ABSTRACT
BACKGROUND: Soft tissue sarcomas (STS) have a high risk of relapse in spite of the use of (neo)adjuvant chemotherapy. In this context, looking for new prognostic biomarkers is an interesting field of research. Our aim is to analyze the prognostic impact of neutrophil-to-lymphocyte ratio (NLR) and other serum markers in patients with STS who received chemotherapy with curative intent. MATERIALS AND METHODS: This is a retrospective observational study. We included all patients with STS (primary tumor, local recurrence or resected metastatic disease) treated with high-dose ifosfamide and epirubicin with curative intent from January 2007 to December 2018. The pretreatment NLR and other serum markers were calculated, selecting the median as the cut-off value for the survival and multivariate analysis. RESULTS: Seventy-nine patients were included. Median NLR, platelet-to-lymphocyte ratio (PLR) and lymphocyte-to-monocyte ratio (LMR) were 2.83, 174.05 and 3.25, respectively. Median progression-free survival (PFS) was significantly longer in patients with low NLR [not reached (NR) vs 21, 92 months, P < 0.01]. No significant differences were found for PFS regarding PLR or LMR. For overall survival (OS), a significant survival advantage was also found for patients with low NLR (NR vs 65.45 months, P = 0.01), without differences for PLR or LMR. In multivariate analysis, NLR remains an independent prognostic factor for PFS. CONCLUSION: In our cohort, low NLR was significantly associated with a longer PFS and OS, and is consolidated as an independent prognostic factor.

Chordomas are tumors with a bad prognosis, because of their location, local aggressiveness and high rate of local relapse. Despite of be benign tumors, they have certain capacity of metastasize and a clinical evolution that results interesting. When we analyzed our series with 35 chordomas studied and treated between 1975 and 2002, we found three patients that experienced a systemic dissemination (AU)
