SCLC survival statistics & results
Click here to review statistical methodology and limitations
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 shows the cancer survival rates of 91 advanced-stage small cell lung cancer patients who were diagnosed between 2004 and 2008. All these patients were initially diagnosed at a CTCA cancer center and/or received their first treatment at CTCA.
Eighty-five percent of the CTCA patients shown in the above graph survived for six months. This means that six months after their diagnosis, nearly 85% of the patients in this group were still alive.
Lung cancer survival rates are also meaningful when compared to the results of other treatment centers. Unfortunately, most hospitals and treatment centers don’t make their lung cancer survival statistics available to the public. When they do, the results are not always consistently presented, so objective comparisons are difficult.
As an alternative, we asked the independent biostatistician to analyze and compare our survival statistics to national cancer survival statistics that are gathered by the National Cancer Institute (NCI). This database is called the NCI Surveillance, Epidemiology and End Results Program, or SEER, for short. The SEER website can be accessed at www.seer.cancer.gov or you can learn more at the NCI SEER Program page.
The chart below shows a comparison between CTCA and SEER on the survival rates of advanced-stage, small cell lung cancer patients who were diagnosed between 2000 and 2005. All 78 CTCA patients were initially diagnosed at CTCA and/or received their first treatment at CTCA.
In the above chart, the patients in both samples had advanced-stage small cell lung cancer. The patients in the SEER sample were diagnosed between 2000 and 2003, which is the most recent data available in the SEER for advanced-stage small cell lung cancer.
The green bars represent advanced-stage cancer patient survival rates from CTCA. The blue bars represent advanced-stage patient survival rates from the SEER database.
The differences in lung cancer survival rates at 6 months are statistically significant.
The differences in survival rates of lung cancer patients at 1 year and 1.5 years are not statistically significant at a 5% level.
As you study the chart, it's important to remember that the estimated CTCA survival rates were based on a relatively small sample of 78 advanced-stage small cell lung cancer patients and therefore were subject to a high degree of variation. The CTCA sample is small because only advanced-stage cancer patients who had been initially diagnosed at CTCA and/or received their first treatment at CTCA were included. This, among other factors, means that the estimates reflected in the survival chart may not be replicated in the future when a larger CTCA sample is available for comparison.
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 or the delivery of care and not all cancer patients who are treated at a CTCA hospital may experience these same results.
