Testing the Effectiveness of Liquid Biopsies in Detecting Remaining Cancer Cells
測試液體活檢在偵測殘留癌細胞方面的成效
Introduction
Researchers at the Princess Margaret Cancer Centre have started a large clinical study to see if blood-based DNA tests can help find remaining cancer after a patient's primary treatment.
瑪格麗特公主癌症中心的研究人員已啟動一項大型臨床研究，以確認基於血液的 DNA 檢測是否能幫助發現患者在接受初步治療後殘留的癌症。
Main Body
The SHERLOCK trial, funded by a $50-million grant from the Peter Gilgan Foundation, aims to confirm the detection of molecular residual disease. This refers to tiny amounts of tumor DNA that cannot be seen on standard CT scans. By studying 7,000 patients who have received chemotherapy or radiation, the researchers want to determine if a positive blood test means a patient needs new immunotherapy treatments. Conversely, they want to see if a negative result allows patients to stop toxic treatments to avoid harmful side effects.
SHERLOCK 試驗由 Peter Gilgan 基金會資助 5,000 萬美元，旨在確認分子殘留疾病的偵測。這指的是標準 CT 掃描無法看到的極少量腫瘤 DNA。透過研究 7,000 名接受過化療或放療的患者，研究人員希望確定血液檢測結果呈陽性是否意味著患者需要新的免疫治療。
In the past, research into liquid biopsies was often limited to one type of cancer. Therefore, experts from the University of British Columbia emphasize that SHERLOCK's broad focus on many different cancers is a major step forward in collecting medical data. However, because this is an observational study, the results cannot be used in clinics immediately. The study requires a five-year follow-up period to ensure the results accurately predict long-term patient health. Similarly, other projects like the MERIDIAN study have already shown that combining these tests with targeted therapy can help keep patients stable.
相反地，他們希望確認陰性結果是否能讓患者停止使用具毒性的治療，以避免有害的副作用。過去，對液體活檢的研究通常僅限於單一類型的癌症。因此，英屬哥倫比亞大學的專家強調，SHERLOCK 對多種不同癌症的廣泛關注，是收集醫療數據的一個重大進展。然而，由於這是一項觀察性研究，結果無法立即應用於臨床。該研究需要五年的追蹤期，以確保結果能準確預測患者的長期健康狀況。同樣地，其他項目如 MERIDIAN 研究已顯示，將這些檢測與標靶治療相結合有助於維持患者狀態穩定。
Conclusion
The SHERLOCK trial is currently in the observation stage, with the goal of turning liquid biopsies from an experimental method into a standard medical procedure for monitoring cancer recurrence.
SHERLOCK 試驗目前處於觀察階段，目標是將液體活檢從一種實驗方法轉變為監測癌症復發的標準醫療程序。
Vocabulary Learning
🚀 Moving Beyond "And" and "But"
To move from A2 to B2, you must stop using simple connectors. The article uses Logical Signposts—words that tell the reader exactly how two ideas relate.
⚖️ The "Opposite" Logic
Instead of saying "but", look at how the text uses Conversely.
- A2: Some patients need more treatment, but others can stop.
- B2: ...patients need new immunotherapy treatments. Conversely, they want to see if a negative result allows patients to stop...
Coach's Tip: Use Conversely when you are comparing two completely opposite results or situations. It sounds professional and precise.
🔗 The "Cause & Effect" Chain
Notice the word Therefore. It is the B2 version of "so".
- A2: The old research was limited, so this new study is a big step forward.
- B2: ...research into liquid biopsies was often limited... Therefore, experts... emphasize that SHERLOCK's broad focus... is a major step forward.
🖇️ The "Me Too" Connection
When you want to add a similar idea, avoid repeating "also". Use Similarly.
- Example from text: ...the results accurately predict long-term patient health. Similarly, other projects like the MERIDIAN study have already shown...
Quick Reference Guide for your transition:
| A2 Word | B2 Bridge Word | Function |
|---|---|---|
| But | Conversely | Showing a mirror-image opposite |
| So | Therefore | Showing a logical result |
| Also | Similarly | Adding a related point |
Challenge: Next time you write an email or essay, replace one "but", one "so", and one "also" with these academic signposts. This is the fastest way to make your English sound more sophisticated.
