Stereotactic Irradiation of GH-Secreting Pituitary Adenomas

International Journal of Endocrinology, 2012
Radiotherapy (RT) is often employed in patients with acromegaly refractory to medical and/or surgical interventions in order to prevent tumour regrowth and normalize elevated GH and IGF-I levels. It achieves tumour control and hormone normalization up to

Intrafraction motion and impact of margin reduction for MR‐Linac online adaptive radiotherapy for pancreatic cancer treatments

Journal of Medical Radiation Sciences, Volume 72, Issue 1, Page 17-24, March 2025.
This analysis included quantification of intrafraction motion in pancreas stereotactic ablative radiotherapy treated on the MR‐Linac, leading to the development of adjusted (PTV) margins. Intrafraction motion indicated an average target displacement of 1–3 mm, resulting in an adjusted PTV margin of 2 mm in the right–left and superior–inferior ...

Hypofractionated Stereotactic Radiotherapy after Transarterial Chemoembolisation Failure in an Unresectable Hepatocellular Carcinoma: A Case Presentation

Case Reports in Hepatology, 2013
Introduction. Transarterial chemoembolization is the first-line treatment in unresectable hepatocellular carcinoma. There is no standard treatment after transarterial chemoembolization failure. We report the case of a patient with advanced hepatocellular

CyberKnife Stereotactic Radiosurgery System for Pituitary Tumors and Pulmonary Cancer Bone Metastases: Initiating a New Chapter in Stereotactic Radiotherapy

Xiehe Yixue Zazhi
The CyberKnife, an acronym for the stereotactic radiosurgery platform, represents an image-guided stereotactic radiotherapy technique. This technology precisely delivers ionizing radiation to tissues, effectively damaging tumor cells, and is suitable for

Boost Approaches in Patients Undergoing Postoperative Radiotherapy

Journal of Surgical Oncology, EarlyView.
ABSTRACT The use of breast conservation surgery for early‐stage breast cancer is common, and adjuvant radiotherapy is often recommended to reduce the risk of ipsilateral breast tumor recurrence. Historical trials have used sequential boost techniques with favorable outcomes with reduction in local recurrence and acceptable cosmetic outcomes.

Stereotactic radiosurgery and stereotactic radiotherapy for brain metastases

Surgical Neurology International, 2013
Stereotactic radiosurgery (SRS) and hypofractionated stereotactic radiotherapy (HFSRT) have become important treatment modalities for brain metastases. While effective, there are still areas of extensive debate on its appropriate use in patients with life-limiting diseases.

Identification of Predictive Factors for Isolated Brain Progression in Patients With Cerebral Metastatic Melanoma After Treatment With Stereotactic Brain Radiotherapy

JEADV Clinical Practice, EarlyView.
ABSTRACT Background Melanomas often metastasize to the brain, leading to a significantly poor prognosis despite advances in local and systemic treatments. In clinical practice, we frequently observe varying response patterns and progression dynamics between cerebral and extra cerebral sites. Objectives This study aims to identify predictive factors for

RTA‐408 Enhances Radiosensitivity and Inhibited Tumor Progression via JNK Pathway in Glioblastoma

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Glioblastoma (GBM) is an aggressive brain tumor with poor prognosis owing to its high invasiveness and resistance to therapy. RTA‐408, a synthetic triterpenoid and nuclear factor erythroid 2‐related factor 2 activator, exhibits anti‐inflammatory and anti‐cancer properties; however, its effects on GBM remain unclear. This study investigated the
