Types of Esophageal Cancer

1. Squamous Cell Carcinoma: It is a type seen in the upper part of the esophagus and usually develops due to smoking and alcohol use.
2. Adenocarcinoma: It occurs in the lower part of the esophagus and is often associated with gastroesophageal reflux disease (GERD).

Diagnostic Methods

The following methods are used to diagnose esophageal cancer in Cuba:

• Endoscopy and Biopsy: Visualization of the inside of the esophagus and detection of the presence of cancer cells.
• Imaging Methods:
  • Computed Tomography (CT): Used to assess the size and extent of the tumor.
  • Magnetic Resonance Imaging (MRI): Determines the relationship of the tumor with surrounding tissues.
  • Positron Emission Tomography (PET): Used for the detection of metastases.

Treatment Methods

1. Surgical Treatment

• Partial or Total Resection of the Esophagus: Surgical removal of the area where the tumor is located. It is a preferred method for early stage cancers.
• Minimally Invasive Surgery: Less invasive procedures performed with laparoscopic techniques.

2. Radiotherapy

• Internal (Brachytherapy): Placement of radiation sources directly at the tumor site.
• External Radiotherapy: External radiation to the tumor site can be used before or after surgery.

3. Chemotherapy

• Neoadjuvant Chemotherapy: It is applied to shrink the tumor before surgery.
• Adjuvant Chemotherapy: Preferred to reduce the risk of metastasis after surgery.

4. Targeted Treatment

Targeted therapy involves the use of drugs directed at specific molecular targets of cancer cells. Cuba is conducting important research in this area and has developed some biotechnological drugs.

5. Immunotherapies

Immunotherapies, which fight cancer cells by strengthening the immune system, have gained attention in Cuba in recent years. This treatment method aims to create an immune response against tumor antigens.

Cuba's Vaccine and Drug Development Processes

Cuba pursues a policy aiming for self-sufficiency in the field of health. In this context, cancer vaccines and therapeutic drug development processes play an important role.

Cancer Vaccines

Cuba is a pioneer in developing vaccines against various types of cancer. In particular CIMAvax-EGF The vaccine aims to inhibit the growth of cancer cells and is used specifically in the treatment of lung cancer. The vaccine is also being studied in esophageal cancer and may help the immune system respond more effectively to cancer cells.

Biotechnological Medicines

Cuba has developed several innovative medicines in the field of biotechnology. Heberferon and EGF Biotechnological products, such as biotechnologics, offer new approaches to cancer treatment. These drugs are effective ways to inhibit the growth of tumors and improve patients' quality of life.
