Summary
Radiotherapy is increasingly viable for unresectable hepatocellular carcinoma (HCC) due to advanced techniques. Modern radiation therapy allows higher doses to liver tumors while sparing healthy tissue, improving treatment options for this common cancer.
Area of Science:
- Hepatobiliary Malignancies
- Radiation Oncology
- Medical Physics
Background:
- Hepatocellular carcinoma (HCC) is a globally prevalent and increasing cancer.
- Surgical options like resection or transplant are limited to a few patients.
- Whole liver radiation tolerance historically restricted radiotherapy's role in liver cancer treatment.
Purpose of the Study:
- To evaluate the growing evidence supporting radiotherapy for unresectable HCC.
- To highlight advancements enabling safer and more effective radiation delivery.
- To establish the rationale for randomized trials in HCC radiotherapy.
Main Methods:
- Improvements in 3-dimensional conformal radiotherapy (3D-CRT).
- Advancements in intensity-modulated radiotherapy (IMRT).
- Enhanced understanding of radiation dose-volume effects and toxicity in HCC patients.
Main Results:
- Higher radiation doses can be delivered to focal HCC lesions.
- Reduced radiation dose to noninvolved liver tissue.
- Increased experience and evidence supporting careful use of radiotherapy for unresectable HCC.
Conclusions:
- Modern radiotherapy techniques enhance treatment for unresectable HCC.
- Improved understanding of toxicity allows for safer application of radiation.
- Radiotherapy is a promising option for HCC patients not eligible for surgery.
