临床决策问题的研究,已成为医学定量研究即数理研究的重要课题之一.通过代价-效益分析来评价和选择处理方案,是一条新的可行的途径.本文对临床检查未发现颈淋巴结转移的舌癌患者,是否行预防性颈清除术问题,提出了决策树模型,并以5年生存率为指标,就四种不同的临床处理方案作了代价-效益分析.所述方法不难推广应用到其他一些临床决策问题上去.
The study of clinical decision problems has become one of the important topics in medical quantitative research, ie, mathematical science research. It is a new and feasible way to evaluate and select treatment plans through cost-benefit analysis. This article did not find cervical lymph node metastasis on clinical examination. In patients with tongue cancer, whether a preventive neck dissection was performed or not, a decision tree model was proposed, and a five-year survival rate was used as an index to make cost-benefit analysis on four different clinical treatment options. The method is not difficult to promote and apply. Go to some other clinical decision problems.
