• #1 Diagnostics and Early Diagnosis of Esophageal Cancer

  https://pmc.ncbi.nlm.nih.gov/articles/PMC4789940/

  In the esophagus two different kinds of primary neoplasias may arise: squamocellular carcinomas (SCC) and esophageal adenocarcinomas (EAC). […] The management of esophageal cancer is challenging. There are no specific symptoms of early esophageal cancers. Due to this fact, most of the esophageal cancers are found incidentally, and only 12.5% of esophageal tumors are endoscopically resectable. Gastroscopy is the gold standard for the diagnosis of esophageal cancer. […] The diagnosis of esophageal cancer can be verified with targeted biopsies. Accurate staging information is crucial for establishing appropriate treatment choices for esophageal cancer, while the depth of the tumor determines the feasibility of therapy. […] In terms of staging, endosonography, abdominal ultrasound, and computed tomography scan of the thorax and abdomen should thus be performed before initiation of therapy.

  Diagnosis is the process of finding out the cause of a health problem. Diagnosing esophageal cancer usually begins with a visit to your family doctor. Your doctor will ask you about any symptoms you have and may do a physical exam. Based on this information, your doctor may refer you to a specialist or order tests to check for esophageal cancer or other health problems. […] The following tests are usually used to rule out or diagnose esophageal cancer. Many of the same tests used to diagnose cancer are used to find out the stage (how far the cancer has progressed). Your doctor may also order other tests to check your general health and to help plan your treatment. […] A physical exam allows your doctor to look for any signs of esophageal cancer. During a physical exam, your doctor may: check if your voice is hoarse, feel the lymph nodes above the collarbone and in the neck to check for swelling, feel the abdomen for enlarged organs or a buildup of fluid in the abdomen (called ascites), check the spine for any pain in the bones of the spine.

  An upper GI series is often the first diagnostic test used to check for esophageal cancer. It can show: a break in the surface of the esophagus (called ulceration), narrowing of the esophagus (called a stricture), the location and general size of a tumour in the esophagus, an abnormal opening from the esophagus into the trachea (called tracheoesophageal fistula), how well you can swallow, if the cancer has spread to the stomach. […] An upper GI endoscopy is done to examine the upper gastrointestinal tract, including the esophagus, stomach and the first part of the small intestine (called the duodenum). It uses an endoscope, which is a flexible tube with a light and lens on the end. […] EUS is often done at the same time as an upper GI endoscopy. […] A CT scan is used to look at the chest and abdomen to find out the size and location to help stage an esophageal tumour. It is also used to look for cancer that has spread to the nearby lymph nodes, liver, lungs or adrenal glands.

  Biopsy. This may be done during an upper endoscopy. […] Used alone, a barium swallow can’t diagnose cancer. But it can show abnormal areas that might need to be biopsied. […] This test can be used to find out if you have cancer in the esophagus. It can also show the size of the tumor. […] The pathologist can see if there are cancer cells in the tissue sample. If so, other tests are done to learn more details about the cancer. These include how fast it’s growing and if there are certain gene changes in the cancer cells. […] Your healthcare provider will contact you with your test results. Other imaging tests and blood tests will likely be needed if cancer is found. Make sure you understand your results and what happens next.

• #1 Esophageal Cancer Workup: Approach Considerations, Imaging Studies, Staging

  https://emedicine.medscape.com/article/277930-workup

  In 2013, the Society of Thoracic Surgeons released clinical practice guidelines to assist in the diagnosis and treatment of localized esophageal cancer. Their recommendations for diagnosis include the following: Flexible endoscopy with biopsy is the primary method for diagnosis of esophageal cancer. Computed tomography (CT) of the chest and abdomen is an optional test for staging of early-stage esophageal cancer, and a recommended test for staging of locoregionalized esophageal cancer. Positron emission tomography (PET) is an optional test for staging of early-stage esophageal cancer, and a recommended test for staging of locoregionalized esophageal cancer. In patients without metastatic disease, endoscopic ultrasonography is recommended to improve the accuracy of staging. In patients with small, discrete nodules or areas of dysplasia in whom disease appears limited to the mucosa or submucosa as assessed by endoscopic ultrasonography, endoscopic mucosal resection should be considered as a diagnostic/staging tool. In patients with locally advanced (T3/T4) adenocarcinoma of the esophagogastric junction infiltrating the anatomic cardia or Siewart type III esophagogastric tumors, laparoscopy is recommended to improve the accuracy of staging.

  After the diagnosis is confirmed with endoscopic biopsies, additional laboratory studies may be helpful in evaluating the tumor stage. […] The NCCN recommends evaluating for anemia with a complete blood count, which will influence therapy if the patient requires chemotherapy. […] Positron emission tomography (PET) and computed tomography (CT) have specific roles in providing important staging information. […] If there are no distant metastases, endoscopic ultrasonography should be performed to determine the tumor depth of invasion and nodal involvement, which are both useful in providing prognostic information and guiding treatment options. […] Accurate staging is important to establish the best treatment options. […] The most recent edition of the American Joint Committee on Cancer’s Cancer Staging Manual released in 2010 continues to use the tumor-node-metastasis classification but also includes other prognostic variables.

  A PET scan is used to look for very small tumours in the chest or abdomen that may have spread from an esophageal cancer. […] A laparoscopy is used to accurately stage esophageal cancer so doctors can plan treatment. It may find cancer that has spread to other parts of the abdomen that wasn’t seen on a PET or CT scan. […] HER2 status testing is done on esophageal tumours found where the esophagus and stomach join (called the gastroesophageal, or GE, junction). This information will help your healthcare team decide which treatments will work best for you.

• #1 Esophageal Cancer Workup: Approach Considerations, Imaging Studies, Staging

  https://emedicine.medscape.com/article/277930-workup

  Imaging studies used in the diagnosis and staging of esophageal cancer include the following: CT scanning, PET scanning, Endoscopic ultrasound (EUS), Bronchoscopy, Barium swallow. […] EUS is the most sensitive test for determining the depth of tumor penetration (T staging) and the presence of enlarged periesophageal lymph nodes (N staging). The accuracy of diagnosing nodal disease is significantly increased with the combination of above-mentioned features, but also is confirmed with the use of fine needle aspiration (FNA) biopsy for cytology assessment. The combined use of EUS and FNA (EUS-FNA) has a greater accuracy than EUS alone in the evaluation of lymph node metastasis. […] Upper GI endoscopy allows direct visualization and biopsies of the tumor. Endoscopy is a very important tool in the diagnosis, staging, and surveillance of patients with esophageal cancer. Most endoscopy procedures are performed under conscious sedation. Patients who are at risk of aspiration during endoscopy may require general anesthesia.

  Esophageal tumor length, as assessed by preoperative endoscopy, has been identified as an independent predictor of long-term survival in patients with adenocarcinoma of the esophagus. The 5-year survival rate was significantly higher for patients with a tumor length of 2 cm or less (78% vs 29% for those with a tumor length of more than 2 cm). […] Endoscopic resection (ER) of focal nodules should be performed in the setting of early-stage disease (T1a or T1b) to provide accurate assessment of depth of invasion, degree of differentiation, and the presence of lymphovascular invasion. Thus, ER is an essential procedure for the accurate staging of early-stage cancer especially in patients with small nodular lesions (2 cm).

[…] Esophageal cancer biopsy procedures include: […] The stage of esophageal cancer indicates how advanced the tumor is and if it has spread. It also informs your care team about potential treatment options. The most common system used to stage esophageal cancer is the TNM system. […] Staging also takes into account the cell type of the cancer, grade of the cancer and, in some cases, location of the tumor. […] The overall stage of a cancer is a combination of the key elements described above. Cancer stages range from stage 0 (pre-cancer) to stage IV (advanced cancer.) […] The grade of a cancer is based on how normal (or differentiated) the cells appear when they are looked at under the microscope. The higher the number, the more abnormal the cells look. Higher-grade tumors tend to be more aggressive, spreading faster than lower-grade tumors.

  A positron emission tomography (PET) scan shows cancer growth in other parts of the body by means of a substance called radionuclide glucose (sugar), which is injected into a vein. This substance is taken up by cancer cells because they use sugar more readily than normal cells do. In some instances, both a PET scan and a CT scan will be used to determine if the cancer has spread beyond the esophagus. […] Treatment for esophageal cancer has improved significantly with advances in imaging technology and more precise staging of the disease. […] Treatment will depend on the size and extent (stage) of the tumor, its location and your overall general health.

  https://emedicine.medscape.com/article/277930-workup

  Imaging studies used in the diagnosis and staging of esophageal cancer include the following: CT scanning, PET scanning, Endoscopic ultrasound (EUS), Bronchoscopy, Barium swallow. […] EUS is the most sensitive test for determining the depth of tumor penetration (T staging) and the presence of enlarged periesophageal lymph nodes (N staging). The accuracy of diagnosing nodal disease is significantly increased with the combination of above-mentioned features, but also is confirmed with the use of fine needle aspiration (FNA) biopsy for cytology assessment. The combined use of EUS and FNA (EUS-FNA) has a greater accuracy than EUS alone in the evaluation of lymph node metastasis. […] Upper GI endoscopy allows direct visualization and biopsies of the tumor. Endoscopy is a very important tool in the diagnosis, staging, and surveillance of patients with esophageal cancer. Most endoscopy procedures are performed under conscious sedation. Patients who are at risk of aspiration during endoscopy may require general anesthesia.
