Why timing is everything
Currently, doctors often remove many lymph nodes just to be safe. This can cause more pain and longer recovery times. But removing too many healthy nodes can hurt your body.
They need a way to know for sure during the operation. Old methods relied on waiting days for lab results. Surgeons had to guess based on what they saw.
The surprising shift
Old methods relied on waiting days for lab results. Surgeons had to guess based on what they saw. This meant some patients got too much surgery. Others might have missed hidden cancer cells.
Now, a new technique offers answers in minutes. It changes how doctors plan the final steps of the cut. This shift could save patients from unnecessary pain.
Think of this test like a security scanner at an airport. It checks bags quickly to find dangerous items. Here, the scanner looks at lymph nodes in real time.
The team used a method called frozen section analysis. They freeze the tissue and cut it very thin. Then they look at it under a microscope immediately.
Researchers looked at data from 238 patients at one hospital. These patients had early stomach cancer and lymph node surgery. The team tracked how often the test worked correctly.
They also checked if cancer was hiding in other nodes. The study focused on early stages of the disease. This ensures the results apply to similar cases.
The test worked very well for finding big clusters of cancer. In most cases, it matched the final lab results perfectly. However, small clusters of cells were sometimes missed.
These small clusters did not come back during follow-up. When the test said cancer was present, it was right most of the time. But if the test said no cancer, there was still a small risk.
This doesn’t mean this treatment is available yet.
About 8 out of 100 patients had hidden cancer elsewhere. This helps doctors decide if they need to cut more. It balances safety with quality of life for the patient.
Experts say this is a step forward for precision medicine. It allows surgeons to be more careful with healthy tissue. It helps reduce the chance of cancer returning later.
If you are facing stomach cancer surgery, ask your doctor about this. It might not be ready for every hospital right now. You should discuss if this test fits your specific case.
This study looked at past data from one location. It did not test every type of stomach cancer. Some rare cases might not show up on this test.
Larger studies are needed to confirm these results. The sample size was decent but not huge. We need more data to be fully sure.
Doctors will run more trials to make this standard. They want to ensure it works for everyone, not just some. Approval from health agencies will take time and careful review.
