To these important prognostic and predictive end points, this study makes two significant contributions.
A stepwise backward selection procedure was performed to select the variables that are prognostic factors; the end point is 10 years for breast and renal cancer and 5 years for lung cancer.
Further study of the VOT procedure is required to establish its true utility as prognostic indicator and an end point of resuscitation.
With pCR being increasingly used as a surrogate end point for prognostic outcome in clinical trials, it will become imperative to develop uniform methods for reporting response to chemotherapy to ensure reliability of this end point.
This retrospective analysis aimed to test for a prognostic and predictive effect of BMI on the end point DFS, distant recurrence-free survival (DRFS), OS, and safety.
We performed a prognostic study, using CBC as the end point, through a Cox model (Cox, 1972), taking into account the cutoff time previously defined.
However, in contrast to our study, early biochemical progression as estimated by increase in PSA values was used as end point for the prognostic evaluation [ 18].
A Cox regression analysis with overall survival as the end point identified independent prognostic factors among covariates including CEA mRNA status, tumour size, histological type, serosal invasion and lymph node metastasis.
The survival model can be considered as a drug-independent model relating a biomarker response (week 6 fractional tumor size change from baseline, based on individual predictions from the TGI model) and prognostic factors (covariates) to a clinical end point (PFS or survival time).
The benefit of viusid was also seen in the secondary end point of worsening of the prognostic scores such as Model for End-Stage Liver Disease and Child Pugh scores.
