STUDY DESIGN: Retrospective case series. PURPOSE: To investigate the oncological outcomes, including distant relapse, after en bloc spondylectomy (EBS) for spinal metastases in patients with a minimum of 2-year follow-up. OVERVIEW OF LITERATURE: Although EBS has been reported to be locally curative and extend survival in select patients with spinal metastases, detailed reports regarding the control of distant relapse after EBS are lacking. METHODS: We conducted a retrospective review of 18 consecutive patients (median age at EBS, 62 years; range, 40–77 years) who underwent EBS for spinal metastases between 1991 and 2015. The primary cancer sites included the kidney (n=7), thyroid (n=4), liver (n=3), and other locations (n=4). Survival rates were estimated using the Kaplan–Meier method, and groups were compared using the log-rank method. RESULTS: The median operative time and intraoperative blood loss were 767.5 minutes and 2,375 g, respectively. Twelve patients (66.7%) experienced perioperative complications. Five patients (27.8%) experienced local recurrence of the tumor at a median of 12.5 months after EBS, four of which had a positive resection margin status. Thirteen patients (72.2%) experienced distant relapse at a median of 21 months after EBS. The estimated median survival period after distant relapse was 20 months (95% confidence interval, 0.71–39.29 months). No association was found between resection margin status and distant relapse. Overall, the 2-year, 5-year, and 10-year survival rates after EBS were 72.2%, 48.8%, and 27.1%, respectively. Importantly, the era in which EBS was performed did not impact the oncological outcomes. CONCLUSIONS: Our results suggest that EBS by itself, even if margin-free, cannot prevent further dissemination, which occurred in >70% of patients at a median of 21 months after EBS. These results should be considered and conveyed to patients for clinical decision-making.

Effects of 20km running uppn taking a low-carbohydrate, high-fat and protein diet on the changes in blood pressure, heart rate, body weight, skinf old thickness, blood components and urinary recordings in five healthy young men were investigated and the changes in these items which occured by taurine inducement were studied by double blind test method. The results were as follows:
1) As to the degree of decrease in body weight in 20km running, the case in taurine administration (T. A.) was more than in placebo administration (P. A.) .
2) As to the degree of increase in systolic pressure upon 20km running, T. A. was less than P. A. 3) The rate of creatine kinase isozyme (CK-MB) against creatine kinase (CK), which increased after 20km running in P. A., was possible to reduce by T. A.
4) T. A. was less than P.A. in the rate of increase in lactate dehydrogenase (LDH) on 20km running.
5) In P. A., triglyceride increased after 20km running, but in T. A., it decreased.
6) T. A, much influenced the rate of individual fatty acid composition on 20km running
7) T. A, was more than P. A. in the secretion of adrenaline on 20km running.
8) No changes were observed in other blood components and urinary kallikrein.
