家庭检测上线:助力降低肠癌筛查年龄
新西兰卫生部长 Simeon Brown 表示,一项全国推广的居家检测(home test)将帮助更多新西兰人更快评估肠道症状,同时释放专科医疗资源,从而推动逐步降低肠癌筛查年龄。
这项检测属于“有症状人群的 FIT(粪便免疫化学检测)路径”,具有以下作用:
- 为有肠癌症状的人提供简单居家检测
- 优先安排真正需要结肠镜检查的患者
- 释放结肠镜资源,从而支持进一步下调筛查年龄
Brown表示:“政府致力于尽快将筛查年龄降至与澳大利亚一致,因为早发现肠癌可以挽救生命。筛查年龄已经从60岁降至58岁,全国范围内,并将从9月起进一步降至56岁,这将在四年内让超过20万新西兰人获得免费筛查资格。”
他表示政府将继续推进筛查年龄下降,而新检测工具是关键组成部分。
关键问题:结肠镜容量
他指出,降低筛查年龄的关键在于医疗系统是否有足够的结肠镜(colonoscopy)处理能力。
“每次降低年龄,都会增加筛查人群和随访需求,结肠镜是系统中最难扩展的部分之一,需要专科医生、手术室时间和设备支持。”
因此政府采取两种方式提升能力:
- 直接增加结肠镜与诊断能力投资
- 更有效利用现有资源,而新检测正属于后者
新检测如何运作
该检测正式名称为 FIT(症状路径粪便免疫化学检测)。患者在家中采集粪便样本,检测是否含有肉眼不可见的血迹,这是肠癌早期的重要警示信号。
它与现有筛查测试原理相同,但针对“有症状患者”进行了调整,更为敏感,以便更早识别风险。
过去,有症状患者通常会直接进入结肠镜等待名单,而现在:
- 多数GP转诊患者将先进行该居家检测
- 几天内即可获得结果
- 阳性患者将优先安排结肠镜或其他检查
Health New Zealand 预计,该路径可减少约30%的结肠镜转诊压力。
医疗影响
Brown表示,这将显著释放专科资源,使真正需要结肠镜检查的患者更快得到治疗,同时缩短等待时间。
他强调:“这释放出的能力,正是我们能够安全降低筛查年龄的关键。”
他也呼吁公众重视肠癌症状:
“如果感觉不对,不要等待,尽快就医。早发现意味着更高治愈率,而这项检测正是为了实现这一点。”
A home test rolling out nationwide will mean more New Zealanders can get faster assessment of bowel symptoms, while also helping free up specialist capacity needed to safely bring down the bowel screening age, Health Minister Simeon Brown says.
Simple home test for people with bowel cancer symptoms (FIT for Symptomatic pathway)
Prioritises colonoscopies for those who need it most
Unlocks colonoscopy capacity, supporting further bowel screening age reductions
“The Government is committed to lowering the screening age as fast as we can to match Australia, because catching bowel cancer earlier saves lives. It’s already come down from 60 to 58 nationwide, and from September it begins to drop to 56 – making more than 200,000 additional New Zealanders eligible for free screening over four years.
“We will keep going, and this new test is a key part of delivering that.”
The key to lowering the screening age quickly is ensuring colonoscopy capacity can keep up.
“Every time the age is lowered, more people become eligible, more results need follow-up, and more colonoscopies are required. Colonoscopies are the hardest part of the system to scale – each one needs a trained specialist, theatre time, and equipment.
“To keep lowering the age, capacity has to be built at every step of the pathway, and we’re doing that in two ways.
“The first is direct investment in more diagnostic capacity, including additional colonoscopies, so more patients can be seen sooner.
“The second is better use of existing capacity – and that’s where the new test, rolling out nationwide from today, comes in. It helps identify who needs a colonoscopy, so we can prioritise those patients and keep reducing waiting times.”
Known officially as the FIT (faecal immunochemical test) for symptomatic pathway, the simple home test checks a stool sample for hidden traces of blood, an early warning sign of bowel cancer.
It is the same physical test already used in the screening programme and works in exactly the same way. The difference is that, because these patients already have symptoms, it is set to be more sensitive – flagging a positive result at lower levels of blood. This means people with symptoms can be assessed quickly to determine whether they have a high risk of a serious bowel condition.
“Until now, many patients with bowel cancer symptoms have been referred for a colonoscopy, meaning they go on a wait list. This simple home test changes that, giving fast, reliable results within a few days of being returned, which helps clinicians prioritise care. Patients who need urgent investigation can be seen for a colonoscopy sooner.”
Under the pathway, most patients referred by their GP to hospital with bowel cancer symptoms will be offered the test first. It is available to people aged 18 and over. Those with a positive result will be prioritised for a colonoscopy or an alternative bowel investigation.
Health New Zealand expects the test to reduce colonoscopy referrals for people with bowel cancer symptoms by up to 30 per cent.
“That’s a significant amount of specialist capacity freed up, allowing people who need a colonoscopy to be seen faster, and reducing wait times. That freed-up capacity is what allows us to keep safely lowering the screening age.”
Mr Brown is encouraging New Zealanders to remain aware of the signs and symptoms of bowel cancer.
“If something doesn’t feel right, don’t wait. See your GP. Finding bowel cancer early gives people the best possible chance of successful treatment, and that’s exactly what this test is designed to support.”
