Inflammatory breast cancer (IBC) has an unfavourable prognosis despite the advances made in the treatment of breast cancer. Our study aimed to define immunohistochemistry-based surrogate subtype distribution to determine whether the breast cancer subtype accompanied survival outcome differences in IBC. Medical records of female breast cancer patients with non-metastatic inflammatory breast cancer admitted to our clinic between March 2000 and December 2015 were retrospectively reviewed. Patient demographics, clinical and pathological feature of the primary tumour, adjuvant treatment options and survival data were analysed. Intrinsic breast cancer subtypes were defined according to ER, PR, HER-2 and ki-67 status. We identified 129 non-metastatic inflammatory breast cancer patients. Median follow-up was 73 months. 10 (7.7%) were luminal A-like, 67 (51.9%) were luminal B-like, 37 (28.6%) were HER-2 positive, and 15 (11.6%) were triple negative (TNBC) by immunohistochemistry. There were no statistically significant differences between subtypes in terms of histological type, grade, tumour size and lymph node status. Median disease-free survival was 47 months (95% confidence interval [CI] 29.2-82.6) and median overall survival was 75 months (95% CI 64.7-90.8). Triple negative breast cancer showed poorer outcome than other subgroups. Presence of TNBC disease was associated with poorer outcome compared to luminal A (HR: 0.19, 95% CI 0.04-0.92, p: 0.039), luminal B (HR: 0.34, 95% CI 0.15-0.74, p: 0.007) and HER-2 positive subgroups (HR: 0.40, 95% CI 0.17-0.94, p:0.037). Luminal A patients had a trend to have a better overall survival which did not reach to a statistical significant difference. Our study put forth that IBC have a poor prognosis irrespective of breast cancer surrogate subtype distribution. Luminal A, the most frequent subtype of breast cancer was the least common in our IBC patient group. TNBC had the worst outcome when compared to other breast cancer subtypes.

The present study aimed to analyze the efficacy of maintenance therapy with single agent capecitabine for human epidermal growth factor receptor (HER2) negative metastatic breast cancer (MBC) patients following disease control with 6 cycles of docetaxel plus capecitabine chemotherapy as the first‑line treatment. As an initial treatment, 6 cycles of docetaxel plus capecitabine followed by maintenance therapy with capecitabine were administered. A total of 55 patients received combination therapy and 48 patients proceeded to maintenance therapy: Of these, 32 patients (66.7%) were postmenopausal and 37 (77.1%) had estrogen and progesterone receptor positive disease. The median progression‑free survival rate with maintenance therapy was 5.5 months (95% CI, 0‑11.4 months) and the median overall survival (OS) was 26.6 months (95% CI, 21.8‑30.1 months). The use of maintenance therapy improved previous responses in 4 patients (8.3%; 2 partial and 2 complete responses) and 32 patients (66.7%) had stable disease. The median number of maintenance therapy cycles applied was 6.5 (range 1‑28, total 441). The observation of side effects, including grade 3/4 neutropenia, febrile neutropenia and fatigue was more common during combination therapy. The results of the present study indicate that maintenance with single agent capecitabine therapy is an effective and tolerable treatment option for HER2 negative MBC patients in which disease control with 6 cycles of docetaxel plus capecitabine chemotherapy is achieved in the first-line setting.

Background: The primary objective of our study was to examine the clinical outcomes and prognosis of patients with metastatic renal cell carcinoma (mRCC) with brain metastases (BMs) receiving targeted therapy. Patients and methods: Fifty-eight patients from 16 oncology centers for whom complete clinical data were available were retrospectively reviewed. Results: The median age was 57 years (range 30-80). Most patients underwent a nephrectomy (n = 41; 70.7%), were male (n = 42; 72.4%) and had clear-cell (CC) RCC (n = 51; 87.9%). Patients were treated with first-line suni-tinib (n = 45; 77.6%) or pazopanib (n = 13; 22.4%). The median time from the initial RCC diagnosis to the diagnosis of BMs was 9 months. The median time from the first occurrence of metastasis to the development of BMs was 7 months. The median overall survival (OS) of mRCC patients with BMs was 13 months. Time from the initial diagnosis of systemic metastasis to the development of BMs (<12 months; p = 0.001), histological subtype (non-CC; p2; p<0.05) were significantly associated with OS in multivariate analysis. There were no cases of toxic death. One mRCC patient with BMs (1.7%) experienced treatment-related cerebral necrosis. All other toxicities included those commonly observed with VEGF-TKI therapy. Conclusions: The time from the initial diagnosis of systemic metastasis to the development of BMs (2) were independent risk factors for a poor prognosis.
