Endoscopic ultrasound – trauma means lowest detection of lung cancer

Endoscopic ultrasound is a trauma lowest means of detecting lung cancer — the top by a probe with a camera can be inserted into the esophagus, the security of the judgment accurately lung masses of benign and malignant scenario.

United States, Duke University Medical Center in Gastroenterology experts in assessment of the 18 cases of endoscopic ultrasonography results concluded: endoscopic ultrasound should be considered as an evaluation of suspected malignant breast tumors of conventional detection methods.

The researchers reported that if the endoscopic ultrasonography can be widely used clinically, nearly one-third of patients with suspected lung cancer will no longer need to carry out other trauma more checks to determine the status of cancer, as well as of good and evil by stages.

Lung cancer treatment success lies in the correct identification of the tumor and whether it has been transferred.

Use of endoscopic ultrasonography as a check, the doctor can sometimes see the masses, directly and more importantly, the doctor can check extraction by endoscopy in patients with tumor tissue samples, and through the sample to determine whether the cancer has been transferred to the nearby tissue or lymph nodes. The pathologist can rapidly through the sample to determine whether the tumor is malignant.

The research results were published in February 2007 the journal Chest.

The research group of Dr. Frank Gress, a member of the analysis results can be changed for certain types of lung cancer staging method.

The study used meta-analysis (meta-analysis) method---researchers brought together 18 small clinical trial data, these small clinical trials to evaluate whether the endoscopic ultrasound can accurately detect 1201 non-small cell lung cancer patients of cancer spread.

Lung cancer patients in approximately 80% are non-small cell lung cancer, lung cancer spread rapidly.

The researchers found that endoscopic ultrasound can effectively detect 83% no chest lymph node metastasis of cancer as well as identify 97% have lymph node metastasis of cancer.

Gress, if clinically used endoscopic ultrasound, about 30% of all lung cancer patients do not have to accept more trauma more checks.

In these invasive examination, and some even require patients to receive general anesthesia for surgery doctor through the operation of extraction from their lungs method of tissue samples.

Currently, researchers are working to assess the cost effectiveness of endoscopic ultrasound.
