ABSTRACT

OBJECTIVE: To observe the effects of Jianpi Yishen Recipe (JPYSR), a compound Chinese herbal medicine, on recurrence, metastasis and life span of mice transplanted with proventriculus squamous carcinoma cells after tumorectomy. METHODS: JPYSR was orally administered to 615 mice transplanted with proventriculus squamous carcinoma cells in the palma of left hind limb after tumorectomy. The local tumor recurrence, lung metastasis and life span of the mice were evaluated and compared with those of the 5-FU-treated mice and untreated mice. RESULTS: The pulmonary metastasis rate was 94.4% and the recurrence rate was 94.44% in untreated group. The pulmonary metastasis rate was 68.4%, the inhibition rate of pulmonary metastasis was 27.5%, the recurrence rate was 78.95%, and the inhibition rate of tumor recurrence was 65.35% in JPYSR-treated group. The average and median life spans were obviously prolonged in JPYSR-treated group, as compared with those in untreated group. The life-prolonging rate was 100%. CONCLUSION: JPYSR can effectively inhibit the local recurrence and pulmonary metastasis of the transplanted proventriculus squamous carcinoma in mice after tumorectomy, and prolong the life span.
