Abstract:
The colon carcinoma is the second most frequent cancer among male and female population around the world. According to the histological data, the most frequent colon carcinoma is adenocarcinoma (90 %) with rectal and sigmoidal localization (75 %), followed by ceccum and ascendant colon (16 %). Approximately, one million people annually suffer from this carcinoma and half of them die [1]. Remaining 10 % of cases include other histological types of colon carcinoma such as carcinoid, anaplastic carcinoma, and squamous carcinoma as well as different types of lymphomas and melanomas. A number of optical techniques are used for detection and differentiation of colon carcinomas with different success. The opto-magnetic imaging spectroscopy (OMIS) is a novel method, which was successfully applied for differentiation of various types of colon carcinomas after its noticeable application in detection of hydrogen bounds in water [2] and characterization of epidermal skin layers [3]. Investigations have included 60 patients with histologically confirmed adenocarcinoma and 2 patients with other colon cancers (one with MALT lymphoma and the other with metastasis of melanoma). Digital images of healthy mucous and tumor infected tissues were taken under the white light and reflected polarized light, ten times each, and were processed with spectral convolution algorithm according to the OMIS method [4]. It was shown that the OMIS findings of adenocarcinoma patients significantly differ from findings of MALT lymphoma and melanoma patients. Different OMIS results were also obtained for MALT lymphoma and melanoma patients.
