Abstract

Background Inflammatory breast cancer (IBC) is an uncommon clinicopathologic entity characterized by rapid progression and aggressive behavior. We used the National Comprehensive Cancer Network (NCCN) Outcomes Database to characterize recurrence patterns and outcomes.

Methods Patients with newly diagnosed IBC treated between 1999 and 2009 at 12 NCCN institutions were identified, and baseline characteristics were obtained. Patients had multimodality therapy if they received 2 of 3 treatments: surgery, perioperative (neoadjuvant or adjuvant) chemotherapy, or perioperative radiation. The first site of recurrence/metastatic diagnosis was identified. Overall survival was calculated on the basis of stage at diagnosis and receipt of multimodality therapy.

Results We identified 673 patients, of whom 195 (29%) had metastatic disease at presentation. Median follow-up was 29 months. Of patients in stage III, 82% received > 1 treatment modality. Among 203 patients in stage III with recurrence, the most frequent sites of first recurrence were bone (28%), central nervous system (CNS), lung, and liver (all 21%). Human epidermal growth factor receptor 2 positive and triple negative subtypes had higher rates of CNS recurrence (P =.001). Median survival was 66 months (95% confidence interval [CI], 54-107) for stage III and 26 months (95% CI, 22-33) for stage IV. Among 82% of patients in stage III receiving multimodality therapy, the median survival was 107 months (95% CI, 71 to not reached).

Conclusions This large, retrospective, multi-institutional study confirms the aggressive clinical features, unique recurrence patterns, and adverse prognosis of IBC. The high rate of CNS recurrence among high-risk subtypes, despite the inflammatory nature of the breast cancer, suggests that new strategies are needed for earlier detection or prevention of brain metastases to improve long-term prognosis.
