Abstract
Introduction

The aim of this study is to identify factors associated to recurrence and survival in primary retroperitoneal liposarcomas.

Methods

Prospective database of 35 patients with primary retroperitoneal liposarcoma treated 2004–2015 were retrospectively analyzed. Exclusion criteria were recurrent and metastatic tumors. Overall survival (OS) and disease-free survival were reviewed. Patient data were compared between patients with or without recurrence within 12 months after surgery. Risk factors were determined using logistic regression analysis.

Results

Five-year OS was 61.1%. One and three-year disease-free survival were 68.6% and 17.1% respectively. OS in the early recurrence group was 36.4 months compared with 43.2 months in the group without early recurrence (P=.011). Early recurrence was associated with a reduction in OS (HR=4.05; CI95%: 1.27–12.96; P=.018). Multifocality and microscopic positive margins R1 were associated with early recurrence. Histologic subtype, margin of resection, histologic grade and multifocality were factors associated with recurrence. Contiguously involved organ resection had a beneficial effect on early recurrence and was associated with an increase in disease-free survival and OS. Adjuvant treatments had no protective effect on recurrence.

Conclusions

This study underlines the crucial role aggressive surgical approach in retroperitoneal Liposarcoma treatment, especially in those patients with histological characteristics that adversely the prognosis.

Resumen
Introducción

El objetivo de este estudio consistió en identificar los factores asociados a la recurrencia y supervivencia del liposarcoma retroperitoneal primario.

Métodos

Se analizó retrospectivamente una base de datos prospectiva de 35 pacientes con liposarcoma retroperitoneal primario tratados quirúrgicamente entre 2004-2015. Los criterios de exclusión fueron tumores recurrentes y metastásicos. Se analizó la supervivencia global (SG) y la supervivencia libre de enfermedad. Los datos de los pacientes se compararon entre los pacientes con o sin recurrencia dentro de los 12 meses posteriores a la cirugía. Los factores de riesgo se determinaron mediante análisis de regresión logística.

Resultados

La SG a los 5 años fue del 61,1%. La supervivencia libre de enfermedad al año y a los 3 años fue del 68,6% al año y del 17,1% respectivamente. La SG en el grupo con recurrencia precoz fue del 36,4% a los 5 años frente al 71,3% en el grupo sin recurrencia precoz (p=0,011). La recurrencia precoz se asoció a una disminución de la SG (HR=4,05; IC95%: 1,27-12,96; p=0,018). La multifocalidad y márgenes quirúrgicos R1 estuvieron asociados a la recurrencia precoz. Los factores asociados a la recurrencia fueron el subtipo histológico, multifocalidad, grado histológico y márgenes quirúrgicos. La cirugía en bloque presentó un efecto protector frente a la recurrencia precoz y estuvo asociada a una mayor supervivencia libre de enfermedad y SG.

Conclusiones

Este estudio pone de manifiesto la importancia del abordaje quirúrgico agresivo en el tratamiento del liposarcoma retroperitoneal, especialmente en aquellos pacientes con características histopatológicas que empobrecen el pronóstico.
