A method for making a prognosis for a patient afflicted with a type of
cancer which comprises (a) determining in a sample of a tumor from the patient a level of expression for at least three biomarkers from the following group:
thyroid transcription factor-1 (TTF1),
signal transducer and activator of transcription-3 (STAT-3), beta-
catenin and
cyclin D1; (b) calculating a
score based on the levels of expression determined in step (a); (c) correlating the
score obtained in step (b) with a series of predetermined reference scores associated with a series of prognoses; so as to thereby make a prognosis for the patient.
