Primary Outcome Measures:
  • Rate of Local Control [ Time Frame: up to 3 years ] [ Designated as safety issue: No ]

    The proportion of patients with local control where local control is defined as no recurrence or disease progression in the primary disease site.

    Disease progression was defined using either the RECIST or Pet criteria. Using the RECIST criteria disease progression is defined as a more than 25% tumor increase by volume and/ or presence of a new lesion. Using the Pet criteria disease progression is defined as an increase in PET activity as compared to the scan used in the planning of the treatment; any subsequent increase in SUVmax was defined as local progression.

Secondary Outcome Measures:
  • Median Overall Survival Time [ Time Frame: up to 3 years ] [ Designated as safety issue: No ]
    The survival time for each patient is measured as the number of months from randomization until the time of death from any cause. The median survival time is computed using Kaplan Meier curves.
