Hypopharynx and Proximal Esophagus

Part of the Medical Radiology book series (MEDRAD)


Cancers of the hypopharynx and proximal esophagus typically present at an advanced stage. They are often underestimated on clinical examination as they tend to grow in a submucosal fashion. On imaging, evaluation of the normally present fat planes within the post-cricoid musculature and around the hypopharynx as well as proximal esophagus is essential for mapping of the tumor boundaries. Cartilage invasion, tumor volume and involvement of the pyriform sinus apex are important variables in stratification of patients into favorable and unfavorable treatment groups. Patients with favorable tumors typically receive radiation therapy while patients with unfavorable tumors usually undergo surgical resection and subsequent reconstructive surgery. Both treatments cause some alteration of the tissue planes with additional marked distortion of the normal anatomy seen with surgical resection. The growth patterns of tumors arising from the different subsites within the hypopharynx and proximal esophagus, pretreatment considerations for staging and treatment planning purposes, as well as posttreatment complications and surveillance issues will be discussed in this chapter.
