This study deals with observation on clinical therapeutic effect and toxic and side effects of capecitabine plus Fuzheng Jiedu decoction supplemented and reduced prescription for advanced gastric cancer. From January 2011 to January 2014, 145 patients with gastric cancer diagnosed by surgery, gastroscopy and pathology in our hospital, with measurable tumor lesions, were enrolled in this study. They were aged 45-85 y, with mean age (62.3 ± 6.7) y, 75 males and 70 females. In the study group, the disease progression time and survival time were 2-19.5 mo and 4.5-24 mo, respectively with 5 cases survived, while those of the control group were 1.5-20 months and 4.2-23 mo, respectively, with 3 cases survived. The t test showed no significant difference between the two groups (p>0.05). The survival rate of 60 cases within 1 y in the study group (87.0 %) was significantly higher than that of the control group (59 cases, 77.9 %), and the difference was significant (p<0.05). The incidence rates of hand-foot syndrome, nausea and vomiting, diarrhea, abdominal pain, liver injury and neurotoxicity in the study group were 21.7 %, 2.9 %, 11.6 %, 7.2 %, 1.4 % and 17.4 %, which were significantly lower than that of the control group (43.4 %, 22.3 %, 25 %, 21.1 %, 11.8 % and 36.8 %) and the chi-square test showed a significant difference (p<0.05). Capecitabine plus Fuzheng Jiedu decoction supplemented and reduced prescription for treating advanced gastric cancer has a good therapeutic effect, less toxic and side effects and the patient’s quality of life is significantly improved. It is worthy of being popularized.
Capecitabine, Fuzheng Jiedu decoction, advanced gastric cancer
With the development of society and the change of human life style, digestive tract tumors, especially gastric cancer, become one of the major diseases that threaten human life and health . As a fluorouracil-based oral cytotoxic agent, capecitabine is non-cytotoxic, easy to administer and has good efficacy against digestive tract tumors .
However, in clinical application, oral capecitabine is easy to produce adverse reactions such as hand-foot syndrome, stomatitis and nausea and vomiting, which seriously affect patients quality of life . Professor Yu Rencun  pointed out that the combination of chemotherapy and traditional Chinese medicine in the treatment of digestive tract tumors can reduce toxic and side effects and improve patients symptoms.
In this study, capecitabine plus Fuzheng Jiedu decoction supplemented and reduced prescription was used to treat patients with advanced gastric cancer with poor tolerance. The quality of life was improved after treatment with capecitabine plus Fuzheng Jiedu decoction supplemented and reduced prescription and the effect was good. It is reported below.
Materials and Methods
From January 2011 to January 2014, 145 patients with gastric cancer diagnosed by surgery, gastroscopy and pathology in our hospital, with measurable tumor lesions, were enrolled in this study. They were aged 45-85 y, with mean age (62.3±6.7) y, 75 males and 70 females. All patients were in stage VI according to international tumor (T), nodes (N) and metastases (M) TNM classification of malignant tumors.
Performance status score (Karnofsky performance status scale (KPS) score)) was below 60 points in 9 cases, 61-70 points in 78 cases, 71-80 points in 47 cases and 81-90 points in 11 cases and the predicted survival time was higher than 3 mo. All patients showed no contraindication to chemotherapy on blood routine examination, electrocardiography (ECG) and liver and kidney function examination and were given the same life care and health education during the treatment period.
According to the order of admission, the patients were divided into control group (n=76) and study group (n=69). The former was treated with capecitabine alone and the latter with capecitabine and traditional Chinese medicine. There was no statistical difference in the basic data of gender, age and disease course between the two groups, which was comparable (p>0.05). In addition, consent was obtained from the patient and his/ her family and informed consent was obtained.
Study methods: All patients received oral capecitabine (trade name: Xeloda, purchased from Shanghai Roche Pharmaceutical Co., Ltd.) 1000 mg/m2, twice daily after 30 min meal for 14 d, followed by 7 d off treatment, i.e. 21 d was considered as one treatment cycle. Each patient was orally administered for at least 2 cycles. The blood routine and liver and kidney function were examined before and after the completion of chemotherapy and the therapeutic effect and toxic and side effects were observed and evaluated.
Treatment plan of traditional Chinese medicine: Chinese medicine Fuzheng Jiedu decoction was used in this group. Its basic formula was Codonopsis pilosula 15-20 g, Astragalus membranaceus 15-20 g, Rehmannia glutinosa 10-15 g, Radix paeoniae Alba 10-15 g, Curcuma zedoary 15 g, Rhizoma polygonati 12-15 g, edible tulip 15 g, Salvia chinensis 15 g, raw oyster 30 g, Scutellaria barbata 30 g and endothelium corneum gigeriae galli 10 g. Since oral administration of capecitabine, Fuzheng Jiedu decoction was orally administered, twice/d, until the end of chemotherapy course.
Combine the side effects of capecitabine and the patient’s constitution, add and subtract the components as appropriate: add 10 g of XuanHuSuo, 10 g of Curcuma sichuanensis and 10 g of Aspongopus for abdominal pain patients; subtract Rehmannia glutinosa and add 10 g of stir-baked Dioscoreae rhizoma, 10 g of Aspongopus and 10 g of Poria cocos for diarrhea patients; add 10 g of ginger processed Pinellia,10 g of Pericarpium citri reticulatae, 6 g of Alpinia katsumadai Hayata, 6 g of Amomi Fructus for nausea patients; add 15 g of Alismatis rhizoma, 6 g of Cassia twig, 15 g of pericarpium Arecae for abdominal effusion patients; add 15 g of Radix Ophiopogonis, 15 g of Scrophulariae radix, 15 g of glossy privet fruit for patients with yin deficiency, epigastric noise and red tongue with little moss; add 12 g of Fructus Psoraleae, 12 g of Herba Epimedii and 12 g of Fructus Evodiae for patients with yang deficiency and fear of cold, vomit and deep pulse; add 20 g of cortex dictamni, 20 g of radix Sophora flavescens, 20 g of Zaocys dhumnades and 20 g of Caulis spatholobi for patients with severe hand-foot syndrome.
Investigation indicators: The short-term efficacy (change of tumor body), patient’s quality of life, long- term efficacy and toxic and side effects were used as indicators to evaluate the therapeutic efficacy. The short-term efficacy was evaluated by the change of tumor body. After the completion of chemotherapy, reexamination of magnetic resonance imaging (MRI) or computed tomography (CT) was performed to observe the size of solid tumor according to response evaluation criteria in solid tumors (RECIST) . It can be divided into progression (PD), stability (SD), partial response (PR) and complete response (CR). The effective rate of PR+CR and disease control rate of PR+CR+SD were calculated.
According to Karnofsky (KPS) scoring system , the quality of life score can be divided into improvement (difference higher than 10 points), stability (difference between 10 and -10 points) and reduction (difference lower than -10 points) according to the difference of scores before and after treatment. Long-term efficacy; the time of disease progression and survival time of all patients were calculated from the start of chemotherapy to the end of death. The survival rates within 1 y were observed and compared between the two groups. Toxic and side effects: With reference to the acute and sub- acute toxic reaction grading standard established by World Health Organization (WHO) , they were classified as grades 0-IV.
Statistical package for the social sciences (SPSS) 17.0 was used for data analysis, χ2 test was used for comparison of counting data and t test was used for comparison of measuring data. p<0.05 was used for statistically significant results.
Results and Discussion
Comparison of recent efficacy was done below. The effective rate and disease control rate were 30.4 % and 68.1 % in study group and 25 % and 51.3 % in control group, respectively. Chi-square test showed no significant difference between the two groups (p>0.05) (Table 1).

Table 3: Comparison of Incidence of Toxic and Side Effects
Gastric cancer is the most common type of malignant tumor, with the fourth highest incidence and the second highest mortality rate. In China, 360 000 people die of gastric cancer every year . Therefore, exploring an effective treatment for advanced gastric cancer is of great importance in improving quality of life and quality of survival . Capecitabine is a fluoropyrimidine anti-cancer drug.
The oral therapeutic effect of capecitabine alone is significantly higher than that of 5-fluorouracil intravenous injection. The concentration of capecitabine in tumor tissue is significantly higher than that in normal tissue and capecitabine has good anti-tumor effect on drug-resistant cell lines.
Okines et al. reported that the efficacy rate of oral capecitabine in the treatment of advanced gastric cancer was up to 24 %. Therefore, oral capecitabine is an option when patients are unwilling to receive combination chemotherapy or are poorly tolerated . In clinical studies, the most significant adverse reaction of oral capecitabine was hand-foot syndrome . Tang et al. noted that the incidence rate of capecitabine hand- foot syndrome was 44.4 %; Mainour et al.  found that the adverse reactions of capecitabine were significantly related to the oral dose: the incidence rate of hand- foot syndrome was 100 % at the dose of 2500 mg and reduced to 77.08 % at the dose of 2000 mg. Therefore, to avoid significant adverse reactions, the selection of reasonable dose of capecitabine was particularly critical.
In addition to selecting appropriate doses, traditional Chinese medicine is also a comprehensive treatment for tumors, which has significant advantages in overcoming the adverse effects of chemotherapeutic drugs .
Traditional Chinese medicine’s understanding of the pathogenesis of cancer is divided into two aspects: vital qi weakness and domination of pathogen .
Most of the patients in this group had advanced gastric cancer and stomach as the basis of after birth. Therefore, weakness of spleen and stomach, stagnation of toxic stasis and deficiency of qi and blood were considered as the pathogenesis. Therefore, Astragalus membranaceus, Atractylodis macrocephalae rhizoma and Codonopsis pilosula were chosen to supplement qi , Radix paeoniae Alba, Rhizoma polygonati and Rehmannia glutinosa to nourish blood , Salvia chinensis, Curcuma zedoary and raw oyster to invigorate the circulation of blood, Scutellaria barbata and edible tulip to disinfect . The addition and decrease of the components with the disease are beneficial to relieving qi and stopping vomiting, with the effect of nourishing Yin and reinforcing Yang, so it can achieve the effect of strengthening the body and detoxifying and reduce the toxic and side effects.
In this study, the efficacy of capecitabine combined with traditional Chinese medicine in the treatment of patients with gastric cancer was comparable to that of capecitabine alone. There was no significant difference in the patient’s survival time. However, the patient’s quality of life was significantly improved and the incidence rate of toxic and side effects was lower than that of capecitabine combined with traditional Chinese medicine Fuzheng Jiedu decoction alone. It indicated that the combination of capecitabine and traditional Chinese medicine Fuzheng Jiedu decoction in the treatment of patients with advanced gastric cancer who were difficult to tolerate and had poor physical condition could indeed reduce the adverse drug reactions and high quality of life improvement and disease control rates were achieved.
In this study, according to the patient’s toxic and adverse symptoms supplemented and reduced prescription, for syndrome differentiation combined with syndrome differentiation and differentiation, it is an effective exploration for the target treatment of tumor by the combination of traditional Chinese and western medicine. This is consistent with the principle and effect of Cunren et al. combined with Yiqi Huoxue traditional Chinese medicine and chemotherapy preparation in treatment of advanced digestive tract tumors .
In this study, by observing the changes of various indicators, Fuzheng Jiedu decoction supplemented and reduced prescription could effectively improve the clinical yield of patients and significantly improve the toxic and side effects of capecitabine, including hand- foot syndrome, vomiting and other adverse reactions, indicating that the combined treatment with traditional Chinese medicine has definite anti-toxic and synergistic effects. Therefore, capecitabine plus Fuzheng Jiedu decoction supplemented and reduced prescription for treatment of advanced digestive tract tumors has good therapeutic effect, less toxic and side effects and the patient’s quality of life has been significantly improved, thus deserving to be widely used. However, it is necessary to expand the sample to further observe and confirm the advantages of integrated traditional Chinese and western medicine in the treatment of gastric cancer.
