|Abstract:||Mortality or survival rate is a criterion for measuring the prognosis of cancer patients. A uniform method should be used for the calculation of survival rate for the purpose of comparing effectiveness of cancer treatments. Life table method is the most suitable way to evaluate a survival rate of all cases in the series. The actuarial survival rate is completed only after computation of the relative survival rate. Other words the relative survival rate is the only useful value on the life table method. Only a few Japanese reporters have presented the relative survival rate in their papers for cancer therapy. Expected survival rate is provided from life table for Japan. One to five years survival probability for Japanese was discribed. These tables will contribute many reporters intending to report their own experiences for cancer therapy. Each data of cancer therapy can be estimated under the same methodology of computing survival rate and controlled background of patients. The prognosis of patient with cancer is regard to depend on the staging of the own desease. Therefore the survival rate should be caluculated according to stage or grade of the cancer. Also we should care that the survival rate is not valuable if the alived cases are less than ten.|
