A Phase II Study Of Cetuximab (C225) In Combination With Chemoradiation In Patients With Stage IIIA/B Non-Small Cell Lung Cancer (NSCLC)

Inclusion Criteria

DISEASE CHARACTERISTICS:

- Histologically or cytologically confirmed non-small cell lung cancer (NSCLC) of 1 of
the following subtypes:

- Squamous cell carcinoma

- Adenocarcinoma (including bronchoalveolar cell)

- Large cell anaplastic carcinoma (including giant and clear cell carcinomas)

- Poorly differentiated/not otherwise specified NSCLC

- Stage IIIA (T1-2, N2, M0 or T3, N1-2, M0) or IIIB (T4, any N, M0 or any T, N2-3, M0)

- If the largest mediastinal node is < 2.0 cm in diameter and this is the basis
for stage III disease, then at least 1 of the nodes must be cytologically or
histologically positive

- Unresectable disease

- No totally resected tumors

- Tumors adjacent to a vertebral body allowed provided all gross disease can be
encompassed in the radiation boost field and the boost volume is limited to < 50% of
the ipsilateral lung volume

- Measurable disease

- Transudate, cytologically negative, non-bloody pleural effusions allowed provided the
tumor can be encompassed within a reasonable field of radiotherapy

- Pleural effusions seen on a chest CT scan are allowed provided they are not
visible on a chest x-ray and are too small to tap

- No asymptomatic or symptomatic brain metastases
