Elective Pelvic Nodal Irradiation With a Simultaneous Hypofractionated Integrated Prostate Boost for Localised...

Area of Science:

• Radiation Oncology
• Prostate Cancer Therapeutics
• Clinical Radiation Physics

Background:

• External beam radiotherapy is a standard treatment for localized prostate cancer.
• Hypofractionation offers an alternative to conventional radiotherapy fractionation schedules.
• Elective pelvic nodal irradiation is considered for unfavorable disease due to risk of micrometastatic spread.

Purpose of the Study:

• To review the literature evaluating the simultaneous integrated boost (SIB) technique in prostate cancer radiotherapy.
• To assess the combination of prostate hypofractionation with elective pelvic nodal irradiation within a single plan.

Main Methods:

• Systematic review of published literature.
• Analysis of studies employing the simultaneous integrated boost technique for prostate cancer.
• Evaluation of radiotherapy plans combining prostate and pelvic nodal dose delivery.

Main Results:

• The simultaneous integrated boost (SIB) technique allows concurrent delivery of hypofractionated doses to the prostate and lower doses to pelvic nodes.
• This approach integrates prostate hypofractionation with elective pelvic nodal irradiation in a single plan.
• Literature review focuses on the feasibility and outcomes of this combined approach.

Conclusions:

• The simultaneous integrated boost (SIB) technique represents an elegant method for combining prostate hypofractionation and elective pelvic nodal irradiation.
• Further review of published literature is necessary to fully evaluate the efficacy and safety of this approach in prostate cancer management.
