Monoclonal antibodies are used to observe serum antigens associated with malignances. The tumour markers are most utile for supervising response to therapy and observing early backsliding.

Tumor markers are particular molecules released by tumour cells, found in high degrees in patients with malignances. Each tumour marker is organ specific and is elevated in specific type of malignance and its degree in go arounding blood supply a hint about the type and badness of the disease. The blood degree is really utile for diagnosing, forecast and to look into return after intervention. Experiments were performed to look into and set up if there are any associations between the rule tumour markers viz CEA ( colon caner ) , CA125 ( ovarian malignant neoplastic disease ) and CA15.3 ( breast malignant neoplastic disease ) to the diagnostically utile macro-metals Calcium and Magnesium and to propose if the above two metals need to be analyzed along with the tumour markers for the diagnostic intents. The survey was done with the blood serum sample of suspected or established malignant neoplastic disease patients ( both work forces and adult females ) . For the samples, biochemical assay utilizing electro-chemiluminescence technique ( for CEA, CA 125 and CA 15.3 ) was used ; Calcium and Magnesium were analyzed utilizing manual dye-binding methods and the readings were acquired utilizing a semi car analyser. Appropriate statistical methods were used to reason that, there exists a really strong relationship between CA 125 and CA 15.3 ; and proved that CA 15.3 is linked to both metals Calcium and Magnesium ; whereas CEA shows an reverse correlativity with CA 125.

I. Introduction:

In recent old ages, research lab diagnosing has achieved a outstanding topographic point in medical services and hence lab services form an built-in portion of the wellness attention bringing.

In this survey, an effort has been made to look into and set up if there are any associations between the rule tumor markers viz. , CEA, CA125 and CA15.3 to the diagnostically utile macro-metals Calcium and Magnesium and to propose if the above two metals need to be analyzed along with the tumour markers for the diagnostic intents.

II. Reappraisal:

Monoclonal antibodies are used to observe serum antigens associated with malignances. The tumour markers are most utile for supervising response to therapy and observing early backsliding.

Tumor markers are particular molecules released by tumour cells ; found in high degrees in patients with malignances. Each tumour marker is organ specific and is elevated in specific type of malignance and its degree in go arounding blood supply a hint about the type and badness of the disease. The blood degree is really utile for diagnosing, forecast and to look into return after intervention. For illustration prostrate specific antigen ( PSA ) is a really specific and utile testing trial for prostrate malignant neoplastic disease and to supervise the response to intervention. The blood degree correlatives good with Digital Rectal Examination ( DRE ) .

The ideal marker for the intent of diagnosing would hold two features: 1 ) it would be secreted into the blood in mensurable concentration merely after the cells that produced it has undergone malignant transmutation and 2 ) sensing of it would allow decision as to the site of tumour from which it arose. The usage of diagnostic trials in the clinical scene is extremely controlled by regulative organic structures, but Tumor Markers have been peculiarly identified for particular consideration.

CARCINOEMBRYONIC ANTIGEN ( CEA ) : CEA, an oncofetal glycoprotein, is expressed in normal mucosal cells and over expressed in adeno carcinoma, particularly colorectal malignant neoplastic disease. CEA lift besides occurs with other malignances. CEA is non utile in the showing of colorectal malignant neoplastic disease. This trial should be ordered merely after malignance has been confirmed. CEA degrees typically return to normal within 4 to 6 hebdomads after successful surgical resection.

CANCER ANTIGEN 125 ( CA 125 ) : CA125 is a glycoprotein usually expressed in coelomic epithelial tissue during foetal development. This epithelial tissue lines organic structure pits and envelopes the ovaries.Elevated CA125 values most frequently are associated with epithelial ovarian, although degrees besides can be decreased in other malignances. CA125 degrees are elevated in approximately 85 % of adult females with ovarian malignant neoplastic disease, but in merely 50 % of those with phase 1 disease. Multiple benign upsets besides are associated with CA125 lifts, presumptively by stimulation of the serosal surfaces.

CANCER ANTIGEN 15.3 ( CA 15.3 ) : CA 15-3 is a high molecular weight ( 300 to 450 kDa ) polymorphic epithelial mucin, besides known as chest malignant neoplastic disease mucin, that is produced by many malignant neoplastic diseases of the chest. It is non used for showing, but is recommended as a follow up after chest malignant neoplastic disease has been treated. In some instances it will let a backsliding to be detected before going clinically evident. CA15-3 is non elevated during gestation. The per centum of raised values found in chest malignant neoplastic disease can be every bit high as 98 % , but this depends chiefly on the tumour phase of the patient population studied. Elevated degrees have besides been found in patients with lung malignant neoplastic disease ( 63 % ) and ovarian malignant neoplastic disease ( 80 % ) .

CALCIUM AND CANCER: Experts say inordinate Ca consumption may be unwise in visible radiation of recent surveies demoing that high sums of the mineral may increase hazard of prostate malignant neoplastic disease. & A ; acirc ; ˆ?There is sensible grounds to propose that Ca may play an of import function in the development of prostate malignant neoplastic disease, & A ; acirc ; ˆA? says Dr. Carmen Rodriguez, senior epidemiologist in the epidemiology and surveillance research section of the American Cancer Society ( ACS ) .

The inauspicious effects of inordinate Ca consumption may include high blood Ca degrees, kidney rock formation and kidney complications. Elevated Ca degrees are besides associated with arthritic/joint and vascular devolution, calcification of soft tissue, high blood pressure and shot, and increase in VLDL triglycerides, GI perturbations, temper and depressive upsets, chronic weariness, and general mineral instabilities including Mg, Zn, Fe and P. High Ca degrees interfere with Vitamin D and later suppress the vitamin & A ; acirc ; ˆ™s malignant neoplastic disease protective consequence unless excess sums of Vitamin D are supplemented.

MAGNESIUM AND CANCER: One of the first variety meats to calcify is the ovaries taking to pre-menstrual syndrome. High Mg diet has reversed the above position. There is no replacement for Mg in human physiology ; nil comes even close to it in footings of its consequence on overall cell physiology. Without sufficient Mg, the organic structure accumulates toxins and acid residues, perverts quickly, and ages prematurely. It goes against a gale air current of medical scientific discipline to disregard Mg chloride used transdermally in the intervention of any chronic or acute upset, particularly malignant neoplastic disease. Early marks of Mg lack are, loss of appetency, sickness, purging, weariness and failing. Increased lack may demo as numbness, fingling, musculus contractions and spasms, ictuss, personality alteration, unnatural bosom beat and coronary cramps. Severe lack consequences with hypocalcaemia and hypokalemia.Magnesium have a calming consequence on the nervous system and are often used to advance good slumber. It can be used to quiet annoyed and over aroused nervousnesss. Epilepsy is marked by abnormally low degrees of Mg in blood.

III. MATERIALS AND METHOD:

After wholly traveling through the literature reappraisal where Calcium and Magnesium, are cited either as causative factor in bring oning malignant neoplastic disease of a peculiar type by its lack or accretion, we decided to choose a sensible figure ( n=64 ) of suspected or established malignant neoplastic disease patients to measure if any association exist between the type of malignant neoplastic disease and the single metals.

Subject:

64 patients consisting of both male and female in the age group of 14 to 79 who reported to the out patient clinic for malignant neoplastic disease related symptoms ( everyday showing every bit good as established malignant neoplastic disease patients ) were enrolled for the survey. As the research lab has late established normal values for 3 tumour markers and 2 metals for which we wanted to measure association, we straight estimated those parametric quantities for the intent of happening an association. The topics selected consisted of 39 females in the age group of 14 to 71 old ages and 25 males in the age group of 24 to 79 old ages. In order to cover our survey for a broad scope of age and sex related topics.

SAMPLE COLLECTION:

As tumour markers and metals do non change due to fasting or non-fasting position, sample aggregation was done between 9-10.30 am for all the patients. Exact sample aggregation processs were followed, such as usage of sterile and disposable acerate leafs and vaccutainer for roll uping the samples. Qualified phlebotomist was used in all blood aggregation in order to forestall pre-analytical mistakes that may be carried to the check phase. This includes a right site of vein puncture and the force per unit area used to reassign the blood into the vaccutainer.

Sample Processing:

All the blood samples were allowed to coagulate at room temperature for 30 proceedingss, the tubings were gently tapped to displace coagulum adhering to the tubing and so centrifuged with the cap on in each tubing for 10 proceedingss at 2500 revolutions per minute. Serum from each tubing was transferred to another set of appropriate labeled tubings utilizing disposable plastic dropping pipettes. The samples were either analyzed instantly or preserved at 2-8 & A ; Euml ; sC if there is a hold in analysis.

BIOCHEMICAL ASSAYS:

Using the latest electro-chemiluminiscent analyser, ( Updated version of Enzyme Immuno Assay ) , used for the check of Hormones, Tumor Markers and Drugs, 3 tumour markers ( CEA, CA 125 and CA 15.3 ) were estimated. Extensive quality control steps were done so as to acquire accurate values.

For mensurating Calcium and Magnesium, manual dye-binding methods were used and the readings were acquired utilizing a semi car analyser.

IV. RESULTS AND DISCUSSION:

Table 1 shows the consequences obtained for all the patients, for the 3 tumour markers and 2 metals ( Calcium and Magnesium ) along with their ratio. As CA 125 and CA 15.3 refers merely to the female patients, it is therefore non presented for the male patients. The mean and the Standard Deviation for the same are given in this tabular array along with its normal scope.

It is clearly seen from the Table that, the mean values for the trials CA125 and CA 15.3 are extremely elevated. This is due to the fact that, a few patients had values in the unnatural scope, which contributed for the higher Mean and Standard Deviation. CA 15.3 excessively is on the upper bound, while, Calcium mean value is on the lower bound of the normal scope and Magnesium is on the average degree.

We neither have selected a separate control group, nor chose established malignant neoplastic disease patients, but have indiscriminately selected, patients who attended the Cancer Screening Program, at our Oncology Department.

From the single values obtained, we can see that, the bulk of the patient values are within the normal scope.

Since the exclusive purpose of the survey was to set up a relationship between the 3 tumour markers viz. ( CEA, CA125 and CA15.3 ) , and the macro-metals ( Calcium and Magnesium ) , we have presented all the information together in a individual Table.

As the average age of all the patients is 54, the age at which many people attend the malignant neoplastic disease testing plan, justifies that our survey was done utilizing patients go toing malignant neoplastic disease plan.
