At Cancer Treatment Centers of America^®(CTCA), we understand that you may want to see information regarding the survival results of patients with distant (also referred to as metastatic) stomach cancer who werediagnosedand/or at least initially partly treated at our hospitals to help you and your family decide where to go fortreatment,as part of many other factors you may be considering. Therefore, we asked an independent biostatistician to analyze thesurvival resultsof CTCA^®patients.

Statistical methodology and limitations
Qualifications of the independent researchers

The chart below reflects the CTCA and SEER survival rates for stomach cancer patients with distant (metastatic) disease who were diagnosed between 2000 and 2015. It includes estimates of the percentage of stomach 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 includedstomach cancerpatients from CTCA who had primary tumor sites (as coded by ICD-O-2 (1973+) of C160 to C169, were diagnosed from 2000 to 2015 (including 2000 and 2015) 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.
• Stomach cancer patients with distant (metastatic) disease from the SEER database and stomach 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 CTCA sample is relatively small because only metastatic stomach 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 analyses. Not all cancer patients who are treated at a CTCA hospital may experience these same results.
