Does the information level of cancer patients correlate with quality of life? A prospective study

The aim of the study was to evaluate the impact of information level on quality of life in cancer patients previously studied for their information level.

The information level was determined by means of a questionnaire that explored the degree of information on diagnosis and status of disease, the patient's interpretation of his/her disease status, and his/her satisfaction with the information received. Quality of life was evaluated, some months after evaluation of the information level, by means of the Functional Living Index for Cancer (FLIC) and the State-Trait Anxiety Inventory (STAI 1-2).

A total of 175 patients were studied. Information was adequate in 53.7% of patients. An adequate level of information was present more frequently among patients aged < or = 65 years and in those patients followed at a cancer institute. There was no difference in the quality of life of adequately versus inadequately informed patients. Satisfaction with the information received influenced quality of life in both age groups. Objective clinical variables (active disease present and ongoing treatment) negatively affected quality of life in patients <65 years, whereas the subjective perception of the presence of disease was associated with a worse quality of life in older patients.

In the study, although the level of information did not affect the quality of life, satisfaction with the information was associated with a better quality of life. The finding stresses the importance of a sensible disclosure of diagnosis and prognosis.
