    Background: Osteosarcomas are the most common solid malignancies of bone. In the last two decades there have been no concrete developments in their systemic treatment. In this trial we aimed to present our osteosarcoma patient clinical and demographic outcomes. Materials and Methods: Patients treated and followed up for osteosarcoma in Ankara Numune Education and Research Hospital from 2002 to 2012 were reviewed retrospectively. Results: A total of 21 patients (15 male, 6 female) were diagnosed with osteosarcoma. The disease was located at extremities in 76% and in 14% was metastatic at the time of diagnosis. Median disease free survival (DFS) was 36 months in non-metastatic patients and median progression free survival (PFS) was 2 months in metastatic patients (p<0.0001). Median overall survival (OS) was 80 months and 4 months, respectively (p=0.012). There were no survival differences in terms of presentation with pathological fracture, tumor size, tumor grade, alkaline phosphatase and lactate dehydrogenase level and type of chemotherapy regimen. Conclusions: Tumor site and stages are the most important prognostic factors for osteosarcoma. Extremity primary tumors have beter survival rates than non-extremity tumors. As a result of the use of effective chemotherapy the long term survival rates have improved from 10-20% to 60-70% in the last decades but we need more active agents, especially for metastatic cases.WoSScopu

    WOS: 000378564500006PubMed: 27155881Objective This study compares reducing radiation and operation time between single and double C-arm fluoroscopy in the treatment of intertrochanteric femur fractures with intramedullary nails. Patients and methods Forty four patients participated in the study. Patients were divided into two groups as single (23 patients) and double fluoroscope (21 patients). The time of preparation, the duration of the surgery, the total amount of blood loss, and the total duration of radiation exposure were compared, retrospectively. The collo-diaphyseal angle was compared with that of the contralateral hip on postoperative radiographs. Furthermore, the tip-apex distance and the position of the screws in the femoral head were recorded. Results The mean preparation periods, collo-diaphyseal angles and blood loss did not differ between groups. In the double-fluoroscopy group, the duration of surgery was 15.9 min shorter (p < 0.001), and the radiation time was 25.7 s shorter (p < 0.001). Conclusion The double fluoroscopy technique can significantly reduce surgical and radiation exposure times during surgery

    Background: Ewing sarcoma is a small round cell tumor arising from soft tissue and bone that predominantly affects children and adolescents. The most unfavorable prognostic factor is the presence of distant metastasis at the time of diagnosis. Materials and Methods: The records of 26 Ewing sarcoma patients (14 male, 12 female) were re-evaluated retrospectively. Results: The median age was 26.5 (19-42) years. Eight patients (31%) showed a primary tumor in their extremities, 8 (31%) in the thorax, 4 (15%) at the vertebra, 4 (15%) in the head and neck, and 2 (8%) in the abdomen. Five patients (19%) had distant metastasis at diagnosis. The median progression-free survival was 72 months and 10 months in localized and metastatic disease, respectively (p=0.005). The overall survival rate was 19 months in metastatic disease, and the 5-year overall survival rate was 64% in localized disease (p=0.006). Patients who had localized disease in the extremities and were under age 30 had a favorable prognosis. Conclusions: Although Ewing sarcoma is a tumor affecting children and adolescents, it may be seen in adults, where the prognosis is generally worse. Although it is a highly malignant tumor, it is possible to achieve improved survival with combined modality treatments.WoSScopu

    Could The Neutrophil To Lymphocyte Ratio Be A Poor Prognostic Factor For Non Small Cell Lung Cancers?

    Background: Although many prognostic factors have been identified for lung cancers, new ones are needed to determine the course of the disease. Recently, a high neutrophil to lymphocyte ratio (NLR) prior to surgery or treatment has been shown to be an indicator of prognosis for cancer. The aim of this study was to investigate the value of NLR as a prognostic factor and the correlation between NLR and other probable clinical prognostic factors in non small cell lung cancer patients prior to treatment. Materials and Methods: Data of patients who were diagnosed with non-small cell lung cancer in our institution were retrospectively reviewed. Demographic and clinicopathologic characteristics were recorded. NLR was calculated before the application of any treatment. Results: A total of 299 patients, 270 (90%) males and 29 (10%) females, were included in the study. Age (p= 3 (p=0.048), NLR >= 4 (p=0.025) and NLR >= 5 (p=0.018) were found to be the prognostic factors. Age, anemia, Eastern Cooperative Oncology Group performance status, the stage, NLR (>= 5) were an independent prognostic factors. There was a positive correlation between NLR and the Eastern Cooperative Oncology Group performance status (0.23, p=0.001), the C reactive protein levels (r=0.36, p<0.001). Conclusions: Prior to treatment high NLR was found as an independent poor prognosis factor. Besides, NLR correlated with Eastern Cooperative Oncology Group performance status and the C reactive protein levels.WoSScopu

    Lung Cancer in Women: A Single Institution Experience with 50 Patients

    Background: Lung cancer is the most common cause of cancer-related death worldwide. The incidence of lung cancer is aproximately 7-8 thousand percent in Turkish women. In this study, we aimed to evaluate the clinical, pathological properties and survival data of female patients with lung cancer who were treated in our center. Materials and Methods: From 2007 to 2012, 50 women with lung cancer were enrolled. Patient data were evaluated retrospectively. Results: The median age was 61 (40-81). Forty patients (80%) were diagnosed with non small cell lung cancer (NSCLC), 10 patients (20%) were small cell carcinoma (SCC). Twelve (24%) patients were smokers and 13 of 16 non-smokers had a history of exposure to asbestos. The most common histologic subtype was adenocarcinoma (46%) and this accounted for 71% in patients with exposure to asbestos. The most common initial Eastern Cooperative Oncology Group (ECOG) performance score was 1 (24 patients, 48%) and initial stage was IV (25 patients, 50%) in the study group. During the median 15 months (1-96 months) follow-up period: 1 year overall survival (OS) was 68%, 2-year overall survival was 36% and the median survival time was 19 months. According to univariate analysis, poor ECOG performance status, advanced stage, anemia and weight loss at time of diagnosis were negative prognostic factors. However, adenocarcinoma sub-type was a positive prognostic factor. Conclusions: In this study NSCLC sub-type, poor ECOG performance score, advanced stage, anemia and weight loss were prognostic factors in Turkish women with lung cancer.WoSScopu

    The aim of this study was to evaluate prognostic factors, survival rate and the efficacy of the treatment modalities used in patients with Ewing sarcoma family of tumors (ESFT). Data of patients with ESFTs followed up at different cancer centers in Turkey between 2001 and 2010 were retrospectively analyzed. The median age of 114 patients was 26 years (range 14-66). The median follow-up was 20 months (range 1-118 months). Tumor size was between 1.5 and 14 cm (median 8 cm). Eighty-six percent of patients had localized disease at presentation, and 14 % had metastatic disease. Local therapy was surgery alone in 31 % of patients, surgery combined with radiotherapy in 41 % and radiotherapy alone in 18 %. Approximately 70 % of patients were treated with vincristine, doxorubicin, cyclophosphamide and actinomycin-D, alternating with ifosfamide and etoposide every 3 weeks. In patients with localized disease at presentation, the 5-year disease-free survival and overall survival were 60 and 65 %, respectively. At univariate analysis, patients with tumor size >= 8 cm, high serum lactate dehydrogenase, metastasis at presentation, poor histological response to chemotherapy and positive surgical margin had significantly worse event-free survival. The significant predictors of worse overall survival at univariate analysis were tumor size <= 8 cm, high lactate dehydrogenase, metastasis at presentation, poor histological response to chemotherapy, radiotherapy only as local treatment and positive surgical margin. ESFTs are aggressive tumors with a high incidence of local recurrence and distant metastasis. Multimodality treatment consisting of adequate surgical resection, aggressive chemotherapy (VAC alternating with IE) and radiotherapy is recommended for patients with ESFTs
