We studied the influence of levels of follow-up (F/U) on survival curves in 100 patients with tongue cancer. The levels were defined according to the methods of F/U, such as chart review, direct contact with the patients or family, etc. Consequently, complete F/U data were obtained for all but one patient, who was missed after a 15-year period of no evidence of disease. The more complete the F/U data were, the lower the survival figures, however, the disease-specific survival figures were increased. The relapse-free rates were not changed with completing F/U. The P-values of the generalized Wilcoxon test and long-rank test rose with an increase of F/U levels.
我们研究了随访（F/U）水平对100例舌癌患者生存曲线的影响。随访水平根据随访方法定义，如病历审查、与患者或家属直接联系等。结果，除一名患者外，其他所有患者均获得了完整的随访数据，该患者在15年无疾病证据期后失访。然而，随访数据越完整，生存数据越低，但疾病特异性生存数据有所增加。无复发生存率并未随随访的完善而改变。广义Wilcoxon检验和长秩检验的P值随随访水平的增加而升高。
