What is an Inflammatory Myofibroblastic Tumor?

Tumors affecting the lungs and airways can arise from many different tissues. Some are common cancers, such as lung carcinoma, while others are rare conditions that develop from connective tissues or airway structures. Two such conditions are Inflammatory Myofibroblastic Tumor (IMT) and Tracheobronchial Tumors.

Though their etiology, nature, and treatment modalities vary, one cannot overlook the fact that all these tumors affect breathing and lung function. Hence, early detection and treatment are of prime importance for a good outcome and to avert any complications.

This article focuses on the causes, signs/symptoms, diagnosis, treatment options, and outlook for Inflammatory Myofibroblastic Tumors and Tracheobronchial Tumors, helping patients and caregivers better understand these conditions.

An Inflammatory Myofibroblastic Tumor (IMT) is a rare tumor that arises from myofibroblasts, cells involved in healing and tissue repair.

These tumors were previously called inflammatory pseudotumors because they resemble inflammatory masses. However, research has shown that IMTs can behave like true tumors and sometimes recur or spread.

IMTs may occur in different organs, such as:

• Lungs
• Abdomen
• Pelvis
• Liver
• Soft tissues
• Gastrointestinal tract

The lungs are among the most common sites, especially in children and young adults.

Although many IMTs are benign or slow growing, some may behave aggressively.

What are Tracheobronchial Tumors?

Tracheobronchial tumors develop in the trachea (windpipe) or bronchi, the large airways that carry air into the lungs.

These tumors are uncommon compared with typical lung cancers but can significantly affect breathing because they grow inside the airway.

Tracheobronchial tumors may be:

Benign tumors

The following are benign tumors, also known as non-cancerous growths. These tumors, which do not spread:

• Papillomas
• Hamartomas
• Adenomas

Malignant tumors

Cancerous tumors are capable of spreading.

Some common types are:

• Squamous cell carcinoma
• Adenoid cystic cancer
• Mucoepidermoid carcinoma
• Tumors that are carcinoid

These tumors block airflow, which is why symptoms often show up earlier than with other types of lung cancer.

What are the Symptoms & Causes of Inflammatory Myofibroblastic Tumor ?

Symptoms of Inflammatory Myofibroblastic Tumor

Symptoms depend on the tumor's location. When IMTs occur in the lungs, patients may experience:

• Persistent cough
• Chest pain
• Fever
• Fatigue
• Shortness of breath
• Unexplained weight loss
• Coughing up blood (rare)

Sometimes IMTs are discovered accidentally during imaging tests for unrelated conditions.

Symptoms of Tracheobronchial Tumors

Tumors growing in the airway can partially or completely block airflow.

Common symptoms include:

• Persistent cough
• Wheezing that does not improve with asthma treatment
• Shortness of breath
• Recurrent lung infections
• Chest discomfort
• Hoarseness
• Coughing up blood

Because these symptoms resemble asthma or bronchitis, diagnosis may be delayed.

Causes of Inflammatory Myofibroblastic Tumor

We still don't know what causes IMT.

However, research indicates multiple contributing factors:

• Genetic mutations, particularly rearrangements of the ALK gene
• Past infections
• Chronic inflammation
• Immune system abnormalities

Some IMTs contain abnormal genetic signaling pathways that cause uncontrolled cell growth.

Causes of Tracheobronchial Tumors

Various forms of tracheobronchial tumors have various causes.

What are the Risk Factors for Inflammatory Myofibroblastic Tumor ?

Risk factors are:

• Cigarette smoking - Using tobacco significantly increases the risk of developing airway cancers.
• Air pollution - Long-term contact with toxic airborne substances can damage the airway lining.
• Occupational exposure - Chemicals such as asbestos can pose a risk.
• Genetic predisposition - Inherited conditions can make people more vulnerable to rare airway tumors.
• Chronic airway irritation - Infection can cause tumors.

How are IMT and Tracheobronchial Tumors Diagnosed & Tested ?

Diagnosing these tumors requires imaging studies and a tissue biopsy.

Medical History & Physical Examination

Doctors start their treatment by taking a detailed medical history and performing a physical examination.

They assess the following symptoms:

• Chronic cough
• Difficulty in breathing
• Recurring respiratory infections

Listening to breath sounds may indicate airway obstruction.

Imaging Tests

Chest X-ray

A chest X-ray may indicate:

• Lung masses
• Presence of airway obstruction
• Collapsed lung segments

Small tumors may not be visible.

CT Scan

A computed tomography (CT) scan provides detailed images of the lungs and airways.

It helps doctors determine:

• Tumor size
• Exact location
• Involvement of surrounding structures
• Lymph node enlargement

CT scans are essential for planning treatment.

MRI Scan

Magnetic resonance imaging (MRI) may be used when tumors are close to major blood vessels or the spine.

MRI helps evaluate soft tissue involvement.

PET Scan

A positron emission tomography (PET) scan can identify areas of active tumor growth.

PET scans help determine whether cancer has spread to other parts of the body.

Bronchoscopy

Bronchoscopy is one of the most important diagnostic procedures for airway tumors.

During bronchoscopy:

• A thin/slim, flexible tube with a camera is inserted through the nose or mouth.
• The doctor examines the trachea and bronchi.
• Tissue samples can be collected for biopsy.

Bronchoscopy also helps determine whether the tumor is blocking the airway.

Biopsy

A biopsy confirms the diagnosis through examination under a digital microscope to establish:

• Type of tumor
• Malignant or benign status
• Presence of genetic markers like the ALK mutation

Molecular testing can help determine which target therapies to use.

What Management and Treatment Options are available for IMTs and Tracheobronchial Tumors ?

Treatment is based on various considerations, including:

• Tumor type
• Location
• Size
• Whether the tumor has spread
• Patient's overall health

Both IMTs and tracheobronchial tumors require individualized treatment plans.

Treatment for Inflammatory Myofibroblastic Tumor

Surgical Removal

Surgery is the primary treatment for most IMTs, the goal of which is to remove the tumor completely.

Common procedures include:

• Wedge resection of lung tissue
• Lobectomy (removal of a lung lobe)
• Removal of tumors in abdominal organs

Complete surgical removal usually results in excellent outcomes.

Targeted Therapy

Some IMTs have ALK gene mutations.

Patients with these mutations may benefit from ALK inhibitor-targeted drugs such as:

• Crizotinib

Targeted therapy blocks abnormal signaling pathways responsible for tumor growth.

Steroids & Anti-Inflammatory Treatment

In certain cases, IMTs may respond to medications such as:

• Corticosteroids
• Anti-inflammatory drugs

These treatments reduce inflammation and tumor size.

Radiation Therapy

Radiation therapy may be recommended when:

• The tumor cannot be completely removed.
• Surgery is not possible.

High-energy radiation destroys tumor cells.

Chemotherapy

Chemotherapy is rarely required but may be used for:

• Aggressive tumors
• Recurrent disease
• Tumors that have spread

Treatment for Tracheobronchial Tumors

Treatment for airway tumors depends on whether they are benign or malignant.

Surgery

Surgery is the best treatment for tracheobronchial tumors.

Some of the procedures used in surgery are:

• Tracheal resection - The affected portion of the trachea is surgically removed, and a new airway is created.
• Bronchial sleeve resection - The tumor-containing airway segment is removed while preserving lung tissue.
• Lung resection - In advanced cases, a lobe or the entire lung may need to be removed.

Endoscopic Tumor Removal

Some tumors can be removed through bronchoscopy using specialized techniques such as:

• Laser therapy
• Electrocautery
• Cryotherapy

These methods help reopen blocked airways.

Radiation Therapy

Radiation therapy may be used:

• After surgery
• For inoperable tumors
• To control tumor growth

It is particularly useful for certain airway cancers, such as adenoid cystic carcinoma.

Chemotherapy

Chemotherapy may be recommended when:

• The tumor has spread.
• Surgery cannot remove all cancer cells.

Chemotherapy drugs travel through the bloodstream and destroy cancer cells throughout the body.

Targeted Therapy

Some airway cancers contain specific genetic mutations that respond to targeted drugs.

Molecular testing helps identify patients who may benefit from these therapies.

Immunotherapy

Immunotherapy stimulates/instigate the immune system to attack cancer cells.

These drugs are increasingly used in advanced lung cancers.

What are the Possible Complications for Inflammatory Myofibroblastic Tumors and Tracheobronchial Tumors ?

Both inflammatory myofibroblastic tumors and tracheobronchial tumors may lead to complications if not treated early.

Potential complications include:

• Airway obstruction
• Lung collapse
• Recurrent pneumonia
• Bleeding in the airway
• Spread of cancer to other organs

Early diagnosis significantly reduces the risk of severe complications.

What is Outlook / Prognosis for Inflammatory Myofibroblastic Tumors and Tracheobronchial Tumors ?

The prognosis varies depending on tumor type, stage, and treatment success.

Prognosis of Inflammatory Myofibroblastic Tumor

Most IMTs have a favorable prognosis, especially when completely removed through surgery.

Important factors affecting prognosis include:

• Tumor location
• Completeness of surgical removal
• Presence of genetic mutations

There is a recurrence in some cases. Therefore, long-term follow-up is necessary.

Prognosis of Tracheobronchial Tumors

The prognosis of tracheobronchial tumors depends on:

• Type of tumor
• Stage of tumor
• Response to Treatment

The prognosis of benign tumors is good if they are successfully removed.

The prognosis of malignant tumors is dependent on early detection. In this case, several forms of treatment may be applied.

How do Patients Live with Inflammatory Myofibroblastic Tumors and Tracheobronchial Tumors ?

Patients who are diagnosed with airway tumors need follow-up care for a long period of time.

Some of the recommendations that a patient may need include:

• Regular CT scans
• Bronchoscopy examinations
• Lung function tests

Such examinations may help detect recurrence early.

Patients may recover well by adopting healthy lifestyle habits, such as quitting smoking, maintaining lung health, and avoiding environmental pollutants.

What should be the Prevention Strategies for Inflammatory Myofibroblastic Tumors and Tracheobronchial Tumors ?

Although not all tumors can be prevented, the following can be done to help prevent tumors:

• Avoid tobacco smoking.
• Avoid exposure to harmful chemicals.
• Use protective gear if you work in a hazardous job.
• Consult a doctor if you experience respiratory problems.

Health check-ups can also help detect abnormalities.

When Should You Consult to doctor for Inflammatory Myofibroblastic Tumors and Tracheobronchial Tumors ?

The following are when you should consult a doctor:

• Persistent cough lasting more than three weeks
• Unexplained breathing difficulty
• Repeated lung infections
• Chest pain or coughing up blood

Early evaluation allows prompt diagnosis and treatment.
