4D Image-Guided Partial Breast Radiation in Stage 0 and l Breast Cancer
25. oktober 2018 oppdatert av: Yale University
A Pilot Study of Four-Dimensional Conformal Image Guided Accelerated Partial Breast Irradiation In The Treatment Of Stage 0 and l Breast Cancer
The Purpose of this study is to evaluate the feasibility of using image guidance and four-dimensional computed tomography to reduce the volume of non target breast tissue that is treated with accelerated partial breast irradiation via the external beam technique.

Detaljert beskrivelse
This is a pilot study enrolling about 30 patients to evaluate the feasibility of using 4D CT and daily image guidance in Accelerated Partial Breast Irradiation (APBI) to decrease set-up error and individualized planning target volumes to limit the non-target breast tissue dose.
The two specific breasts constraints which shall be decreased are the V50 (percent volume of breast receiving 50% of the prescribed dose) and the V100 (percent volume of breast receiving 100% of the prescribed dose).
The goal will be to decrease these to 45% and 23.5% respectively, which is down 33% from the NSABP B39 standard of 60% and 35%.

Beskrivelse
Inclusion Criteria:
- The patient must consent to be in the study and must have a signed an approved consent form conforming with institutional guidelines.
- Patient must be > 50 years old.
- The patient should have a life expectancy of at least two years with a karnofsky performance status > 70.
- The patient must have stage 0 or I breast cancer.
- On histological examination, the tumor must be DCIS or invasive adenocarcinoma of the breast.
- Surgical treatment of the breast must have been lumpectomy. The margins of the resected specimen must be histologically free of tumor (>2mm, DCIS and invasive). Re-excision of surgical margins is permitted.
- Gross disease must be unifocal with pathologic (invasive and/or DCIS) tumor size 2 cm or less. (Patients with microscopic multifocality are eligible as long as total pathologic tumor size is 2 cm or less.)
- Patients with invasive breast cancer are required to have axillary staging which can include sentinel node biopsy alone (if negative), sentinel node biopsy followed by axillary dissection or sampling with a minimum total of 6 axillary nodes or axillary dissection alone (with a minimum of 6 axillary nodes). Axillary staging is NOT required for patients with DCIS.
- The patient must have simulation within 8 weeks/56 days of the final surgery for their breast cancer (lumpectomy, re-excision of margins, or axillary staging procedure).
- Patients with a history of non-ipsilateral breast malignancies are eligible if they have been disease-free for 2 or more years prior to enrollment. Patients with the following cancers are eligible even if diagnosed and treated within the past 2 years: carcinoma in situ of the cervix, colon, melanoma in situ, and basal cell and squamous cell carcinoma of the skin.
- Chemotherapy is permitted if planned for ≥ 2 weeks after radiation.
- Urine pregnancy test must be performed and be negative on all women younger than 60 who have not had a tubal ligation, oophorectomy, or hysterectomy.
- Separate incisions for the lumpectomy and sentinel node biopsy should be present. Use of only one incision will typically result in a contiguous cavity with the tumor bed and the sentinel node sampling, and inability of the radiation oncologist to delineate the tumor bed from the sentinel node bed.
- The patient must have a cavity which is able to be targeted with external beam APBI, either through surgical clip placement, or CVS 3 or higher. The cavity to whole breast ratio must be 30% or less.
Exclusion Criteria:
- Men are not eligible for this study as men are not breast conservation candidates.
- T0, T2 (> 2.0 cm), T3, node positive, stage III or IV breast cancer.
- Any positive axillary nodes.
- Palpable or radiographically suspicious ipsilateral or contralateral axillary, supraclavicular, infraclavicular or internal mammary nodes, unless biopsy proven to be negative for tumor.
- Suspicious microcalcifications, densities or palpable abnormalities in either breast unless biopsy proven to be benign.
- Non-epithelial breast malignancies such as sarcoma or lymphoma.
- Proven multicentric carcinoma in more than one quadrant or separated by more than 2 centimeters.
- Paget's disease of the nipple.
- History of invasive breast cancer or DCIS in the same breast.
- Surgical margins that cannot be microscopically assessed or are less then 2 mm.
- Collagen vascular disease, specifically dermatomyositis with a CPK level above normal or with an active skin rash, systemic lupus erythematosis or scleroderma.
- Pregnancy or lactation at the time of proposed radiation. 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 treating physician, would preclude the patient from meeting the study requirements.
- Patients with coexisting medical conditions in whom life expectancy is < 2 years.
- Patients with skin involvement, regardless of tumor size.

Cosmesis by Patient Report
Tidsramme: Within no more than 8 weeks of surgery, but prior to the start of radiation
|
This outcome is measured by the Breast Cancer Treatment outcome Scale (BCTOS).
Eleven items (e.g., breast size, breast pain, breast shape) are rated by patients on a 4-point scale (0=no difference to 3=large difference), with a score range of 0-33 (higher scores signifying worse outcome).
Scores on each item are summed to obtain a total score.

Medical doctor will be provided with cosmesis scale and grade cosmesis of breast.
Cosmesis was based on the Harvard Cosmesis Scale rated as :1.
excellent: the treated breast looked essentially the same as the opposite breast; 2. good: minimal but identifiable effects of radiation on the treated breast; 3. fair: significant effects of radiation on the breast were noted; 4. severe normal tissue sequelae.
