Signs: When to Think Thymoma
Thymomas are usually not detected until they are quite large or accidentally found on imaging studies done for other reasons. Any pressure signs (from size):
– Chest pain or tightness
– Cough
– Shortness of breath
– Hoarseness of voice
– Difficulty swallowing (dysphagia)
– Swelling of face or neck (due to superior vena cava obstruction)
Constitutional:
– Weakness of muscle, particularly high in the body (around the eyes), or high or low in the limbs (suggestive of myasthenia gravis)
– Fatigue
– Anemia / infections (if whole immune system is impaired)
If, in doubt, you should seek evaluation with a thoracic specialist if any of these symptoms persist or worsen.
Diagnosis: How Is Thymoma Diagnosed?
1. Studies
– Thymomas can be found on a chest x-ray as opacity in the mediastinum
– CT Scan (chest) is the gold standard and provides the most data regarding size, invasion, and anatomy in regard to local structures
– MRI or PET-CT can also be done for more data or to just stage the cancer
2. Lab work
– Can be autoimmune markers (e.g. anti-acetylcholine receptor antibodies for myasthenia)
– Regular blood counts and immunoglobulin too
3. Biopsy (sometimes)
– Possibly unnecessary, if proved mathematically to be resectable
– For biopsy, usually with a CT.
Staging and Classification
The Masaoka-Koga system is the most commonly used to describe extent of disease:
• Stage I: tumor is completely encapsulated with no invasion.
• Stage II: tumor has invaded local fat or pleura.
• Stage III: tumor has invaded an adjacent organ (pericardium, lung, major vascular structures).
• Stage IV: tumor has spread to other places (pleura, lymph nodes, or distant organs).
Masaoka-Koga system is not the only thing to consider. Thymomas are also categorized by histology (WHO classification: Types A, AB, B1–B3, and C), which is important for treatment and disposition.
When do we recommend surgery?
Surgical resection is the cornerstone of therapy for nearly every thymoma, especially the early-stage tumors. The aim is complete, margin-negative resection.
Surgery is suggested for:
• Thymoma confirmed/suspected on imaging
• Tumors with causing symptoms of pressure
• Autoimmune conditions like myasthenia gravis that are associated
• Recurrent/residual disease after other treatments
It is critical to consult a thoracic surgeon to evaluate operability, the optimal surgical approach, and safely handle intraoperative situations.
Surgical Approaches: Minimally Invasive to Open
1. Minimally Invasive Surgery
• VATS (Video-Assisted Thoracoscopic Surgery) or
• RATS (Robotic-Assisted Thoracic Surgery)
Best for small, early-stage thymomas that don’t invade any adjacent organs.
Advantage: They are less painful, smaller incision, shorter hospital stay, and quicker return to normal activity than traditional surgery.
2. Open Surgery (Median Sternotomy)
Indicated when:
• Large or invasive tumor
• Involvement of vessels or heart
• Resection can’t be performed with minimally invasive techniques.
Surgery Risks and Complications
Surgery is relatively safe, but there is always a risk for:
• Bleeding
• Infection
• Damage to surrounding structures (lungs, heart, major vessels)
• Persistent myasthenia symptoms (in autoimmune associated thymoma)
• Postoperative respiratory complications
Selecting an experienced thoracic surgeon such as Dr. Kamran Ali, significantly reduces these risk factors.
What Happens After Surgery?
1. Recovery
• Hospital stay: 2–5 days (if open surgery, potentially longer)
• Returning to work: 2–4 weeks (depending on surgical method and patient health)
• Working on pain management, performing breathing exercises and physical activity are vital during recovery.
2. Pathology Report
• Provides confirmation of the diagnosis
• Reports on margins, histological subtype, and level of invasion
• Indicates if further treatment is necessary
Do All Patients Get Chemotherapy or Radiation?
Not necessarily.
Post-operative Radiation Therapy (PORT):
• Recommended often in Stage II/III thymomas or incomplete resections
• Decreases risk of recurrence
Chemotherapy:
• Used for unresectable, advanced (Stage IV), or recurrent disease
• Chemotherapy is often cisplatin-based protocol These treatments are often provided in coordination with an oncologist and radiation specialist — forming part of a multidisciplinary care team.
Long-Term Follow-Up and Outlook
Patients who have undergone complete resection of thymomas generally do extremely well, particularly when they are diagnosed at earlier stages of thymoma. Prognosis:
• Stage I–II: Excellent prognosis (90% 5-year survival)
• Stage III: Reasonable prognosis with complete resection and adjuvant treatment
• Stage IV: Prognosis varies; patients will likely require long-term systemic treatment
Follow-Up Care:
• CT scans every 6–12 months (with initial follow-up scans)
• Monitor for recurrent symptoms or new symptoms
• Neurological assessment should continue if the patient has Myasthenia
Living with Thymoma: Patient recommendations
• Do not ignore mild or unusual chest symptoms. Early diagnosis will achieve better outcomes.
• If you have a thymoma, get a thoracic surgical opinion early, regardless of whether you are symptomatic.
• If you have an autoimmune medical condition (e.g., Myasthenia Gravis), make sure your surgical team is aware of this condition and has sufficient experience managing similar cases.
• Be active in your care – ask questions, discuss all treatment options, and clarify personal and medical goals of surgery and follow-up.

Conclusion
The diagnosis of thymoma tends to be rare. However, thymoma is very treatable with excellent thoracic surgical expertise – especially if detected early. If you, or someone you know, have been diagnosed with a mediastinal tumor or are having unexplained chest complaints, see a thoracic surgery consultant who can iosenuate.
Your chest houses some very important organs – so make sure it is being treated by a surgeon who truly understands the anatomy.
If you would like to discuss your case for a consultation or seek a second opinion, please contact Dr. Kamran Ali – Thoracic Surgeon. Your chest deserves the best.
