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

Description
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

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.
|
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.
