[Orosomucoid prealbumin ratio in bronchopulmonary cancers]. / Rapport orosomucoïde sur préalbumine dans les cancers broncho-pulmonaires.

ABSTRACT

Lung cancer is a common pathology with high mortality due to late diagnosis. The 1987 TNM classification clearly defines the different steps and their prognosis. Although the prognostic value of some biological parameters (mainly serum LDH, sodium and/or albumin) has been established, these are not much used. We have prospectively studied the serum levels of seven proteins (RBP, prealbumin, albumin, transferrin, haptoglobin, orosomucoid, CRP) and we demonstrate the predominant value of prealbumin for the establishment of the prognosis of lung cancer; determination of orosomucoid increases the prognostic value of prealbumin. We confirm, for lung cancer, the prognostic value of the orosomucoid-prealbumin ratio, already known for other cancers.
