General description

The distinction between high grade cervical intraepithelial neoplasia (CIN2/3) from low grade cervical intraepithelial neoplasia (CIN1) is clinically significant with treatment recommendations linked specificallyto risk of cancer or CIN3 outcome. CIN1 will progress into invasive carcinoma in <1% of cases and is typically managed with Papanicolaou smear follow-up, whereas CIN2/3 has a 5% to 20% risk of progression1 and is usually treated with an excisional procedure (loop electrosurgical excision procedure or cone biopsy).1 Stathmin, also referred to as Stathmin-1 and oncoprotein18, is a ubiquitous microtubule-destabilizing protein shown to be important during mitosis and has been implicated as a regulator of cell motility and migration.

Recent studies show anti-stathmin is positive in 24/82 (29%) CINs with differential expression based on the grade of the lesion as 5/56 (9%) CIN1, 5/11 (45%) CIN2, and 14/15 (93%) CIN3; whereas, anti-p16 staining of the same cases was immuno-reactive in 66/83 (80%) CINs, including 40/56 (71%) CIN1, 11/11 (100%) CIN2, and 15/16 (94%) CIN3. Anti-stathmin shows similar sensitivity for CIN3 to anti-p16 (93% vs 94%) although it drops off for CIN2 (73% vs 96%). The specificity of anti-stathmin for both CIN2/3 (94%) and CIN3 (89%) is higher than that of anti-p16 (44% and 39%, respectively). Anti-Stathmin stains basal layer of normal benign ectocervix. A well-oriented fragment of cervix tissue would increase the accuracy of diagnosis. In conclusion, based on recent studies, anti-stathmin has a higher specificity relative to anti-p16; therefore, anti-stathmin has major potential as a diagnostic marker in CIN classification over anti-p16.

Stathmin is a microtubule-destabilizing phosphoprotein, firstly identified as the downstream target of many signal transduction pathways. Several studies then indicated that stathmin is overexpressed in many types of human malignancies, thus deserving the name of Oncoprotein 18 (Op18). At molecular

Because of the fact that any meaningful classification should bear a close relationship to the biological behavior of the lesions, the usefulness of all new classifications of cervical precancer lesions can only be established by well controlled prospective follow-up studies.
