Summary

The purpose of the study is to analyze biological samples and genetic material for basic science research investigating the molecular and cellular characterization of skull base tumors.

Detailed description

The overall goal of this proposal is to determine new molecular and cellular features that define tumor subtypes that are clinically actionable, may drive important changes in patient management, and/or elucidate novel chemotherapeutic options. Skull base tumors are currently diagnosed based on histopathologic criteria, on which post-operative management is based. However, the investigators hypothesize that each tumor type (eg. chordoma or chondrosarcoma) will have molecular and/or cellular subcategories that will redefine how to categorize and diagnose patients, predict clinical outcome, and optimally design a patient-specific management strategy. In addition, we aim to catalogue changes that occur after treatment after surgical resection, chemotherapy, and/or radiation by comparing primary and recurrent tumors.

Conditions

• Skull Base Neoplasm
• Cellular Pathology

Interventions

Type	Name	Description
OTHER	Observation	Understanding the biology of skull base tumors will teach the investigators about the genesis and/or mechanisms of treatment resistance. The investigators hope to ultimately identify new targets which will add to the armamentarium by which to treat these tumors.
