The Importance of Pancreatic Cancer Staging

The exact origins of pancreatic cancer development are not well known. The only proven factor is smoking. Extra drinking coffee or dependency on fat food is not proven causes of pancreatic cancer, as it was supposed earlier. The same question about alcohol drinking is unsolved. At the same time the existence of genetic predisposition to illness in some families were established more often than in others. The pancreatic cancer treatment depends on pancreatic cancer staging.

What are the pancreatic cancer types?

Tumors of pancreas may appear in the cells of excretory and endocrine parts. On the first part come 95 per cent of all malign tumors. Less often tumors of endocrine cells are met. The cancer may emerge inside the cyst - cavity formations. Cysts represent formations of huge size, filled with liquid. Its sides are paved with epithelium that causes the cancer. Unlike the pancreatic cancer, caused by excretory cells, such tumors are well-restricted and can be easily treated by operation methods. Stomach cancer can cause the pancreatic cancer. In such cases, there appear stomach growth, overreach stomach bounds, pullulate in the pancreas.

Pancreatic cancer symptoms have two levels of pancreatic cancer staging. On the early level of pancreatic cancer staging, disease almost does not disturb and the ill do not go to hospital. The first symptom is the pain in the epigastric area, which increases at night. Then the patient loses weight and feels weak. In advance pancreatic cancer staging jaundice, a lack of appetite, nausea appears.

Pancreatic cancer staging is fulfilled with TNM classification. Letter T means the primary tumor, letter N shows what the lymph nodes condition is and whether they include cancer cells, letter M describes late metastasis.

Five prostate cancer stages are distinguished.

1.) During the "0 stage", also called Tis, there is a primary tumor, no cancer cells in lymph nodes, no metastasis. On this stage, the patient stands a good chance for recovery.

2.) On the first stage of pancreatic cancer the tumor of 1-2 cm size is found, but there are still no cancer cells in lymphatic system, no metastasis. The chance for survival is about 5-35% for a 5-year period.

3.) The second stage of pancreatic cancer describes the cancer advance, when the tumor is 3 cm size; there are no lymph nodes affection, no metastasis. The expectancy for survival is 2-15%.

4.) On the third stage the cancer begins to spread into the human organism. There is a tumor in the pancreas, the cancer cells in the lymph nodes, but still no metastasis. The chance for survival is about 1-5%.

5.) The forth level of pancreatic cancer staging is divided into 2 periods: on the first there are tumors in the pancreas, lymph system is affected, but metastasis is absent. The patient has about 1-5 % probability on survival. The second period includes tumors in the pancreas, cancer cells in the lymph system and metastasis in the organism. The percentage of survived patients in a 5-year term is less than 1 %.

Among the all methods of pancreatic cancer treatment operation is the only effective one. However, the TNM classification does not show the permissibility of operation. The survival in 5 after the surgery and in a 5-year period pretty much depends on patient's age rather than on cancer stage.

The tumor may be considered as possible for surgery if the cancer is not spread into the organism and the major vessels are not involved into the tumor. The number of patients that can be allowed for operation is less than 20 % of all pancreatic cancer affected.
