In this retro-/prospective study, we evaluated the prognostic potential of
pretreatment levels of Tumor Markers (CA15-3, CEA, TPS) in 67 advanced brea
st cancer patients (pts) treated by Taxol which were followed up for 4 year
s. Univariate analysis of pretreatment marker levels (accepted cut-off leve
rs) showed significance for TPS and CEA only, but not for CA15-3 (The marke
r for routine treatment monitoring). Median survival time of pts with pre-T
axol low levels of TPS and CEA were 21.3 months and 16,5 months as opposed
to high marker levels; 9.0 months and 9.7 months - respectively. Survival w
as best correlated to low TPS treatment entering levels. TPS retained signi
ficance also in the multivariate Cox's regression analysis, with a relative
risk of death of 2.3 vs 1. We conclude that TPS provides the most importan
t information for prognosis in advanced breast cancer pts treated by Taxol.
