Whether a seven days course of anti-alpha beta cell receptor-antibody (alpha beta-TCRmAb) combined with FK506 therapy promotes survival of limb allografts in fully MHC-mismatched combination (Brown Norway --> Lewis) was examined. Eight animals received 250 microgram/kg/day of alpha beta-TCRmAb for 7 days and 2 mg/kg/day of FK506 postoperatively (Combination therapy group). Eight animals had FK506 only (Mono-therapy group) and five animals did not have treatment (Control group). Clinical signs of early rejection with edema or erythema in the skin occurred at an average of 8.6+/-1.5 days postoperatively in Control group and 59.0+/-8.3 days in Mono-therapy group, both of which proceeded to irreversible rejection with necrosis of the epidermis and finally mummification. In Combination therapy group, all animals showed evidence of early rejection at an average of 56.8+/-12.6 days postoperatively, however, in 4 of 8 limbs, early rejection resolved without any treatment and limbs survived >1 year. At 9 months postoperatively, donor skin grafts were accepted and third-party skin grafts were rejected by all four survivors, demonstrating donor-specific tolerance. Little or no detectable chimerism was observed in any of the 4 surviving animals at one-year postoperatively. Combination therapy of alphabeta-TCRmAb and FK506 resulted in long-term survival in fully MHC-mismatched limb transplants.

Purpose:
The enhanced recovery after surgery (ERAS) protocol for radical cystectomy aims to facilitate postoperative recovery and hasten a return to normal daily activities. This study aims to report on the perioperative outcomes of implementation of an ERAS protocol at a single Australian institution.
Materials and Methods:
We identified 73 patients with pT1–T4 bladder cancer who underwent open radical cystectomy at Western Health, Victoria between June 2016 and August 2021. A retrospective analysis of a prospectively maintained database was performed. Perioperative outcomes included length of hospital stay, nasogastric tube requirement and duration of postoperative ileus.
Results:
The median age was 74 years (interquartile range [IQR] 66–78) for the ERAS group and 70 years (IQR 65–78) for the preERAS group patients. All patients in each group underwent ileal conduit formation. The median length of hospital stay was 7.0 days (IQR 7.0–9.3) for the ERAS group and 12.0 days (IQR 8.0–16.0) for the pre-ERAS group (p=0.003). Within the ERAS group, 25.0% had a postoperative ileus, and 25.0% had a nasogastric tube inserted, compared with 64.9% (p=0.001) and 45.9% (p=0.063) respectively within pre-ERAS group. The median bowel function recovery time, defined as duration from surgery to first bowel action, was 5.0 days (IQR 4.0–7.0) in the ERAS group and 7.5 days (IQR 5.0–8.5) in the pre-ERAS group (p=0.016).
Conclusions
Implementation of an ERAS protocol is associated with a reduction in hospital length of stay, postoperative ileus and bowel function recovery time.

Purpose:
There has been limited work assessing the use of re-irradiation (re-RT) for local failure following stereotactic spinal radiosurgery (SSRS). We reviewed our institutional experience of conventionally-fractionated external beam radiation (cEBRT) for salvage therapy following SSRS local failure.
Materials and Methods:
We performed a retrospective review of 54 patients that underwent salvage conventional re-RT at previously SSRS-treated sites. Local control following re-RT was defined as the absence of progression at the treated site as determined by magnetic resonance imaging.
Results:
Competing risk analysis for local failure was performed using a Fine-Gray model. The median follow-up time was 25 months and median overall survival (OS) was 16 months (95% confidence interval [CI], 10.8–24.9 months) following cEBRT re-RT. Multivariable Cox proportional-hazards analysis revealed Karnofsky performance score prior to re-RT (hazard ratio [HR] = 0.95; 95% CI, 0.93–0.98; p = 0.003) and time to local failure (HR = 0.97; 95% CI, 0.94–1.00; p = 0.04) were associated with longer OS, while male sex (HR = 3.92; 95% CI, 1.64–9.33; p = 0.002) was associated with shorter OS. Local control at 12 months was 81% (95% CI, 69.3–94.0). Competing risk multivariable regression revealed radioresistant tumors (subhazard ratio [subHR] = 0.36; 95% CI, 0.15–0.90; p = 0.028) and epidural disease (subHR = 0.31; 95% CI, 0.12–0.78; p =0.013) were associated with increased risk of local failure. At 12 months, 91% of patients maintained ambulatory function.
Conclusion
Our data suggest that cEBRT following SSRS local failure can be used safely and effectively. Further investigation is needed into optimal patient selection for cEBRT in the retreatment setting.
