Study Details

Brief summary:

Previous studies of this type of head and necl cancer have shown high rates of cancer control but result in many short and long term side effects when treated with high dose radiation and chemotherapy. Recently, investigators have noticed similar high rates of cancer control in small numbers of patients who receive less intensive treatments using lower doses of radiation, smaller radiation fields with chemotherapy. It is expected that the side effects of treatment with lower doses of radiation would be less.

For this reason this study is looking at a different regimen of reducing the intensity of the treatment.

The purpose of this study is to compare any good and bad effects of using lower dose smaller fields radiation therapy and chemotherapy with published outcomes. This study will allow the researchers to know whether these different approaches are better, the same, or worse than the usual approach. To be better, the study approach should result in the same survival rate of the usual approach (about 85 out of 100 patients alive and free of cancer at 2 years) but with less long-term side effects.

Interventions and Outcome Measures

Arms

experimental: Experimental

Cisplatin: 30-40 mg/m2/week, every week during radiation. Dose should be based on actual body weight. The first cisplatin infusion should be started within 24 hours before or after the first scheduled radiation treatment.

Intensity Modulated Radiation Therapy (IMRT) and Image-Guided Radiation Therapy (IGRT) are mandatory for this study.

55 Gy radiation in 5 weeks using 5 fractions per week + Cisplatin every week

Interventions

Modified dose and fields intensity modulated radiotherapy

Instead of standard bilateral or extensive neck fields, the current radiation fields will cover disease with only 3cm expansion. The clinical target volumes doses are biologically equivalent to the standard but given in a shorter hypofractionated approach.

Primary outcome measure

  • Two-year progression free survival [ Time Frame: 2 years ]
