However, there has yet to be a study focusing on the scientific competence of the planning, execution and result interpretation of these reports. Therefore, this paper analyzed the clinical trials in the Journal of Korean Cancer Association for the last 10 years.
MATERIALS AND METHODS

Clinical trials of surgical treatment were excluded from this study.
RESULTS

Among 157 studies (70.4%) that were prospective, 29 studies (18.5%) did not clearly define eligibility criteria. The most common defect in the results was the lack of patients for the analysis (68 trials, 43.3%), and the median size of the trial was 30 patients. Statistical errors were found in 38 trials (24.3%).
