Post-operative Management and Outcomes
Following surgery, 2 patients received proton beam radiation therapy,
including one with widely disseminated disease and another with
increased mitotic activity and necrosis; neither has recurred at last
follow-up (1.18 and 3.19 years). No patient received chemotherapy.
Two patients with disseminated disease, elevated mitotic activity, and
necrosis had new metastatic disease/progression of non-resected
metastatic foci at 2.6 and 26.8 months. One patient underwent an
incomplete surgical resection of the original tumor. Both of these
patients received radiation therapy, and have remained progression free
since (3.01 and 9.34 years). All patients were alive at last follow-up
(median follow-up 1.31 years, range: 0.66-11.75 years).
