Objective:Several studies have been conducted on the effects and toxicity of adding oxaliplatin to fluorouracilbased or capecitabine-based chemoradiotherapy(CRT)regimens as significantly increasing the toxic response without benefit to survival.In this study,we further explored the role of these two postoperative CRT regimens in patients with pathological stage N2 rectal cancer.Methods:This study was a subgroup analysis of a randomized clinical trial.A total of 180 patients with pathological stage N2 rectal cancer were eligible,85 received capecitabine with radiotherapy(RT),and 95 received capecitabine and oxaliplatin with RT.Patients in both groups received adjuvant chemotherapy[capecitabine and oxaliplatin(XELOX);or fluorouracil,leucovorin,and oxaliplatin(FOLFOX)]after CRT.Results:At a median follow-up of 59.2[interquartile range(IQR),34.0−96.8]months,the three-year diseasefree survival(DFS)was 53.3%and 64.9%in the control group and the experimental group,respectively[hazard ratio(HR),0.63;95%confidence interval(95%CI),0.41−0.98;P=0.04].There was no significant difference between the groups in overall survival(OS)(HR,0.62;95%CI,0.37−1.05;P=0.07),the incidence of locoregional recurrence(HR,0.62;95%CI,0.24−1.64;P=0.33),the incidence of distant metastasis(HR,0.67;95%CI,0.42−1.06;P=0.09)and grade 3−4 acute toxicities(P=0.78).For patients with survival longer than 3 years,the conditional overall survival(COS)was significantly better in the experimental group(HR,0.39;95%CI,0.16−0.96;P=0.03).Conclusions:Our results indicated that adding oxaliplatin to capecitabine-based postoperative CRT is safe and effective in patients with pathological stage N2 rectal cancer. 展开更多

BACKGROUND Numerous studies have indicated that the temozolomide and capecitabine regimen(TEMCAP)exhibits a certain level of efficacy in treating advanced,welldifferentiated gastroenteropancreatic neuroendocrine tumors(GEP-NET).However,published data from Peru are limited.We hypothesize that this regimen could be a viable therapeutic option for advanced GEP-NET in the Peruvian population.AIM To evaluate overall survival(OS)in patients diagnosed with advanced GEP-NET treated with TEMCAP at the Instituto Nacional de Enfermedades Neoplásicas(INEN)in Lima-Perú.METHODS A retrospective review was conducted to identify patients with GEP-NEN treated with the TEMCAP regimen between 2011 and 2021 at the INEN.A total of thirtyeight patients were included in the final analysis:Thirty-five received TEMCAP as a first-line treatment,and three as a second-line treatment.The primary objective was to evaluate OS.The efficacy and safety of TEMCAP were assessed until the occurrence of unacceptable toxicity or disease progression.Survival outcomes were estimated using the Kaplan-Meier method.RESULTS The median age of the patients was 52 years(range 24-77 years),and 53.3%were female.The most common symptoms at diagnosis were abdominal pain in 31 patients(81.6%).Primary tumors included 12 in the rectum(31.6%),11 in the pancreas(28.9%),3 in the ileum(7.9%),2 in the mesentery(5.3%),2 in the small intestine(5.3%),1 in the appendix(2.6%),1 in the stomach(2.6%)and 6 cases of liver metastasis of unknown primary(15.8%).Five were neuroendocrine tumors(NET)G1(13.2%),33 were NET G2(86.8%),five had Ki67<3%(13.2%),and 33 had Ki67 between 3%and 20%(86.8%).TEMCAP was administered to 35(92.1%)patients as first-line treatment.OS at 12,36,and 60 months was estimated in 80%,66%,and 42%,respectively,with a median OS of 49 months.CONCLUSION TEMCAP therapy is a viable first-line option regarding efficacy and tolerability in areas where standard therapy is inaccessible. 展开更多

BACKGROUND Capecitabine(CAP)is a classic antimetabolic drug and has shown potential antirejection effects after liver transplantation(LT)in clinical studies.Our previous study showed that metronomic CAP can cause the programmed death of T cells by inducing oxidative stress in healthy mice.Ferroptosis,a newly defined non-apoptotic cell death that occurs in response to iron overload and lethal levels of lipid peroxidation,is an important mechanism by which CAP induces cell death.Therefore,ferroptosis may also play an important role in CAP-induced T cell death and play an immunosuppressive role in acute rejection after transplantation.AIM To investigate the functions and underlying mechanisms of antirejection effects of metronomic CAP.METHODS A rat LT model of acute rejection was established,and the effect of metronomic CAP on splenic hematopoietic function and acute graft rejection was evaluated 7 d after LT.In vitro,primary CD3+T cells were sorted from rat spleens and human peripheral blood,and co-cultured with or without 5-fluorouracil(5-FU)(active agent of CAP).The levels of ferroptosis-related proteins,ferrous ion concentration,and oxidative stress-related indicators were observed.The changes in mitochondrial structure were observed using electron microscopy.RESULTS With no significant myelotoxicity,metronomic CAP alleviated graft injury(Banff score 9 vs 7.333,P<0.001),prolonged the survival time of the recipient rats(11.5 d vs 16 d,P<0.01),and reduced the infiltration rate of CD3+T cells in peripheral blood(6.859 vs 3.735,P<0.001),liver graft(7.459 vs 3.432,P<0.001),and spleen(26.92 vs 12.9,P<0.001),thereby inhibiting acute rejection after LT.In vitro,5-FU,an end product of CAP metabolism,induced the degradation of the ferritin heavy chain by upregulating nuclear receptor coactivator 4,which caused the accumulation of ferrous ions.It also inhibited nuclear erythroid 2 p45-related factor 2,heme oxygenase-1,and glutathione peroxidase 4,eventually leading to oxidative damage and ferroptosis of T cells.CONCLUSION Metronomic CAP can suppress acute allograft rejection in rats by triggering CD3+T cell ferroptosis,which makes it an effective immunosuppressive agent after LT. 展开更多

BACKGROUND In recent years survival of patients with metastatic colorectal cancer(mCRC),though still limited,has improved significantly;clearly,when the disease becomes refractory to standard regimens,additional treatment options are needed.Studies have shown that mitomycin C(MMC),an antitumor antibiotic,and capecitabine,a precursor of 5-fluorouracil,may act synergistically in combination.The efficacy of MMC/capecitabine has been demonstrated in the first-line setting,but only a few small studies have tested it in the advanced-line setting,with contradictory results.received a median of 2 MMC/capecitabine cycles(range 0.5-9.0).Thirty-four patients(28.6%)experienced grade≥3 toxicity,including 2(1.7%)with grade 4;there was no drug-related mortality.The objective response rate was 0.8%,and the disease control rate,24.4%.Median progression-free survival(PFS)was 2.1 mo(range 0.2-20.3),and median overall survival,4.8 mo(range 0.2-27.5).The 6-month overall survival rate was 44%;8.7%of patients remained progression-free.Factors associated with longer PFS were lower gamma-glutamyl transferase level(P=0.030)and primary tumor location in the left colon(P=0.017).Factors associated with longer overall survival were lower gamma-glutamyl transferase level(P=0.022),left-colon tumor location(P=0.044),low-to-moderate histological grade(P=0.012),Eastern Cooperative Oncology Group performance status 0-1(P=0.036),and normal bilirubin level(P=0.047).CONCLUSION MMC/capecitabine is an active,available,and relatively safe regimen for use beyond standard lines of therapy in mCRC.Several clinical and laboratory parameters can identify patients more likely to benefit. 展开更多

Objective: To examine therapeutic drug monitoring in managing hyperbilirubinemia caused by capecitabine in patients with gastric adenocarcinoma with extensive liver metastases. Results: The initial liver function tests showed an elevation of transaminases (aspartate amino transferase 615 UI/l, alanine aminotransferase 385.9 UI/l), hyperbilirubinemia (total bilirubin at 246.1 μmol/l), and alkaline phosphatase at 694.6 UI/l. We initiated capecitabine based combination chemotherapy, and the clinical pharmacist conducted a full-course medication monitoring of the patient’s treatment including design of individualized dosing regimens and monitoring of bilirubin, infection, cancer pain, parenteral nutrition support and adverse events. After 21 days of supervision by clinical pharmacist and clinicians, the patient’s bilirubin and transaminase decreased progressively, with aspartate aminotransferase, total bilirubin and alkaline phosphatase falling back to 57 UI/l, 69.8 μmol/l, 307.2 UI/l, respectively. The patient’s condition improved significantly at the time of discharge, with the jaundice subsided, and the bloating relieved. Conclusion: Due to adverse reactions, capecitabine requires medication monitoring during use. The relationship between effectiveness and adverse effects is controversial. Adverse reactions should not be the sole criterion for the use of drugs. Clinical pharmacists can improve the safety and effectiveness of patients’ medications and promote rational drug use by monitoring patients, which may be useful to help the doctors identify the high-risk patients for taking efficient treatment strategy decisions. 展开更多

Background:This study was conducted to evaluate the efficacy and safety of docetaxel/S-1(TS)compared with docetaxel/capecitabine(TX)as a first-line treatment for advanced breast cancer.Methods:Patients with advanced metastatic breast cancer were randomly divided into the TS group(n=54)and the TX group(n=57)for first-line chemotherapy from August 2015 to April 2019(ClinicalTrials.org registration no.NCT02947061).Following the completion of combination therapy,patients without progression received S-1 or capecitabine maintenance treatment.The primary end point was progression-free survival(PFS).Results:Among 111 enrolled patients,the median PFS did not differ significantly between the TS group and the TX group(TS vs.TX,9.0 vs.7.4 months,P=0.365,95%confidence interval[CI]:0.50-1.11,hazard ratio[HR]:0.75).There was also no statistically significant difference in median overall survival(OS)between the two groups(TS vs.TX,40.2 vs.41.3 months,P=0.976).In addition,visceral metastasis and metastasis sites,such as the liver or lung,did not lead to a significant effect on PFS and OS.The two regimens showed no significant difference in adverse events,except hand-foot syndrome,which predominated in the TX group(38.6%vs.7.4%,P=0.001),and diarrhea(24.1%vs.3.6%,P=0.003)and elevation of aspartate aminotransferase(AST)/alanine aminotransferase(ALT)levels(14.8%vs.3.5%,P=0.049),which were more frequent in the TS group.Conclusions:The TS and TX regimens demonstrated similar efficacy and safety for the first-line treatment of advanced breast cancer.The TS regimen had fewer cases of severe hand-foot syndrome than the TX regimen,representing an effective alternative option to the TX regimen.Further studies are warranted to define the efficacy and safety of this strategy in real-world settings. 展开更多

Aim To measure the penetration of capecitabine from the plasma into tissue and to investigate the pharmacokinetics of its metabolizing into fluorouracil (5-FU) in patients with advanced breast cancer. Methods Twenty-seven patients with breast cancer received repeated doses of 1 255 mg·m^-2 of capecitabine twice daily for 7 d. Blood, tumor, and adjacent healthy tissue samples were collected. The concentrations of capecitabine and its metabolite 5-FU were determined by HPLC. The concentration-time profiles of capecitabine and 5-FU were fitted by pharmacokinetic model. The tissue distribution factors for capecitabine and 5-FU, and the AUC ratios of 5-FU to capecitabine in plasma, tumor or adjacent healthy tissue, were calculated with pharmacokinetic parameters, respectively. Results The Ka of capecitabine was 1.17 h^-1 in plasma, 0. 46 h^-1 in tumor tissue, and 0. 61 h^-1 in healthy tissue. The AUCs of capecitabine were 2. 557 1 μg·mL^-1 ·h, 1. 629 2 μg·g^-1·h and 2. 085 0 μg·g^-1· h, and T1/2 was 0. 782 3 h, 1. 528 1 h and 1. 289 6 h in plasma, tumor, and healthy tissue, respectively. The AUCs of 5-FU were 0.418 7 μg·mL^-1 h, 1.671 7 μg·g^-1·h and 1.020 8 μg·g^-1·h; the T1/2 was 0. 631 3 h ,1.204 1 h and 1.031 2 h in plasma, tumor, and healthy tissue, respectively. The tissue distribution factors of capecitabine were 0. 637 1 in tumor (AUCcap-Tumor/AUCcap-plasma) and 0. 851 4 in healthy tissue (AUCcap-HT/AUCcap-plasma . The tissue distribution factors of 5-FU were 3. 992 6 in tumor (AUC5-FU-Tumor/AUC5-FU-plasma) and 2. 438 0 in healthy tissue (AUC5-FU-HT/AUC5-FU-plasma). The AUC ratios of 5-FU to capecitabine were 0. 1637, 1. 0261, and 0. 489 5 in plasma, tumor, and healthy tissue, respectively. Conclusion The simulation curves for the disposition of capecitabine and its metabolite 5-FU in plasma and tissue basically describe the activation process of capecitabine metabolizing to 5-FU and 5-FU elimination. There are similar distributions for capecitabine in plasma, tumor, and healthy tissue. The exposure of 5-FU in tumor was found to be 3. 992 6 times greater than that in plasma and 2. 438 0 times greater than that in healthy tissue. Capecitabine may metabolize preferentially to 5- FU in tumor tissue after oral administration. 展开更多

Background:Both hormonal therapy(HT) and maintenance capecitabine monotherapy(MCT) have been shown to extend time to progression(TTP) in patients with metastatic breast cancer(MBC) after failure of taxanes and anthracycline?containing regimens.However,no clinical trials have directly compared the efficacy of MCT and HT after response to first?line capecitabine?based combination chemotherapy(FCCT) in patients with hormone receptor(HR)?positive and human epidermal growth factor receptor 2(HER2)?negative breast cancer.Methods:We retrospectively analyzed the charts of 138 HR?positive and HER2?negative MBC patients who were in non?progression status after FCCT and who were treated between 2003 and 2012 at the Cancer Institute and Hospital,Chinese Academy of Medical Sciences,in Beijing,China.The median number of first?line chemotherapy cycles was 6(range,4–8);combined agents included taxanes,vinorelbine,or gemcitabine.Of these 138 patients,79 received MCT,and 59 received HT.Single?agent capecitabine was administered at a dose of 1250 mg/m2 twice daily for 14 days,followed by a 7?day rest period,repeated every 3 weeks.Of the 59 patients who received HT,37 received aromatase inhibitors(AIs),8 received selective estrogen receptor modulators(SERMs),and 14 received goserelin plus either AIs or SERMs.We then compared the MCT group and HT group in terms of treatment efficacy.Results:With a median follow?up of 43 months,patients in the HT group had a much longer TTP than patients in the MCT group(13 vs.8 months,P ease?free surviv= 0.011).When TTP was adjusted for age,menopausal status,Karnofsky performance status score,disal,site of metastasis,number of metastatic sites,and response status after FCCT,extended TTP was still observed for patients in the HT group(hazard ratio:0.63;95% confidence interval:0.44–0.93;P = 0.020).We also observed a trend of overall survival advantage for patients in the HT group vs.patients in the MCT group,but the difference was not significant(43 vs.37 months,P tients in the MCT g= 0.400).In addition,patients in the HT group gen?erally tolerated the treatment well,whereas paroup experienced grades 3–4 adverse events,the most frequent of which were hand?foot syndrome(15.8%) and hematologic abnormalities(7.6%).Conclusion:For HR?positive and HER2?negative MBC patients,HT might be considered a treatment after response to FCCT but prior to MCT as a long?term administration. 展开更多

Vacuum ultraviolet (VUV) photoionization and dissociative photoionization of capecitabine and its metabolites, 51-deoxy-5-fiuorocytidine (5'-DFCR) and 51-deoxy-5- fiuorouridine (5'- DFUR), were investigated with infrared laser desorption/tunable synchrotron VUV photoionization mass spectrometry. Molecular ions (M+) with small amounts of fragments can be found for these compounds at relatively low photon energies, while more fragment ions would be produced by increasing the photon energies. (M-H2O)+, (base+H)+, (base+2H)+, (base+30)+, (base+60)+, and sugar moiety were proposed for these nucleoside drugs with similar backbones. Decomposition channels for the major fragments were discussed in detail. Moreover, ab initio calculations were introduced to study the dehydration pathways of three fluoro-nucleosides. Corresponding appearance energies for the (M-H2O)+ ions were computed. 展开更多

Objective: To evaluate the role of class III β-tubulin (TUBB3), thymidylate synthase (TS), thymidine phosphorylase (TP), and excision repair cross-complementing group 1 (ERCC1) in clinical outcome of advanced gastric cancer patients receiving capecitabine plus paclitaxel or cisplatin. Methods: The clinical data and tumor specimens from 57 advanced gastric cancer patients receiving first-line capecitabine plus paclitaxel (cohort 1, n=36) and capecitabine plus cisplatin (cohort 2, n=21) were retrospectively collected, and TUBB3, TS, TP, and ERCC1 expressions were detected by real-time quantitative PCR. The associations between expressions of biomarkers and response or survival were analyzed statistically. Results: The median age of 57 patients was 57 years (range: 27–75 years) with 38 males and 19 females. Of all patients, the response rates of patients with high TP, low TP and high TS, low TS expressions were 57.1%, 27.6% (P=0.024), and 55.2%, 28.6% (P=0.042), respectively. Among cohort 1, the response rates and median overall survivals of patients with low and high TUBB3 expressions were 61.1% vs. 33.3% (P=0.095) and 13.8 months vs. 6.6 months (P=0.019), respectively; the response rate (87.5%) of patients with low TUBB3 and high TP expressions was higher than that (14.3%) of patients with high TUBB3 and low TP expressions (P=0.01). Among cohort 2, the response rates of patients with low ERCC1 and high ERCC1 expressions were 45.5% and 20.0% respectively (P=0.361). Conclusion: TUBB3, TS and TP expressions could predict the response of advanced gastric cancer patients receiving capecitabine-based and paclitaxel-based chemotherapy. These results will be further confirmed in future large samples. 展开更多

METHODS:Forty six patients with previously untreated,locally-advanced or metastatic colorectal cancer(mCRC) were recruited between 2001-2006 in a prospective open-label phaseⅡtrial,in German community-based outpatient clinics.Patients received a standard capecitabine plus irinotecan(CAPIRI) or CAPIRI plus bevacizumab(CAPIRI-BEV) regimen every 3 wk. Dose reductions were mandatory from the first cycle in cases of>grade 2 toxicity.The treatment choice of bevacizumab was at the discretion of the physician.Theprimary endpoints were response and toxicity and secondary endpoints included progression-free survival and overall survival. RESULTS:In the CAPIRI group vs the CAPRI-Bev group there were more female than male patients(47% vs 24%) ,and more patients had colon as the primary tumor site(58.8%vs 48.2%) with fewer patients having sigmoid colon as primary tumor site(5.9%vs 20.7%) .Grade 3/4 toxicity was higher with CAPIRI than CAPIRI-Bev:82%vs 58.6%.Partial response rates were 29.4%and 34.5%,and tumor control rates were 70.6%and 75.9%,respectively.No complete responses were observed.The median progression-free survival was 11.4 mo and 12.8 mo for CAPIRI and CAPIRI-Bev,respectively.The median overall survival for CAPIRI was 15 mo(458 d) and for CAPIRI-Bev 24 mo(733 d) .These differences were not statistically different.In the CAPIRI-Bev,group,two patients underwent a full secondary tumor resection after treatment,whereas in the CAPIRI group no cases underwent this procedure. CONCLUSION:Both regimens were well tolerated and offered effective tumor growth control in this outpatient setting.Severe gastrointestinal toxicities and thromboembolic events were rare and if observed were never fatal. 展开更多

AIM: To investigate the efficacy and safety of capecitabine and oxaliplatin (CapeOx) for extrahepatic metastasis after local treatment of hepatocellular carcinoma (HCC). METHODS: Thirty-two patients with extrahepatic metastasis of HCC after local treatment were prospectively enrolled. The CapeOx regimen consisted of capecitabine 1000 mg/m 2 taken orally twice daily on days 1-14, and oxaliplatin was administered at a total dose of 100 mg/m 2 on day 1. The treatment was repeated every 3 wk until disease progression or unaccetablle toxicity. Efficacy and safety were assessable for all enrolled patients. The primary objective of this study was to assess the overall response rate. The secondary objectives were to evaluate the overall survival (OS), the time to tumor progression (TTP) and the toxicity profile of the combined strategy. TTP and OS were assessed by the Kaplan-Meier method and differences between the curves were analyzed using the log-rank test. The statistical software SPSS version 15.0 for Windows (SPSS Inc., Chicago, IL, United States) was used for statistical analysis. All P values were 2-tailed, with statistical significance defined byP ≤ 0.05. RESULTS: Thirty-two patients were assessable for efficacy and toxicity. The median follow-up duration was 15 mo (range, 12-20 mo). At the cut-off date of March 31, 2012, 27 patients died due to tumor progression and one patient died of myocardial infarction. Four patients were still alive (three patients with disease progression). OR was 21.9% (n = 7), the stabilization rate was 40.6% (n = 13), and the disease control rate was 62.5%. The responses lasted from 4 to 19 mo (median, 6 mo). Median TTP was 4.2 mo (95%CI: 2.5-7.4), and the median OS time was 9.2 mo (95%CI: 6.5-17.8). The 1-year survival rate was 43.6% (95%CI: 29.0-66.0). In a multivariate analysis, OS was significantly longer in patients with a Child-Pugh class A compared with class B patients (P = 0.014), with a median OS of 10.1 mo vs 5.4 mo, and there were trends towards longer OS (P = 0.065) in patients without portal vein tumor thrombosis. There were no significant effects of age, gender, performance status, cirrhosis, metastatic sites, and level of alpha fetoprotein (AFP) or hepatitis B virus-DNA on OS. Among the 22 patients with elevated AFP levels at baseline (≥ 400 ng/mL), the level fell by more than 50% during treatment in 6 patients (27.3%). The most frequent treatment-related grade 3 to 4 toxicities included leucopenia/neutropenia, transient elevation of aminotransferases, handfoot syndrome and fatigue. CONCLUSION: CapeOx showed modest anti-tumor activity in metastatic HCC. However, the manageable toxicity profile and the encouraging disease control rate deserve further study for these patients. 展开更多

Objective: To investigate the efficacy and safety of capecitabine maintenance therapy(MT) after initial capecitabine plus docetaxel(XT) chemotherapy in patients with metastatic triple-negative breast cancer(m TNBC).Methods: Fifty-five m TNBC patients treated with XT chemotherapy between May 2007 and June 2013 were retrospectively analyzed. When initial disease control was achieved by the combination chemotherapy, capecitabine was continued for 32 patients(MT), while 23 patients remained without any treatment(nonMT). We compared progression-free survival(PFS) and safety of both groups.Results: The median PFS of 55 patients was 8.1 months, overall median PFS time of 32 patients in the capecitabine MT group and 23 in the non-MT group was 10.1 vs. 6.7 months(P=0.032), respectively. When compared PFS time of maintenance treatment, single-agent capecitabine prolonged PFS by 7.1 months, for non-MT patients, the PFS without any treatment was 3.1 months, and this between-group difference was statistically significant(P=0.003). Adverse events, including of hematologic toxicity, gastrointestinal toxicities, hand-foot syndrome and abnormal liver function were not significantly different between two groups.Conclusions: After initial disease control was achieved with the XT combination chemotherapy, capecitabine MT can significantly prolong PFS time with a favorable safety profile in m TNBC patients. 展开更多

To improve long-term outcomes, perioperative chemotherapies are combined with surgery. Human epidermal growth factor receptor 2 (HER2) overexpression had been noted in gastric cancer; therefore, trastuzumab has been used occasionally in this setting. A 63-year-old male Chinese patient, who was diagnosed with adenocarcinoma in the gastric antrum, as well as lymph node metastases along the left gastric and hepatic artery, and left adrenal area, was admitted to our hospital. HER2 expression was positive, and cluster amplification was detected in a fluorescence in situ hybridization assay. The patient received three cycles of a neoadjuvant trastuzumab/oxaliplatin /capecitabine regimen. He subsequently underwent distal gastrectomy, D2+ lymphadenectomy, left adrenalectomy, cholecystectomy and Billroth II anastomosis. Treatment was continued with another five postoperative cycles of the same medication and trastuzumab application for 1 year. No recurrence has been observed 18 mo after the operation. Trastuzumab as perioperative and adjuvant medication, in combination with oxaliplatin and capecitabine for a HER2-overexpressing advanced gastric adenocarcinoma, led to recurrence-free survival of at least 18 mo after surgery. 展开更多

Capecitabine (Xeloda) is an oral fluoropyrimidine which is produced as a pro-drug of fluorouracil, and shows improved tolerability and intratumor drug concentrations following its tumor-specif ic conversion to the active drug. We have searched the Pubmed and Cochrane databases from 1980 to 2009 with the purpose of reviewing all available information on Capecitabine, focusing on its clinical effectiveness against colorectal cancer. Special attention has been paid to trials that compared Capecitabine with standard folinic acid (leucovorin, LV)-modulated intravenous 5-fluorouracil (5-FU) bolus regimens in patients with metastatic colorectal cancer. Moreover the efficacy of Capecitabine on metastatic colorectal cancer, either alone or in various combinations with other active drugs such as Irinotecan and Oxaliplatin was also assessed. Finally, neoadjuvant therapy con- sisting of Capecitabine plus radiation therapy, for locally advanced rectal cancer was analysed. This combination of chemotherapy and radiotherapy has a special role in tumor down staging and in sphincter preservation for lower rectal tumors. Comparative trials have shown that Capecitabine is at least equivalent to the standard LV-5-FU combination in relation to progression-free and overall survival whilst showing a better tolerability prof ile with a much lower incidence of stomatitis. It is now known that Capecitabine can be combined with other active drugs such as Irinotecan and Oxaliplatin. The combination of Oxaliplatin with Capecitabine represents a new standard of care for metastatic colorectal cancer. Combinating the Capecitabine-Oxaliplatin regimen with promising new biological drugs such as Bevacizumab seems to give a realistic prospect of further improvement in time to progression of metastatic disease. Moreover, preoperative chemo-radiation using oral capecitabine is better tolerated than bolus 5-FU and is more effective in the promotion of both down-staging and sphincter preservation in patients with locally advanced rectal cancer. Finally, the outcomes of recently published trials suggest that capecitabine seems to be more cost effective than other standard treatments for the management of patients with colorectal cancer. 展开更多
