Publication Metadata only Clinical outcome of breast cancer patients with N3a (>= 10 positive lymph nodes) disease: has it changed over years?(HUMANA PRESS INC, 2011) DANE, FAYSAL; Basaran, Gul; Devrim, Cabuk; Caglar, Hale B.; Gulluoglu, Bahadir; Kaya, Handan; Seber, Selcuk; Korkmaz, Taner; Telli, Ferhat; Kocak, Muharrem; Dane, Faysal; Yumuk, Fulden P.; Turhal, Serdar N.It has been shown that breast cancer patients with N3a (10 positive lymph nodes) had a poor prognosis. We planned to investigate the clinical outcome BC patients who presented with N3a disease and had no evidence of systemic metastasis at the time of diagnosis. We made a retrospective chart review of breast cancer patients who had a parts per thousand yen10 positive lymph nodes and received adjuvant systemic therapy in Marmara University Hospital between 1998 and 2008. We recorded clinical, pathologic and treatment characteristics of the patients and analyzed the survival outcome. We identified 73 patients with N3a disease who were treated in Marmara University Hospital between 1998 and 2008. The median age was 52. Most (75%) of the patients had invasive ductal histology, 75% had T2/T3 tumors, 36% had grade 3 tumors. The median number of metastatic lymph nodes was 15. Estrogen and progesterone receptors were both positive in 61% and both negative in 16+ tumors. Her-2/neu status was assessed in 68% of the tumors; 18% of patients had 3+ and 50% had negative scores. Six patients had triple negative tumors. All patients except one received adjuvant chemotherapy and radiotherapy. Seventy-four percent of patients received anthracycline/taxane-based chemotherapy. Fifty-nine patients received adjuvant endocrine therapy, 42% them received aromatase inhibitors. Five of the 13 Her-2 positive patients received adjuvant trastuzumab. With a median follow-up of 47 months, 5-year disease and overall survival rates were 66 and 81%, respectively. Twenty-four patients had relapsed and 14 patients died. Her-2 status and the number of lymph nodes (< 20 vs. a parts per thousand yen20) had significant impact on disease-free survival in the univariate analysis (P = 0.03 and 0.05, respectively) and Her-2 retained its significant impact on disease-free survival in the multivariate analysis (P = 0.05). The prognosis of BC patients with N3a disease has changed favorably in the past decade with the current standards of care.Publication Open Access Is insulin resistance a predictor for complete response in breast cancer patients who underwent neoadjuvant treatment?(BMC, 2020-12) DANE, FAYSAL; Alan, Ozkan; Akin Telli, Tugba; Aktas, Bilge; Koca, Sinan; Okten, Ilker Nihat; Hasanov, Rahib; Basoglu, Tugba; Arikan, Rukiye; Demircan, Nazim Can; Ercelep, Ozlem; Kaya, Serap; Ugurlu, Mustafa Umit; Kaya, Handan; Akgul Babacan, Nalan; Dane, Faysal; Yumuk, Perran FuldenPurpose Neoadjuvant chemotherapy is the standard front-line treatment modality in locally advanced breast cancer. Achieving pathological complete response (pCR) is a significant prognostic factor for prolonged disease-free and overall survival. Insulin resistance is defined as a pathological condition in which insulin effect is impaired in peripheral target tissues such as the skeletal muscle, liver, and adipose tissue. The relationship between breast cancer and insulin resistance is controversial. In this study, our aim is to evaluate the role of insulin resistance, body mass index (BMI), metabolic syndrome, and inflammation markers to predict complete response in breast cancer patients who underwent neoadjuvant treatment. Methods Data from 55 locally advanced non-diabetic breast cancer patients, treated with neoadjuvant chemotherapy between 2015 and 2017, were retrospectively evaluated. Homeostatic model assessment, IR = insulin resistance (HOMA-IR) was calculated by using the obtained insulin and fasting blood glucose values before neoadjuvant chemotherapy (fasting insulin x fasting glucose/405). We considered a cut-off of 2.5 for insulin resistance. The systemic inflammatory index (SII), neutrophil-lymphocyte ratio (NLR), and platelet-lymphocyte ratio (PLR) were calculated. Results Twenty-five patients had no insulin resistance. The most common pathologic subtype (56%) was hormone receptor (HR) positive and human epidermal growth factor receptor-2 (Her-2)-negative invasive ductal carcinoma. Sixteen (29%) patients had a pathological complete response (pCR). We found that the probability of pCR in patients with insulin resistance was 4.7 times lower than that in patients without insulin resistance [OR: 4.7 (95%CI 1.7-17.2),p= 0.01]. Conclusion Our results revealed that insulin resistance may have a negative effect on pathological complete response (pCR) following neoadjuvant therapy particularly with hormone-positive and Her-2-negative cases of non-diabetic breast cancer.Publication Metadata only A case of primary squamous cell carcinoma of the breast with pathologic complete response after neoadjuvant chemotherapy(MOSBY-ELSEVIER, 2019) KAYA, HANDAN; Alan, Ozkan; Telli, Tugba Akin; Ercelep, Ozlem; Hasanov, Rahib; Simsek, Eda Tanrikulu; Mutis, Aydan; Ones, Tunc; Kaya, Handan; Yumuk, Perran FuldenBackground: Primary squamous cell carcinoma (SCC) of the breast is a metaplastic carcinoma subtype which includes fibromatosis-like and sarcomatoid features. This is a very aggressive tumor with poor prognosis. Other sites of primary SCC should be ruled out first to classify these tumors as primary SCC of the breast. Here we present a case of locally advanced primary SCC of the breast. Case Report: A 72 years old woman presented with a right axillary lump. Trucut biopsy was performed, it showed squamous cell carcinoma. Estrogen receptor had poor immunoreactivity, negative for both progesteron receptor and HER 2 in immunohistochemistry staining. PETCT imaging were conducted to showing only 6 x 6.5 cm mass in right breast adjacent to axilla, multiple lymphadenomegaly in right axillary. We planned neoadjuvant chemotherapy consisting of weekly paclitaxel followed by epirubicin and cyclophosphamide combination. Postoperative pathology revealed wide necrosis, no viable tumor cell. We started adjuvant anastrozole treatment of 1 mg/day. No evidence of disease was detected after 1 year follow up. Conclusion: Primary squamous cell carcinoma of the breast is a very rare disease with no standard treatment approach. Our case achieved pathologic complete response after neoadjuvant chemotherapy.
