H. Matsumoto et al., CARBOHYDRATE PROFILES SHOWN BY A LECTIN AND A MONOCLONAL-ANTIBODY CORRELATE WITH METASTATIC POTENTIAL AND PROGNOSIS OF HUMAN LUNG CARCINOMAS, Cancer, 69(8), 1992, pp. 2084-2090
The expression of two carbohydrate markers-namely, 4C9 antigen, which
is an Le(x) antigen, and the Dolichos biflorus agglutinin (DBA) bindin
g site, which is an N-acetylgalactosamine marker-was examined histoche
mically in tumors and adjacent nontumorous tissues of 102 cases of hum
an lung carcinomas. In nontumorous tissues, the DBA binding site was e
xpressed more frequently than 4C9 antigen, and the DBA binding site ha
d a tendency to be expressed more significantly than in tumor cells. A
denocarcinomas and well-differentiated tumors had a tendency to more c
ell surface staining. Patients with tumors that expressed DBA binding
sites but not 4C9 antigen (4C9-, DBA+) had fewer metastasis and signif
icantly better prognoses than patients with tumors of other carbohydra
te profiles. Better prognosis of patients with 4C9-, DBA+ tumors was o
bserved in those with blood group A antigen and those without it, and
the better prognosis also was observed in patients with Stage I and II
IA disease.
