Design outcomes
Primary
| Measure | Time frame |
|---|---|
| primary outcome -To determine the efficacy of the treatment by correlating the variation of the maximum SUV in the primary tumor and in the cervical lymph nodes registered before the treatment and after the cycle 1 (fourteenth day) with the end points tumor recurrence or death (whichever occurs first) . The Kaplan-Meier method was used to estimate survival data and long-rank tests were used to compare disease-free and overall survival between the different groups observed (according to decrease or increase of SUV after treatment at the fourteenth day). Calculations of time-free of tumor recurrence or death were considered from the first day of the first cycle of induction chemotherapy and the occurrence of tumor recurrence or death, respectively. | — |
Secondary
| Measure | Time frame |
|---|---|
| secondary outcome- determine the overall survival of patients according to the maximum SUV variation in the primary tumor and cervical lymph nodes with the outcome of death (related cancer or non-cancer related) | — |
