Evaluating the Adequacy of Giro-Couch to Support Prone Breast Boost Irradiation Using IMRT Technique With IGRT. (IN902)

August 2, 2011 updated by: Azimuth Therapy Ltd.

Evaluating the Adequacy of Giro-Couch to Support Prone Breast Boost Irradiation Using Intensity Modulated Radiation Therapy(IMRT)Technique With Image-guided Radiation Therapy(IGRT).

The purpose of this study is to evaluate the Giro-couch, an innovative patient support device for the application of prone RT for treatment of breast cancer. This study will assess the feasibility of a new positioning approach to facilitate the delivery of external beam, delivered to the lumpectomy cavity, (the boost dose, partial breast therapy).

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Unknown

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Treatments are applied with the subject in the supine position, in ~50 Gy per treatment (~2GY per fraction), over a period of five to six weeks. Energy in use is usually 6-15MV photons. Following the whole breast irradiation, a boost dose is given to the lumpectomy cavity, in order to further reduce the local recurrences in the immediate vicinity of the treated breast. The boost dose is usually applied with electrons, 6-18MEV. Sixteen Gy is the usual dose, 2 Gy/Fx, for 8 fractions.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

40 years and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

Description

Inclusion Criteria:

Women who satisfy all of the following conditions are the only patients who will be eligible for this study:

  • The patient must consent to be in the study and must have signed an approved consent form conforming to federal and institutional guidelines.
  • Patients must be ≥ 40 years old.
  • The patient must have stage I or II breast cancer. If stage II, the tumor size must be 3 cm or less.
  • Surgical treatment of the breast must have been lumpectomy. The margins of the resected specimen must be at least 2mm. Re-excision of surgical margins is permitted.
  • Gross disease must be unifocal.
  • The target lumpectomy cavity must be clearly delineated and the target lumpectomy cavity/whole breast reference volume must be ≤ 30% based on the treatment planning CT scan.
  • The lumpectomy cavity must be delineated with surgical clips by the surgeon.
  • Patients are eligible if, based on the postoperative/ simulation CT scan, prone boost RT is judged to be technically deliverable by a prone breast IMRT-IGRT technique.
  • Patients with a history of non-breast malignancies are eligible if they have been disease-free for 5 or more years prior to randomization and are deemed by their physician to be at low risk for recurrence. Patients with the following cancers are eligible if diagnosed and treated within the past 5 years: carcinoma in situ of the cervix, carcinoma in situ of the colon, melanoma in situ, and basal cell and squamous cell carcinoma of the skin.

Exclusion Criteria:

  • Men are not eligible for this study. Women with one or more of the following conditions also are ineligible for this study.
  • T0, T2 (> 3.0 cm), T3, stage III, or stage IV breast cancer (see Appendix A for TNM nomenclature and staging).
  • Suspicious microcalcifications, densities, or palpable abnormalities (in the ipsilateral or contralateral breast) unless biopsied and found to be benign.
  • Non-epithelial breast malignancies such as sarcoma or lymphoma.
  • Proven multicentric carcinoma (invasive cancer or DCIS) in more than one quadrant or separated by 4 or more centimeters.
  • Paget's disease of the nipple.
  • Synchronous bilateral invasive or non-invasive breast cancer.
  • Surgical margins that cannot be microscopically assessed or are positive at pathologic evaluation. (If surgical margins are rendered free of disease by re-excision, the patient is eligible.)
  • Clear delineation of the extent of the target lumpectomy cavity not possible.
  • Breast implants.
  • Prior breast or thoracic RT for any condition
  • Collagen vascular disease, specifically dermatomyositis, systemic lupus erythematosis, or scleroderma.
  • Pregnancy or lactation at the time of proposed randomization. Women of reproductive potential must agree to use an effective non-hormonal method of contraception during therapy.
  • Psychiatric or addictive disorders or other conditions that, in the opinion of the investigator, would preclude the patient from meeting the study requirements.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Ease of use and Comfort scale 1-5
Time Frame: Treatment Day 1 and Treatment Day 8
The endpoints will be assessed at the conclusion of the subject's first treatment on Treatment Day 1, and at the conclusion of the subject's treatment on Treatment Day 8. Thus the time frame for the Primary Outcome Measure for each subject is 1-8 days.
Treatment Day 1 and Treatment Day 8

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
