Setup Variation in the Supraclavicular Lymph Nodes Treatment in Breast Cancer Patients

This study has been completed.

M.D. Anderson Cancer Center Identifier:
First received: April 8, 2008
Last updated: October 5, 2015
Last verified: October 2015
The goal of this clinical research study is to use the On Board Imager kilovoltage (OBI KV) system and cone beam computed tomography (CBCT) scanning or CT-on-rail system to look at how well a routine device called an electronic portal imaging device (EPID) can set up a patient to receive radiation therapy on the lymph nodes in the neck.

Condition Intervention
Breast Cancer
Procedure: CBCT Scan
Procedure: OBI KV Imaging

Study Type: Observational
Study Design: Observational Model: Case-Only
Time Perspective: Prospective
Official Title: A Pilot Study of Setup Variation in the Supraclavicular Lymph Nodes Treatment in Breast Cancer Patients Using On-Board Imaging System With Linear Accelerator

Further study details as provided by M.D. Anderson Cancer Center:

Primary Outcome Measures:
  • System Failure (defined as 2 or more disagreements between the EPID and either OBI systems or CT-on-rail from among the 5 evaluations for a particular patient) [ Time Frame: CBCT scanning and OBI R or CT-on-rial system, 5 evaluations per patient, during 5-week radiation treatment period ]

Enrollment: 28
Study Start Date: March 2008
Study Completion Date: October 2014
Primary Completion Date: October 2014 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
OBI KV System + CBCT Scanning
Breast cancer patient radiation treatment set up using OBI KV system and CBCT scanning or CT-on-rail system to verify standard EPID for positioning.
Procedure: CBCT Scan
Cone Beam Computed Tomography (CBCT) scan performed once a week.
Procedure: OBI KV Imaging
On Board Imager kilovoltage (OBI KV) Imaging performed once a week.

  Show Detailed Description


Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
Patients diagnosed with breast cancer.

Inclusion Criteria:

  1. Histologically confirmed carcinoma of the breast.
  2. American Joint Committee on Cancer (AJCC) Stage I-III, or locally recurrent breast cancer
  3. Planned for radiation treatment of the supraclavicular and axillary apex nodal beds using a SCV field
  4. Age greater than or equal to 18 years, since classic breast cancer is a disease of adults
  5. Able to understand the current trial and give informed consent

Exclusion Criteria:

  1. Has bilateral breast cancer requiring radiation to both breasts due to anatomic constraints on planning CT
  2. inflammatory carcinoma due to altered treatment schedule
