Objective: Angiogenesis represents a key element in the pathogenesis of malignancy. There are no robust data on prognostic factors for overall survival (OS) in patients with metastatic colorectal cancer treated with vascular endothelial growth factor (VEGF)-targeted therapy. The present study was conducted to establish a prognostic model for patients using an oxaliplatin-based or irinotecan-based chemotherapy plus bevacizumab in metastatic colorectal cancer. Methods: Baseline characteristics and outcomes on 170 patients treated with FOLFIRI or XELOX plus anti-VEGF therapy-naive metastatic colorectal cancer were collected from three Turkey cancer centers. Cox proportional hazards regression was used to identify independent prognostic factors for OS. Results: The median OS for the whole cohort was 19 months (95% CI, 14.3 to 23.6 months). Three of the seven adverse prognostic factors according to the Anatolian Society of Medical Oncology (ASMO) were independent predictors of short survival: serum lactate dehydrogenase (LDH) greater than the upper limit of normal (ULN; p<0.001); neutrophils greater than the ULN (p<0.0014); and progression free survival (PFS) less than 6 months (p =0.001). Conclusion: Serum LDH and neutrophil levels were the main prognostic factors in predicting survival, followed by PFS. This model validates incorporation of components of the ASMO model into patient care and clinical trials that use VEGF-targeting agents.

Verit, Fatma Ferda,Cetin, Orkun,Keskin, Seda,Akyol, Hurkan,Zebitay, Ali Galip The Korean Society for Reproductive Medicine 2019 Clinical and Experimental Reproductive Medicine Vol.46 No.1

Objective: Bilateral uterine artery ligation (UAL) is a fertility-preserving procedure used in women experiencing postpartum hemorrhage (PPH). However, the long-term effects of this procedure on ovarian function remain unclear. The aim of this study was to investigate whether bilateral UAL compromised ovarian reserve and ovarian blood supply. Methods: This prospective study included 49 women aged between 21 and 36 years who had undergone a cesarean section for obstetric indications. Of these, 25 underwent uterine bilateral UAL to control intractable atonic PPH. The control group consisted of 24 women who had not undergone bilateral UAL. Standard clinical parameters, the results of color Doppler screening, and ovarian reserve markers were assessed in all participants at 6 months after surgery. The clinical parameters included age, parity, cycle history, body mass index, and previous medication and/or surgery. Color Doppler screening findings included the pulsatility index (PI) and resistance index (RI) for both the uterine and ovarian arteries. The ovarian reserve markers included day 3 follicle-stimulating hormone (FSH) levels, antral follicle count, and $anti-M\ddot{u}llerian$ hormone (AMH) levels. Results: There were no significant differences in the ovarian reserve markers of day 3 FSH levels, antral follicle count, and AMH levels between the study and control groups (p> 0.05 for all). In addition, no significant differences were observed in the PI and RI indices of the uterine and ovarian arteries (p> 0.05 for all). Conclusion: In this study, we showed that bilateral UAL had no negative effects on ovarian reserve or ovarian blood supply, so this treatment should be used as a fertility preservation technique to avoid hysterectomy in patients experiencing PPH.

Bulent Eser,Bunyamin Kaplan,Ali Unal,Ozlem Canoz,Fevzi Altuntas,H. Ismail. Sari,Ozlem Er,Metin Ozkan,Can Kucuk,Makbule Arar,Sebnem Gursoy,Mustafa Cetin 연세대학교의과대학 2006 Yonsei medical journal Vol.47 No.1

We carried out a retrospective analysis of 74 patients who were presented to our center with histopathological diagnosis of primary gastro-intestinal non-Hodgkin's lymphoma between 1990 and 2001. All patients have been staged according to Lugano Staging System. For histopathological classification, International Working Formulation was applied. The treatment choice concerning the surgical or non-surgical management was decided by the initially acting physician. Treatment modalities were compared using the parameters of age, sex, histopathological results, stage, and the site of disease. Of the 74 patients, 31 werefemale and 43 were male, with a median age of 49 years (range 15-80). The stomach was the most common primary site and was seenin 51 of 74 patients (68.9%). The intermediate and high grade lymphomas constituted 91.9% of the all cases. In a median follow-up of 29 months (range 2-128), 20 out of 74 patients died. There was a three year overall survival rate in 65.4% of all patients. The three year overall survival rate was better in stage I and II1 patients who were treated with surgery plus chemotherapy (+/-RT) than those treated with chemotherapy alone (93.7% vs. 55.6%, p 0.05). The stage and presence of B symptoms affected the disease free survival and overall survival significantly, but the histopathologic grade only affected the overall survival. On the basis of these results, we suggest that surgicalresection is necessary before chemotherapy in early stage (stage I and II1) patients with gastrointestinal non-Hodgkin's lymphomas because of the significant survival advantage it would bring to the patient.

Ismihan Goze,Ahmet Alim,Senay Akkus Cetinus,Ali Cetin,Nedim Durmus,Ahmet Turan Atas,Nilufer Vural 한국식품영양과학회 2010 Journal of medicinal food Vol.13 No.3

The radical scavenging, antimicrobial, and antispasmodic activities and the composition of Origanum acutidens (Hand.-Mazz.) Ietswaart (Order Labiatte) essential oil were evaluated in vitro. Gas chromatography/mass spectrometry analysis of the oil resulted in the identification of 20 compounds, representing 93.61% of the oil; carvacrol (65%) was the main component. The sample was also subjected to a screening for antioxidant activity by using the 1,1-diphenyl-2-picrylhydrazyl and β-carotene/linoleic acid assays. The essential oil exhibited strong antioxidant activity. Using the agar disk diffusion method, antimicrobial activities of the essential oils were determined for nine microorganisms; antimicrobial activity was shown against eight of them. O. acutidens oil exhibited spontaneous contractions in rat ileum at the 100% level at 0.1mg/mL level.

Iclal Ozdemir Kol,Kenan Kaygusuz,Sinan Gursoy,Ali Cetin,Zeki Kahramanoglu,Fikret Ozkan,Caner Mimaroglu 대한의학회 2009 Journal of Korean medical science Vol.24 No.5

We designed a randomized, double-blinded study to determine the efficacy and safety of 0.5 ㎎/㎏ intravenous ephedrine for the prevention of hypotension during spinal anesthesia for cesarean delivery. Patients were randomly allocated into two groups: ephedrine group (n=21) and control group (n=21). Intravenous preload of 15 mL/㎏ lactated Ringer’s solution was given. Shortly after the spinal injection, ephedrine 0.5 ㎎/㎏ or saline was injected intravenous for 60 sec. The mean of highest and lowest heart rate in the ephedrine group was higher than those of control group (P<0.05). There were significant lower incidences of hypotension and nausea and vomiting in the ephedrine group compared with the control group (8 [38.1%] vs. 18 [85.7%]); (4 [19%] vs. 12 [57.1%], respectively) (P<0.05). The first rescue ephedrine time in the ephedrine group was significantly longer (14.9±7.1 min vs. 7.9±5.4 min) than that of the control group (P<0.05). Neonatal outcome were similar between the study groups. These findings suggest, the prophylactic bolus dose of 0.5 ㎎/㎏ intravenous ephedrine given at the time of intrathecal block after a crystalloid fluid preload, plus rescue boluses reduce the incidence of hypotension.

Bozkurt, Oktay,Berk, Veli,Kaplan, Muhammed Ali,Cetin, Bulent,Ozaslan, Ersin,Karaca, Halit,Inanc, Mevlude,Duran, Ayse Ocak,Ozkan, Metin Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.6

Background: Capecitabine is an oral fluoropyrimidine derivative which is frequently used alone or in combination regimens for the treatment of metastatic breast cancer. Although overall and progression free survivals have increased in recent years with the use of new generation drugs, predictive factors that would further improve the outcomes are needed. Previous studies have demonstrated the relation between post-treatment increase in mean corpuscular volume (MCV) and predicting therapy response as well as survival. The present study investigated the clinical impact of MCV elevation in metastatic breast cancer patients treated with capecitabine. Materials and Methods: The data of a total of 82 patients from three centers followed between June 2005 and June 2013 were retrospectively analyzed. The demographic data and hormone receptor status of the patients, as well as initial examination before and after treatment and data concerning progression were recorded. MCV ${\geq}100$ fl was considered as macrocytosis. Capecitabine was given at a dose of $2500mg/m^2$ daily for 14 days every three weeks. Pre-treatment and post-treatment MCV and other parameters of complete blood count were recorded. Post-treatment initial evaluation was performed after 2 cycles of therapy. Results: The median age of the patients was 46.5 years (range 26-72 years) and 54% were premenopausal. Performance status was ECOG 0 and 1 in 81 (99%) patients. The median number of cycles for capecitabine therapy was 5 (min-max: 2-18). The median ${\Delta}MCV$ level (post-treatment values at sixth week - baseline) was 6.4. Whilst ${\Delta}MCV$ was ${\geq}6.4$ in 42 patients, it was <6.4 in 40 patients. Clinical benefit (complete response+partial response+stable disease) was observed in 37 (88%) of 42 patients with a median ${\Delta}MCV$ ${\geq}6.4$ and in 30 (75%) of 40 patients with ${\Delta}MCV$ <6.4 with no statistically significant difference (p=0.158). No significant difference was determined between the group with ${\Delta}MCV$ ${\geq}6.4$ and the group with ${\Delta}MCV$ <6.4 in terms of progression-free survival (11 vs 12 months) (p=0.55) and overall survival (20 months vs. 24 months) (p=0.11). Conclusions: The identification of new predictive markers in metastatic breast cancer is very important. In some recent studies, increase in MCV has been suggested as a marker in tumor response. In the present study, however, no significant difference was determined between tumor response and increase in MCV. Further studies including higher numbers of patients are needed to determine whether increase in MCV is a predictive marker or not.

Hulusi Egilmez,Vedat Gok,Ibrahim Oztoprak,Mehmet Atalar,Ali Cetin,Mubeccel Arslan,Yener Gultekin,Orhan Solak 대한영상의학회 2007 Korean Journal of Radiology Vol.8 No.6

Objective: We wanted to compare the efficacies of 95% ethanol and 20% hypertonic saline (HS) sclerotherapies that were performed in a single session under CT guidance for the management of simple renal cysts. Materials and Methods: A prospective series of 74 consecutive patients (average age: 57.6 8.1 years) with simple renal cysts were enrolled in this study. They were randomized into two groups and 95% ethanol or 20% HS, respectively, corresponding to 25% of the aspiration volume, was injected. Treatment success was determined six months later with follow-up clinical evaluation and performing ultrasonography. Results: The sclerotherapy was accepted as technically successful without major complications in all except two patients who were excluded because of a communication between the simple renal cyst and the pelvicalyceal collecting system. Thirty-six patients in the ethanol group received sclerotherapy with 95% ethanol and 36 patients in the HS group underwent sclerotherapy with 20% HS. The complete regression ratio of the ethanol group was significantly higher (94% versus 72%, respectively) than that of the HS group. There was one patient with partial regression in each group. The failure ratio of the ethanol group was significantly lower (3% versus 25%, respectively) than that of the HS group. Conclusion: Ethanol sclerotherapy under CT guidance is a successful and safe procedure and it can be used for the treatment of simple renal cysts. Sclerotherapy with 95% ethanol is more effective than 20% HS sclerotherapy. Sclerotherapy with HS may be an option for patients preferring to undergo a less painful treatment procedure.

Ilhan, Tolgay Tuyan,Kebapcilar, Aysegul,Yilmaz, Setenay Arzu,Ilhan, Turkan,Kerimoglu, Ozlem Secilmis,Pekin, Aybuke Tazegul,Akyurek, Fikret,Unlu, Ali,Celik, Cetin Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.11

Background: The aims of this study were compare the serum visfatin and resistin levels between endometrial cancer (EC) patients and controls and evaluate their power to predict prognosis. Materials and Methods: This prospective study was conducted between March 2013 to June 2014 on the Gynecologic Oncology Department of the University of Selcuk, Konya, Turkey. A total of 42 EC patients and 42 controls were included and assessed for differences in serum visfatin and resistin levels, along with prognostic factors. Results: Endometrial cancer patients had significantly higher visfatin levels than control s (p: 0.011), associated with deep myometrial invasion (p: 0.019). In contrast the serum level of resistin did not significantly differ between EC patients and controls (p: 0.362). However, high resistin level in EC patients was associated with increase lymph node metastasis (p: 0.009). On logistic regression analysis, we found that serum visfatin elevation was associated with risk of myometrial invasion (OR: 1,091; 95%CI: 1.021-1.166; p: 0.010) and serum resistin with risk of lymph node metastasis (OR: 1.018; 95%CI: 1.000-1.035; p: 0.046). For myometrial invasion prediction, a serum visfatin level greater than 26.8 ng/mL demonstrated a sensitivity and specificity of 66.6 % and 96.4%, respectively. For lymph node metastasis prediction, the best cut-off for serum resistin level was 599ng/mL. A serum resistin level greater than this demonstrated a sensitivity and specificity of 87.5% and 77.1%, respectively. Conclusions: Our data suggest that serum visfatin is elevated in patients with EC and serum visfatin and resistin levels could be used to predict the risk of advance stage lesions.

Bulent Eser,Fevzi Altuntas,Isin Soyuer,Ozlem Er,Ozlem Canoz,Hasan Senol Coskun,Mustafa Cetin,Ali Unal 연세대학교의과대학 2006 Yonsei medical journal Vol.47 No.5

Brucellosis is a disease involving the lymphoproliferative system, which may lead to changes in the hematological parameters; however, pancytopenia is a rare finding. However, malignant diseases in association with brucellosis are rarely the cause of pancytopenia. Herein, two cases with fever and pancytopenia, diagnosed as simultaneous acute lymphoblastic leukemia and brucellosis are presented. Anti-leukemic therapy and brucellosis treatment were administered simultaneously, and normal blood parameters obtained. The first patient is in complete remission; the other recovered from the brucellosis, but later died due to a leukemic relapse.
