Cancer colon incidence, The epidemiology of hypopharynx and cervical esophagus cancer
Incidenta este mai mare la barbati ratio Scanexpert - Centre de excelentă în imagistică Se observa o crestere a incidentei in tarile in care riscul global era mic, in timp ce in tarile situate la risc inalt se observa o stabilizare a incidentei Europa de vest si Australia ; se raporteaza incidente in scadere in SUA, Canada si Noua Zeelanda.
Mures C. Considering the fact that in the specialized cancer colon incidence exists insufficient evidence and often contradictions regarding the morphologic and molecular characteristics found in the early stages of malignization and regarding the limits imposed by the usual photonic microscopy techniques, we considered necessary approaching a comparative ultrastructural study between the two types of cancer mentioned above. Aim: To highlight the ultrastructural changes in the colorectal adenocarcinoma compared with the gastric adenocarcinoma.
Material and methods: The study included a number of 21 patients diagnosed with colorectal and gastric cancer from which we gathered biopsies that were processed and analyzed using a Transmission Electron Microscope Philips CM Results: The ultrastructural study identifies common characteristics of the malign transformation of both colorectal cancer and gastric cancer and also a series of particularities for colorectal cancer inaccessible for common microscopy techniques.
Conclusions: New information about the aggressivity and the metastatic potential cancer colon incidence accessible through TEM examination, which can improve the therapeutic management of these cases.
