RESUMO
It is very well known that the tumor-host interaction is not limited to the tumor microenvironment but to also alter the entire physiological process to help the development and progression of cancer. Our immune system does not escape from the clutches of the cancer, i.e altered hematological parameters can influence the progression of cancer and vice versa. With this in mind we conducted this study in the Department of Pathology MMC&RI with an attempt to reveal the pattern of complete blood count in malignancies and their difference in localized and metastatic cancer. All the cases included in this study were the ones referred to Cytopatholgy, and diagnosed with cancer. There was significant statistical correlation between the various hematological parameters and the metastatic cancers implying their use to predict the tumor behavior
