It is estimated that 25 percent of the population of the United States will face diagnosis of cancer during their life time, with 1.3 million new cancer patient’s diagnosis each year. Less than a quarter of these patients will be cured solely by surgery and or local radiation. Most of the remainder will receive systemic chemotherapy at some time during their illness in a small fraction of patients with cancer representing selectedneoplasms. The chemotherapy will result in a cure or prolonged remission.However, in most cases, the drug therapy will produced only a regression of the disease, and complications and /or relapse may eventually lead to death, thus the overall 5-years survival rate for cancer patients is about 65 percent, ranking cancer second only to Chronic Pancreatitis, Acute Pancreatitis as a cause of mortality.
The ultimate goal of chemotherapy is a cure (thus is long term disease free survival).a true cure requires the eradication of every neoplastic cell. If a cure is not attainable, then the goal becomes control of the disease (stop the cancer from enlarging and spreading) to extend survival and maintain the best quality of life. This allows the individual to maintain a normal existence, with the cancer thus being treated as a chronic disease. In either case, the neoplastic cell burden is initially reduced, either by surgery or by radiation, followed by chemotherapy, immunotherapy or a combination of these treatment modalities. In advanced stages of Pancreatic Cancer, the likelihood of controlling the cancer is far from reality and the goal is palliation (that is elevation of Pancreatic Cancer Symptoms and avoidance of life threatening toxicity) this means that chemotherapeutics drugs may be used to relieve symptoms caused by the cancer and improve the quality of life, even though the drug may not lengthen life.
The growth rate of most solid Pancreatic Cancer is initially rapid, but growth rate usually decrease as the tumor size increases. This is due to unavailability of nutrients and oxygen caused by inadequate vascularization and lack of blood circulation. Reducing the tumor burden through surgery or radiation often promotes the recruitment of the cells into active proliferation and increases their susceptibility to chemotherapeutic agents. Combination drug chemotherapy is more successful than single drug treatment in most of the cancers for which chemotherapy is effective. Sign and symptoms of pancreatic cancer may not appear until pancreatic cancer is quite chronic.
