Treatment of thymic tumors and VATS thymectomy

Dr. Mohammad Tarshihi – Consultant Thoracic Surgeon

What Is the Thymus Gland?

The thymus is a small gland located in the anterior mediastinum, just behind the sternum (breastbone). It plays a role in immune system development, especially during childhood.

In adults, the thymus may develop tumors, which can range from benign to highly aggressive malignant tumors.

The thymus gland is usually removed in two main cases:

  • The presence of tumors in the thymus gland

  • Treatment of myasthenia gravis

The thymus gland is located in the anterior mediastinum behind the sternum, and various types of tumors with varying degrees of aggressiveness can arise from it.

When Is Thymectomy Needed?

Removal of the thymus gland (thymectomy) is recommended in two main situations:

  • Presence of a thymic tumor

  • Treatment of myasthenia gravis, even without a tumor

Types of Thymic Tumors

Thymic tumors are classified into:

A → AB → B1 → B2 → B3 → C

  • Types A–B: usually less aggressive

  • Type B3: more aggressive behavior

  • Type C (Thymic carcinoma):

    • Rare but highly malignant

    • More invasive and may spread to other organs

يُعد استئصال الغدة الزعترية بالمنظار (VATS thymectomy) من أحدث وأفضل الطرق لعلاج أورام الغدة الزعترية والوهن العضلي الوبيل، حيث يتم إجراء العملية بدون فتح الصدر، مما يؤدي إلى ألم أقل وتعافي أسرع.

يقدم د. محمد الترشيحي – استشاري جراحة الصدر في الأردن هذا النوع المتقدم من العمليات بخبرة تمتد منذ عام 2007، مع نتائج ممتازة ونسب نجاح مرتفعة.

لماذا يُعتبر استئصال الغدة الزعترية بالمنظار الخيار الأفضل؟

  • بدون فتح عظم القص

  • ألم أقل بعد العملية

  • شقوق صغيرة

  • تعافي سريع (24–48 ساعة)

  • نتائج ممتازة

Clinical symptoms of thymus tumors

Symptoms of Thymic Tumors

Symptoms vary depending on tumor size and location:

  • Chest pain or discomfort behind the sternum

  • Persistent cough

  • Shortness of breath

  • Fatigue and reduced exercise tolerance

  • Muscle weakness (especially in myasthenia gravis)

  • Difficulty chewing or swallowing

  • Swelling of the face, neck, or upper body

  • Visible veins on the chest (superior vena cava syndrome)

⚠️ Important:
Small tumors are often discovered incidentally during imaging for other conditions.

 

Diagnosis

 

How Is the Diagnosis Made?

Accurate diagnosis requires advanced imaging and evaluation:

  • CT scan with contrast (most important test)

  • MRI of the chest (in selected cases)

  • PET scan or radioisotope imaging (for staging)

  • Ultrasound of supraclavicular lymph nodes

  • Blood tests and general health assessment

  • ECG and preoperative evaluation

These tests help determine:

  • Tumor size

  • Invasion into nearby organs

  • Lymph node involvement

  • Surgical feasibility

Treatment of Thymic Tumors

Treatment depends on:

  • Tumor size

  • Degree of invasion

  • Presence of metastasis

  • Patient’s overall condition

Main Treatment Options:

1. Surgery (Primary Treatment)

The most effective treatment is complete surgical removal (thymectomy).

2. Additional Therapies (if needed)

  • Radiotherapy

  • Chemotherapy

  • Targeted therapy

VATS Thymectomy (Minimally Invasive Surgery)

What Is VATS?

VATS (Video-Assisted Thoracoscopic Surgery) is a minimally invasive technique where the thymus is removed through small incisions using a camera and specialized instruments.

Advantages of VATS Thymectomy

  • Smaller incisions

  • Less pain

  • Faster recovery

  • Shorter hospital stay

  • Better cosmetic results

  • Faster return to daily activities

When Is Open Surgery Needed?

In some cases, open surgery (sternotomy or thoracotomy) may be required:

  • Large tumors

  • Tumor invasion into major structures

  • Advanced thymic carcinoma

Recovery After Surgery

  • Hospital stay: usually1 to 2  days after VATS

  • Return to normal activity: 1–3 weeks (VATS)

  • Full recovery depends on individual condition

Surgical Treatment of Myasthenia Gravis

Myasthenia gravis is an acquired autoimmune disorder that occurs when communication between nerves and muscles is disrupted by antibodies targeting neuromuscular junction receptors. This leads to progressive weakness of skeletal muscles.

The condition primarily affects muscles responsible for:

  • Eye and eyelid movement

  • Facial expressions

  • Speech

  • Chewing

  • Swallowing

Treatment Options

Treatment of myasthenia gravis typically includes:

  • Medical therapy

  • Immunosuppressive medications

These are prescribed and managed by a neurology specialist.

In addition, surgical removal of the thymus gland (thymectomy) is an important treatment option, performed by a thoracic surgeon.

Minimally Invasive Thymectomy

The surgery is performed using a minimally invasive thoracoscopic technique (VATS), without the need for opening the chest.

  • No large incision

  • Less pain

  • Faster recovery

  • Hospital stay: 24–48 hours only

Our Experience

Our surgical team, led by Dr. Mohammad Tarshihi, performs minimally invasive thymectomy for:

  • Myasthenia gravis

  • Thymic tumors

We are considered among the most experienced teams in the Arab world in thoracoscopic thymectomy, having started performing this advanced technique since 2007.

Who Is a Candidate for VATS Thymectomy?

We perform thymectomy using minimally invasive techniques in:

  • Patients with enlarged thymus in myasthenia gravis

  • Early-stage thymic tumors (Stage I and II)

Recovery After Surgery

  • Hospital stay: 24–48 hours

  • Return home shortly after discharge

  • Return to daily activities: within a few days

Will There Be Pain After Surgery?

This is a common concern.

Frequently Asked Questions (FAQ)

Is thymectomy a major surgery?

Yes, but with VATS it becomes minimally invasive and significantly safer with faster recovery.

Is VATS thymectomy safe?

Yes, it is considered a safe and standard approach when performed by an experienced thoracic surgeon.

Will I need chemotherapy after surgery?

Not always. It depends on:

  • Tumor type

  • Stage

  • Completeness of removal

How long does the surgery take?

Typically 1–3 hours, depending on complexity.

Can thymic tumors be cured?

Yes, especially when detected early and completely removed.

Does thymectomy help myasthenia gravis?

Yes, many patients experience:

  • Significant improvement

  • Reduced medication need

  • Better long-term control

What are the risks of surgery?

  • Bleeding -Rare

  • Infection-Rare

  • Lung complications
