SARS-CoV-2 infection in patients with melanoma: results of the Spanish Melanoma Group registry.

BACKGROUND: The Spanish Melanoma Group (GEM) developed a national registry of patients with melanoma infected by SARS-CoV-2 ("GRAVID"). METHODS: The main objective was to describe the COVID-19 fatality rate in patients with melanoma throughout the pandemic, as well as to explore the effect of melanoma treatment and tumor stage on the risk of COVID-19 complications. These are the final data of the register, including cases from February 2020 to September 2021. RESULTS: One hundred-fifty cases were registered. Median age was 68 years (range 6-95), 61 (40%) patients were females, and 63 (42%) patients had stage IV. Thirty-nine (26%) were on treatment with immunotherapy, and 17 (11%) with BRAF-MEK inhibitors. COVID-19 was resolved in 119 cases, including 85 (57%) patients cured, 15 (10%) that died due to melanoma, and 20 (13%) that died due to COVID-19. Only age over 60 years, cardiovascular disorders, and diabetes mellitus increased the risk of death due to COVID-19, but not advanced melanoma stage nor melanoma systemic therapies. Three waves have been covered by the register: February-May 2020, August-November 2020, and December 2020-April 2021. The first wave had the highest number of registered cases and COVID-19 mortality. CONCLUSION: Tumor stage or melanoma treatments are non-significant prognostic factors for COVID-19 mortality. During the pandemic in Spain there was a downward trend in the number of patients registered across the waves, as well as in the severity of the infection. GOV IDENTIFIER: NCT04344002.

Analysis of potential risk factors in the survival of patients with primary retroperitoneal liposarcoma / Análisis de los potenciales factores de riesgo en la supervivencia de pacientes con liposarcoma retroperitoneal primario

Introduction: The present work is an observational study of a series of variables regarding overall survival and disease-free survival in patients diagnosed with primary liposarcoma.Methods: The study is prospective with retrolective data collection that includes all patients with primary liposarcoma referred to Hospital Son Espases University Hospital, Palma de Mallorca, Spain from January 1990 to December 2019.Results: The study includes 50 patients and the compartment surgery was performed in 18 patients (36%) of cases. The mean overall survival of the sample was 15.57 years (95% CI: 12.02–19.12) and the mean disease-free survival was 6.70 years (95% CI: 4.50–8.86). Conclusion: Compartment surgery has not shown benefits in terms of overall survival and disease-free survival. The ASA classification (≥3) predicts a poor prognosis in both overall survival and disease-free survival. Resection with free margins, described on the pathological results and defined in this work as R0, show better disease-free survival. (AU)

Introducción: El presente trabajo es un estudio observacional de una serie de variables relacionadas con la supervivencia global y la supervivencia libre de enfermedad en pacientes diagnosticados de liposarcoma primario. Métodos: Este es un estudio prospectivo con recolección de datos retrolectiva que incluye a todos los pacientes con liposarcoma primario remitidos al Hospital Son Espases en Palma de Mallorca, desde enero de 1990 hasta diciembre de 2019. Resultados: El estudio incluye 50 pacientes y la cirugía compartimental se realizó en 18 (36%) de ellos. La supervivencia global media de la muestra fue de 15,57 años (IC 95% 12,02-19,12) y la supervivencia libre de enfermedad media fue de 6,70 años (IC 95% 4,50-8,86). Conclusiones: La cirugía compartimental no ha mostrado beneficios en términos de supervivencia general y supervivencia libre de enfermedad. La clasificación ASA (≥3) predice un mal pronóstico tanto en la supervivencia global como en la supervivencia libre de enfermedad. La resección con márgenes libres, descrita en los resultados patológicos y definida en este trabajo como R0, muestra una mejor supervivencia libre de enfermedad. (AU)
