Stage 2 Non-Small Cell Lung Cancer

Stage 2 non-small cell lung cancer (NSCLC) is defined as a localized cancer, which means the tumor has not spread beyond one lung or the local lymph nodes. When the cancer spreads to distant lymph nodes or other parts of the body, it's considered advanced lung cancer.

If you've been diagnosed with stage 2 lung cancer, you're in a good position to begin treatment. While lung cancer's overall survival rate is not very good, that's partly because only about 16% of NSCLC is diagnosed in the localized stages (stage 1 or stage 2). When it is caught at an early stage, lung cancer is very treatable, and your chances for a long-term remission are good.

Staging

Determining the stage of a lung cancer is very important in choosing the most appropriate treatment.

Oncologists talk about stages of lung cancer based on something called the TNM system. In this system, T refers to the size of the tumor, N refers to the involvement of any lymph nodes and where they are located, and M indicates if there are any metastases, spreading of the tumor to other regions of the body.

Stage 2 is divided into stages 2A and 2B. Stage 2B is divided into three possible designations.

Symptoms

In early stages of lung cancer, you may have no symptoms. As the disease progresses, though, common stage 2 lung cancer symptoms may arise. These include:

• Persistent cough
• Coughing up blood
• Shortness of breath
• Hoarseness
• Pain in the chest or back
• Repeated infections such as pneumonia or bronchitis

Since stage 2 lung cancer has not metastasized beyond the lungs, symptoms such as unintentional weight loss and fatigue are less common than in more advanced stages.

The symptoms of lung cancer in women may differ from men, and symptoms in non-smokers may differ from current or former smokers. This is important to consider as cases of lung cancer have been increasing among young women who have never smoked, many of whom assume they are not at risk for the disease and miss early signs of a problem.

Treatment

Treatment options for stage 2 lung cancer most often include a combination of therapies.

Surgery

The greatest hope for long-term survival after your diagnosis is surgery There are 4 main types of surgery available for lung cancer:

• Pneumonectomy: The entire lung is removed. This is usually only recommended if the tumor’s location prevents less invasive surgeries.
• Lobectomy: This removes one of the five lobes that make up your lungs (3 on the right, 2 on the left). This surgery is often preferred for NSCLC.
• Wedge resection: A wedge-shaped section of a lobe is removed. This is usually recommended if the tumor is small or there is a concern about lung function.
• Sleeve resection: This removes part of the lung and a part of the main airway. It may preserve more lung function than other types of surgeries.

Which procedure you choose depends on where your tumor is located and your general state of health.



Chemotherapy

Most oncologists recommend adjuvant chemotherapy (chemotherapy after surgery) for those who undergo surgery for stage 2 lung cancer. The advantage of this type of chemotherapy is that it "cleans up" any cancer cells that may have spread beyond the lungs but are not yet visible on any imaging tests. Depending on the location of your tumor, some oncologists may instead use neoadjuvant chemotherapy—chemotherapy given before surgery to decrease the size of a tumor and make removing the tumor easier.

Radiation Therapy for Inoperable Tumors

Radiation therapy is not often used with stage 2 lung cancer but is an option for those who are unable to have surgery due to the tumor's location or general health concerns. Other techniques such as proton beam therapy are being evaluated for stage 2 disease.

Genetic Targeting

One of the recent advances in lung cancer treatment has been the ability to treat some of these cancers by "targeting" mutations in the tumor. Along with characterizing a tumor based on size and how far it has spread, oncologists are now using genetic testing (molecular profiling) of lung cancer to personalize the diagnosis and treatment. Previously, testing was reserved primarily for people with more advanced stages of the disease, but with advances in treatment, it's likely that for those with stage 2 NSCLC, especially people with lung adenocarcinoma, this testing will become routine.

Prognosis

The five-year survival rate for stage 2 NSCLC is approximately 35% with treatment. Of course, this varies depending upon your particular tumor and your general health. Keep in mind that statistics about survival are often several years old, and new treatments that have been approved may not have been available when those numbers were recorded.

The key to improving your chances of having lung cancer go into long-term remission is getting the appropriate treatment. So discuss all your options with your doctor and be hopeful. Treatments are improving every day.

Risk of Recurrence

The overall lung cancer recurrence rate for stage 2 NSCLC is estated to be about 38%. If a lung cancer recurs, further options are available for treatment. These may include radiation with or without chemotherapy, targeted therapies, or immunotherapy medications.

Coping

Studies suggest that learning about your disease can improve your outcome. Ask questions. Learn about clinical trials that might be appropriate for you. If you are newly diagnosed with lung cancer, take a moment to breathe and think carefully about your current situation.

This is a time to allow others to help you and look into support groups in your community as well as online where you can connect with people who understand and have advice to offer. Remember, too, there are some things you can do yourself that improve survival with lung cancer.

A Word From Verywell

Both the treatments for, and survival rates from, lung cancer are improving rapidly. While this is wonderful, it can be hard for any general oncologist to stay abreast of the latest improvements in all areas of care, and it's important to learn how to advocate for yourself as a cancer patient
