Esophageal Cancer

Pathology

Esophageal cancer is a rare malignancy, ranking 8th in incidence worldwide, but it is a complex disease. It occurs more frequently in men and in people over the age of 60. The cancer develops when cells lining the esophagus acquire mutations and begin to grow uncontrollably. In most cases, the tumor originates in the mucosa of the esophagus or its glands, while less commonly it arises 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, in some cases, lead to the development of tumors several decades later.

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, the physician 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) may be taken for histological examination.

Radiological Examinations

Chest and abdominal X-rays with a transit study, along with computed tomography (CT) scans, provide detailed images of the esophagus and surrounding structures, helping 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 absorb labeled glucose and allows more confident localization of disease sites and extent, particularly in cases where findings from CT scans are uncertain.

 

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

Ear, Nose, and Throat (ENT) examinations are used to rule out, in cases of esophageal squamous cell carcinoma, the presence of synchronous tumors in the oral cavity, which share common risk factors for esophageal disease, such as cigarette smoking and alcohol consumption.

Laboratory Examinations

Blood tests can provide information about the patient’s overall health and assess the function of various organs. Tumor markers, specifically CEA and CA 19-9, are also measured; although they are not specific to esophageal cancer and may be elevated in other conditions, they can serve as general indicators of tumor activity but cannot be used as definitive diagnostic tests 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): an endoscopic procedure to remove superficial or precancerous lesions of the esophagus without the need of open surgery
  • Endoscopic Dissection Stretched to the Submucosa (ESD): an advanced endoscopic technique to remove larger, invasive tumors that extend to the submucosa of the esophagus

Surgical Treatment

The surgical approach is based on esophagectomy, which is the partial or total surgical removal of the esophagus. This procedure can be performed through a traditional open incision or using minimally invasive techniques, such as laparocopic, thoracoscopic or robotic surgery. Depending on the location of the tumor, the surgery may involve the abdomen, chest, and in some cases, the neck.

Because esophagectomy is a highly complex procedure, it is essential to carefully select patients who can safely tolerate the surgery and to ensure thorough preoperative preparation. For this reason, esophagectomy is performed only in centers with experienced multidisciplinary teams and a high volume of such procedures each year.

After removing the portion of the esophagus affected by the tumor, the esophageal tract must be reconstructed, typically using a portion of the stomach (esophago-gastric anastomosis) or another section of the intestine. Regional lymph nodes are also removed during the procedure to evaluate 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: administered before surgery to shrink the tumor and improve the likelihood of a successful outcome.
    • Adjuvant treatment: given after surgery to eliminate any remaining cancer cells and reduce the risk of recurrence.
    • Perioperative treatment: administered both before and after surgery.
    • Palliative treatment: used when the tumor has metastasized to other organs, aiming to relieve symptoms, improve quality of life, and extend survival.

Radiotherapy

Radiation therapy uses high-energy beams to destroy cancer cells. In the treatment of esophageal cancer, it can be combined with chemotherapy as neoadjuvant therapy before surgery to shrink the tumor or as adjuvant therapy after surgery to reduce the risk of local recurrence.

For inoperable tumors, radiation therapy may be used alone or alongside chemotherapy with a curative intent.

In patients with locally advanced esophageal cancer, it can also be employed palliatively to alleviate pain or difficulty swallowing (dysphagia).

Therapies

The treatment of esophageal cancer involves multiple therapeutic approaches, which may be used alone or in combination, depending on the tumor stage, patient characteristics, and overall clinical condition.

Multi Disciplinary Team

Every cancer requires a multidisciplinary approach at all stages of disease management. At the Candiolo Cancer Institute, this is provided by a team of specialists from various clinical and surgical departments, known as the GIC (Interdisciplinary Care Group or MDT). The GIC ensures that each patient is supported throughout the diagnostic and therapeutic process, including arranging and coordinating examinations and maintaining communication with the patient and their family.

For each patient, the GIC (MDT) defines and shares a personalized care pathway based not only on the type and stage of the tumor but also on the patient’s individual characteristics. The goal is to achieve the best possible outcomes both oncologically and functionally, while maintaining a high quality of life.

The Group also collaborates closely with the Institute’s researchers to provide patients with rapid access to the latest innovations in screening, diagnosis, and treatment.

Clinical divisions

The diagnostic and therapeutic pathway of esophageal cancer at Candiolo involves several clinical divisions, including:

Clinical studies

Researchers at the Candiolo Cancer 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.
