ABSTRACT
In this study, we planned to investigate the clinical course of patients with breast cancer with oligometastatic bone disease (OMBD). The patients were grouped according to the characteristics and the sites of metastases. Group I included 928 patients without metastasis. Group II, the OMBD group, included 68 patients. Group III, the widespread metastasis group, comprised 185 patients with multiple bone metastases and/or solid organ metastases. The mean overall survival of the groups was 16.7 ± 0.3 years in group 1, and 7.8 ± 0.8 and 5.9 ± 0.4 years in groups 2 and 3, respectively (p < 0.001 for the comparison of all three groups together; p < 0.001 for group 1 vs. 2 and 3) and (p = 0.037 for group 2 vs. group 3). In the subgroup survival analysis of patients in group 2 (OMBD), the mean and median survival was 5.5 ± 0.8 and 4.0 ± 0.8 years vs. 9.2 ± 0.98 and 9.0 ± 1.05 years in patients with more than one bone metastasis and single bone metastasis, respectively (p = 0.019). OMBD seems to be a different disease than breast cancer with isolated bone metastases. The high risk of developing OMBD, especially following locoregional recurrence, increases the importance of locoregional therapy in large T and N stage tumors.

Background/aim: Ischemia on the colon wall negatively affects healing of anastomosis. We were aimed to evaluate the effects of carbon monoxide releasing molecule-2 (CORM-2) on the healing of anastomosis in a rat model of the ischemic colon. Materials and methods: In this prospective study a total of 60 rats were randomly divided into three groups as colon transection and end-to-end anastomosis (Group I), colon transection, and end-to-end anastomosis following the induction of ischemia (Group II), and colon transection and end-to-end anastomosis following the induction of ischemia and treated with daily intraperitoneal administration of CORM-2 (Group III). Each group was also divided into two equal subgroups as postoperative 3rd and 7th day. Postoperative healing of anastomoses was evaluated by anastomosis burst pressure (ABP), tissue biomarkers including hydroxyproline (HP), malondialdehyde (MDA), glutathione (GSH), and histopathological findings. Results: In the ischemic group treated with CORM-2, lower MDA and higher HP levels were observed in comparison to the untreated ischemic group on the 3rd day. GSH and HP levels were higher and MDA levels was lower in the ischemic rats treated with CORM-2 than in the ischemic untreated rats on the 7th day. In the ischemic group treated with CORM-2, the mucosal epithelial score decreased and the neoangiogenesis score increased compared to the untreated rats on the 7th day. Conclusion: In ischemic colon anastomosis, reduces cell destruction by suppressing the oxidative reaction, and strengthening the antioxidative mechanisms of the cells. It also increases collagen formation, epithelial development, and neoangiogenesis.

⺠GISTs do not have a unique appearance on ultrasound examination. ⺠If a pelvic mass is detected, the possibility of a non-gynecological tumor like GISTs has to be considered.
ABSTRACT
OBJECTIVES: The objective this study is to evaluate the trend of Turkey's contribution in terms of number of publications included in the Science Citation Index Expanded in kidney transplantation between 1980 and 2009. MATERIALS AND METHODS: All scientific papers published included in Science Citation Index Expanded in the English language between 1980 and 2009 were analyzed using the "Web of Science." A general search was conducted using key words of "kidney transplantation," "renal transplantation," "kidney transplant," and "renal transplant." We analyzed these results using the "analyze" function of the software in terms of countries, documentation types, number in years of publications, journals, and institutes. We also used the same function separately analyze papers from Turkey in last 3 decades between 1980 and 1989, 1990 and 1999, and 2000 and 2009 for statistical evaluation. RESULTS: In total, we found 46 983 papers related to kidney transplant were published included in the Science Citation Index Expanded in the English language between 1980 and 2009. Overall, 964 of those papers were from Turkey (2.05%). There were 12 papers from Turkey between 1980 and 1989, 200 papers between 1990 and 1999, and 752 papers between 2000 and 2009. The rank of Turkey among other countries, ranked by the number of papers published, was 33 between 1980 and 1989 and 11 between 2000 and 2009. CONCLUSIONS: Turkey has shown a significant positive trend in publishing papers in the field of kidney transplantation-further evidence of the progress Turkey has made in its contributions to the field of kidney transplantation in recent decades.
