RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Giving radiation therapy in different ways may kill more tumor cells. It is not yet known which regimen of radiation therapy is more effective in treating patients who have metastases to the lymph nodes in the neck.

PURPOSE: Randomizedphase III trial to compare different radiation therapy regimens in treating patients who have metastases to the lymph nodes in the neck from an unknown primary tumor.

Condition	Treatment or Intervention	Phase
newly diagnosed carcinoma of unknown primary squamous cell carcinoma of unknown primary	Procedure: radiation therapy	Phase III

Further Study Details: 

OBJECTIVES:

• Compare the disease-free survival of patients with cervical lymph node metastases of squamous cell carcinoma from an unknown primary treated with selective irradiation vs extensive irradiation.
• Compare the overall survival of patients treated with these regimens.
• Compare the incidence of acute and late side effects in the head and neck region in patients treated with these regimens.
• Compare control of the neck and incidence of subsequent primary in the head and neck region in patients treated with these regimens.
• Compare quality of life of patients treated with these regimens.

OUTLINE: This is a randomized, open-label, multicenter study. Patients are stratified according to disease stage (N1-2a vs N2b-3), radiation technique (2D vs 3D conformal vs intensity-modulated), and participating center. Patients are randomized to 1 of 2 treatment arms.

• Arm I: Patients undergo selective irradiation of the ipsilateral level of the neck once daily 5 days a week for 6 weeks.
• Arm II: Patients undergo extensive irradiation of the neck (nasopharyngeal, oropharyngeal, hypopharyngeal, and laryngeal mucosa and ipsilateral neck node areas on both sides of the neck) once daily 5 days a week for 6 weeks. In both arms, treatment continues in the absence of unacceptable toxicity or disease progression.

Quality of life is assessed at baseline, at week 4, on the last day of therapy, and then every 3 months for 1 year.

Patients are followed at day 30, every 3 months for 3 years, every 6 months for 2 years, and then annually thereafter.

PROJECTED ACCRUAL: A total of 600 patients (300 per treatment arm) will be accrued for this study within 7 years.

Ages Eligible for Study:  18 Years and above,  Genders Eligible for Study:  Both
