Jiang Y, Zhao M, Tang W, Zheng X. Impacts of systemic treatments on health-related quality of life for patients with metastatic colorectal cancer: a systematic review and network meta-analysis. BMC Cancer 2024; 24:188. [PMID: 38336718 PMCID: PMC10854105 DOI: 10.1186/s12885-024-11937-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2023] [Accepted: 01/30/2024] [Indexed: 02/12/2024] Open
Abstract
OBJECTIVE There is limited evidence of comparative results among different treatments regarding impacts of Health-Related Quality of Life (HRQoL) for patients with metastatic colorectal cancer (mCRC). We aimed to compare efficacy of systemic treatments on HRQoL among patients with mCRC. METHODS We collected randomized controlled trials (RCTs) reported in English up until July 2023, from databases including PubMed, Embase, Cochrane Library, ClinicalTrials.gov, and prominent conference databases, for this Bayesian network meta-analysis. Phase 2 or 3 trials that evaluated at least two therapeutic regimens were included. Primary outcomes were short-term and long-term mean changes in EORTC QLQ-C30 global health status/quality of life (GHS/QoL) scores. Secondary outcome was mean change in EQ-5D health utility scores. Mean differences (MDs) with 95% confidence intervals (CIs) were used as effect size. Subgroup analysis was performed based on whether patients received systemic treatments before. We conducted various sensitivity analyses, including differentiating between chemotherapy types, and analyzed patient cohorts with non-specified gene expression levels as well as those with target KRAS expression statuses. The current systematic review protocol was registered on PROSPERO (CRD42023453315 and CRD42023420498). RESULTS Immunotherapy and targeted therapy significantly improved HRQoL over chemotherapy, with MDs of 9.27 (95% CI: 3.96 to 14.6) and 4.04 (95% CI: 0.11 to 7.94), respectively. Monotherapy significantly outperformed both combination therapy (MD 5.71, 95%CI 0.78 to 10.63) and no active treatment (MD 3.7, 95%CI 1.41 to 6.01) regarding GHS/QoL in the short-term. Combining targeted therapy with chemotherapy did not improve HRQoL. Focusing on HRQoL, cetuximab excelled when gene expression baselines were unspecified. Subgroup and sensitivity analyses upheld these robust findings, unaffected by model or patient baseline characteristics. Evidence from clinical trials without specific gene level data suggested that monotherapies, especially targeted therapies such as cetuximab, demonstrated superiority in HRQoL. For KRAS wild-type patients, no significant HRQoL differences emerged between chemotherapy, targeted therapy, or their combination.. CONCLUSIONS Targeted therapies and immunotherapy demonstrate superior HRQoL benefits, monotherapy such as cetuximab is associated with significant improvements as compared to combination therapy. However, tailoring these results to individual gene expression profiles requires more evidence.

Increasing Dosage of Leucovorin Results in Pharmacokinetic and Gene Expression Differences When Administered as Two-Hour Infusion or Bolus Injection to Patients with Colon Cancer. Cancers (Basel) 2022; 15:cancers15010258. [PMID: 36612253 PMCID: PMC9818718 DOI: 10.3390/cancers15010258] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2022] [Revised: 12/26/2022] [Accepted: 12/28/2022] [Indexed: 01/03/2023] Open
Abstract
The combination of 5-fluorouracil (5-FU) and leucovorin (LV) forms the chemotherapy backbone for patients with colorectal cancer. However, the LV administration is often standardized and not based on robust scientific data. To address these issues, a randomized pharmacokinetics study was performed in patients with colon cancer. Thirty patients were enrolled, receiving 60, 200 or 500 mg/m2 LV as a single two-hour infusion. Blood, tumor, mucosa, and resection margin biopsies were collected. Folate concentrations were analyzed with LC-MS/MS and gene expression with qPCR. Data from a previous study where patients received LV as bolus injections were used as comparison. Saturation of methylenetetrahydrofolate (MeTHF) and tetrahydrofolate (THF) levels was seen after two-hour infusion and polyglutamated MeTHF + THF levels in tumors decreased with increasing LV dosage. The decrease was associated with decreased FPGS and increased GGH expression, which was not observed after LV bolus injection. In the bolus group, results indicate activation of a metabolic switch possibly promoting TYMS inhibition in response to 5-FU. Different metabolic mechanisms appear to be induced when LV is administered as infusion and bolus injection. Since maximal inhibition of TYMS by the 5-FU metabolite 5-fluoro-2'-deoxyuridine 5'-monophosphate (FdUMP) requires excess polyglutamated MeTHF, the results point in favor of the bolus regimen.

Abstract
Simple Summary Discovery of anticancer targets with minimal side effects is a major challenge in drug discovery and development. This study developed a fuzzy optimization framework for identifying anticancer targets. The framework was applied to identify not only gene regulator targets but also metabolite- and reaction-centric targets. The computational results show that the combination of a carbon metabolism target and any one-target gene that participates in the sphingolipid, glycerophospholipid, nucleotide, cholesterol biosynthesis, or pentose phosphate pathways is more effective for treatment than one-target inhibition is, and a two-target combination of 5-FU and folate supplement can improve cell viability, reduce metabolic deviation, and reduce side effects of normal cells. Abstract The efficient discovery of anticancer targets with minimal side effects is a major challenge in drug discovery and development. Early prediction of side effects is key for reducing development costs, increasing drug efficacy, and increasing drug safety. This study developed a fuzzy optimization framework for Identifying AntiCancer Targets (IACT) using constraint-based models. Four objectives were established to evaluate the mortality of treated cancer cells and to minimize side effects causing toxicity-induced tumorigenesis on normal cells and smaller metabolic perturbations. Fuzzy set theory was applied to evaluate potential side effects and investigate the magnitude of metabolic deviations in perturbed cells compared with their normal counterparts. The framework was applied to identify not only gene regulator targets but also metabolite- and reaction-centric targets. A nested hybrid differential evolution algorithm with a hierarchical fitness function was applied to solve multilevel IACT problems. The results show that the combination of a carbon metabolism target and any one-target gene that participates in the sphingolipid, glycerophospholipid, nucleotide, cholesterol biosynthesis, or pentose phosphate pathways is more effective for treatment than one-target inhibition is. A clinical antimetabolite drug 5-fluorouracil (5-FU) has been used to inhibit synthesis of deoxythymidine-5′-triphosphate for treatment of colorectal cancer. The computational results reveal that a two-target combination of 5-FU and a folate supplement can improve cell viability, reduce metabolic deviation, and reduce side effects of normal cells.

Abstract
PURPOSE The utility of administering fluorouracil (5-FU) in bolus in regimens of infusional 5-FU has been questioned. We aimed to quantify the use of 5-FU bolus in infusional regimens for gastrointestinal malignancies among Brazilian oncologists. METHODS This was a cross-sectional electronic survey composed of eight multiple-choice questions sent to Brazilian oncologists during 14 days in February 2021. The survey instrument collected demographic data of participants and assessed practices in terms of 5-FU bolus use. We evaluated the association of demographic variables and 5-FU prescribing patterns with Fisher’s exact test (odds ratio [OR]). RESULTS The survey was completed by 332 medical oncologists. Overall, 37% were experienced oncologists and 32% were gastrointestinal specialists. In the first-line metastatic and in the adjuvant settings, 40% and 67% of oncologists always prescribe 5-FU bolus in infusional regimens, respectively. Experienced oncologists more frequently omit 5-FU bolus when compared with early-career oncologists, both in the metastatic (41% v 26%; OR, 1.98; P = .005) and adjuvant settings (28% v 14%; OR, 2.32; P = .003). In addition, more GI specialists remove 5-FU bolus when compared with generalists, but only in the metastatic setting (44% v 25%; OR, 2.33; P = .001). GI specialists are more likely to consider that treatment efficacy is not affected by 5-FU bolus withdrawal than are generalists (89% v 75%; OR, 2.65; P = .003). Most respondents (67%) keep leucovorin at the same doses when omitting 5-FU bolus, and only 16% always recommend dihydropyrimidine dehydrogenase testing. CONCLUSION Our survey indicates that experience in oncology practice and percentage of time dedicated to treat GI cancers influence the prescription of 5-FU bolus in Brazil, with more frequent omission of it among experienced gastrointestinal specialists, particularly in the metastatic setting.

Abstract
AIM The European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) assesses the health-related quality of life of patients in cancer trials. There are currently no minimally important difference (MID) guidelines for the EORTC QLQ-C30 for colorectal cancer (CRC). This study aims to estimate MIDs for the EORTC QLQ-C30 scales in patients with advanced CRC treated with chemotherapy and enrolled in clinical trials. METHOD The data were obtained from three published EORTC trials that treated CRC patients using chemotherapy. Potential anchors were selected from clinical variables based on their correlation with EORTC QLQ-C30 scales. Anchor-based MIDs for within-group change and between-group change were estimated via the mean change method and linear regression, respectively, and summarized using weighted correlation. Distribution-based MIDs were also examined. RESULTS Anchor-based MIDs were determined for deterioration in 8 of the 14 EORTC QLQ-C30 scales and in 9 scales for improvement, and varied by scale, direction of change and anchor. MIDs for improvement (deterioration) ranged from 6 to 18 (-11 to -5) points for within-group change and 5 to 15 (-10 to -4) for between-group change. Summarized MIDs (in absolute values) per scale mostly ranged from 5 to 10 points. CONCLUSIONS These findings have clinical relevance for the interpretation of treatment efficacy and the design of clinical trials by informing sample size requirements.

Abstract
Colorectal cancer (CRC) is the third most common malignancy in the world and the second cause of cancer-related deaths. Despite the search for new therapeutic agents, there are still many doubts concerning the quality of life (QOL) improvement in palliative patients. In this study, we assessed the impact of oncology knowledge on QOL and the relationship between QOL and various environmental factors and unconventional treatment methods in patients with CRC treated with chemotherapy and targeted therapy. The results of first-line palliative chemotherapy in 330 patients with colorectal cancer treated between January 2010 and December 2016 in two centers were analyzed. The average age of patients was 66 ± 11.7 years. Median survival time was 25 months. In multivariate analysis, the performance status and response to treatment had a significant effect on survival time. A trend towards shorter survival was also observed in patients receiving 5-FU monotherapy, in elderly patients and in patients with less oncology knowledge. A relationship between general quality of life and performance status (PS 0 vs. PS > 0), response to treatment and oncology knowledge was found. Patients with limited oncology knowledge more often used unconventional therapy methods in parallel with the treatment. In patients over 70 years of age and in patients with worse overall condition, 5-FU monotherapy was more commonly used (p < 0.01). The level of oncology knowledge of the treated patients observed in everyday clinical practice may be related to some parameters of treatment effectiveness assessment, such as QOL and may be related to the use of unconventional treatment methods. Those, in turn may have an impact on the QOL of the treated patients.

Abstract
Cardiovascular diseases (CVD) and cancer are still the leading causes of death. There are many common etiologic factors, especially smoking and obesity. Therefore, it is not uncommon for CVD and cancer to coexist. Drug-drug interactions (DDIs) inevitably occur in this group of patients, where polypharmacy is increasing due to older age and multiple comorbidities. However, multidisciplinary studies, especially close collaboration of medical oncologists and cardiologists, who deals with the diagnosis and treatment of these diseases, awareness and preventive approaches to DDIs may reduce serious morbidity and mortality. In this review, information about the common treatments used in cardiology and oncology and possible DDIs are discussed.

Abstract
PURPOSE The aim of our study was to compare the characteristics and prognosis between right- and left-sided metastatic colorectal carcinomas. METHODS Data from 937 patients with stage IV colorectal carcinomas (synchronous distant metastasis) who had a resection of the primary tumour between 1985 and 2014 were analysed. Carcinomas in the caecum to transverse colon were defined as right-sided (n = 250; 26.7%). They were compared to tumours located from the splenic flexure to the rectum categorised as left-sided (n = 687; 73.3%). RESULTS In right-sided carcinomas, we observed significantly more female patients (50.8 vs 36.2%; p < 0.001), more unfavourable histological types (24.0 vs 8.6%; p < 0.001), more M1c carcinomas (metastases to the peritoneum ± others; 32.0 vs 14.4%; p < 0.001) and more emergencies (11.6 vs 7.1%; p = 0.029), while multimodal treatment was utilised in fewer patients (51.6 vs 63.8%; p = 0.001) and curative resections were less frequently (24.1 vs 35.4%; p = 0.002). Prognosis was significantly worse in patients with right-sided carcinomas (2-year-survival 27.2 vs 44.6%, p < 0.01). This difference was more pronounced after R2 resection (15.3 vs 29.7%; p < 0.001), than after macroscopic curative resection (2-year-survival 63.9 vs 71.9%; p = 0.106). In multivariate Cox regression analysis, tumour site was found to be an independent prognostic factor for overall survival (HR 1.2; 95% CI 1.0-1.5; p = 0.012). During the three 10-year periods, the prognosis improved equally in patients with right- and left-sided carcinomas, while the differences in survival remained identical. CONCLUSIONS In a surgical patient cohort undergoing primary tumour resection, significant differences in prognosis were observed between patients with metastatic right- and left-sided colorectal carcinomas.

Abstract
Traditionally, the efficacy of cancer treatment in patients with advance or metastatic disease in clinical studies has been studied using overall survival and more recently tumor-based end points such as progression-free survival, measurements of response to treatment. However, these seem not to be the relevant clinical end points in current situation if such end points were no validated as surrogate of overall survival to demonstrate the clinical efficacy. Appropriate, meaningful, primary patient-oriented and patient-reported end points that adequately measure the effects of new therapeutic interventions are then crucial for the advancement of clinical research in metastatic colorectal cancer to complement the results of tumor-based end points. Health-related quality of life (HRQoL) is effectively an evaluation of quality of life and its relationship with health over time. HRQoL includes the patient report at least of the way a disease or its treatment affects its physical, emotional and social well-being. Over the past few years, several phase III trials in a variety of solid cancers have assessed the incremental value of HRQoL in addition to the traditional end points of tumor response and survival results. HRQoL could provide not only complementary clinical data to the primary outcomes, but also more precise predictive and prognostic value. This end point is useful for both clinicians and patients in order to achieve the dogma of precision medicine. The present article examines the use of HRQoL in phase III metastatic colorectal cancer clinical trials, outlines the importance of HRQoL assessment methods, analysis, and results presentation. Moreover, it discusses the relevance of including HRQoL as a primary/co-primary end point to support the progression-free survival results and to assess efficacy of treatment in the advanced disease setting.

[PMID: 27871319 PMCID: PMC5117585 DOI: 10.1186/s12885-016-2933-6] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2016] [Accepted: 10/28/2016] [Indexed: 12/27/2022] Open
Abstract
Background PEP02 (also known as MM-398, nal-IRI) is a novel nanoparticle formulation of irinotecan encapsulated in liposomes. The aims of this study were to investigate the dose-limiting toxicity (DLT), maximum tolerated dose (MTD) and pharmacokinetics (PK) of PEP02 in combination with 5-FU and LV, in patients with advanced refractory solid tumors. Methods Patients were enrolled in cohorts to receive PEP02 from 60 to 120 mg/m2 (dose expressed as the irinotecan hydrochloride trihydrate salt) as a 90-min intravenous infusion on day 1, followed by 24 h infusion of 5-FU 2,000 mg/m2 and LV 200 mg/m2 on days 1 and 8, every 3 weeks. Results A total of 16 patients were assigned to four dose levels, 60 (three patients), 80 (six patients), 100 (five patients) and 120 mg/m2 (two patients). DLT was observed in four patients, two at the 100 mg/m2 dose level (one had grade III infection with hypotension and grade III hemorrhage; the other had grade III diarrhea and grade IV neutropenia), and two at the 120 mg/m2 dose level (one had grade III diarrhea and grade IV neutropenia; the other had grade III diarrhea). The MTD of PEP02 was determined as 80 mg/m2. The most common treatment-related adverse events were nausea (81%), diarrhea (75%) and vomiting (69%). Among the six patients who received the MTD, one patient exhibited partial response, four patients had stable disease and one showed progressive disease. Pharmacokinetic data showed that PEP02 had a lower peak plasma concentration, longer half-life, and increased area under the plasma concentration-time curve from zero to time t of SN-38 than irinotecan at similar dose level. Conclusions The MTD of PEP02 on day 1 in combination with 24-h infusion of 5-FU and LV on days 1 and 8, every 3 weeks was 80 mg/m2, which will be the recommended dose for future studies. Trial registration The trial was retrospectively registered (NCT02884128) with date of registration: August 12, 2016.

Abstract
Purpose The CONSORT extension for patient reported outcomes (PROs) aims to improve reporting, but guidance on the optimal integration with clinical data is lacking. This study examines in detail the reporting of PROs and clinical data from randomized controlled trials (RCTs) in gastro-intestinal cancer to inform design and reporting of combined PRO and clinical data from trials to improve the ‘take home’ message for clinicians to use in practice. Materials and Methods The case study was undertaken in gastro-intestinal cancer trials. Well-conducted RCTs reporting PROs with validated instruments were identified and categorized into those combining PRO and clinical data in a single paper, or those separating data into linked primary and supplemental papers. Qualitative methods were developed to examine reporting of the critical interpretation of the trial results (trial exegesis) in the papers in relation of the PRO and clinical outcomes and applied to each publication category. Results were used to inform recommendations for practice. Results From 1917 screened abstracts, 49 high quality RCTs were identified reported in 36 combined and 15 linked primary and supplemental papers. In-depth analysis of manuscript text identified three categories for understanding trial exegesis: where authors reported a “detailed”, “general”, or absent PRO rationale and integrated interpretation of clinical and PRO results. A total of 11 (30%) and 6 (16%) combined papers reported “detailed” PRO rationale and integrated interpretation of results although only 2 (14%) and 1 (7%) primary papers achieved the same standard respectively. Supplemental papers provide better information with 11 (73%) and 3 (20%) achieving “detailed” rationale and integrated interpretation of results. Supplemental papers, however, were published a median of 20 months after the primary RCT data in lower impact factor journals (median 16.8 versus 5.2). Conclusion It is recommended that single papers, with detailed PRO rationale and integrated PRO and clinical data are published to optimize trial exegesis. Further work to examine whether this improves the use of PRO data to inform practice is needed.

Abstract
Background Pharmacokinetic guided dosing of 5-fluorouracil chemotherapies to bring plasma 5-fluorouracil into a desired therapeutic range may lead to fewer side effects and better patient outcomes. High performance liquid chromatography and a high throughput nanoparticle immunoassay (My5-FU) have been used in conjunction with treatment algorithms to guide dosing. The objective of this study was to assess accuracy, clinical effectiveness and safety of plasma 5-fluorouracil guided dose regimen(s) versus standard regimens based on body surface area in colorectal cancer. Methods We undertook a systematic review. MEDLINE; MEDLINE In-Process & Other Non-Indexed Citations; EMBASE; Cochrane Library; Science Citation Index and Conference Proceedings (Web of Science); and NIHR Health Technology Assessment Programme were searched from inception to January 2014. We reviewed evidence on accuracy of My5-FU for estimating plasma 5-fluorouracil and on the clinical effectiveness of pharmacokinetic dosing compared to body surface area dosing. Estimates of individual patient data for overall survival and progression-free survival were reconstructed from published studies. Survival and adverse events data were synthesised and examined for consistency across studies. Results My5-FU assays were found to be consistent with reference liquid chromatography tandem mass spectrometry. Comparative studies pointed to gains in overall survival and in progression-free survival with pharmacokinetic dosing, and were consistent across multiple studies. Conclusions Although our analyses are encouraging, uncertainties remain because evidence is mainly from outmoded 5-fluorouracil regimens; a randomised controlled trial is urgently needed to investigate new dose adjustment methods in modern treatment regimens.

Abstract
BACKGROUND 5-Fluorouracil (5-FU) is a chemotherapy used in colorectal, head and neck (H&N) and other cancers. Dose adjustment is based on body surface area (BSA) but wide variations occur. Pharmacokinetic (PK) dosing is suggested to bring plasma levels into the therapeutic range to promote fewer side effects and better patient outcomes. We investigated the clinical effectiveness and cost-effectiveness of the My5-FU assay for PK dose adjustment to 5-FU therapy. OBJECTIVES To systematically review the evidence on the accuracy of the My5-FU assay compared with gold standard methods [high-performance liquid chromatography (HPLC) and liquid chromatography-mass spectrometry (LC-MS)]; the effectiveness of My5-FU PK dosing compared with BSA; the effectiveness of HPLC and/or LC-MS compared with BSA; the generalisability of published My5-FU and PK studies; costs of using My5-FU; to develop a cost-effectiveness model. DATA SOURCES We searched MEDLINE, EMBASE, Science Citation Index and other databases between January and April 2014. METHODS Two reviewers independently screened titles and abstracts with arbitration and consensus agreement. We undertook quality assessment. We reconstructed Kaplan-Meier plots for progression-free survival (PFS) and overall survival (OS) for comparison of BSA and PK dosing. We developed a Markov model to compare My5-FU with BSA dosing which modelled PFS, OS and adverse events, using a 2-week cycle over a 20 year time horizon with a 3.5% discount rate. Health impacts were evaluated from the patient perspective, while costs were evaluated from the NHS and Personal Social Services perspective. RESULTS A total of 8341 records were identified through electronic searches and 35 and 54 studies were included in the clinical effectiveness and cost-effectiveness reviews respectively. There was a high apparent correlation between My5-FU, HPLC and LC-MS/mass spectrometer but upper and lower limits of agreement were -18% to 30%. Median OS were estimated as 19.6 [95% confidence interval (CI) 17.0 to 21.0] months for PK versus 14.6 (95% CI 14.1 to 15.3) months for BSA for 5-FU+folinic acid (FA); and 27.4 (95% CI 23.2 to 38.8) months for PK versus 20.6 (95% CI 18.4 to 22.9) months for BSA for FOLFOX6 in metastatic colorectal cancer (mCRC). PK versus BSA studies were generalisable to the relevant populations. We developed cost-effectiveness models for mCRC and H&N cancer. The base case assumed a cost per My5-FU assay of £ 61.03. For mCRC for 12 cycles of a oxaliplatin in combination with 5-fluorouracil and FA (FOLFOX) regimen, there was a quality-adjusted life-year (QALY) gain of 0.599 with an incremental cost-effectiveness ratio of £ 4148 per QALY. Probabilistic and scenario analyses gave similar results. The cost-effectiveness acceptability curve showed My5-FU to be 100% cost-effective at a threshold of £ 20,000 per QALY. For H&N cancer, again, given caveats about the poor evidence base, we also estimated that My5-FU is likely to be cost-effective at a threshold of £ 20,000 per QALY. LIMITATIONS Quality and quantity of evidence were very weak for PK versus BSA dosing for all cancers with no randomised controlled trials (RCTs) using current regimens. For H&N cancer, two studies of regimens no longer in use were identified. CONCLUSIONS Using a linked evidence approach, My5-FU appears to be cost-effective at a willingness to pay of £ 20,000 per QALY for both mCRC and H&N cancer. Considerable uncertainties remain about evidence quality and practical implementation. RCTs are needed of PK versus BSA dosing in relevant cancers.

Abstract
TAS-102 is a new oral anti-tumor drug, composed of a thymidine-based nucleoside analog (trifluridine: FTD) and a thymidine phosphorylase inhibitor (tipiracil hydrochloride: TPI). TAS-102 has been shown to significantly improve overall survival and progression-free survival in patients with refractory metastatic colorectal cancer (mCRC) in placebo-controlled randomized phase II and III trials. The current review summarizes mechanisms of action, pharmacokinetics/dynamics and preclinical and clinical data of TAS-102 in colorectal cancer. TAS-102 is a new salvage-line treatment option for patients with mCRC. TAS-102 is well tolerated and has great potential in future clinical drug combination therapies.

Abstract
PURPOSE In high risk gastric and gastroesophageal adenocarcinoma, adjuvant radiochemotherapy with 5-fluorouracil bolus became a standard adjuvant treatment, showing significant improvement in overall survival after surgery, although with substantial toxicity. We explored the efficacy and toxicity of a modified 5-fluorouracil continuous infusion scheme. METHODS We conducted an observational retrospective study in our centre. Gastric/gastroesophageal junction adenocarcinoma patients were treated with a schedule consisting in four infusions of bolus 5-fluorouracil 400 mg/m(2) iv with leucovorin 200 mg/m(2) iv and 1200 mg/m(2) in 46-hour infusion of 5-fluorouracil (D'Gramont scheme), followed by concomitant radiochemotherapy (45 Gy in 25 fractions of 1.8 Gy) with 5-fluorouracil continuously infusion 225 mg/m(2)/day and four additional infusions of chemotherapy one month after complete radiochemotherapy. RESULTS Between January 2007 and December 2013, 55 patients received a mean of 3.16 bi-weekly adjuvant infusions followed by 4.6 weeks of continuous treatment concurrent with radiotherapy and 3.72 bi-weekly infusions after radiotherapy treatment. During adjuvant treatment, grade III toxicity was mostly haematologic, while gastrointestinal and cutaneous toxicity was predominant during concurrent treatment. There were no grade IV- or treatment-related deaths during this study. Disease-free survival (DFS) was 79.2 months (56.3-102.1 months), and the 3-year survival rates were 52.7 %. CONCLUSIONS This 5-fluorouracil infusional scheme has an excellent tolerability profile and favourable efficacy results.

Abstract
OBJECTIVE To investigate the effects of E7080 and N (5)-(1-iminoethyl)-L-ornithine dihydrochloride (L-NIO) on colorectal cancer alone and in combination. METHODS HT29 colorectal cancer cell line from Sap Institute was used. Real-time cell analysis (xCELLigence system) was performed to determine the effects of E7080 and L-NIO on colorectal cell proliferation. While apoptosis was determined with Annexin V staining, and the effect of agents on angiogenesis was determined with chorioallantoic membrane (CAM) model. RESULTS We found that E7080 has a strong antiproliferative effect with an half maximum inhibition of concentration (IC50) value of 5.60×10(-8) mol/L. Also it has been observed that E7080 showed antiangiogenic and apoptotic effects on HT29 colorectal cancer cells. Antiangiogenic scores of E7080 were 1.2, 1.0 and 0.6 for 100, 10 and 1 nmol/L E7080 concentrations, respectively. Furthermore, apoptosis has been detected in 71% of HT29 colorectal cancer cells after administration of 100 nmol/L E7080 which may indicate strong apoptotic effect. Meanwhile administration of L-NIO alone did not show any effect, but the combination of E7080 with L-NIO increased the antiproliferative, antiangiogenic and apoptotic effects of E7080. CONCLUSIONS Results of this study indicate that E7080 may be a good choice in treatment of colorectal tumors. Furthermore the increased effects of E7080 when combined with L-NIO raise the possibility to use a lower dose of E7080 and therefore avoid/minimize the side effects observed with E7080.

Abstract
This manuscript summarizes recent progress in the adjuvant treatment of colon cancer. 5-Fluorouracil plus leucovorin, that have been considered standard therapy over the last 15 years, have now been replaced by combination chemotherapy, at least in stage III disease. The treatment of stage II disease is still somewhat less established. Prognostic and predictive biological markers are urgently needed for further fine-tuning of therapy. Molecular targeted agents have been developed with proven activity in advanced disease and are now being assessed in the adjuvant setting. It is expected that the inclusion of these new agents will lead to a further enhancement of treatment outcome. Those involved in the treatment of colorectal cancer should be encouraged to continue to provide optimal patient care and to participate in clinical trials in order to increase the evidence on which they can base their clinical judgement and to make further progress.

Abstract
PURPOSE To investigate whether infusional high-dose 5-flurouracil (HD-FU) provides a significant improvement in recurrence-free survival (RFS) and overall survival (OS) compared with a standard bolus 5-FU regimen (Mayo Clinic) in patients with curatively resectable stage III colon cancer. METHODS Patients (n=1601) were randomised to receive either the Mayo Clinic regimen or one of the three HD-FU regimens; LV5FU2, the Arbeitsgemeinschaft Internistische Onkologie (AIO) or the Grupo Espaňol para el Tratamiento Digestivos (TTD), the data from which were combined to provide the HD-FU arm for final analysis. RESULTS Patients were evenly balanced for age, TMN, tumor grade and vascular and lymphatic invasion. Median follow-up was approximately 42months, RFS (hazard ratio [HR]=0.997) and OS (HR=0.96) (primary end-point) were not statistically different between the two treatment arms. Infusional HD-FU was generally better tolerated than bolus 5-FU regimen. CONCLUSIONS Infusional HD-FU does not improve RFS and OS in curatively resected stage III colon cancer patients compared to the Mayo Clinic regimen, but is less toxic.

Abstract
Pooled analyses of chemotherapy trials in metastatic colorectal cancer (mCRC) have suggested that progression-free survival (PFS) is a surrogate endpoint for overall survival (OS). However, this has not been evaluated under current standard-of-care regimens of chemotherapy in combination with targeted therapies. We conducted an analysis of published mCRC trials of chemotherapy and targeted therapies from 2000 to evaluate the surrogacy of PFS and response rate (RR) for OS. Study-level data was pooled from 24 randomized mCRC trials that evaluated fluoropyrimidine-based regimens and included trials conducted with targeted agents (panitumumab, cetuximab, bevacizumab, and aflibercept). A total of 69 treatment arms with a sample size of 20,438 patients was included. Linear regression analysis was carried out to estimate the correlation of PFS and RR with OS. The correlation coefficient between PFS HRs and OS HRs was 0.86 for all trials, 0.89 for 12 phase III trials of targeted agents in combination with chemotherapy, 0.95 for 8 first-line phase III trials of targeted agents, and 0.83 for 9 trials of anti-EGFR-targeted agents. In all cases, correlation coefficients between RR and OS HRs were lower than those between PFS HRs and OS HRs (range, 0.42-0.81). In this study-level analysis of randomized mCRC trials of chemotherapy and targeted agents, improvements in PFS are strongly correlated with improvements in OS. This suggests that PFS remains a valid surrogate endpoint for OS with current treatment regimens in the mCRC setting.

Abstract
PURPOSE To evaluate progression-free survival (PFS) as a potential surrogate endpoint (SEP) for overall survival (OS) in metastatic colorectal cancer (mCRC) with a focus on applicability to trials containing targeted therapy with anti-VEGF- or anti-EGF receptor (EGFR)-directed monoclonal antibodies. EXPERIMENTAL DESIGN A systematic literature search of randomized trials of first-line chemotherapy for mCRC reported from January 2000 to January 2012 was conducted. Adjusted weighted linear regression was used to calculate correlations within PFS and OS (endpoints; R(EP)) and between treatment effects on PFS and on OS (treatment effects; R(TE)). RESULTS Fifty trials reflecting 22,736 patients met the inclusion criteria. Correlation between treatment effects on PFS and OS and between the endpoints PFS and OS was high across all studies (R(TE) = 0.87, R(EP) = 0.86). This was also observed in chemotherapy-only trials (R(TE) = 0.93, R(EP) = 0.81) but less so for trials containing monoclonal antibodies (R(TE) = 0.47; R(EP) = 0.52). Limiting the analysis to bevacizumab-based studies (11 trials, 3,310 patients) again yielded high correlations between treatment effects on PFS and on OS (R(TE) = 0.84), whereas correlation within PFS and OS was low (R(EP) = 0.45). In 7 trials (1,335 patients) investigating cetuximab- or panitumumab-based studies, contrasting correlations with very wide confidence intervals were observed (R(TE) = 0.28; R(EP) = 0.96). CONCLUSIONS PFS showed consistently high correlation with OS of an order that would justify its use as an SEP in chemotherapy regimens. For validation of surrogacy in anti-VEGF and anti-EGFR-directed therapies, further research and a larger set of trials is needed.

Abstract
BACKGROUND We examined if cancer patients' health-related quality of life (HRQoL) scores on the European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C30 are affected by the specific time point, before or during treatment, at which the questionnaire is completed, and whether this could bias the overall treatment comparison analyses. PATIENTS AND METHODS A 'completion-time window' variable was created on three closed EORTC randomised control trials in lung (non-small cell lung cancer, NSCLC) and colorectal cancer (CRC) to indicate when the QLQ-30 was completed relative to chemotherapy cycle dates, defined as 'before', 'on' and 'after'. HRQoL mean scores were calculated using a linear mixed model. RESULTS Statistically significant differences (P<0.05) were observed on 6 and 5 scales for 'on' and 'after' comparisons in the NSCLC and two-group CRC trial, respectively. As for the three-group CRC trial, several statistical differences were observed in the 'before' to 'on' and the 'on' to 'after' comparisons. For all three trials, including the 'completion-time window' variable in the model resulted in a better fit, but no substantial changes in the treatment effects were noted. CONCLUSIONS We showed that considering the exact timing of completion within specified windows resulted in statistical and potentially clinically significant differences, but it did not alter the conclusions of treatment comparison in these studies.

Abstract
BACKGROUND Best response rates have been achieved with three-drug regimens containing 5-FU in the treatment of advanced gastric cancer (AGC) and oral fluoropyrimidines are the best alternatives as substitutes for infusional 5-FU. This study aimed to evaluate the safety and toxicity of epirubicin, cisplatin, and UFT (ECU regimen) regimens in AGC outpatients. MATERIALS AND METHODS Forty-one patients with AGC received epirubicin, cisplatin, and oral UFT plus leucovorin. Epirubicin 50 mg/m(2) and cisplatin 60mg/m(2) were administered on Day 1. Three hundreds (300) mg/m(2)/day UFT was administered with leucovorin at a fixed oral dose of 90 mg/day for 21 days, followed by a 7-day rest period. Cycles were repeated every 4 weeks. Performance status was either as 0 and 1. RESULTS Among the 41 patients enrolled, complete and partial response was achieved in 7.3% and 36.6% of patients, respectively, with an overall response rate of 43.9%. Stable disease was observed in 34.1% of patients and 22% showed disease progression. Median time to progression was 5.2 months and median survival was 12.3 months. A median of 4 cycles (range: 1-6) of chemotherapy were administered. The main grade III-IV toxicities were nausea/vomiting (19.4%) and neutropenia (12.1%). Grade IV toxicities were gastric perforation and renal failure. CONCLUSION ECU appears to be an effective regimen in the treatment of AGC, with acceptable tolerability and manageable toxicity. In three-drug regimens, substitution of infusional 5-FU by UFT offers the possibility of increased AGC outpatient compliance.

Abstract
A major problem concerning the addition of more drugs in a chemotherapy combination is designing a proper schedule assuring the balance between dose intensity of each drug, efficacy of the combination, and tolerability lessening the burden of drug toxicity. We evaluated triplet chemotherapy-based intensive regimens proposed as first-line treatment in patients with metastatic colorectal cancer. Using a FOLFOXIRI (5-fluorouracil [5-FU], irinotecan, and oxaliplatin) combination regimen, patients with metastatic colorectal cancer now have the possibility of longer survival, but disappointingly, with increased toxicities. Triplet chemotherapy regimen according to 5-fluorouracil, irinotecan /5-fluorouracil, oxaliplatin, characterized by timed flat-infusion 5-FU administration, without leucovorin, obtained efficacy equivalent to other reported similar combination regimens (5-FU, irinotecan, and oxaliplatin), with increased received 5-FU dose intensity and lower grade 3 to 4 neutropenia. To guarantee the proper balance between dose intensities, efficacy, and toxicity, triplet chemotherapy schedules could be further improved by abrogation of folinic acid and bolus 5-FU, a new and easy modality of 5-FU administration, such as timed flat-infusion 5-FU, associated with alternating irinotecan and oxaliplatin; this could favor diffusion of this intensive treatment in clinical practice.

Abstract
AIM The simultaneous administration of irinotecan, 5-fluorouracil, folinic acid and oxaliplatin (FOLFOXIRI) has been compared with standard 5-fluorouracil, folinic acid and irinotecan (FOLFIRI) in randomized trials in metastatic colorectal cancer patients. A superior efficacy of FOLFOXIRI has been reported by some authors, but others have failed to show any differences and do not recommend its use because of greater cost and toxicity. We performed a systematic review of the literature to analyse efficacy and toxicity of FOLFOXIRI. METHOD Odds ratios (OR) with 95% confidence intervals (CI) were used to analyse dichotomous variables. Hazard ratios (HR) for progression and death were combined with an inverse variance method based on logarithmic conversion. A fixed-effect model and Mantel-Haenszel's method were used. Heterogeneity was tested with Cochrane's Q test and I(2) test. RESULTS A significant increase in response rate (OR 2.04; P < 0.01) was associated with treatment by FOLFOXIRI and a benefit was also shown by the HR for progression (HR 0.72; P < 0.01) and death (HR 0.71; P < 0.01). Analysis for toxicity found a significant increase associated with FOLFOXIRI except for anaemia, fatigue and febrile neutropenia. CONCLUSION FOLFOXIRI confers significant benefit in progression-free survival, survival, response and R0 resection rates but is more toxic compared with FOLFIRI.

Abstract
Colon cancer (CC) therapies have improved patient outcomes significantly over the last decades in both the adjuvant and metastatic settings. With the introduction of a number of novel agents, both traditional chemotherapies and biologically targeted agents, the need to identify subgroups that are likely and not likely to respond to a particular treatment regimen is paramount. This will allow patients who are likely to benefit to receive optimal care, while sparing those unlikely to benefit from unnecessary toxicity and cost. With the identification of several novel biomarkers and a variety of technologies to interrogate the genome, we already are able to rapidly study patient tumor or blood samples and normal tissues to generate a large dataset of aberrations within the cancer. How to digest this complex information to obtain accurate, reliable, and meaningful results that will allow us to provide truly personalized care for CC patients is just starting to be addressed. In this article, we briefly review the history of CC treatment, with an emphasis on current clinical standards that incorporate a "personalized medicine" approach. We then review strategies that will potentially improve our ability to individualize therapy in the future.

Abstract
XELOX is a 3-weekly chemotherapy combination of oral capecitabine and intravenous oxaliplatin. The central hypothesis that led to its development was that it would provide a convenient and cost-effective alternative to intravenous fluorouracil-based chemotherapy doublets, without compromising on anti-tumor efficacy. Recently its role in colorectal cancer has become more established in both the metastatic and adjuvant setting. Ongoing investigation of XELOX continues in a number of directions: its combination with novel biological agents, its efficacy and safety in the elderly, and the development of biomarkers that can predict its anti-tumor effect. This article provides a comprehensive and up-to-date synopsis of all pertinent clinical studies detailing this regimen and its promise for the future.

Abstract
OBJECTIVES The irinotecan (CPT-11) + 5-fluorouracil (5-FU)/leucovorin (LV) + UFT/LV chemotherapy, in which repetitive oral administration of UFT/LV replaces the infusion of 5-FU/LV in the FOLFIRI regimen, has been proposed previously. In this study, five of 10 patients were injected with a bolus of 5-FU and the other were not injected with it in order to examine the effect of omitting it in terms of pharmacokinetics of 5-FU. METHODS The treatment consisted of the intravenous infusions of CPT-11 at 100 mg/m(2 )and l-LV at 15 mg/m(2), and the injection of a bolus of 5-FU at 500 mg/m(2) on day 1, and the repetitive oral administration of UFT/LV (300 mg/m(2)/day as tegafur + 75 mg/day of LV) on days 1-5. A total of 13 measurements of the plasma concentrations of uracil, 5-FU and tegafur were made per patient within 48 hr after the start of chemotherapy and the value of area under the concentration-time curve (AUC(0-48)) was evaluated. The plasma concentration was also determined at 2 weeks to assess long-term exposure to 5-FU. RESULTS The plasma concentrations of 5-FU at 24 hr after the start of treatment were 27.4 ng/mL and 9.4 ng/mL in the patients with and without the bolus injection, respectively. At 48 hr, they were 31.3 ng/mL and 10.4 ng/mL with the AUC(0-48) values of 22.16 mg h/L and 0.65 mg h/L, respectively. The 5-FU was detected in the plasma at 226 hr after the last administration of UFT/LV for the patients with the bolus injection, but not for those without. CONCLUSION A bolus of 5-FU on day 1 provided long-term exposure to 5-FU.

Abstract
Metastatic colorectal cancer traditionally has been considered incurable. Over the past 3 decades, however, resection of low-volume hepatic disease has been recognized as beneficial in some cases. More recently, resection of isolated pulmonary metastases has been shown to offer long-term survival in carefully selected patients. Resection of metastases to more unusual sites (ovary, brain, peritoneal cavity) is more controversial; nevertheless, retrospective data suggest that a few patients may be cured with resection of these tumors. In this article, we review the history and current status of metastasectomy in stage IV colorectal cancer.

Abstract
BACKGROUND No differences in response rate (RR), progression-free survival (PFS), overall survival (OS) and quality of life (QoL) were seen in patients randomly treated with biweekly oxaliplatin plus either fluorouracil/folinic acid or capecitabine. METHODS We investigated the independent effect of baseline clinical characteristics and physical functioning (PF) domain on RR, PFS, and OS in 310 patients who completed the EORTC QLQ-C30 questionnaire. Multivariate analyses stratified by treatment were performed. An exploratory analysis was done by grouping patients with a PF score superior or equal to the highest quartile (n = 111), included between the highest and the lowest quartiles (n = 99), or inferior to the lowest quartile (n = 100). The relationship between these three groups and the ECOG PS was then analysed. RESULTS At multivariate analysis, OS was negatively affected by the number of metastatic sites, the serum alkaline phosphatase, and the ECOG PS, while it was positively affected by the previous surgical resection of the primary tumour. Adding the baseline PF score, the number of disease sites (p < 0.0001), the serum alkaline phosphatase (p = 0.0057), and the PF (p = 0.0007) retained an independent significance, while the ECOG PS and the previous surgery were no longer significant. PF did not significantly affect PFS or RR. A good but not totally overlapping correlation was found between PF grouping and ECOG PS score. CONCLUSIONS Baseline self-reported PF independently predicted the OS of patients. Assessment of QoL should be incorporated in randomised trials evaluating the management of patients with MCRC.

Abstract
The treatment options currently available in the medical therapy of advanced colorectal cancer (CRC) appear to be an abundance of riches. The integration of oxaliplatin and irinotecan as conventional cytotoxic agents as well as bevacizumab and the epidermal growth factor receptor (EGFR) antibodies, cetuximab and panitumumab, as novel targeted agents into standard medical therapy have improved median overall survival in metastatic CRC beyond 2 years. It cannot be overemphasized that these significant improvements in outcome of patients with CRC are closely linked to the number of active drugs available to treat this disease. The abundance of treatment options, however, comes with specific challenges for the practical management of palliative medical therapy in advanced CRC, in particular with regard to the utilization of targeted agents. In this context, bevacizumab has established itself as the standard component of first-line chemotherapy. It is of interest for clinical practice that so far no predictive marker for the activity of bevacizumab in metastatic CRC has been identified. The key questions surrounding the use of bevacizumab in the palliative setting are whether its continuation beyond tumor progression provides clinical benefit, and which patient group is at higher risk for bevacizumab-related toxicities. Cetuximab and panitumumab have demonstrated efficacy both in combination with chemotherapy or - in contrast to bevacizumab - as single agent. In unselected patients, the effect of both EGFR antibodies on time-related parameters, progression free survival and overall survival, is moderate at best with emphasis more on the induction of tumor responses in a select group of patients. Therefore, until recently, EGFR antibodies were mainly regarded as salvage therapy options, in particular, since there did not appear to be a loss of activity when used in later lines of therapy. The finding that CRC harboring KRAS (and BRAF) mutations are resistant to EGFR antibodies, has allowed us to enrich the patient population with CRC that have a chance to benefit from cetuximab or panitumumab therapy. Biomarker-based treatment decisions are therefore now an integral part of clinical practice and trial design in CRC. In conclusion, targeted agents have become an integral part of medical therapy for advanced CRC. The challenge for current oncologic practice is to develop a rationale and biomarker-based treatment algorithm utilizing all potentially active agents as individualized therapy.

Abstract
Patients with advanced gastric carcinoma have still had bad prognosis despite advances in the modern treatment era. Docetaxel, cisplatin, 5-fluorouracil (DCF) is effective, but highly toxic regimen for advanced cases. In this study, we modified the standard doses of DCF (mDCF) to evaluate the effectiveness and side effects. From July 2005 to July 2008, 37 advanced gastric cancer patients treated with at least one course of mDCF protocol as first-line treatment were included. The mDCF protocol included 60 mg/m(2) docetaxel and cisplatin for 1 day and 600 mg/m(2)/day, 5-flourouracil infusion for 5 days, repeated every 3 weeks. No patients used prophylactic granulocte -colony stimulating factor. Of the patients, 28 were male and nine were female; the median age was 53 (23-65) years. Of them, 83.8% received at least four courses of chemotherapy and 64.9% completed the preplanned six courses of treatment. Eleven (29.7%) of those patients who received mDCF in the first-line treatment used the FOLFIRI (5-FU, folinic acit, irinotekan) regimen for the second-line treatment. Response rates were evaluated according to RECIST criteria in 30 out of 37 patients. The median follow-up time was 7.1 months. The longest follow-up time was 19.9 months. Two patients (5.4%) had complete response, nine (21.6%) had partial response, and 14 (37.9%) had stabilized disease; overall, the disease was controlled in 25 patients (64.9%) whereas five patients (13.5%) had progression. Median time to progression was 6.7 months and overall survival was 10 months. The assessment of patients for grade 3-4 toxicity revealed that while 5.4% had anemia and 8.1% had neutropenia, 5.4% nausea and 5.4% diarrhea. Neutropenic fever developed in two patients, requiring hospitalization. G-CSF was used in three patients. Two patients with neutropenic fever and two with severe anemia (total number 4; 10.8%) received delayed chemotherapy. Dose reduction was required in four patients (10.8%), one due to neutropenia, one due to nephrotoxicity, and two due to nausea. No patient died due to chemotherapy toxicity. This retrospective study suggested that mDCF might have comparable efficacy with classical DFC, with better toxicity profile. However, its small size and retrospective nature should be considered when interpreting the results.

Abstract
Among the many chemotherapeutic options for metastatic colorectal cancer, none has shown clear superiority in efficacy. All pharmacologic agents in current use have been associated with adverse events. Frequently reported adverse events associated with the chemotherapeutic agents oxaliplatin, irinotecan, 5-fluorouracil, and capecitabine include acute and chronic neuropathy, hypersensitivity reactions, diarrhea, neutropenia, and hand-foot syndrome. Although biologic agents are seemingly less toxic, toxic effects can also arise with their use; antiangiogenic agents result in hypertension, and EGFR inhibitors can cause severe hypersensitivity, paronychial infections, and more commonly, dermatologic rash. Furthermore, a correlation has been reported for the efficacy of anti-EGFR agents and development of rash. Data indicate that elderly patients with colorectal cancer who have adequate function and performance status, who may previously have been dissuaded from pursuing active therapy solely on the basis of age, should receive the same treatment as younger patients. To enhance the survival of patients with metastatic colorectal cancer, many therapies are administered. Recognition of treatment-emergent toxic effects will, therefore, aid the design and implementation of management strategies that minimize treatment interruption and/or discontinuation, and enhance quality of life for patients.

Abstract
There have been many recent advances in the field of systemic chemotherapy for metastatic colorectal cancer. Each treatment affects a different target, including thymidylate synthase, topoisomerase, DNA, the epidermal growth factor receptor, and vascular endothelial growth factor. These treatments have been used in multiple combinations, schedules, and as first-line, second-line, and third-line therapies. The current clinical trials reported can help guide the clinician to determine the appropriate timing, combination, and schedule of chemotherapy agents. Although the decision regarding colorectal cancer chemotherapy is now more complicated, our patients have certainly benefited from better response rates and most importantly, longer survival times.

Abstract
BACKGROUND A phase I study of high-dose capecitabine given over 2 days, along with oxaliplatin, bolus 5FU and leucovorin (LV), was designed to simulate FOLFOX6 without the need for infusional 5FU. METHODS Schedule A included oxaliplatin 100 mg/m(2), 5FU 400 mg/m(2), and LV 20 mg/m(2) (all given IV on days 1 and 15, 28 day cycle). Capecitabine was administered orally every 8 h x 6 doses, days 1 and 15. Schedule B excluded 5FU and LV, maintaining oxaliplatin and capecitabine. Pharmacokinetics were performed for capecitabine for 6 patients on each schedule. RESULTS 36 patients were treated. The dose-limiting toxicities seen included nausea, dehydration, fatigue, hypotension and confusion. Minimal palmar-plantar erythrodysesthesia was seen. Myelosuppression was common, but not a dose limiting toxicity. The pharmacokinetic parameters for capecitabine were unaltered. CONCLUSION Using capecitabine to mimic FOLFOX6 is feasible and well tolerated with a toxicity profile that differs from standard 14-day capecitabine dosing, with less palmar-plantar erythrodysesthesia. The phase II dose for capecitabine in combination with oxaliplatin, 5FU, and LV is 1,500 mg/m(2)/dose or 2,250 mg/m(2)/dose in the absence of bolus 5FU/LV.

Abstract
BACKGROUND Long-term survival of patients with ovarian cancer remains poor and therapy disappointing despite decades of experience with various chemotherapies, including the current gold standard, carboplatin/paclitaxel (TC). OBJECTIVE To review current and emerging therapies for ovarian cancer in search of ways to improve outcome, reduce toxicity, and maintain quality of life. METHODS This is a review of the current status of chemotherapy for ovarian cancer, the ongoing clinical studies, emerging therapies, and proposals for future research. RESULTS/CONCLUSION Novel chemotherapeutic agents are needed to reduce toxicity and improve efficacy. Effective biological agents must be found and tested, either in combination with TC or as maintenance therapy after TC. An appropriate regimen and number of repeat treatment cycles for intraperitoneal chemotherapy is urgently needed, and an effective regimen must be established for patients with clear cell/mucinous adenocarcinoma. The main strategy for recurrent ovarian cancer is to find the gene related to drug resistance, then treat the cancer based on its molecular biology.

Abstract
Colorectal cancer is the fourth most common noncutaneous malignancy in the United States and the second most frequent cause of cancer-related death. Over the past 12 years, significant progress has been made in the systemic treatment of this malignant condition. Six new chemotherapeutic agents have been introduced, increasing median overall survival for patients with metastatic colorectal cancer from less than 9 months with no treatment to approximately 24 months. For patients with stage III (lymph node positive) colon cancer, an overall survival benefit for fluorouracil-based chemotherapy has been firmly established, and recent data have shown further efficacy for the inclusion of oxaliplatin in such adjuvant treatment programs. For patients with stage II colon cancer, the use of adjuvant chemotherapy remains controversial, but may be appropriate in a subset of individuals at higher risk for disease recurrence. Ongoing randomized clinical trials are evaluating how best to combine currently available therapies, while smaller studies are evaluating new agents, with the goal of continued progress in prolonging life among patients with metastatic colorectal cancer and increasing cure rates among those with resectable disease.

Abstract
PURPOSE Quality of life (QOL) measures are critical to the evaluation of new cancer treatments, particularly for elderly patients. Our intent was to assess patterns of use of QOL endpoints in colorectal cancer (CRC) treatment research and to summarize current knowledge about how CRC treatment affects elderly patients. PATIENTS AND METHODS We searched MEDLINE for English-language, human trials published from 1995 to 2005 that met the following criteria: reported on patients with CRC, were not surgery-only cohorts, and included a QOL or functional endpoints. Trials specifically reporting data on elderly patients were reviewed in depth and summarized. RESULTS One hundred twenty-one eligible studies and 10 trials with elderly-specific data were found. The median number of trials published annually increased from 5 (range, 4-8 trials) between 1995 and 1999 to 14.5 (range, 11-22 trials) between 2000 and 2005. Chemotherapy was the most commonly studied treatment (55%), and metastatic CRC (55%) was the most commonly studied population. The European Organization for Research and Treatment of Cancer C30, with or without C38, was the most frequently used instrument (49%). Studies reporting on elderly patients showed that many patients experience a decline in physical function immediately after surgery and have increased need for supportive services. Little information is available on the effect of chemotherapy in elderly patients. Use of QOL and functional measures in treatment-related CRC research has increased; however, it continues to be hampered by a lack of dissemination and methodologic problems. CONCLUSION Missing data from patient attrition, limitations of assessment methods, and a small number of patients treated with chemotherapy in the trials reporting on elderly patients seriously limit our ability to draw conclusions from this survey about how treatment affects QOL or function in CRC.
