Biocurex maakt bekend dat studies hebben uitgewezen dat de speciale bloedtest die zij uitvoeren vele malen accurater is dan een gewone PSA test in het al of niet vaststellen van prostaatkanker. Op de website van Biocurex staat het volgende schema dat ook terug te vinden is in studieverslagen, zie referenties onderaan dit bericht:

......................TEST.....................................................SENSITIVITY.........SPECIFICITY
PSA (Prostate Specific Antigen) cutoff = 4 ng/ml...................82%....................40%
or PSA with a cutoff = 15 ng/ml *.........................................25%.....................95%
RECAF (Cancer vs normals) **.............................................90%...................100%
RECAF (Cancer vs benign) ***..............................................88%...................100%

De onderzoekers pleiten voor een combinatie van deze test met een PSA test Wat zij zeggen is dat PSA een lokaal probleem in de prostaat makkelijker signaleert en dat een RECAF test daarna kan vaststellen of er ook sprake is van een kwaadaardige vorm van prostaatproblemen. Lees hieronder persbericht zoals Biocurex dit publiceert op hun website. Overigens lijkt deze RECAF test ook voor het vaststellen en opsporen van andere kankersoorten geschikt te zijn zoals darmkanker. We zullen de studies die daarover gaan volgende week eens nader bekijken.

Biocurex's RECAF Blood Test Outperforms PSA For Prostate Cancer Detection

According to the National Cancer Institute, “Most men with an elevated PSA test turn out not to have cancer; only 25 to 30 percent of men who have a biopsy due to elevated PSA levels actually have prostate cancer” [1]. This is because PSA is produced by prostate cells, whether they are malignant or benign and therefore, benign tumors also produce PSA in excess. Therefore, as noted in the Journal of the American Medical Association, PSA is not a suitable marker to screen asymptomatic men for prostatic cancer [2] and yet, for lack of a better test, it is used in regular checkups.

The PSA test is not specific enough to screen for prostate cancer. On the other hand, the high specificity exhibited by RECAF tests of prostate specimens, as well as in many other types of cancer, strongly supports the use of RECAF testing for screening.

Moreover, combining the PSA and RECAF tests could eliminate the false positives resulting from using PSA testing alone. PSA has the advantage of localizing the problem to the prostate and RECAF could then determine if the high PSA value is due to a cancer. This combination would also facilitate the introduction of RECAF into the market place since PSA testing is very common. The company is discussing such a combination of tests with major healthcare companies and laboratories presently performing PSA tests.

PSA projected sales worldwide for 2004 are $450M [3] and prostate cancer represents only 17% of all cancers [4]. Our preliminary results indicate that RECAF works better than PSA for the detection of prostate cancer; and previous data showed that it could be used in most types of cancer. A simple extrapolation suggests a market potential for RECAF of $2.6B per year. To date, BioCurex has reported highly positive results from testing many forms of cancer including prostate, stomach, lung, ovary, breast and colon. These amount to 2/3 of all types of cancers and we believe that RECAF will work as well for the other 1/3 of malignancies.

Dr. Moro, BoCurex’s CEO, stated: “We are extremely happy to report these results, which were obtained with a new version of the company’s blood cancer detection assay. This improved test uses monoclonal antibody technology, for which Milstein and Kohler received the Nobel price in 1984. Monoclonal antibodies offer many significant advantages over the conventional antiserum test we were using previously to prove the RECAF concept. Monoclonals are far more specific, they are very consistent from one batch to another and they are easy to produce in industrial quantities using tissue culture techniques.”

The American Cancer Society estimates that over 220,000 men will be diagnosed with prostate this year in the U.S. with 29,000 deaths attributable to prostate cancer.

The company also wishes to advise that it is continuing its efforts to re-establish itself for quotation on the NASD OTC:BB. The process is not a direct one but the company is committed to the goal of achieving a more advanced listing. We appreciate the patience of our investors at this time and we will provide the investment community with appropriate updates as they occur.

BioCurex is also progressing with its plan to license its RECAF technology. A licensing agreement would allow the company to work with healthcare companies experienced in the cancer diagnostic arena and allow BioCurex to benefit from their scientific and business expertise.
