From: Long-term results of radiotherapy in anaplastic thyroid cancer
Overall survival in subgroups of patients with anaplastic thyroid cancer: significantly improved survival was seen in (A) patients with any surgery vs. no surgery (p = 0.02) (B) patients with N0 status vs. N + status (p = 0.041) and (C) patients with a radiotherapy dose of at least 50 Gy vs. lower doses (p = 0.022).
