Patients with gastric cancer who have left supraclavicular lymph node metastasis, which is a distant metastasis, are not suitable for radical resection surgery in this case, but they can choose systemic intravenous chemotherapy, which can control the development rate of tumor, and patients in this period can survive for six months to one year. In the later stage, if there is obvious extensive abdominal metastasis and swallowing difficulty, deep vein nutrition support treatment can be performed or choose jejunostomy for strict enteral nutrition, which can improve the patient’s quality of life and achieve the purpose of prolonging the survival period in the later stage. If patients with gastric cancer have metastasis of regional lymph nodes in the abdominal cavity, they can choose radical surgery, and the survival time ranges from 1-3 years, and even some patients can survive longer.
