Abstract EN

Rab proteins of the endocytosis and exocytosis pathways both play critical roles in cancer progression, and Rab27B has a significant relationship with several types of human cancer.

However, the association between Rab27B expression and clinical features to determine its clinicopathological significance in gastrointestinal tumor (GIST) has not been investigated.

To examine the expression of Rab27B in GIST and investigate the association between its expression and patient prognosis, immunohistochemistry analysis with tissue microarray was used to evaluate expression of Rab27B in 162 patients with GIST.

The relationship between Rab27B expression and patient prognosis was analyzed.

High nuclear staining of Rab27B was detected in 88 of 162 (54.32%) GIST tissues.

Positive staining of Rab27B was significantly associated with tumor size ( P = 0.006 ), mitotic index ( P = 0.013 ), Armed Forces Institute of Pathology Miettinen risk classification ( P = 0.002 ), and tumor grade ( P = 0.021 ).

Kaplan-Meier survival curves showed that GIST patients with low Rab27B nuclear expression ( P = 0.038 ) and mitotic index <5 per 50 high-power fields ( P = 0.029 ) had a more favorable prognosis.

These findings indicate that Rab27B nuclear expression is correlated with several clinicopathological features of GIST patients, and it may serve as an unfavorable prognostic marker.
