Introduction: The relation between Behçet's disease (BD) and breast cancer (BC) is unclear. Our purpose is to investigate whether BD has an important effect on BC or vice versa.
Patients And Methods: A total of 12 female BC patients with a diagnosis of BD were identified from a cohort including 5050 BC patients.
Background: Body mass index (BMI) is defined as a poor prognostic factor in patients with breast cancer (BC). However, there are controversial results regarding the various effects of BMI on BC, hence the exact pathophysiology of the relation between obesity and BC is still under debate, and remains unclear. This paper aims to investigate the association between BMI at presentation and BC subtypes defined according to the immunohistochemical classification in both premenopausal and postmenopausal patients with BC.

Therefore, axillary, subclavicular, internal mammary or supraclavicular nodal involvement is a crucial step before metastasis. Anatomical differences between the right and left lymphatic drainages of the breasts may significantly affect the rate, site and time to development of distant metastasis.

To establish this, we compared 1-year and 9-week trastuzumab regimens in HER2-positive, lymph node-negative early-stage breast cancer patients.
Methods: We retrospectively analyzed 4374 breast cancer patients.
Purpose: The relation between higher body mass index (BMI) and pathological complete response (pCR) to neoadjuvant chemotherapy (NAC) in breast cancer (BC) is a controversial issue according to the data of Western and Asian patients. The aim of this study is to evaluate BMI and pCR to NAC and discuss the importance of pCR outcomes in Turkish BC patients as a bridging country between Europe and Asia.
Patients And Methods: Of the 4423 BC patients diagnosed between the years 1994 and 2015 in Hacettepe University Cancer Institute, 295 female patients with stage II and III BC were enrolled in the study.
Purpose: Eribulin is a non-taxane microtubule inhibitor, which can be used after anthracycline and taxane treatment in patients with metastatic breast cancer (MBC). The purpose of this study was to investigate the efficacy and safety of eribulin monotherapy in heavily pretreated MBC patients.
Methods: In this single-center trial, a total of 66 MBC patients who received eribulin monotherapy in Hacettepe University Cancer Institute between 2013 and 2015 were retrospectively analyzed.
Purpose: Obesity is a well known risk factor for breast cancer recurrence and poor prognosis. We studied the effect of body mass index (BMI) on recurrence pattern in early breast cancer patients.
Methods: This retrospective cross-sectional study analyzed the data of 2731 early stage breast cancer patients.
Purpose: The purpose of this study was to investigate the frequency and prognosis of inflammatory breast cancer (IBC) according to molecular subtypes.
Methods: Demographic data were examined for 78 patients diagnosed with IBC among breast cancer patients monitored in our clinic. Patients were staged according to the 2010 AJCC guidelines.
Purpose: To compare the effectiveness of adjuvant chemotherapy regimens in triple negative breast cancer (TNBC) for which no protocol has been determined to be treatment of choice.
Methods: In this single-center retrospective trial, we analyzed the adjuvant regimens of 164 TNBC patients among 3253 breast cancer patient records. Adjuvant TAC (docetaxel, doxorubicin, cyclophosphamide), CAF (cyclophosphamide, doxorubicin, 5fluorouracil), and AC-T (doxorubicin, cyclophosphamide followed by docetaxel) regimens were compared in terms of disease free survival (DFS) and overall survival (OS).
Physical inactivity may an important outcome in the prognosis of breast cancer. Physical activity levels decrease significantly for breast cancer patients following the treatment and remain low after oncology treatment is completed. The aim of this study was to determine physical activity levels and to examine associations among physical activity, comorbidity, functional capacity, peripheral muscle strength, and psychosocial status in breast cancer patients.

Material And Methods: A total of 52 patients with a diagnosis of breast cancer were included in the study. The patients were randomly assigned to 2 groups: aerobic exercise (n = 28) and yoga added to aerobic exercise (n = 24).
Objectives: In this study, we tried to evaluate the efficacy of locoregional treatment (LRT) in patients with metastatic breast carcinoma (MBC).
Materials And Methods: The medical records of 227 patients with MBC at initial presentation between April 1999 and January 2013 were retrospectively evaluated. The median age at diagnosis was 50 years (range, 27-83 years).
The aim of this study is to evaluate clinicopathologic characteristics and the multi-disciplinary treatment results of metaplastic breast cancer (MBC) patients treated in a single institute. Seventeen female patients with MBC treated in our department between June 2000 and January 2012 were identified and retrospectively evaluated. The median age at diagnosis was 46 years (range, 26-66 years).

This study aims to assess the effects of tamoxifen and aromatase inhibitors (Als) on quality of life (QoL) and cognitive functions in breast cancer patients.
Patients And Methods: The study included 101 patients receiving tamoxifen, 97 patients receiving Als, and 95 patients without any ET.
Background: Hodgkin's lymphoma (HL) is a B cell lymphoma characterized by the presence of Reed-Sternberg cells. HL comprises 1% of all cancer cases and 14% of all lymphoma cases.
Aims: We designed a retrospective study to investigate the clinical features and prognostic factors of HL patients diagnosed at an experienced oncology centre.
Background. Although patients with Hodgkin's lymphoma (HL) achieve prolonged survival, long-term complications are a major cause of morbidity and mortality among long-term survivors of HL. Methods.

Gene expression profiling studies have classified breast cancers into five subtypes: luminal A, luminal B, HER-2 overexpressing, basal-like, and normal breast-like. Although clinical differences between subtypes have been well described in the literature, etiologic heterogeneity have not been fully studied.

However, their significance in different subtypes of breast cancer is still under investigation. The aim of this study was to study the effects of AR on clinicopathological features and prognosis in patients with estrogen and progesterone receptor (ER/PR)-negative, HER2-positive breast cancer.

Aims: This study was performed to analyse adnexal masses among women with breast cancer with regard to variables predictive of malignancy.
Methods: The study included women with breast cancer who had undergone surgery for an adnexal mass between 2002 and 2010 at Hacettepe University Hospital.
It has been reported previously that: (1) normal-breast epithelial cells that are CD24-/44+ express higher levels of stem/progenitor cell-associated genes; (2) cancer cells that have undergone epithelial to mesenchymal transition display CD24-/44+ cell-surface expression, a marker for breast cancer stem cells; (3) loss of E-cadherin is a preliminary step in epithelial to mesenchymal transition; and (4) vimentin is a marker of mesenchymal phenotype. We hypothesized that stem cell subpopulations would be more frequent in metastatic than in primary tumors. Therefore we assessed by immunohistochemical analysis, tissue microarrays containing tissue from primary and associated metastatic breast cancers for expression of CD24, CD44, E-cadherin and vimentin to evaluate candidate cancer-initiating cell populations in breast cancer subtypes and metastatic lesions.

It is metabolized to its active form 5-fluoruracil by the enzyme thymidine phosphorylase, which exists in higher concentrations in tumor tissue and liver than in normal tissues. In the study, we investigated the changes in mean corpuscular volume (MCV) of red blood cells and the possible correlation of these changes with the clinical outcome of capecitabine treatment in women with metastatic breast cancer.
