常见问题及解答

(美国)

 

1.      What is the purpose of the colorectal cancer screening

大肠癌筛查的目的是什么

The purpose of the screening is to detect occult blood (blood not visible to the naked eye), which indicates bleeding in the gastrointestinal tract. Such bleeding may be a symptom of colorectal cancer.
筛查的目的是发现大便中隐秘的血液(肉眼不可见的隐血)。出现隐血表明胃肠道里有出血。这样的出血可能是结直肠癌的一个症状。

 

2.      Who should take this test?

谁应该做这个测试?

The risk of developing colorectal cancer begins to increase after the age of 40 and rises sharply over the age of 50. All persons who do not have a family history of colorectal cancer, a previous history of colon cancer, or any other malignancy, and who have no symptoms, should take the test. All persons in high-risk categories for colorectal cancer should make an appointment with their physician for a colonoscopy. These include:

-        Those who have had colorectal cancer

-        Women who have had breast cancer or reproductive tract cancer

-        Those who have had benign intestinal polyps

-        Those with a parent, sister, or brother who have had colorectal cancer

患结直肠癌的风险从40岁开始上升, 50岁以后患直肠癌的风险则呈急剧上升。事实上,所有那些没有结直肠癌家族史的人群,曾患有结肠癌的患者,或患有任何其他恶性肿瘤的人士以及尚无任何症状的人士都应该进行检测。对于所有处在结直肠癌高风险类别的人士,则应进行直肠镜的检查,这些人士包括:
——
曾患有结直肠癌
——
患有乳腺癌或生殖系统癌症的女性
——
有良性的肠道息肉的人士
——
家族中父母、姐妹或兄弟有结直肠癌的

 

Note: Persons with ulcerative colitis and Crohns disease are at an increased risk of developing colorectal cancer; however, different screening methods should be used.

:患有溃疡性结肠炎和克罗恩病的病人发展成结直肠癌风险增大,应使用不同的筛选方法进行筛选诊断。

 

3.      How does the screening program work?

这种筛查是如何工作的

The program is based on a simple, take-home test called EZ DETECT, manufactured by BIOMERCA and distributed through CVS/pharmacy.

该筛查方法是一种简单的在可家里操作的检测方法,称为EZ DETECT检测,由BIOMERCA生产,在美国可在CVS 和药房购买到。

 

4.      Is the test difficult or painful?

这种测试方法困难或使用者有痛感吗?

No. This test is user-friendly and requires no stool collection. It includes simple directions for preparing your Test Results Card.

没有。这个测试使用非常简便,可自行操作,同时不需要收集粪便。产品中有简单易懂的使用说明和记录卡来记录您的检测结果。

 

5.      Should I take the test even if I have no symptoms?

即使我没有症状我是否也应该进行测试,

Yes. Most cancers and polyps do not cause pain or other symptoms at the onset but can be detected at an early stage by minute quantities of blood in the stool.

是的。大多数癌症和息肉不会引起疼痛或引起其他症状,但这些不为人察觉的癌症或息肉的早期症状完全可以通过几分钟的简单测试检测出。

 

6.      How will I know if my test is positive?

我怎么知道我的测试是阳性的?

You are responsible for interpreting your test result. Any trace of blue-green color visible on any of the three tests indicates that blood may be present in your stool (a positive test result), meaning that there I a possible condition requiring your physicians attention. If you have a positive test result, you should make appointment with your primary care physician for follow-up care. If you have any symptoms that concern you consult your physician even if your test result is negative. You should be seen within four to six weeks after the test. Your physician may want to run additional tests.

你可以通过观察试纸的颜色变化观察到检测结果。在连续三次检测的任何一张检测试纸上出现蓝绿色,表明大便里含有隐血(检测为阳性结果),这意味你需要去看医生。如果你的连续三次测试有一次出现阳性结果,你应该约见医生进行后续诊断并跟进。如果你有任何症状或担心,即使你的这次测试结果是阴性的,也应咨询你的医生。隐血检测后的46周你应该去咨询你的医生,以确定是否需要额外的检测。

 

7.      If my test is positive, does it mean I have cancer?

如果我的测试是阳性的,是否意味着我患有癌症?

A positive EZ DETECT test means that there may be bleeding in the gastrointestinal tract. Benign conditions such as polyps, hemorrhoids, or rectal fissures can cause bleeding that would cause a positive result. Most studies suggest that only 5 to 10 percent of those with positive tests will be diagnosed as having cancer. However, it is imperative that anyone with a positive test result see a physician as soon as possible to determine the cause of bleeding.

EZ DETECT检测结果是阳性意味着胃肠道有出血。良性息肉等疾病,痔疮或直肠裂缝均可引起出血从而造成检测出现阳性结果。研究表明,多数情况下只有5 - 10%的阳性会最终被诊断为癌症。不管怎样,重要的是,任何一次检测出现阳性结果,你须尽快看医生以确诊出血的原因。

 

8.      If my test is negative, does it mean I dont have cancer?

如果我的测试是阴性的,是否意味着我没有癌症?

Not necessarily. A negative test means that there was no blood detected at the time. Blood in the stool may occur intermittently or not at all. You should still walk to your doctor about additional colorectal cancer screening and prevention methods.

不一定。测试是阴性,仅意味着本次检测未检测到便血。便血发生有间歇性或根本没有便血。所以,你仍然应该向医生咨询是否需要及进行其他方式的结直肠癌的筛查及采取的预防措施。

 

9.      If my test is positive, how should I follow up?

如果我的测试是阳性的,我该怎么做?

You could go see your family doctor or go directly to a gastrointerologist.

你可咨询你的家庭医生或直接到医院咨询消化科医生。

 

10.   What are the chances of survival for someone with colorectal cancer?

如果是结直肠癌,生存的机会是多少?

If the cancer is found early and treated properly, more than 90 percent of patient survive five years or more. Thats why taking this test is so important.

如果是早期发现并进行得当的治疗,超过90%的患者能够存活五年或更长。这也是为什么进行隐血测试是非常重要的。

 


请解释该产品如何进行不同程度判定检测。

 

便隐血检测试纸结果读取参考颜色


人粪便中的血红蛋白浓度决定本产品试纸显示颜色的深浅,随着人血红蛋白浓度的逐渐升高,试纸十字检测区域内显示的颜色依次加深,从无色、浅(或弱)蓝绿色至强蓝绿色。随着人血红蛋白浓度的升高,试纸显示的颜色依次加深是由产品的检验原理决定的。试纸十字检测区域内颜色显示依次为:弱蓝绿色、中等蓝绿色、强蓝绿色,其中浅(弱)蓝绿色包括只有一个蓝绿色小斑点或呈现多个蓝绿色斑点且成不均匀分布的显色情况。在两分钟内,检测试纸十字检测区域内呈现蓝绿色,即使颜色很浅,或成点状、不均匀分布,均为阳性结果。即在十字检测区域内显示的任何可见的蓝绿色均为“阳性”结果。
