Abstract
PURPOSE Important developments in chemotherapy for advanced colorectal cancer over the past 15 years are reviewed, with an emphasis on the most recently published data from clinical trials of newer multidrug regimens, administration techniques, and dosing schedules. SUMMARY Eight agents are approved by the Food and Drug Administration (FDA) for use in treating patients with advanced colorectal cancer. Fluorouracil and leucovorin still constitute the foundation of most chemotherapy regimens for this population; combination fluorouracil-leucovorin therapy plus either irinotecan (the FOLFIRI regimen) or oxaliplatin (the FOLFOX regimen) are two firmly established first-line treatments shown to produce similar outcomes. In Phase III trials conducted over the past six to seven years, regimens of capecitabine plus oxaliplatin (CapeOx) were demonstrated to have clinical effectiveness comparable to that of FOLFOX therapy. Response rates of 35-55% and median overall survival of ≥20 months have been documented with some of the newer regimens. Research to define the optimal role of the three monoclonal antibody agents approved by FDA for use in managing advanced colorectal cancer is ongoing; bevacizumab has been shown to confer significant survival benefits when added to certain chemotherapy regimens, and other monoclonal antibodies (cetuximab and panitumumab) also appear to offer significant benefits in select patients as first- or second-line therapies. CONCLUSION Over the past 15 years, a shift toward multiagent treatment strategies including a variety of chemotherapy agents and monoclonal antibodies has yielded improved rates of response and prolonged survival among patients with advanced colorectal cancer. The CapeOx, FOLFOX, and FOLFIRI regimens are currently among the most widely used first-line treatments.

Capecitabine plus oxaliplatin compared with 5-fluorouracil plus oxaliplatin in metastatic colorectal cancer: Meta-analysis of randomized controlled trials. Oncol Lett 2012; 3:831-838. [PMID: 22741002 DOI: 10.3892/ol.2012.567] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2011] [Accepted: 01/04/2012] [Indexed: 12/27/2022] Open
Abstract
The aim of this study was to evaluate the curative effects and safety of capecitabine plus oxaliplatin compared with 5-fluorouracil (5-FU) plus oxaliplatin in patients with metastatic colorectal cancer (MCRC). We searched the Cochrane Central register of Controlled Trials (CENTRAL), PubMed, Ovid, ScienceDirect, EBSCO, EMBASE and conference proceedings for eligible trials. A meta-analysis was performed using Review Manager 5.0. A total of 3,603 cancer patients from 7 trials were analyzed, and the baseline patient characteristics were comparable in all studies. Curative effect outcomes including complete response (CR) (OR=0.78; 95% CI 0.47-1.31; p=0.35), partial response (PR) (OR=0.81; 95% CI 0.65-1.00; p=0.05) and the overall response rate (ORR) (OR=0.85; 95% CI 0.71-1.02; p=0.08) showed similar curative effects between the capecitabine plus oxaliplatin group and the 5-FU plus oxaliplatin group. Moreover, the median overall survival (OS) and progression-free survival (PFS) had no statistically significant differences. Regarding safety, hand-foot syndrome was more frequently observed in the capecitabine plus oxaliplatin group (OR=2.71; 95% CI 2.04-3.61; p<0.00001), while stomatitis and neutropenia were reversed. Other toxic effects had no statistically significant differences between the two groups. Our results showed that capecitabine plus oxaliplatin had similar curative effects to 5-FU plus oxaliplatin, however, it was safer in patients with MCRC.

A phase II study of oxaliplatin, dose-intense capecitabine, and high-dose bevacizumab in the treatment of metastatic colorectal cancer. Clin Colorectal Cancer 2011; 10:210-6. [PMID: 21855046 DOI: 10.1016/j.clcc.2011.03.018] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2010] [Revised: 12/02/2010] [Accepted: 12/06/2010] [Indexed: 02/04/2023]
Abstract
BACKGROUND This study was designed to determine the efficacy and tolerability of a novel 2-week regimen of capecitabine, oxaliplatin (OHP), and bevacizumab in patients with chemo-naive advanced colorectal cancer. PATIENTS AND METHODS Nineteen patients with previously untreated advanced colorectal cancer received capecitabine at 1000 mg/m(2) twice a day on days 1-5 and days 8-12 of a 14-day cycle, and OHP at 85 mg/m(2) and bevacizumab at 10 mg/kg every 2 weeks. Because of unacceptable toxicities, the capecitabine dose was reduced to 850 mg/m(2). Thirty-one additional patients were treated at the lower capecitabine dose. Treatment continued until disease progression, persistent intolerable toxicity, or physician and/or patient discretion. RESULTS Overall, toxicities were better managed and tolerated at the 850 mg/-m(2) capecitabine dose. The most common treatment-related grade ≥ 3 toxicities were diarrhea and sensory neuropathy. In the first 19 subjects, the response rate was 63% (95% confidence interval [CI], 38%-84%) and 5 patients had stable disease; median progression-free survival (PFS) was 10.1 months (95% CI, 5.7-19.5 months). In the subsequent 31 patients, the response was 42% (95% CI, 25%-61%); 11 patients had stable disease and median PFS was 10.4 months (95% CI, 6.9-15.4); median overall survival was 24.8 months (95% CI, 12.9-39.7). CONCLUSIONS This novel regimen of capecitabine at 850 mg/m(2) twice a day on days 1-5 and days 8-12 and OHP at 85 mg/m(2)and bevacizumab at 10 mg/kg every 14 days is clinically active in advanced colorectal cancer. The toxicity profile of this regimen is consistent with the standard every-3-week dosing schedule.

Abstract
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-specific 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 consisting 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 profile 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.

Abstract
Capecitabine is currently the only novel, orally home-administered fluorouracil prodrug. It offers patients more freedom from hospital visits and less inconvenience and complications associated with infusion devices. The drug has been extensively studied in large clinical trials in many solid tumors, including breast cancer, colorectal cancer, gastric cancer, and many others. Furthermore, the drug compares favorably with fluorouracil in patients with such cancers, with a safe toxicity profile, consisting mainly of gastrointestinal and dermatologic adverse effects. Whereas gastrointestinal events and hand-foot syndrome occur often with capecitabine, the tolerability profile is comparatively favorable. Prompt recognition of severe adverse effects is the key to successful management of capecitabine. Ongoing and future clinical trials will continue to examine, and likely expand, the role of capecitabine as a single agent and/or in combination with other anticancer agents for the treatment of gastrointestinal as well as other solid tumors, both in the advanced palliative and adjuvant settings. The author summarizes the current data on the role of capecitabine in the management of gastrointestinal cancers.

Abstract
Significant advancements in chemotherapy for metastatic colorectal cancer (mCRC) have been achieved over the past decade, and the median overall survival duration is now close to 24 months with appropriate treatment. The most widely recommended chemotherapy regimens are based on the use of irinotecan or oxaliplatin in combination with 5-fluorouracil and leucovorin; some data suggest further benefit with the addition of the targeted agents bevacizumab or cetuximab. Colorectal cancer primarily affects the elderly; however, much of the defining clinical research in this field has excluded subjects of advanced age or with a poor performance status, making it difficult for clinicians to interpret current treatment paradigms for their older patients. Most clinical trials that have included elderly patients document similar survival rates and toxicity profiles to those seen in younger patients. Moreover, survey data suggest that >70% of elderly patients with cancer are willing to undergo strong, palliative chemotherapy. While these findings suggest that age itself should not determine candidacy for chemotherapy, it is important to note the great heterogeneity of the elderly population with regard to overall health, independence, and performance status. The use of a comprehensive geriatric assessment is recommended to evaluate chemotherapy appropriateness. The management of frail elderly patients and those with a short life expectancy should be focused on palliation, while fit elderly patients can receive aggressive therapy in a similar fashion to younger patients.

Abstract
Xeloda (capecitabine), a thymidine phosphorylase activated fluoropyrimidine carbamate, is currently the only universally approved orally administered 5-fluorouracil (5-FU) prodrug. It belongs to a newer generation of orally administered fluoropyrimidines. It has been developed because of the clinical need for efficient, tolerable and convenient agents, which do not require continuous infusion. Capecitabine is not a cytotoxic drug in itself, but via a three-step enzymatic cascade, it is converted to 5-FU mainly within human cancer cells. While the drug compares favorably with 5-FU in patients with advanced or metastatic colorectal cancer and pretreated breast cancer, it also has an improved toxicity profile, mainly of gastrointestinal and dermatologic effects with a significantly lower incidence of grade 3/4 myelotoxicity compared with infusional 5-FU-based chemotherapy. Capecitabine's selective activation within the tumor allows for less systemic toxicity events. A gradient of fluoropyrimidine toxicity is observed: high in the US and low in East Asia. In addition, there is a discrepancy in tolerance of dose among patients treated in the US vs. Europe. Although patients can take the drug orally in the convenience of their own home, the key to successful management of capecitabine is the clinician's awareness of its severe, but low in incidence, adverse effects, and the patients' education, emphasizing compliance with the treatment plan, prevention and timely recognition of its toxicities.

Abstract
Capecitabine (Xeloda) was developed as a pro-drug of fluorouracil (FU), with the aim of improving tolerability and intratumor drug concentrations through its tumorspecific conversion to the active drug. The purpose of this paper is to review the available information on capecitabine, focusing on its clinical effectiveness against various carcinomas. Identification of all eligible English trails was made by searching the PubMed and Cochrane databases from 1980 to 2007. Search terms included capecitabine, Xeloda and cancer treatment. Nowadays, FDA has approved the use of capecitabine as a first line therapy in patients with metastatic colorectal cancer when single-agent fluoropyrimidine is preferred. The drug is also approved for use as a single agent in metastatic breast cancer patients who are resistant to both anthracycline and paclitaxel-based regimens or when further anthracycline treatment is contraindicated. It is also approved in combination with docetaxel after failure of prior anthracycline-based chemotherapy. In patients with prostate, pancreatic, renal cell and ovarian carcinomas, capecitabine as a single-agent or in combination with other drugs has also shown benefits. Improved tolerability and comparable efficacy, compared with the intravenous FU/LV combination, in addition to its oral administration, make capecitabine an attractive option for the treatment of several types of carcinomas.

Abstract
PURPOSE Oxaliplatin combined with either fluorouracil/leucovorin (OXAFAFU) or capecitabine (OXXEL) has a demonstrated activity in metastatic colorectal cancer patients. We aimed at comparing these two regimens in terms of response rate (RR), safety, progression-free survival (PFS), and quality of life (QoL) of patients. METHODS A total of 322 patients with metastatic colorectal cancer were randomized to receive biweekly: oxaliplatin 100 mg/m(2) i.v. on day 1, capecitabine 1,000 mg/m(2) orally twice daily from day 1 to day 11 (OXXEL); or oxaliplatin 85 mg/m(2) i.v. on day 1; 6S-leucovorin 250 mg/m(2) i.v. and fluorouracil 850 mg/m(2) i.v. on day 2 (OXAFAFU). RESULTS Eleven complete and 42 partial responses were registered with OXXEL (RR = 34%); six complete and 48 partial responses were obtained with OXAFAFU (RR = 33%) (P = 0.999). Severe adverse events were less frequent (32 vs. 43%) with OXXEL, which also reduced the occurrence of severe neutropenia (10 vs. 27%) and febrile neutropenia (6 vs. 13%), but produced more gastric side effects (8 vs. 3%) and diarrhea (13 vs. 8%). QoL did not differ across the two arms. Median PFS was 6.6 months in the OXXEL, and 6.5 months in the OXAFAFU arm (HR = 1.12, P = 0.354). Median overall survival was 16.0 and 17.1 months (HR = 1.01, P = 0.883). CONCLUSIONS OXXEL and OXAFAFU regimens were equally active in metastatic colorectal cancer. The choice should be based on patient preference and on pharmacoeconomic evaluations.

Abstract
OBJECTIVE This study was designed as a multicentre phase II trial to assess the efficacy and safety of gefitinib in association with capecitabine and oxaliplatin in patients with untreated metastatic colorectal cancer. RESEARCH DESIGN AND METHODS Patients with metastatic colorectal cancer that had received no prior chemotherapy for advanced disease were treated with oral gefitinib (250 mg daily) plus oral capecitabine (1000 mg/m2 twice a day on Days 1-14) and intravenous oxaliplatin (120 mg/m2 on Day 1 of each 3-week cycle). RESULTS Thirty-five patients were enrolled. In the intention-to-treat analysis, 3 (8.6%) patients experienced a complete response (CR), 14 (40%) a partial response (PR) and 11 (31.4%) had stable disease (SD). The disease control rate (CR + PR + SD) was 80%, the median time to progression was 7.3 months (95%CI: 4.76-9.2) and the estimated median overall survival was 21.9 months (95% CI: 15.1--not reached). The most common grade 3 to 4 toxicities included diarrhoea (31%) and vomiting (5.7%). CONCLUSIONS The combination of capecitabine, oxaliplatin and gefitinib appears to have promising activity in chemotherapy-naïve metastatic colorectal cancer. A higher disease control rate and an increase in median overall survival were seen compared with previous reports with capecitabine and oxaliplatin in similar patient populations. The tolerability profile appears to be predictable and similar to capecitabine/oxaliplatin regimens.

Abstract
Medullary thyroid carcinoma with distant metastases is generally incurable, with 20% overall survival at 10 years. The treatment goal is palliative. Chemotherapy has a limited role, with low response rates and high toxicities with the different regimens. Here, we report the case of 64-year-old man with metastatic medullary thyroid carcinoma in progression after primary treatment with cisplatin-doxorubicin. The patient received capecitabine 2000 mg/m total per day x 14 days followed by 1-week rest. He received 41 cycles, and presented prolonged and objective tumor response (30 months), without any toxicity.

Abstract
PURPOSE The purpose of this study was to evaluate the possible use of changes in apparent diffusion coefficient (ADC) measured by magnetic resonance imaging for pretreatment prediction and early detection of tumor response in a mouse model during fractionated chemoradiotherapy. MATERIALS AND METHODS Athymic mice with bilateral HT29 xenografts on rear flanks were allocated into three groups: control, capecitabine, and capecitabine and oxaliplatin. The left flanks of the mice received daily irradiation. T2 and diffusion images were acquired before therapy and weekly for the following 9 weeks. Pretreatment and changes in ADC were calculated and compared with tumor doubling growth delay. RESULTS No correlations between pretreatment ADC and changes in tumor volumes after therapy were seen. All treated tumors, except those receiving capecitabine (P = .06), showed increased mean tumor ADC values 11 days after initialization of therapy (P < .05) before returning to pretreatment values within 5 days posttherapy (day 18 after onset of therapy). This increase in mean tumor ADC showed a strong positive correlation (r = 0.92, P < .01) with mean tumor doubling growth delay. CONCLUSIONS Pretreatment ADC values did not predict the effectiveness of therapy, whereas early changes in mean ADC quantitatively correlated with treatment outcome.

Abstract
OBJECTIVE To report and discuss the results of clinical trials published concerning chemotherapy for metastatic colorectal cancer in order to elucidate and define treatment guidelines. METHOD The biomedical and pharmaceutical database EMBASE was searched for phase-II and -III clinical trials or metaanalysis that examined chemotherapy for mCRC (January 1998-January 2006). RESULTS 5-fluorouracil still maintains its preponderant role after 40 years, and its modulation by adding folinic acid or administering it in more prolonged infusions has managed to slightly increase survival in these patients, as well as to improve the drug s toxicity profile. The development of irinotecan first, and then oxaliplatin has lengthened survival by a few months when in combination with 5-fluorouracil and folinic acid-based regimens. All patients should have access to these two drugs guaranteed during the course of the disease, as it will increase survival. Raltitrexed fails to improve survival, and also diminishes quality of life in these patients; hence its use has been relegated to clinical trials. Bevacizumab, combined with classic chemotherapy regimens, attains slightly longer survivals. Results from studies with cetuximab are not that conclusive, and its use should be restricted to patients with relapsing disease after irinotecan and no other treatment options left. CONCLUSIONS New drugs for metastatic colorectal cancer open up new therapy lines allowing increasingly improved survival. However, optimal schemes, as well as their order of administration, have yet to be fully devised.

Abstract
UNLABELLED This phase II randomised trial compares oxaliplatin plus protracted infusion of 5-fluorouracil (pviFOX) or oxaliplatin plus capecitabine (XELOX) in the first-line treatment of advanced colorectal cancer (ACRC). METHODS From December 2001 to March 2005, 118 patients were randomised to arm A (pviFOX: pvi5-FU by a central venous catheter 250 mg/m2/daily d1-21+oxaliplatin 130 mg/m2 d1 q3w) (56 pts) or arm B (XELOX: capecitabine 1000 mg/m2 po bid d1-14+oxaliplatin at the same schedule) (62 pts). RESULTS Patient characteristics were well-balanced between the two arms. Median number of complete cycles was six. The objective responses were: CR 1 (1.7%) and 3 (4.8%), PR 26 (46.4 %) and 24 (38.7%), SD 13 (23.2%) and 20 (32.3%), P 13(23.2%) and 10 (16.1%), not evaluable 3 (5.4%) and 5 (8.1 %) in arms A and B, respectively; the CR+PR rate was 48.2% (95% confidence limits 34.6%-61.9%) versus 43.5 % (31.0%-56.7%). Median TTP was 7 versus 9 months, respectively. About 50% of the patients with symptoms or low performance status at baseline experienced improvement without major differences between the two arms. G3-4 diarrhoea was observed in 14.0% versus 8.2%, G3 stomatitis in 3.7% versus 0, and G3 neurotoxicity in 18.5% versus 24.6% in arms A and B, respectively. Eight patients in arm A (14.8%) had venous line problems that obliged the temporary suspension (six cases) or stopping (two cases) of the 5-FU infusion. CONCLUSION Both pviFOX and XELOX are effective and safe first-line treatments for patients with ACRC. By avoiding intravenous (i.v.) administration by a central catheter, XELOX is favoured in clinical practice.

Abstract
BACKGROUND Results on overall survival in randomised studies of mono- versus combination chemotherapy in advanced colorectal cancer patients may have been biased by an imbalance in salvage treatments. This is the first randomised study that evaluates sequential versus combination chemotherapy with a fluoropyrimidine, irinotecan and oxaliplatin. PATIENTS AND METHODS A total of 820 patients were randomised between first-line capecitabine, second-line irinotecan and third-line capecitabine + oxaliplatin (arm A) versus first-line capecitabine + irinotecan, and second-line capecitabine + oxaliplatin (arm B). The primary end point was overall survival. We present the results of an interim analysis on the safety data in the first 400 patients. RESULTS In first-line the incidence of grade 3-4 diarrhoea, nausea, vomiting and febrile neutropenia was significantly higher in arm B. However, when toxicity over all lines was considered only grade 3 hand-foot syndrome occurred more frequently in arm A (12% versus 6%, respectively, P = 0.041). The incidence of cardiovascular toxicity was low. In two out of five patients with sudden death (one in arm A, four in arm B) cardiovascular risk factors were present. CONCLUSIONS Both treatment arms had an acceptable safety profile. These data imply that the results on survival will be the major determinant for the selection of either strategy. Capecitabine plus irinotecan appears to be a feasible first-line treatment for patients with advanced colorectal carcinoma.

Abstract
BACKGROUND The combination of 5-fluorouracil (5-FU), leucovorin (LV), and oxaliplatin (I-OHP) was shown to be both more active against metastatic colorectal carcinoma and better tolerated if the drug delivery rate was chronomodulated according to circadian rhythms rather than constant. The aim of the present study was to define the feasibility and efficacy of XELOX administered through a new chronomodulated schedule in untreated advanced colorectal cancer (CRC) patients. METHODS Chemotherapy-naive patients with advanced CRC were considered eligible for the study accrual. TREATMENT oxaliplatin 70 mg/m(2) continuous infusion (c.i.) for 12 h (8:00 a.m. to 8:00 p.m.) days 1, 8 plus chronomodulated oral capecitabine 1,750 mg/m(2)/die (h 8:00 a.m. 25% of total dose; h 6:00 p.m. 25% of total dose; h 11:00 p.m. 50% of total dose), days 1-14 every 21 days. RESULTS Forty-six patients were evaluated for safety and efficacy (male/female, 20/26). Median age was 64 years (range 28-77 years). Median Eastern Cooperative Oncology Group performance status (PS) was 0 (range 0-1). A total of 324 cycles have been administered: median per patient 6 (range 3-10 courses). Median number of metastatic sites was 1. Metastatic sites distribution was as follows: liver (65.2%), lung (34.8%), and nodes (32.6%). Median follow-up was 14 months (range 6.0-40.3 months). In an intent-to-treat efficacy analysis, objective response and stable disease were recorded in 27 (58.6%) and in 16 patients (34.9%), respectively. The median response duration was 8.0 months (95% CI; 5.03-10.96 months). The median time to progression (TTP) was 9.0 months (95% CI; 6.47-11.52 months). The overall survival (OS) was not reached, with a median value > 24 months (95% CI; 23.66-36.30 months). The grade 3 toxicities were diarrhea (8.7%), liver toxicity (13.1%), fatigue (8.7%), neurotoxicity (2.2%), neutropenia (8.7%), and thrombocytopenia (2.2%). CONCLUSION This regimen resulted of particular interest for patients with untreated metastatic CRC.

Abstract
Metastatic colorectal cancer remains a public-health issue on a global scale. With development of a new generation of cytotoxic agents, survival has improved for patients with metastatic disease. How to maximize the benefit of chemotherapy with acceptable toxicity remains incompletely answered. Hepatic resection can provide a significant hope for long term survival, and a subset of patients might benefit from perioperative approaches. More recently, specific molecular processes have been targeted for therapeutic interventions, and encouraging results have been achieved using inhibitors of the Epidermal Growth Factor Receptor and the Vascular Endothelial Growth Factor.

Abstract
The purpose of this phase II trial was to determine the efficacy and safety of the XELOX (capecitabine/oxaliplatin) regimen as first-line therapy in the elderly patients with metastatic colorectal cancer (MCRC). A total of 50 patients with MCRC aged > or = 70 years received oxaliplatin 130 mg m(-2) on day 1 followed by oral capecitabine 1000 mg m(-2) twice daily on days 1-14 every 3 weeks. Patients with creatinine clearance 30-50 ml min(-1) received a reduced dose of capecitabine (750 mg m(-2) twice daily). By intent-to-treat analysis, the overall response rate was 36% (95% CI, 28-49%), with three (6%) complete and 15 (30%) partial responses. In total, 18 patients (36%) had stable disease and 14 (28%) progressed. The median times to disease progression and overall survival were 5.8 months (95% CI, 3.9-7.8 months) and 13.2 months (95% CI, 7.6-16.9 months), respectively. Capecitabine was well tolerated: grade 3/4 adverse events were observed in 14 (28%) patients: 11 (22%) diarrhoea, eight (16%) asthenia, seven (14%) nausea/vomiting, three (6%) neutropenia, three (6%) thrombocytopenia, and two (4%) hand-foot syndrome. There was one treatment-related death from diarrhoea and sepsis. In conclusion, XELOX is well tolerated in elderly patients, with respectable efficacy and a meaningful clinical benefit response. Given its ease of administration compared with combinations of oxaliplatin with 5-FU/LV, it represents a good therapeutic option in the elderly.

Abstract
Worldwide, colorectal cancer is a common cancer and a major cause of morbidity and mortality. Patients frequently present with, or later develop, metastatic disease. Median survival with supportive care alone is approximately 6 - 8 months. However, a number of recent developments have greatly increased the range of therapeutic options, improving median survival to > 20 months. Cytotoxic agents such as capecitabine, irinotecan and oxaliplatin are now established treatment strategies. In parallel, an improved understanding of tumour biology has led to the development of non-cytotoxic targeted therapies. Examples include bevacizumab (targeting tumour angiogenesis) and cetuximab (targeting the epidermal growth factor receptor). These agents have recently been incorporated into standard management. This paper reviews these and other advances in the care of patients with advanced colorectal cancer and discusses a number of agents that are currently under development.

Abstract
Capecitabine plus oxaliplatin every 3 weeks (XELOX regimen) has proven efficacy in patients with colorectal carcinoma. We investigated this combination in patients with previously untreated advanced gastric carcinoma. The study population comprised patients with histologically confirmed nonresectable advanced gastric adenocarcinoma. Patients received intravenous oxaliplatin 130 mg m(-2) over 2 h on day 1 plus oral capecitabine 1000 mg m(-2) twice daily on days 1-14, every 3 weeks. Patients received a maximum of eight cycles. Twenty evaluable patients (17 men, 3 women) with a median age of 64 years (range 38-75) were enrolled. The overall response rate was 65% (95% confidence interval (CI), 44-86%), with complete responses in two patients and partial responses in 11 patients. Median progression-free survival was 7.5 months (95% CI, 3.2-11.7 months); median overall survival was not reached during the study period. There was no grade 4 and little grade 3 toxicity. The most common haematological adverse event was anaemia (65% of patients) and the most common nonhaematological toxicities were vomiting (65%), neuropathy (60%), diarrhoea (30%), and hand-foot syndrome (20%). In conclusion, XELOX is apparently as effective as triplet combinations and is well tolerated as first-line therapy for advanced gastric carcinoma. We are starting a large multi-institutional phase II study of XELOX in this setting.

Abstract
BACKGROUND In patients with metastatic colorectal carcinoma (MCC), capecitabine has demonstrated a superior response rate (RR), equivalent disease progression-free (PFS) and overall survival (OS), and an improved overall tolerability profile compared with bolus 5-fluorouracil/leucovorin (5-FU/LV). The FOLFOX4 regimen, combining oxaliplatin with LV and bolus plus infusional 5-FU (LV5FU2), has been shown to improve RR and PFS versus LV5FU2, and it was more effective and less toxic than irinotecan plus bolus 5-FU/LV. Capecitabine (an oral fluoropyrimidine) may be an effective, well tolerated, and more convenient alternative to 5-FU/LV in combination with oxaliplatin, especially in older patients. METHODS Elderly (> or = 70 years) patients with MCC were treated with a 3-weekly regimen of oxaliplatin at an initial dose of 85 mg/m(2) intravenously on Day 1 plus capecitabine 1000 mg/m(2) orally twice daily from Days 2 to 15 (XELOX regimen). In the absence of Grade > or = 2 hematologic toxicity, oxaliplatin was increased to 100 mg/m(2) in the second cycle, and in the absence of Grade > or = 2 nonhematologic adverse events during Cycle 2, capecitabine was increased to 1250 mg/m(2) twice daily in the third and subsequent cycles. After the first 35 patients (first series), the treatment protocol was amended so that only an oxaliplatin increase to 110 mg/m(2) and 130 mg/m(2) during Cycles 2 and 3, respectively, was planned in the remaining 41 patients (second series). RESULTS Seventy-six patients with a median age of 75 years (range, 70-82 years) entered the current study. In the first series, the oxaliplatin dose was increased in 18 (51%) patients, and the capecitabine dose was increased in 4 (11%) patients. In the second series, the oxaliplatin dose was increased to 110 mg/m(2) in 26 (63%) patients, and to 130 mg/m(2) in 19 (46%) patients. In all, 2 complete and 29 partial responses were observed, for an overall RR of 41% (95% confidence interval [CI], 30-53%). The median PFS was 8.5 months (95% CI, 6.7-10.3 months), and the median OS was 14.4 months (95% CI, 11.9-16.9 months). In a multivariate analysis, the presence of disease symptoms affected both PFS and OS, whereas OS also was independently affected by male gender and disease spread. Age had no independent effect on PFS or OS. Five percent of patients developed Grade > or = 3 hematologic toxicity during treatment, Grade 3 peripheral neuropathy occurred in 8% of patients, and severe hand-foot syndrome in 13% of patients. CONCLUSIONS Fit elderly patients with MCC showed a good RR to XELOX with only mild toxicity observed in most patients. XELOX, should, therefore be considered as an important therapeutic option for elderly patients with MCC.

Abstract
Despite recent improvements in the treatment of metastatic colorectal cancer, few patients are cured and the response rates to second-line treatments are poor. Onyx-015, an oncolytic virus, was administered to patients with metastatic colorectal cancer by hepatic artery infusion. No dose-limiting toxicities were observed in the phase I/II studies. Onyx-015 can kill tumor cells by mechanisms that are distinct from chemotherapeutic agents and may therefore have activity among patients who have failed first-line chemotherapy. The 24 patients included in this analysis had failed first-line therapy with 5-FU/leucovorin, 79% of the patients failed two or more regimens and 58% had failed treatment with Irinotecan. Despite the extensive prior therapy, the median survival of these patients was 10.7 months, 46% were alive at 1 year and two patients (8%) had partial responses. In all, 11 patients (46%) had stable disease at the completion of the four planned viral treatments (3 months). The median survival of this group of patients was 19 months, suggesting that stable disease may be an important predictor of benefit with oncolytic viruses. Eight of the 11 patients with stable disease at 3 months demonstrated a unique radiographic pattern of transient enlargement of tumor masses (10-48%) after the initial infusions of Onyx-015, followed by radiographic evidence of extensive tumor necrosis and regression. The initial enlargement and subsequent tumor necrosis resulted in a prolonged time to achieve objective tumor regression. In addition, the transient enlargement of the tumor masses may have resulted in premature removal of responding patients. Treatment of eight patients was stopped prior to completion of the planned four treatments due to presumed progression as defined by standard radiographic criteria (>25% increase in tumor size). Functional imaging, such as positron emission tomography (PET) scans, may help distinguish clinical responses from progressive disease following treatment with oncolytic viruses. Onyx-015 may benefit patients with refractory colorectal cancer and additional studies that include PET scans to assess clinical response are warranted.

Abstract
Background New chemotherapy regimens for patients with colorectal cancer have improved survival, but at the cost of clinical toxicity. Oxaliplatin, an agent used in first-line therapy for metastatic colorectal cancer, causes acute and chronic neurotoxicity. This study was performed to carefully assess the incidence, type and duration of oxaliplatin neurotoxicity. Methods A detailed questionnaire was completed after each chemotherapy cycle for patients with metastatic colorectal cancer enrolled in a phase I trial of oxaliplatin and capecitabine. An oxaliplatin specific neurotoxicity scale was used to grade toxicity. Results Eighty-six adult patients with colorectal cancer were evaluated. Acute neuropathy symptoms included voice changes, visual alterations, pharyngo-laryngeal dysesthesia (lack of awareness of breathing); peri-oral or oral numbness, pain and symptoms due to muscle contraction (spasm, cramps, tremors). When the worst neurotoxicity per patient was considered, grade 1/2/3/4 dysesthesias and paresthesias were seen in 71/12/5/0 and 66/20/7/1 percent of patients. By cycles 3, 6, 9, and 12, oxaliplatin dose reduction or discontinuation was needed in 2.7%, 20%, 37.5% and 62.5% of patients. Conclusion Oxaliplatin-associated acute neuropathy causes a variety of distressing, but transient, symptoms due to peripheral sensory and motor nerve hyperexcitability. Chronic neuropathy may be debilitating and often necessitates dose reductions or discontinuation of oxaliplatin. Patients should be warned of the possible spectrum of symptoms and re-assured about the transient nature of acute neurotoxicity. Ongoing studies are addressing the treatment and prophylaxis of oxaliplatin neurotoxicity.

Abstract
BACKGROUND Capecitabine and oxaliplatin are both effective and well-tolerated monotherapies for the treatment of advanced colorectal cancer (CRC). Oxaliplatin has also been shown to be very effective when combined with 5-FU/LV in the first-line setting. AIM OF THE STUDY Assess the efficacy and safety of capecitabine plus oxaliplatin (XELOX) in patients with previously untreated advanced CRC. METHODS Fifty-three patients with measurable disease received capecitabine 1,000 mg/m2 twice daily on d 1-14 and oxaliplatin 130 mg/m2 on d 1, every 3 wk. Of these, 52 were evaluable for safety and 49 for antitumor response. RESULTS There was a low rate of grade 1/2 adverse events; grade 3/4 events included leukopenia (10%), neutropenia (6%), thrombocytopenia (2%), nausea/vomiting (4%), and diarrhea (4%). The overall response rate was 39% (95% CI, 25-54%) and median time to disease progression was 7.8 mo. CONCLUSIONS XELOX is an active and well-tolerated first-line treatment for advanced CRC. Randomized phase III studies are ongoing to compare XELOX with FOLFOX in view of the comparable efficacy and safety but superior convenience of XELOX therapy.

Abstract
OBJECTIVES The aim of the study was to define the feasibility and efficacy of Xelox (capecitabine and oxaliplatin) administered through a new and original schedule in advanced pretreated colorectal cancer (CRC) patients. METHODS 36 metastatic CRC patients resistant at least to a previous 5-fluorouracil- and irinotecan-based chemotherapy line were included in the study. TREATMENT Oxaliplatin 70 mg/m2 as continuous infusion for 12 h (8.00 a.m. to 8.00 p.m.) on days 1, 8 plus chronomodulated capecitabine 1,750 mg/m2/day per os (8.00 a.m. 25% of total dose; 6.00 p.m. 25% of total dose; 11.00 p.m. 50% of total dose), on days 1-14 every 21 days. 16 (44.4%) patients had previously received only 1 chemotherapy line for metastatic disease and 20 patients (55.6%) 2 chemotherapy lines. Moreover, 12 patients (33.3%) progressed after a first or second line of oxaliplatin-based regimen as well. RESULTS Most frequent related G3-4 adverse reactions were diarrhea (11.6%), nausea/vomiting (8.3%), neuropathy (8.3%), mucositis (8.3%), asthenia (16.7%) and hand-foot syndrome (5.5%). G3-4 anemia, leucopenia and liver toxicities were not observed. The overall response rate was 30.6% (11/36 patients). Disease stabilization was observed in 13 patients (36.1%) and progression in 12 patients (34.3%). Between the 12 oxaliplatin-resistant patients, the overall response rate was 25% (3 patients); 6 patients (54.5%) obtained a stable disease, and only 3 patients (25%) progressed. The median overall survival was 11.3 months (95% confidence interval 7.0-15.7 months), the median response duration 2.8 months (95% confidence interval 1.2-5.6 months) and the median time to progression 6.7 months (95% confidence interval 5.7-6.3 months). The 1-year survival rate was 53.8%. CONCLUSIONS The high overall tumor growth control, the remarkable median time to progression and overall survival and the good safety profile are of particular interest for patients with heavy pretreated metastatic CRC.

Abstract
Combination chemotherapy regimens including irinotecan and oxaliplatin markedly improve response rate and prolong median survival over fluorouracil with leucovorin (FU/LV), and have supplanted FU/LV as the standard systemic approach for metastatic colorectal cancer. The recent availability of five active chemotherapeutic agents has doubled the median overall survival for metastatic colorectal cancer from 10 to 20 months, and though the optimal strategy for incorporation of all drugs is still unclear, current data support the use of chemotherapy doublets in first-line rather than sequential single-agent therapy. Multidrug regimens increase both response rate and the proportion of patients able to undergo potentially curative resection. In addition, as many as 20% to 30% of patients never receive second-line chemotherapy. When used as single agents, bolus and infusional FU/LV and capecitabine are similarly effective but have differing toxicity. Chemotherapy combinations that incorporate infusion of FU are less toxic and more effective than those using bolus FU dosing. Capecitabine is under study as an alternative dosing method for use in combination regimens; however, the optimal dose has not been defined and final safety and efficacy outcomes are being addressed in ongoing phase II and III investigations. Three combinations have shown excellent first-line efficacy in phase III trials—IFL with bevacizumab, FOLFOX, and FOLFIRI—but neither of these combinations is clearly superior. Sound clinical judgment must continue to guide treatment decisions while we await data regarding the optimal combination and sequence of fluorouracil, irinotecan, oxaliplatin, bevacizumab, and cetuximab.

Abstract
Oxaliplatin 100 mg/m(2) iv on day 1, and capecitabine 1,000 mg/m(2) orally bid from day 1 (evening) to day 11 (morning) were administered every 2 weeks (OXXEL regimen) to 38 patients as first-line treatment for metastatic colorectal carcinoma. A total of 318 cycles were administered, with a median of 8 (range, 4-12) cycles per patient. Response rate (RR) was 45% (95% confidence interval (CI), 29%-62%), with 7 complete responses and 10 partial responses; furthermore, 12 patients showed a stable disease, so that a disease control was achieved in 29 (76%) patients. RR was greater among patients with performance status 0 (52%), without weight loss (52%), younger than 65 years (50%), and previously unexposed to adjuvant chemotherapy (48%), while no correlation was found with the actually delivered oxaliplatin dose intensity. Overall, haematological side effects were negligible, with no case of grade 4 toxicity, and only one patient suffering from an episode of grade 3 neutropenic fever. Severe anaemia occurred in 4 (11%) patients, and grade 3 neuropathy affected 9 (24%) patients. Median progression-free survival was 7.9 (95% CI, 6.2-9.6) months, and median overall survival has not been reached yet. In conclusion, the OXXEL regimen resulted safe and active, and it deserves further evaluation in metastatic colorectal cancer patients.

Abstract
BACKGROUND Irinotecan (IRI) and oxaliplatin (OXA) are effective in the treatment of colorectal cancer. Previously untreated patients with advanced colorectal carcinoma (CRC) were randomly assigned to receive IRI plus leucovorin (LV)/5-fluorouracil (5-FU), or OXA plus LV/5-FU in order to compare the response rates, time-to-tumor progression, overall survival rates, and toxicity profiles of these two agents. MATERIALS AND METHODS From January 1999 to February 2002, 295 patients were randomized to receive either IRI/LV/5-FU or OXA/LV/5-FU. The treatment schedules consisted of weekly IRI 70 mg/m(2) or OXA 45 mg/m(2) plus LV 200 mg/m(2) followed immediately by intravenous bolus 5-FU 450 mg/m(2) for 6 weeks, followed by a 2-week rest period. Treatment was continued for up to four cycles or until disease progression, unacceptable toxicity or patient refusal. RESULTS There were no significant differences between the study arms in the overall response rate (33% with IRI/LV/5-FU versus 32% with OXA/LV/5-FU based on responses demonstrated on a single evaluation; 23% with IRI/LV/5-FU versus 22.3% with OXA/LV/5-FU based on responses confirmed according to WHO criteria) median time to progression (8.9 versus 7.6 months), and median overall survival (17.6 versus 17.4 months). Toxicity profiles (grades 3 and 4) were similar in the IRI and OXA arms (diarrhea 12.3% and 9.8%, neutropenia 8.2% and 4.9%, and febrile neutropenia 1.4% and 1.4%, respectively), with the exception of grade 3 sensory neuropathy, which almost exclusively occurred in the OXA arm (0% versus 5.6%; P=0.003, Fisher's exact test). CONCLUSION The IRI/LV/5-FU and OXA/LV/5-FU regimens demonstrated equally substantial efficacies and manageable toxicity profiles in the first-line treatment of patients with advanced CRC. However, IRI/LV/5-FU may be the preferable regimen to avoid significant neurotoxicity associated with OXA-LV/5-FU.

Abstract
From September 2001 to November 2002, 35 patients aged 70-81 (median, 75) years, with measurable metastatic lesions from colorectal carcinoma, were treated with a combination of oxaliplatin (OXA) infused i.v. over 2 h on day 1, and capecitabine, assumed orally twice a day (12-h apart) from day 2 to day 15. An alternated dose escalation for both drugs was planned over the first three cycles for each patient, in the absence of WHO grade > or =2 toxicity on previous cycle: starting doses were 85 mg/m2 for OXA, and 2000 mg/m2 (day) for capecitabine on first cycle; on second cycle, OXA was planned at 100mg/m2, while capecitabine was planned at 2500 mg/(m2 day) on third cycle. Treatment was repeated every 3 weeks until progression, or for a maximum of 12 cycles. A total of 212 cycles were administered, with a median of 6 (range, 1-12) cycles/patient. Dose escalation was performed in 18 (51%) patients for OXA, and in 4 (11%) patients for capecitabine. No grade 4, and 10 (29%) cases of grade 3 toxicity of any type were reported. Abdominal symptoms (pain, nausea, or vomiting) affected 66% of patients, but they were of grade 3 in only 2 (6%) patients. Grade 3 diarrhoea occurred in 3 (9%) patients. Two complete and 12 partial responses (PR) were reported, for an overall response rate of 40% (95% CI, 24-58%). Progression of disease occurred in 23 (66%) patients, and 18 (51%) died. The actuarial median progression-free and survival time were 6.9 and 14.1 months, respectively.

Abstract
BACKGROUND Fluorouracil (FU) is an antimetabolite with activity against numerous types of neoplasms, including those of the breast, esophagus, larynx, and gastrointestinal and genitourinary tracts. Systemic toxicity, including neutropenia, stomatitis, and diarrhea, often occur due to cytotoxic nonselectivity. Capecitabine was developed as a prodrug of FU, with the goal of improving tolerability and intratumor drug concentrations through tumor-specific conversion to the active drug. OBJECTIVES The purpose of this article is to review the available information on capecitabine with respect to clinical pharmacology, mechanism of action, pharmacokinetic and pharmacodynamic properties, clinical efficacy for breast and colorectal cancer adverse-effect profile, documented drug interactions, dosage and administration, and future directions of ongoing research. METHODS Relevant English-language literature was identified through searches of PubMed (1966 to August 2004), International Pharmaceutical Abstracts (1977 to August 2004), and the Proceedings of the American Society of Clinical Oncology (January 1995 to August 2004). Search terms included capecitabine, Xeloda, breast cancer, and colorectal cancer. The references of the identified articles were reviewed for additional sources. In addition, product information was obtained from Roche Pharmaceuticals. Studies from the identified literature that addressed this article's objectives were selected for review, with preference given to Phase II/III trials. RESULTS Capecitabine is an oral prodrug that is converted to its only active metabolite, FU, by thymidine phosphorylase. Higher levels of this enzyme are found in several tumors and the liver, compared with normal healthy tissue. In adults, capecitabine has a bioavailability of approximately 100% with a Cmax of 3.9 mg/L, Tmax of 1.5 to 2 hr, and AUC of 5.96 mg.h/L. The predominant route of elimination is renal, and dosage reduction of 75% is recommended in patients with creatinine clearance (CrCl) of 30 to 50 mL/min. The drug is contraindicated if CrCl is < 30 mL/min. Capecitabine has shown varying degrees of efficacy with acceptable tolerability in numerous cancers including prostate, renal cell, ovarian, and pancreatic, with the largest amount of evidence in metastatic breast and colorectal cancer. Single-agent capecitabine was compared with IV FU/leucovorin (LV) using the bolus Mayo Clinic regimen in 2 Phase III trials as first-line treatment for patients with metastatic colorectal cancer. Overall response rate (RR) favored the capecitabine arm (26% vs 17%, P < 0.001); however, this did not translate into a difference in time to progression (TTP) (4.6 months vs 4.7 months) or overall survival (OS) (12.9 months vs 12.8 months). In Phase II noncomparative trials, combinations of capecitabine with oxaliplatin or irinotecan have produced results similar to regimens combining FU/LV with the same agents in patients with colorectal cancer. In metastatic breast cancer patients who had received prior treatment with an anthracycline-based regimen, a Phase III trial comparing the combination of capecitabine with docetaxel versus docetaxel alone demonstrated superior objective tumor RR (42% vs 30%, P = 0.006), median TTP (6.1 months vs 4.2 months, P < 0.001), and median OS (14.5 months vs 11.5 months, P = 0.013) with the combination treatment. Noncomparative Phase II studies have also supported efficacy in patients with metastatic breast cancer pretreated with both anthracyclines and taxanes, yielding an overall RR of 15% to 29% and median OS of 9.4 to 15.2 months. The most common dose-limiting adverse effects associated with capecitabine monotherapy are hyperbilirubinemia, diarrhea, and hand-foot syndrome. Myelosuppression, fatigue and weakness, abdominal pain, and nausea have also been reported. Compared with bolus FU/LV, capecitabine was associated with more hand-foot syndrome but less stomatitis, alopecia, neutropenia requiring medical management, diarrhea, and nausea. Capecitabine has been reported to increase serum phenytoin levels and the international normalized ratio in patients receiving concomitant phenytoin and warfarin, respectively. The dose of capecitabine approved by the US Food and Drug Administration (FDA) for both metastatic colorectal and breast cancer is 1250 Mg/M2 given orally twice per day, usually separated by 12 hours for the first 2 weeks of every 3-week cycle. CONCLUSIONS Capecitabine is currently approved by the FDA for use as first-line therapy in patients with metastatic colorectal cancer when single-agent fluoropyrimidine therapy is preferred. The drug is also approved for use as (1) a single agent in metastatic breast cancer patients who are resistant to both anthracycline- and paclitaxel-based regimens or in whom further anthracycline treatment is contra indicated and (2) in combination with docetaxel after failure of prior anthracycline-based chemotherapy. Single-agent and combination regimens have also shown benefits in patients with prostate, pancreatic, renal cell, and ovarian cancers. Improved tolerability and comparable efficacy compared with IV FU/LV in addition to oral administration make capecitabine an attractive option for the treatment of several types of cancers as well as the focus of future trials.

Abstract
With more data on the use of oxaliplatin and irinotecan available, and the recent approval of two signal transduction inhibitors for patients with advanced colorectal cancer, there are now many treatment options to choose from. From the current regimens no straightforward choice can be made that provides any patient with the optimal chance for prolonged survival with the least side-effects. The current data concerning timing and duration of chemotherapy, combination or sequential therapy, preference of agents for first-line treatment, oral fluoropyrimidines, neo-adjuvant chemotherapy for irresectable liver metastases, and the use of signal transduction inhibitors are reviewed.

Abstract
The purpose of this study was to evaluate the efficacy, assesed as response rate, and toxicity of UFT (Tegafur-Uracil) in combination with oxaliplatin as first-line treatment of advanced colorectal cancer (CRC). In all, 84 patients with recurrent or metastatic CRC with measurable disease were included. Treatment consisted of oxaliplatin 85 mg m−2 in 120-min intravenous (i.v.) infusion on days 1 and 15; i.v. l,leucovorin (l,LV) 250 mg m−2 given in 2 h on day 1, followed by oral UFT 390 mg m−2 on days 1–14, and oral l,LV 7.5 mg/12 h on days 2–14. Cycles were repeated every 28 days. A total of 492 cycles of chemotherapy were delivered with a median of six per patient (range 1–12). There was one complete response (1%) and 28 partial responses (34%) for an overall response rate of 35% (95% confidence interval (CI): 24–46%). A total of 36 patients (44%) had stable disease, whereas 17 (21%) had a progression. The median time to progression was 7.3 months and the median overall survival was 16.8 months. A prescheduled preliminary analysis was performed after inclusion of 16 patients who detected a high gastrointestinal toxicity, which led to a reduction of the UFT dose to 300 mg m−2. With this new dosage, grade 3–4 diarrhoea and grade 3–4 nausea/vomiting dropped to 21 and 14% of patients, respectively. Other grade 3–4 toxicities were stomatitis in one (1%), anaemia in three (5%), neutropenia in two (3%), thrombocytopenia in one(1%), fatigue in six (9%), peripheral sensory neuropathy in nine (14%) and laryngopharyngeal dysesthesia in two patients (2%). The combination of oxaliplatin and UFT–l,LV is an active, easy-to-administer regimen with moderate toxicity. Hence, this regimen is worthy of further investigation.

Abstract
The medical treatment of colorectal cancer (CRC) has rapidly evolved in recent years with the introduction of novel cytotoxic drugs into clinical practice such as irinotecan, oxaliplatin, and capecitabine. Combination regimens using infusional 5-fluorouracil (5-FU)/leucovorin (LV) plus either oxaliplatin or irinotecan have demonstrated clinically meaningful, high efficacy in advanced CRC. Based on the results of the Intergroup trial N9741, FOLFOX4, a combination of infusional plus bolus 5-FU/LV and oxaliplatin, has emerged as the standard first-line therapy in the palliative setting. However, infusional 5-FU-based regimens carry the need for use of central venous lines and implantable ports to allow treatment on an outpatient basis and are thus inconvenient and expensive. The use of oral fluoropyrimidines (capecitabine or uracil/tegafur [UFT] plus LV) as substitutes for infusional 5-FU in combination protocols with oxaliplatin offers greater convenience, at the same time conceivably maintaining the high efficacy and tolerability observed with intravenous protocols. Various phase I/II trials have recently been reported that investigated oxaliplatin in combination with either capecitabine or UFT/LV in patients with advanced CRC. This review will detail the results of these trials focused on capecitabine-based combinations.

Abstract
Options for first-line chemotherapy in patients with metastatic colorectal carcinoma have broadened considerably with the introduction of irinotecan and oxaliplatin. Furthermore, the oral fluoropyrimidine capecitabine has demonstrated efficacy in Phase III trials and recently was approved for first-line treatment in Europe and the United States. Capecitabine yielded similar median times to disease progression and median survival rates compared with bolus 5-fluorouracil (5-FU)/leucovorin (LV) (Mayo Clinic/North Central Cancer Treatment Group regimen), with superior and similar response rates, respectively. However, its role as a first-line, single-agent substitute for intermittent infusional 5-FU/LV remains to be defined. The addition of irinotecan or oxaliplatin to 5-FU/LV resulted in improved response rates and progression-free survival in large, randomized trials; moreover, irinotecan-containing regimens resulted in improved overall survival. Prevalent regimens of irinotecan/5-FU/LV and oxaliplatin/5-FU/LV have been compared in two randomized Phase III trials. One study demonstrated the statistical superiority of oxaliplatin/infusional 5-FU/LV over irinotecan/bolus 5-FU/LV in terms of response, time to disease progression, and median survival; however, those advantages may have been attributable to infusional administration or to major differences in second-line therapy. A randomized Phase III study comparing irinotecan and oxaliplatin in combination with the same infusional 5-FU/LV regimens and crossover in case of disease progression showed equivalent efficacy for both schedules in the first-line setting, but the irinotecan combination proved beneficial in terms of safety. New molecular targeted agents, such as angiogenesis-modulating compounds (e.g., bevacizumab) and epidermal growth factor receptor inhibitors (e.g., cetuximab), are under clinical investigation. This review updates current systemic frontline treatments and future perspectives for patients with advanced colorectal carcinoma.

Abstract
The oral fluoropyrimidine capecitabine (Xeloda) delivers 5-FU to the tumour site, thereby limiting the side effects and other complications associated with intravenous (i.v.) 5-FU. As an oral drug, capecitabine is preferred to 5-FU by many patients as it can be conveniently taken at home. In first-line metastatic colorectal cancer (MCRC), capecitabine results in superior response rates and equivalent progression-free and overall survival compared with i.v. 5-FU/LV. There is also increasing evidence for replacing i.v. 5-FU with capecitabine in combination with other anticancer agents (e.g. oxaliplatin and irinotecan) in MCRC and in the adjuvant treatment of early stage colon cancer. In anthracycline-pretreated metastatic breast cancer (MBC), adding capecitabine to docetaxel improves survival, time to progression (TTP) and response rates beyond docetaxel. Single-agent capecitabine is also effective in pretreated MBC and is a promising first-line therapy. Capecitabine has a favourable safety profile, the most frequent adverse events being hand-foot syndrome, stomatitis and diarrhoea. Because capecitabine is orally administered, it is possible to intervene promptly with dose interruption/reduction to resolve adverse events without impacting on efficacy. The increasing availability of capecitabine in the home-based setting requires careful consideration of the role of the oncology nurse, who is the key link between the patient and clinician for effective and efficient management.
