70. Meningiomas treated in Greatpoland Cancer Center between 1990–1997

IntroductionWe analyzed correlation between age of patient with anaplastic meningiomas, extension of tumor excision, histopatological recognition and time to recurrence and survival.Material and methodsBetween 1990–1997 7 patients with anaplastic meningioma, 3 patients with haemangiopericytoma, 2 patients with sarcoma meningeum (6 women and 6 men) have been irradiated. 7 patients underwent radical excision of the tumor, 5 patients non radical. The patients were irradiated from limited fields to total dose 56–60 Gy/T mostly by energy Co-60 (9 patients) and photons 9 MV (3 patients).ResultsThere are 6 patients with anaplasticum meningioma still alive. 3 patients living 96–108 months, 3 other 30–39 months. Recurrence was confirmed in two male participants who underwent radical surgery in 12 and 29 month from the start of treatment. The first patient died after 16 months with recurrence of the disease. One patient (39 years old) with heamangiopericytoma lives 40 months after radical surgery without evidence of recurrence. Two patients died – one 11 months after radical surgery (41 years old) and the other one (42 years old) 21 months after non radical surgery. Both patients (24 and 59 years old) with sarcoma died (one after 8 months, and the other one after 21 months).ConclusionsPatient with anaplastic meningiomas have long survival. The extension of tumor excision didn’t influence on survival
