A proposed preoperative grading scheme to assess risk for surgical resection of primary and secondary intraaxial supratentorial brain tumors.

摘要: Although surgical resection of brain tumors has been performed for over a century, complications still occur with distressing frequency. The authors propose simple preoperative grading scheme to assess risk primary and secondary intraaxial supratentorial tumors. retrospectively reviewed the clinical records, neuroimaging studies, outcomes 224 surgeries in 207 patients from January 1993 December 1995 at Cleveland Clinic Foundation Brain Tumor Center. Subsequently, they considered statistically analyzed multiple variables related their lesions. Surgical was defined as any complication occurring within 30 days postoperatively, divided into transient operative complications, medical new sustained neurological deficits. Length stay also recorded. overall incidence 10.6% mortality rate 2.7%, median hospital 3 days. Patient age greater than 60 years (p < 0.001), Karnofsky Performance Scale scores 50 or less 0.03), previous irradiation tumor location eloquent regions depth invasion 0.001) independently predicted complicated outcome increased length stay. Finally, derived five-tier which these patient factors are added together obtain grade I V that corresponds This may be used identify higher facilitate comparison results between institutions individual surgeons.
