[Targeted therapies and radiotherapy]

Area of Science:

• Oncology
• Radiation Oncology
• Molecular Targeted Therapy

Background:

• Targeted therapies are a major focus of cancer research, often exhibiting cytostatic effects.
• Combining targeted therapies with conventional treatments like radiotherapy is a logical strategy.

Purpose of the Study:

• To review experimental data on the interactions between radiotherapy and various targeted therapies.
• To discuss potential mechanisms underlying these interactions.
• To evaluate preliminary clinical findings.

Main Methods:

• Review of experimental data on interactions between radiation and targeted therapies.
• Discussion of proposed mechanisms of interaction.
• Analysis of preliminary clinical results.

Main Results:

• Extensive experimental data exist on interactions between radiation and EGF-receptor inhibitors, antiangiogenic therapies, farnesyltransferase inhibitors, and cell cycle inhibitors.
• Preliminary clinical results suggest a promising outlook for combined approaches.

Conclusions:

• The combination of radiotherapy and targeted therapies, especially EGFR pathway inhibitors and anti-vascular treatments, is a promising strategy.
• Continuation and intensification of clinical trials are necessary to validate this approach.
