Table 9 Costs and overall survival based on good performance status (Karnofsky ≥70) and extent of resection/ablation—by procedure performed—percent likelihood of event occurring

From: The value of using a brain laser interstitial thermal therapy (LITT) system in patients presenting with high grade gliomas where maximal safe resection may not be feasible

Procedure Cost Overall Survival (months) % occurrence
Gross total resection/ablation (≥98 % EOR) and good performance status (Karnofsky ≥70)
 Brain LITT $91,356 22.58 36 %
 Craniotomy w/o carmustine wafer $89,698 21.75 9 %
 Craniotomy w/carmustine wafer $99,013 25.05 8 %
Subtotal resection (STR)/ablation (<98 %) and good performance status (Karnofsky ≥70)
 Brain LITT $89,721 17.46 61 %
 Craniotomy w/o carmustine wafer $86,493 16.95 49 % (of all OTHER treatments performed)
 Craniotomy w/carmustine wafer $99,679 20.25 15 % (of all OTHER treatments performed)
 Biopsy $62,959 12.72 21 % (of all OTHER treatments performed)
