【健康报道】新技术有助于发现胰腺癌 New Technology Helps Find Pancreatic Cancer

Pancreatic cancer is one of the deadliest forms of cancer known.


胰腺癌是已知的最致命的癌症之一。


The disease is hard to detect and is usually found when it has progressed too far to be cured. But researchers are using new technology that might prevent some people from developing the disease.


该病难以发现,通常在病情发展到无法治愈时才发现。但是研究人员正在使用可能阻止某些人患上这种疾病的新技术。


The pancreas is an important organ that produces insulin. Insulin is a hormone that controls the body's blood sugar. The pancreas, however, is hard to see. It is at the back of the abdomen and is covered by the stomach and the liver. That is why doctors have a hard time identifying early tumors during normal physical examinations.


胰腺是产生胰岛素的重要器官。胰岛素是一种控制人体血糖的激素。但是,胰腺很难看到。它在腹部的后部,被胃和肝脏覆盖。这就是为什么医生在正常身体检查期间很难识别早期肿瘤的原因。


Doctor Somashekar Krishna says that is why only 9 percent of patients diagnosed with pancreatic cancer are alive five years after doctors find the disease. Krishna is an endocrinologist, a person who studies hormones and the organs that produce them.


Somashekar Krishna医生说,这就是为什么只有9%的被诊断为胰腺癌的患者在医生发现该病五年后还活着。克里希纳(Krishna)是一名内分泌学家,负责研究激素和产生激素的器官。


"The cancer doesn't produce any symptoms early on," he said.


他说:“癌症不会在早期产生任何症状。”

Patricia Beatty went to the hospital with what she thought was a stomach virus. However, during a scan of her stomach, the doctor found a cyst.


帕特里夏·比蒂(Patricia Beatty)带着她认为的胃病毒去了医院。但是,在对她的胃部进行扫描时,医生发现了一个囊肿。


"He told me that the cyst was there and that it was precancerous," Beatty said.


比蒂说:“他告诉我囊肿在那儿,而且是癌前期的。”


Pancreatic cancer can develop in one of two ways. The disease starts either as a cancerous tumor, or it starts when a cyst becomes cancerous. The difference between a tumor and a cyst is that a tumor is solid, while a cyst is filled with fluid. Cysts on the pancreas are common. Most are not cancerous. Doctors can test fluid from inside the cyst, but it is hard to tell which cysts will develop into cancer.


胰腺癌可以通过两种方式之一发展。该疾病开始于癌性肿瘤,或者开始于囊肿癌变。肿瘤与囊肿的区别在于肿瘤是实体的,而囊肿则充满液体。胰腺上的囊肿很常见。大多数都没有癌变。医生可以从囊肿内部测试体液,但是很难确定哪些囊肿会发展为癌症。


Cancerous tumors or cysts can be identified with special imaging tools. But imaging is so costly that it cannot be used as a usual testing device.


癌性肿瘤或囊肿可通过特殊的成像工具识别。但是成像非常昂贵,以致不能用作常规测试设备。


Krishna led a study of a new device that gives doctors a microscopic look at cysts at the Ohio State University Wexner Medical Center. Krishna says his study showed that the new device is highly accurate.


克里希纳(Krishna)领导了一项新设备的研究,该设备可以使医生在俄亥俄州立大学韦克斯纳医学中心对囊肿进行微观观察。克里希纳说,他的研究表明新设备非常精确。


"We can diagnose cysts with the accuracy of 96% to 97%," he said.


他说:“我们可以以96%至97%的准确度诊断囊肿。”


Krishna and others are training doctors across the U.S. to use this new technology so they can more accurately identify precancerous cysts.


克里希纳(Krishna)等人正在训练全美的医生使用这项新技术,以便他们可以更准确地识别癌前囊肿。


However, doctors will only use the new method after other imaging tests are ordered for another reason. That means the cancer will still grow silently in most people until it is too late to save them.


但是,由于其他原因,医生将在订购其他影像学检查后才使用新方法。这意味着癌症在大多数人中仍然会默默地生长,直到为时已晚挽救他们。


Krishna told VOA that a blood test is the most sensible way to find pancreatic cancer early. But he noted that the test has not been developed yet although researchers continue to work on one.


克里希纳告诉美国之音说,验血是尽早发现胰腺癌的最明智的方法。但他指出,尽管研究人员继续进行这项测试,但尚未开发出该测试。
