Circulating Tumour Cell Liquid Biopsy肿瘤捕手液体活检技术
肿瘤捕手液体活检技术Circulating Tumour Cell Liquid Biopsy
A circulating tumour cell test looks for tumour-derived cells in a blood sample. This differs from tests that analyse cell-free tumour DNA. Both may be called liquid biopsy, but the analyte, assay and validated clinical purpose must be specified.循环肿瘤细胞检测在血液样本中寻找来源于肿瘤的细胞，与分析游离肿瘤DNA的检测不同。两者都可能被称为液体活检，但需明确检测对象、方法和经验证用途。

What to clarify
How assessment and planning work评估与规划如何进行
A useful laboratory report states what was measured, the result and limitations. Ask whether it is intended for an existing cancer, monitoring or another specific question, and how it will be interpreted with imaging and tissue findings.有用的报告需说明测量对象、结果及局限。应明确用于既有肿瘤、监测还是其他问题，以及如何结合影像和组织结果解释。
Before your consultation
The proposed assay, reason for testing, cancer history, pathology and recent imaging.检测方法、目的、肿瘤史、病理及近期影像。
Send existing records for an initial discussion. Do not arrange new tests, change medication or book non-refundable travel solely from this page. The receiving team should state which additional information is actually needed.初步沟通可使用已有资料，不应仅凭本页安排新检查、改变用药或预订不可退款的行程。接诊团队应说明确实需要补充的资料。
Evidence and limitations
A negative result cannot be assumed to exclude cancer and a detected signal needs clinical interpretation. This is a diagnostic inquiry, not a cancer treatment. Additional testing should follow the clinician’s assessment.不能认为阴性结果排除癌症，检测到信号也需要临床解释。这是诊断咨询而非癌症治疗，后续检查应基于医生评估。
Questions to ask
Can a circulating-tumour-cell result diagnose cancer?循环肿瘤细胞检测能确诊癌症吗？
This is a laboratory investigation, not a treatment. Ask what the test is validated to measure and how its result would change care. Results need interpretation with the clinical history, imaging and tissue findings where appropriate.这是检验而不是治疗。应明确验证用途及结果如何影响护理，结合病史、影像和必要时的组织病理进行解释。
What should be included in my written treatment plan?书面诊疗方案应包括什么？
The treating team should identify the proposed intervention, alternatives, relevant uncertainty, clinical eligibility, anticipated visits, monitoring and arrangements if the plan changes after assessment. Ask who is responsible for follow-up after you return home.诊疗团队应明确拟议干预、替代方案、相关不确定性、适用条件、预计就诊次数、监测安排及评估后调整方案的处理方式，并说明回国后的随访负责人。
Price and quotation
Ask for an itemized provider quotation after the clinical team reviews your records. The scope may depend on the exact intervention, investigations, consumables, admission and monitoring. Confirm currency, validity period and what happens if the plan changes. Medical fees are paid directly to the provider; Uwell coordination is separate.临床团队审核资料后，可索取机构的分项报价。费用范围可能取决于具体干预、检查、耗材、住院和监测。应确认币种、有效期及方案调整后的计费方式。医疗费用直接向提供机构支付，优健云协调服务另行计费。
