About Colorectal Cancer and Metastatic DiseaseWith nearly 140,000 new diagnoses and 50,000 deaths each year in the U.S., adenocarcinomas of the colon and rectum are a common and deadly form of cancer. When patients are first diagnosed with these diseases, they undergo surgeries to remove their tumors. Colon and rectal (colorectal) cancers, like nearly all forms of cancer, are insidious in that they can spread or metastasize from their primary sites of origin to multiple locations throughout the body. Patients who eventually succumb to colorectal cancer are killed by the uncontrolled growth of these metastatic tumors. It is well established that for colorectal cancers the most common site to which the cancer will spread first is the liver. Frequently, it is still possible to cure or dramatically extend the life of a patient with liver metastases using surgery if their cancer has not yet spread beyond the liver. About one third of colorectal cancer patients undergo surgeries to remove liver metastases. About Navidea Biopharmaceuticals, Inc. Navidea Biopharmaceuticals, Inc.
