Overview
Brief Summary
The primary purpose of this study is to assess the effectiveness of ZD1839 250 mg and 500 mg when given either concomitantly or as maintenance to a standard therapy of radiotherapy (X-rays) plus chemotherapy (cisplatin) in terms of local disease control (progression-free) rate at 2 years.

Outcomes
Primary Outcomes
Local Disease Control Rate at 2 Years
Time Frame: Assessed at 2 yrs. Tumour assessments (clinical & by CT/MRI) were carried out during screening & regularly throughout the study until disease progression (as defined by Response evaluation criteria in solid tumours (RECIST)).
A patient demonstrated local disease control at 2 years if there was no evidence of failure of treatment. Failure was defined as the patient having objective disease progression (as per RECIST) inside the original irradiated area, at an isodose level (between 20% and 95%), or death.
Secondary Outcomes
- Local Disease Control Rate at 1 Year(Assessed after 1 year. Tumour assessments (clinical and by CT/MRI) were carried out during screening & regularly throughout the study until disease progression (as defined by RECIST).)
- Complete Response(Assessed at 2 years. Clinical tumour assessments and tumour assessment by CT/MRI were carried out during screening and regularly throughout the study until disease progression.)
- Tumour Response (Complete Response + Partial Response)(Assessed at 2 years. Clinical tumour assessments and tumour assessment by CT/MRI were carried out during screening and regularly throughout the study until disease progression)
- Progression Free Survival(Clinical tumour assessments and tumour assessment by CT/MRI were carried out during screening and regularly throughout the study until disease progression (as defined by RECIST))
- Overall Survival(Overall survival assessed at 2 years)
- Safety and Tolerability(Assessed over two years)
