This phase II trial studies how well radiation therapy with or without olaparib works in
treating patients with inflammatory breast cancer. Radiation therapy uses high energy x-rays
to kill tumor cells and shrink tumors. Olaparib may stop the growth of tumor cells by
blocking some of the enzymes needed for cell growth. It is not yet known whether radiation
therapy with or without olaparib may work better in treating patients with inflammatory
I. To compare the invasive disease-free survival (IDFS) of patients with inflammatory breast
cancer receiving concurrent administration of olaparib with standard doses of radiotherapy to
the chest wall and regional lymph nodes compared to standard doses of radiotherapy alone to
the chest wall and regional lymph nodes.
I. To compare the effect of concurrent administration of olaparib with radiotherapy versus
radiotherapy alone on improvement in locoregional control (measured by locoregional
recurrence-free interval), distant relapse-free survival, and overall survival in
inflammatory breast cancer patients.
I. To collect tissue and whole blood for processing and banking in anticipation of future
correlative studies in this patient population.
OUTLINE: Patients are randomized to 1 of 2 groups.
GROUP I: Patients receive olaparib orally (PO) twice daily (BID) the day before standard
radiation therapy (RT) commences (Day 0) and throughout the RT course until the last day of
RT administration. Olaparib is also continued on weekends (routine days without RT)
throughout the RT course. Patients undergo radiation therapy 5 days per week for 6 weeks in
the absence of disease progression or unaccepted toxicity.
GROUP II: Patients undergo standard radiation therapy 5 days per week for 6 weeks in the
absence of disease progression or unaccepted toxicity.
After completion of study treatment, patients are followed up within 5 weeks, then every 3
months until 3 years after registration, and then every 6 months for up to 8 years after
