Table 1. Differences in Prognostic Factors Between Patients With Early and Advanced Cancer.

	Early Stage	Advanced Stage
Prognosis	Years, decades	Months, weeks, days
Inception cohort	Cancer site specific Time of diagnosis Time of consultation	All cancer groups Admission/referral to palliative care or hospice
Prognostic factors	Clinical: stage, laboratory studies Pathological: histology, grade Molecular: gene, microarray Others: treatments, resources	Clinical: symptoms, laboratory studies Pathological: NA Molecular: NA Others: treatments, resources
Tools	Scores: IPI Programs: Adjuvant online	Scores: PaP, PPI Programs: PPS
Implications	Overall outlook on life span Worse prognosis = more intensive cancer treatment New cancer treatment → changes in prognostic factors	End-of-life planning Worse prognosis → limit cancer treatment Limited cancer treatment → same prognostic factors

IPI = International Prognostic Index, NA = not applicable, PaP = Palliative Prognostic Score, PPI = Palliative Prognostic Index, PPS = Palliative Performance Scale.
