伴癌综合征(Paraneoplastic syndromes)是指恶性肿瘤除转移外所产生的一些外周表现.胃癌也常有各种伴癌综合征,据Hall报告伴癌综合征的发生率为住院各种恶性肿瘤中的20%.有时在胃癌确诊之前,已有一些外周表现,其程度甚至较胃癌病灶所致的更为严重.熟悉和及时识别这类表现有助于早期诊断,从而改善或延长患者的生命.胃癌的伴癌综合征主要表现于下列五个方面:1.内分泌与代谢;2.血液及血管;3.肾脏;4.皮肤;5.神经.内分泌与代谢糖肽类(Glycopeptide)激素包括脑下垂体促卵泡激素、促黄体生成素、促甲状腺素及绒毛膜促性腺激素.每一个糖肽类激素均由α及β链组成,后者有生物学及免疫学活性.有些胃腺癌患者血浆中可测及α及β链或完整的绒毛
Paraneoplastic syndromes refer to peripheral manifestations of malignant tumors other than metastases. Gastric cancer also often has various associated cancerous syndromes. According to Hall, the incidence of associated cancerous syndromes is among hospitalized malignancies. 20%. Sometimes before the diagnosis of gastric cancer, there have been some peripheral manifestations, even worse than those caused by gastric cancer lesions. Familiarity and timely identification of these manifestations are helpful for early diagnosis, thereby improving or prolonging the lives of patients. Gastric cancer associated with cancer syndrome mainly in the following five aspects: 1. Endocrine and metabolism; 2. Blood and blood vessels; 3. Kidney; 4. Skin; 5. Nerve. Endocrine and metabolism Glycopeptide hormones (Glycopeptide) including brain The pituitary gland promotes follicle stimulating hormone, luteinizing hormone, thyrotropin, and chorionic gonadotropin. Each glycopeptide hormone consists of alpha and beta chains, the latter being biologically and immunologically active. Some gastric adenocarcinoma patients have plasma Measurable and alpha and beta chains or intact fluff
