Survival Analysis for the Recurrence of Cervical Cancer Among Patients Under Follows up Since 2012 to 2015

Abstract

Background: Cancer is one of the leading causes of death in the world and represents a tremendous burden on patients, families and societies. The aim of the study was intended to identify the determinant risk factors for the recurrence of cervical cancer and model the recurrence rate of cervical cancer for patients who have already got their first treatment. Methods: A Sample of 371 cervical cancer patients who start their treatment in 2012 G.C was included. To identify risk factors of recurrence of cervical cancer and examine the association between the recurrence time with different demographic and medical variables, the proportional hazard Cox regression and the Weibull regression models were applied. Result: Among 371, 83(22.4%) of them experienced recurrence.  The mean recurring survival time was 20.68months. Most recurrence is occurred at the beginning up to the tenth month after entry and then after the recurrence decreases. The cox model is h_i(t, x_i, )= h_o(t) exp(
