The authors claimed that survival decreased by 0.6%/d and pelvic control decreased by 0.7%/d for each additional day of treatment beyond 55 days for all stages of disease. Similarly, a study conducted by Lanciano et al 9 demonstrated a quite significant decrease in survival ( p = 0.0001) and pelvic control ( p = 0.0001) as the OTT increased from less than 6, 6 to 7.9, 8 to 9.9, and greater than 10 weeks.
