What palliative regimen do you use for intra-pelvic recurrence of cervical cancer after definitive chemoRT with T&O brachytherapy?

Based on performance status, expected survival, the time elapsed from previous RT, and volume to treat, have used quad shot to 24-30 in 12 to 15 fraction or salvage HDR interstitial to EQ2 dose of 40 Gy or so.
