Identifying brain tumors by DMS analysis of diathermy smoke

Ilkka Haapala studied the potential of DMS analysis in brain tumor identifications, showing that DMS can differentiate between tumor types and nontumorous and tumorous tissue. The study has been published in the Journal of Neurosurgery!

A DMS connected to a special smoke sampling system was used to discriminate 7 types of brain tumors and control samples ex vivo in samples from 28 patients who had undergone neurosurgical operations.

In 7-class classification, a classification accuracy of 50 % was achieved, compared to 14 % by chance. Excluding samples preserved in Tissue-Tek improved the classification up to 83 %.
