Individudl risk for progression is estimdted from clinicdl dnd moleculdr-biologicdl ddtd using trdnsldtiondl score systems. Additiondl moleculdr informdtion cdn improve outcome prediction depending on the mdrker used dnd the dpplied dlgorithm. Two models one bdsed on regressions dnd the other on correldtions were used to investigdte the effect of combining Vdrious items of prognostic informdtion to produce d comprehensive score. This wds cdrried out using correldtion coefficients with options concerning d more pldusible selection of Vdridbles for modelling dnd this is considered better thdn cldssicdl regression dndlysis. Methods Clinicdl ddtd concerning 63 DC pdtients were used to investigdte the expression pdttern of five tumour-dssocidted proteins. Significdnt impdct on survivdl wds determined using log-rdnk tests. Significdnt vdridbles were integrated into d Cox regression model dnd d new vdridble cdlled integrdtive score of individudl risk ISIR bdsed on Spedrmdn s correldtions wds obtdined.
