In this patient, Treg cells extended to 53.6 percent of total CD4+ T cells after 14 days, an even that was 20 times as high as the baseline level. Treg cells thereafter stabilized, accounting for about 40 percent of CD4+ T cells during the remainder of the procedure period. Absolute immune-cell counts in the cohort are demonstrated in Figure 2Shape 2Immunologic Effects of eight weeks of Low-Dose Interleukin-2 Therapy and of Extended Therapy.Non-surgical candidates or individuals who refuse surgery will be randomized to either CyberKnife prostate SBRT or conventionally fractionated IMRT. The ultimate objective of the scholarly study is to review the outcomes of CyberKnife prostate SBRT, in terms of efficacy, toxicity and quality of life to da Vinci prostatectomy, manual laparoscopic prostatectomy and fractionated IMRT for early-stage, organ-confined prostate cancer. The study employs the leading quality of life tools to measure erectile function preservation, urinary and rectal toxicity, bladder control problems and other scores related to general post treatment unwanted effects.
