[Liposomal boron delivery system for neutron capture therapy].

Area of Science:

• Oncology
• Nanomedicine
• Nuclear Medicine

Background:

• Boron neutron capture therapy (BNCT) is a binary cancer treatment utilizing boron-10 and thermal neutrons.
• Effective BNCT requires high accumulation and selective delivery of boron into tumor tissues.
• Current challenges in BNCT include achieving sufficient and targeted boron delivery.

Purpose of the Study:

• To review the advancements and potential of liposomal boron delivery systems (BDS) for BNCT.
• To highlight how liposomal strategies address the critical need for targeted boron accumulation in tumors.
• To assess the efficacy of BDS in achieving high tumor-to-blood boron ratios.

Main Methods:

• Review of existing literature on liposomal boron delivery systems for BNCT.
• Analysis of strategies involving boron encapsulation in liposomal aqueous cores.
• Examination of methods for accumulating boron within liposomal bilayers.

Main Results:

• Development of various boronated liposomes for BNCT applications.
• Demonstration of significant boron accumulation within tumor tissues using BDS.
• Achievement of high tumor/blood boron concentration ratios, crucial for therapeutic efficacy.

Conclusions:

• Liposomal boron delivery systems represent a promising strategy for enhancing BNCT.
• BDS effectively addresses the challenge of selective boron delivery to tumors.
• Further development of BDS holds significant potential for improving cancer treatment outcomes with BNCT.
