ABSTRACT
In the last decade, there has been remarkable progress in research toward understanding and refining the hallmarks of cancer. In this review, we propose a new hallmark - "pro-survival autophagy." The importance of pro-survival autophagy is well established in tumorigenesis, as it is related to multiple steps in cancer progression and vital for some cancers. Autophagy is a potential anti-cancer therapeutic target. For this reason, autophagy is a good candidate as a new hallmark of cancer. We describe two enabling characteristics that play a major role in enabling cells to acquire the hallmarks of cancer - "tumor-promoting microenvironment and macroenvironment" and "cancer epigenetics, genome instability and mutation." We also discuss the recent updates, therapeutic and prognostic implications of the eight hallmarks of cancer described by Hanahan et al. in 2011. Understanding these hallmarks and enabling characteristics is key not only to developing new ways to treat cancer efficiently but also to exploring options to overcome cancer resistance to treatment.
ABSTRACT
In recent years, new therapeutic strategies for non-small cell lung cancer (NSCLC) have been developed, stemming from a better understanding of oncogenic signaling pathways. The analysis of the alterations of genes involved in NSCLC oncogenesis is now an integral part of the diagnostic approach and opens the way to so-called "targeted" therapies. In this article, we will share the latest therapeutic advances by focusing on alterations of HER2, MET, EGFR and KRAS genes, for which new dedicated treatments have become available.
Au cours de ces dernières années, de nouvelles stratégies thérapeutiques pour le cancer du poumon non à petites cellules (CPNPC) se sont développées, découlant d'une meilleure compréhension des voies de signalisation oncogéniques. L'analyse des altérations de gènes impliqués dans le développement de ce sous-type de maladie oncologique fait désormais partie intégrante de la démarche diagnostique et ouvre la voie à des thérapies dites « ciblées ¼. Nous partagerons dans cet article les dernières avancées thérapeutiques en nous intéressant aux altérations des gènes HER2, MET, EGFR et KRAS, pour lesquelles de nouveaux traitements dédiés sont disponibles.
