Stereotactic biopsy for intracranial space occupying lesions: Experience in a referral hospital in Mexico

open access: yesCirugía y Cirujanos, 2021
Background: Stereotactic brain biopsy (SBB) is used for establishing the histological diagnosis of intracranial lesions that are not amenable for a direct surgical approach.

THE HISTORY OF STEREOTACTIC RADIOSURGERY DEVELOPMENT AND ITS ROLE IN THE TREATMENT OF BRAIN METASTASES

open access: yesОпухоли головы и шеи, 2015
Metastases of primary tumors to the brain develop in 20–40 % of cancer patients. Historical information about the origin and development of the stereotactic radiosurgery method are shown, including GammaKnife and CyberKnife.

Innovative perspectives in limbic surgery using deep brain stimulation

open access: yesFrontiers in Neuroscience, 2023
Limbic surgery is one of the most attractive and retaken fields of functional neurosurgery in the last two decades. Psychiatric surgery emerged from the incipient work of Moniz and Lima lesioning the prefrontal cortex in agitated patients.

Feasibility Study of Real-Time Planning for Stereotactic Radiosurgery [PDF]

open access: yesMedical Physics 2013 Mar;40(3):031711, 2013
Purpose: 3D rotational setup errors in radiotherapy are often ignored by most clinics due to inability to correct or simulate them accurately and efficiently. There are two types of rotation-related problems in a clinical setting. One is to assess the affected dose distribution in real-time if correction is not applied and the other one is to correct ...

Automatic Inverse Treatment Planning for Gamma Knife Radiosurgery via Deep Reinforcement Learning [PDF]

open access: yes, 2021
Purpose: Several inverse planning algorithms have been developed for Gamma Knife (GK) radiosurgery to determine a large number of plan parameters via solving an optimization problem, which typically consists of multiple objectives. The priorities among these objectives need to be repetitively adjusted to achieve a clinically good plan for each patient.

Can STEreotactic Body Radiation Therapy (SBRT) Improve the Prognosis of Unresectable Locally Advanced Pancreatic Cancer? Long-Term Clinical Outcomes, Toxicity and Prognostic Factors on 142 Patients (STEP Study)

open access: yesCurrent Oncology, 2023
Aim: The gold standard of care for pancreatic adenocarcinoma is the integrated treatment of surgery and chemotherapy (ChT), but about 50% of patients present with unresectable disease.

Three independent one-dimensional margins for single-fraction frameless stereotactic radiosurgery brain cases using CBCT [PDF]

open access: yes, 2013
Setting a proper margin is crucial for not only delivering the required radiation dose to a target volume, but also reducing the unnecessary radiation to the adjacent organs at risk. This study investigated the independent one-dimensional symmetric and asymmetric margins between the clinical target volume (CTV) and the planning target volume (PTV) for ...

Resección de meningiomas en diferente localización (temporal y sellar) mediante craneotomía única reporte de un caso y revisión de la literatura

open access: yesCirugía y Cirujanos, 2021
Meningiomas are the most frequent extra-axial tumors of the nervous system. Multiple meningiomas are defined as the presence of two or more lesions that appear simultaneously or not, in different intracranial location, without association to ...
