Table 4 Survival time estimates in months for progression-free survival, overall survival and loco-regional control.

From: Pre-radiotherapy plasma carotenoids and markers of oxidative stress are associated with survival in head and neck squamous cell carcinoma patients: a prospective study

Survivala All patients
n = 78
Only radiotherapy
n = 48
Post-operative radiotherapy
n = 30
Progression-free 28.1 (23.8-32.4) 23.8 (18.2-29.4) 31.5 (26.0-36.9)
Overall 34.7 (30.6-38.9) 29.1 (23.9-34.3) 42.8 (38.4-47.2)
Loco-regional control 32.8 (28.6-37.1) 29.2 (23.4-35.0) 34.5 (29.7-39.4)
  1. The survival time is calculated in all patients, only radiotherapy patients and post-operative radiotherapy patients.
