Associations of Microvascular Risk Factors with Sporadic Vestibular Schwannoma Outcomes Following Stereotactic Radiosurgery.

Objective: Stereotactic radiosurgery (SRS) is increasingly used for small-to-medium-sized sporadic vestibular schwannoma (VS) and is associated with good tumor control and low-risk of adverse radiation-associated events. The exact mechanism of VS tumor control is unknown but may relate to microvascular hyalinization and resultant tumoral ischemia. This study examined associations of microvascular risk factors with outcomes following SRS.

Long-Term Prospective Quality-of-Life Outcomes in 445 Patients with Sporadic Vestibular Schwannoma.

Objective: To evaluate the long-term changes in sporadic vestibular schwannoma (VS) disease-specific quality-of-life (QOL) outcomes.

Study Design: Prospective longitudinal study using the Penn Acoustic Neuroma Quality of Life (PANQOL) Scale.

Setting: National survey.

Vestibular schwannoma-related increased labyrinthine post-gadolinium 3D-FLAIR signal intensity and association with hearing impairment.

Background And Purpose: Vestibular schwannomas (VSs) are benign neurogenic tumors commonly associated with progressive unilateral hearing loss, tinnitus, and vestibular symptoms. Growing evidence links signal changes in the VS-adjacent labyrinth with sensorineural hearing loss. This study seeks to quantify the association of labyrinthine signal on post-gadolinium 3D-FLAIR imaging correlates with hearing loss and to evaluate potential longitudinal changes over time.

Evaluation of American Urological Association Renal Cell Carcinoma Risk Groups for Chromophobe Renal Cell Carcinoma.

Objective: To develop and compare various models for risk stratification in chromophobe renal cell carcinoma (chrRCC). Models have been developed to predict progression-free (PFS) and cancer-specific survival (CSS) following surgery for localized renal cell carcinoma (RCC). Notably, chromophobe RCC (chrRCC) is not included in American Urological Association (AUA) risk stratification, as nuclear grading is not recommended.

Incidence and predictors of ipsilateral local recurrence following partial nephrectomy.

Purpose: Ipsilateral local recurrence (LR) after partial nephrectomy (PN) for renal cell carcinoma (RCC) may result from a metachronous tumor or PN bed recurrence. To date, literature has predominantly reported ipsilateral LRs collectively, although the pathophysiology and prognostic implications of these event may be distinct. We sought to assess variables associated with LR and evaluated associations of LR with metastasis and death from RCC.

End-Stage Kidney Disease After Partial and Radical Nephrectomy Among Patients With Severe Chronic Kidney Disease.

Purpose: AUA guidelines prioritize nephron sparing in patients with preexisting chronic kidney disease (CKD). However, few studies analyze long-term renal function in patients with preoperative severe CKD who undergo extirpative renal surgery. Herein, we compare the hazard of progression to end-stage kidney disease (ESKD) following partial nephrectomy (PN) and radical nephrectomy (RN) among patients with preoperative severe CKD.

Multi-center study on sellar reconstruction after endoscopic transsphenoidal pituitary surgery.

Introduction: Surgical techniques for sellar reconstruction include no reconstruction, use of synthetic materials, autologous grafts, and/or vascularized flaps. The aim of this study was to conduct a multi-center study comparing the efficacy and postoperative morbidity associated with different sellar reconstruction techniques.

Methods: A retrospective chart review of patients who underwent endoscopic transsphenoidal surgery for pituitary tumors from five participating sites between January 2021 and March 2023 was performed.

Mayo Clinic Validation of the AUA Risk Groups for Localized Renal Cell Carcinoma.

Purpose: The AUA guidelines introduced a new risk group stratification system based primarily on tumor stage and grade to guide surveillance for patients treated surgically for localized renal cell carcinoma (RCC). We sought to evaluate the predictive ability of these risk groups using progression-free survival (PFS) and cancer-specific survival (CSS), and to compare their performance to that of our published institutional risk models.

Materials And Methods: We queried our Nephrectomy Registry to identify adults treated with radical or partial nephrectomy for unilateral, M0, clear cell RCC, or papillary RCC from 1980 to 2012.

Repeat Radiosurgery for Sporadic Vestibular Schwannoma After Primary Radiosurgical Failure: An International Multi-institutional Investigation.

Objective: To describe outcomes of patients with sporadic vestibular schwannoma (VS) who underwent repeat stereotactic radiosurgery (SRS) after primary SRS failure.

Study Design: Multi-institutional historical cohort study.

Setting: Five tertiary care referral centers.

Current practices and opinions on auditory training in adult cochlear implant recipients.

Objective: To examine current practices and opinions of cochlear implant (CI) providers with respect to post-implantation auditory training.

Methods: A survey was submitted to the American Cochlear Implant Alliance membership that reviewed current practice and opinions with respect to post-implantation auditory training for adult CI recipients.

Main Outcome Measures: Review of respondent practice, center volume, role on CI team, and current usage and opinions surrounding auditory training, including resources used and schedule of use.

Salvage Microsurgery Following Failed Primary Radiosurgery in Sporadic Vestibular Schwannoma.
