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.

Primary Outcome Measures:
  • Philips Precedence SPECT/CT® and GE PET/CT Fusion software integration
  • Dosimetry differences between 3-D conformal radiotherapy with vs without the Philips Precedence SPECT/CT®
  • Lymph node dosimetry differences between single photon emission computed tomography (SPECT) and computed tomography (CT) with 3-D conformal radiotherapy vs intensity-modulated radiotherapy
  • Association between radiation exposure and limb volume, circumferential wrist measurements, circumferential forearm measurements, and extra-cellular fluid measurements

Estimated Enrollment: 30
Study Start Date: September 2008
Study Completion Date: October 2016
Primary Completion Date: October 2016 (Final data collection date for primary outcome measure)
Detailed Description:


  • 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.
