Immunomarkers for Detection of GI Malignancies

Gastrointestinal (GI) cancers are related to several diseases of the GI tract including adenocarcinomas of the esophagus, stomach, colon, and rectum, which are among the leading cause of morality worldwide. In spite of rapid development in molecular and genomic techniques, prognosis of the malignant potential of GI cancers is challenging. Immunomarkers may play an important role in the prediction of malignant behavior of these cancers. In this chapter, we have made an attempt to provide a comprehensive review on immunomarkers which are discovered recently and used in the detection of GI malignancies. These immunomarkers can help clinicians in the early diagnosis and as therapeutic targets to treat GI cancers.
