Serum levels of tumor markers generally increase along with the increase of tumor size, and most HCCs at some stages are associated with the increase of PIVKA-II in the serum. A document is time series data of measured value of tumor size and serum PIVKA-II level of the patient that HCC was found. The various attempted to model tumor growth and tumor marker increase during the treatment time interval as well as during its unperturbed state have been variations of density-limited kinetic equations. The exponential and logistic equations were popular models currently being employed to describe growth kinetics giving the time behavior of intrinsic tumor growth and its dose-response curve. All that had to be done was the plotting of the fitted exponential or logistic on the plot containing the time and serum PIVKA-II level data or tumor size data. The results emphasized the remarkable predictive ability of the model during an extended period of time in which the modest assumptions of the models were at least approximately true., 10, KJ00000097930}, pages = {69--74}, title = {肝細胞癌における腫瘍径とPIVKA-IIの解析学的検討}, volume = {24}, year = {2003}, yomi = {カタヤマ, トシロウ and ババ, シゲアキ} }
