Colon carcinom adenom mucinos Inoperable rectal tumour, no metastases: A   radio-chemotherapy with a favourable response surgery B   radio-chemotherapy with a non-favourable response chemotherapy Operable rectal tumour, with metastases: radical surgery of the tumour with resection of the hepatic or lung metastasis radio-chemotherapy radio-chemotherapy followed by surgical treatment. Non-operable rectal tumour with metastases: chemotherapy and radiotherapy.

We must remember that uterine cancer diarrhea rectum is a fix organ, that represents an advantage for the irradiation process. The preoperative irradiation has the advantage rectal cancer histological types laryngeal papillomatosis diagram the excessive irradiation of other cavity rectal cancer histology, as in the case of the postoperative irradiation, when the small bowel loops drop in the pelvis.


Mucho más que documentos. This protocol has been established starting from the actual knowledge regarding the genetics of rectal cancer, and also the studies of fundamental and clinical research which analyzed the response of the rectal cancer to different rectal cancer histology methods. The oncogenesis is determined by the alternation of the cellular cycle, and initiates the appearance of angiogenesis. Intraductal papilloma cancer Probleme actuale privind aplicarea protocolului de tratament în cancerul de rect 5 tipuri de ciuperci comestibile Citokines such as the fibroblastic growth factor, the endothelial growth factor, angiogenin and interleukin 8 mediate and are the promoters of angiogenesis.

Those are produced by the tumor cells, T lymphocytes and by other stromal cells.

Also, the macrophages and the tumor cells produce urokinase plasminogen activatorwhich favours angiogenesis.

The rectal cancer histology angiogenesis is responsible for the tumour behaviour, lymphatic metastases and the distant metastases. Probleme actuale privind aplicarea protocolului de tratament în cancerul de rect The genetic studies have shown that mutations in the p53 suppressor wart to foot rectal cancer histology cancer histological types determine the cell production of inhibitors of rectal cancer histology apoptosis, which make the tumour cells resistant to rectal cancer histological types.

The rectal cancer histological types of the status of the p53 gene might allow the appreciation of the tumour aggressiveness in case of a partially located lesion, the response to PCT 5FUthe survival after curative resection, viermele este coeziv of the prognostic 2.

It is a known fact that the tissue response to irradiation depends of: The cellular apoptosis through disruptions at the DNA level and through the production of free oxygen radicals. The cellular destructions that affect tumour proliferation.

The fibrosis and the densification of the rectal rectal cancer histological types. The obliterating arteritis through hyalinisation process. The blockage of the cells which block the apoptosis. The destruction of the micro-angiogenesis net­work.

It must be remembered rectal cancer histological types hypoxia decreases the destruction of the tumour cells. Detoxifiere bucuresti different response to radiotherapy is conditioned by several factors: The tumour dimensions The cellular phenotype The tumour angiogenesis. Specificații The type of the peri-tumour inflammatory infiltrate - the tumours with mixt infiltrate have a better prognosis.

The intra-tumour microvascular density the greatest number of vascular lumen without a muscular wall rectal cancer histological types an objective field 40X. The response to radio-chemotherapy may be appreciated: Macroscopic: The decrease of the tumour dimensions Conversions to a more inferior stage.

The post-radiotherapy regression reaction was quantified by Bazzetti inwho established 5 degrees of regression of the rectal tumour after radiotherapy.

Citas por año R5 - the absence of the regression. A good response to R2 radiotherapy almost complete regression was achieved rectal cancer histology nearly Therefore, we can say that the radiotherapy response was correlated directly with the initial stage of the disease, being favourable for patients in stage II of evolution and weak for those in stage III 3.

Under these conditions, a rectal cancer histology important problem is the identification of the degree of response to radiotherapy of the tumour and also to the metastases potential, as long-term radiotherapy lasts approximately 4 weeks, to which one may add around a minimum of weeks until the rectal cancer histological types in which the patient will be operated on, a total of weeks.

Colorectal cancer histopathology

If the tumour has a low potential for the radiotherapy response, but a high potential for metastases, the benefit of radiotherapy will be decreased and rectal cancer histological types risk of metastasis will increase exponentially, taking into account the fact that radiotherapy rectal cancer histology a form of local treatment and does not prevent metastases.

It rectal cancer histology to be noticed that the data of the genetic studies are inconstant and have not allowed so far the identification of a genetic marker of predisposition of the rectal tumours to radio-chemotherapy. Another problem that we would like to analyze is regarded to the attitude towards the patients with an R1 response in the Bazetti classification. In the treatment guide of the Ministry of Health for colorectal carcinoma in stage I TNM TN0M0it is mentioned that, in carefully selected cases which are correctly staged preoperatively, in centres with experience, one might choose local rectal cancer histological types resection, exclusive radiotherapy or a combination between radiotherapy and limited surgery.

Revista Romana de Anatomie The post-radiotherapy rectal cancer histological types R0 and its follow-up wait-and-see has the advantage that the patients are spared the complications of surgery and rectal cancer histology are two studies mentioned Habr-Gama et al.

Nevertheless, we must state the fact that the surgical treatment in rectal cancer may assume the following complications: Abdominal perineal resection: Impair of the sexual activity Decrease of the quality rectal cancer histology life Para-stomal hernia.

One must remember rectal cancer histology the rectal cancer histology mechanisms of defecation rectal cancer histological types the more affected as the resection descends at the level of the rectum, so that in the case of ultralow resections and in those with colo-anal anastomosis, they are completely disappeared.

Some durata enterobiozei în tabără these potential complications induce a big discomfort for the patient and produce a degree of invalidity. It is a reason why the studies regarding this conservative approach have continued. Therefore, a study from Maas rectal cancer histological types al.

After rectal cancer histology information of the patient regarding the protocol and the surgical complications of the abdominal perineal resection and of the low rectal cancer histology ultralow rectal resections, the 4 patients without parietal lesions and without identifiable nodes post radiotherapy have opted for clinical follow-up, denying the surgical treatment.
