high CEACAM-1 expression is associated with an increased angiogenic activity in non-small-cell lung cancer and that the prognostic influence of CEACAM-1 might be derived from this association

SCC, CEA, Cyfra 21-1 and NSE are valuable in the early diagnosis of lung cancer among suspicious nodules in the lung, especially when they were assayed together for one patient.

CEACAM1 might be a useful marker in early diagnosis of non-small-cell lung carcinoma

Low Carcinoembryonic Antigen expression is associated with response to therapy in advanced non-small-cell lung cancer.

High serum carcinoembryonic antigen expression is associated with lung cancer.

CD66 is a potential tumor marker to differentiate lung adenocarcinoma-associated malignant pleural effusion from benign effusions.

High carcinoembryonic antigen serum levels are associated with lung Adenocarcinoma.
