Abstract
We know that we can measure the cancer patient's cellular immunity by the PPD. The ratio of the PPD negative patients increase relatively to the advancement of the stage of the cancer. As the prognosis of the PPD negative group is worse than that of PPD positive group in the same stage, we must consider the patients prognosis not only from the stage of the disease but also the view-point of the PPD reaction. The lymphocytes as well as T-cell decrease in number when the cellular immunity becomes poor in condition. conse-quently we may use them as the assistant parameter of the PPD test.
We believe that by the use of the therapy which changes PPD reaction from negative to positive and maintain this condition will prolong the patients life. Either the removal of the tumor or chemotherapy(i. A. ) improved the cellular immunity of the patients.
The PPD negative patients who are inoperable group in the stomach cancer stage-IV can not be treated effectively with unspecified-immunotherapy without the use of the chemotherapy(i.A.).
The timing methode in the cancer immunochemotherapy seems to be needed the PPD reaction as the index of the treatment point.
