esophagus sarcoma

Esophageal sarcoma is a rare and aggressive form of cancer that affects the esophagus, a long, hollow tube that runs from the throat to the stomach [1]. It represents less than 1% of all malignant tumors of the esophagus [3].

There are several types of esophageal sarcomas, including:

• Carcinosarcoma: A rare and aggressive form of cancer that combines features of both carcinomas (cancerous epithelial cells) and sarcomas (cancerous connective tissue cells) [2].
• Leiomyosarcoma: A type of cancer that arises from the smooth muscle cells in the esophagus wall [3].
• Sarcomatoid carcinoma: An uncommon malignancy that represents approximately 2% of esophageal carcinomas [5].

Esophageal sarcomas often present as an intraluminal polypoid lesion in the esophageal lumen, and can cause symptoms such as difficulty swallowing (dysphagia) and weight loss [6]. They are typically treated with a combination of surgery, chemotherapy, and radiation therapy.

It's worth noting that esophageal sarcomas are rare and account for only 0.1%–1.5 % of all esophageal cancers [2].

Esophageal cancer, also known as esophageal carcinoma, is a type of cancer that affects the esophagus, which is the tube-like structure that carries food from the mouth to the stomach.

Common symptoms of esophageal cancer:

• Difficulty swallowing (dysphagia): As the tumor narrows the passage in the esophagus, pushing food through becomes harder. This is often the first symptom of esophageal cancer to appear [8].
• Vomiting: A person vomits food after it gets stuck in the esophagus due to the tumor's growth [8].
• Chest pain: Pain or discomfort in the chest area can be a symptom of esophageal cancer, especially if the tumor has grown large enough to press on surrounding nerves and muscles [2].
• Weight loss: As food becomes harder to swallow and digest, people with esophageal cancer may experience unintended weight loss [2].
• Hoarseness or coughing: If the tumor grows large enough to affect nearby structures, such as the vocal cords or lungs, hoarseness or persistent coughing can occur [5].

Other possible symptoms:

• Painful swallowing (odynophagia): As the tumor grows and presses on surrounding tissues, eating and swallowing can become painful [10].
• Bleeding into the esophagus: In some cases, bleeding from the esophageal lining can occur due to the tumor's growth [2].

Important note: Esophageal cancer often has no warning signs in its early stages. Symptoms may not appear until the disease is advanced and harder to treat.

Diagnostic Tests for Esophageal Cancer

Esophageal cancer diagnosis often begins with imaging tests to look at the esophagus. A combination of tests can be used to diagnose and stage esophageal cancer.

• Endoscopy: This is a test that looks at the lining of your esophagus, stomach, and upper part of your small intestine (duodenum). It's often performed with a biopsy to check for cancer cells.
  • [5] Endoscopy with biopsy: Sometimes called an esophagogastroduodenoscopy or EGD, this is the most common test a doctor will perform to test for esophageal cancer.
• Imaging tests: These use x-rays, magnetic fields, sound waves, or radioactive substances to create pictures of the inside of your body. Imaging tests might be done for a number of reasons both before and after a diagnosis of esophageal cancer, including:
  • [11] To look at a suspicious area that might be cancer
• Barium swallow study: This test uses X-rays to look at the digestive system.
  • [10] A barium swallow study is a test that uses X-rays to look at the digestive system.
• Endoscopic ultrasound (EUS): This test uses sound waves to create images of the esophagus and surrounding tissues. It can help identify tumors or other abnormalities.
  • [1] An endoscopic ultrasound can show enlarged lymph nodes, which may indicate a tumor or advanced disease.
• Computed tomography (CT) scan: A CT scan uses X-rays to take detailed pictures of the inside of your body.
  • [2] X-rays · CT (computed tomography) scans · MRI (magnetic resonance imaging) scans · PET (positron emission tomography) scans.
• Positron emission tomography (PET) scan: This test uses a radioactive substance to create images of the esophagus and surrounding tissues. It can help identify cancer cells or other abnormalities.

Additional Tests

• Blood tests: These can detect elevated liver enzymes, which could mean the cancer has spread to your liver.

Staging and Prognosis

After a cancer diagnosis, staging provides important information about the extent of cancer in the esophagus. Staging can help determine the best treatment options and outlook (prognosis).

Chemotherapy, Targeted Therapy, and Immunotherapy for Esophageal Sarcoma

Esophageal sarcoma, a rare type of cancer affecting the esophagus, can be treated with various drug therapies. The most common treatment options include:

• Chemotherapy: This involves using medications to kill cancer cells. Chemotherapy can be used alone or in combination with other treatments like radiation therapy and surgery.
• Targeted Therapy: Targeted therapy uses drugs that specifically target the weaknesses of cancer cells, reducing harm to healthy cells. For esophageal sarcoma, targeted therapy may involve drugs that target specific genetic mutations or proteins involved in cancer growth.
• Immunotherapy: This type of treatment stimulates the immune system to recognize and attack cancer cells. Immunotherapy can be used alone or in combination with other treatments.

Treatment Approaches

The choice of drug treatment for esophageal sarcoma depends on various factors, including:

• The stage and location of the tumor
• The patient's overall health and medical history
• The presence of any genetic mutations or biomarkers that may influence treatment response

Current Research and Developments

Ongoing research aims to develop more effective targeted therapies with minimal side effects. This includes investigating new drugs and combinations of existing treatments.

Differential Diagnosis of Esophageal Sarcoma

Esophageal sarcoma, a rare and aggressive type of cancer, can be challenging to diagnose due to its similarity in presentation with other conditions. The differential diagnosis for esophageal sarcoma includes:

• Sarcomatoid squamous cell carcinoma: A principal differential diagnosis that can be differentiated by combining specific markers [2][5].
• Adenoid cystic carcinoma: An important differential diagnosis with a better prognosis, which requires careful consideration of clinical and histopathological features [6].
• Verrucous carcinoma: A slow-growing exophytic tumor that may mimic the appearance of esophageal sarcoma.
• Gastrointestinal stromal tumors (GISTs): Can be differentiated from esophageal sarcomas by specific immunohistochemical markers and molecular characteristics.
• Small round cell tumors: Including small-cell carcinoma, which can present with similar symptoms and require careful differentiation [9].

Key Points to Consider

• The diagnosis of esophageal sarcoma often requires a combination of clinical presentation, endoscopic findings, and histopathological examination.
• A thorough differential diagnosis is essential to rule out other conditions that may mimic the presentation of esophageal sarcoma.
• Specific markers and molecular characteristics can aid in differentiating esophageal sarcomas from other types of cancer.
