Stathmin-1, Lung Cancer.



Stathmin1 (also known as metablastin) is a major microtubule-depolymerizing protein that involved in cell cycle progression and cell motility.

 Stathmin1 has been found to be up-regulated in some cancers and correlated with cell differentiation and proliferation.  

Stathmin1 is a major cytosolic phosphoprotein that regulates microtubule dynamics and is associated with malignant phenotypes in various cancers, including non-small cell lung cancer.



 To evaluate the role of Immunohistochemical expression of stathmin1 in non-small lung carcinoma and its correlation to different prognostic factors or parameters.


Materials and methods

This retrospective study carried on formalin fixed paraffin embedded surgical specimens of lung tumors  Applying the Immunohistochemical techniques by using the primary antibodies to stathmin1, statistical analysis done and assessment of correlation with different clinical and pathological parameters measured.



Fifty cases of Non-small lung carcinomas that 42% adenocarcinoma,44% squamous cell carcinoma 10% adenosequamous and 4% non-small lung carcinoma 84 % were Stathmin-1 positive.

 No significant correlation between Stathmin-1 expression with age and gender of patients but Stathmin-1 expression were correlated with parameters including type and grade of tumor.

High expression was noted in poorly differentiated tumors.



Measurement of stathmin1 level may be a beneficial prognostic biomarker for non-small lung tumors especially those of poorly differentiated tumors

Stathmin1 expression in non-small cell lung carcinoma significantly correlated with poor tumor differentiation and could be considered as independent prognostic factor.
