Interventions

Dose per fraction will be equally applied to gross primary tumor&#44
gross nodes and to elective nodes throughout an initial plan (2 Gy x 25 fractions&#44
total dose of 50 Gy). For high dose radiation&#44
the initial plan will be followed by a boost plan to gross primary tumor to a total dose of 60&#45
64 Gy in 30&#45
32 fractions (i.e. shrinking field technique),Dose per fraction will be equally applied to gross primary tumor&#44
total dose of 50 Gy). No boost will be added.
