Abstract
INTRODUCTION
Considering the oncological outcomes, understanding the preoperative factors associated with and predicting advanced stage and T3a upstage will help in risk assessment and selection of the right treatment.
MATERIAL AND METHOD
Patients with postoperative pathology of Renal Cell Carcinoma (RCC) and stage T1-2 N0M0 were included in the study. Demographic and pathological characteristics of the patients, Neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), and De Ritis- the ratio of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were recorded. Patients were classified according to T stage (T1-2 vs T3-4) and T3a upstage (T3a upstaged vs non-T3a upstaged).
RESULTS
A total of 289 patients participated in the study when inclusion and exclusion criteria were applied. No difference was found between the groups in terms of age, gender, body mass index, laterality, ABO blood group, Rh positivity and comorbidities. According to multivariate analysis, PLR, AST/ALT, Fuhrman grade, open radical nephrectomy (RN) and Clear Cell pathological subtype were found to be significant-independent factors in predicting advanced stage (T3-4) and T3a upstage (P<0.05).
CONCLUSION
It was found that higher PLR and AST/ALT ratios were associated with more advanced stage and postoperative T3a upstage in RCC patients. In addition, these patients more frequently had open RN and had higher Fuhrman grades, while the clear cell subtype was less common.
