Abstract

Objective: The objective of our present study was to assess the role of serum amyloid A (SAA) in stages and prognosis of renal cell carcinoma. Material and Methods: It was a hospital based retrospective study carried out in the Department of Medicine and Biochemistry of Manipal Teaching Hospital, Pokhara, Nepal between $1^{st}$ January 2008 and $31^{st}$ December 2011. The variables collected were SAA, CRP. Approval for the study was obtained from the institutional research ethical committee. Quantitative analysis of human SAA and C-reactive protein (CRP) was performed by radial immune diffusion (RID) assay for all cases. Results: Of the 422 total cases of renal cell carcinoma, 218 patients had normal and 204 abnormal SAA. SAA levels were grossly elevated in T3 stage ($122.3{\pm}SD35.7$) when compared to the mean for the T2 stage ($84.2{\pm}SD24.4$) (p value: 0.0001). Similarly, SAA levels were grossly elevated in M1 stage ($190.0{\pm}SD12.7$) when compared to the M0 stage ($160.9{\pm}SD24.8$) (p: 0.0001). There was no significant association with elevated CRP levels ($209.1{\pm}SD22.7$, normal $199.0{\pm}SD19.5$). Conclusion: The validity of SAA in serum as being of independent prognostic significance in RCC was demonstrated with higher levels in advanced stage disease.
