Metastatic Neuroendocrine Cancer Prognosis
Metastatic neuroendocrine cancer prognosis - The neuroendocrine tumor is a rare tumor that presents complex problems for diagnosis and treatment. Even in the case of metastatic spread to the liver, there are some important differences in the nature of these tumors in comparison with gastrointestinal and pancreatic cancer. They usually show specific clinical symptoms and signs and the road dragged on, and the production of hormones or amines, which are responsible for specific clinical signs and symptoms and acts as a tumor marker, and inhibition of tumor growth and reduction of symptoms can be achieved by a specific inhibitor of the agent. Metastatic neuroendocrine cancer prognosis - About half of all tumors of the neuroendocrine described as not working, which means that the patient does not have symptoms associated with hormones.
Hepatic metastases may be managed with "dexter office" (to throw away as much of the tumor as much as possible), both during the initial operation or a later date, and is intended to relieve symptoms. (This contrasts with exocrine pancreatic cancer is "Regular ", in which patients with metastases is not a candidate for surgery to remove the tumor.) Alternative techniques for the management of liver metastases include radiofrequency ablation " of " (i.e. using a special energy on the tumor, which is very hot)), "Cryoablation" (freezing the tumor mass), and "" (chemoembolization injection deposits chemotherapy directly into the tumor vessels), all of which have been successfully applied.
Metastatic Neuroendocrine Cancer Prognosis
1. Surgical resection of the. Neuroendocrine cancer is one of a small number of tumors in which the surgical dexter operations provide some advantages for survival. Sittoreduktif surgery, a mainstay in the management of metastatic disease widely, focuses on the control of symptoms and improve survival by removing or destroying the Metastatic tumors are disseminated. In addition, the symptoms often associated with crippling many of these tumors can be reduced by reducing the tumor burden.In a series of patients with the inoperable disease who undergo surgery dexter operation, 50% of the patients reported increased the duration of the symptoms in an average of 39 months. Some reports indicate both carcinoid and neuroendocrine tumors of the pancreas that cause the hormonal response of the palliative operation for nearly all patients with a decrease in pain in 90% of patients. Improvement of symptoms is very important for patients who do not have medical options for managing their disease, such as erythema necrolytic migration glucagonoma. Metastatic neuroendocrine cancer prognosis - Aggressive resection of metastatic disease of the liver seems to be associated with increased overall survival although this conclusion is not based on randomized studies.

Some centers report that the 5-year survival in patients treated with resection of the liver for about 70-80%. Most recommend considering liver resection if more than 90% of tumors can be excised and less than 75% of the liver is involved. Aggressive resection of metastatic disease of the liver seems to be associated with increased overall survival although this conclusion is not based on randomized studies.

2. Hepatic artery embolization. Therapy hepatic artery embolization (HAE) is based on the anatomical observation that most tumors in the liver parenchyma receive most of their blood supply from the hepatic artery, while the Portal vein supplies most of the liver parenchyma Normal. Kemoembolisasi includes the infusion folder Vaso-occlusive into the hepatic artery to reduce blood supply to tumors, in conjunction with the infusion of high-dose chemotherapy. Coils, gel foam, vinyl alcohol, and the oil was used to create the iodinasi emboli arteries with the addition of doxorubicin, mitomycin C, streptozocin cisplatin and 5-fluorouracil.
None of these combinations, which generate great results. Contraindications for this procedure including the tumors, which make up more than 50% of the volume of the liver, bilirubin greater than 2.0, AST greater than 100, or thrombosis of the Portal vein. Various studies have shown a decline in hormone levels in more than 90% of patients. The answer to this response, unfortunately, was not much more than a year. The rate of complication may approach 20%.
3. Transplantation of the liver. Metastatic malignant neuroendocrine tumors of the liver were assessed as an indication of a liver transplant. In one of the largest, neuroendocrine tumor a series of 103 patients receiving a liver transplant. The survival of two and five years, respectively, are 60% and 47%. Survival without disease was 60% and the one year and 23% in three years. Prognostic factors, which favor, including age less than 50 years, the primary tumors in the lungs or intestines, and the pre-season transplant treatment with a somatostatin Analog.
4. Radiofrequency ablation. The provision of new access for those who have a disability of the liver is limited by the use of selective tumor thermal coagulation to destroy isolated metastases. In a retrospective study of patients with cancer metastatic pancreatic neuroendocrine and carcinoid, the researchers report the cleansing of the tumor in 17%-46% of patients. As well as improvement in symptoms recorded in 71% of patients with carcinoid syndrome, and 75% also reduced the 5-HIAA and CgA is at least 50%. Similarly, even if the data in neuroendocrine liver metastases is limited to small series, several studies have shown efficacy in the treatment of cancer hepatocellular inoperable metastatic cancer of the liver and colon.

Is Neuroendocrine Cancer Aggressive?
A high level of neuroendocrine tumors or aggressive tumors are divided into large cells and small cells, which differ depending on the appearance of the cells under a microscope. Both types of cancer are considered to be very "does not distinguish" which basically means that the cells look very primitive relative to the normal neuroendocrine cells and behave very aggressively. In the past, it is estimated that the large tumor cells are more common, but studies on 2016 found that 89 percent of the tumors are tumors of neuroendocrine small cells.In some ways, a high level of neuroendocrine tumors are similar to lung cancer small cell, and often respond to similar treatment, but less likely Associated with smoking in comparison with lung cancer small cell and small probably metastasis to the bone and brain.
Several studies have found that tumors occur more often on the right side of the colon (ascending colon), while recent studies have found that the most common location of these tumors is the rectum and sigmoid colon. Metastatic neuroendocrine cancer prognosis - Colon cancer Screening will not cause a significant increase in the prognosis of this tumor, although in one study, 30 percent of tumors found in connection with the adenoma. The majority (64 percent) of the tumor is metastatic stage 4 or at the time of diagnosis.
Diagnosed with neuroendocrine tumors at a high level not only scary, but it can be very confusing because the conditions are not too frequent. The prognosis of the tumors was, unfortunately, not changed significantly in the past few years, but advances in treatment, such as the advent of targeted therapy and immunotherapy offers hope that new treatments will be available in the future the New.
Metastatic neuroendocrine cancer prognosis - Consult with your doctor about clinical trials evaluating new treatments. Be your own adviser in the treatment of cancer and ask questions. Classify the help of your loved ones and let them help you. In addition, many people find it helpful to reach out to the community on-line support.
