Transfer of yttrium-90 to breast milk during radiosynoviorthesis of the knee joint
Dear Sir,

Radiosynoviorthesis (RSO) (or radiation synovectomy), which involves intra-articular injection of small radioactive particles, is a well-established therapy in arthritis to treat villonodular synovitis, rheumatoid arthritis and related indications [1, 2, 3, 4]. RSO should only be used when all methods of conservative therapy have failed [5].

Various radioisotopes have been used for RSO, including gold-198, yttrium-90, erbium-169, rhenium-186 and phosphorus-32, but the silicate colloid of yttrium-90 (90Y) is currently preferred [6]. 90Y is a pure beta emitter with a mean/maximum tissue penetration depth of 3.6/11 mm, minimizing the radiation absorbed dose to the non-target tissue. It has a mean half-life of 2.7 days.

After direct injection into the articular cavity, the 90Y colloid particles are phagocytized by macrophages and other inflammatory cells [7]. However, the lymphatic circulation may result in leakage of radionuclides to the locoregional lymph nodes and,...
