When is chemotherapy used NSCLC?
Chemotherapy
Chemotherapy (chemo) is a treatment used to stop the growth of cancer cells. It may be injected into a vein or taken by mouth. These drugs travel through the bloodstream and reach most parts of the body. Most chemo drugs used for lung cancer are given into a vein (IV), either as an injection over a few minutes or as an infusion over a longer period of time (Figure 1). Depending on the drug(s), it may be given in a doctor’s office, chemotherapy clinic, or in a hospital setting. Chemo may be used with radiation therapy, with surgery, and/or with other types of drugs (for example, target therapy or an immune checkpoint inhibitor [sometimes called immunotherapy]).
Types of chemotherapy used for NSCLC
The chemo drugs most often used for NSCLC include:
- Cisplatin
- Carboplatin
- Paclitaxel (Taxol®)
- Albumin-bound paclitaxel (Abraxane®)
- Docetaxel (Taxotere®)
- Gemcitabine (Gemzar®)
- Vinorelbine (Navelbine®)
- Etoposide (VP-16)
- Pemetrexed (Alimta®)
Most patients will receive cisplatin or carboplatin with another chemo drug. The drugs used depend on several things, including the type of lung cancer you have. For example, patients with non-squamous NSCLC often receive pemetrexed, while patients with squamous NSCLC often receive paclitaxel.
Chemo for early-stage NSCLC
For certain early-stage NSCLC tumors, chemo may be used before or after surgery. Neoadjuvant chemo is used before surgery (sometimes with radiation therapy). Adjuvant chemo is used after surgery (sometimes with radiation therapy) to try to kill any cancer cells that might have been left behind. Your doctor will tell you about the timing of your chemo.
Doctors give chemo in cycles that usually include a treatment period plus a rest period. Most cycles are 3 or 4 weeks long. Your doctor will let you know the number of cycles you will get. They may offer you more than one option to choose from.
Adjuvant or neoadjuvant chemo is often given for 3 to 4 months, depending on the drugs used.
Usually, two chemo drugs are used to treat early-stage lung cancer. Cisplatin or carboplatin is often used with pemetrexed or paclitaxel. Gemcitabine with vinorelbine or paclitaxel are other combinations sometimes used. Many patients receive an immune checkpoint inhibitor with the chemo. Examples of drug combinations used for early-stage NSCLC are shown in Table 1.
Chemo for advanced NSCLC
Advanced lung cancer is also called stage IV or metastatic cancer. It means that the cancer has spread to places in your body outside of the lungs. Advanced lung cancer may be treated with a single drug, especially for people who might not tolerate more than one drug well, such as those in poor overall health.
For some people with advanced lung cancer, a targeted therapy or an immunotherapy drug may be given along with chemotherapy.
For advanced cancer, the initial chemo combination is often given for four to six cycles. Some doctors now recommend giving treatment beyond this with a single drug, for people who’s tumor has gotten smaller or has not grown. This is called maintenance therapy. It helps to keep the cancer from growing.
If the first chemo drug (or drugs) do not work or stop working, your doctor may talk to you about using different medicine.
