Abstract
El cáncer es una de las principales causas de defunción en el mundo, sobre todo en los países en desarrollo. Los antitumorales empleados en la terapéutica presentan una falta de especificidad dada su extensa biodistribución y efectos adversos generados en los tejidos sanos. Con el objetivo de solucionar estos problemas, la nanotecnología ha desarrollado una serie de nanomedicinas (nanopartículas) que consiguen acumular específicamente la cantidad de fármaco administrado en el lugar de acción, logrando así un aumento significativo de la eficacia clínica, junto con una minimización de los problemas de solubilidad, farmacocinéticos, reacciones adversas y resistencias asociadas a los fármacos citostáticos. En esta revisión sistemática, se resumen las estrategias para conseguir la orientación específica de los fármacos antitumorales contra el cáncer, así como los avances más significativos en el diseño y desarrollo de nanopartículas como estrategia terapéutica antitumoral dirigida.

Anti-tumor therapeutic employees have a lack of specificity due to its extensive biodistribution and generated adverse effects on healthy tissues. In order to solve these problems, nanotechnology has developed a series of nanomedicine (nanoparticles) that get specifically accumulate the amount of drug administered at the site of action, thus achieving a significant increase in clinical efficacy, along with a minimization of solubility problems, pharmacokinetic, adverse reactions and resistances associated with cytostatic drugs. In this systematic review summarizes strategies for specific targeting of anticancer drugs against cancer and the most significant advances in the design and development of nanoparticles as targeted antitumor therapeutic strategy.
