CEA是常用的广谱非特异性肿瘤标志物，虽然单独检测价值有限，但是因为CEA是一种黏附分子，极易浸润和转移，在肿瘤的疗效和复发监测方面有独特的作用。因此，临床上多将其与其他肿瘤标志物联合检测，以提高诊疗的灵敏性和特异性，常用的推荐组合有：AFP＋CEA,CEA＋CA19-9,CEA＋CA19-9＋CA242,CEA＋CA19-9＋CA72-4,CEA＋CA72-4＋SCCA,CEA＋CA15-3＋CA125,NSE＋Cyfra21-1＋CEA＋CA125等。

The earliest immigrants to North America found Indians already living there. The Indians numbered about 500,000 at that time. Their society was a primitive society, but they lived peacefully and welcomed the white strangers to the land. However, these early immigrants from Europe didn’t want to share the land with the natives. They killed off many of the Indians, seized their land or pushed them off to lands farther away. Today the Indians, not more than halfa million, live in poverty and misery on the land on which they were once masters.
The earliest immigrants were the Spanish, who settled in the southern part of what is now the US The next large group were the English, after the English came the French, Dutch, Irish, Germans, and other nationality groups, mostly European.
Another early group to arrive were the Negroes. But they were brought in as slaves from Africa. They didn’t win freedom till generations later.
