Usefulness of tissue polypeptide antigen in staging, monitoring, and prognosis of lung cancer.
A study of tissue polypeptide antigen (TPA) serum levels was conducted in patients with various cell types of bronchial carcinoma. A total of 548 assays (226 pretreatment) were evaluated. In all, the sensitivity of the test at diagnosis was 61 percent. It varied considerably in relation to the extent and site of disease. Individual pretreatment values of TPA correlated significantly with the stage of disease. Similarly, posttreatment TPA values related to disease evolution. In small cell carcinoma, eight of the 29 meaningful changes in follow-up levels of TPA preceded clinical recognition of disease status variations. Raised pretreatment values of TPA were significantly associated with a shortened survival. These results indicate that TPA may contribute to staging, monitoring, and prognosis of lung cancer.
