Stage 3 Cancer
Characteristics Of Stage 3 Pancreatic Cancer
The patients, who have reached this stage, in the majority of cases, may be having tumors inside the body, which cannot be surgically removed from the source, the process called in medical sciences as unresectable. This situation arises owing either to the fact the vessel connected with the pancreas has been interfered with by the tumor or there is a large scale invasion by the tumor on the vessels.
The patients who have reached this stage may receive some relief from obstruction in the bile duct, by going in for either of the prognosis as the case may be, they being either endoscopy or surgery, or by taking recourse to radiation. There are some cases where the patients may survive the administration of radiotherapy whether in combination with chemotherapy, or with radiation therapy. The patients who have reached this stage may volunteer themselves to undertake clinical trials on themselves of new drugs that have been formulated on a dynamic basis owing to ongoing research.
While the radiation therapy, to an extent, is able to alleviate the pain arising out of the tumor, it does not show encouraging results as far as the survival rates are concerned. The patients who undergo chemotherapy are shown to have responded to the dulling of the impact of the tumor, but here as well, the mortality rate is high, and the experts suggest that the patients should volunteer themselves for clinical trials.
One option available at this stage is the removal of pancreas by surgery, which may be accompanied either medication accompanying chemotherapy and radiotherapy or direct administration of chemotherapy and radiotherapy without medication which works as the supplementary agent in the treatment. The radiation therapy is utilized to shrink the size of the growth of the tumor. The other options available for mitigation of pain include blocking the celiac nerves, or neurosurgical procedures of the local variety.
There are also possibilities of going in for analgesic surgical biliary accompanied or unaccompanied with gastric bypass. The placement of stent through endoscopic surgery is also an option to stop the flow of bile outside its natural course inside the body. Once the tumor has been removed from the body, the post operative process would involve radiation therapy accompanied with other chemotherapeutic agents.
The idea of going in for surgery is guided by the premise that the patients should be able to have a good quality of life as long as they are able to survive, with least complications accompanying the life process. The placement of stents or self-expanding metal tubes, which is one of the options, is undertaken to drain the common bile duct to treat the obstructive jaundice which is a major complication arising out of pancreatic cancer, and is found to manifest during the third stage.
