胃癌
胃癌病因繁多，幽门螺杆菌是其中重要的一种。胃癌的症状包括早饱，梗阻和出血，多在疾病后期出现。胃癌主要依靠内镜进行诊断，之后通过CT和超声内镜检查进行分期。手术是胃癌的主要治疗手段，化疗对胃癌可有短时效应。除了病灶局限的患者，胃癌的长期生存率很低。
Etiology of stomach cancer is multifactorial, but Helicobacter pylori plays a significant role. Symptoms include early satiety, obstruction, and bleeding but tend to occur late in the disease. Diagnosis is by endoscopy, followed by CT and endoscopic ultrasonography for staging. Treatment is mainly surgery; chemotherapy may provide a temporary response. Longterm survival is poor except for patients with local disease.
