Health Information

 

Metastatic pleural tumor

Definition

Metastatic pleural tumor is a type of cancer that has spread from another organ to the thin membrane (pleura) surrounding the lungs.

Alternative Names

Tumor - metastatic pleural

Causes

The blood and lymph systems can carry cancer cells to other organs in the body, where they can produce new growths or tumors. The spread of cancer cells to other parts of the body often occurs in patients who are dying of cancer.

Almost any type of cancer can spread to the lungs and involve the pleura.

Symptoms

Symptoms may include any of the following:

Exams and Tests

The doctor or nurse will examine you and ask about your medical history and symptoms. Tests that may be done include:

Treatment

Pleural tumors usually cannot be removed with surgery. The original (primary) cancer should be treated. Chemotherapy and radiation therapy may be appropriate, depending on the type of primary cancer.

Your health care provider may recommend thoracentesis if you have a lot of fluid collecting around your lungs and you have shortness of breath or low blood oxygen levels. This procedure removes the fluid and allows the lung to expand more, making it easier to breathe.

To prevent the fluid from collecting again, medication may be placed directly into your chest space through a tube, called a catheter. Or, your surgeon may spray a medication or talc on the lung surface during the procedure. This helps seal the space around your lungs to prevent the fluid from returning.

Support Groups

You can ease the stress of illness by joining a support group where members share common experiences and problems.

Outlook (Prognosis)

The 5-year survival rate (number of people who live for more than 5 years after diagnosis) is less than 25% for people with pleural tumors that have spread from other parts of the body.

Possible Complications


  • Side effects of chemotherapy or radiation therapy
  • Continued spread of the cancer

Prevention

Early detection and treatment of primary cancers may prevent metastatic pleural tumors in some persons.
