This is the first time that water calorimetry has been successfully used to measure electron beam quality conversion factors for energies as low as 6 MeV (R50=2.25 cm).

Conclusion: Among patients previously treated with definitive EBRT, salvage LDR brachytherapy for localized intra-prostatic recurrence was safe with an acceptable rate of grade 3+ toxicity. Additionally, salvage LDR brachytherapy proved efficacious with 62% of patients remaining disease free at 5 years. Additional patients and longer follow-up are needed to confirm these results.
