AO Spine Knowledge Forum Tumor at the GSC 2022 in Las Vegas

AO Spine KF Tumor at the Global Spine Congress 2022 in Las Vegas, NV, US

AO Spine Knowledge Forum (KF) Tumor is an international group of dedicated spine oncology surgeons and oncologists who:

implement physician-driven landmark clinical studies;
advance patient care through multicenter analysis and peer-reviewed publications;
focus on both metastatic and the very rare primary spine tumors.

Ongoing research projects

Patient Expectations and Perceptions in Spinal Oncology (PEPSO)

Publication summary
* Metastatic Tumor Research and Outcomes Network (MTRON)

A multicenter prospective registry for the management and outcomes of metastatic spine tumors

Principal investigator:

Charles Fisher

Co-Principal investigators:

Arjun Sahgal, Ilya Laufer

Goals:

Aims to establish a network of spine oncology centers dedicated to prospective multicenter international research of patients diagnosed with metastatic tumors of the spine and will include a comprehensive prospective clinical database which will serve as a shared research platform. The association of clinical, diagnostic, and therapeutic variables with patient reported outcomes, morbidity data, local tumor control, and survival will be investigated.

** Primary Tumor Retrospective (PT Retro)

Predictors of mortality and morbidity in the surgical management of primary tumors of the spine: a multi-center retrospective cohort study with a cross-sectional survival check

Principal investigator:

Charles Fisher

Co-Principal investigators:

Ziya Gokaslan

Goals:

Determined what variables (clinical, diagnostic, therapeutic, or demographic) are associated with local recurrence and survival within defined groups of primary malignant and benign bone and soft tissue spine tumors
i. Overall analysis – analysis of the complete collection
ii. Histotype analysis – analysis of each tumor histotype. Each histotype (13 identified) will undergo a separate analysis by assigned project members

ClinicalTrials.gov Identifier: NCT01643174
TERT (an extension of PT Retro)

An analysis of the role of the TERT promoter mutations in retrospectively collected primary spinal column tumors

Principal investigator:

Chetan Bettegowda

Co-Principal investigators:

Ziya Gokaslan

Goals:

Determined the rates of TERT promoter mutation (mutation of the promoter of the telomerase gene
[23348506,23348503]) and its prognostic significance in primary spinal column tumors

Documents:

Publication summary
FFPE Chordoma (an extension of PT Retro)

FFPE=Formalin-Fixed Paraffin-Embedded tissue. An analysis of the role of the single nucleotide polymorphism rs2305089 in retrospectively collected chordomas

Principal investigator:

Chetan Bettegowda

Co-Principal investigators:

Stephen Yip

Goals:

Aimed to determine the role that the SNP rs2305089 has in the prognosis of chordoma patients by evaluating whether there is a relationship between the status of the SNP and various clinical outcomes/measures (eg, survival, local recurrence, response to radiation therapy, response to chemotherapy, link to metastasis, demographics)

Documents:

Publication summary
Systematic Reviews
Systematic reviews about the outcomes of surgical treatment of metastases to the spine and primary tumors of the spine

Principal investigator:

Performed a systematic review of the literature for prognostic factors specific to:
i. surgical treatment of prostate metastases to the spine
ii. surgical treatment of breast metastases to the spine
iii. surgical treatment of renal cell metastases to the spine
iv. surgical treatment of lung metastases to the spine
v. symptomatic vertebral hemangioma
