Correlation of Tumor Infiltrating Lymphocytes and Tumor Staging in Rectal Carcinoma: A Study in a Tertiary Cancer Care Centre in North East India

Colorectal cancer is responsible for 10% of cancer cases and 9.4% of cancer-related deaths and it's one of the commonest cancers in north-east India. Recognition of the prognostic effect of tumor-inltrating lymphocytes and tumor-related immune responses has recently taken interest of the researcher and many of them are trying to nd a prognostic implication of the same. Many scorings system have been developed for this purpose. Here we are using the scores by International TILs Working Group (ITWG) and will try to nd the relation between tumor inltrating lymphocytes and tumor staging considering gender, age, size of tumor, histopathological ndings, grading, lymphovascular invasion, perineural invasion, depth of invasion, nodal status and metastastic potential. All ndings will be assessed for signicance using p value and nal correlation will be done using Pearson correlation index
