The work goal is to evaluate the relationship between overall survival time and disease-free time through copula functions, considering marginal Weibull survival distributions. The clinical stage of patients and DNA ploidia are considered statistically relevant for both survival times. Regarding the age of patients, its effect is only relevant to the overall survival time of older patients. The risk of a recurrence of cancer or death, given the clinical characteristics of the patient, is different for the univariate and bivariate models. In addition, the estimation of the copulation parameter demonstrates a high association between the times under study. This is a joint work with Beatriz Lourenço. </font><br style="margin: 0px; padding: 0px; list-style: none; vertical-align: baseline;" class=""><br style="margin: 0px; padding: 0px; list-style: none; vertical-align: baseline;" class=""><span style="font-size: 14px;" class=""><strong style="font-family: Roboto, sans-serif; margin: 0px; padding: 0px; list-style: none; vertical-align: baseline;" class="">Bio:</strong><br style="margin: 0px; padding: 0px; list-style: none; vertical-align: baseline;" class=""><font face="Roboto, sans-serif" class="">Giovani Loiola da Silva is Assistant Professor at the Department of Mathematics at Instituto Superior Técnico (IST) and member of the Center for Statistics and Applications (CEAUL), both at the University of Lisbon.
