Background: Breast cancer is the most common malignancy and the second leading cause of cancer-related death among women in the developed countries. Despite advances in screening, improved local therapies and adjuvant systemic treatments, median survival of metastatic breast cancer patients (MBC) is in the range of 2-3 years at most. We aimed to investigate whether the prognostic factors and therapeutic responses of our Turkish patients are similar to those in the literature. Materials and Methods: We reviewed the medical records of MBC patients who had been treated in our institution between 1999-2009 and analyzed their clinicopathological features and survival outcomes retrospectively Results: A hundred and sixty patients were included. Median age was 47 (23-82), median follow up was 24 (2-186) months. At the time of diagnosis 59% of patients were under the age of 50 and 46% were postmenopausal. The majority (37%) had multiple sites of metastases. Forty percent received endocrine therapy and 40% chemotherapy as first line metastatic treatment. Thirty (20%) patients were treated with molecular targeting agents like trastuzumab, lapatinib and sunitinib, frequently combined with a chemotherapy agent. Five-year overall survival (OS) was 32% and median OS was 38 months for the whole group. Five year progression free survival (PFS) was 10% and median PFS was 10 months. Menopausal status, hormone receptor expression and disease free status had a significant impact on overall survival in the multivariate analysis (p 0.018, p 0.018 and p:0.003, respectively). Conclusions: All our patients were treated with the modern oncologic therapies recommended by the international guidelines. From our data, MBC patients live up to 3-4 years, indicating that further improvement beyond that requires development of new treatment modalities. The survival outcomes of our patients were consistent with the data reported in the literature.
Background: This study aimed to research the awareness of screening colonoscopy (SC) among patients with colorectal cancer (CRC) and their relatives. Methodology: A questionnaire form including information and behavior about colonoscopic screening for CRCs of patients and their first-degree relatives (FDRs) was prepared. Results: A total of 406 CRC patients were enrolled into the study, with 1534 FDRs (siblings n: 1381 and parents n: 153). Positive family history for CRC was found in 12% of the study population. Previous SC was performed in 11% of patients with CRC. Mean age of the patients whose FDRs underwent SC was lower than the patients whose FDRs did not (52 vs 57 years; p<0,001). The frequency of SC in FDRs was 64% in patients diagnosed CRC under 35 years of age. Persons having a positive family history of CRC had SC more often (51 vs 22%, p<0,001). FDRs of patients having a higher educational level and income had SC more frequently. Conclusions: When screening for CRC is planned, elderly subjects, those with family history for CRC, and those with low educational and lower income should be given esspecial attention in order that they be convinced to undergo screening for CRC.
Purpose: This study assessed the associations between chronological age, dental maturation (DM), cervical vertebrae maturation (CVM), and hand-wrist maturation (HWM) in individuals aged 9-19 years. In addition, this study aimed to derive practical methods to evaluate the skeletal age using DM, CVM, or HWM for orthodontic, medical, and forensic purposes and to compare which of these 3 developmental parameters is more accurate for estimating the age of individuals in a Turkish population. Materials and Methods: Panoramic, lateral cephalometric, and hand-wrist radiographs of 284 patients aged 9-19 years were used in this study. The DM, CVM, and HWM stages were determined. The Kolmogorov-Smirnov, kappa, Wilcoxon, Kruskal-Wallis, chi-square, and Spearman correlation tests and simple linear regression analysis were used for statistical analysis. The significance level was 0.05. Results: Statistically significant differences were found between chronological age and DM, chronological age and CVM, and chronological age and HWM in both sexes (P<0.05). DM did not show statistically significant differences according to sex (P>0.05), but CVM and HWM were statistically different between males and females (P<0.05). The DM-estimated age yielded more accurate values than the other methods. Conclusion: All correlations between skeletal and dental stages were statistically significant. Our results showed that there was no statistically significant difference between chronological age and DM-estimated age. Therefore, it can be concluded that DM stages have the potential to be used for legal purposes.

Background: To evaluate the clinicopathologic and demographic characteristics of triple-negative breast cancer (TNBC) patients and to determine differences from non-triple-negative cases. Materials and Methods: A detailed review of the medical records of 882 breast cancer (BC) patients was conducted to obtain information regarding age, menopausal status, height and weight at the time of diagnosis, presence of diabetes or hypertension, and pathologic characteristics of the tumor (tumor size, lymph node status, histologic grade, ER status, PR status, HER2 status, p53 mutation). Body mass index (BMI) was calculated and a value of ${\geq}30$ was considered as indicative of obesity. Results: 14.9% (n=132) of the patients had TNBC. There was no difference among the patients in terms of median age, comorbid conditions and menopausal status. The proportion of medullary, tubular and mucinous carcinomas was significantly higher (15.9%) in the triple-negative (TN) group, while invasive lobular histology was more frequent (8.2%) among non-triple negative (NTN) cases (p<0.001). Grade 3 (G3) tumors were more frequent in the triple-negative group (p<0.001). The rate of p53 mutation was 44.3% in TN tumors versus 28.2% in the NTN group (p<0.001). The two groups were similar in terms of LN metastasis. In the NTN group, the rate of patients with BMI ${\geq}30$ was 53% among postmenopausal patients, while it was 36% among premenopausal women, and the difference was statistically significant (p<0.001). No significant difference was observed in terms of BMI between postmenopausal and premenopausal patients in the TN group (p=0.08). Conclusions: TNBC rates and clinicopathologic characteristics of the Turkish patient population were consistent with the data from Europe and America. However, no relationship between obesity and TNBC was observed in our study. The association between TNBC and obesity needs to be evaluated in a larger patient population.

Background: Retrospective data on 165 patients who presented with a parotid mass and underwent surgery in our clinics during 2000-2009 were examined. The obtained data (demographic data, surgical procedures, histopathological diagnoses) were compared to similar studies to make contributions to the literature. Materials and Methods: Patients were classified according to their histopathological diagnosis. Surgical procedures and patient follow-up were clarified. The results are presented as means and standard deviations. Results: Of the 165 masses, 134 (81.3%) were benign and 31 (18.7%) were malignant. Pleomorphic adenoma was the most common benign tumour (79 patients, 59%). Lymphoma and adenoid cystic carcinoma were equally common and were the most common malignant parotid gland tumours (both 6 patients, 19.3%). The most frequent surgical procedure was superficial parotidectomy (92 patients, 55.7%), and the most commonly encountered surgical complication was facial paralysis (12 patients, 7.2%). Conclusions: Our data are generally in line with the literature but lymphoma was more common than in most previous reports. Although the number of cases was low, the high incidence of parotid gland lymphoma was remarkable.
Objective: PCOS is one of the most common endocrine disorder affecting reproductive age women. It shows wide range of reproductive and metabolic manifestations. This study was to determine the differences of clinical and laboratory characteristics between adolescent and adult Korean Daegu Kyungpook PCOS patients. We also compared clinical and laboratory values of Korean PCOS patients to Turkish and American PCOS patients. Methods: 88 cases were diagnosed and enrolled as PCOS patients, based on 2003 Rotterdam criteria, who visited KNUH Reproductive Endocrinology division between Jan. 2000 and Apr. 2008. We retrospectively reviewed clinical characteristics, serum hormone levels, ultrasono-graphic findings. And we divided into 2 groups, adolescent and adult. We analyzed them with Chi-square test and Student's t-test statistically. Results: There were no statistically significant differences between adult and adolescent Korean PCOS patients. The prevalence of hyperandrogenism such as facial acne or hirsutism, obesity, and insulin resistance of Korean PCOS women was significantly lower than Turkish and American PCOS women. Conclusion: From the results of this study, we can suggest that it is sure that there are differences of clinical and laboratory characteristics of PCOS patients between races. Genetic background, dietary habits and life style affect the expression of clinical symptoms of PCOS. But we could not find out the difference between adolescent and adult PCOS patients of same race. It might be due to the limitation of small patient number and narrow range of age distribution. So, there must be large scale and multi-center and multi-regional study.
Background: The aim of the present study was to evaluate the serum neuron-specific enolase (NSE) levels in patients with prostate cancer, Hodgkin lymphoma, lung cancer and peripheral nerve tumors. Materials and Methods: NSE levels were determined by ELISA in the sera of 100 prostate cancer, 47 Hodgkin lymphoma, 35 lung cancer and 35 peripheral nerve tumor patients and also in 132 healthy controls. Results: The median levels of serum NSE were elevated in patients with lung cancer (p=0.018) and peripheral nerve tumors (p=0.008). NSE levels in prostate cancer and Hodgkin lymphoma patients were higher than the controls but there was no statistically significant difference (p>0.05). Conclusions: We conclude that NSE may be applied in routine to gain insight about the clinical statuses of various cancer patients, but more studies are needed to determine the organ specificity.
Background: This study was planned in an attempt to develop scales for the assessment of fatigue in pediatric oncology patients aged 13-18 and also for their parents. Materials and Methods: In collecting the study data, we used the Child and Parent Information Form, Visual Fatigue Scale, Scale for the Assessment of Fatigue in Pediatric Oncology Patients Aged 13-18 and the Scale for the Assessment of Fatigue in Pediatric Oncology Patients Aged 13-18 for Parents. We also used Pearson correlation analysis, Cronbach alpha coefficient, factor analysis and ROC analysis for the study data. Results: In this study, the total Cronbach alpha value of the parent form was 0.99, the total factor load was 0.72-0.94 with 95% the total variance being explained. The cutoff point of the parent form is 73 points. The total Cronbach alpha value of the child form was 0.99, the total factor load was 0.82-0.95, with 89.4% of the total variance being explained. The cutoff point of the child form was 75.5 points. Conclusions: This study suggests that the Scale for the Assessment of Fatigue in Pediatric Oncology Patients Aged 13-18 and the Scale for the Assessment of Fatigue in Pediatric Oncology Patients Aged 13-18 for Parents are valid and reliable instruments in assessing the fatigue symptoms of children in Turkey.
Purpose: The aim of this study was to investigate the differences in quality of life in patients who received breast conserving surgery (BCS) or modified radical mastectomy (MRM) for breast cancer. Materials and Methods: A total of 100 women with breast cancer who underwent either BCS or MRM between September 2011 and April 2012 at a private health center and completed their chemotherapy and radiation therapy cycles were included in the study. To assess the quality of life, we used a demographic questionnaire, the European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) and the Quality of Life assessment in Breast Cancer (EORTC QLQ-BR23). Results: Using QLQ-C30, we found that patients who underwent BCS had better functional status and fewer symptoms than patients who underwent MRM. In QLQ-BR23, independent factors improving the functional scales were BCS, higher level of education and marital status (married); independent factors improving symptoms were BCS, higher level of education, younger age and low and normal body mass index (BMI). In QLQ-C30, independent factors affecting the functional and symptom scales were only BCS and higher level of education. Conclusions: We determined that patients who received BCS had better functional status and less frequent symptoms than patients who underwent MRM.

Although alteration in the haptoglobin phenotype has been reported in patients with bladder cancer, serum haptoglobin levels have not been evaluated. We hypothesized that serum haptoglobin can be used as a biomarker. The aim of this study was to evaluate the expression of haptoglobin in bladder cancer and to determine the relationship with clinicopathological features. A total of 68 serum specimens obtained before surgery were used to investigate haptoglobin expression using the sandwich ELISA technique. Serum haptoglobin levels were higher in the patients with bladder cancer compared to healthy controls (p<0.0001). Additionally, the levels of haptoglobin protein increased with increasing tumor grades (p<0.001) and were significantly higher in patients with metastatic disease and the presence of lymphovascular involvement, lymph node metastases and increasing tumor burden (p<0.0001). This study suggests that elevated haptoglobin levels are associated with a higher stage, grade, and extent of distant metastasis and larger tumor size. Haptoglobin may therefore provide a useful diagnostic and treatment biomarker for patients with bladder cancer.
