Lung Cancer

Stages of Lung Cancer

The stages will depend on the type of lung cancer. Some stages will have substages to reflect how advanced the cancer is within that stage and depends on the size of the tumor, where the tumor is located, and whether or not the cancer has spread to other parts of the body.  

Non-small cell lung cancer stages (NSCLC)

Stage 0: Early stage of lung cancer that has only impacted the top lining of the lung or bronchus and has not spread to other areas in the body.

Stage I: This stage is divided into two substages based on the size of the tumor: IA and IB. The cancer has not spread to the lymph nodes or other parts of the body.

Stage II: This stage is also divided into two substages IIA and IIB. At this phase, the tumors have begun to spread to nearby lymph nodes, but have not yet impacted distant organs.  

Stage III: Stage III is divided into IIIA, IIIB, or IIIC. Cancer at this point has spread to the lymph nodes between the lungs.

Stage IV: This is the most advanced form of NSCLC. The cancer has spread to the lining of the lung or other areas of the body.

Small cell lung cancer stages (SCLC)

• Limited is cancer present in only one lung with or without spread to the lymph nodes in the area between the lungs.
• Extensive means the cancer had spread to the tissue outside of the originally affected lung like the opposite lung or distant organs.

Treatments for Lung Cancer

Our lung cancer specialists follow ground-breaking research and the latest treatment guidelines to deliver comprehensive cancer care. They will work with you to discuss your diagnosis, explore treatment options, and help you plan while keeping your priorities and preferences top of mind.  

Lung cancer treatment will vary from patient to patient and will depend on one’s age, medical history, type of lung cancer, extent of the disease, and your tolerance for certain procedures. Below, you will find some common treatments.  

Surgery

Surgery is an option for patients with early-stage lung cancer. The type of surgery will largely depend on the size and location of the tumor, the patient’s overall health, and other factors. Some surgeries include:

• Segmental or wedge resection: A removal of a small part of the lung  
• Lobectomy: Removal of an entire lobe of the lung  
• Pneumonectomy: Removal of the entire lung  
• Sleeve resection: Removal of a piece of bronchus  

Radiation therapy

Using high-energy radiation, radiation therapy shrinks tumors and kills cancer cells. There are two techniques used to deliver radiation therapy: 

• External radiation: Sends high levels of radiation directly to the cancer cells while protecting the surrounding tissue
• Proton therapy: Focuses energy on the tumor with less radiation exposure to the surrounding healthy tissue 

Chemotherapy

Chemotherapy is administered through an IV and delivered to the entire body to shrink and kill cancer cells.

Immunotherapy 

Immunotherapy utilizes drugs, vaccines, and other therapies to activate the body’s natural defenders to fight cancer. Currently, only three immunotherapy drugs have been approved for NSCLCs: pembrolizumab, atezolizumab, and nivolumab.  

Radiation oncologists use targeted radiation therapy to destroy cancer cells while preserving surrounding healthy tissue. After surgery, a radiation oncologist may deliver targeted radiation to lymph nodes where cancer cells may have spread.
