SIGNORE, Alberto et al. Molecular imaging of cancer microenvironment. Nucleus [online]. 2016, n.60, pp. 18-23. ISSN 2075-5635.

In the last decades, researchers have been focusing on cancer cells looking for novel targets, however, tumours grow in a host environment that either contribute to or inhibit tumour expansion and metastatization. Several efforts have been focused on cancer microenvironment for diagnostic and therapeutic purposes. Nuclear medicine can contribute to understand the complexity and role of tumour microenvironment by imaging several of its components (chemokine receptors, immune cells, stromal antigens, vascular factors, etc). In a tumour, each microenvironment component offers many potential targets for several drugs or radiopharmaceuticals. Cancer may be studied using different strategies from different viewpoints: imaging tumour markers or differentiating markers for diagnostic purposes in order to plan personalized therapies (receptor agonists or superagonists); imaging tumour stroma and vascularization to monitor cell adhesion, metastases, angiogenesis and hypoxia; imaging the host response of cancer cells to monitor efficacy of immunotherapeutic strategies
