Experimental: treatment of metastatic liver disease
The intervention is the use of image guidance with general anesthesia and suspended ventilation during treatment delivery. This will allow precise localization and delivery of dose to the tumor.
Procedure: image guidance with general anesthesia and suspended ventilation during treatment delivery
All study patients will undergo marker implantation approximately 2 weeks prior to the PET-CT simulation and treatment planning. PET-CT is performed for treatment planning purposes. This part of the process is in routine clinical use at MSKCC.
Three cone beam imaging scans and an IV contrast injection just prior to the first cone beam scan will be added to the standard procedure. The use of these two techniques is investigational.
The treatment delivery will make use of general anesthesia and suspension of mechanical ventilation to render the patient apneic during both target localization and dose delivery. This will allow the dose to be delivered more precisely than the techniques currently in use, thus allowing the use of smaller treatment margins and reducing the high dose exposure of healthy liver tissue. These measures have not previously been used for treatment delivery.
- To assess safety & feasibility of single dose image-guided intensity modulated radio (IG-IMRT) using gen anesthesia with apneic oxygenation & controlled ventilation to temp suspend respiratory motion for tx of mets liver disease during localization & tx. [ Time Frame: conclusion of study ]
