Image-Guided Navigation for High Dose Rate Temporary Interstitial Brachytherapy in the Palliative Management of Previously Treated Tumors of the Spine and Pelvis

This study is ongoing, but not recruiting participants.

The purpose of this study is to see if using a form of imaging during surgery helps the doctors to guide the placement of radiation catheters more accurately.

This method, called "image-guided surgical navigation" may allow the doctors to deliver radiation to the tumor that the patient needs and decrease the amount of radiation delivered to the nearby areas.

Condition Intervention
Metastatic or Recurrent Lesions in the Spine
Metastatic or Recurrent Lesions in the Pelvis
Radiation: Ir-192 high dose rate (HDR)

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Supportive Care
Official Title: A Pilot Study of Image-Guided Navigation for High Dose Rate Temporary Interstitial Brachytherapy in the Palliative Management of Previously Treated Tumors of the Spine and Pelvis

Further study details as provided by Memorial Sloan Kettering Cancer Center:

Primary Outcome Measures:
  • feasibility of High Dose Rate (HDR) treatment [ Time Frame: 1 year ]

    of spine and/or pelvis lesions using catheters placed under image guided navigational techniques, to provide improved dosimetric coverage of spinal lesions such that.

    In terms of technical feasibility, a patient is regarded as being successfully treated if the target D90 is ≥ 80% AND the cord/cauda max dose is 8 Gy.

Secondary Outcome Measures:
  • Toxicity of HDR brachytherapy [ Time Frame: 1 year ]
    for previously irradiated lesions of the spine and/or pelvis, defined as an acceptable level of severe toxicity (both acute and late effects) in the setting of HDR brachytherapy treatment. Severe toxicity will be defined as ≥ grade 3 NCI CTCAE v 4.0 toxicity that is at least possibly related to treatment

Estimated Enrollment: 20
Study Start Date: January 2013
Estimated Study Completion Date: December 2017
Estimated Primary Completion Date: December 2017 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Ir-192 high dose rate (HDR)
This pilot study is an investigation into the use of Ir-192 high dose rate (HDR) afterloader-based brachytherapy with catheter placement using image-guided surgical navigation techniques for patients with painful/symptomatic metastatic or recurrent lesions in the spine and/or pelvis that have been maximally treated with external beam radiation therapy.
Radiation: Ir-192 high dose rate (HDR)
Patients will be followed at 2 months (+/- 2 weeks) post-treatment and then approximately every 3 months (+/- 2 weeks) until approximately 11 months of follow up. They will be evaluated for pain referable to the treated site, clinical and radiographic evidence of local progression, and treatment related toxicity. Thereafter, patients will be followed as clinically indicated.


Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Patients must have histologic proof of a malignancy suitable for radiation therapy.
  • Patients must have received prior external beam radiation therapy to the region proposed for HDR brachytherapy treatment; evaluation of doses previously delivered to spinal cord/cauda equine, pelvis, and other critical structures (bowel, kidneys, rectum) will be taken into consideration.
  • If repeat irradiation would exceed any normal tissue constraint set by MSKCC Radiation Oncology Department dose constraint criteria, the patient will potentially be eligible.
  • If the total prior radiation dose to the cord or pelvis exceeds 100 Gy BED equivalent, the patient will be potentially eligible, where a total of 100 BED Gy equivalent is determined by the biological equivalent dose (BED) calculation; BED = nd(1 + d/α/β), where n = number of fractions and d = dose per fraction; α/β is the constant for spinal cord late effect and equals 2. [Rades 2005, Nieder 2005, Sahgal 2012]
  • KPS ≥ 60
  • Age ≥ 18 years old

Exclusion Criteria:

  • Patients who may receive therapeutically effective doses via an external beam approach to the lesion of interest as specified by MSKCC Radiation Oncology Department dose constraint criteria.
  • Patients with kyphoplasty cement or hardware that would preclude effective catheter placement.
  • Patients with paraspinal extension of disease with visceral involvement.
  • Abnormal complete blood count. Any of the following:
  • Platelet count < 75,000/ml
  • Hb level < 9gm/dl
  • WBC < 3.5/ml
  • Abnormal coagulation profile: INR > 2.5 and/or PTT > 80
  • Patients who are on anticoagulation medication that may not be safely held for the procedure (≥ 5 days for antiplatelet agents and warfarin; ≥ 24 hours for low-molecular weight heparin formulations) will be excluded.
  • Contraindications to general anesthesia
