Mortality trends in carcinoma of the cervix uteri.

REVIEW of the cancer deaths among 1202 staged cases of carcinoma of the cervix treated at the Radiation Therapy Center of the University of Michigan from 1941 through 1964 indicates that each clinical stage is endowed with its own singular mortality trend. The cancer mortality trend of each stage is in our experience independent of the 5-yr survival rate. Improved survival obtained through the use of more effective therapeutic methods has not altered the mortality trend of each stage. We have also obtained evidence that when the logarithm of survival time of the patients destined to die of cancer is plotted against time the line of regression is straight. These observations are based on examination of the following case material.
