Advanced Hepatocellular Cancer Treated with Sorafenib and Novel Inflammatory Markers.

objectiveHepatocellular cancer (HCC) is an aggressive tumor with an increasing incidence in recent years. Life expectancy is limited, especially due to limited effective treatments and tumor biology. In this study, we aimed to examine the effect of neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), prognostic nutritional index (PNI) parameters of treatment efficacy of patients using sorafenib in primary systemic therapy, progression-free survival (PFS), and overall survival (OS). MATERIALS AND

methodsIn this study, we retrospectively analyzed 78 patients who used sorafenib as a first-line systemic treatment. NLR, PLR, and PNI values were calculated with the existing formulas. Cut-off values for these markers were determined by performing ROC curve analysis. These values were determined respectively as 2.88, 111.05, and 38.25. Patients were divided into two groups according to this threshold value. OS and PFS values were calculated using a Cox proportional risk model. The effects of markers on OS and PFS were examined based on the cut-off value.

resultsThe mean PFS was 7.1 (range 1-46) months, and the mean OS was 14.1 (range 1.5-94) months. The pre-treatment decreased NLR (< 2.88) value was prognostic for higher PFS and OS rates. These values were determined respectively as 9.23 ± 1.79 and 3.45 ± 0.32 months for PFS and 21.17 ± 4.53 and 5.32 ± 0.53 months for OS. Pre-treatment decreased PLR (< 111.05) was found to be a positively significant prognostic value for both survival. These values were determined respectively as 7.37 ± 1.43 months and 3.16 ± 0.47 months for PFS and 21.12 ± 5.52 months and 6.16 ± 0.87 months for OS. And also, low PNI (< 38.25) value was prognostic for lower PFS and rates. These values were determined respectively as 7.47 ± 0.59 months and 3.25 ± 0.21 months for PFS and 16.36 ± 4.37 months and 5.15 ± 0.42 for OS. All three parameters were found to be statistically significant (p < 0.05) for both OS and PFS as independent prognostic markers.

conclusionToday, as the standard first-line treatment of HCC has shifted to combinations with immunotherapy (IO), IO transportation is not possible in most countries of the world. However, there are also patients who achieve great survival with only sorafenib. The important point is to identify the biomarkers that predict which patient will benefit better from which treatment. With the markers in our study and a scoring system that can be obtained with these markers, it can be evaluated which patient will be given IO combination and which patient will be given only TKI treatment. We think that such a scoring system can be used to identify suitable patients, especially in countries where, for financial reasons, not every patient can access Immunotherapy. The advantage of these tests is that they are inexpensive, easily calculable and standardized.
