AIM:To investigate the prognostic value of preoperative platelet count(PLT) in patients with primary gallbladder cancer(GBC).METHODS:The clinical data of 223 GBC patients after surgery was retrospectively reviewed.A receiver operating characteristic(ROC) curve was plotted to verify the optimum cutoff point for PLT.Univariate and multivariate survival analyses were performed to identify the factors associated with the prognosis.RESULTS:The ROC curve showed that the optimum cutoff point for PLT was 178 × 109/L,and the entire cohort was stratified into group A with PLT 178 × 109/L and group B with PLT ≤ 178 × 109/L.Group A had a better survival than group B(P 0.001).There was an obvious difference between the two groups in terms of the differentiation degree,advanced tumor stage,lymph node metastasis(P 0.001) and pathological type(P 0.05).The univariate analysis demonstrated that tumor location,differentiation degree,TNM stage,Nevin stage,lymph node metastasis and PLT were associated with overall survival(P 0.001).In the multivariate analysis,PLT(P = 0.032),lymph node metastasis(P = 0.007),tumor location(P 0.001) and TNM stage(P = 0.005) were independent prognostic factors.CONCLUSION:PLT is closely correlated with GBC prognosis and could be used to identify the population with a poorer prognosis after surgery. 相似文献

Stage I non-small cell lung cancer (NSCLC) show a highly variable biological behavior which cannot be accurately predicted by the current available prognostic markers. Platelet plays a significant role in cancer cell growth, progression and metastasis. This study aimed to investigate whether preoperative platelet count correlate with clinical prognosis in localized NSCLC. A retrospective clinical analysis was designed for a total of 234 stage I NSCLC patients in our hospital between October 2006 and December 2009. Pre-operative platelet count was measured. The association of platelet count with clinical pathological factors and patient outcome was evaluated. A significant correlation was detected between platelet count and tumor cell differentiation and T stage. Patients with elevated platelet count had an elevated risk of disease progression and death compared to patients with normal platelet count. The hazard ratio was 5.314 (95% confidence interval [CI] 2.750–10.269) for disease progression and 3.139 (95% CI 1.227–8.034) for death. The trend linking increasing platelet count with risk was also statistically significant for both the outcomes (p?<?0.05). These finding demonstrate that preoperative platelet count is a useful predictor of high risk progression and poor prognosis in stage I NSCLC patients. 相似文献

This study investigated alterations in platelet counts pre- and post-treatment with artemisinin derivatives in uncomplicated and severe falciparum malaria. Serial platelet counts were taken over 4 weeks for 110 uncomplicated and 110 severe falciparum malaria patients admitted to the Hospital for Tropical Diseases during 2005-2008. On admission, prior to treatment, thrombocytopenia was found in 73.6% of uncomplicated falciparum malaria patients and 90.9% of severe falciparum malaria cases. Platelet levels significantly lower in severe malaria cases. Although initial platelet counts were lower than normal in both study groups, they slowly increased significantly over time, and approached normal levels by several weeks post-treatment. No bleeding was evident during treatment, and none of the patients required a platelet transfusion. Platelet transfusions are not required for malaria patients with thrombocytopenia who have no bleeding. 相似文献
