ABSTRACT
@#[Abstract] Objective: To explore the relationship between the preoperative blood indicators (platelets, monocytes, neutrophils-to-lymphocyte ratio) and clinicopathological characters and the prognosis of the early stage malignant melanoma（MM）patients. Methods: Clinicopathological data of 120 cases of stage I-III MM patients, who received initial treatment and radical operation in the Cancer Hospital of Tianjin Medical University from January 2007 to May 2012, were obtained for this study. The correlations between parameters of PLR (platelet-to-lymphocyte ratio), LMR (lymphocyte-to-monocyte ratio), NLR (neutrophil-to-lymphocyte ratio), hemoglobin, neutrophils, lymphocytes, monocytes, eosinophils, basophils, platelets, lactate dehydrogenase, age, stage as well as ulcer and the prognosis of the patients were evaluated. Results: Patients whose tumor with ulceration have higher NLR and basophilic granulocyte (all P< 0.05）. Univariate analysis showed that NLR, PLR, LMR, neutrophil, lymphocyte, monocyte, lactic dehydrogenase, age, stage and ulceration were the risk factors of poor 5-year overall survival (P<0.05). The multivariate analysis identified PLR（HR=4.206， 95%CI:1.65410.696， P<0.01），stage（HR=7.670， 95%CI:3.977-14.795， P<0.01）and ulceration（HR=1.931， 95%CI:1.029-3.623， P<0.05）as independent risk factors for the prognosis of the MM patients. Conclusion: Higher preoperative PLR can be used as a predictive factor for poor prognosis of the early stage MM patients.
ABSTRACT
@# Objective: To explore the relationship between monocyte-to-lymphocyte ratio (MLR) in peripheral blood of patients with pulmonary sarcomatoid carcinoma (PSC) and their clinicopathological features and prognosis, and to investigate its clinical significance. Methods: A retrospective analysis was carried out to analyze the complete case data of 80 patients with PSC from October 2010 to April 2017 in Tianjin Cancer Hospital (monocyte and lymphocyte counts of peripheral blood, clinicopathological features, and survival follow-up). The receiver operating curve (ROC) was used to determine the best cut-off value of MLR for the prediction of overall survival time (OS). The patients were divided into high MLR group and low MLR group. Kaplan-Meier method was used to calculate OS and draw survival curves. The Log-Rank test was used to compare the difference in OS between the two groups. The variables with statistical significance in univariate analysis were included into the COX risk regression model to verify and calculate thehazard ratio (HR)and 95% confidence interval (95%CI). Results: The absolute median values of monocytes and lymphocytes were 0.63×109/L and 1.84×109/L, respectively. The best cut-off value of MLR is 0.44. Univariate analysis shows that MLR≥0.44 (P<0.01), no radical surgery (P<0.01), clinical stage Ⅲ+Ⅳ (P<0.01), tumor maximal diameter > 3 cm (P<0.01), and LDH>247 U /L (P<0.01) are the poor prognostic factors affecting overall survival. Multivariate analysis shows that MLR≥0.44（HR=3.554; 95%CI=1.671-6.125; P<0.01), and clinical stage Ⅲ+Ⅳ（HR=3.275; 95%CI=2.047-9.399; P<0.01) are the independent risk factors for the overall survival of PSC, and radical surgery is an independent protective factor affecting the overall survival of PSC（HR=0.360; 95%CI=0.195-0.848; P<0.01). Conclusion: High MLR is an independent risk factor for poor prognosis in patients with PSC.
