1. Alpha particles
Alpha particles are central to the efficacy of targeted alpha-particle therapy. These particles, consisting of two protons and two neutrons, possess high energy but limited penetration depth in tissue. This characteristic, while seemingly a limitation, becomes a significant advantage in targeted therapy. The high energy translates to potent cytotoxic effects, causing double-strand DNA breaks within targeted cancer cells, leading to cell death. The limited range, typically only a few cell diameters, confines the damaging effects, sparing surrounding healthy tissue. This contrasts sharply with conventional external beam radiation therapy, which can affect a wider area, including non-cancerous cells, resulting in more pronounced side effects. The distinct properties of alpha particles enable the precise delivery of lethal doses of radiation directly to tumor cells while minimizing collateral damage, a cornerstone of targeted alpha-particle therapy.
This principle is effectively demonstrated in the treatment of metastatic prostate cancer resistant to conventional therapies. Radium-223, an alpha-emitter, mimics calcium and selectively targets bone metastases, delivering localized radiation to the tumor sites. The short path length of the emitted alpha particles restricts the radiation dose almost exclusively to the cancerous bone tissue, sparing the surrounding bone marrow. This targeted approach results in improved survival rates and reduced skeletal complications compared to other systemic treatments. Another application is seen in the development of alpha-emitting radioimmunoconjugates, where alpha-emitting radionuclides are linked to antibodies specifically targeting tumor-associated antigens. These constructs selectively bind to cancer cells, delivering the lethal alpha particle payload directly to the target while minimizing exposure to healthy tissues.
