I have treated central lung tumors <4cm with 50Gy in 5 fractions for many years and rarely had any issues, and with excellent local control.  There is also substantial data from Japanese investigators that dose-fractionation schemes of 50Gy in 5 or 48Gy in 4 were well tolerated when treating...

Referring to the table below: • 54 Gy 3 fx BED10 = 151 Gy BED3 = 378 Gy• 60 Gy 5 fx BED10 = 132 Gy BED3 = 300 Gy• 55 Gy 5 fx BED10 = 115 Gy BED3 = 256 Gy• 48 Gy 4 fx BED10 = 105 Gy BED3 = 240 Gy• 50 Gy 5 fx BED10 = 100 Gy BED3 = 216 Gy Given the theoretical limitations of ...
