  • Assessment of Predicted LET and Dosimetry in Relation to Treatment-Related Injury Following Proton Therapy for Primary Pediatric Central Nervous System, Base of Skull, and Malignancies Scottsdale/Phoenix, AZ

    The purpose of this study is to evaluate LET-based modeling as an early and accurate predictor for white-matter changes as identified on MRI and DTI in pediatric patients with primary central nervous system and skull base malignancies following proton beam therapy

  • A Study to Evaluate Endoscopic Endonasal Skull Base Surgery and Pituitary Surgery Quality of Life Rochester, MN

    The objectives of this study are to:

      • Measure the short and long-term overall and nasal-specific quality of life (QOL) impact of patients undergoing Endoscopic Endonasal Skull Base Surgery (EESBS) for pituitary and sellar lesions.
      • Determine the relative difference in QOL impact of EESBS for patients undergoing surgery for functional and nonfunctional pituitary adenomas.
      • Generate baseline data to development and validate a site-specific endoscopic-specific comprehensive QOL for EESBS.
      • Particular tumors of interest include pituitary tumors, Rathke’s cleft cysts, craniopharyngiomas, clival chordomas and chondrosarcomas.
      • Specific QOL aims focus on olfaction (sense of smell), gustation (sense of taste) and nasal function.



  • Patient Adherence and Symptoms During Post-operative Fluid Restriction Protocol After Transsphenoidal Surgery Jacksonville, FL

    The objectives of this study are to survey patients during the post-operative period regarding their experience with fluid restriction including adherence and discomfort, and to document rates of hyponatremia and readmissions in post-operative patients.

    Advances in endonasal, endoscopic transsphenoidal surgical techniques have decreased complications and length of stay for persons undergoing resection of sellar and suprasellar masses  Previous research by investigators now at Mayo (SLS, AQH) has shown that particular interventions including fluid restriction post-operatively decrease patient morbidity (e.g., from hyponatremia) and readmissions while maintaining patient safety. However, the patient perspective on the impact of fluid restriction has not ...
