MTM Laboratories AG's Cintec(R) P16 Histology Test Increases Accuracy In Diagnosing High Grade Cervical Lesions


2/16/2010 1:35:29 PM

Heidelberg, Germany; February 16, 2010- mtm laboratories, a privately held diagnostics company, today announced the publication of new research showing that CINtec Histology p16 immunostaining significantly increased the accuracy for the diagnosis of high grade cervical lesions. This research is published in the March issue (Volume 133, pp 395-406) of the American Journal of Clinical Pathology (AJCP).

The article by Bergeron and co-authors under the title “Conjunctive p16INK4a Testing Significantly Increases Accuracy in Diagnosing High-Grade Cervical Intraepithelial Neoplasia” shows that CINtec Histology p16 immuno-stained specimens when used in combination with conventional H&E stained cervical specimens, significantly increases the accuracy in diagnosing high grade cervical lesions.

In the study, a Pan-European Trial in Histology, community based pathologists made independent diagnoses on a set of 500 H&E-stained cervical biopsy specimens. Results were compared to a Gold standard established by three gynecological pathology experts as consensus diagnoses. When p16 immunostained slides were added and conjunctively interpreted with the H&E stained slides, a significant increase in diagnostic accuracy for the detection of High Grade Cervical Intraepithelial Neoplasia was observed. Further, there was a significant improvement in inter-observer agreement in the diagnosis of high grade disease.

“CINtec p16 immuno staining delivers a highly reliable and specific stain. The results of this study confirm that the conjunctive interpretation of p16 stained slides could significantly improve the routine interpretation of cervical histopathology” said Dr. Christine Bergeron, Director of the Pathology Department at Laboratoire Cerba in France and lead investigator for this study. “In clinical settings p16 is proving to be invaluable for pathologists for distinguishing between disease and non-disease. Immunostaining of p16 may help to avoid the false positive cases that result in unnecessary treatment. At the same time, screening for p16 will also help avoid false negative cases that may prevent women from receiving treatments to ensure positive outcomes.”

Rüdiger Ridder, the CSO of mtm laboratories, added: "A significant issue exists with the accuracy for making the final diagnosis for cervical disease. Cervical cancer is a preventable disease as long as there is early therapeutic intervention. Tools that increase the accuracy of diagnosis will allow for both reducing missed disease, and avoiding the unnecessary treatment of women. CINtec Histology p16 immuno- staining increases the accuracy and reliability of the diagnosis of high grade pre-cancerous disease.”
