    OBJECTIVE Small cell lung cancer (SCLC) is the most aggressive type of lung cancer. Platinum-etoposide chemotherapy combination is used as first line treatment. The aim of this trial is evaluate the effect of complete response rates and clinical features in patients with extensive stage (ES) SCLC. METHODS In this retrospective study, a total of 117 patients from four different oncology centers in Turkey between 2011 and 2017 were divided into 2 groups, namely, patients with complete response (group 1) and those with no complete response (group 2) after platin-etoposide combination therapy. RESULTS The median age of the patients was 61 (range 38-81) years. The median follow-up time was 12 months and 95 (81\%) patients died. Progression-free survival (PFS) and overall survival (OS) were estimated, respectively, as 8 and 13 months. Overall survival of group 1 patients was statistically significantly better than the group 2 (16 versus 10 months respectively and p=0.00). The overall survival of patients who had late recurrent disease (>6 mo.) was statistically significantly better than the early ones (<6 mo) (19 versus 14 months respectively and p=0,008). CONCLUSION Complete response and recurrent free time were the prognostic factors for ES SCLC patients in our study

    Objective: In this study, we aimed to determine the correlation between pretreatment-staging 18F-FDG total body positron-emission tomography/computed tomography (PET/CT) maximum standardized uptake value (SUVmax) levels and histopathologic and immunohistochemical predictive and prognostic factors in patients with breast cancer. Materials and Methods: One hundred thirty-nine women with breast cancer who were treated between 2009 and 2015 at our hospital and who had pretreatment-staging PET/CT were included in the study. SUVmax levels and histopathologic and immunohistochemical results were compared. Results: The median age was 48 years (range, 29-79 years). The mean tumor diameter was 33.4 mm (range, 7-120 mm). The histology was invasive ductal carcinoma in 80.6\% of the patients. In the univariate analysis, SUVmax levels were significantly higher in patients with invasive ductal carcinoma
