Pathology
Esophageal cancer is a rare neoplasm, ranked 8th in incidence worldwide, but it presents as a complex disease. It affects men and people over the age of 60 more frequently. It develops when cells lining the esophagus undergo mutations and begin to multiply uncontrollably. In most cases, the origin of the tumor can be traced to the mucosa of the esophagus or the glands within it; more rarely, it may develop from the muscle layer.
The most common forms of esophageal cancer are:
- Squamous cell carcinoma, more related to alcohol consumption and smoking, with higher incidence in specific geographic areas
- Adenocarcinoma, frequently associated with gastroesophageal reflux and obesity
The numbers in Italy
According to the latest data from the AIRTUM (Italian Association of Cancer Registries) registry, esophageal cancer recorded about 2,480 new diagnoses (1,740 men and 740 women) in 2022.
Risk factors
Specific risk factors vary according to different geographical areas of origin. The most commonly encountered risk factors in Europe are:
- smoking and alcohol
- obesity
- gastro-oesophageal reflux
- Barrett’s esophagus
- ingestion of caustic products, resulting in burns, can lead, in some cases, to tumor development in subsequent decades.
Symptoms
Initial symptoms may be mild or absent. When present, these are often symptoms that are not specific to esophageal cancer because they are also caused by other conditions. Therefore, in the presence of these symptoms, it will be the physician who will assess whether to request further investigation with any additional tests such as blood tests and possibly a gastroenterological examination with esophagogastroduodenoscopy.
The most common symptoms include:
- Difficulty swallowing (dysphagia)
- Unintentional weight loss
- Coughing and vomiting with blood emission
- Regurgitation, hoarseness, persistent coughing
- Thoracic or retrosternal pain
Diagnosis and examination
Early detection of esophageal cancer is critical to increase the chances of cure and improve the patient’s prognosis.
Esophagogastroduodenoscopy
Esophagogastroduodenoscopy (EGDS) is a fundamental examination for the diagnosis of esophageal cancer. It consists of the introduction of a Thin flexible tube with a camera on the end (endoscope) through the mouth To directly visualize the esophagus. During endoscopy, tissue samples (biopsy) can be taken for histological examination.
Radiological examinations
The radiographs of the chest and abdomen with transit study and computed tomography (CT) scan can provide detailed images of the esophagus and surrounding structures to assess the extent of the tumor.
Ecoendoscopy
This procedure combines endoscopy with ultrasound to obtain high-resolution images of the walls of the esophagus and surrounding lymph nodes.
Positron Emission Tomography (PET)
This examination provides information on the tumor’s ability to pick up labeled glucose and enables the more confidently localize the sites and extent of disease, sometimes doubtful after CT scans have been performed.
Bronchoscopy
It is a endoscopic examination of the airways (trachea and bronchi) and is used to evaluate, in selected cases, direct involvement of these structures by esophageal neoplasia.
ENT examination
It is used to exclude in esophageal squamous cell carcinomas any synchronous tumors of the oral cavity which find, in cigarette smoking and alcohol intake, the same agents favoring the onset of esophageal disease.
Laboratory examinations
Blood tests can provide information about the patient’s general health status and assess organ function. Tumor markers, namely CEA and Ca19.9, are also assayed: they are not specific for esophageal cancer and can also be detected in other conditions; they can, therefore, be used as a general indicator of tumor activity, but not as a definitive diagnostic test for esophageal cancer.
Histological examination
Histologic examination is a process in which a pathologist carefully examines samples taken during an endoscopy under a microscope to identify any cellular abnormalities that may indicate the presence of esophageal cancer. They are, therefore, defined:
- The type of tumor (adenocarcinoma or squamous cell carcinoma);
- the “histological grade” or grading: describes the appearance of tumor cells under the microscope and indicates the degree of cell differentiation and how quickly they can grow;
- biomarkers, i.e., assessment by immunohistochemical techniques of protein expression on tumor cells on the biopsy that represent a prognostic and/or predictive factor for response (e.g., PDL1, HER2 only in selected cases).
Staging
Esophageal cancer staging is essential to determine the extent of disease and plan treatment. Using diagnostic test results, a stage is assigned to the tumor, such as stage 0 (carcinoma in situ) to stage IV (distant spread). Specifically:
Endoscopic treatment
Endoscopic treatment is often considered for early esophageal cancers, particularly carcinoma in situ or superficial tumors. These treatment options include:
- Endoscopic Mucosal Resection (EMR): is an endoscopic procedure to remove superficial or precancerous lesions of the esophagus without the need for open surgery;
- Endoscopic Dissection Stretched to the Submucosa (ESD): is an advanced endoscopic technique to remove larger, invasive tumors that extend to the submucosa of the esophagus.
Surgical treatment
The surgical approach is based onesophagectomy, which is thepartial or total surgical removal of the esophagus. It can be performed through atraditional incision (open surgery) or through a minimally invasive approach (laparo/thoracoscopic or robotic). Depending on the site of the neoplasm, surgery may require an abdominal, thoracic, and sometimes cervical approach.
Because it is a very complex procedure, it is crucial to identify patients who can tolerate this procedure and perform adequate preparation for surgery. For these reasons, esophagectomy is performed only in centers with experienced multidisciplinary teams and in centers that perform a high number of such procedures per year.
Following removal of the esophageal tract affected by the neoplasm, it is necessary to reconstruct the esophageal tract by using a portion of the stomach (esophago-gastric anastomosis) or another intestinal tract. During esophagectomy, removal of regional lymph nodes is also performed to assess the extent of the tumor and reduce the risk of metastatic spread.
Chemotherapy
Chemotherapy can be used in several settings in the treatment of esophageal cancer, including:
-
- Neoadjuvant treatment: is administered before surgery to reduce tumor size and increase the chance of successful treatment;
-
- Adjuvant treatment: is performed after surgery to destroy any remaining cancer cells and reduce the risk of recurrence;
-
- perioperative treatment: is administered before and after surgery;
-
- palliative treatment: when the tumor has spread to other organs, so it is metastatic, to relieve disease symptoms, improve quality of life and prolong survival.
Radiotherapy
Radiation therapy uses high-energy beams to destroy cancer cells. In the treatment of esophageal cancer, radiation therapy can be used in combination with chemotherapy as a neoadjuvant treatment before surgery to reduce the tumor mass or as an adjuvant post-surgical treatment to reduce the risk of local recurrence.
In the case of inoperable tumor lesions, radiation therapy can be used alone or in combination with chemotherapy for radical purposes.
In patients with locally advanced esophageal tumors, it can also be used for palliative purposes to reduce any algic or dysphagic symptoms.
Therapies
Treatment of esophageal cancer involves several therapeutic modalities, which can be used individually or in combination, depending on the stage of the tumor, patient characteristics, and clinical conditions.

Interdisciplinary Group
Every cancer requires, in all phases of disease management, a multidisciplinary approach that at the Candiolo Institute is guaranteed by a team of different specialists, belonging to the various clinical and surgical departments of the Institute: this team is called GIC (Interdisciplinary Care Group). The GIC ensures that each patient is taken care of throughout the diagnostic-therapeutic process, including prescribing and booking examinations and communicating with the patient and his or her family members. The GIC defines and shares a personalized care pathway for each patient, based not only on the type and stage of the tumor, but also on the patient’s own characteristics. The goal is to ensure that he or she has the best outcome both oncologically and functionally and the maintenance of a good quality of life.The Group also works closely with researchers at the Institute to ensure that patients have rapid access to the latest research-produced innovations in screening, diagnosis and treatment.
Clinical divisions
The diagnostic and therapeutic pathway of esophageal cancer at Candiolo involves several clinical divisions, including:
- Oncologic surgery
- Otolaryngology
- Gastroenterology and digestive endoscopy
- Anesthesia and resuscitation
- Oncology day hospital
- Medical oncology
- Nuclear medicine
- Radiotherapy
- Radiodiagnostics
- Pathologic anatomy
Clinical studies
Researchers at the Candiolo Institute are currently involved in several national and international projects on esophageal cancers.
The GEA study is a multicenter study. It aims to explore the mechanisms of response of gastro-oesophageal cancer to treatment with so-called “targeted” drugs. After the patient has provided informed consent, unused surgical material after histologic analysis is used to generate molecularly characterized preclinical models (xenopatients) on which to validate drug combinations. The aim is to gain new insights into the interaction between the tumor genome and the efficacy of the therapy patients are subjected to, so as to understand what mechanisms may underlie different drug response and tumor progression.
