After performing an operation, feel OK originally All troubles end when the main trouble ends. , eradicate serious illness, leave with the disease. But, it often worry, mix especially the disease related cancer, be brandish more do not go.

For example prostate cancer, after a few patients perform an operation to excise tumor, before long the illness has a relapse, the torment of continue to bear serious illness, make a person anxious really.

In Singapore, prostate cancer is the 6th big cancer of the male. Because this disease is cancer of a kind of tall hair, be next to lung cancer in cancer mortality of the man so. In the past 30 come for years, rate contracting cancer increased 3 times, patient with many years old 60 person for most.

Prostate cancer sicken leads the black of the Caucasian that highest is the United States and United States, prostate cancer is the United States killer of the 2nd big cancer, divest every year the life of 30 thousand American.

Label of substance of two kinds of protein develops a case

Recently, american scientist carries old research, discovery has substance of two kinds of protein to be able to mark inside human body the development case that gives prostate cancer.

They discover one kind is called " EZH2 " albumen is called with another kind " ECAD " protein substance. When " EZH2 " appear in great quantities inside patient system, and " ECAD " when decreasing relatively, this adumbrative this patient will get again the descent of cancerous demon.

Researcher expresses, the prostate cancer development inside human body is not rapid, because this suffers from inchoate prostate cancerous person, must not use an operation to treat immediately, can adopt " monitor its develop a case further " redo decision. Be opposite especially for a few patients that have chronic, do the adverse effect that can avoid remedial hind and produces so.

The scientist excises the prostate cancer patient of the operation to undertake study to already doing prostate 259 times. Because the recrudesce of cancer needs the time that wants several years normally, so researcher basically checked the antigen that concerns with prostate in patient blood, regard cancer as a signal that whether grows afresh its.

Researcher says, below normal circumstance, once prostate is excised, of this kind of antigen measure number to be become with respect to meet an emergency 0. Accordingly, whether does the prostate cancer patient that judges cure of art of handle of a classics have a relapse, whether must lift through observing this kind of antigen in its blood. Of this kind of antigen elevatory mean when undergo surgery, cancer cell already diffused the other position of the body, or explain the operation at that time fails to eliminate the cancer cell inside focus of a disease entirely clean.

"One tall one low " demonstrative recrudesce is likely

According to afore-mentioned research results, the prostate antigen that has 53 patients is elevatory, the specification already had recrudescent sign. Below this kind of circumstance, researcher undertook to the cancer cell of these patients biochemical marker is checked again, as a result discovery is in " EZH2 " albumen index is elevatory and " ECAD " in the patient that drop is being spent in albumen index, occurrence cancer of nearly half patient has a relapse.

Study the result shows, index of this kind of albumen " one tall one low " circumstance, the possibility that explains cancer patient has a relapse increased double.

Advanced and advisory Doctor Chen Yingjun says specialized subject of make water of secrete of center of white medicine of Yi Li Sha: "This kind ' one tall one low ' law of albumen index calibrating, just attribute research level, had not used formally in clinical on. Current, majority still passes prostate antigen (PSA) comes calibrating prostate cancer, its accuracy is taller. Its accuracy is taller..

Prostate cancer shape

Prostate cancer divides a level, 10 years ago, because calibrating technology is insufficient perfect, the patient is sufferred from to go up by calibrating when prostate cancer, already arrived commonly the 3rd or final first phase. Now, 30% when carrying patient's condition of prostate antigen calibrating to 50% patients, come on period belong to initial stage more or the 2nd phase, increased the odds that the patient recovers greatly. The person that first phase accepts treatment (electrotherapy or operation) , can survive 10 years or so.

Have the man of prostate cancer, pee difficulty, perhaps appear the circumstance of frequent micturition, have some of patient weight cut, if spread to skeleton, can feel bone is painful.

Pass blood test, can measure the amount of antigen of the prostate in haemorrhage fluid, antigen is secrete by prostate, if the amount is high, suffer from probably on prostate cancer, also may be to mirror a prostate to get the influence of some respect, must pass biopsy ability to decide.

Inchoate prostate cancer, can pass blood test to be able to confirm.
