摘要
The above therapeutic results show that TCM drugs have excellent effects in counteracting the metastasis of tumors. They can produce a synergistic effect when used together with surgery, radio- and chemotherapy. In analyzing the relationship between the factors that affect the distant metastasis, the authors strongly recommend that the FDM-survival rate be used, i.e. the survival rate free from distant metastasis as suggested by Hong Minghuang et al in their article. An analysis based on FDM-survival rate in a duration of three or five years with the data treated with the Kaplan-Meier and/or Life Table would be rational and convincible.
As one of the basic biologic features of malignant tumors and a major cause leading to failure of treatment and even death, metastasis has aroused a great interest among the medical researchers. To date, convincing evidence is still lacking as to whether metastasis could be controlled by surgery, radio- or chemotherapy. However, TCM measures have proved to be advantageous in improving the survival quality and prolonging the survival period by decreasing the rate of distant metastasis of tumors. The following is a brief summary on the advances in this field.
