The 7 th edition stage groupings were also defined to consider the importance of histopathologic cell type, tumor grade, and tumor location. Table 2 shows stage grouping for adenocarcinoma and squamous cell carcinoma, which are no longer equivalent in the 7 th edition. The Society of Thoracic Surgeons has published guidelines on the diagnosis and staging of patients with esophageal cancer The work-up for esophageal cancer often starts when patients present with symptoms such as dysphagia and weight loss in the setting of an unremarkable physical exam 2 , Therefore, the most common tests used to initially identify and diagnosis esophageal cancer are upper gastrointestinal GI tract contrast studies and upper endoscopy with biopsy.

An upper GI contrast study typically shows a stricture or ulceration when malignancy is present.

Stages of Esophageal Cancer and Treatments

Upper GI endoscopy identifies tumor location and length and allows biopsy for pathologic examination. After a histologic cancer diagnosis has been obtained, subsequent studies are performed to determine clinical stage as accurately as possible before treatment is initiated. Obtaining a computed tomographic CT scan of the chest and abdomen with both oral and intravenous contrast should be the first staging study when esophageal cancer is diagnosed histologically.

The CT scan is somewhat limited in defining the local extent and nodal involvement of esophageal cancer but is most useful in identifying the presence of distant disease such as liver or lung metastases. Further studies that evaluate T and N status would not typically impact treatment and therefore are generally unnecessary if distant disease is identified and subsequently confirmed by biopsy. However, EUS is less accurate for early-stage lesions such as T1 or T2 compared to more advanced tumors 18 - Most incidences of understaging are due to missing nodal disease.

Performance of the above staging modalities establishes the pre-treatment clinical stage which can be used to guide subsequent treatment, as will be discussed in the following sections. However, occasionally additional studies may be worthwhile before initiation of treatment. First, bronchoscopy should be considered for tumors in the upper and middle esophagus to rule out airway invasion. CT scan and EUS can be suggestive of airway involvement but are not as accurate as direct visualization of the airway.

In addition, distant metastases are unfortunately missed even with completion of the staging evaluation described above. Small liver or lung metastases can be missed by both PET and CT scans, and patients can also have undetected pleural or peritoneal disease Staging via minimally invasive surgical techniques of thoracoscopy and laparoscopy improves the accuracy of the above non-invasive testing 23 - Use of these invasive techniques is relatively uncommon but should be considered in select patients, such as those who may be considered to have a high risk of treatment-related complications.

Staging laparoscopy in particular may have a role for patients with adenocarcinoma of the esophagus or esophagogastric junction Treatment options include local mucosal resection or ablation therapies, esophagectomy, chemotherapy, and radiation therapy. However, definitive data from randomized trials to guide the treatment of esophageal cancer is lacking for many clinical situations. Outcomes also generally are relatively poor with many treatment strategies, so establishing optimal treatment for different clinical situations remains an area of active research The NCCN guidelines reflect the lack of definitive evidence and often allow a spectrum of potential treatments for many clinical situations.

Given both the generally poor overall prognosis and the potential morbidity associated with therapy, multidisciplinary evaluation by surgery, medical oncology, and radiation oncology should be considered for all patients before a treatment strategy is initiated. Treatment that does not follow guidelines should probably only be used in the context of clinical trials. The stage groupings described above are very useful for both providing prognosis and guiding treatment. However, patients can be categorized even more simply when considering treatment.

When considering treatment for esophageal cancer patients, the approach is initially dictated by whether the patients have been determined to have early stage superficial cancers, cancers that are locally advanced with locoregional disease but no distant metastases, and cancers with distant disease. The general treatment guidelines for each of these categories will be discussed in the following sections. Patients with TN0 esophageal cancer typically are recommended to undergo surgery without induction treatment The prognosis for patients treated for intra- and submucosal T1 esophageal cancers is significantly better than the prognosis for all other patients found to have esophageal cancer, even those also found in other relatively early-stage disease 8.
