PURPOSE: Capecitabine is an oral fluoropyrimidine carbamate and it is known as an effective radiosensitizer. Capecitabine and its metabolite reach their peak concentration in the plasma at 1~2 hours after a single oral administration of capecitabine and the levels fall rapidly thereafter. To verify the radiosensitizing effect of capecitabine that is based on such pharmacokinetic characteristics, we performed a retrospective analysis on the optimal timing of capecitabine administration with performing preoperative chemoradiation for locally advanced rectal cancer. MATERIALS AND METHODS: Among 171 patients who were treated with preoperative radiotherapy and concurrent capecitabine administration for rectal cancer, 56 patients were administered capecitabine at 1~2 hours before radiotherapy (group A), and at other time in the other 115 patients (group B). Total mesorectal excision was done at 4 to 6 weeks after the completion of chemoradiation. The radiosensitizing effect of capecitabine was evaluated on the basis of the pathological response. RESULTS: Complete pathological regression of the primary tumor was observed in 12 patients (21.4%) for group A and in 11 patients (9.6%) for group B (p=0.031). Residual disease less than 0.5 cm (a good response) was observed in 19 patients (33.9%) for group A and in 23 patients (20.0%) for group B (p=0.038). On multivariate analysis, the capecitabine ingestion time showed marginal significance. CONCLUSION: When performing preoperative chemoradiation for locally advanced rectal cancer, the radiosensitizing effect of capecitabine was enhanced when it was administered 1 hour before radiotherapy.

OBJECTIVETo evaluate the clinical efficacy of capecitabine combined with transcatheter arterial chemoembolization (TACE) for advanced liver cancer.

METHODSForty-nine patients with liver cancer were retrospectively divided into two groups: Treatment group, on the basis of TACE, 23 patients received oral capecitabine at 2500 mg/m(2), twice-daily for 14 days followed by 7-day rest period and repeated in every three week intervals for more than two cycles. Control group, 26 patients received TACE only at 2-month intervals for at least two cycles.

RESULTSIn capecitabine and TACE group: there were 1 CR, 14 PR, 5 SD and 3 PD; the overall response rate was 65.2%; the AFP and tumor reduction rates were 68.8% and 73.9%; the median survival time was 11.9 months. In the TACE only group: there were 0 CR, 7 PR, 12 SD and 7 PD; the overall response rate was 26.9%; the AFP and tumor reduction rates were 31.6 % and 30.8%; the median survival time was 8.3 months. The most common side-effects of capecitabine were hand-foot syndrome and diarrhea.

CONCLUSIONCapecitabine combined with TACE is safe and effective for advanced liver cancer.

Objective: To explore the safety and efficacy of oxaliplatin plus capecitabine (CapeOX) or oxaliplatin plus S-1 (SOX) regimen neoadjuvant chemotherapy in the treatment of advanced gastric cancer. Methods: A retrospective cohort study was performed. Clinical data of patients diagnosed as advanced gastric cancer undergoing CapeOX/SOX neoadjuvant chemotherapy and standard laparoscopic radical operation for gastric cancer in Ruijin Hospital of Shanghai Jiaotong University School of Medicine from April 2016 to April 2019 were retrospectively collected. Inclusion criteria were as follows: (1) age≥18 years; (2) gastric adenocarcinoma was confirmed by histopathology and the clinical stage was T3-4aN+M0; (3) tumor could be resectable; (4) preoperative neoadjuvant chemotherapy was CapeOX or SOX regimen without radiotherapy or other regimen chemotherapy; (5) no other concurrent malignant tumor; (6) the Eastern Cooperative Oncology Group (ECOG) score ≤ 1; (7) no bone marrow suppression; (8) normal liver and kidney function. Exclusion criteria were as follows: (1) patients with recurrent gastric cancer; (2) patients receiving emergency surgery due to tumor perforation, bleeding, obstruction, etc.; (3) allergy to oxaliplatin, S-1, capecitabine or any drug excipients; (4) diagnosed with coronary heart disease, cardiomyopathy, or the New York Heart Association class III or IV; (5) pregnant or lactating women. A total of 118 patients were enrolled as the neoadjuvant chemotherapy group, and 379 patients with locally advanced gastric cancer who received surgery combined with postoperative adjuvant chemotherapy over the same period simultaneously were included as the adjuvant chemotherapy group. After propensity score matching was performed including gender, age, ECOG score, tumor site, clinical stage, chemotherapy regimen and other factors by 1:1 ratio, there were 40 cases in each group. The differences between the two groups in general conditions, efficacy of neoadjuvant chemotherapy, intraoperative conditions, postoperative conditions, histopathological results, chemotherapy-related adverse events, and survival status were compared and analyzed. Results: Comparison of baseline demographics between the two groups showed no statistically significant difference (all P>0.05). In the neoadjuvant chemotherapy group, 5.0% (2/40) of patients achieved clinical complete response, 57.5% (23/40) achieved partial response, 32.5% (13/40) remained stable disease, and 5.0% (2/40) had disease progression before surgery. Objective response rate was 62.5% (25/40), and disease control rate was 95.0% (38/40). There were no statistically significant differences between neoadjuvant chemotherapy group and adjuvant chemotherapy group in terms of operation time, intraoperative blood loss, number of lymph node harvested, length of postoperative hospital stay, and postoperative mortality and morbidity (all P>0.05). Postoperative complications were well managed with conservative treatment. No Clavien-Dindo IV or V complications were observed in both groups. Pathological results showed that the proportion of patients with pathological stage T1 in the neoadjuvant chemotherapy group was significantly higher than that in the adjuvant chemotherapy group [27.5% (11/40) vs. 5.0% (2/40)], while the proportion of patients with pathological stage T3 was significantly lower than that in the adjuvant chemotherapy group [20.0% (8/40) vs. 45.0% (18/40)], with statistically significant difference (χ(2)=15.432, P=0.001). In the neoadjuvant chemotherapy group, there were 4 cases of tumor regression grade 0, 8 cases of grade 1, 16 cases of grade 2, and 12 cases of grade 3. The pathological complete response rate was 10% (4/40), the overall pathological response rate was 70.0% (28/40). There was no statistically significant difference in the incidence of chemotherapy-related adverse events between neoadjuvant chemotherapy group and adjuvant chemotherapy group [40% (16/40) vs. 37.5% (15/40), P>0.05). There were no statistically significant differences in OS (43 months vs. 40 months) and 3-year OS rate (66.1% vs. 59.8%) between neoadjuvant chemotherapy group and adjuvant chemotherapy group (P=0.428). The disease-free survival (DFS) and 3-year DFS rates of the neoadjuvant chemotherapy group were significantly superior to those of the adjuvant chemotherapy group (36 months vs. 28 months, 51.4% vs. 35.8%, P=0.048). Conclusion: CapeOX or SOX regimen neoadjuvant chemotherapy is a safe, effective and feasible treatment mode for advanced gastric cancer without increasing surgical risk and can improve the DFS of patients.

OBJECTIVETo compare oncologic outcomes between doublet and triplet adjuvant chemotherapy for gastric cancer patients undergoing radical resection.

METHODSPatients with gastric cancer receiving adjuvant chemotherapy after radical resection from January 2004 to December 2008 were included. Doublet was defined as 5-FU 750 mg/m² (days 1-5) or capecitabine 1000 mg/m² (days 1-14) plus cisplatin 60 mg/m² (day 1) or oxaliplatin 130 mg/m² (day 1), while triplets had epirubicin 50 mg/m² (day 1) added. Chemotherapy was initiated 4-6 weeks after surgery, repeated every three weeks for 6 cycles. Patients were followed-up in the outpatient clinic until death or the most recent follow up(April 30, 2010). Cox proportional- hazard model and Chi-square test were used to test statistical difference.

RESULTSA total of 316 patients (210 received doublets, 106 received triplets) had a median follow-up time of 47 months. Seventy-seven patients died at the end of the follow-up. Two groups were comparable except for age (median age of 57 in doublets, 51 in triplets, P<0.01). The two groups had similar disease-free survival (16 months vs. 23 months, P=0.656) and 3-year overall survival(59.6% vs. 64.8%, P=0.293). There was no significant difference in severe adverse side effects between the two groups (21.9% vs. 30.2%, P=0.107).

CONCLUSIONTriplet adjuvant chemotherapy appears not to be associated with superior efficacy than doublet regimen for patients with gastric cancer after radical resection.

OBJECTIVETo evaluate the efficacy and safety profile of XELOX (capecitabine/oxaliplatin) in patients with locally advanced gastric cancer who underwent curative D2 resection in China.

METHODSThis is a subgroup analysis of Chinese patients in the capecitabine and oxaliplatin adjuvant study in stomach cancer (CLASSIC study), which was a randomised, open-label, multicentre, parallel-group, phase III( study in the Asia-Pacific region. A total of 100 gastric cancer patients who received curative D2 gastrectomy were enrolled in this study and were randomly assigned to either XELOX group (oral capecitabine combined with intravenous oxaliplatin chemotherapy) or the control group (surgery alone). This study aims to compare the 3-year disease-free between the two groups.

RESULTSSubgroup analysis showed that 3-year DFS rate were 78% and 56% in XELOX and control group, respectively. The risk of relapse in XELOX group was reduced by 59% (HR=0.41, 95%CI:0.20-0.85, P=0.013), compared with the control group. The 3-year overall survival rate were 78% and 66% in XELOX and control group, with no statistically significant difference (HR=0.55, 95%CI:0.26-1.16, P=0.110).

CONCLUSIONAdjuvant XELOX chemotherapy following D2 gastrectomy may improve the survival in patients with advanced gastric cancer in China.

OBJECTIVETo evaluate the efficacy and adverse effects of weekly irinotecan combined with capecitabine as a second-line chemotherapy for treatment of advanced gastric cancer.

METHODSTwenty-one patients with advanced gastric cancer who had failed first-line therapy received irinotecan on days 1 and 8 plus capecitabine on days 1-14 for a 21-day cycle. Each patient was treated for at least two cycles and evaluated 4 weeks later for the responses.

RESULTSOf the 21 patients, none showed complete remission (CR), 5 (23.8%) showed partial remission (PR), 6 (28.6%) showed stable disease (SD) and 10 (47.6%) showed progressive disease (PD). The overall response rate was 23.8%, and 11 patients (52.4%) benefited (CR+PR+SD) from the clinical therapy, with a mean time to tumor progression of 3.61±0.97 months. The main adverse effects of this regimen included myelosuppression, nausea, vomiting and diarrhea.

CONCLUSIONThe regimen of weekly irinotecan plus capecitabine has a definite effect for treatment of advanced gastric cancer with tolerable toxicity.

OBJECTIVETo evaluate the efficacy and safety of bevacizumab plus capecitabine in treating metastatic colorectal cancer(mCRC).

METHODSEleven patients with mCRC (6 females and 5 males) were enrolled in this study. Bevacizumab was given with 5 mg/kg every two weeks in five patients, 10 mg/kg every two weeks in four patients and 15 mg/kg every three weeks in two patients. All patients received capecitabine 2000 mg/m2 per day for 14 days.

RESULTSFive of 11 patients had partial response and five patients had stable disease and two patients had progressive disease. The disease control rate was 90.9%. The progress-free survival were 4 months and the median overall survival time were 15 months. The adverse events related to bevacizumab were grade 2 hypertension in 3 patients (27.3%) and grade 1 or 2 proteinuria in 4 patients (36.4%). Other adverse events such as mucositis, fatigue, subcutaneous haemorrhage were also observed. No thromboembolism or severe haemorrhage happened. No other grade 3 or 4 adverse events were observed.The adverse events in the combined therapy were hand-foot-syndrome (54.6%), diarrhea (27.3%), and neutropenia (18.2%), mainly due to capecitabine.

CONCLUSIONSThe combination of bevacizumab plus capecitabine has definite benefit in patients with mCRC. However,these benefits can not be maintained after the withdrawal of bevacizumab. The adverse drug reactions are well tolerated.

Objective: To investigate the effectiveness, safety, and prognosis of neoadjuvant chemoradiotherapy (nCRT) for Siewert type II and III adenocarcinomas of the esophagogastric junction (AEG). Methods: This study is a prospective randomized controlled clinical study (NCT01962246). AEG patients who were treated at the Third Department of Surgery of the Fourth Hospital of Hebei Medical University from February 2012 to June 2016 were included. All of the enrolled patients were diagnosed with type II or III locally advanced AEG gastric cancer (T2-4N0-3M0 or T1N1-3M0) by gastroscopy and CT before operation; the longitudinal axis of the lesion was ≤ 8 cm; no anti-tumor treatment was previously given and no contraindications of chemotherapy and surgery were found. Case exclusion criteria: serious diseases accompanied by liver and kidney, cardiovascular system and other vital organs; allergy to capecitabine or oxaliplatin drugs or excipients; receiving any form of chemotherapy or other research drugs; pregnant or lactating women; patients with diseases resulting in difficulty to take capecitabine or with concurrent tumors. Based on sample size estimation, a total of 150 AEG patients were enrolled. Using the random number table method, the enrolled patients were divided into the nCRT group and the direct operation group with 75 cases in each group. The nCRT group received XELOX chemotherapy (capecitabine+ oxaliplatin) before surgery and concurrent radiotherapy (45 Gy, 25 times, 1.8 Gy/d, 5 times/week). Clinical efficacy of the nCRT group was evaluated by the solid tumor efficacy evaluation standard (RECIST1.1) and the tumor volume reduction rate was measured on CT. After completing the preoperative examination in the direct operation group, and 8-10 weeks after the end of nCRT in the nCRT group, surgery was performed. Laparoscopic exploration was initially performed. According to the Japanese "Regulations for the Treatment of Gastric Cancer", a transabdominal radical total gastrectomy combined with perigastric lymph node dissection was performed. The primary outcome was the 3-year overall survival (OS) and disease-free survival rate (DFS); the secondary outcomes were R0 resection rate, the toxicity of chemotherapy, and surgical complications. The follow-up ended on December 31, 2019. The postoperative recurrence, metastasis and survival time of the two groups were collected. Results: After excluding patients with incomplete clinical data, patients or family members requesting to withdraw informed consent, and those failing to follow the treatment plan, 63 cases in the nCRT group and 69 cases in the direct operation group were finally enrolled in the study. There were no statistically significant differences in baseline characteristics of the two groups (all P>0.05). Sixty-three patients in the nCRT group were evaluated by RECIST1.1 after treatment, the image based effective rate was 42.9% (27/63), and the stable disease rate was 98.4% (62/63); the tumor volume before and after nCRT measured on CT was (58.8±24.4) cm(3) and (46.6±25.7) cm(3), respectively, the effective rate of tumor volume reduction measured by CT was 47.6% (30/63). Incidences of neutrophilopenia [65.1% (41/63) vs. 40.6% (28/69), χ(2)=7.923, P=0.005], nausea [81.0% (51/63) vs. 56.5% (39/69), χ(2)=9.060, P=0.003] and fatigue [74.6% (47/63) vs. 42.0% (29/69), χ(2)=14.306, P=0.001] in the nCRT group were significantly higher than those in the direct surgery group. Radiation gastritis/esophagitis and radiation pneumonia were unique adverse reactions in the nCRT group, with incidences of 52.4% (33/63) and 15.9%(10/63), respectively. The classification of tumor regression of 63 patients in nCRT group presented as 11 cases of grade 0 (17.5%), 20 cases of grade 1 (31.7%), 28 cases of grade 2 (44.4%), and 5 cases of grade 3 (7.9%). Eleven (17.5%) patients achieved pathologic complete response. Sixty-one (96.8%) patients in the nCRT group underwent R0 resection, which was higher than 87.0% (60/69) in the direct surgery group (χ(2)=4.199, P=0.040). The mean number of harvested lymph nodes in the specimens in the nCRT group and the direct operation group was 27.6±12.4 and 26.8±14.6, respectively, and the difference was not statistically significant (t=-0.015, P=0.976). The pathological lymph node metastasis rate and lymph node ratio in the two groups were 44.4% (28/63) vs. 76.8% (53/69), and 4.0% (70/1 739) vs. 21.9% (404/1 847), respectively with statistically significant differences (χ(2)=14.552, P<0.001, and χ(2)=248.736, P<0.001, respectively). During a median follow-up of 52 (27-77) months, the 3-year DFS rate in the nCRT group and the direct surgery group was 52.4% and 39.1% (P=0.049), and the 3-year OS rate was 63.4% and 52.2% (P=0.019), respectively. According to whether the tumor volume reduction rate measured by CT was ≥ 12.5%, 63 patients in the nCRT group were divided into the effective group (n=30) and the ineffective group (n=33). The 3-year DFS rate of these two subgracps was 56.6% and 45.5%, respectively without significant difference (P=0.098). The 3-year OS rate was 73.3% and 51.5%,respectively with significant difference (P=0.038). The 3-year DFS rate of patients with the tumor regression grades 0, 1, 2 and 3 was 81.8%, 70.0%, 44.4%, and 20.0%, repectively (P=0.024); the 3-year OS rate was 81.8%, 75.0%, 48.1% and 40.0%, repectively (P=0.048). Conclusion: nCRT improves treatment efficacy of Siewert type II and III AEG patients, and the long-term prognosis is good.

OBJECTIVETo evaluate the efficacy and safety of cisplatin and capecitabine combination (XP) therapy for patients with metastatic triple negative breast cancer (TNBC) progressing after anthracycline and taxane treatment.

METHODSTwenty-nine metastatic TNBC patients were prospectively enrolled to receive capecitabine (1, 000 mg/m(2) twice daily on days 1-14) and cisplatin (75 mg/m(2) on day 1) , repeated every 3 weeks.

RESULTSWith a median of 6 cycles of XP, all 29 patients were evaluable for response, including 18 PR (62.1%), 6 SD (20.7%), 5 PD (17.2%) and no CR. The response rate was 62.1%. Patients with earlier stage at diagnosis (stage I to IIIA), longer post-operative disease free survival (>2 years) and less metastatic sites (≤ 3) obtained significantly higher response rate than patients with later stage at diagnosis (stage IIIB to IV), shorter post-operative disease free survival (≤ 2 years) and more metastatic sites (>3). The leading side effects were grade 1/2 gastrointestinal and hematological toxicities. Grade 3/4 toxicities included neutropenia (34.5%), leukocytopenia (31.0%), anemia (6.9%), thrombocytopenia (3.4%), nausea/vomiting (20.7%), stomatitis (3.4%), and hand-foot syndrome (3.4%).

CONCLUSIONCisplatin and capecitabine combination therapy is an active and well-tolerated doublet treatment in metastatic TNBC patients progressing after anthracycline and taxane treatments.
