Abstract

According to a modern view, cancer no longer follows a purely mechanistic model. Rather, a tumor is conceived as a more complex structure, composed of cancer cells, the activities of which may interact and reshape the so-called tumor microenvironment (TME), leading to preservation of specific tumoral niches and promoting the survival of tumoral stem cells. Background/Objective: Therapeutic strategies must deal with this unique cancer architecture in the near future by widening their range of activities outside the cancer cells and rewiring a TME to ensure it is hostile to cancer growth. Therefore, an intratumoral therapeutic strategy may open the door to a new type of anticancer activity, one that directly injures the tumoral structure while also eliciting an influence on the TME through local and systemic immunomodulation. This review would like to assess the current situation of intratumoral strategies and their clinical implications. Methods We analyzed data from phase I, II, and III trials, comprehensive reviews and relevant clinical and preclinical research, from robust databases, like PUBMED, EMBASE, Cochrane Library, and clinicaltrials.gov. Results: Intratumoral strategies can be quite variable. It is possible the injection and inhalation of traditional antiblastic agents or immunomodulant agents, or intrapleural administration. Ablation strategy is available, both thermal and photodynamic method. Moreover, TTfields and NPs are analyzed and also brachytherapy is mentioned. Intratumoral therapy can find space in “adjuvant”/perioperative or metastatic settings. Finally, intratumoral strategies allow to synergize their activities with systemic therapies, guaranteeing better local and systemic disease control. Conclusions: Intratumoral strategies are overall promising. Antiblastic/immunomodulant injection and NPs use are especially interesting and intriguing. But, there is generally a lack of phase II and III trials, in particular NPs use need additional experimentation and clinical studies.
