Guía práctica para el manejo de efectos adversos por inhibidores multicinasas (sorafenib y vandetanib) en pacientes con cáncer de tiroides avanzado

Abstract

The advent of multikinase inhibitors therapy has led to a radical change in the treatment of patients with advanced thyroid carcinoma. The ANMAT (the Argentinian regulatory health agency) has currently approved sorafenib for patients with radioiodine resistant differentiated thyroid carcinoma, and vandetanib for patients with medullary thyroid carcinoma (progressive and/or symptomatic disease). It has been demonstrated by phase iii clinical trials that these drugs improve progression free survival in this group of patients. Although they have a precise indication, an interdisciplinary team in close contact with a committed patient, are required for their effective management.

The adverse events of these drugs are common, but many of them may ameliorate over time, and most of them are manageable, even without the need for dose reduction or drug withdrawal. Knowledge of the correct management of the adverse events is a fundamental tool for the medical team and for the patient to prevent or minimise them, to avoid serious complications and to obtain better patient compliance. The primary objective of this article is to provide a guideline for the diagnosis and treatment of the adverse events produced by the multikinase inhibitors, and to present the initiative of the Hospital de Clinicas in order to implement these guidelines.
