereotactic radiotherapy (FSRT) or radiosurgery (SRS) are the two modalities available. The purpose of this article is to review the results of VS RT studies carried out over the last ten years.

Imaging quality of an artificial intelligence denoising algorithm: validation in Ga PSMA-11 PET for patients with biochemical recurrence of prostate cancer.

Background:  Ga-PSMA PET is the leading prostate cancer imaging technique, but the image quality remains noisy and could be further improved using an artificial intelligence-based denoising algorithm. To address this issue, we analyzed the overall quality of reprocessed images compared to standard reconstructions. We also analyzed the diagnostic performances of the different sequences and the impact of the algorithm on lesion intensity and background measures.

Combined intra-cavitary and interstitial image-guided adaptative brachytherapy for cervical stump carcinomas: technical and clinical results of six patients.

Purpose: According to European guidelines for cervix cancers, the management of cervical stump cancers should follow recommendations for patients without previous sub-total hysterectomy, but may require adaptation of radiotherapy modalities, especially brachytherapy (BT). However, data with modern BT technics are very scarce.

Material And Methods: From May 2013 to March 2020, 6 patients (age range, 71-88 years) with cervical stump squamous cell carcinoma (previously treated by sub-total hysterectomy) have been treated with external beam radiotherapy (intensity-modulated radiation therapy - IMRT, 45 Gy in 25 fractions, 5 patients, or 50.

Multiple sclerosis as differential diagnosis of radionecrosis for post-irradiation brain lesions: A case report.

Introduction: Demyelination can occur after brain radiotherapy in tissue adjacent to irradiated tumours. To date, no correlation has been found between conventional-dose radiotherapy and the development of multiple sclerosis, but radiotherapy could be a triggering factor among women with known multiple sclerosis. To the best of our knowledge, this is the first well-documented case of this association with a dosimetric analysis.

Efficacy of pentoxifylline-tocopherol-clodronate in mandibular osteoradionecrosis.

Objectives/hypothesis: PENTOCLO treatment, associating pentoxifylline, tocopherol, and clodronate, resolves radiation-induced fibrosis. The main aim of the present study was to prospectively assess efficacy in mandibular osteoradionecrosis (ORN).

Study Design: Prospective cohort study.
