9 Factors for Consideration in Adjuvant Treatment Decisions
Data Risk-benefit Thickness Disease stage/risk of recurrence Patient wishes Ulceration The decision about whether and how to treat in the adjuvant setting should take into account a variety of factors. These factors should be carefully considered and discussed with the patient1 Factors for consideration include The likely risk of a patient’s disease recurring and the parameters that predict for recurrence (melanoma thickness, presence of ulceration, and regional and distant metastatic burden)2 The risk-benefit of potential treatments1 The availability of treatments for advanced disease that have been demonstrated to improve OS2 The patient’s wishes1 References Garbe C, Peris K, Hauschild A, et al; European Dermatology Forum (EDF); European Association of Dermato-Oncology (EADO); European Organisation for Research and Treatment of Cancer (EORTC).

27 Conclusions Fin de la era del tratamiento con Interferón y con Ipilimumab en el contexto adyuvante. La linfadenectomía no debería ser un estándar para todos los pacientes N+. Los tratamientos activos en el melanoma en estadio IV presentan una traducción directa de su eficacia en el contexto adyuvante. Nivolumab durante 1 año de tratamiento, ha demostrado una reducción estadísticamente significativa del riesgo de recidiva en pacientes N+ BRAF wt y mutados en estadios III y en estadio IV resecado, con un perfil de efectos adversos favorable y manejable. Existe una gran necesidad de biomarcadores que ayuden a identificar aquellos pacientes de alto riesgo que realmente precisen tratamientos complementarios.
