Skull Base Tumors

The NeoScorch HN study is a single institution multisite phase II trial including 3 cohorts of 25 patients each for patients with newly diagnosed locoregionally advanced, histologically confirmed, head and neck cancer eligible for curative-intent treatment, who will receive neo-adjuvant chemoimmunotherapy-based treatment as well as standard of care adjuvant treatment. The three cohorts include three different aspects of surgical de-escalation in head and neck cancer. The first cohort includes human papillomavirus independent (HPV-) squamous cell carcinoma of the head and neck. The second cohort includes HPV-associated head and neck cancer with radiographic evidence of extranodal extension in neck lymphadenopathy. The third cohort specifically includes malignancies of the sinonasal cavity and skull base which have a propensity for invasion of the orbit, skull base, and maxilla. Surgical treatment of all three of these cohorts has significant morbidity including swallowing, speech, and vision among others.

The evaluation of neurosurgical outcomes varies from center to center, and the predictive factors that determine these outcomes are not fully known or shared. This study aims to assess outcomes and their predictors using measures agreed upon by the participating centers. Standardizing the evaluation of outcomes and predictors improves the quality of research, allows for data comparison, and facilitates a "common language" in routine clinical practice. Most importantly, it influences therapeutic decisions in various neurosurgical conditions. Clinically, the identified predictors can also be used during preoperative assessments to provide more precise guidance to patients undergoing surgery.
