HALP Score as a New Prognostic Index in Metastatic Renal Cell Cancer.

Objective: To evaluate prognostic significance of the new index, designed by formulating hemoglobin, albumin, lymphocyte, and platelet (HALP) counts in patients with metastatic renal cell carcinoma (RCC).

Study Design: Descriptive study.

Place And Duration Of Study: Department of Medical Oncology, Celal Bayar University, Manisa, Turkey and Adnan Menderes University, Aydin, Turkey, from January 2014 to April 2020.

Methodology: Patients with metastatic RCC and sufficient follow-up data were included in the study as a retrospective cohort. HALP score was calculated as hemoglobin (g/L) × albumin (g/L) levels × lymphocyte count (/L)/platelet count (/L). The cut-off value was determined by examining the area under the ROC curve for the HALP value. The endpoints of this study included overall survival (OS) and progression-free survival (PFS).

Results: The mean overall survival (OS) of the patients with low HALP score was 17.7 months (95% CI, 2.21 - 33.18), while the OS of the patients with high HALP score was 89.7 months (95% CI, 55.62 - 123.77) and reached statistical significance (p=0.001). The results of univariate (p = 0.009) and multivariate (p=0.012) analyses were statistically significant as well.

Conclusion: The HALP score in metastatic RCC patients was closely related to the prognosis. Worse OS was found in patients with a low HALP score. Key Words: HALP score, Overall survival, Progression-free survival, Renal cell carcinoma.
