Inpatient mortality remained lower than expected, continuing the trend over the past 5 years. N = number of supratentorial craniotomies performed for brain tumor per year.

Karnofsky Performance Scale (N = 131)

2017

Functional status is measured by the Karnofsky Performance Scale (KPS), a widely used 11-point scale correlating to percentage values from 100% (no evidence of disease, no symptoms) to 0% (death). Performance status was stable or improved in approximately 88% of patients immediately after supratentorial craniotomy. Change in KPS status was defined as a change of ≥ 20 points.

Supratentorial Craniotomy for Glioma

The 30- and 180-day survival rates for supratentorial craniotomy for glioma were 99% and 94%, respectively (for the first 6 months of 2018) .

Supratentorial Craniotomy for Meningioma

Both the 30- and 180-day survival rates for supratentorial craniotomy for meningioma were 100% (for the first 6 months of 2018).

Supratentorial Craniotomy for Metastasis

The 30- and 180-day survival rates for supratentorial craniotomy for metastases were 100% and 97%, respectively (for the first 6 months of 2018)
