[Observations on the growth rate of polypoid type gastric cancers with doubling times based on a retrospective roentgenological study].
For the purpose of estimating the growth rate, 11 cases of polypoid type gastric cancer have been studied. The mean doubling time was found to be 16.6 months in early cases, and 7.6 months in advanced cases. There were two groups with different growth rates in polypoid type gastric cancer. However, from a study of a case growing faster according to the extension of tumor, it is suggested that the difference of the growth rate between the two groups may have resulted from a discrepancy of when the observation began.
