Öğe Association of MicroRNA 211 expression with prognosis in colorectal cancer: A case-control study(Lippincott Williams & Wilkins, 2014) Sumbul, Ahmet Taner; Gogebakan, Bulent; Oztuzcu, Serdar; Yengil, Erhan; Sezer, Ahmet; Aball, Huseyin[Abstract Not Available]Öğe Association of response to first-line chemotherapy with the efficacy of atezolizumab in patients with metastatic urothelial carcinoma.(Lippincott Williams & Wilkins, 2021) Tural, Deniz; Olmez, Omer Fatih; Sumbul, Ahmet Taner; Artac, Mehmet; Ozhan, Nail; Akar, Emre; Cakar, Burcu[Abstract Not Available]Öğe Being a medical oncologist near the war area(Zerbinis Medical Publ, 2014) Sumbul, Ahmet Taner; Sezer, Ahmet; Tonyali, Onder; Ozturk, Mehmet Akif; Abali, Huseyin; Ozyilkan, Ozgur[Abstract Not Available]Öğe Can serial monitoring of serum Vascular Endothelial Growth Factor (VEGF), Nitric Oxide (NO), and Angiotensin II (ANGII) levels have predictive role during Bevacizumab treatment?(Int Scientific Information, Inc, 2014) Sumbul, Ahmet Taner; Disel, Umut; Sezgin, Nurzen; Sezer, Ahmet; Kose, Fatih; Besen, Ali Ayberk; Sumbul, ZehraBackground: Standard treatment of colorectal cancer includes both cytostatic chemotherapy and targeted therapies. Bevacizumab, targeting the VEGF receptor, is one of the primary targeted therapies that achieve better response rate and survival rate as compared to combination chemotherapy. To the best of our knowledge, there is no established single marker that can be used as a predictive marker in bevacizumab therapy. Material/Methods: We enrolled 24 patients with the diagnosis of metastatic colorectal cancer in our study. During the study, 2 blood samples were drawn from patients before the first cycle and after the sixth cycle of bevacizumab therapy. Serum levels of VEGF, ANG II, and NO were recorded. Results: While the change across VEGF levels was found to be a statistically significant decreasing trend (p=0.009), this decrease was not found to be correlated with treatment response and hypertension development. Additionally, no statistically significant difference was found in terms of NO and ANG II levels. Conclusions: This study showed a significant decrease in serum VEGF, but failed to show a significant change in NO and ANG II levels during bevacizumab treatment. Although no significant correlation was found between the presence of hypertension and markers, most patients (83%) had an increase in their blood pressure. Our results suggest that dynamic monitoring of NO and ANG II, along with VEGF, may not be useful as predictive markers for bevacizumab treatment in colorectal cancer.Öğe A case of rectal adenocarcinoma presented with palatine tonsil metastasis(Sage Publications Ltd, 2016) Tonyali, Onder; Sumbul, Ahmet Taner; Ozturk, Mehmet Akif; Koyuncuer, Ali; Ekiz, FuatThe most common metastatic sites of colorectal cancer are liver, lung, peritoneum and lymph nodes. Metastasis of colorectal carcinoma to palatine tonsil is rarely seen. To our knowledge, only 11 patients were documented in English literature. Atypical metastases can sometimes lead to misdiagnosis. Precise diagnosis of atypical metastases requires a careful physical examination, good imaging method and comprehensive pathological evaluation. Here, we report a case of rectal adenocarcinoma presented with palatine tonsil metastasis.Öğe Clinicohistopathological features and treatment outcomes in testicular lymphomas: A single center experience.(Amer Soc Clinical Oncology, 2018) Sedef, Ali Murat; Kocer, Nazim Emrah; Besen, Ali Ayberk; Mertsoylu, Huseyin; Sezer, Ahmet; Sumbul, Ahmet Taner; Kose, Fatih[Abstract Not Available]Öğe Concurrent Chemoradiotherapy with Vinorelbine plus Split-Dose Cisplatin may be an Option in Inoperable Stage III Non-Small Cell Lung Cancer: A Single-Center Experience(Int Scientific Information, Inc, 2015) Mertsoylu, Huseyin; Kose, Fatih; Sumbul, Ahmet Taner; Sedef, Ali Murat; Dogan, Ozlem; Besen, Ali Ayberk; Parlak, CemBackground: Concurrent chemoradiotherapy is the current standard treatment for inoperable stage III non-small cell lung cancer (NSCLC). In this study we aimed to investigate the efficacy and toxicity of CCRT with split dose of cisplatin (30 mg/m(2)) and vinorelbine (20 mg/m(2)) in patients with inoperable stage III NSCLC followed in our oncology clinic. Material/Methods: Medical records of 97 patients with inoperable stage III NSCLC treated with concurrent chemoradiotherapy with cisplatin-vinorelbine were retrospectively analyzed. Cisplatin (30 mg/m(2)) and vinorelbine (20 mg/m(2)) were administered on days 1, 8, 22, and 29 during radiotherapy. Two cycles of consolidation chemotherapy were given. All patient data, including pathological, clinical, radiological, biochemical, and hematological data, were assessed retrospectively using our database system. Results: Our study included 97 unresectable stage III NSCLC patients who were treated with CCRT. Median age was 58 years old (range 39-75) and 87 (89.7%) of the patients were men. ECOG performance score was 0-1 in 93 patients (95.9%). Squamous histology, the most common histology, was diagnosed in 46 patients (47.4%). Median follow-up time was 23.8 months. Median progression-free survival (PFS) and median overall survival time (OS) were 10.3 months and 17.8 months, respectively. Objective response rate and clinical benefit rate were 75.3% and 83.5%, respectively. Distant and local relapse rate were 57.1% and 42.9%, respectively. Hematological and non-hematological grade 3-4 toxicities were seen in 13 (13.4%) and 16 (16.5%) patients, respectively. Six (6.1%) patients died due to toxicity. Conclusions: The results of this study suggest that split-dose cisplatin may offer fewer grade III-IV toxicities without sacrificing efficacy and could be an option in patients with inoperable stage III NSCLC during CCRT. Similar to past studies, despite high response rate during CCRT, distant relapse is the major parameter that influences patient survival in long-term in NSCLC.Öğe Continuous distress in an Oncology Clinic in Turkey: Should we make use of the distress thermometer mandatory as a precautionary measure for physicians?(Zerbinis Medical Publ, 2014) Sumbul, Ahmet Taner; Sezer, Ahmet; Abali, Huseyin; Dicel, Umut; Gultepe, Ilhami; Besen, Ali Ayberk; Ozyilkan, OzgurPurpose: To study the data on the distress scale points (DSP) of patients in oncology clinics in relation to age, the reasons for admission to the hospital, the educational status and the family support. Methods: Six hundred and fifty three patients diagnosed with malignancies were enrolled. All of the patients were asked to fill in a questionnaire that included data about their demographic characteristics, diagnoses, the cause of hospital admission and the educational status. The family support of each patient was observed and noted by clinicians and other healthcare providers during the clinical visits. Results: The mean patient age was 54.8 years (+/- SD 13.7). Of the patients 314 (48.1%) were male and 339 (51.9%) female. The median DSP for the group that included patients <35 years of age was 3; this was 5 for the 36-49 age group, 4 for the 50-69 age group and 4.5 for the >70 age group. A statistically significant difference in DSP between these groups was noticed (p=0.035). The DSP for patients <35 years of age was lower than that of the other age groups. The median DSP for the patients presenting to the outpatient clinic for adjuvant therapy was 5; this was 5 for patients presenting for palliative therapy, and 3 in the active surveillance group, and a statistically significant relationship was determined between the DSP and the reason for admission to the outpatient clinic (p<0.001). The patients that had presented to the outpatient clinic for active surveillance had statistically significantly lower DSP compared to the other groups (p<0.05). Conclusions: Distress in oncology clinics seems to be continuous; thus, the use of distress thermometer as a precautionary measure for distress development in patients with malignancies should be mandatory to help medical oncologists understand the psychosocial needs of their patients and start to treat them as a human beings.Öğe Determination of Phthalates Migrating from Plastic Containers into Beverages(Springer, 2015) Ustun, Ihsan; Sungur, Sana; Okur, Ramazan; Sumbul, Ahmet Taner; Oktar, Suleyman; Yilmaz, Nigar; Gokce, CumaliThe determination of phthalates in beverages (soda, lemonade, cola, mineral water) sold in Turkish markets was carried out using gas chromatography-mass spectrometry (GC-MS). The mean phthalate concentrations were determined to be between 0.095 and 0.633 mg/L in soda, 0.018 and 1.219 mg/L in lemonade, 0.019 and 1.123 mg/L in cola, and 0.085 and 0.312 mg/L in mineral water. bis(2-Ethylhexyl) phthalate (DEHP) showed the highest level of migration into beverages. Furthermore, the influence of the type of preservative (sodium benzoate, potassium sorbate, sodium benzoate + potassium sorbate) and storage time were determined.Öğe Does cyclin E and p57kip2 expression have prognostic and survival value in colorectal adenocarcinoma?(E-Century Publishing Corp, 2018) Ozgur, Tumay; Sumbul, Ahmet Taner; Yaldiz, Mehmet; Temiz, Muhyittin; Akdag, AbdurrahmanIntroduction: Colorectal cancer is still one of the main causes of cancer death in the world. There is a continous need for novel biomarkers for diagnose, treatment modalities and follow-up. Cyclin E and p57(KIP2) as the positive and negative regulators of cell cycle seem to be an important target for investigations. Materials and methods: In a retrospective setting, primary colorectal adenocarcinoma cases examined in Mustafa Kemal University, School of Medicine, Pathology Department between 2008-2015 were reviewed. Immunohistochemical expressions of cyclin E and p57(KIP2) in 80 pairs of colorectal carcinoma and adjacent normal mucosal tissues were evaluated and the findings were compared with clinicopathological parameters and survival time. Results: There were no statistically significant difference between two groups both in cyclin E and p57(KIP2) stained tissues (P>0.05). There were 40 (50%) patients in high-expression group and 40 (50%) patients in low-expression group for cyclin E. P57(KIP2) was negative in 55 (68.75%) patients and positive in 25 (31.75%) patients. There were no statistically significant relation between p57(KIP2) and cyclin E expressions with clinicopathologic parameters defined as age, gender, lymphovascular invasion, perineural invasion, depth of invasion, nodal involvement, emergency in operation, perforation before operation and overall survival except that there was significant relation between p57(KIP2) expression and histological grade (P=0.012). Conclusions: Immunohistochemical studies of cyclin E and p57(KIP2) should be performed with larger series of patients supported by more detailed technical research methods to be candidates as predictive markers for treatment modalities and prognostic factors.Öğe Ductal Adenocarcinoma: A Rare Entity of Prostate Gland in a Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma Patient(Derman Medical Publ, 2015) Ozgur, Tumay; Rifaioglu, Murat Mehmet; Sumbul, Ahmet Taner; Aydogan, Fusun; Atci, NesrinProstate cancer is the most common malignancy in men and ductal adenocarcinoma is a pathologic subtype with specific histological and clinical features. Seventy-six year-old male patient with chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) admitted to our hospital with lower urinary tract symptoms. The last prostate specific antigen (PSA) level was 26 ng/ml and serial transrectal ultrasound guided biopsies were administered and benign prostate hyperplasia and non-specific prostatitis were the results of pathology reports. Due to the persistence of the symptoms transurethral resection of the prostate was performed. In the pathologic evaluation of the material adenocarcinoma focuses without stroma has been observed between the hyperplasic prostate tissues. The tumor has been diagnosed as ductal adenocarcinoma with 4 + 4 Gleason pattern score. Bone scintigraphy was revealed activity uptake on lomber vertebral column due to metastasis. Computerized tomography was revealed previous bilateral inguinal and right iliac lymphadenopathy due to CLL/SLL. Total androgen deprivation therapy and bilateral orchiectomy was applied. After three mounts according to biochemical and imaging results, radiotherapy cure began. Ductal adenocarcinoma is a rare subtype of prostate carcinoma with clinical behavior from that seen in conventional adenocarcinoma. On the other hand it is worth to point out the occurence of this entity as second malignancy during follow-up of CLL/SLL.Öğe EFFECT OF GM-CSF LEVELS ON OSTEOPOROSIS IN POSTMENOPAUSAL PERIOD(Carbone Editore, 2014) Yagiz, Abdullah Erman; Dokuyucu, Recep; Sumbul, Ahmet Taner; Yengil, Erhan; Ustun, Nilgul; Koca, Irfan; Gogebakan, BulentObjectives: Cytokines and hematopoietic growth factors may play a role in the pathogenesis of osteoporosis. The aim of this study was to assess the relationship between osteoporosis (OP) and granulocyte-macrophage colony stimulating factor (GM-CSF) in postmenopausal period. Materials and methods: Total number of 80 female patients between the ages of 45-75 and who had entered in menopause from at least one year and diagnosed with OP were enrolled in this study. As a control group, 80 healthy volunteer female patients who had entered in menopause from at least one year and had no diagnosis of OP were selected. The age, height, weight, body mass index, duration of menopause, exercise habits of the patients and controls were recorded and bone mineral density was measured for the diagnosis of OP. The serum GM-CSF concentrations of individuals were quantified using a specific enzyme immunoassay kit. Results: There was no significant relationship between the mean age, duration of menopause and body mass index of patients and controls (p>0.05). Serum GM-CSF levels of patients and control groups did not differ significantly (p> 0.05). Conclusion: The results of our study showed that there was no significant correlation between osteoporosis and serum GMCSF levels. Osteoporosis might be correlating with the levels of GM-CSF in bone microenvironment rather than serum levels.Öğe Effect of GM-CSF levels on osteoporosis in postmenopausal period(Acta Medica Mediterranea, 2014) Yagiz, Abdullah Erman; Dokuyucu, Recep; Sumbul, Ahmet Taner; Yengil, Erhan; Ustun, Nilgul; Koca, Irfan; Gogebakan, BulentObjectives: Cytokines and hematopoietic growth factors may play a role in the pathogenesis of osteoporosis.

A common functional single nucleotide polymorphism (SNP) rs920778 (T -> aEuro parts per thousand C) in the intronic enhancer of the HOTAIR has been reported to influence HOTAIR expression and cancer predisposition, but the association of HOTAIR rs920778 polymorphism with BC susceptibility and clinicopathological features has yet to be investigated. We genotyped HOTAIR rs920778 polymorphism in 245 Turkish women including 123 BC patients and 122 age-matched healthy controls by a real-time polymerase chain reaction (PCR) with the TaqMan assay. We found that the CC genotype of HOTAIR rs920778 polymorphism significantly increased the risk of BC in both codominant (odds ratio (OR) = 2.12, 95 % confidence interval (CI) 1.00-4.51, P = 0.05) and recessive (OR = 2.40, 95 % CI 1.22-4.73, P = 0.01) inheritance genetic models. Our research also indicated an association between the CC genotype of HOTAIR rs920778 polymorphism and clinicopathologic features of tumor, including advanced tumor-node-metastasis (TNM) stage, larger tumor size, distant metastasis, and poor histological grade (P < 0.05). Because our findings suggest for the first time that the CC genotype of HOTAIR rs920778 polymorphism might play important roles in genetic susceptibility to BC development and aggressiveness in a Turkish population, further independent studies are required to validate our findings in a larger series, as well as in patients of different populations.Öğe Evaluation of mean platelet volume in patients with type 2 diabetes mellitus and blood glucose regulation: a marker for atherosclerosis?(E-Century Publishing Corp, 2014) Ulutas, Kemal Turker; Dokuyucu, Recep; Sefil, Fatih; Yengil, Erhan; Sumbul, Ahmet Taner; Rizaoglu, Hatice; Ustun, IhsanObjective: Platelets have an important role in atherosclerosis and arterial thrombosis. Cardiovascular complication prevalence of type 2 diabetes mellitus (type 2 DM) may be associated with glycosylated hemoglobin (HbA(1c)) and mean platelet volume (MPV). The aim of the study was to investigate if platelets were activated in diabetes and its associated vascular complications by measuring the MPV in the diabetics compared to the non-diabetics, and to determine the correlation of MPV with fasting serum glucose (FSG), HbA(1c) and duration of diabetes in the diabetic patients, respectively. Materials and Methods: The study carried out in 65 patients with type 2 DM and 40 non-diabetic subjects. In addition to non-diabetic patients, all diabetic patients were divided into two groups according to their HbA(1c) levels: group A consisted of patients with HbA(1c) levels <= 7% and group B consisted of patients with HbA(1c) levels >7%. Results: MPV was significantly higher in Group B as compared to both non-diabetics and Group A. MPV had a high positive correlation with HbA(1c) and FSG, as with diabetes duration. It is found that MPV was increased in type 2 DM. Conclusion: Our findings suggested an association between MPV and HbA(1c). Therefore, MPV would be a beneficial prognostic marker of cardio-vascular complications in patients with type 2 DM.Öğe A functional HOTAIR rs920778 polymorphism does not contributes to gastric cancer in a Turkish population: a case-control study(Springer, 2015) Bayram, Suleyman; Ulger, Yakup; Sumbul, Ahmet Taner; Kaya, Berrin Yalinbas; Rencuzogullari, Ahmet; Genc, Ahmet; Sevgiler, YusufAn aberrant up-regulation of HOX transcript antisense intergenic RNA (HOTAIR), a long non-coding RNA (lncRNA), is associated with human cancers including gastric cancer (GC) and worse clinicopathological features. A naturally occurring functional single nucleotide polymorphism (SNP) rs920,778 (C -> T) in the intronic enhancer of HOTAIR gene has been demonstrated to affect HOTAIR expression and cancer susceptibility. To investigate the association of the HOTAIR rs920778 polymorphism on the risk of GC susceptibility in Turkish population, a hospital-based case-control study was carried out consisting of 104 GC and 209 healthy control subjects matched on age and gender. The genotype frequency of HOTAIR rs920778 polymorphism was determined by using TaqMan Real-Time Polymerase Chain Reaction. No statistically significant differences were found in the allele or genotype distributions of the HOTAIR rs920778 polymorphism among GC and healthy control subjects (P > 0.05). Our results demonstrate that the HOTAIR rs920778 polymorphism has not been in any major role in genetic susceptibility to gastric carcinogenesis, at least in the population studied here. Independent studies are needed to validate our findings in a larger series, as well as in patients of different ethnic origins.Öğe Gemcitabine plus Platinum Combination Chemotherapy in Patients with Metastatic Cancer who suffer from Severe and Irreversible Hepatic Impairment: A Single Center Experience(H G E Update Medical Publishing S A, 2014) Sezer, Ahmet; Sumbul, Ahmet Taner; Abali, Huseyin; Mertsoylu, Huseyin; Muallaoglu, Sadik; Kose, Fatih; Ozyilkan, OzgurThere is limited information on chemotherapeutic agent doses suitable for patients with metastatic cancer who suffer from and irreversible hepatic impairment and who could potentially benefit from chemotherapy and on their results. In this retrospective study, we aimed to share our center's experience of Gemcitabine + Platinum Combination chemotherapy in these patients. Data of 13 patients matching the criteria were analyzed. In our study the patients were treated with a dose of Gemcitabine + Platinum Combination, 50% of the original dose and the dose was increased gradually on the following days. Thirteen of one patient was given Gemcitabine & Carboplatin protocol and the others were given Gemcitabine & Cisplatin. In 42 chemotherapy cycles in total grade 3-4 thrombocytopenia occure after 7 cycles, grade 3-4 neutropenia was not observed While liver functions in 8 patients improved slightly, no change was observed in 2 patients and in 3 patients they deteriorated. Total survival period was calculate as 3.78 (95CI%: 0,17-7.54) months. As a consequence Gemcitabine + Platinum Combination chemotherapy in patients with metastatic cancer who suffer from severe and irreversible hepatic impairment can be implemented when clinical benefits are expected.Öğe Investigation of neutrophil lymphocyte ratio and blood glucose regulation in patients with type 2 diabetes mellitus(Sage Publications Ltd, 2014) Sefil, Fatih; Ulutas, Kemal Turker; Dokuyucu, Recep; Sumbul, Ahmet Taner; Yengil, Erhan; Yagiz, Abdullah Erman; Yula, ErkanObjective Leukocytosis is thought to be directly associated with the pathogenesis of atherosclerosis and metabolic syndrome. Increased white blood cell (WBC) count is related to cardiovascular disease in patients with type 2 diabetes mellitus; raised neutrophil lymphocyte ratio (NLR) is associated with metabolic syndrome. There is little information, however, concerning a correlation between glycosylated haemoglobin (HbA(1c)) and NLR. The aim of the present study was to investigate the relationship between NLR and blood glucose regulation. Methods This retrospective study was conducted in patients with type 2 diabetes mellitus, divided into two groups according to HbA(1c) levels: group 1, HbA(1c) levels7%; group 2, HbA(1c) levels>7%. Venous WBC, neutrophil and lymphocyte counts were determined. Results Of 71 patients included, fasting serum glucose, neutrophil and WBC counts were significantly higher in group 2 compared with group 1. NLR had a positive correlation with HbA(1c). Conclusion There may be a significant relationship between NLR and blood glucose regulation. The authors propose that increased NLR may be associated with elevated HbA(1c) in patients with type 2 diabetes mellitus.Öğe Is it Rational to Continue Anti-Neoplastics with Minimal Toxicity even after Progression in Patients with no other Options? Possibly Yes(Asian Pacific Organization Cancer Prevention, 2014) Sezer, Ahmet; Sumbul, Ahmet Taner; Abali, Huseyin[Abstract Not Available]Öğe Low serum levels of vitamin D in metastatic cancer patients: a case-control study(Humana Press Inc, 2014) Sumbul, Ahmet Taner; Sezer, Ahmet; Kavvasoglu, Gamze; Batmaci, Celal Yucel; Yengil, Erhan; Yagiz, Abdullah Erman; Gultepe, IhamiAccompanying comorbidities observed during the cancer treatment usually affect the course and outcome of the therapy. Hypovitaminosis D, which is one of these conditions, is a resolvable problem, if recognized. In this study, we investigated whether the serum 25(OH) D levels of the patients who were presented to our outpatient clinic were different from the serum levels of the healthy population living in the same area. Our study included 90 patients who were presented to the Medical Oncology outpatient clinic and 90 age, gender, body mass index and ethnic origin matched controls without a known disease, who were presented to the outpatient clinics of the Departments of Internal Diseases and Family Medicine for routine controls. Blood count tests, detailed biochemistry tests (including serum levels of Cr, Ca and P), measurement of serum 25(OH) D levels and C-reactive protein were performed in serum samples of all of the patients and controls. Mean serum levels of 25(OH) D were 13.5 ng/ml (SD 5.1) in all cancer patients, 13.1 ng/ml (SD 4.2) in the patients who were presented for adjuvant therapy, 13.8 ng/ml (SD 5.5) in the patients who were presented at metastatic stage and 18.4 ng/ml (SD 12.5) in the controls. Mean serum CRP levels were 5.4 mg/dl (SD 1.2) in the control group, 8.4 mg/dl (SD 4.3) in the adjuvant therapy group and 20.3 (SD 16.8) in the patients with metastatic disease. Generally, all cancer patients (p 0.003) and the patients with metastatic cancer (p 0.004) had lower serum 25(OH) D levels compared to controls, and there was an inverse correlation between serum 25(OH) D and CRP levels in patients with metastatic cancer (p 0.036). In metastatic cancer patients, hypovitaminosis D may be a comorbidity and it is recommended to consider during initial evaluation and follow-up. Because it might improve these patients quality of life and chemotherapy adherence.
