Colorectal cancer detected in 21 (3.8%) of 548 examined patients had various character of growing and localization. Exophytic growth of a tumor was detected by spectral-entropic analysis in 6 (29%) of 21 patients. Cancerous growth of lesser size (18 mm in diameter) in one patient looked exactly the same as flat polyp and was verified by application of spectral-entropic analysis. We managed to identify its morphological character after histological research only. Larger tumors, sized from 20 to 50 mm (in 5 patients) looked like asymmetrical focal growths with hyperchromogenic wall (6 points at Fleindler’s scale) and achromogenic center (1 point at Fleindler’s scale). In 15 (71%) of 21 patients carcinoma had circular type of growth. At such type of growth we detected thickening of a wall in an area of a tumor, its rigidity (rigidity was identified as a flattening of a wall and absence of haustration in this area), application of spectral-entropic analysis allowed to make more reliable judgment about carcinoma. Spectral-entropic analysis of a colonic wall, confirmed by histological study of cancerous growths, revealed adenocarcinoma in 20 cases and tubular cell carcinoma in one case.

Bioplasm 9d nls analyzer is good for us.
