Brief Summary
This phase II trial studies how well lapatinib ditosylate and radiation therapy work in treating patients with locally advanced or locally recurrent breast cancer. Lapatinib ditosylate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Radiation therapy uses high energy x rays to kill tumor cells. Giving lapatinib ditosylate together with radiation therapy may be an effective treatment for breast cancer.

Outcome Measures
Primary Outcomes (1)
Percentage of Patients Achieving Complete Clinical Response
Complete clinical response will be defined as the absence of tumor on the chest wall, in the treated breast, or in the nodal regions as assessed by clinical examination +/- radiographic imaging (if clinically indicated).
Up to 12 weeks
Secondary Outcomes (4)
Feasibility of Assessing the Effects of Lapatinib and Radiation Therapy on BCSCs Using Flow Cytometry and SCGEP
12 weeks
Change in the Proportion of BCSCs
Baseline to 12 weeks
Incidence of Adverse Events Graded According to Common Terminology Criteria for Adverse Events (CTCAE) Version 4.0
Up to 12 weeks
Pathologic Complete Response Rate for Those Patients Undergoing Surgical Resection Defined as no Evidence of Residual Tumor in the Breast and Lymph Nodes
Up to 12 weeks
Study Arms (1)
Lapatinib Plus Radiation Therapy
EXPERIMENTALPatients receive lapatinib ditosylate PO QD on day 1 until completion of radiation therapy. Beginning on day 7, patients undergo radiation therapy for 5-7 weeks and will have their blood banked for laboratory biomarker analysis.
Interventions
Given PO
Undergo radiation therapy
Eligibility Criteria
You may qualify if:
- Patients with histologically or cytologically confirmed locally advanced breast cancer that is refractory to chemotherapy or other therapeutic agents or with a history of breast cancer with new evidence of a local recurrence (defined as a chest wall or breast recurrence and/or nodal recurrence); the diagnosis will be made based on clinical and pathologic features
- Patients must be \>18 years of age.
- Karnofsky Performance Status (KPS) score \> 70
- Patts must have normal organ function as defined below:
- total bilirubin \< 1.5 x institutional upper limit of normal
- AST(SGOT)/ALT(SGPT) \< 2.5 x institutional upper limit of normal
- creatinine \< 1.5 x institutional upper limit of normal
- Patients must have left-ventricular ejection fraction \> 50% at baseline.
You may not qualify if:
- Patients who have contraindications to radiotherapy, such as scleroderma, dermatomyositis, or severe cutaneous manifestations of systemic lupus erythematosus (SLE)
- History of allergic reactions attributed to compounds of similar chemical or biologic composition to lapatinib
- Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, or psychiatric illness/social situations that would limit compliance with study requirements
- Women who are pregnant or lactating, as well as women of child-bearing potential who are unwilling or unable to use an acceptable method of birth control to avoid pregnancy for the duration of the study
