concepts of this type of analyses and the characteristics of survival times were presented. Aspects related with the different methods facilitating the estimation of survival probabilities for one or more groups of subjects, including the example of calculation of Kaplan Meier method´s probabilities were dealt with . The survival rates of several groups were compared, taking into consideration various factors that differentiate them. Some of the statistical tests making the comparison possible such as log rank test, and the Breslow test as an alternative of the former when there is a proportional random divergence, that is, when survival curves cross were stated
