[Screening for colorectal carcinoma in the region surrounding the city of Frýdek-Místek between 1999 - 2001]. / Screening kolorektálního karcinomu v regionu mesta Frýdek-Místek v letech 1999-2001.

The results of the colorectal carcinoma screening project in the region of Frýdek-Místek for the period of 1999 - 2001 are presented here. Of the 225 patiens diagnosed with carcinoma, 9 of the cases (4 %) were detected using the fecal occult bleeding test. Of 1000 people tested, a factor of 2.9 patients with carcinoma and 12.5 patients with adenomatous polyps were diagnosed, with 7.3 % test positivity. A statistically significant shift has been noted to detection in earlier stages of the disease (p = 0.05). From 49 - 53 % of the patients operated on in the period of 1999 - 2001 had their tumors in the stage A or B according to Dukes, a 13 - 17 % increase over the year of 1998. This shift was due above all to educating the local population.
