Hi. The survival rate
depends on what specific treatment was used in the clinical trial, and what organ the squamous cell carcinoma originated from (e.g. lung, head and neck, skin, unknown primary site, etc.). I can answer your question better if you can give me more details regarding the patient being treated (age, sex, etc.), the type of cancer being treated (lung, head and neck, etc.), and the treatment being given. Hope to hear from you soon.
