[Stereotactic radiation therapy for liver tumours]

Area of Science:

• Oncology
• Radiation Oncology
• Hepatology

Background:

• Liver lesions are common in cancer patients, with traditional focal treatments (surgery, chemoembolization, radiofrequency, systemic therapy) having limitations.
• Previous liver radiotherapy was restricted due to toxicity, primarily used for palliative care or pre-transplant management.
• Localized relapses can occur even after successful focal treatments for liver lesions.

Purpose of the Study:

• To review the indications, results, and techniques of hypofractionated radiotherapy in stereotactic conditions for liver lesions.
• To highlight advancements in high-precision radiotherapy for treating primary and secondary liver tumors.
• To discuss the effectiveness and safety of modern radiotherapy techniques in liver oncology.

Main Methods:

• Utilizing high-precision radiotherapy techniques, specifically hypofractionated radiotherapy delivered under stereotactic conditions.
• Employing minimal margins for precise targeting of liver lesions.
• Reviewing retrospective and prospective studies on hypofractionation for liver lesions.

Main Results:

• Advanced stereotactic hypofractionated radiotherapy allows for higher radiation doses to be delivered to liver lesions.
• This technique significantly reduces the exposure of healthy liver tissue to radiation, enhancing safety.
• Studies demonstrate the effectiveness and safety of hypofractionation for both primary and secondary liver lesions.

Conclusions:

• Stereotactic hypofractionated radiotherapy is an increasingly viable and effective treatment option for liver lesions.
• This approach overcomes limitations of traditional focal treatments and older radiotherapy methods.
• Further research and clinical application of this precise radiotherapy technique are warranted in liver oncology.
