2. Lung Cancer
Lung cancer – uncontrollable growth of abnormal cells in the lung(s) form masses of tissue or tumors
Malignant
can spread to nearby tissues or other organs
2 main types
-Non-Small Cell Lung Cancer
-Small Cell Lung Cancer
In , 974 people were
diagnosed with lung cancer
-158, 081 people died from lung cancer

3. Lung Cancer Non-Small Cell Lung Cancer is most common
Accounts for ~85% of all diagnoses
Four stages:
Stage 1: cancer is localized to lungs
Stage 2: cancer has spread to nearby lymph nodes
Stage 3: cancer has spread to lymph nodes in the middle of the chest
Stage 4: advanced disease; cancer has spread to both lungs, fluid around the lungs, and/or to other tissues and organs
Small Cell Lung Cancer
2 stages:
Limited: cancer in one part of a single lung plus nearby lymph nodes
Extensive: cancer has spread throughout the chest, other tissues, and organs

4. Symptoms Damage to the lungs and surrounding tissues/structures
Persistent and/or worsening cough
Coughing up blood
Wheezing or shortness of breath
Chronic pneumonia or bronchitis
Chest pain
Fatigue

5. Risk Factors Smoking ( #1 cause) or second hand smoke
Tuberculosis or other lung diseases
Environmental exposure to carcinogens
such as asbestos, diesel exhaust, and radon
Age
Family history

6. Treatment Surgery – remove lobe/section of lung with tumor
Chemotherapy – drugs are used to shrink or kill the cancer
Carboplatin, Cisplatin
Radiation
Targeted drug therapy – drugs specifically target cancer cells
Tarceva, Avastin, Xalkori

7. Airway Stents

8. Types of Stents EGIS Airway Stent drawstring for easy removal
polishing process removes micro cracks
non-biodegradable silicone membrane
Nitinol for shape memory and superelasticity
barbs prevent migration
available in a variety of types and sizes (diameters and lengths)

9. What makes it the best choice?
Use stent after chemotherapy and radiation treatment fail to remove blockage.
Helps patients undergoing mechanical ventilation to breath unassisted.
Restore collapsed
airway.
rapid relief
for symptoms

10. Costs Surgery costs $5000 Individual stents can be $1000-2000.
Median cost of removal surgery is $10,700.

11. Implantation Protocols
Sedation and bronchoscopy
Insert guidewire and sizing catheter to measure size of obstruction.
Insert breathing tube to allow airflow during insertion.
Deploy stent.
Secure stent placement.

13. Recovery and Patient Followup
Symptoms improve in 84%
of patients within 24 hours
Bronchoscopy check ups.
Monitor for coughing,
shortness of breath, etc.
Doesn’t require
immunosupressants
Long term complications
can require additional surgery

14. Complications Migration of stent. Trouble breathing. Bleeding.
Pneumonia or other infection.
New airway obstruction from accumulated secretions or tumor growth.
Stent fracturing.

15. Conclusion
EGIS airway stent provides rapid relief of symptoms and drastically improves quality of life for patients.
Provides time for chemotherapy or drugs to take effect, or for conditions to improve and allow for surgery.
Despite potential complications, airway stents have proven to be versatile and effective.
