Memorial Sloan-Kettering Cancer Center
Biostatistics Seminar

Mithat Gönen, Ph.D.
Associate Attending Biostatistician
Memorial Sloan-Kettering Cancer Center


Many patients recur with symptoms following gastrectomy. This has been taken as a surrogate of disease biology by some and insufficiently frequent follow-up by others. The principle evidence used in making these arguments is the time between detection of progression and death. We will discuss how this can be subject to lead-time bias and propose an alternative based on multi-state modeling. Semi-parametric and fully parametric approaches will be considered for comparing the lifetime of patients recurring with and without symptoms.
