[New systemic therapies in oncology].

These last decades showed important progress in cancer systemic therapies. A better understanding of the differences between cancer cells and normal cells lead to the emergence of targeted therapies. These treatments interfere with different specific molecules playing a critical role in tumour growth or progression.

[PET contribution in oncology].

Initial workup in oncology relies on histology and extensive staging of disease. Assessment of treatment response is also of paramount importance. Functional imaging with PET provides substantially more information than conventional radiology based on anatomic structures.
