Background: To determine prognostic value of excision repair cross-complementation 1 (ERCC1) in patients with malignant pleural mesothelioma (MPM). Materials and Methods: The study included 60 patients with MPM who were diagnosed and treated in the Radiation Oncology Department of Kayseri Teaching Hospital and Medical Oncology Department of Erciyes University, Medicine School between 2005 and 2013. By using immunohistochemical methods, ERCC1 expression in biopsy specimens was evaluated. We retrospectively assessed whether there is a correlation between ERCC1 and response to anti-neoplastic therapy or survival. Results: There were 50 men and 10 women with median age of 62 years (range: 39-83). Histological type was epithelial mesothelioma in the majority of the cases (85%), most commonly presenting in stage four. Of the cases, 20 (33%) received radiotherapy, 60 (%100) received first-line chemotherapy and 15 (%25) received second-line chemotherapy. In the assessment after therapy, it was found that there was partial response in 12 cases (20%), stable disease in 19 cases (31.4%) and progression in 25 cases (41.7%). ERCC1 was positive in 43% of the cases. Mean OS was 11.7 months and mean DFS was 9.5 months in ERCC1-positive cases regardless of therapy, while they were 19.2 months and 17.1 months in ERCC1-negative cases, respectively. The difference was found to be significant (p<0.05). In univariate analysis, stage, comorbidity, response to treatment and ERCC1 expression were found to be significantly associated with OS (p=0.083; p=0.043; p=0.041; p=0.050). In multivariate analysis, response to treatment remained to be significant for OS (p=0.005). In univariate and multivariate analyses, response to treatment and ERCC1 were found to be significantly associated with DFS (p=0.049; p=0.041). Conclusions: ERCC1 was identified as poor prognostic factor in patients with MPM.

Background: It has been demonstrated that neutrophil:lymphocyte (NLR) and platelet:lymphocyte (PLR) ratios are associated with prognosis in cancer patients. The aim of this study was to investigate whether pretreatment white blood cell (WBC), neutrophil, lymphocyte, monocyte, platelet, basophil and eosinophil counts, LDH level, NLR and PLR are associated with prognosis in patients with malignant pleural mesothelioma (MPM). Materials and Methods: We retrospectively reviewed files of 50 patients who were managed with a diagnosis of MPM between 2005 and 2010. Demographic and clinical characteristics, treatments, response to treatment and prognostic factors were evaluated, along with relationships between pretreatment blood parameters and prognosis. Results: Overall, 38 men and 12 women were included to the study. Mean age was $61.5{\pm}9.4$ years (range: 39-83 years). There was advanced disease in 86% (n=43) and the histological type was epithelial mesothelioma in the majority (82%). Of the cases, 17 (34%) received radiotherapy, while 42 cases underwent first- and second-line chemotherapy, with cisplatin plus pemetrexed as the most commonly used regimen. In the assessment after therapy, it was found that there was complete response in 4 cases (8%), partial response in 10 cases (20%), stable disease in 17 cases (34%) and progression in 19 cases (38%). Median follow-up was 10 months (range: 10 day-30 months). Median overall survival was found to be 20.7 months while median progression-free survival as 10 months. In univariate and multivariate analyses, it was found that factors significantly affecting overall survival included stage (p=0.030), response to treatment (p=0.026) and monocyte count (p=0.004), while factors affecting disease-free survival included NLR (p=0.018), response to treatment (p=0.001), and PLR score (p=0.003). Conclusions: Overall and disease-free survival was found to be better in cases with a WBC count<8.000, platelet count<300,000, and low NLR and PLR scores in malignant pleural mesothelioma.

In patients with Kawasaki disease (KD), evolution of coronary artery aneurysms (CAAs) generally emerges within the first few weeks after disease onset. However, CAA formation in these patients might occasionally arise as a late-onset phenomenon after a long latent period. Characteristically, late CAAs manifest as new-onset vascular pathologies or expansion of long-stable CAAs on coronary imaging modalities, and might have diverse mechanistic and clinical implications. Accordingly, the present paper aims to focus on late CAA formation and its implications in the setting of KD.
