Prospective, Post Marketing Surveillance Study On Erbitux® (Cetuximab) in Patients With Locally Advanced or Recurrent and/or Metastatic Squamous Cell Cancer of the Head and Neck in Korea

This is a prospective, Post Marketing Surveillance (PMS) study on Erbitux® (Cetuximab) in patients with locally advanced or recurrent and/or metastatic squamous cell cancer of the head and neck in Korea
