Large language model-augmented learning for auto-delineation of treatment targets in head-and-neck cancer radiotherapy.
Radiother Oncol
January 2025
Department of Radiation Oncology, Stanford University, Stanford, CA, United States. Electronic address:
Background And Purpose: Radiation therapy (RT) is highly effective, but its success depends on accurate, manual target delineation, which is time-consuming, labor-intensive, and prone to variability. Despite AI advancements in auto-contouring normal tissues, accurate RT target volume delineation remains challenging. This study presents Radformer, a novel visual language model that integrates text-rich clinical data with medical imaging for accurate automated RT target volume delineation.

Centre for Medical and Radiation Physics, University of Wollongong, NSW, Australia; St George Cancer Care Centre, St George Hospital, Kogarah, NSW, Australia; School of Physics, University of Sydney, Camperdown, NSW, Australia.
Purpose: Even with modern immobilisation devices, some amount of intrafraction patient motion is likely to occur during stereotactic radiosurgery (SRS) delivery. The aim of this work was to investigate how robustness of plans to intrafraction motion is affected by plan geometry and complexity.
Methods: In 2018, the Trans-Tasman Radiation Oncology Group conducted a multiple-target SRS international planning challenge, the data from which was utilised in this study.
Molecular classification of endometrial cancers (EC) and association with relapse-free survival (RFS) and overall survival (OS) outcomes: Ancillary analysis of GOG-0258.
Gynecol Oncol
January 2025
Duke University, Durham, NC, United States of America. Electronic address:
Purpose: Determine if molecular classification using mismatch repair (MMR) and p53 protein expression predicts recurrence-free survival (RFS) and overall survival (OS) in endometrial cancer (EC) patients treated with chemotherapy and radiation (CRT) versus chemotherapy (CT).
Methods: GOG-0258, a phase III randomized trial (NCT00942357), compared CRT to CT. Immunohistochemistry assessed MMR and p53 status.
Endocrine Outcome and Quality of Life After Transsphenoidal Resection of Pituitary Adenoma-A Prospective Randomized Single-Blinded Study Comparing Endoscopic Versus Microscopic Resection.
Neurol Int
January 2025
Department of Neurosurgery, University of Ulm, Lindenallee 2, 89312 Günzburg, Germany.
Background: Endoscopic pituitary surgery might yield better endocrine outcomes compared to microscopic resection. We conducted a prospective, randomized, single-blinded study to compare the endocrine outcome and quality of life (QoL) of patients with newly diagnosed pituitary adenoma who underwent either endoscopic or microscopic transsphenoidal surgery (NCT03515603).
Methods: Due to slow recruitment, this study had to be stopped prematurely.
Dominant Occipital Sinus: A Rare Anatomical Variant With Potentially Catastrophic Consequences if Unrecognized Preoperatively.
Cureus
December 2024
Department of Neurosurgery, Southmead Hospital, North Bristol NHS Trust, Bristol, GBR.
The occipital sinus is often thought of as a redundant vestigial structure in adults. However, in rare cases, it can form the dominant route of intracerebral venous drainage, with a risk of significant surgical morbidity if unrecognised. We present an illustrative case describing this anatomical variant and tailoring of a midline suboccipital craniotomy to allow resection of a fourth ventricular epidermoid tumour with preservation of a dominant occipital sinus, and a review of the published literature.
