A new blood test may help detect pancreatic cancer in its early stages with up to 97% accuracy, according to a recent study. This test looks for specific genetic markers released by pancreatic cancer cells, offering hope for earlier detection and better survival rates.
Why Early Detection Matters
Pancreatic cancer is one of the deadliest cancers. It is difficult to detect in its early stages because the pancreas is located deep in the abdomen, and its symptoms are often mistaken for other conditions. As a result, most patients are diagnosed only after the cancer has already spread.
The survival rates for pancreatic cancer highlight the importance of early detection:
- If diagnosed at an early stage, before it spreads, the five-year survival rate is 44%.
- If detected after it has spread, the survival rate drops dramatically to just 3%.
Because of this, researchers have been searching for better ways to catch pancreatic cancer before it reaches an advanced stage.
How the Blood Test Works
The new test detects eight small RNA particles and eight larger DNA markers that are released into the bloodstream by pancreatic cancer cells. These genetic markers create a unique cancer signature, allowing doctors to identify the disease with high accuracy.
A smaller study with 95 patients in the U.S. and Japan showed a 98% detection rate. Encouraged by these results, researchers expanded the study to include 523 patients with pancreatic cancer and 461 healthy people from Japan, the U.S., South Korea, and China.
Test Results Across Different Populations
The blood test correctly identified pancreatic cancer in:
- 93% of U.S. participants
- 91% of South Korean participants
- 88% of Chinese participants
To improve accuracy even further, researchers combined this test with CA 19-9, a well-known pancreatic cancer marker that is already used in medical screenings. The combination of both tests detected 97% of stage 1 and 2 pancreatic cancers among U.S. participants.
What This Means for the Future
If this blood test is proven to be effective in further studies, it could revolutionize pancreatic cancer detection. Unlike invasive procedures like biopsies or imaging scans, a simple blood test could help doctors diagnose the disease much earlier, giving patients a better chance at survival.
However, researchers caution that more studies are needed before this test can be widely used. The findings will be presented at a medical conference, but they have not yet been published in a peer-reviewed journal.
Still, the results are promising, and experts hope that with further validation, this blood test could become a powerful tool in catching pancreatic cancer early and saving lives.
