Study summary

Intra-spinal canal tumors are the general term of primary tumors from spinal cord or various tissues in the spinal canal and adjacent to the spinal cord, while the metastatic tumors are those from other sites other than spinal canal. Intra-spinal canal tumor is one of the most common diseases in neurosurgery, and surgery is the most effective treatment. Conventional open surgery is required to remove the posterior structures of the spine, which would lead to fracture of the posterior tension band, soft tissue injury, spine instability, and even spine deformity. So it is very important to protect and rebuild the posterior tension band for the stability of the spine. The team of Dr. John P. Kostuik from the Department of Orthopedics and Neurosurgery, the Johns Hopkins University, firstly introduced minimally invasive surgery for cervical and lumbar degenerative disease. However it has not been applied to the treatment of intra-spinal canal tumors. To date, the microsurgery of intra-spinal tumor through the trans-Quadrant channel pathway has not been widely performed in clinical practice. The investigators performed the microsurgery of intra-spinal canal tumor through the trans-Quadrant pathway in some patients previously and succeeded in the surgical treatments. The investigators analyzed the clinical data retrospectively, including surgical incision length, the volume of bleeding during operation, post-operative drainage volume, post-operative out-of-bed time point, post-operative length of stay in hospital, and post-operative visual analog pain (VAP) score. The group of patients using microsurgical technique through trans-Quadrant channel pathway showed better outcome compared with the group of patients using conventional open surgery. This innovation of microsurgery showed fewer traumas and bleeding, more rapid recovery, better prognosis and more safety in practice. Since there are some limitations to the retrospective study, it is necessary to design a prospective randomized controlled trial of the treatment of intra-spinal canal tumors using microsurgical technique through trans-Quadrant channel pathway.

Read the detailed description

This study is the prospective randomized controlled clinical trial.

  1. Patient Recruitment: Patients who meets the diagnostic criteria of intra-spinal canal tumor and has surgical indications from May 2016 to June 2018 in the department of neurosurgery of our hospital could be recruited.
  2. Screening: Demographic characteristics, such as gender, age, history of diseases (including but not limited in diabetes, heart disease, smoking history, and operation history, etc.), related laboratory tests (blood routing test, liver and kidney functions, electrolytes, blood coagulation function, and ECG, etc.) before entering either group.
  3. Grouping: Patients who meets the diagnostic criteria and does not meet the exclusion criteria would be assigned into the experimental group and control group randomly. The informed consent forms should be signed before grouping.
  4. Surgery: Patients in the experimental group will receive operation using microsurgical techniques through trans-Quadrant channel pathway. Patients in the control group will receive conventional open surgery.
  5. Post-operative Observation and Follow-up: Clinical data will be collected after surgery and during follow-up. The time points include the 1st day, 7th day, 30th day, 90th day, and 180th day after surgery.
  6. Statistical Analysis: Statisticians are blinded to the clinical data and grouping. The software SPSS (V. 16.0) will be used in statistics.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • The patient should meet the diagnostic criteria of intra-spinal canal tumors and the indications for surgery. Meanwhile, the length of tumor should no more than 5 cm, and the cross-sectional area should be less than 2/3 of the respective area of the spinal canal.
  • The patient was never be treated with any spinal surgery.
  • There was no cognitive impairment before onset of diseases or other diseases which can cause cognitive dysfunction.
  • The patient should sign the forms.

Exclusion criteria

Exclusion Criteria:

  • The patient is diagnozed as non intra-spinal canal tumors, spinal degenerative diseases, or other spinal diseases.
  • The patient received spinal surgery previously.
  • The patient suffered from serious heart, lung, liver, or kidney insufficiency.
  • The patient has other spinal and spinal cord diseases rather than intra-spinal canal tumor, such as disc herniation, vertebral fractures.
  • The patient has severe diabetes, coronary heart disease, coagulation disorders, difficult to correct before operation, or cannot tolerate surgery.
  • The patient has other surgical .
  • The patient is pregnant or breast-feeding.

Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Study arms

  • Experimental
    Trans-Quadrant Channel Surgery

    Patients in the experimental arm (experimental group, i.e. microsurgery through trans-Quadrant channel pathway) will be operated using Quadrant channel system. All the tumor resection will be operated through the Quadrant channel with assistance of microsurgical techniques.

    Procedure: Trans-Quadrant Channel Surgery

  • Active comparator
    Conventional Open Surgery

    Patients in the active comparator arm (control group, i.e. conventional open surgery) will be operated using the conventional open surgery. All the tumor resection will be operated directly with conventional procedures. More posterior structures of spine will be removed.

    Procedure: Conventional Open Surgery

Interventions

  • ProcedureTrans-Quadrant Channel Surgery

    Patients in the experimental group will be general anaesthetized and placed in the prone position. Intra-operational electrophysiological monitoring will be used. Kirschner wire will be used to identify the position of the Quadrant channel with X-ray. After disinfection and draping, an incision of 3cm long and 2-3cm lateral to midline on the tumor side will be made. Soft tissues will be separated. Graded dilators will be used to establish Quadrant channel. Kerrison clamps will be used to expose the very local posterior spinal structures. Vertebral plate will be windowed with power drill to expose dural mater, and tumors will be removed with microsurgical techniques. Hemostasis will be performed after resection. Dural mater will be closed by titanium clips, and close incision by layers.

  • ProcedureConventional Open Surgery

    Patients in the control group will be general anaesthetized during operation and placed in the prone position. Intra-operational electrophysiological monitoring will be used. Surgeons will locate the lesion by X-ray. After disinfection and draping, the midline incision of 7-10 cm and centered by the lesion segment will be made. Soft tissues will be cut and separated to expose posterior structure of spine. The root of spinal process and half of the vertebral plate on tumor side of certain segments will be removed. The dural mater will be opened. Then surgeons will remove tumor with microsurgical techniques. Hemostasis will be precisely performed after resection, and dural mater will be closed by suturing. Incision will be closed by layers. Drainage would be placed if necessary.
