Although T2,N0,M0 esophageal adenocarcinoma is grouped with other locoregional disease by NCCN, no consensus exists about how it should be treated.

In addition, conflicting evidence exists about whether neoadjuvant therapy adds any benefit to esophagectomy. A 52-year-old patient recently seen at the Robert H. Lurie Comprehensive Cancer Center illustrates the complexity of these issues.

Neuroendocrine tumors (NETs) of unknown origin account for more than 10% of all NETs. Most of these tumors are poorly differentiated and, thus, very aggressive. Establishing the location of the primary tumor can be challenging. Workup of these NETs of unknown origin includes a thorough family history, immunohistochemistry, imaging, and OctreoScan. If the location of the primary malignancy is not determined, treatment is often initiated based on the grade and level of differentiation of the tumor, with well- and moderately differentiated tumors treated as carcinoid tumors, whereas poorly differentiated tumors are treated similarly to small cell tumors. Therapy is chosen based on symptoms and with the goal of debulking tumor when feasible and safe.
