Post Mastectomy Radiation w/ Breast Reconstruction (A221505)

RT CHARM: Phase III Randomized Trial of Hypofractionated Post Mastectomy Radiation With Breast Reconstruction

Objective

Overview

This randomized phase III trial studies how well hypofractionated radiation therapy works in preventing recurrence in patients with stage IIa-IIIa cancer who have undergone mastectomy. Hypofractionated radiation therapy delivers higher doses of radiation therapy over a shorter period of time and may kill more tumor cells that remain after surgery and have fewer side effects.

Key Inclusion Criteria

Inclusion Criteria:

  • Histologically confirmed invasive carcinoma of the breast of any of the following histologies (ductal, lobular, mammary, medullary, or tubular); in-situ disease alone is not allowed
  • Patients will be staged according to the TNM staging system; pathologic stage T0N1-2a, T1N1a-2a, T2N1-2a, T3N0-2a, all M0 status; pathological stage for all patients not receiving neoadjuvant chemotherapy; higher of the clinical or pathological T and N stage, if receiving neoadjuvant chemotherapy; patients with pathological N0 at the time of mastectomy are only eligible if biopsy-proven clinically N1 or N2 disease is documented prior to induction chemotherapy

    * Note: All patients with clinical, radiographic or pathological T4, N3 or involved internal mammary disease (N1b, N1c, and N2b) will not be eligible to enroll

  • No prior radiation therapy to the chest, neck or axilla
  • No prior history of ipsilateral breast cancer (invasive disease or ductal breast carcinoma in situ [DCIS]); lobular carcinoma in situ (LCIS) and benign breast disease is allowed
  • No history of prior or concurrent contralateral invasive breast cancer; benign breast disease, LCIS or DCIS of contralateral breast is allowed
  • No active collagen vascular diseases, such as: systemic lupus erythematous, scleroderma, or dermatomyositis
  • Negative inked histologic margins from mastectomy pathology (no invasive cells at margin)
  • No significant post mastectomy complications in the ipsilateral breast requiring an unplanned re-operation or admission for intravenous (IV) antibiotics; re-operation for margins evaluation, nodal completion and routine reconstruction is acceptable
  • Radiation oncologist intends to treat all target volumes and respect all normal tissues in accordance with the dosimetric constraints described (simulation before registration recommended)
  • Radiation oncologist is planning to treat regional lymph nodes including internal mammary nodes and meet acceptable protocol dosimetric requirements
  • Radiation oncologist is NOT planning to utilize a chest wall/scar boost
  • Patient must have undergone immediate reconstruction at the time of mastectomy or be planning to undergo reconstruction within 18 months after radiation
  • If a tissue expander is utilized it needs to be a fluid filled expander, NO air expander (unless completely deflated) during radiation therapy
  • For patients with diabetes, hemoglobin A1C test must have been performed =< 90 days prior to registration
  • No co-existing medical conditions with life expectancy < 5 years
  • No other malignancy within 5 years of registration with the exception of basal cell or squamous cell carcinoma of the skin treated with local resection only or carcinoma in situ of the cervix
  • Negative serum or urine beta-human chorionic gonadotropin (HCG) in women of child-bearing potential =< 7 days prior to registration; a female of childbearing potential is a sexually mature female who has not undergone a hysterectomy or bilateral oophorectomy and has not been naturally postmenopausal for at least 12 consecutive months
  • Women of child-bearing potential must agree to utilize a form of birth control or agree to undergo sexual abstinence during radiation therapy
  • Eastern Cooperative Oncology Group (ECOG) (Zubrod) performance status 0-1
