However, the diagnostic accuracy of early gastric cancer (EGC) without lymphatic metastasis has obviously improved with an improvement in the diagnostic technique and due to the accumulation of knowledge on the biological profiles of EG C[10-17]. The D2 lymph node excision was used as a regular operation to treat the EGC previously. But the concept for the EGC without lymphatic metastasis has gradually changed and the less invasive resections has been applied in some cases[18-20]. This study aimed at investigating the risk factors of lymphatic metastasis in EGC in order to find out the proofs for the suitable indications for less invasive operations such as endoscopic mucosal resectioning (EMR), laparoscopic and laparotomic resectioning.展开更多
目的:探讨骨代谢生化指标血清Ⅰ型胶原交联氨基末端肽(N-telopeptide of typeⅠcollagen,NTx)和骨涎酸蛋白(bone sialoprotein,BSP)的检测对肺癌和乳腺癌骨转移的临床意义。方法:选择2006年1月至2006年7月长海医院肿瘤科经病理确诊的肺...目的:探讨骨代谢生化指标血清Ⅰ型胶原交联氨基末端肽(N-telopeptide of typeⅠcollagen,NTx)和骨涎酸蛋白(bone sialoprotein,BSP)的检测对肺癌和乳腺癌骨转移的临床意义。方法:选择2006年1月至2006年7月长海医院肿瘤科经病理确诊的肺癌或乳腺癌患者105例,分为两组,其中骨转移组50例,无骨转移组55例。应用ELISA法检测患者血清NTx和BSP浓度。结果:骨转移组患者血清NTx和BSP水平均明显高于无骨转移组(P<0.01)。NTx诊断骨转移的灵敏度和特异度分别为90.0%和67.3%,BSP诊断骨转移的灵敏度和特异度分别为84.0%和70.9%。临床发生骨相关事件(skeletal related event,SRE)的骨转移患者,血清NTx水平明显高于未发生SRE的骨转移患者(P<0.05)。在6~13个月随访期内,21例患者确诊了新发骨转移;采用Cox比例风险回归模型分析,血清NTx浓度升高提示骨转移发生的相对危险度为1.127;乳腺癌患者血清BSP增高是唯一预测骨转移的危险因素(P<0.05),其相对危险度为1.058。随访期共有33例患者死亡;无论肺癌还是乳腺癌,血清BSP增高患者的累积生存率均明显低于血清BSP正常组(P<0.05)。结论:血清NTx和BSP是诊断肺癌和乳腺癌骨转移的重要参考指标,其水平的增高是预测骨转移发生的高危因素;BSP可能是肺癌和乳腺癌患者独立预后指标。展开更多
