4 统计学分析按照肿瘤类型进行分类，每类肿瘤中各临床及病理参数以Lni

4 Statistical analysis <br>is classified according to the type of tumor. Each clinical and pathological parameter in each type of tumor will be divided into three groups of A, B and C with the Lni50% and 75% digits as the cut-off value, and the lymph node index will be compared with other clinical use currently. Correlation of pathological parameters and TNM stages and differences between groups; and Spearman correlation test and multiple linear regression analysis were performed on them, and P <0.05 was used as the standard to judge whether there was significance.

4 statistical analysis<br>According to the classification of tumor types, the clinical and pathological parameters of each type of tumor were divided into three groups, i.e. a, B and C, with the 50% and 75% digits of lnI as the boundary values. The correlation and difference between the lymph node index and other clinical and pathological parameters currently used and TNM stage were compared. The significance of the tumor was judged by Spearman correlation test and multiple linear regression analysis, with P < 0.05 as the standard 。<br>
