SCLC survival statistics & results

How do you decide where to go for treatment after you have been diagnosed with small cell lung cancer? At Cancer Treatment Centers of America® (CTCA), we believe that knowing the survival rates of lung cancer patients who are treated at our hospitals is one of the things that can help you and your family as you make this decision. Therefore, we asked an independent, third-party biostatistician to analyze the survival results of patients who were treated at CTCA®.

The chart below reflects the CTCA and SEER survival rates for small cell lung cancer patients with distant (metastatic) disease who were diagnosed between 2000 and 2013. It includes estimates of the percentage of small cell lung cancer patients with distant (metastatic) disease who survived for six months to five years after the initial diagnosis, as recorded in the CTCA and SEER databases.

  • This analysis included small cell lung cancer patients from CTCA who had primary tumor sites (as coded by ICD-O-2 (1973+) from C340 to C343 or from C348 to C349, were diagnosed from 2000 to 2013 (including 2000 and 2013) and received at least part of their initial course of treatment at CTCA. All patients included in the analysis were considered analytic patients by CTCA.
  • Small cell lung cancer patients with distant (metastatic) disease from the SEER database and small cell lung cancer patients with distant (metastatic) disease from the CTCA database were included in the analysis. In addition, the analysis excluded patients whose medical records were missing any of the following information:
    • SEER Summary Stages
    • Primary tumor sites
    • Cancer histologic types
    • Date of initial diagnosis
    • Age at initial diagnosis
    • Gender
    • Race

*The SEER data represent national results over a large number of institutions and have been included for illustrative purposes. They are not intended to represent a controlled study and/or a perfect analysis of the CTCA data because of variability in the sample sizes of the two databases, the clinical condition(s) of the patients treated, and other factors.

The CTCA sample is relatively small because only metastatic small cell lung cancer patients who had been initially diagnosed at CTCA and/or received at least part of their initial course of treatment at CTCA were included. These factors significantly reduced the size of the CTCA sample, which means that the estimates reflected in the survival chart may be subject to high variation and may not be replicated in the future when we have a larger CTCA sample for analysis.

We also want to be sure you understand that cancer is a complex disease and each person’s medical condition is different; therefore, CTCA makes no claims about the efficacy of specific treatments, the delivery of care, nor the meaning of the CTCA and SEER analysis. Not all cancer patients who are treated at a CTCA hospital may experience these same results.
