What was measured

The FCSI consists of 9 questions comprising the most important symptoms associated with colorectal cancer, including energy, pain, weight, diarrhea, nausea, swelling or cramps in the stomach area, appetite, ability to enjoy life, and overall quality of life. The 9 questions are combined in three algorithms to provide information for 3 domains: colorectal cancer symptoms, physical well-being, and functional well-being. Each of the 9 items are scored from "0" to "4" representing "Not at All" through to "Very Much True". The raw score for all items is transformed to a 0-100 scale, and the average for each of the 3 subscales is calculated; high scores illustrate an improved state (e.g. able to enjoy life more).

Analysis population: Patient reported outcomes (PRO) analysis set participants with available data.

Groups in this outcome

Cetuximab

Cetuximab 400 mg/m\^2 as an initial dose, followed by 250 mg/m\^2 intravenously (IV) every 7 days.

Panitumumab

Panitumumab 6 mg/kg IV every 14 days.
