Outcome of 561 non-metastatic triple negative breast cancer patients: Multi-center experience from Turkey
Purpose: Triple-negative breast cancers account for 15% of breast carcinomas and, when present as early-stage disease, they are associated with higher rates of recurrence and early distant metastasis risk when compared to hormone receptor positive and human epidermal growth factor receptor (HER-2) positive breast cancers. In this study we aimed to explore the basic clinicopathological characteristics, prognostic factors and recurrence patterns of non-metastatic triple negative breast cancer patients
Childhood, Adolescents, and Young Adults (<= 25 y) Colorectal Cancer: Study of Anatolian Society of Medical Oncology
Purpose: To evaluate the clinicopathologic characteristics and treatment outcomes of young patients with colorectal cancer (CRC)
Biological Subtypes and Distant Relapse Pattern in Breast Cancer Patients After Curative Surgery (Study of Anatolian Society of Medical Oncology)
PURPOSE: The aim of the study was to investigate the association between the molecular subtypes and patterns of relapse in breast cancer patients who had undergone curative surgery. METHODS: We retrospectively evaluated 1,350 breast cancer patients with relapses after curative surgery between 1998 and 2012 from referral centers in Turkey. Patients were divided into 4 biological subtypes according to immunohistochemistry and grade: triple negative, HER2 overexpressing, luminal A and luminal B. RESULTS: The percentages of patients with luminal A, luminal B, HER2-overexpressing, and triple-negative breast cancer were 32.9% (n = 444), 34.9% (n = 471), 12.0% (n = 162), and 20.2% (n = 273), respectively. The distribution of metastases differed among the subgroups: bone (66.2% and 53.9% in luminal A and B vs. 38.9% in HER2-overexpressing and 45.1% in triple negative, p < 0.001), liver (40.1% in HER2-overexpressing vs. 24.5% in luminal A, 33.5% in luminal B, and 27.5% in triple negative, p < 0.001), lung (41.4% in triple negative and 35.2% in HER2-overexpressing vs. 30.2% and 30.6% in luminal A and B, p = 0.008) and brain (25.3% in HER2-overexpressing and 23.1% in triple negative vs. 10.1% and 15.1% in luminal A and B, p < 0.001). CONCLUSIONS: Organ-specific metastasis may depend on the molecular subtype of breast cancer. Tailored strategies against distant metastasis concerning the molecular subtypes in breast cancer should be considered

Tailored strategies against distant metastasis concerning the molecular subtypes in breast cancer should be considered. (C) 2016 S. Karger GmbH, Freiburg
Biological Subtypes and Distant Relapse Pattern in Breast Cancer Patients After Curative Surgery (Study of Anatolian Society of Medical Oncology)
Purpose: The aim of the study was to investigate the association between
the molecular subtypes and patterns of relapse in breast cancer patients
who had undergone curative surgery. Methods: We retrospectively
evaluated 1,350 breast cancer patients with relapses after curative
surgery between 1998 and 2012 from referral centers in Turkey. Patients
were divided into 4 biological subtypes according to
immunohistochennistry and grade: triple negative, HER2 overexpressing,
luminal A and luminal B. Results: The percentages of patients with
luminal A, lumina! B, HER2-overexpressing, and triple-negative breast
cancer were 32.9\% (n = 444), 34.9\% (n = 471), 12.0\% (n = 162), and
20.2\% (n = 273), respectively. The distribution of metastases differed
among the subgroups: bone (66.2\% and 53.9\% in lumina! A and B vs.
38.9\% in HER2-overexpressing and 45.1\% in triple negative, p < 0.001),
liver (40.1\% in HER2-overexpressing vs. 24.5\% in lumina! A, 33.5\% in
luminal B, and 27.5\% in triple negative, p < 0.001), lung (41.4\% in
triple negative and 35.2\% in HER2-overexpressing vs. 30.2\% and 30.6\%
in luminal A and B, p = 0.008) and brain (25.3\% in HER2overexpressing
and 23.1\% in triple negative vs. 10.1\% and 15.1\% in lumina! A and B,
p < 0.001). Conclusions: Organ -specific metastasis may depend on the
molecular subtype of breast cancer. Tailored strategies against distant
metastasis concerning the molecular subtypes in breast cancer should be
considered. (C) 2016 S. Karger GmbH, Freiburg
