Biochemical alterations and paraneoplasic syndromes in patients with renal carcinoma

Abstract

Introduction: Renal carcinoma can show biochemical and paraneoplasic alterations at the moment of its diagnosis. Its diagnosis can be delayed due to these biochemical alterations. About 20 % of patients with renal carcinoma can have paraneoplasic syndromes or biochemical alterations. Method: We reviewed the information of patients treated with nephrectomy for renal cell carcinoma between 2015 and 2022. We analyzed demographic, clinical and oncological variables. We performed a retrospective, descriptive, analytical study. Results: We reviewed 65 files. Prevalence in males was higher with 72.3 %. Age mean was 66 years. Renal cell carcinoma was found in 70 % of patients. 34.4 % presented with anemia, LDH was elevated in 9.5 %. Hypercalcemia presented in 7.8 %. GGT was elevated in 21.4 %. Alcaline phosphatase was elevated in 29.2 %. 13 % showed hipoalbuminemia. Globular sedimentation rate was high in 75 %. Prothrombin time was high in 9.1 %. Neutrophil-lymphocyte ratio (NLR) was high in 33 %. Conclusions: Renal carcinoma is a pathology that can show biochemical alterations and different paraneoplasic syndromes. Diagnosis and management must be individualized. Mexican population shows similar biochemical alterations compared to the data reported in international literature.
