Prevenirea cancerului prin intermediul unor programe de screening
Although not-fulfilling all "the Amsterdam offers a homogenous but apparently rigid frame, considering criteria" for eligibility in the HNPCC group, the patients current molecular genetics research. Thus, more and more with colo-rectal cancer and positive family history showed patients that do not fulfil entirely those criteria and an morphoclinical features which suggested poor prognosis important number of patients with sporadic cancers are found compared to those with negative family history.
A comparative analysis of the morphoclinical Key words features in non-polyposis colo-rectal cancer patients with Hereditary colo-rectal cancer - Amsterdam Criteria - positive family histories which fulfil entirely colon cancer genetic marker partially prognosis "the Amsterdam criteria" versus colon cancer genetic marker patients with sporadic non-polyposis colorectal cancers.
Patients and methods.
We performed a retrospective a n a l y s i s on c o l o - r e c t a l c a n c e r p a t i e n t s o p e r a t e d consecutively by the same surgical team. Colon cancer genetic marker patients were Rezumat allocated into two groups: group A - patients with colo Introducere.
The cases respecte "criteriile Amsterdam" care asigură un cadru with familial polyposis and those with uncertain family history omogen dar aparent rigid în lumina noilor cercetări de colon cancer genetic marker excluded.
We analyzed comparatively the differences genetică moleculară.

Astfel, la tot mai mulţi pacienţi care in sex, age, stage, tumour site, pathological characteristics. A number of colo-rectal cancer patients Scopul cercetării.
Analiza comparativă a particularită underwent surgery between and their medical ţilor morfo-clinice la pacienţi cu cancere colo-rectale non- records were assessed retrospectively.
- The benefits are certain in some cases: life years gained for those with curable disease, avoidance of morbidity, reassurance that the disease is at a very early stage, avoiding expenses of treatment for advanced cancers and extra years of productivity.

The group A contained polipoase cu antecedente heredo-colaterale pozitive şi care 30 patients with colo-rectal cancer and positive family întrunesc parţial sau total "criteriile Amsterdam" faţă de history and group B consisted of patients with colo pacienţii cu cancere colo-rectale non-polipoase sporadice.
We noted Material şi metodă.
Au fost analizate retrospectiv important differences between the two groups regarding age cazurile de cancere colo-rectale operate consecutiv de in group A we found significantly more patients aged under aceeaşi echipă chirurgicală. Au fost Vol.

- Iniţial s-a vrut a fi un marker serologic specific pentru carcinomul colorectal care să pună precoce diagnosticul la pacienţii asimptomatici, dar curând s-a demonstrat că niveluri serice ridicate apar şi în alte cancere, în afecţiuni non- maligne intestinale şi chiar la indivizi normali atunci când îşi schimbă brusc obiceiurile de fumat sau băut.

Mircca Cazacu antecedente heredo-colaterale incerte. Grupul A a cuprins 30 family history were excluded. We analyzed comparatively pacienţi cu cancere colo-rectale şi antecedente heredo- the differences in sex, age, Dukes stage, tumour site, colaterale pozitive iar grupul B a cuprins de pacienţi pathological features.
Deosebiri importante au fost decelate între cele significant.
Their medical records were multe cazuri cu structură histologică de carcinom difuz, analyzed retrospectively.
The group A consisted of 30 patients with positive family Concluzii. Deşi colon cancer genetic marker noştri cu cancere colo-rectale history and group B contained patients with negative şi antecedente familiale pozitive nu întrunesc toate family history.
The analysis of the morpho-clinical elements "criteriile Amsterdam" pentru încadrarea în grupul CCENP showed: aceştia prezintă particularităţi morfo-clinice de gravitate 1. Sex - we noted a relatively uniform distribution of the crescută faţă de pacienţii fără antecedente heredo-colaterale.
Age - the median age was Staging - considering the distribution of the cases in entirely "the Amsterdam criteria". The relationship with the "Amsterdam Criteria": there rectal cancer in order to detect the differences between was no patient in group A that fulfilled all "The Amsterdam patients with positive malignant family history and those Criteria": 5 patients fulfilled colon cancer genetic marker criteria, 9 patients fulfilled 2 with no such history.
Discussions Material and methods The scientific approach of the hereditary colo-rectal We analyzed retrospectively cases of colo-rectal cancer cancers has changed very much after the colon cancer genetic marker of tumor operated on by the same surgical team. The patients were microsatellite instability. Hereditary non-polyposis colo-rectal cancer between dogma and reality There are certain conditions which need to be fulfilled We consider that by confronting this situation, we can in order to permit the allocation of a patient in the HNPCC apply one of the new clinical subdivisions of colorectal group conditions defined in as "The Amsterdam cancer which allows the allocation in one of the 5 groups: Criteria".
The presence of colo-rectal cancers pathologically 2 HNPCC suspect - the cases that do not comply with all confirmed in at least three members of the family, one of the standard criteria; them being a first degree relative to the others.
Colo-rectal cancers present at least colon cancer genetic marker two successive comply with the standard criteria but have relatives suffering generations. At least one of the family members diagnosed when 4 juvenile types - cases that fulfil only one criteria and aged under Although none of gene mutation This aspect has important - the estimation of individual risk, currently done by consequences regarding the indication of genetic testing of means of genetic testing, with all hpv vaccine pris social and economical all family members and the eventual costs of screening consequences, evaluation of certain risk groups 5.
Thus we use on colon cancer genetic marker Thus, taking as genetic criteria the presence of mismatch- large scale family history investigation and also laboratory repair-gene mutation, the situations which suggest the tests and we hope the future will bring us new techniques presence of a hereditary colorectal cancer are: such as the detection of human leucocyte antigens as genetic - the presence of colorectal cancer in at least 3 family markers in colo-rectal carcinoma Among the 30 cases operated by us follow-up.

Cellular phenotypic changes characteristic of EMT can be induced by the absence of transition cofactor p involved in cellular regulation. Loss of syndecan-1 marker is associated with local tumor stage and metastasis. Modulators of protein kinase resistance was associated with changes in genes involved in EMT including vimentin hyperexpression and genes involved in invasion N-cadherin with a decrease expression of genes involved in epithelial cell adhesion E-cadherin. Progression in colon cancer is characterized by activating mutations in Ras genes and tumor growth factor action.
