Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: The study population consists of patients who have undergone treatment for ISCM at one of the participating hospitals in the period from 2017 to 2023. The study period is chosen, as electronic documentation is available at all hospitals in this time-period.

About this study

Official title: Microsurgical Resection of Intramedullary Spinal Cord Metastases - a Retrospective International Multicenter Study

The aim of the study is to establish a multi-center, retrospective database for patients with intramedullary spinal cord metastases (ISCM) and analyse the functional outcome in surgically treated ISCM patients.

The hypothesis is that the surgical treatment of selected ISCM patients does not lead to persistent morbidity and does not increase mortality, compared to patients that are treated non-operatively.

Secondary objectives are to assess pre- to postoperative neurological deficits, ambulatory status, and overall survival of surgically treated ISCM patients.

The investigators intend to include a control cohort of patients with ISCM from participating centers, who underwent non-surgical oncological treatment (radiotherapy with or without chemotherapy). This control cohort of patients will be used to match patients with and without surgical treatment.

Primary endpoint (analysed in surgically treated ISCM patients):

Functional outcome at 90 days after treatment initiation, measured by the modified McCormick Scale. This is a score for grading of neurological function in spinal cord conditions.

The McCormick scale ranges from Grade I (neurologically intact) to grade V (paraplegic or quadriplegic). The McCormick scale is suitable for our retrospective study because of its good reproducibility and comparability.

Secondary endpoints (analysed in surgically treated ISCM patients and analysed in matched patients with and without surgical treatment):

  • Functional outcome by the McCormick scale and the modified Japanese Orthopaedic Association scale (mJOA) at 6 and 12 months. This is a score evaluating motor function of upper and lower extremities, sensory function of upper extremities and sphincter function / voidance. The mJOA ranges from 0 - 18 points, with higher score values representing better functional outcome. The minimum clinically important difference of the mJOA is 1-2 points, and scores lower than 14 indicate moderate myelopathy, scores lower than 11 indicate severe myelopathy.
  • Ambulatory status and continence at 90 days, 6 \& 12 months (determined by mJOA subscores)
  • Neurological outcome, measured by American Spinal Cord Injury Association (ASIA)
  • Impairment Scale at 90 days, 6 and 12 months
  • Rate \& type of complications at 90 days after treatment according to The Novel Therapy
  • Disability-Neurology Grade (TDN grade)16
  • Overall survival (in days)

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Microsurgical resection of ISCMProcedure or surgery

    Microsurgical resection of ISCM defines the surgical removal of cancerous tumors that have spread to the spinal cord, using advanced microsurgical techniques and equipment like ultrasound, neuromonitoring, ultrasonic aspirator to prevent damage to the spinal cord.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Functional outcome at 90 days after treatment initiation

    measured by the modified McCormick Scale. This is a score for grading of neurological function in spinal cord conditions.

    The McCormick scale ranges from Grade I (neurologically intact) to grade V (paraplegic or quadriplegic). The McCormick scale is suitable for our retrospective study because of its good reproducibility and comparability.

    Measured: at 90 days after treatment initiation

Secondary outcomes (4)
  1. Functional outcome

    modified Japanese Orthopaedic Association Score (mJOA) Range 0-18, with lower scores indicate a more sever myelopathy

    Measured: at 3, 6 and 12 months after treatment initiation

  2. Neurological outcome

    measured by American Spinal Cord Injury Association (ASIA) Impairment Scale (AIS) A: Complete. No sensory or motor function is preserved in sacral segments S4-S5, no sacral sparing B: Sensory Incomplete. Sensory but not motor function is preserved below the neurological level and includes sacral segments S4-S5, AND No motor function is preserved more than three levels below the motor level on either side of the body C: Motor Incomplete. Motor function is preserved below the neurological level AND More than half of the key muscle functions below the neurological level of injury have a muscle grade of less than 3 (Grades 0-2) D: Motor Incomplete. Motor function is preserved below the neurological level AND At least half (half or more) of the key muscle functions below the neurological level of injury have a muscle grade ≥ 3 E: Normal. If sensation and motor function are graded as normal in all segments AND the patient had prior SCI-related deficits

    Measured: at 6 and 12 months after treatment initiation

  3. Rate & type of complications

    Therapy-Disability-Neurology Grade (TDN Grade) Range: Grade 1-5 The Therapy-Disability-Neurology (TDN) grading system is a novel multidimensional classification of complications severity.

    higher Grades indicate higher severity of complication

    Measured: within 90 days after treatment initiation

  4. Functional outcome

    measured by the modified McCormick Scale. This is a score for grading of neurological function in spinal cord conditions.

    The McCormick scale ranges from Grade I (neurologically intact) to grade V (paraplegic or quadriplegic). The McCormick scale is suitable for our retrospective study because of its good reproducibility and comparability.

    Measured: at 6 and 12 months after treatment initiation

Questions about this trial

What is this clinical trial studying?

An observational study of Spinal Cord Metastasis and Spinal Cord Tumor Malignant Intramedullary, run by Cantonal Hospital of St. Gallen at 1 site in Switzerland.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 21 Aug 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Switzerland. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Martin N. Stienen, PD, MD (+41 71 494 2183, martin.stienen@kssg.ch), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Functional outcome at 90 days after treatment initiation (time frame: at 90 days after treatment initiation). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 Aug 2024.
