These patients, who were treated with radiotherapy, have a local recurrence
rate of around 5% in 5 years (meaning there's a 5% chance that the <span style = 'background-color: #dae8f4'>cancer</span> is
going to come back after 5 years). The overall survival is
82% in 5 years. But the 5-year cause-specific survival rate is
means that although 18% of this
patient population died within 5 years, only 2% died because of the cancer
. These statis
tics are very encouraging, indeed.
