Carcinoembryonic antigen in aqueous humor of patients with primary malignant choroidal melanoma.

Abstract: Carcinoembryonic antigen levels were simultaneously determined in the aqueous humor and in the plasma of the 3 patients with primary choroidal malignant melanoma undergoing enucleation. An elevated carcinoembryonic antigen level was detected in the aqueous humor of 1 patient with no increase in plasma CEA level. In the other 2 patients no such elevation was found. A local increase of CEA levels produced by the tumor is likely to occur. Further studies are required of CEA levels of patients with primary malignant choroidal melanoma as an aid in diagnosis and treatment of this condition.

Paraneoplastic syndromes, tumor markers, and other unusual features of malignant melanoma.

Abstract: Malignant melanoma is a neoplasm associated with a wide variety of paraneoplastic syndromes. In this review the many paraneoplastic syndromes associated with malignant melanoma are critically reviewed. Unusual nonparaneoplastic associations with malignant melanoma and tumor markers for malignant melanoma are discussed.

Primary malignant melanoma of right colon.

Abstract: We report a 62-year-old lady who presented with abdominal lump and neurological deficit. Investigations showed ascending colon mass, subcutaneous nodule and right parietal lobe lesion. Histology and immunohistochemistry were suggestive of malignant melanoma. The search for primary site was negative.

Elevated carcinoembryonic antigen levels in the milk of a nursing mother with inoperable breast cancer.

Abstract: Carcinoembryonic antigen (CEA) determinations performed in the milk of a nursing mother with an inoperable breast cancer revealed a 10-15-fold higher level compared with CEA levels in the milk of healthy nursing women. CEA was highly elevated in the milk of the tumor-bearing breast (1100 +/- 100 ng/ml) and moderately elevated in the milk of the clinically nonaffected breast (700 +/- 50 ng/ml). However, serum CEA levels were within normal range (9.8 +/- 0.5 ng/ml). The various theoretical and practical implications of this finding, including considerations for early breast cancer detection, are discussed.
