Cancer staging and survival rates: an analysis.
The interrelation between tumor staging and survival is an inverse one; patients with more widespread disease tend to have a shorter survival. Using this as a basis, a relationship was given between the logarithm of the percent survival at five years and the tumor stage at diagnosis. The description yielded an excellent fit for six reported neoplasms. For four other malignancies, the curves revealed a shape which resembled that of a multitarget model. The simpler description of logarithm of survival versus stage could be viewed as the limiting value of a multitarget model when the target number equals 1.
