Adjuvant Radiotherapy in Early Stage Oral Cancers

"Conventional treatment planning, as well as intensity-modulated radiation therapy (IMRT) planning, would be allowed on the study with patients being stratified on the RT technique.~Treatment would be delivered on telecobalt unit (gamma-rays/linear accelerator (6MV photons). All fields would be treated daily.~Phase I: 46 Gray(Gy) in 23 fractions over 4.5 weeks Phase II: 14Gray in 7 fractions over 1.5 weeks~For IMRT, inverse planning would be done on a commercial TPS configured to deliver IMRT using 6MV photons. Patients shall be treated using the simultaneous integrated boost (SIB) technique with 5 fractions being delivered every week."
