What no one tells you about primary spinal tumors ?!! single referral center experience

الملخص EN

Objectives : Primary spinal tumors arise from the different elements of the central nervous system ; they originate from the spine cord itself and its adjacent structures.

They are relatively one of the rarest pathologies.

In this analysis, authors aim to review the surgically treated cases of primary spinal cord tumors, to clarify the relative frequencies of these tumors, treated in our setup over a period of 15-years at King Hussein Medical Center.

Special emphasis devoted to analyze the clinical manifestations, radiological findings, histological subtypes, anatomical location, and the mid-term outcome following surgery of these lesions.

Methods : This study was conducted by reviewing retrospectively the: patient's admission records, neuroimaging, operation records, outpatient files, histopathology reports and clinical outcome documents which were compiled from all consecutive patients treated in single referral center, between January 2002 and January 2017.

Results : In a cohort of 414-patients with primary spinal cord tumors surgically treated during the period of this study.

The majority of the patients were male representing 58.21 % of patients.

The mean age at surgery was 53.6-years.Anatomically; there were 144-patients with intramedullary tumors, 181-patients (43.71 %), with intradural extramedullary tumors, 77-patients (18.59 %) with epidural tumors, and 12-patients (2.89 %) with dumbbell tumors.

The pathological diagnoses of the primary spinal cord tumors are classified based on the age of the patient, the anatomic location of the lesion, supplemented by modern imaging and tumor histology.

Conclusion : Primary spinal cord tumors are remarkably rare.

The recent surgical result of pain relief, neurological improvement, and local control rates suggest that surgery is effective in the treatment of patients with primary spinal tumors with minimal deterioration and complication rate.

The most reliable predicting factor of postoperative neurological outcome is the preoperative neurological state.
