The rectoprostatic fascia is a membranous partition in the lowest part of rectovesical bag. This split of the prostate and bladder of the rectum. It consists of a fibromuscular structure with several layers, which are fused together and cover the seminal vesicles. It is also called fascia Denonvilliers “, after French anatomist and surgeon Charles-Pierre Denonvilliers. Structure corresponds had rectovaginal fascia in women. At postoperative transsexual women, the vaginal cavity created by him. Rectoprostatic in the rear bumper also inhibits proliferation of prostate adenocarcinoma due to the invasion of the rectum is more often than is the invasion of other adjacent structures.

The objectives of the follow-up are to be diagnosed at an early stage or metastasis or tumors that develop later, but did not originate from the original cancer. The U.S. National Comprehensive Cancer Network and American Society of Clinical Oncology provide guidelines for the monitoring of colorectal cancer. A medical history and physical examination is recommended every 3 to 6 months for 2 years, and then every 6 months for 5 years. Carcinoembryonic antigen blood measurements follow the same time, but it is recommended only in patients with T2 or more lesions, which are candidates for intervention. A CT-scan of the chest, abdomen and pelvis can be considered for the first year, 3 years for patients who are at high risk of relapse (e.g., patients who are poorly differentiated tumors or venous or lymphatic invasion) and are candidates for therapeutic operation (to be treated). Colonoscopy can be done after one year unless it can be done during the initial braking by preventing mass, in which case it should be performed after 3 to 6 months. If villous polyp, a polyp> 1 centimeter or high grade dysplasia is found, it can be repeated after 3 years, then every 5 years. For other offenses, a colonoscopy can be repeated after 1 year. Routine PET scan or ultrasound, chest X-ray, complete blood count and liver function tests is not recommended. These guidelines are based on recent meta-analyzes showing intensive surveillance and close follow-up can reduce the 5-year mortality rate from 37% to 30%.

Cytopathology is a branch of pathology that studies and diagnoses diseases on the cellular level. Discipline was founded by Rudolf Virchow in 1858. A common application of Cytopathology a smear is used as a screening tool for the detection of pre-cancerous cervical lesions, and the prevention of cervical cancer. Cytopathology is also commonly used in the investigation of thyroid disorders disorders including sterile body cavities (peritoneal, pleural and cerebrospinal), and a wide range of other body sites. It is commonly used to aid in the diagnosis of cancer, but it also helps in the diagnosis of certain infectious diseases, and other inflammatory conditions. Cytopathology typically used for samples of the free cells or tissue fragments, in contrast to histopathology and studies whole tissues. Cytopathologic tests are sometimes called smear tests because samples can be smeared on a glass microscope slide for subsequent staining and microscopic examination. However, sputum samples can be prepared in other ways, including cytocentrifugation. Miscellaneous Pap tests may be used for diagnosis of cancer. In this sense, it is called cytology smear. Cytopathology is often less accurately called cytology, which means “the study of cells.”

Various normal function of cell growth, metabolism, and division may fail or operate in unusual ways and cause disease. Cytopathology is best used as one of the three instruments, the second and third are physical examination and medical imaging. Cytology can not be used to diagnose the condition of the patient and the replacement operation, to obtain a larger sample. An example is the thyroid FNA; many benign conditions can be diagnosed with superficial biopsy and the patient can return to normal activities immediately. If the malignant disease is diagnosed, the patient may be able to launch the radiation / chemotherapy, or it can have an operation to remove and / or stage of the cancer. Some tumors may be difficult to biopsy as sarcomas. Other rare tumors my be dangerous to biopsy as pheochromocytoma. In general, fine-needle aspiration can be done anywhere, it’s safe to put the needle, including liver, lung, kidney, and superficial masses. Many doctors are not trained to perform fine-needle aspiration biopsies correctly and then when they do not get diagnostic material believe that cytology is not useful. Proper technique takes time to master. Cytotechnologists and cytopathologists can help doctors by going to the procedures and assist with collection techniques. A “speed reading” is a look under the microscope and tell your doctor if sufficient diagnostic material is obtained. Sputum samples must be well prepared, so that the cells are not damaged. Sometimes more information about the model is helpful. Immunohistochemical staining and molecular testing may be performed, particularly if the sample was obtained using a liquid-based cytology. Often the “Reflex” test is performed, such as HPV testing of an abnormal Pap test, or flow cytometry of lymphoma model.

Gland cancer is a carcinoma derived from glandular tissue. The epithelial tissue, skin, glands, organs and cavities and body line that is not limited to the surface layer of a variety of other organizations. Epithelium can be derived from embryology from mesoderm ectoderm and endoderm. So that they have a secretory properties, necessarily, it is classified as adenocarcinoma cells need not be part of the gland. Poorly differentiated adenocarcinoma can be differentiated adenocarcinoma, but they tend to resemble the glandular tissue that they are derived from. By staining the cells biopsies, pathologist determines whether the other type of cancer tumor or adenocarcinoma. Adenocarcinoma, the spread of glands in the body, in nature, and as a result, is likely to occur in many tissues of the body. Each gland is not able to secrete the same substance, but as long, as is the exocrine function in a cell, is considered the shape glands and malignant called adenocarcinoma it. Endocrine glands, such as VIP-OM, such as pheochromocytoma and insulinoma, tumor rather than not referred to as adenocarcinoma in general, it is called a neuroendocrine tumor frequently. No abnormal glandular tissue, in the case of benign, the adenoma says. Normal, benign adenoma is not rare transition If you do not invade other tissues. Adenocarcinoma malignant, metastatic given enough time to invade other tissues, and so often.

Symptoms of this type of cancer can be pain in the abdomen, weight loss, fatigue and weakness. Tumor size is increased, you may want to block the passage of food with crushed. There is a possibility that the tumor can lead to blockage. There is an obstacle when the intestine is blocked, you can not move anything to itself. This causes the pain to severe nausea and vomiting. Can cause perforation tumor. In other words, the entire contents of the small intestine spill into the abdominal cavity when. Sudden severe pain, nausea, symptoms of perforation is vomiting. However, it is rare in itself. Tumor starts bleeding in the gut sometimes. Slow bleeding so that the number of red blood cells is low. In weakness and fatigue, and as a result, this is also known as anemia. there is a possibility that rapid bleeding stool becomes black, digestion, causing slowed from the blood. This will allow you to feel dizzy or patient even if unconscious.

The majority of colon cancer is adenocarcinoma. This is because has a plurality of inner gland tissue of the large intestine. Tend to be simple and tubular in appearance with a mixture of water absorption cells and goblet cells that secrete mucus normal colon glands. For secreting substances into the lumen of the large intestine, these glands are called glands, they are fluid the material. The purpose of these glands is double. The first is to absorb water from the feces back to the blood. In order to lubricate the feces dehydration now, the mucus in the large intestine lumen second aim. This is very important because that may lead to degradation of the stool column the establishment of lubrication of feces through which it passes into the rectum.

The glands of these, if you have received a series of changes at the genetic level, they will move in a predictable way these to be moved from benign colon cancer invasive, malignant. The study their paper, and Vogel, many more “Lessons from colon cancer is genetic,”. This suggests that colon cells lose the APC tumor suppressor gene, and a small polyps. Then, small polyps and that of K-Ras is activated, a benign adenoma. Not be attached to the end of it in the adenoma “cancer” does not suggest that it is of the benign and malignant adenocarcinoma. Gastroenterologist is using colonoscopy to find and remove polyps and adenomas of these you will not be able to continue to acquire genetic changes that they lead to invasive adenocarcinoma. And Volgelstein. Loss of p53 and DCC genes suggests that brought adenocarcinoma malignant further.

Grossly, the table seen in a different color than the surrounding tissue will show people. Often, bleeding from a tumor is evidenced by a tendency to increase the tumor vessels therein in a random manner through the secretion of a number of pro-angiogenic factors such as VEGF. The Histologically, the tumor was similar, are classified original structure as they were differentiated. Tumor cells that have lost the similarity of any original tissue structure shaped appearance and both are shown as poorly differentiated tumor cells. Tend to have a large nucleus with a prominent nucleolus grade, malignant tumor regardless. In addition, there is a significant increase in the incidence of cell division or mitosis.
