I. Takanami et al., TRANSFORMING GROWTH-FACTOR-BETA ISOFORMS EXPRESSIONS IN PULMONARY ADENOCARCINOMAS AS PROGNOSTIC MARKERS - AN IMMUNOHISTOLOGICAL STUDY OF 120 PATIENTS, Oncology, 54(2), 1997, pp. 122-128
The transforming growth factor (TGF)-beta 1, TGF-beta 2 and TGF-beta 3
expressions were immunohistologically studied in tissues specimens fr
om 120 patients with a pulmonary adenocarcinoma. The results of a univ
ariate analysis indicated that the expression of each of the TGF-beta
isoforms correlated with the prognosis. Of the three prognostic factor
s examined using Cox's stepwise regression model, the TGF-beta 1 isofo
rm was found to correlate with survival. These findings suggest that T
GF-beta isoforms play an important role in tumor progression and that
the TGF-beta 1 isoform is a useful prognostic marker for pulmonary ade
nocarcinomas.
