Between 1985 and 1990 the Swiss Group for Clinical Cancer Research (SAKK) for the first time assessed quality of life (QL) variables in 188 patients in a multicenter small-cell lung cancer trial that compared two different regimens of combination chemotherapy. QL-assessment was scheduled at the beginning of each of the six treatment cycles. The self-rating QL questionnaire included an early version of the EORTC QL questionnaire, a mood adjective checklist (Bf-S) and a single linear analogue scale (LASA) measuring general well-being. Compliance with completion of the scheduled questionnaires varied between 37% and 58% over the six cycles, and between 21% and 68% among the 7 participating institutions. Mean compliance was 49%. The institution was found the only significant factor predicting compliance (p < 0.001). Patient age, sex, education and biological prognostic factors at randomization were not predictors of compliance. Although compliance was poor, the data received was of high quality. We suggest practical guidelines for improving compliance with QL data collection in multicenter clinical trials.
