If cardia cancer has metastasized to lymph nodes, there is still a possibility of improvement after active treatment. Lymph node metastasis of pancreatic cancer indicates that the cancer cells have broken through the basement membrane and spread to distant places. According to the TNM analysis, the staging of pancreatic cancer has generally reached T3 stage or above, M1 stage, and the prognosis of pancreatic cancer is relatively poor on the whole, however, if the patient is treated by surgery, endoscopic treatment, radiation therapy, etc., there is a greater chance of improvement, but the patient can not be completely cured in general. Besides lymph node metastasis, patients with pancreatic cancer may also suffer from weight loss, emaciation, hoarseness, anemia, hypoproteinemia and even dehydration. It is recommended to consult the gastroenterology department and thoracic surgery department of the hospital in time, improve relevant examinations under the guidance of doctors, and actively cooperate with the treatment to improve the survival rate and prolong the life.
