Cosmetic Result/Toxicity in Post-Mastectomy Immediate Reconstruction Expander+RT
This trial is active, not recruiting.
|Sponsor||Dana-Farber Cancer Institute|
|Collaborator||Brigham and Women's Hospital|
|Start date||October 2009|
|End date||December 2016|
|Trial size||32 participants|
|Trial identifier||NCT01664091, 09-254|
This research study is being done to carefully evaluate the effect of giving radiation therapy after temporary breast reconstruction. The investigators want to see if this type of reconstruction combined with radiation will look better (once the final reconstruction has been completed) and will reduce the risk that the participant will develop complications that sometimes occur with other kinds of reconstruction procedures. The investigators also want to know if it is easier to give the radiation with this type of reconstruction than with other kinds of reconstruction procedures. The reconstruction procedure involves the temporary use of a tissue expander and an acellular dermal matrix (ADM).
The success rate of immediate reconstruction with a tissue expander and acellular dermal matrix followed by radiation therapy.
time frame: 2 years
To evaluate the volumes of lung and heart (if left-sided) included in the radiation fields.
time frame: 2 years
To assess the extent and location of contracture.
time frame: 2 years
Male or female participants at least 18 years old.
- Patients must have newly diagnosed, clinical Stage I-III breast cancer with T1-T3 invasive tumors recently treated with mastectomy
- Patients must have had immediate reconstruction with a TE and ADM
- Participants must be candidates for postmastectomy radiation therapy (RT). Postmastectomy RT routinely is indicated for patients with pathologically-staged T3N1 (or higher stage) tumors, T1-T2 tumors with 4 or more positive nodes, some T1-T2 tumors with 1-3 positive nodes, and, infrequently, for some N0 tumors
- Axillary nodes may be positive or negative
- Microscopically positive margins are permitted
- Systemic therapy as recommended by a medical oncologist, pre-or post-mastectomy, is permitted
- Patients must agree to return for scheduled follow-up visits with their radiation oncologist 6, 12, 18 and 24 months after RT (+/- 1 month)
- 18 years of age or older
- Participants with T4 tumors
- Participants with recurrent breast cancer or a history of prior breast RT
- Uncontrolled intercurrent illness including, but not limited to ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
- Pregnant women are excluded from this study
- Individuals with a history of a different malignancy are ineligible except for the following circumstances. Individuals with a history of other malignancies are eligible if they have been disease-free for at least 5 years and are deemed by the investigator to be at low risk for recurrence of that malignancy. Individuals with the following cancers are eligible if diagnosed and treated within the past 5 years: cervical cancer in situ, and basal cell or squamous cell carcinoma of the skin
- HIV-positive individuals on combination antiretroviral therapy
|Official title||An Evaluation of Cosmetic Results and Toxicity in the Use of Post-Mastectomy Immediate Reconstruction With a Tissue Expander and Acellular Dermal Matrix Followed by Radiation Therapy|
|Principal investigator||Julia Wong, MD|
|Description||- ADMs have been used in combination with a tissue expander and radiotherapy but have not been studied formally in terms of their ability to avoid complications sometimes seen with other methods of reconstruction and improve the delivery of the radiation. The only difference between being on the study and not being on the study is that the research team will analyze the records of those who participate to see how easy it was to give the radiation, how good the cosmetic outcome of the reconstruction is and what, if any, complications occured. - A minimum of 6 weeks between the surgery and the start of radiation therapy is required to allow for adequate healing. Often this interval will be longer, as many patients will receive chemotherapy in the interim. There is no maximum time from surgery to radiation. - Around the time of radiation planning, the radiation oncologist and plastic surgeon will agree upon how much deflation of the tissue expander will be required to permit simulation of the radiation therapy. - Radiation therapy to the chest wall (with or without adjacent lymph nodes) will be given once daily Monday through Friday over 5-7 weeks. - After the completion of the radiation therapy, the tissue expander will be re-expanded and eventually replaced by the permanent implant or flap reconstruction at the discretion of the plastic surgeon. - Participants will be expected to return to the Radiation Oncology Clinic for follow-up visits 6, 12, 18 and 24 months after the end of the radiation therapy. Evaluation of cosmetic results and complications will be done at these visits using a recognized scoring system and photographs taken at each time point and scored for specific items (necrosis, telangiectasia, etc).|
