Single-Photon Emission Computed Tomography, Computed Tomography Lymphoscintigraphy, and Intensity-Modulated Radiation Therapy in Treating Patients Who Have Undergone Surgery for Stage I or Stage II Breast Cancer
RATIONALE: Diagnostic procedures, such as single-photon emission computed tomography and computed tomography lymphoscintigraphy, may help lower the dose of radiation therapy after surgery, and help prevent lymphedema.
PURPOSE: This clinical trial is studying single-photon emission computed tomography and computed tomography lymphoscintigraphy followed by intensity-modulated radiation therapy to see how well they work in treating patients who have undergone surgery for stage I or stage II breast cancer.
Other: screening questionnaire administration
Procedure: computed tomography
Procedure: single photon emission computed tomography
Radiation: intensity-modulated radiation therapy
Radiation: technetium Tc 99m sulfur colloid

- To assess the feasibility of integrating Philips Precedence SPECT/CT® images with GE PET/CT Fusion software to reduce radiation dosimetry delivered to lymph nodes draining the arm in patients after surgery for stage I or II breast cancer.
- To examine the differences in radiation dosimetry in these patients using 3-D conformal radiotherapy with vs without the Philips Precedence SPECT/CT®.
- To compare reduction in lymph node radiation dosimetry in these patients using single photon emission computed tomography (SPECT) and computed tomography (CT) with 3-D conformal radiotherapy vs intensity-modulated radiotherapy.
OUTLINE: Patients receive filtered technetium Tc 99m sulfur colloid (TcSC) intradermally and undergo single photon emission computed tomography (SPECT) and computed tomography (CT) imaging at the time of TcSC and 2 hours after injection. Patients then undergo intensity-modulated radiotherapy of the whole breast, including the low axilla and lymph nodes identified by the Phillips Precedence SPECT/CT® at a dose determined by computer analysis of the imaging information.
Patients complete a lymphedema screening questionnaire at baseline and at 12 and 24 months after treatment.
