New molecular tools are emerging to identify lung adenocarcinomas during pulmonary resection. The results of a proof-of-concept study suggest that lung cancer fluorescent imaging during surgery using targeted molecular agents may soon be a reality. While the methodology still needs refinement, the technique holds the possibility of precise visualization of tumor margins, detection of other tumors or metastases, localization of small malignant ground glass opacities, and accurate identification of lymph nodes containing metastatic cancer cells.

A new technique that could help surgeons more precisely define the locations of pituitary tumors in near real-time has been demonstrated by a team of scientists. The new strategy uses a visualization technique (matrix-assisted laser desorption/ionization mass spectrometry imaging -- MALDI MSI) that can analyze specific hormones, including growth hormone and prolactin, in tissue.

Scientists found two previously overlooked clues in the health records of 131 children and teens with chest masses. Patients with enlarged lymph nodes in the neck and low levels of certain white blood cells were more likely to have cancer. Masses located in front of the heart were also more likely to be malignant, they report.
