    COMPARISON OF SKIP EXPRESSION IN MALIGNANT PLEURAL MESOTHELIOMAS WITH KI-67 PROLIFERATION INDEX AND PROGNOSTIC PARAMETERS
    (Vesalius Univ Medical Publ, 2016) Turkcu, Gul; Alabalik, Ulas; Keles, Ayse Nur; Ibiloglu, Ibrahim; Kucukoner, Mehmet; Sen, Hatice Selimoglu; Buyukbayram, Huseyin
    We aimed to determine the presence of SKI-interacting protein (SKIP) expression in malignant pleural mesothelioma (MPM) and its effect on prognosis by investigating SKIP correlation with the Ki-67 proliferation index and prognostic parameters. Pathological preparations of the patients diagnosed with MPM between 2006 and 2012 were evaluated. Immunohistochemical analyses were performed to evaluate the expression of SKIP and the Ki-67 proliferation index. Correlations between SKIP expression, clinicopathological factors and survival were investigated. Survival data were calculated using the Kaplan-Meier method, and Cox regression analysis was used to evaluate the prognostic value of the variables. In total, 52 patients were evaluated in the study; 36 of them were male and 16 were female. The mean age of the patients was 62.3 +/- 12.2 years. The median overall survival period was 8.5 months. Factors negatively affecting general survival in the univariate analysis included high SKIP expression, Ki-67 proliferative index over 30%, presence of non-epithelioid type MPM and stage III-IV disease (p < 0.05). Cox regression analysis revealed that high SKIP expression, high Ki-67 proliferative index and presence of non-epithelioid type MPM are independent factors that affect the survival rate. Higher SKIP expression is associated with poor prognosis in MPM.

    Prognostic factors in non-small cell lung cancer patients and prognostic importance of PET/CT SUV max value
    (Turkish Assoc Tuberculosis & Thorax, 2012) Erdem, Vedat; Sen, Hatice Selimoglu; Komek, Halil; Tanrikulu, A. Cetin; Abakay, Abdurrahman; Sezgi, Cengizhan; Kaya, Halide
    Introduction: This study planned to investigate the maximum standard uptake values (SUV max) at fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT) whether associated with survival or not and the effect of demographic, clinical and laboratory data on survival in non-small cell lung cancer (NSCLC) patients. Materials and Methods: This study was created by examining retrospectively the records of 101 patients with NSCLC that received a definitive diagnosis and FDG-PET/CT used for staging in our center between May 2006-March 2011. Especially FDG-PET/CT, SUV max and the other clinical, histopathologic, laboratory and treatment parameters that effects prognosis were recorded and statistical analysis was performed. Results: Eighty eight (87.1%) of the patients were men and 13 (12.9%) were women. The average survival period was 10.6 +/- 8.5 (1-49 months) months. The demographic, clinical, laboratory and radiological parameters were divided into two groups with the median value of SUV max (12.0). There was not a significant difference in survival between the two groups (p= 0.807). The study showed that advanced stage, presence of metastasis, high lactate dehydrogenase (LDH) levels, high white blood cell levels, inoperability, low albumin levels and low performance effect negative on survival. Conclusion: It was considered that SUV max does not play an important role in the survival period of NSCLC patients. Knowledge of performance condition, serum LDH, leukocyte and albumin values may provide a better prognostic evaluation.

    Pulmonary Langerhans' Cell Histiocytosis and Diabetes Insipidus: On the occasion of two cases
    (Aves, 2012) Sezgi, Cengizhan; Abakay, Abdurrahman; Tanrikulu, Cetin; Sen, Hatice Selimoglu; Senyigit, Abdurrahman
    Pulmonary Langerhans' cell histiocytosis (PLCH) is an uncommon interstitial lung disease with an unknown etiology in smokers. Disease is usually seen with isolated lung involvement and central nervous system involvement is rare. Two PLCH cases, with central diabetes insipidus (DI) determined at diagnosis in one of the cases and during follow-up in the other, is being presented in this report. The patients' ages were 39 and 24, respectively and they were both male patients with a history of smoking. Widely cystic lesions were viewed at high-resolution computed tomography scans (HRCT) and PLCH was detected at the biopsies obtained by video-assisted thoracoscopic surgery (VATS), in both two cases. Therapy was started with 0.5 mg/kg methyl prednisolone for latter case, because of impairment in pulmonary function tests during follow up. On control, after one month therapy, partial improvement was seen for PLCH and the therapy was continued up to 6 months. At the end of the therapy complete remission was seen and corticotherapy was stopped. Desmopressin was started for both cases at 0.1 mg/day, orally. After one month of treatment clinical improvement was observed during control.
