Undertake occult blood examination can reduce the mortality of knot rectum cancer regularly

According to Danish scholar report, if written guarantee crowd of rectum cancer tall danger can hold to biennially to have occult blood general investigation, its mortality can be reduced significantly.

Europe ascends the O of hospital of university of a place of strategic importance. D. Dr. Jorgensen and its work in the same placing undertake to repeating occult blood census is right knot rectum cancer (whether can CRC) reduce patient mortality to undertake assessment. Researcher has general investigation through Hemoccult-II above all, finish only first of census suffer the person that try to just can have subsequently examination. If detect,the result shows masculine gender, have colonic lens check.

Result discovery, from first census begins to come the 7th times census, census group and contrast the average age of the group increases to 70 years old by 59.8 years old, male / female scale by 0.92 reduce to 0.81. Positive rate is fluctuant at 0.8% to 3.8% , 7 times the accumulative total after detects positive rate is 5.1% . The patient of 4.8% undertook colonic lens is checked at least one times.

Researcher points out, the CRC mortality of census group is remarkable and inferior (opposite danger spends RR: 0.82) . And, of the mortality of tumour of above of second shape colon reduce most remarkable. With compare to taking a picture, census group is reduced in the RR after detecting 7 times to 0.7 the following. But, mortality of blame CRC dependency did not see notable difference.

Additional, with undertake all scrutator is compared, the dangerous sex that dies at CRC without respondent increases significantly. And, accept first census, but the tendency that did not undertake subsequently sex of scrutator existence danger increases.

Dr. Jorgensen thinks, use Hemoccult-II to undertake two years period the mortality that census can reduce CRC continuously. And, be necessary to have check of lens of second shape colon jointly at the same time.

　　 Sieve of handy and effective knot rectum cancer checks an instrument

New York, on December 5 (Reuter medicine news) publish this year a research on magazine of academy of name nation tumour will make clear in November, the old people of dangerous to cancer of rectum of 60 years old of the left and right sides, common forms sex, lens of colon of Chan Ciyi shape is safe and effective sieve checks an instrument.

Dr. Nereo Segnan of center of precaution of Italian Turino tumour and its work in the same placing undertook sieve of lens of colon of Chan Ciyi shape investigate a test (SCORE experiment) .

Result discovery, share patient of cancer of 54 knots rectum, occurence rate is 0.54% , among them the tumour of 57% is located in knot rectum far end. Lens of second shape colon is safe, only one produces perforation, the ache when most patient thinks to check is slighter than what anticipate.

Dr. Segnan thinks, the preliminary result that SCORE experiments makes clear lens of second shape colon is safe and effective knot rectum cancer the sieve checks an instrument, those who study discovery is taller receive exhibition period and occurence rate of cancer of inchoate knot rectum, check of as colonic as second shape lens is mixed to occurence rate of knot rectum cancer the tally of distinct effect photograph that die in one's bed leads.
