Objectives: The locally advanced breast cancer (LABC) covers large tumor heterogeneity. It consists of non-inflammatory LABC and inflammatory breast cancer (IBC). This study aimed to compare the epidemiological, clinical and pathological, as well as the prognosis of IBC versus non-inflammatory LABC.
Methods: This is a retrospective study of 150 cases of IBC and non-inflammatory LABC collected in medical oncology department of the CHU Hassan II of Fez during a period of 4 years [January 2009-January 2013]. Overall survival (OS) and disease-free survival (DFS) were calculated using the Kaplan-Meier method. Analysis of the various prognostic factors was performed according to the Cox model.
Results: IBC represented 28.7% of LABC. The median age was 47 years. The median tumor size was greater in non-inflammatory LABC compared with IBC (9.5 versus 6cm; P=0.0014). Lymph node invasion was more common in the IBC (49.7% versus 45.9%; P=0.01). An SBR grade 3 was more frequently noted in the IBC (P=0.011). The two groups were well balanced with regard to HR, HER2 status and pathologic complete response. Non-inflammatory LABC had the best OS and DFS (24 vs. 22 months; P=0.03 and 18 vs. 17 months; P=0.025 respectively).
Conclusion: IBC has a worse prognosis compared to non-inflammatory LABC. New therapeutic approaches are needed to improve the prognosis of these patients.

Background: Preoperative radiotherapy and chemoradiotherapy (PRT/PCRT) represent an increasingly used clinical strategy in different tumor sites. We have previously reported on a PRT/PRCT protocol in patients with locally advanced non-inflammatory breast cancer (LABC) with promising clinical results. However, concerns regarding a possible unfavorable influence on cosmesis still exist.

Background: Radiation therapy is an indispensable part of various treatment modalities for breast cancer. Specifically, for non-inflammatory locally advanced breast cancer (LABC) patients, preoperative radiotherapy (pRT) is currently indicated as a second line therapy in the event of lack of response to neoadjuvant chemotherapy. Still approximately one third of patients fails to respond favourably to pRT.

Aim: Inflammatory breast cancer (IBC) is the most aggressive form of locally advanced breast cancer. The signs of inflammation such as hyperemia and hyperthermia might suggest the possible participation of inflammatory mediators. This study investigates stromal and tumor expression of nuclear factor-kappa B (NF-κB) and interleukin-18 (IL-18) in samples obtained from IBC and noninflammatory locally advanced breast cancer (LABC) and the influence of these markers on patients' prognosis.

Purpose: The purpose of this analysis was to assess the tumor response and long-term outcome in patients treated with preoperative radiotherapy (PRT) without systemic therapy.
Methods: Between 1997 and 2000, 134 patients with non-inflammatory locally advanced breast cancer (LABC) were treated with PRT. The tumor dose was 45 Gy in 15 fractions to the breast and to regional lymph nodes over 6 weeks.
