Although both stomach cancer and pancreatic cancer are malignant tumors, these two malignant tumors can still be saved clinically. Stomach cancer is a common malignant tumor in digestive system, and if it is detected early, diagnosed early, and treated early, early stage stomach cancer can still be clinically cured. Even in the middle and late stages of gastric cancer, it can be treated by chemotherapy, targeted therapy, radiotherapy, immunotherapy and other comprehensive treatments so as to make the patients survive for a long time. On the other hand, pancreatic cancer is a malignant tumor in the abdominal cavity. Due to the special anatomical location of the pancreas, pancreatic cancer is difficult to be detected at an early stage, and a lot of pancreatic cancers are already in the middle or late stage when they are detected, thus losing the chance of radical surgery. However, with the emergence of new chemotherapeutic drugs and targeted drugs for the treatment of pancreatic cancer in recent years, it is still possible to prolong the survival time through chemotherapy, targeted therapy, radiotherapy and other comprehensive treatments even for the middle and late-stage pancreatic cancer.
