OBJECTIVE: Behaviors of @entity418 are different according to the geographic distribution. The prevalence of bone @entity236 in @entity1 with @entity418 has been shown to be between 40% and 90%, but clinical correlation is unknown. The aim of this study is to determine the rate of bone @entity236 in @entity1 with @entity418 in the northeast of Iran and its relationship with clinicopathologic findings of the @entity5 . METHODS: A total of 43 @entity1 with @entity418 , who were candidates for esophagectomy (without neo-adjuvant chemotherapy), were enrolled in this study from 2007 to 2009. Bone marrow samples derived from rib bone were stained with @entity1710 and @entity1711 (H_E) to distinguish tumoral cells, and cytokeratin immunohistochemistry (CKIHC) was used to determine micrometastasis. The correlation of the results was studied with the histopathologic indices of @entity5 ( @entity5 ( @entity5 ), N (node) and length of tumoral involvement and grading) as well as characteristics of the @entity1 (sex and age). RESULTS: The mean age was 64 (57-70) years and the M/F ratio was 2.9. As many as 38 @entity1 (88.4%) had @entity957 and five @entity1 (11.6%) had @entity420 . In nine cases (20.9%), the H_E test, and, in 13 cases (30.2%), the CKIHC evaluation was positive. Statistically, there was no relationship between the pathologic type and the stage of @entity5 with the H_E study and CKIHC test, respectively. On the other hand, a significant meaningful correlation was found between microscopic bone @entity236 as well as mediastinal lymph node involvement and grade of the @entity5 . CONCLUSION: Bone @entity236 incidence was low in our geographic area. According to our study, bone @entity236 in @entity418 is related to differentiation grade and mediastinal lymph node involvement.
