Abstract

Merkel cell carcinoma (MCC) is a neuroendocrine skin cancer with a higher propensity for recurrence and metastasis than melanoma or squamous cell carcinoma. Despite aggressive behavior and the tripling of its reported incidence in the past 20 years, there is extensive confusion about how MCC should be managed. Here we address two issues that have impeded optimal MCC management: lack of a consensus staging system and lack of unique diagnostic codes for MCC. Five conflicting systems currently used to stage MCC will be replaced by one system in 2010 that will diminish confusion about prognosis and management among physicians and patients. The diagnostic bundling of MCC with numerous less aggressive skin cancers leads to care refusals by insurance and an inability to track MCC care costs. Worldwide adoption in 2009 of specific diagnostic codes for MCC will also improve understanding and management of this often-lethal skin cancer.

Key words:
Merkel cell carcinoma

Resumen

El carcinoma de células de Merkel (CCM) es una neoplasia cutánea neuroendocrina con una mayor propensión para desarrollar recurrencias y metástasis que el melanoma o el carcinoma epidermoide. A pesar de su comportamiento agresivo, y el hecho de que su incidencia se haya triplicado en los últimos 20 años, aún existe una gran confusión respecto al tratamiento del CCM. En esta revisión abordaremos dos cuestiones que han dificultado el tratamiento óptimo del CCM: la carencia de un sistema de estadificación consensuado y la falta de códigos diagnósticos exclusivos para el CCM. Los 5 sistemas contradictorios que actualmente se utilizan para estadificar el CCM serán reemplazados solamente por uno en 2010, lo que disminuirá la confusión sobre el pronóstico y el tratamiento entre los médicos y pacientes. La codificación diagnóstica del CCM, junto con numerosas neoplasias cutáneas menos agresivas, ha condicionado la denegación de atención por parte de las compañías aseguradoras y la incapacidad para evaluar los costes de la atención sanitaria por CCM.

La adopción, que se ha efectuado en 2009, de códigos diagnósticos específicos para el CCM también mejorará la comprensión y el tratamiento de esta neoplasia cutánea frecuentemente letal.
