Brief Summary:
The purpose of this study is to determine if the planning of radiation treatment of prostate cancer patient can be made more precise by comparing currently planning techniques to an imaging technique called SPECT.

Condition or disease Intervention/treatment Phase
Adenocarcinoma of the Prostate Other: Single Photon Emission Computed Tomography (SPECT) Not Applicable

Detailed Description:

Single photon emission computed tomography (SPECT) uses radioactive tracers and a scanner to record data that a computer constructs into two- or three-dimensional images. A small amount of a radioactive drug is injected into the body and a scanner is used to make detailed images of areas inside the body where the radioactive material is taken up by the cells. Using a gamma camera (a special kind of scanner), we can create a better picture of the lymph node region. We will compare these pictures to images from your CT scan, to help plan your therapy.

The research in this study involves seeing if it is feasible to use SPECT scanning procedures for the purpose of planning your radiation treatment. We hope that doing so will allow us to more accurately and precisely plan radiation treatment to potential sites of cancer, and avoid delivering too much radiation to normal

Arm Intervention/treatment
Experimental: SPECT lymph node mapping
  1. Diagnostic pelvic CT
  2. Nuclear tracer injection (Tc-99m) - same time as the ACCULOC seed implantation
  3. CT simulation (2 hours after prostate markers are placed)
  4. SPECT lymphoscintigraphy (first set of images 3-6 hours after injection and second set may be obtained 18-24 hours after injection)
Other: Single Photon Emission Computed Tomography (SPECT)

Primary Outcome Measures :
  1. Determine the feasibility of using SPECT-LM [ Time Frame: Completion of enrollment of all patients ]

    Safety: The study will be feasible if no more than 80% of patients experience the following complications: infection requiring hospitalization or IV antibiotics, urinary retention requiring placement of a Foley catheter, moderate or severe allergic reaction to Tc99.

    Efficacy: The study will be feasible if at least 80% of patients have at least one identifiable lymph node on SPECT-LM.

Secondary Outcome Measures :
  1. Evaluate the extent to which current target delineation guidelines include actual lymphatic channels visualized on SPECT-LM in the study population. [ Time Frame: Completion of enrollment of all patients ]
    1. Greatest radial distance of lymphatic channel volume from vessel wall contour
    2. Fraction of lymphatic channel volume, normal tissue volume, and critical structure volumes included in radial expansions from vessel wall
