Background: Some cancer survivors develop second primary cancers. However, differences in prognosis between patients who have and have not had prior cancer have not been established. We examined and compared the prognoses of such patients.Methods: Using the record-linked database of the population-based Cancer Registry of Osaka Prefecture and Vital Statistics in Japan, we identified patients aged >= 40 years who were diagnosed with stomach (n = 70,946), colorectal (n = 60,582), or lung (n = 58,016) cancers during 1995-2009. We defined these cancers as index cancers. Patients were classified into three groups according to history of prior cancer and interval between diagnosis of index and prior cancer: single (no prior cancer or interval of >= 10 years), synchronous (interval
