How does the tumor carry on in early days diagnosis

Used for diagnosing of tumor and discriminate to diagnose some tumors in the process of turning into in produce some a little bit especially different sign thing, measuresing these sign things can be used for in early days diagnosing of the tumor.
What call tumor mark thing
Take place in the tumor, in the development process, the change of different degree happen in some materials in its cell, this kind of can reflect cell bad the material changing be called a tumor sign thing and call a lump mark.Clinical up pass to various lump of object examination, can diagnose towards corresponding tumor to do in early days, after judging to prepare, monitor curative effect and tumor relapsed condition.
The lump mark has where several type
The lump mark that has been already discovered currently has several types as follows.
The protein lump marks:A foetus egg white(AFP) is most in common use and used for diagnosing liver cancer;Cancer Pei antigen(CEA), used for tumors, such as digest way, lung and mammary glands...etc. of with visit a monitor:Prostate gland especially different antigen(PSA), used for diagnosing a prostate gland cancer.
The sugar lump marks:Like CA125, CA199, CAl53 etc., after useding for preparing of tumors, such as lung, mammary glands, digest way and gynecology...etc. and with visit a monitor.
The Mao lump marks:Change in the cell cancer process in, because of having something to do with gene adjusting to control of some Mao occurrence change, the gene adjusts to control maladjustment and causes protein's synthesizing mess.Examine the variety of these Maos in the serum, can used for the diagnosis of tumor.The diagnosis that useds for delivering sex marrow lump more and transfers sex bone tumor such as the alkaline phosphoric acid Mao;The γ -valley ammonia Mao turns Mao Mao(GGT) and it together work Mao(GGTII) and the rock Zao sugar Mao Mao(AFU) is used for diagnosing liver cancer.
The hormone lump marks:The malignant tumor can secrete a different hormone, the hormone can immediately disappear after cutting off tumor;But the tumor relapse the hormone can increase Gao again.If the person floss film urges the monitor of diagnosis and treatment effect that the sex gland hormone(HCG) is used for a floss film cancer.
The lump mark has what function
Used for diagnosing of tumor and discriminate to diagnose some tumors in the process of turning into in produce some a little bit especially different sign thing, measuresing these sign things can be used for in early days diagnosing of the tumor.For example the A foetus egg white diagnose original hair at present liver cancer most especially different sign thing;The floss film urged sex gland hormone to diagnose a grape foetus, the floss film last skin cancer in early days of especially different index sign.According to the dissimilarity of some tumor index sign levels, can also conduct and actions discriminate a diagnostic reference.For example the normal reference of CAl99 be worth to 0~37 international unitsmilliliter, in 37~70 international unitsmilliliter is suspicious and some pancreas cancers and pancreatitis, more than 70 international unitsmilliliter several rates of malignant tumor obviously enlarge.
The judgment after preparing someone thinks, the height of CA199 levels and the size and course of illness of the pancreas cancer early, night relevant, and along with cancer cell of gradually with transfer but present to carry on sex ascension.Therefore, the effect a good many that the CA199 levels low surgical operation cuts off:The tumor after cutting off CA199 levels obviously descends or normal, better after preparing.
Monitor curative effect and relapse the effect of ① judgment surgical operation or chemotherapy:Some colons, rectum cancer CEA the level go up of sufferer, the Shu monitors its level behind and as follows decline to mean the surgical operation is effective, such as don't decline to mean surgical operation to cut off ill success or prepare behind poor.Descend such as CEA after the chemotherapy, mean to the chemotherapy sensitive, whereas invalid then.But for before the Shu CEA not high colon or rectum cancer sufferer, Shu's monitoring CEA behind then is nonsense.②Monitoring the tumor hasn't relapsed:Cancer lump through cure for good to after operation relapse, again the surgical operation cure for good of opportunity away below first time surgical operation, but it prepares behind and discovers to relapse closely related sooner or later.After the malignant tumor Shu of close with visit, the purpose lies in to early discover to relapse, with exaltation again cut off of cure rate.Such as to before the Shu CEA the sufferer of higher colon cancer, the demand periodically examines CEA, once it goes up once again, then hint to have the possibility that the swollen cancer relapses.According to the report way, colon cancer namely has CEA to go up for 2~13 months before appearing clinical symptom, as a result can guide clinical carry on "two times fish for Shu" in time.Equally, AFP increases Gao of original hair liver cancer, sufferer Shu periodically monitors AFP and is one of the important index signs that discovered that the liver cancer relapsed in early days behind.
Lump the mark be worth of in the diagnosis within tumor
The applied value of making sure a lump object contains 2, on being the lump's mark's sensitivity for the diagnosis a certain tumor, two is to diagnosis a certain tumor of particularity.The sensitivity is more high, the particularity is more high and do diagnosis and discriminate diagnostic value with it more big.If a lump marks sensitivity very high, but the particularity is bad, the value of the clinical application then lowers.
