Özet

Background: Low expression of p27, a cyclin-dependent kinase inhibitor, has recently been reported to be associated with poor prognosis of many tumors. Moreover, an inverse relationship between p27 expression and proliferation was also noted. Although accumulating data indicate a correlation between high proliferation rate and aggressive behavior of gastrointestinal stromal tumors, no conclusive correlation between p27 expression and either tumor recurrence or proliferation has been established yet in this disease. The aim of this study was to immunohistochemically investigate the association of p27 expression (as measured by the p27 labeling index: p27L1) with recurrence and proliferation (as measured by the Ki-67 labeling index: KLI) in gastrointestinal stromal tumors.
