En Bloc Resection Versus Separation Surgery Combined With Radiotherapy for the Treatment of Spinal Oligometastatic Tumor.

November 9, 2023 updated by: Jianru Xiao, Shanghai Changzheng Hospital

En Bloc Resection Versus Separation Surgery Combined With Radiotherapy for the Treatment of Spinal Oligometastatic Tumor-A Multi-center, Prospective, Randomized, Controlled Study.

The purpose of this clinical trial is to explore the impact of En bloc surgery and separation surgery combined with radiation therapy on the prognosis and survival of patients with spinal oligometastatic cancer, describe the clinical results, and optimize future treatment goals

Study Overview

Detailed Description

Patients with oligometastatic diseases have been shown to have better prognosis than those with multiple metastatic diseases, and some patients have achieved long-term survival, thus being considered to benefit from more aggressive treatment. Active local treatment, including surgery and/or targeted radiotherapy, such as Stereotactic Radiosurgery (SRS) and Stereotactic body radiotherapy (SBRT), can be performed before or after systemic treatment. For both primary and oligometastatic tumors, radical treatment should be considered in order to achieve better survival and prognosis. The current research has explored the different effects of oligometastatic disease status on the prognosis of various cancers. However, there is currently no clear clinical or experimental confirmation of the impact on the survival and treatment outcomes of patients with oligometastatic spinal cancer. The purpose of this clinical trial is to explore the impact of En bloc hand surgery and separation surgery combined with radiotherapy on the prognosis and survival of patients with oligometastatic spinal cancer, Describe clinical outcomes and optimize future treatment goals

Study Population

According to the literature results, the median survival period of the experimental group was 20 months, while the median survival period of the control group was 11 months. The total study duration (enrollment+follow-up) was 48 months, and the enrollment time (assuming uniform enrollment speed) was 24 months. The bilateral alpha was 0.05, the beta was 0.2, and the ratio of sample size between the two groups was 2 (experimental group: control group). Through the difference test of median survival time, the experimental sample size was calculated: 110 cases in the experimental group, 55 cases in the control group, a total of 165 cases, Considering 10% detachment, a total of 182 samples are required.

Description

Inclusion Criteria:

  • 1) Be able to sign written informed consent.
  • 2) Age range from 18 to 75 years old, regardless of gender.
  • 3) Within conservative treatment, the patient still has uncontrollable pain, metastatic cancer lesions that still progress, spinal instability/potential instability, or symptoms of spinal cord/nerve compression.
  • 4) After the patient underwent Positron Emission Tomography-Computed Tomography (PET-CT) examination, it was indicated that there were no more than 3 metastatic organs and no more than 5 metastatic lesions in the whole body of cancer. Among them, there was at least 1 spinal metastasis and at most 5 spinal metastases.
  • 5) Imaging examinations (enhanced MRI, enhanced CT, X-ray) indicate the presence of spinal metastasis.
  • 6) The expected survival period is ≥ 6 months.
  • 7)No other surgical contraindications

Exclusion Criteria:

  • 1) Primary tumors of the spine or multiple tumors of the body, with>3 metastatic organs and>5 metastatic sites.
  • 2) Previously underwent spinal surgery, or received radiotherapy for the responsible segment of this treatment.
  • 3) Severe heart, lung, liver, kidney or other diseases affecting the surgery.
  • 4) Having cognitive impairment, sensory aphasia, and inability to understand basic instructions.
  • 5) Participated in clinical trials of other drugs or medical devices within 3 months prior to enrollment.
  • 6) Infectious diseases.
  • 7) Refuse to follow up or participate.
  • 8) The researchers determine that the patients are not suitable for enrollment this clinical trail.

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
Total en bloc spondylectomy for spinal oligometastases
Based on the medical history, physical signs, and imaging examination results, a definitely diagnosis of spinal oligometastasis tumor was made and perform a Total en bloc spondylectomy.
Total enbloc resection (TES) is one of the most challenging surgeries in spinal surgery and a classic surgical method. It not only relieve spinal cord compression and delays tumor recurrence, but also prolongs patient survival, significantly reduces hand surgery trauma, and improves surgical safety. However, for cases with extensive tumor invasion, methods such as separation surgery should be used to relieve spinal cord nerve compression, rebuild spinal stability, and provide conditions for postoperative radiotherapy.
Separation surgery combined with radiotherapy for spinal oligometastases
Based on the medical history, physical signs, and imaging examination results, a definitely diagnosis of spinal oligometastasis tumor was made and perform a Separation surgery. After surgical recovery, take a radiotherapy.
