RESUMEN
OBJECTIVE: To systematically review the effect of invigorating Pi and detoxification (Jianpi Jiedu, (JPJD)) herbs in advanced colorectal cancer (CRC) patients receiving chemotherapy. METHODS: Three English and four Chinese databases were searched. Literature was screened by EndNote X7 and data were analyzed by RevMan 5.2. RESULTS: This review comprised 12 randomized clinical studies of 701 patients. The results showed that JPJD herbs improved the therapeutic effect on Chinese medicine symptoms [risk ratio (RR) = 1.59; 95% confidence interval (CI): 1.35~1.88] and Karnofsky performance score [RR = 2.07; 95% CI: 1.52~2.82] for advanced CRC patients receiving chemotherapy, lowered the Chinese medicine symptoms' score [weighted mean difference = -2.44; 95% CI: -3.23~-1.64], reduced the incidence of nausea and vomiting [RR = 0.23; 95% CI: 0.11~0.49], improved platelet at toxicity grades III-IV [odds ratio = 0.29; 95% CI: 0.12~0.74] and I-IV [RR = 0.65; 95% CI: 0.51~0.82], and improved white blood cell at toxicity grades III-IV [RR = 0.37; 95% CI: 0.23~0.58] and I-IV [RR = 0.69; 95% CI: 0.60~0.79]. However, the results showed no significant effect on tumor response. CONCLUSION: JPJD herbs can improve quality of life, relieve symptoms, and reduce adverse events of advanced CRC patients receiving chemotherapy.
RESUMEN
OBJECTIVE: To investigate the effect of Chinese medicine (CM) on survival of patients with stage II and III colorectal cancer (CRC). METHODS: A total of 295 patients who received chemotherapy were assigned to Group 1. The other 171 patients received the same chemotherapy treatment combined with the usage of CM Jianpi Jiedu Formula (, JPJD) for more than 3 months (Group 2). Patients' survival time, relapse and metastasis, and cause of death were observed. Cox proportional hazard regression models were established for the analysis of the effect of independent factors on the survival prognosis of patients with CRC. RESULTS: The survival rate of patients in Group 2 was higher than that of Group 1 (P<0.05). Compared with Group 1, the mean survival time was prolonged by 5.594 months and the median survival time was prolonged by 6 months in Group 2 (P=0.004). Cox regression analysis indicated that CM combined with chemotherapy provided signifificant protective effect, as observed with the improvements in the survival rates of CRC patients (P<0.01). CONCLUSION: CM can improve the survival rate in patients with stage II and III CRC.
