Targeted Therapy

Your doctor may refer you to a specialist who has experience treating lung cancer, or you may ask for a referral. You may have a team of specialists. Specialists who treat lung cancer include thoracic (chest) surgeons, thoracic surgical oncologists, medical oncologists, and radiation oncologists. Your health care team may also include a pulmonologist (a lung specialist), a respiratory therapist, an oncology nurse, and a registered dietitian.

Lung cancer is hard to control with current treatments. For that reason, many doctors encourage patients with this disease to consider taking part in a clinical trial. Clinical trials are an important option for people with all stages of lung cancer. See "The Promise of Cancer Research."

The choice of treatment depends mainly on the type of lung cancer and its stage. People with lung cancer may have surgery, chemotherapy, radiation therapy, targeted therapy, or a combination of treatments.

People with limited stage small cell lung cancer usually have radiation therapy and chemotherapy. For a very small lung tumor, a person may have surgery and chemotherapy. Most people with extensive stage small cell lung cancer are treated with chemotherapy only.

People with non-small cell lung cancer may have surgery, chemotherapy, radiation therapy, or a combination of treatments. The treatment choices are different for each stage. Some people with advanced cancer receive targeted therapy.

Cancer treatment is either local therapy or systemic therapy:

• Local therapy: Surgery and radiation therapy are local therapies. They remove or destroy cancer in the chest. When lung cancer has spread to other parts of the body, local therapy may be used to control the disease in those specific areas. For example, lung cancer that spreads to the brain may be controlled with radiation therapy to the head.
  
  
• Systemic therapy: Chemotherapy and targeted therapy are systemic therapies. The drugs enter the bloodstream and destroy or control cancer throughout the body.

Your doctor can describe your treatment choices and the expected results. You may want to know about side effects and how treatment may change your normal activities. Because cancer treatments often damage healthy cells and tissues, side effects are common. Side effects depend mainly on the type and extent of the treatment. Side effects may not be the same for each person, and they may change from one treatment session to the next. Before treatment starts, your health care team will explain possible side effects and suggest ways to help you manage them.

You and your doctor can work together to develop a treatment plan that meets your medical and personal needs.

Surgery

Surgery for lung cancer removes the tissue that contains the tumor. The surgeon also removes nearby lymph nodes.

The surgeon removes part or all of the lung:

• A small part of the lung (wedge resection or segmentectomy): The surgeon removes the tumor and a small part of the lung.
• A lobe of the lung (lobectomy or sleeve lobectomy): The surgeon removes a lobe of the lung. This is the most common surgery for lung cancer.
• All of the lung (pneumonectomy): The surgeon removes the entire lung.

After lung surgery, air and fluid collect in the chest. A chest tube allows the fluid to drain. Also, a nurse or respiratory therapist will teach you coughing and breathing exercises. You'll need to do the exercises several times a day.

The time it takes to heal after surgery is different for everyone. Your hospital stay may be a week or longer. It may be several weeks before you return to normal activities.

Medicine can help control your pain after surgery. Before surgery, you should discuss the plan for pain relief with your doctor or nurse. After surgery, your doctor can adjust the plan if you need more pain relief.

Radiation Therapy

Radiation therapy (also called radiotherapy) uses high-energy rays to kill cancer cells. It affects cells only in the treated area.

You may receive external radiation. This is the most common type of radiation therapy for lung cancer. The radiation comes from a large machine outside your body. Most people go to a hospital or clinic for treatment. Treatments are usually 5 days a week for several weeks.

Another type of radiation therapy is internal radiation (brachytherapy). Internal radiation is seldom used for people with lung cancer. The radiation comes from a seed, wire, or another device put inside your body.

The side effects depend mainly on the type of radiation therapy, the dose of radiation, and the part of your body that is treated. External radiation therapy to the chest may harm the esophagus, causing problems with swallowing. You may also feel very tired. In addition, your skin in the treated area may become red, dry, and tender. After internal radiation therapy, a person may cough up small amounts of blood.

Your doctor can suggest ways to ease these problems. You may find it helpful to read NCI's booklet Radiation Therapy and You.

Chemotherapy

Chemotherapy uses anticancer drugs to kill cancer cells. The drugs enter the bloodstream and can affect cancer cells all over the body.

Usually, more than one drug is given. Anticancer drugs for lung cancer are usually given through a vein (intravenous). Some anticancer drugs can be taken by mouth.

Chemotherapy is given in cycles. You have a rest period after each treatment period. The length of the rest period and the number of cycles depend on the anticancer drugs used.

You may have your treatment in a clinic, at the doctor's office, or at home. Some people may need to stay in the hospital for treatment.

The side effects depend mainly on which drugs are given and how much. The drugs can harm normal cells that divide rapidly:

• Blood cells: When chemotherapy lowers your levels of healthy blood cells, you're more likely to get infections, bruise or bleed easily, and feel very weak and tired. Your health care team gives you blood tests to check for low levels of blood cells. If the levels are low, there are medicines that can help your body make new blood cells.
  
  
• Cells in hair roots: Chemotherapy may cause hair loss. Your hair will grow back after treatment ends, but it may be somewhat different in color and texture.
  
  
• Cells that line the digestive tract: Chemotherapy can cause poor appetite, nausea and vomiting, diarrhea, or mouth and lip sores. Ask your health care team about treatments that help with these problems.

Some drugs for lung cancer can cause hearing loss, joint pain, and tingling or numbness in your hands and feet. These side effects usually go away after treatment ends.

When radiation therapy and chemotherapy are given at the same time, the side effects may be worse.

Targeted Therapy

Targeted therapy uses drugs to block the growth and spread of cancer cells. The drugs enter the bloodstream and can affect cancer cells all over the body. Some people with non-small cell lung cancer that has spread receive targeted therapy.

There are two kinds of targeted therapy for lung cancer:

• One kind is given through a vein (intravenous) at the doctor's office, hospital, or clinic. It's given at the same time as chemotherapy. The side effects may include bleeding, coughing up blood, a rash, high blood pressure, abdominal pain, vomiting, or diarrhea.
  
  
• Another kind of targeted therapy is taken by mouth. It isn't given with chemotherapy. The side effects may include rash, diarrhea, and shortness of breath.

During treatment, your health care team will watch for signs of problems. Side effects usually go away after treatment ends.

You may find it helpful to read the NCI fact sheet Targeted Cancer Therapies. It tells about the types of targeted therapies and how they work.
