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。

My husband was ordered out on a long-term duty,and I was left in a tiny shack(棚屋) alone. The heat was  23  -almost 125 0F even in the shade of a cactus(仙人掌)。 24  a soul to talk to . The wind blew non-stop ,and all the food I ate ,and the evry air I breathed,were  25   with sand , sand , sand !
I was so sorry for myself that I wrote to my parents. I told them I was  26   and coming back home.I said I couldn’t stand it one minute longer. I  27  be in prison! My father answered my  28  with just two lines-two lines that will always sing in my  29  - two lines that completely changed my life :
Two men looked out from prison bars
One saw the mud ,the other saw the stars
I read those two lines  30   I was ashamed of myself. I made up my mind I would find out what was good in my present  31  ; I would look for the stars
