Glioblastoma
The most common length of survival following diagnosis is 12 to 15 months, with fewer than 3% to 5% of people surviving longer than five years. Without treatment survival is typically 3 months.
Stan Zemanek
Zemanek was diagnosed with glioblastoma multiforme, an aggressive brain tumor that is almost universally fatal within a few years, in May 2006. Treatment included chemotherapy and radiotherapy in addition to surgery performed by Charles Teo. After rumours in 2006, Zemanek's retirement and intention to look after his health and spend time with his family was announced on 9 December 2006. His final show went to air on 22 December 2006. Many in the commercial radio industry paid tribute to Zemanek on-air, including his former on-air colleagues and later rivals (on 2GB), Alan Jones and Ray Hadley.
