This is a cancer-specific questionnaire that consists of 30 items structured into 5 functional scales (physical functioning, role functioning, emotional functioning, cognitive functioning and social functioning), 3 symptom scales (fatigue, nausea and vomiting, pain), a global health status scale and, finally, 6 independent items (dyspnoea, insomnia, appetite loss, constipation, diarrhea and financial difficulties). Values from 1 to 4 are assigned depending on the patient's responses to the item. Only items 29 and 30 are evaluated with scoring from 1 to 7. Scores are standardised to obtain a score from 0 to 100, which determines the level of impact of the cancer on the patient for each scale. High scores on the overall health and functional status scales indicate a better QoL, while high scores on the symptoms scale would indicate a decrease in QoL since they indicate the presence of cancer-related symptoms.
