Treatment
Journey

Small cell lung cancer (SCLC) grows quickly, so treatment usually starts soon after diagnosis. Your treatment plan will be shaped by the stage of your SCLC and your overall health.1,2 It's a lot to process, and it's okay to lean on your care team and loved ones for support.

Treatment for limited-stage SCLC

For limited-stage (LS) SCLC, treatment typically includes chemotherapy and radiation therapy given together (called concurrent chemoradiation), which may be followed by immunotherapy. This combination approach is the standard of care for LS-SCLC.3

  • If SCLC is found very early and is limited to a single small tumor, surgery may be an option, usually followed by chemotherapy2,3
  • After initial treatment, prophylactic cranial irradiation (PCI) may be recommended to help prevent the cancer from spreading to the brain2

Treatment for extensive-stage SCLC

Initial treatments

First course of therapy

The standard first treatment for extensive-stage (ES) SCLC is a combination of platinum-based chemotherapy plus immunotherapy, typically given for 4 cycles, with each cycle lasting about 3 weeks.2,4,5

Continuing with maintenance therapy

After completing the first course of therapy, treatment may continue with maintenance therapy—ongoing treatment designed to help keep the cancer under control. Maintenance therapy may involve a combination of immunotherapy and chemotherapy.4,6

Subsequent treatment

If SCLC comes back (recurs) or continues to grow during or after treatment, additional treatment options may be available. This can include another course of the same chemotherapy or medicines that attack cancer cells in different ways. The choice of subsequent therapy depends on several factors, including how long it has been since your last treatment and your overall health. Your doctor can discuss options for subsequent treatment and what may be right for your situation.2,3

Planning ahead matters

Ask your doctor about setting up a plan from the start for both your first course of therapy and maintenance therapy.
