M3 is an epitope of the tissue polypeptide antigen detectable in the serum by immunoradiometric assay. This epitope is referred to as tissue polypeptide-specific antigen (TPS). We examined the pretreatment TPS level of 160 non-small cell lung cancer (NSCLC) patients and 71 patients who suffered from non-malignant pulmonary diseases. The upper limit of normal values was 140 U/l. Using this cutoff, the sensitivity and specificity were 36 and 90%, respectively. The TPS was significantly higher in NSCLC patients with an advanced stage, a mediastinal lymph node involvement or a poor performance status. This level was significantly higher in the group of patients for whom the disease proved to progress during chemotherapy. In univariate analysis, patients with a high TPS level proved to have a shorter survival than patients with a TPS < or = 140 U/l. In Cox's model analysis, performance status, stage of the disease and serum TPS were the only significant prognostic variables. The low sensitivity of TPS precludes its use for diagnosis. However, the pretreatment TPS level adds information to the management of NSCLC inasmuch as it predicts a low sensitivity to chemotherapy and a poor prognosis.
