**Author details**

The cut-offs for NLR and PLR show significant variability. Mostly, the cut-off levels are identified either based on ROC analysis and Youden Index, or the median is selected for cut-off.

Combined scores appear, based on SIR data in complex with patient's characteristics as well as tumour features. The informativity of such scores is generally higher than that of separate components; therefore, wider testing of these scores in different populations should be neces-

M Presence or absence of distant metastases in accordance with TNM classification

N Status of regional lymph nodes regarding metastases in accordance with TNM

Less frequently, the 75th percentile is applied.
