Thymoma Symptoms and Diagnosis

Being aware of thymoma symptoms and diagnosis is crucial, says Dr Harsh Vardhan Puri. Early and accurate diagnosis can be aided by recognising symptoms such as pressure in the chest, pain or incidental finding.

Thymoma And Thymic Carcinoma

Cancers that originate in the thymus gland include thymoma and thymic carcinoma. The thymus is situated posterior to the breastbone. It is crucial for the formation of T-lymphocytes, or T-cells, which are white blood cells that fight infection.

Epithelial cells and lymphocytes are the two cell types that make up your thymus. Any kind has the potential to develop improperly and become cancer:

• Thymomas and thymic carcinomas are caused by abnormal development of epithelial cells.
• Hodgkin lymphoma and non-Hodgkin lymphoma are caused by abnormal lymphocyte proliferation.

Since thymic epithelial cells are the source of both thymoma and thymic carcinoma, both conditions are also known as thymic epithelial tumours (TETs) since they begin in the thymus.

What Is The Difference Between Thymoma And Thymic Carcinoma?

While both thymomas and thymic carcinomas are classified as thymic epithelial tumours (TETs), there are a few key distinctions between them:

• Thymoma seldom spreads outside of your thymus and develops slowly.
• Thymic carcinoma has a rapid rate of development and a higher propensity to metastasis, or spread to other body areas.

The prognosis and recommended therapies vary depending on whether you have more aggressive thymic cancer or less aggressive thymoma. Thymoma symptoms and diagnosis are important areas of interest for Dr Harsh Vardhan Puri. For improved patient treatment, early identification of symptoms such as exhaustion, dysphagia, and shortness of breath guarantees prompt and accurate diagnosis.

Who Does It Affect?

Adults aged 40 to 75 are most commonly affected by thymomas and thymic carcinomas. Most diagnosed individuals are of Asian descent.

Thymomas and autoimmune paraneoplastic diseases are often linked. Your body’s immune cells wrongly target healthy cells when you have an autoimmune paraneoplastic syndrome, which results in uncomfortable symptoms. The following paraneoplastic disorders are most often linked to thymoma:

• Myasthenia gravis is an autoimmune disease that causes muscles and nerves to weaken.
• A blood condition called pure red cell aplasia (PRCA) occurs when the bone marrow produces insufficient red blood cells. Anaemia is caused by PRCA.
• Good syndrome, also known as hypogammaglobulinemia, is an immune system condition in which the body is unable to produce enough antibodies to fend against infections and combat disease.

Less often, other paraneoplastic diseases linked to thymomas are:

• Rheumatoid arthritis
• Lupus erythematosus
• Sjögren syndrome
• Polymyositis
• Thyroiditis

Symptoms and Causes

In the early stages, most people don’t have any symptoms. Rather, symptoms usually appear when a tumour affects your chest’s organs. Paraneoplastic disorders are linked to additional symptoms. Dr Harsh Vardhan Puri emphasises the need of being vigilant when it comes to thymoma symptoms and diagnosis. For best results, symptoms such face puffiness, nocturnal sweats, and respiratory problems need to be diagnosed as soon as possible with precision.

Signs that a tumour is affecting a chest organ

Breathing problems and pain might indicate thymic cancer or thymoma. Among the symptoms are:

• Feeling as though something is pressing on your chest.
• A persistent cough.
• Breathlessness.
• Difficulty swallowing.

The vena cava, which is a major vein that supplies blood to the heart, can become blocked or squeezed by tumours. Superior vena cava syndrome is an extremely dangerous disorder that can result from compression of the vena cava. If this occurs, you could feel the following symptoms:

• Cough
• Breathlessness
• Weariness
• Lightheadedness
• Headaches
• Swelling of your face and neck
• Swelling of your hands and arms
• Veins that are visible on the upper torso

Paraneoplastic disorders’ indicators and symptoms

You may experience indications and signs of one or more paraneoplastic syndromes if you have a thymoma, such as:

• Muscle weakness, exhaustion, drooping eyelids, and double vision (myasthenia gravis).
• Pure red blood cell aplasia, or anaemia.
• Diarrhoea, lymph node swelling, and recurrent infections (hypogammaglobulinemia).

What Causes Thymoma (Thymic Carcinoma)?

Thymoma has no recognised hereditary or environmental risk factors. To find connections between viruses, heredity, and other malignancies, research is still being conducted.

Diagnosis and Tests

How Is Thymic Carcinoma (Thymoma) Diagnosed?

A tumour might be discovered after undergoing imaging tests to understand the reasons behind your symptoms. Dr Harsh Vardhan Puri will examine you physically and inquire about your symptoms and health history to make a diagnosis. To learn more about your tumour, he could recommend some of the following procedures:

• Chest X-ray: An X-ray can reveal internal body masses and offer crucial details, such as the degree of edge definition in a tumour. During surgery, it is simpler to remove a tumour with well-defined borders.

• CT scan: The most used imaging technique for thymoma detection is a CT scan of the chest. To increase the visibility of your tumour on imaging, your doctor may inject dye, also known as a contrast medium, into a vein. A CT scan is frequently all that is required for the diagnosis of thymoma or thymic cancer.

• MRI: An MRI can provide your doctor with a clear picture of your tumour and help them distinguish it from other possible growths. For instance, to determine if a lump is a thymoma or thymic cancer, your doctor could do an MRI.

• PET scan: Also known as a PET/CT, involves the safe injection of radioactive sugar into your veins by a medical professional. This mixture, also known as contrast media, gathers around high-energy cells, such as cancer cells. Tumours appear on imaging more clearly when the contrast medium is used. Providers may frequently do a PET scan and a CT scan at the same time, or PET/CT.

• Biopsy: A diagnosis can only be verified by a biopsy. Tumour cells will be extracted by your provider, who will then examine them under a microscope. Your doctor will eliminate the entire tumour and test the cells if it can be done safely. Your doctor will take a sample for testing if they are unable to safely remove the entire tumour.

Dr Harsh Vardhan Puri emphasises how crucial it is to comprehend thymoma symptoms and diagnosis. Early discovery and more successful treatment are possible when symptoms are recognised in time. If you are experiencing any of these symptoms, get in touch with Dr Harsh Vardhan Puri today.

FAQ

1. How is thymoma diagnosed?

Thymoma is typically diagnosed through a combination of imaging tests and biopsies. A chest X-ray or CT scan is often the first step in diagnosing a tumour in the thymus. If a tumour is found, a biopsy (tissue sample) may be performed to determine whether the tumour is benign or malignant. Additional tests, such as MRI or PET scans, may be used to assess the size, spread, and staging of the tumour. Blood tests can also help detect any associated conditions, such as myasthenia gravis, which often occurs with thymoma.

2. Is thymoma always cancer?

No, thymoma is not always cancerous. Thymomas can be benign (non-cancerous) or malignant (cancerous). Benign thymomas are localised and typically grow slowly without spreading to other parts of the body. Malignant thymomas, on the other hand, have the potential to invade nearby tissues or spread (metastasize) to other organs. Both types of thymoma require treatment, but the approach may differ depending on whether the tumour is benign or malignant.

3. What are the symptoms of stage 2 thymoma?

In stage 2 thymoma, the tumour has started to spread beyond the thymus into nearby tissues or structures, such as the fat surrounding the thymus or the lining of the lung. Common symptoms include chest pain, persistent cough, shortness of breath, and difficulty swallowing. Some individuals may experience fatigue, muscle weakness, and symptoms of myasthenia gravis, a condition commonly associated with thymomas. However, in some cases, thymomas may not produce noticeable symptoms until they grow larger.

4. What are the warning signs of thymus issues?

Warning signs of thymus problems, such as thymoma or thymic hyperplasia, may include persistent chest pain, chronic cough, shortness of breath, and difficulty swallowing. Muscle weakness, especially in the face and neck, and drooping eyelids are also common symptoms associated with thymus disorders like myasthenia gravis. Unexplained weight loss and fatigue may also be warning signs. In some cases, thymus problems may be asymptomatic and only discovered through imaging for other conditions.

5. Can thymoma be cured?

Yes, thymoma can often be cured, especially if it is diagnosed at an early stage. Surgical removal of the tumour is the primary treatment and can be curative if the tumour is confined to the thymus (early-stage thymoma) specially by VATS and Robotic Surgery. For more advanced stages, additional treatments such as radiation therapy or chemotherapy may be needed after surgery to help prevent recurrence. The prognosis is generally good for early-stage thymomas, while later stages may require more aggressive treatment and ongoing monitoring.
