stage III esophageal adenocarcinoma

Stage III is divided into stages IIIA, IIIB, and IIIC, depending on where the cancer has spread. In stage IIIA, cancer (1) is in the mucosa or submucosa layer and may have spread into the muscle layer of the esophagus wall, and cancer is found in 3 to 6 lymph nodes near the tumor; or (2) has spread into the connective tissue layer of the esophagus wall, and cancer is found in 1 or 2 lymph nodes near the tumor; or (3) has spread into the diaphragm, pleura (tissue that covers the lungs and lines the inner wall of the chest cavity), or sac around the heart. The cancer can be removed by surgery. In stage IIIB, cancer has spread into the connective tissue layer of the esophagus wall. Cancer is found in 3 to 6 lymph nodes near the tumor. In stage IIIC, cancer has spread (1) into the diaphragm, pleura, or sac around the heart. The cancer can be removed by surgery. Cancer is found in 1 to 6 lymph nodes near the tumor; or (2) into other nearby organs, such as the aorta, trachea, or spine, and the cancer cannot be removed by surgery; or (3) to 7 or more lymph nodes near the tumor.
