Clinicogenomic Features and Outcomes of Adenoid Cystic Carcinoma With Central Nervous System Metastases: A Single‐Institution Cohort Study

Head &Neck, EarlyView.
ABSTRACT Background Adenoid cystic carcinoma (ACC) is a rare malignancy with a propensity for perineural invasion and hematogenous spread. Central nervous system (CNS) involvement is uncommon, and detailed clinical and genomic data on this aspect of the disease remain limited.

Comparison of Six‐ and Three‐Dimensional Error Corrections for the Planning Target Volume in Patients With Nasopharyngeal Cancer

Journal of Medical Radiation Sciences, EarlyView.
6D correction for CBCT achieves better dose coverage of target tumour volume than 3D correction in patients with nasopharyngeal carcinoma. 6D correction significantly improved the dose coverage of PTV‐low at 5 weeks after treatment as compared to 3D correction.

Is Proton Therapy Superior to Gamma Knife Radiosurgery for Sporadic Vestibular Schwannoma?

The Laryngoscope, EarlyView.
With changing practice patterns, radiation therapy for vestibular schwannomas has become an increasingly utilized treatment modality with high tumor control rates. Gamma‐Knife radiosurgery remains a well‐established and readily accessible option with good rates for tumor control, cranial nerve preservation, and hearing outcomes.

Factors associated with the use of salvage whole brain radiation therapy versus salvage stereotactic radiosurgery after initial stereotactic radiosurgery for brain metastases

, 2022
ObjectivesPatients undergoing stereotactic radiosurgery (SRS) for brain metastases require additional radiation for relapse. Our objective is to determine the factors associated with salvage SRS versus whole brain radiation therapy (WBRT) for salvage of ...
