immunoreactivity to cetuximab in cancer patients

Conditions: Colorectal Cancer; Head and Neck Cancer

Summary: rationale: studying samples of blood in the laboratory may help doctors predict which patients will develop hypersensitivity to cetuximab. purpose: this research study is looking at hypersensitivity to cetuximab in patients with head and neck cancer or advanced colorectal cancer previously treated with cetuximab.

objectives: * to examine serum samples from patients with head and neck cancer or advanced colorectal cancer previously treated with cetuximab for the presence of antibodies against cetuximab. outline: serum samples are examined by immunoreactivity screening of ige, igg, iga, and igm antibodies and complement reaction.

Eligibility criteria:
disease characteristics: * diagnosis of one of the following: * head and neck cancer * advanced colorectal cancer * previously treated with cetuximab * serum samples available from patients enrolled in one of the following clinical trials: * vu-vicc-gi-0410 (colorectal cancer) * vu-vicc-gi-0622 (colorectal cancer) * vu-vicc-hn-0356 (head and neck cancer) patient characteristics: * not specified prior concurrent therapy: * see disease characteristics
