RESUMO
BACKGROUND: Most of the studies on salivary gland cancers are limited for various reasons such as being single-center, small number of patients, including only major or minor SGCs, or only including epidemiological data. METHODS: A total of 37 medical oncology clinics from different regions of Turkey participated in this retrospective-multicenter study. The analyzed data included clinical and demographical features, primary treatment, metastasis localizations, and treatments and includes certain pathologic features. RESULTS: The study included data from a total of 443 SGCs. 56.7% was in major salivary glands and 43.3% was in minor salivary glands. Distant metastasis in the major SGCs was statistically significantly more common than in the minor SGCs, locoregional recurrence was statistically significantly more common in the minor SGCs than in the major SGCs (p = 0.003). CONCLUSIONS: Epidemiological information, metastasis and recurrence patterns, treatment modalities, and survival analysis of the patients over 20 years of follow-up are presented.

BACKGROUND: We have aimed at exposing left ventricular diastolic functions and the presence of known genetic mutations for familial erythrocytosis, in patients who exhibit idiopathic erythrocytosis. METHODS: Sixty-four patients with idiopathic erythrocytosis (mean age, 46.4 ± 2.7 years) and 30 age-matched healthy subjects were prospectively evaluated. The regions of interest of the erythropoietin receptor, hemoglobin beta-globin, von Hippel-Lindau, hypoxia-inducible factor 2 alpha, and Egl-9 family hypoxia-inducible factor genes were amplified by PCR. Left ventricular (LV) mass was measured by M-mode and 2-dimensional echocardiography. LV diastolic functions were assessed by conventional echocardiography and tissue Doppler imaging. RESULTS: As a result of genetic analyses, genetic mutations for familial erythrocytosis were detected in 5 patients. It has been observed in our study that the risk of cardiovascular disorders is higher in patients. Interventricular septum thickness, left atrial diameter, and some diastolic function parameters such as deceleration time and isovolumetric relaxation time have been found to be significantly higher in idiopathic erythrocytosis group than in the controls. CONCLUSION: This study has shown that LV diastolic functions were impaired in patients with idiopathic erythrocytosis. In this patient group with increased risk of cardiovascular disorders, the frequent genetic mutations have been detected in 5 patients only. Therefore, further clinical investigations are needed as novel genetic mutations may be discovered in patients with idiopathic erythrocytosis because of cardiovascular risk.

BACKGROUND: Chronic state of inflammation is an important factor in advanced cancer which is used by tumor cells for maintaining survival and growth. Hematological parameters such as neutrophil/lymphocyte ratio (NLR), thrombocyte/lymphocyte ratio (TLR), and lymphocyte/monocyte ratio (LMR) are reliable indicators of systemic inflammation. We aimed to elucidate the effect of hematological parameters and clinical features of patients on the prognosis of advanced-stage non-small cell lung cancer (NSCLC). METHODS: We included 102 Stage IV NSCLC patients who presented to the oncology clinic between 2010 and 2016. Pretreatment clinical parameters and NLR, TLR, and LMR were retrieved from the medical records. The cutoff values, calculated with receiver operating curve analysis, for NLR, LMR, and TLR were 2.5, 3, and 183, respectively. All patients were divided into two groups according to cutoff values and analyzed accordingly. RESULTS: Median overall survival and progression-free survival were 10 and 6 months, respectively. In univariate analysis, high NLR, high TLR, and low LMR were found to be significantly associated with survival. Among clinical parameters having eastern cooperative oncology group performance score 0-1, older age (≥70 years) single metastatic disease was prognostic. In multivariate Cox regression analysis, only the number of metastatic lesions and LMR were found to be independent predictors for survival. CONCLUSION: Among hematological parameters, only LMR was found to be an independent predictor of survival in patients with advanced-stage NSCLC.
