Abstract
STUDY AIM ModraDoc006, an oral formulation of docetaxel, is co-administered with the cytochrome P450-3A4 and P-glycoprotein inhibitor, ritonavir (r): ModraDoc006/r. The preliminary efficacy and safety of oral ModraDoc006/r was evaluated in a global randomized phase II trial and compared to the current standard chemotherapy regimen of intravenous (i.v.) docetaxel and prednisone. METHODS 103 mCRPC patients, chemotherapy-naïve with/without abiraterone and/or enzalutamide pretreated, with adequate organ function and evaluable disease per RECIST v1.1 and PCWG3 guidelines were randomized 1:1 into two cohorts. In Cohort 1, 49 patients received docetaxel 75 mg/m2 i.v. every 3 weeks (Q3W). In Cohort 2, 52 patients received ModraDoc006/r; 21 patients with a starting dose of ModraDoc006 30 mg with ritonavir 200 mg in the morning and ModraDoc006 20 mg with ritonavir 100 mg in the evening (30-20/200-100 mg) bi-daily-once-weekly (BIDW) on Days 1, 8, and 15 of a 21-day cycle. To alleviate tolerability, the starting dose was amended to ModraDoc006/r 20-20/200-100 mg in another 31 patients. All patients received prednisone 10 mg daily. Primary endpoint was rPFS. RESULTS There was no significant difference in rPFS between the 2 arms (p = 0.1465). Median rPFS was 9.5 months and 11.1 months (95% CI) for ModraDoc006/r and i.v. docetaxel, respectively. Partial response was noted in 44.1% and 38.7% measurable disease patients, and 50% decline of PSA was seen in 23 (50%) and 26 (56.5%) evaluable cases treated with ModraDoc006/r and i.v. docetaxel, respectively. The safety profile of ModraDoc006/r 20-20/200-100 mg dose was significantly better than i.v. docetaxel, with mild (mostly Grade 1) gastrointestinal toxicities, no hematologic adverse events, and neuropathy and alopecia incidence of 11.5% and 25%, respectively. CONCLUSIONS ModraDoc006/r potentially represents a widely applicable, convenient, effective, and better tolerated oral taxane therapy option for mCRPC. Further investigation of ModraDoc006/r in a large randomized trial is warranted.

Abstract
This study conducted a cost-utility analysis and a budget impact analysis (BIA) of outpatient oral chemotherapy versus inpatient intravenous chemotherapy for stage III colorectal cancer (CRC) in Thailand. A Markov model was constructed to estimate the lifetime cost and health outcomes based on a societal perspective. Eight chemotherapy strategies were compared. Clinical and cost data on adjuvant chemotherapy were collected from the medical records of 1747 patients at Siriraj Hospital, Thailand. The cost-effectiveness results were interpreted against a Thai willingness-to-pay threshold of USD 5003/quality-adjusted life year (QALY) gained. A 5-year BIA was performed. Of the eight strategies, CAPOX then FOLFIRI yielded the highest life-year and QALY gains. Its total lifetime cost was also the highest. An incremental cost-effectiveness ratio of CAPOX then FOLFIRI compared to 5FU/LV then FOLFOX, a commonly used regimen USD was 4258 per QALY gained.The BIA showed that when generic drug prices were applied, 5-FU/LV then FOLFOX had the smallest budgetary impact (USD 9.1 million). CAPOX then FOLFIRI required an approximately three times higher budgetary level (USD 25.1 million). CAPOX then FOLFIRI is the best option. It is cost-effective compared with 5-FU/LV then FOLFOX. However, policymakers should consider the relatively high budgetary burden of the CAPOX then FOLFIRI regimen.

Abstract
We examine provider responses to the expansion of public subsidies in 2015 for innovative oral chemotherapy treatment, in a health system where providers were free to determine their own prices. The new treatment was known to have similar efficacy to its traditional intravenous alternative and was preferred by patients for its at-home administration. However, from a policymaker's perspective, the potential for misalignment between patient and provider preferences was significant given the shift to full reimbursement for the oral chemotherapy medication but no change in fee-for-service payments for associated chemotherapy services. Under this scenario, a shift away from traditional intravenous chemotherapy may entail reduced activity and revenues associated with infusions for providers, and we hypothesise that it may result in unintended policy consequences such as reduced take-up of the new therapy or higher prices. We implement a difference-in-difference model using national administrative data on services provided, and chemotherapy medications prescribed, by providers to 1850 patients in New South Wales, Australia. Our estimates indicate that the subsidies expanded access to oral chemotherapy for newly eligible patients by 15 percentage points. However, prices charged by providers for an episode of care rose by 23 percent, driven mostly by increases in service volumes. The results illustrate the importance of understanding differential provider responses to policy changes in financial incentives.

Abstract
Doxorubicin (DOX), a widely used drug in cancer chemotherapy, induces cell death via multiple intracellular interactions, generating reactive oxygen species and DNA-adducted configurations that induce apoptosis, topoisomerase II inhibition, and histone eviction. Despite its wide therapeutic efficacy in solid tumors, DOX often induces drug resistance and cardiotoxicity. It shows limited intestinal absorption because of low paracellular permeability and P-glycoprotein (P-gp)-mediated efflux. We reviewed various parenteral DOX formulations, such as liposomes, polymeric micelles, polymeric nanoparticles, and polymer-drug conjugates, under clinical use or trials to increase its therapeutic efficacy. To improve the bioavailability of DOX in intravenous and oral cancer treatment, studies have proposed a pH- or redox-sensitive and receptor-targeted system for overcoming DOX resistance and increasing therapeutic efficacy without causing DOX-induced toxicity. Multifunctional formulations of DOX with mucoadhesiveness and increased intestinal permeability through tight-junction modulation and P-gp inhibition have also been used as orally bioavailable DOX in the preclinical stage. The increasing trends of developing oral formulations from intravenous formulations, the application of mucoadhesive technology, permeation-enhancing technology, and pharmacokinetic modulation with functional excipients might facilitate the further development of oral DOX.

Abstract
OBJECTIVE The aims of this study was to appraise the health economic evidence for adjuvant chemotherapy (AC) strategies in stage II and III colon cancer (CC) and identify gaps in the available evidence that might inform further research. METHOD A systematic review of published economic evaluations was undertaken. Four databases were searched and full-text publications in English were screened for inclusion. A narrative synthesis was performed to summarise the evidence. RESULTS Thirty-eight studies were identified and stratified by cancer stage and AC strategy. The majority (89%) were full economic evaluations considering both health outcomes, usually measured as quality-adjusted life years (QALYs), and costs. AC was found to be cost-effective compared to no AC for both stage II and III CC. Oral and oxaliplatin-based AC was cost-effective for stage III. Three months of CAPOX was cost-effective compared to 6-month in high-risk stage II and stage III CC. Preliminary evidence suggests that biomarker approaches to AC selection in stage II can reduce costs and improve health outcomes. Notably, assessment of QALYs were predominantly reliant on a small number of non-contemporary health-utility studies. Only 32% of studies considered societal costs such as travel and time off work. CONCLUSIONS Published economic evaluations consistently supported the use of AC in stage II and III colon cancer. Biomarker-driven approaches to patient selection have great potential to be cost-effective, but more robust clinical and economic evidence is warranted. Patient surveys embedded into clinical trials may address critical knowledge gaps regarding accurate assessment of QALYs and societal costs in the modern era.

Abstract
OBJECTIVES The current standard treatment for patients with rectal cancer stage II-III is neoadjuvant chemoradiotherapy followed by surgery. Neoadjuvant chemoradiotherapy can be performed with 5-fluorouracil (5-FU) or capecitabine (CPC) considered to be equivalent therapies. Medication cost is higher for CPC than for 5-FU, however, the administration of continuous 5-FU intravenous infusion is related to other costs such as those associated with outpatient facilities or central venous catheter insertion. METHODS This retrospective study analysed the direct sanitary costs associated with the treatments and their complications from a hospital perspective. Costs in patients treated with 5-FU or CPC were measured between January 2010 and July 2018 at Mataró Hospital. The aim of this study was to perform a cost-minimisation analysis between the two treatments. We aimed to assess the cost associated with the complications related to each drug and the economic impact of applying the most efficient option. RESULTS Ninety-eight patients were analysed: 32 were treated with CPC and 66 with 5-FU. Treatment cost was significantly higher for 5-FU than for CPC (2560.86±99.17 and 563.10±9.52 respectively, P=0.0001). No significant differences were found in the costs associated with treatment complications between groups (148.21±934.91 and 41.41±102.50 euros respectively, P=0.322). CONCLUSIONS Considering the clinical equivalence shown in the available trials and previous reviews, the most efficient treatment is neoadjuvant chemoradiotherapy with CPC. Complications associated with the treatments did not significantly modify these results. Other studies gave similar results both in the neoadjuvant and adjuvant context, reaffirmed in this study.

Abstract
BACKGROUND Hand-foot syndrome (HFS) is a specific adverse effect of certain chemotherapy that may lead to dosage reduction or chemotherapy discontinuation in patients with cancer. Topical urea cream may reduce symptom severity in patients with HFS. However, these studies have not provided consonant results. OBJECTIVE To determine the effectiveness of urea cream, we conducted a meta-analysis of clinical trials to evaluate the prevention and treatment of HFS. METHODS PubMed, EMBASE, and Cochrane Library databases were searched for studies published before September 2020. The study registered at PROSPERO (CRD 42020203164). Incidence of HFS reported in studies at any grade and at second grade or greater was assessed within 3 to 12 weeks. Secondary outcomes were time to HFS, incidence of skin-related adverse events, chemotherapy dose reduction, and quality of life. RESULTS Seven trials involving 1387 patients were reviewed. In the prophylactic subgroup, patients with urea cream intervention showed a significantly lower incidence of HFS at second grade or greater (risk ratio, 0.72; 95% confidence interval, 0.58-0.90) and a nonsignificant lower incidence of any-grade HFS (risk ratio, 0.79; 95% confidence interval, 0.58-1.08) than those not receiving urea cream intervention. CONCLUSIONS Urea cream has advantages to reduce the incidence of severe HFS. IMPLICATIONS FOR PRACTICE Urea cream is a safe and viable topical prevention strategy that can reduce the incidence of high-grade HFS in patients undergoing chemotherapy. We recommend a routine treatment option before chemotherapy for the patients.

Abstract
BACKGROUND Suboptimal completion of chemotherapy, which may involve reduced patient adherence, remains a serious issue and leads to reduced treatment efficacy. This study assessed the completion rates, risk factors for noncompletion, and cost impact for noncompletion in patients on capecitabine monotherapy (Cape) or capecitabine with oxaliplatin (CAPOX) for the adjuvant treatment of early-stage colon cancer. METHODS Patients with a diagnosis of early-stage colon cancer between April 2013 and March 2017 were retrospectively identified. Treatment completion was evaluated. Multivariate logistic regressions analyses were used to assess the baseline factors associated with noncompletion. Adverse events, costs, healthcare resource utilization, and cost impact for noncompletion were investigated. RESULTS A total of 673 patients met the eligibility criteria, of which 382 (57%) were treated with Cape and 291 (43%) with CAPOX. The overall completion rate for adjuvant therapy was 40% (Cape 46%; CAPOX 33%). Noncompletion was associated with CAPOX treatment and higher healthcare costs within 6 months prior to chemotherapy. The 6-month unadjusted total healthcare costs were $44,444 for Cape and $71,247 for CAPOX. The nonchemotherapy costs were 41% higher for noncompleters than completers in both treatment groups (P = .002). CONCLUSIONS The real-world completion rates for adjuvant capecitabine-based chemotherapy in early-stage colon cancer patients are low. Noncompletion of therapy is associated with higher baseline healthcare costs. The nonchemotherapy costs are significantly higher in noncompleters than completers, highlighting the financial burden of managing adverse events and preexisting comorbidities, which may lead to early discontinuation of therapy. Effective strategies to optimize completion of oral chemotherapy may consider adherence monitoring.

Abstract
Cancer patients experienced an increased risk of cardiotoxicity during fluoropyrimidine-based chemotherapy (5-fluorouracil or capecitabine). We searched PubMed, PsycINFO, IPA, CINAHL, Web of Science, and ClinicalTrials.gov for studies published between January 1, 1990 and December 31, 2019, in English, examining risk factors for cardiotoxicity induced by fluoropyrimidine. Included study-level data were converted to risk ratios (RRs) and pooled RRs were calculated for meta-analyses using a random-effects method. Among 690 publications identified for abstract and title screening, 22 unique studies were included in the review, and 20 had sufficient data for meta-analyses. Results indicated that patients undergoing capecitabine-based combination therapy had a higher risk than those with monotherapy (pooled RR = 1.61). Patients with pre-existing cardiac disease (pooled RR = 3.26), hypertension (pooled RR = 1.52) or smoking (pooled RR = 2.22) also had higher risks than their counterparts. Developing risk assessment tools to mitigate the risk could be a viable strategy to improve outcomes for cancer patients undergoing fluoropyrimidine-based treatments.

Abstract
In Europe, inappropriate reimbursement and funding rules and regulations act as disincentives to best breast cancer care or, at worst, hinder best care. This problem was the focus of the 12th European Breast Cancer Conference (EBCC) manifesto, discussed during the virtual conference. As patient involvement is indispensable in driving changes to clinical practice, Europa Donna the European patient advocacy group was closely involved in the 12th manifesto. Reimbursement policies have rarely evolved with advances in breast cancer care such as outpatient (ambulatory) care rather than inpatient admission, use of oral or subcutaneous anti-cancer drugs rather than day-hospital intravenous administration, oncoplastic surgery techniques to minimize mastectomy rates, breast reconstructive surgery, risk-reducing surgery for BRCA mutation carriers, or use of hypo-fractionated breast radiation therapy. Although each European country, region and centre will have to understand how their reimbursement policies may hinder best care and find their own solutions, the problems are similar throughout Europe and some solutions can be broadly applied. This manifesto is not calling for more funding or demanding changes that will result in more expensive care. Reimbursement, if better aligned with guidelines and optimal clinical practice, will deliver more cost-effective healthcare. This will release resources, support more equitable use of finite funding and resources, so allowing more European breast cancer patients to benefit from evidence-based treatment recommended by national and international guidelines.

Abstract
INTRODUCTION Capecitabine is an oral anticancer drug which can cause some adverse reactions and the great challenge for its use is to ensure the medication adherence. The aim of this study was to analyze adverse reactions and adherence to capecitabine in patients with gastrointestinal cancer. METHODS A prospective study was performed in a tertiary teaching hospital in Brazil. Outpatients undergoing capecitabine treatment for colorectal or gastric cancer were followed for three cycles of treatment. Patient demographic and clinical characteristics data were collected. Adverse reactions were analyzed using Common Terminology Criteria for Adverse Events (CTCAE) v.4. Adherence to capecitabine were evaluated using Morisky-Green and MedTake tests. Statistical analysis was conducted using Chi-square, Fisher's exact and McNemer tests. RESULTS One hundred and four patients were enrolled in this study, with a mean age was 58.5 ± 10.9 years; 51.0% were men and 51.0% Caucasian. Nausea and diarrhea were the most frequently reported adverse reactions (82.7% and 62.5%, respectively), followed by vomiting (54.8%), fatigue (54.8%), and hand-foot syndrome (53.9%). Nausea and diarrhea were also the most severe adverse reactions. Most patients were adherent to capecitabine in all cycles of treatment using the Morisky-Green test. Adherence increased significantly between cycle 1 and cycle 2 by MedTake test (p < 0.001). Some demographic and clinical characteristics were associated with adverse reactions (e.g., age and nausea, gender and nausea and vomiting) and capecitabine adherence (e.g., marital status and educational level) as well as some adverse reactions were associated with capecitabine adherence (hand-foot syndrome and nausea). CONCLUSIONS Clinical oncology pharmacists must provide patient information on the correct use of capecitabine, manage adverse reactions, and monitor adherence to treatment. Strategies to prevent non-adherence to capecitabine must be adopted to ensure the success of pharmacotherapy.

Abstract
The taxanes paclitaxel, docetaxel and cabazitaxel are important anticancer agents that are widely used as intravenous treatment for several solid tumor types. Switching from intravenous to oral treatment can be more convenient for patients, improve cost-effectiveness and reduce the demands of chemotherapy treatment on hospital care. However, oral treatment with taxanes is challenging because of pharmaceutical and pharmacological factors that lead to low oral bioavailability. This review summarizes the current clinical developments in oral taxane treatment. Intravenous parent drugs, strategies in the oral switch, individual agents in clinical trials, challenges and further perspectives on treatment with oral taxanes are subsequently discussed.

Abstract
Surgical resection and adjuvant chemotherapy are the only treatment modalities for localized colorectal cancer that can obtain a "cure." The goal in surgically treating primary colorectal cancer is complete tumor removal along with dissection of systematic D3 lymph nodes. Adjuvant treatment controls recurrence and improves the prognosis of patients after they undergo R0 resection. Various clinical studies have promoted the gradual spread and clinical use of new surgical approaches such as laparoscopic surgery, robotic surgery, and transanal total mesorectal excision (TaTME). Additionally, the significance of adjuvant chemotherapy has been established and it is now recommended in the JSCCR (the Japanese Society for Cancer of the Colon and Rectum) guideline as a standard treatment. Herein, we review and summarize current surgical treatment and adjuvant chemotherapy for localized colorectal cancer and discuss recent advances in personalized medicine related to adjuvant chemotherapy.

Abstract
Adjuvant chemotherapy with capecitabine is frequently not completed due to adverse events, including hand-foot syndrome. A higher completion rate of capecitabine by reduction of the side effects may improve disease-free survival and quality of life of affected patients. In the present study, colorectal cancer (CRC) patients were treated with capecitabine (2,500 mg/m2/day), which was taken for five days, followed by an interval of two days (5-days-on/2-days-off schedule). One course lasted three weeks, and eight courses (24 weeks) were administered. The median number of treatment courses was significantly higher in patients in the 5-days-on/2-days-off regimen group compared with that of patients in the retrospectively included conventional regimen group (P=0.0438). The frequency of completion of the scheduled treatment by patients in the 5-days-on/2-days-off regimen group was significantly higher (P=0.0389). The present phase II study suggests that toxicities associated with the 5-days-on/2-days-off regimen are lower compared with those of the conventional regimen, and that the occurrence of adverse events was higher, but less high-grade toxicities were reported. The time to treatment failure was also favorable in the new regimen and it demonstrated good feasibility. In conclusion, the present study demonstrated good feasibility with retained quality of life and acceptable adverse effects (mostly low-grade), and the 5-days-on/2-days-off regimen should be further evaluated in future randomized controlled trials. The present study was registered in the University Hospital Medical Information Network (UMIN) clinical trial registry (no. UMIN000012813).

Abstract
BACKGROUND The Short Course Oncology Therapy (SCOT) study is an international, multicentre, non-inferiority randomised controlled trial assessing the efficacy, toxicity, and cost-effectiveness of 3 months (3 M) versus the usually given 6 months (6 M) of adjuvant chemotherapy in colorectal cancer. METHODS In total, 6088 patients with fully resected high-risk stage II or stage III colorectal cancer were randomised and followed up for 3–8 years. The within-trial cost-effectiveness analysis from a UK health-care perspective is presented using the resource use data, quality of life (EQ-5D-3L), time on treatment (ToT), disease-free survival after treatment (DFS) and overall survival (OS) data. Quality-adjusted partitioned survival analysis and Kaplan–Meier Sample Average Estimator estimated QALYs and costs. Probabilistic sensitivity and subgroup analysis was undertaken. RESULTS The 3 M arm is less costly (-£4881; 95% CI: -£6269; -£3492) and entails (non-significant) QALY gains (0.08; 95% CI: −0.086; 0.230) due to a better significant quality of life. The net monetary benefit was significantly higher in 3 M under a wide range of monetary values of a QALY. The subgroup analysis found similar results for patients in the CAPOX regimen. However, for the FOLFOX regimen, 3 M had lower QALYs than 6 M (not statistically significant). CONCLUSIONS Overall, 3 M dominates 6 M with no significant detrimental impact on QALYs. The results provide the economic case that a 3 M treatment strategy should be considered a new standard of care.

Abstract
PURPOSE The aim of this study was to evaluate whether pretreatment analysis of selected molecular markers can be used for the prediction of disease-free survival (DFS)/overall survival (OS) of capecitabine adjuvant monotherapy in colon cancer patients. PATIENTS AND METHODS A total of 126 patients enrolled in a capecitabine Phase IV clinical trial were analyzed for microsatellite instability (MSI), 18q loss of heterozygosity (LOH), thymidylate synthase (TYMS) 5' variable number of tandem repeat (VNTR), and methylene tetrahydrofolate reductase (MTHFR) C677T variants. The significance in predicting 5-year DFS/OS was assessed by Kaplan-Meier and Cox regression analyses. RESULTS The MSI-high (MSI-H) genotype was significantly associated with DFS (HR 0.205, 95% CI 0.05-0.88, P=0.033) and OS (HR 0.208, 95% CI 0.05-0.89, P=0.035) compared to the microsatellite stable genotype. In models stratified according to clinicopathologic characteristics, the MSI-H genotype remained a positive predictive factor for DFS/OS only in patients with stage III (P=0.023) and patients with tumors localized proximally to the splenic flexure (P=0.004). Distal colon cancers with 18q LOH have a greater survival rate when treated with capecitabine than patients with stable tumors (81.3% vs 50.0%, HR for relapse 0.348, 95% CI 0.13-0.97, P=0.043). TYMS 5'VNTR and MTHFR C677T variants were not associated with DFS or OS. CONCLUSION MSI and 18q LOH markers have the potential to be utilized in the selection of colon cancer patients eligible for capecitabine adjuvant monotherapy.

Abstract
OBJECTIVES To review literature characteristics, describe methodological trends, and assess the reporting quality of the economic evaluations of oral anticancer drugs (OACDs). METHODS The review included comparative economic evaluations of OACDs. The search was conducted via PubMed, Embase, EconLit, and Economic Evaluation Database, and studies till December 2017 were included. Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist, literature inclusion and data extraction were performed in duplicate by separate investigators. Outcome measures were literature characteristics, gaps and methodological trends, and reporting quality using the Consolidated Health Economic Evaluation Reporting Standards checklist. Data were summarized on the basis of methodological themes of interest. Descriptive statistics and tabulations were used for result presentation. RESULTS Out of 241 found articles, 21 were included. There is a recent increasing interest in the economics of OACDs, whereby the cost per quality-adjusted life-year, via cost-utility analysis, is the most used for decision making. Most of the studies were from the payer perspective, and the primary sources of data were clinical trials, expert panels, and medical charts. The dominance status (higher effect, lower cost) was a commonly reported outcome. Decision-analytic modeling was used in most of the studies, mostly including Markov modeling. Studies were highly heterogeneous in methodological aspects, and the included studies did not meet most of the reporting quality criteria. CONCLUSIONS High heterogeneity in methods in studies may limit the robustness and transferability of results, potentially misleading decision makers toward wrong decisions on OACDs. The transferability and generalizability of results are further limited by a "less than ideal" adherence to current reporting standards.

Abstract
Background Adjuvant chemotherapy at concurrent time with radiation therapy (RT) or at adjuvant time alone in locally advanced rectal cancer (LARC) is used with several regimens. The cost-utility analysis was conducted to compare administration of two 5-FU regimens and capecitabine in the aspect of provider and societal viewpoint. Methods Stage II or III rectal cancer patients who received pre-operative or post-operative concurrent chemoradiotherapy and adjuvant chemotherapy were compared by using decision tree model between (I) 5-FU plus leucovorin (LV) for 5 days per cycle (Mayo Clinic regimen); (II) 5-FU continuous infusion (CI) for 120-h per cycle (CAO/ARO/AIO-94 protocol); (III) standard regimen of capecitabine. All probability data were extracted from landmark study. Direct medical costs were the cost from database of Drug Medical Supply Information Center, while direct non-medical cost and utility were interviewed from stage II and III rectal cancer patients. The time horizon of this study was 5 years. Incremental cost-effectiveness ratio (ICER) was the final result in this study, which determined as the numerator of the difference of costs among three drug regimens, and the difference of quality-adjusted life years (QALYs) from each drug was the denominator. Results 5-FU plus LV was the cheapest and least efficacy for adjuvant treatment of LARC in both provider and societal viewpoint. In provider viewpoint, the ICERs of 5-FU CI and capecitabine were 334,550 THB/QALY (US $9,840/QALY) and 189,935 THB/QALY (US $5,586/QALY), respectively, with the corresponding societal viewpoint of 264,447 THB/QALY (US $7,778/QALY) and 119,120 THB/QALY (US $3,504/QALY) when 5-FU plus LV was used as comparator. The most influential parameter for value of treatment was acquisition cost of capecitabine. At the willingness to pay for one QALY gained in Thailand (160,000 THB or US $4,706), 5-FU plus LV, 5-FU CI and capecitabine had probabilities of cost-effectiveness of 63%, 2% and 35%, respectively. Conclusions Capecitabine was the most expensive regimen but produced the higher effectiveness than 5-FU plus LV and 5-FU CI. The most influential parameter in the model was acquisition cost of capecitabine.

Abstract
Adherence has become an important issue in modern oncology treatment. Most studies have included heterogeneous target tumor types, regimens, and therapy settings. Our study focused on capecitabine during capecitabine plus oxaliplatin (XELOX) treatment as an adjuvant therapy for colorectal cancer. The main aims of this study were to evaluate real-life adherence to capecitabine and to investigate candidate factors that might decrease adherence. We studied 338 consecutive patients who received XELOX treatment between December 1, 2011, and April 30, 2015, at the Cancer Institute Hospital of the Japanese Foundation for Cancer Research. Our study assessed adherence to capecitabine through patient-reported treatment diaries and interviewed nonadherents to determine the reasons for not taking capecitabine at a pharmaceutical outpatient clinic. We calculated the adherence rate in a cycle as: number of times the patient took capecitabine/28. Relative dose intensities and factors associated with deteriorating adherence to capecitabine were retrospectively surveyed from electronic patient records. Uni- and multivariate logistic regression analyses were used to investigate factors associated with optimal adherence. The study covered 282 patients who received 2,055 cycles of XELOX. Median adherence rate was 94.0% in the first cycle, and median relative dose intensity of capecitabine was 77.8%. The most common reasons for nonadherence were nausea/vomiting and diarrhea. The presence of the following factors was not significantly associated with adherence: ECOG performance status ≥1 (p = 0.715), clinical stage (p = 0.408), primary tumor site (p = 0.576), age ≥70 years at study entry (p = 0.757), female gender (p = 0.504), and not living alone (p = 0.579). The adherence rate from this study was significantly higher than the adherence from metastatic settings. Adherence-enhancing interventions for capecitabine in XELOX treatment as adjuvant therapy comprised management of nausea/vomiting and diarrhea.

Abstract
Modern chemotherapy agents transformed standard care for metastatic colorectal cancer (mCRC) but raised concerns about the financial burden of the disease. We studied comparative effectiveness of treatment plans that involve up to three lines of therapies and impact of treatment sequencing on health and cost outcomes. We employed a Markov model to represent the dynamically changing health status of mCRC patients and used Monte-Carlo simulation to evaluate various treatment plans consistent with existing guidelines. We calibrated our model by a meta-analysis of published data from an extensive list of clinical trials and measured the effectiveness of each plan in terms of cost per quality-adjusted life year. We examined the sensitivity of our model and results with respect to key parameters in two scenarios serving as base case and worst case for patients' overall and progression-free survivals. The derived efficient frontiers included seven and five treatment plans in base case and worst case, respectively. The incremental cost-effectiveness ratio (ICER) ranged between $26,260 and $152,530 when the treatment plans on the efficient frontiers were compared against the least costly efficient plan in the base case, and between $21,256 and $60,040 in the worst case. All efficient plans were expected to lead to fewer than 2.5 adverse effects and on average successive adverse effects were spaced more than 9 weeks apart from each other in the base case. Based on ICER, all efficient treatment plans exhibit at least 87% chance of being efficient. Sensitivity analyses show that the ICERs were most dependent on drug acquisition cost, distributions of progression-free and overall survivals, and health utilities. We conclude that improvements in health outcomes may come at high incremental costs and are highly dependent in the order treatments are administered.

Abstract
Micro-abstract In a Phase I dose-finding study of metronomic daily oral vinorelbine in advanced non-small-cell lung cancer, a recommended dose was established for this therapeutic approach. In addition, this trial revealed promising efficacy data and an acceptable tolerability profile. The observed vinorelbine blood concentrations suggest continuous anti-angiogenic coverage. Introduction We present a Phase I dose-finding study investigating metronomic daily oral vinorelbine (Navelbine® Oral, NVBo) in advanced non-small-cell lung cancer (NSCLC). Patients and methods Patients with stage III/IV NSCLC received daily NVBo at fixed dose levels of 20–50 mg/d for 21 days of each 4-week cycle. Primary end point was the maximum tolerated dose. Secondary end points included tumor response, time to progression (TTP), overall survival (OS) and tolerability. Results Twenty-seven patients with advanced NSCLC were enrolled. Most of them were extensively pretreated. Daily NVBo was well tolerated up to 30 mg/d. At 40 mg/d, two of five patients experienced dose-limiting toxicities (DLTs). Three of six patients had DLTs at the 50 mg/d level. The recommended dose was established at 30 mg/d in cycle 1, with escalation to 40 mg/d in cycle 2, if tolerated. Pharmacokinetic analyses showed continuous blood exposure over 21 days and only marginal accumulation. The tolerability profile was acceptable (all dose levels – all grades: decreased appetite 33%, diarrhea 33%, leukopenia 33%, nausea 30%, vomiting 26%; ≥grade 3: leukopenia 30%, lymphopenia 19%, neutropenia 19%, febrile neutropenia 15%). Disease control rate, OS and TTP signaled a treatment effect. Conclusion Daily metronomic NVBo therapy in extensively pretreated patients with advanced NSCLC is feasible and safe at the recommended dose of 30 mg/d. Escalation to 40 mg/d in the second cycle is possible. The blood concentrations of vinorelbine after daily metronomic dosing reached lower peaks than intravenous or oral conventional dosing. Blood concentrations were consistent with anti-angiogenic or immune modulating pharmacologic properties of vinorelbine. Further studies are warranted to evaluate the safety and efficacy of this novel approach in specific patient populations.

Abstract
Introduction: Capecitabine is a widely prescribed oral anticancer agent. We studied medication adherence and explored its use in daily practice from a patients' perspective. Patients and Methods: Patients (n = 92) starting capecitabine were followed up to five 3-week cycles. Adherence was assessed using a pill count, pharmacy data and dosing information from the patients' medical file. Self-reported adherence was measured using the Medication Adherence Report Scale (MARS). At baseline and during week 2 of cycles 1, 3, and 5, patients filled out questionnaires about quality of life, symptoms, attitude toward medicines and disease and use in daily practice. Simultaneously, blood samples were taken to determine the area under the curve (AUC) of 5′-deoxy-5-fluorouridine (5′-DFUR), 5-fluorouracil (5-FU), and α-fluoro-β-alanine (FBAL) by a population pharmacokinetic model. Associations between AUCs and patient-reported symptoms were tested for cycles 3 and 5. Results: Most patients (84/92; 91%) had an adherence rate of ≥95 and ≤ 105%. The percentage of patients reporting any non-adherence behavior measured with MARS increased from 16% at cycle 1 to 29% at cycle 5. Symptoms were reported frequently and the dosing regimen was adjusted by the physician at least once in 62% of patients. In multivariate analysis the probability of an adjustment increased with the number of co-medication (OR 1.19, 95% CI: 1.03–1.39) and a stronger emotional response to the disease (OR 1.32, 95% CI: 1.10–1.59). The AUC of 5′-DFUR was associated with weight loss (OR 1.10, 95% CI: 1.01–1.19), AUC of FBAL with hand-foot syndrome (OR 0.90, 95% CI: 0.83–0.99), rhinorrhea (OR 1.21, 95% CI: 1.03–1.42 weight loss (OR 1.09, 95% CI: 1.00–1.20) and depression (OR 0.90, 95% CI: 0.82–0.99). Side effects were reported by one third of patients as the reason to discontinue treatment. Conclusion: Adherence to capecitabine was generally high. Nevertheless, adherence measured with MARS decreased over time Adherence management to support implementation of correct capecitabine use is specifically relevant in longer term treatment. In addition, it appears that adverse event management is important to support persistence. With the extending armamentarium of oral targeted anticancer agents and prolonged treatment duration, we expect the issue of medication adherence of increasing importance in oncology.

Abstract
BACKGROUND There are no randomized phase III trials comparing 5-fluorouracil/mitomycin (FM) versus capecitabine/mitomycin (CM) in combination with radiotherapy (RT) for locally advanced anal cancer. We aim to evaluate the outcomes of patients treated with FM and CM at our institution. METHODS Patients with stage I-III anal cancer who initiated curative-intent RT (50-54 Gy) with either CM or FM between 1998 and 2013 at the BC Cancer Agency were reviewed. Cox proportional models were used to analyze the impact of regimen on disease-free survival (DFS) and anal cancer-specific survival (ACSS). RESULTS A total of 300 patients were included. Baseline characteristics were well-distributed between the groups. A total of 194 patients (64.6%) received FM and 106 (35.3%) CM. The 2-year DFS was 79.7% for CM [95% confidence intervals (95% CI), 71.1-88.3%] and 78.8% for FM (95% CI, 73-84.6%); 2-year ACSS was 88.7% for CM (95% CI, 81.8-95.5%) and 87.5% for FM (95% CI, 82.8-92.2%). On multivariate analysis, only HIV status, clinical T size (≤5 vs. >5 cm), and N status (negative vs. positive) remained as significant prognostic factors for both DFS and ACSS. Chemotherapy regimen (CM vs. FM) had no impact on either DFS [P=0.995; hazard ratios (HR) =0.99; 95% CI, 0.57-1.74] or ACSS (P=0.847; HR =0.93; 95% CI, 0.46-1.86). CONCLUSIONS In our population-based study, CM and FM concomitant with RT achieved similar DFS and ACSS. Substitution of capecitabine for infusional 5-FU may therefore be a reasonable option for patients and physicians who prefer to avoid the inconvenience and potential complications of a central infusional device.

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
PURPOSE For over 50 years, 5-FU has played a critical role in the systemic chemotherapy of cancer patients. 5-FU serves as the main backbone of combination chemotherapy for patients with colorectal cancer in both the adjuvant and metastatic disease settings. Herein, we review the current status of 5-FU therapeutic drug monitoring (TDM) and discuss its potential role in the clinical practice setting. METHOD PubMed and abstracts from the American Society of Clinical Oncology were searched up through September 2015 for clinical data relating to 5-FU TDM. RESULTS 5-FU dosing has been typically determined by using body surface area (BSA). However, it is now well established that BSA-based 5-FU dosing is correlated with a wide variation of 5-FU systemic exposure. Pharmacokinetic (PK) studies of 5-FU systemic exposure have shown a wide range of interpatient variation of 5-FU plasma drug levels. Over the past 30 years, increasing efforts have been placed on optimizing 5-FU dosing with the main goals of increasing antitumor efficacy while reducing drug-associated toxicity. There is growing evidence to show that 5-FU dosing based on plasma 5-FU drug level is feasible and that 5-FU TDM can improve clinical outcomes by improving efficacy of 5-FU-based combination regimens and reducing toxicities. CONCLUSION Dose adjustment of 5-FU is feasible, and PK-based dosing can significantly improve clinical outcomes by reducing toxicities and improving efficacy.

Abstract
INTRODUCTION To investigate the factors that affect the choice of 5-fluorouracil (5-FU) or its oral alternative, capecitabine, as first-line treatment in patients with colorectal cancer (CRC). METHODS Patients treated with 5-FU or capecitabine for CRC between January 1, 2011 and December 31, 2013 in a teaching hospital in the Sydney metropolitan area, Australia were identified using the hospital's database MOSAIQ®. The electronic medical record of each patient was manually reviewed to extract factors potentially affecting treatment choice. Logistic regression was used to assess which patient and/or treatment factors could explain the choice between 5-FU or capecitabine. Where it was available in the medical correspondence, the explicit reason for the choice made was extracted. RESULTS 170 CRC patients were included; 119 on 5-FU, and 51 on capecitabine. The odds of receiving capecitabine as a first-line treatment were positively associated with giving patients a choice in the decision (OR = 17.51, 95% CI: 5.37-57.08). Qualitative data suggest treatment choices were motivated by convenience (oral administration) and tolerability. Time from diagnosis to treatment commencement (OR = 1.02 per month, 95% CI 1.00-1.04) was also found to be positively associated with the choice of capecitabine. The odds of being treated with capecitabine were lower for patients who lived further from the treating hospital (OR = 0.22, 95% CI 0.05-0.94). CONCLUSION This study suggests that patient choice, favoring oral capecitabine over i.v. 5-FU, was a key factor influencing first-line treatment for CRC in this cohort. To respect their autonomy, patients should be involved in the clinical decision making process.

Abstract
Fluoropyrimidines play a central role in the first-line treatment of metastatic colorectal cancer. Our aim was to review whether capecitabine was a safer, non-inferior, economically superior and more convenient alternative to 5-fluorouracil. Capecitabine has previously been compared to 5-fluorouracil-either as a monotherapy or in combination with oxaliplatin, irinotecan, or biological drugs-and has been found to have comparable efficacy and safety profiles. Furthermore, pharmacoeconomic data and patients’ preferences for oral chemotherapy further favor capecitabine. Therefore, capecitabine appears to be an effective and safe alternative to fluorouracil in the first-line treatment of metastatic colorectal cancer.

Abstract
Estimates of the costs associated with cancer care are essential both for assessing burden of disease at the population level and for conducting economic evaluations of interventions to prevent, detect, or treat cancer. Comparisons of cancer costs between health systems and across countries can improve understanding of the economic consequences of different health-care policies and programs. We conducted a structured review of the published literature on colorectal cancer (CRC) costs, including direct medical, direct nonmedical (ie, patient and caregiver time, travel), and productivity losses. We used MEDLINE to identify English language articles published between 2000 and 2010 and found 55 studies. The majority were conducted in the United States (52.7%), followed by France (12.7%), Canada (10.9%), the United Kingdom (9.1%), and other countries (9.1%). Almost 90% of studies estimated direct medical costs, but few studies estimated patient or caregiver time costs or productivity losses associated with CRC. Within a country, we found significant heterogeneity across the studies in populations examined, health-care delivery settings, methods for identifying incident and prevalent patients, types of medical services included, and analyses. Consequently, findings from studies with seemingly the same objective (eg, costs of chemotherapy in year following CRC diagnosis) are difficult to compare. Across countries, aggregate and patient-level estimates vary in so many respects that they are almost impossible to compare. Our findings suggest that valid cost comparisons should be based on studies with explicit standardization of populations, services, measures of costs, and methods with the goal of comparability within or between health systems or countries. Expected increases in CRC prevalence and costs in the future highlight the importance of such studies for informing health-care policy and program planning.

Abstract
A rapidly growing number of oral anticancer agents has become available in oncology and hematology. Though these introductions have several benefits, medication adherence is an issue of concern. Little is known about the factors influencing adherence to treatment with oral anticancer agents in daily practice. Material and methods. In this observational, multicenter study including 216 patients, carried out between October 2010 and March 2012, the use of oral anticancer drugs was assessed by means of a telephonic pill count, a questionnaire and a review of the patient's medical file and pharmacy medication records. Parameters collected were patients' demographics, treatment characteristics, beliefs and attitude towards disease and medicines, self-reported adherence, side effects, quality of life and satisfaction about information. Patients off treatment filled out a questionnaire about the reasons for discontinuation. Optimal adherence was defined as ≥ 95%-≤ 105%. Results. The mean adherence rate (AR) (n = 177) was 99.1% with 20.3% of patients having a sub-optimal AR (< 95%, > 105%) consisting both of under- and over-adherence. Multivariate analyses showed that being on a cyclic dosing regimen (rather than a continuous regimen), not living alone and being highly educated increased the chances of optimal adherence (ORs = 4.88, 4.59 and 2.53, respectively). In addition, optimal adherence was found to be less common in patients reporting treatment control (OR = 0.77). One third of 79 patients off treatment reported their experienced side effects as one of the reasons for discontinuation. Discussion. Although most patients are fully adherent to oral anticancer agents, there is a substantial number tending to non-adherence. Patients living alone and those on a continuous dosing regimen are most likely to adhere sub-optimally. Interventions to improve adherence should specifically address these patients and be tailored to the needs of the individual patient.

Abstract
The objective of this study was to evaluate the real-world cost effectiveness of adjuvant stage III colon cancer chemotherapy regimens, given that previous analyses have been based on data from clinical trials. The study was designed using integrated decision tree and Markov model, which was developed to evaluate the cost effectiveness of 5-fluorouracil/leucovorin (5-FU/LV), capecitabine, and the combination of each with oxaliplatin. The analysis was performed from a US Veterans Affairs perspective via retrospectively collected data, over a 5-year model time horizon. Outcome and cost data were used to calculate cost per quality adjusted life year (QALY), and one-way and probabilistic sensitivity analyses were performed. In the base case analysis, capecitabine and capecitabine plus oxaliplatin both cost more and were less effective than other regimens, and 5-FU/LV plus oxaliplatin, compared to 5-FU/LV alone, resulted in a cost of $25,997 per QALY gained. Model results were generally robust to parameter variation. Capecitabine plus oxaliplatin could be economically reasonable if full dosing occurred ≥76% of the time (base case 42%). In a real-world setting, the addition of oxaliplatin to 5-FU/LV is more effective but also more costly than 5-FU/LV alone. If full dosing of capecitabine-containing regimens can be assured, they may also be cost-effective strategies.

Abstract
BACKGROUND The acquisition costs of biologic drugs are often considered to be relatively high compared with those of nonbiologics. However, the total costs of delivering these drugs also depend on the cost of administration. Ignoring drug administration costs may distort resource allocation decisions because these affect cost effectiveness. OBJECTIVES The objectives of this systematic review were to develop a framework of drug administration costs that considers both the costs of physical administration and the associated proximal costs; and, as a case example, to use this framework to evaluate administration costs for biologics within the UK National Health Service (NHS). METHODS We reviewed literature that reported estimates of administration costs for biologics within the UK NHS to identify how these costs were quantified and to examine how differences in dosage forms and regimens influenced administration costs. The literature reviewed were identified by searching the Centre for Review and Dissemination Databases (DARE, NHS EED and HTA); EMBASE (The Excerpta Medica Database); MEDLINE (using the OVID interface); Econlit (EBSCO); Tufts Medical Center Cost Effectiveness Analysis (CEA) Registry; and Google Scholar. RESULTS We identified 4,344 potentially relevant studies, of which 43 studies were selected for this systematic review. We extracted estimates of the administration costs of biologics from these studies. We found evidence of variation in the way that administration costs were measured, and that this affected the magnitude of costs reported, which could then influence cost effectiveness. CONCLUSIONS Our findings suggested that manufacturers of biologic medicines should pay attention to formulation issues and their impact on administration costs, because these affect the total costs of healthcare delivery and cost effectiveness.

Abstract
BACKGROUND Advances in colorectal cancer (CRC) treatment and improved survival rates have led to higher costs associated with treating CRC. OBJECTIVE To examine health care costs and utilization by initial CRC stage at diagnosis and the number of lines of treatment received by patients with metastatic CRC. METHODS Adult patients with a diagnosis of CRC made from January 1, 2005 to May 31, 2010 were identified from the Oncology Management registry. Patients with stage IV CRC at initial diagnosis or who had advanced to stage IV CRC at the time of the study were included. Registry data included initial CRC stage and the date of diagnosis. Linked health care claims from a large US health insurance database affiliated with Optum were used to identify health care costs and patient characteristics. Multivariate regression analysis was used to estimate total 4-year health care costs stratified by stage and adjusted for patient characteristics. Follow-up ended at patient death, disenrollment from the health care plan, or study end (November 30, 2010). RESULTS A total of 598 patients, followed for an average of 653 days after first evidence of metastasis, were included. At initial diagnosis, 91 patients had stages 0 to III CRC, 310 patients had stage IV CRC, and 197 patients had an unknown stage of CRC. The mean unadjusted total cost per patient (medical + pharmaceutical costs) was $252 200; outpatient hospital visits (excluding radiation and surgery) contributed most to the total cost, at a mean cost of $71 334. Hospitalization costs, with or without surgery (mean, $56 862), accounted for 33% of the $176 135 unadjusted mean cost for medical services (ambulatory visits [office and outpatient], emergency department visits, laboratory/radiology services, and inpatient admission). Chemotherapy and biologics were also costly (mean, $31 112 and $38 276, respectively). A general linear model analysis of estimated 4-year total costs showed that both CRC stage at diagnosis and the number of lines of treatment after metastasis had a statistically significant association with cost (P < 0.001). CONCLUSION Variables that had a statistically significant association with cost (P < 0.05) were sex, age group, and follow-up Charlson Comorbidity Index score after metastases. After adjusting for the number of lines of treatment received, total 4-year costs were highest among patients who presented with stage IV CRC and lowest among patients who presented with stage III CRC and developed metastatic disease.

Abstract
BACKGROUND Capecitabine and cyclophosphamide are active in patients with advanced breast cancer, have non-overlapping toxic effects and synergy pre-clinically. We explored the efficacy and toxic effect of an all-oral combination of capecitabine with cyclophosphamide versus capecitabine alone in a multicentre, randomized, phase II study. PATIENTS AND METHODS Patients with locally advanced or metastatic breast cancer were randomized to treatment with capecitabine given continuously (666 mg/m(2) b.i.d. days 1-28) alone (C) or with oral cyclophosphamide (100 mg/m(2) days 1-14 of a 28-day cycle) (CCy) for up to six cycles. RESULTS Eighty-two patients were randomized. There was no complete response. The proportions with partial response were 36% on C and 44% on CCy, a difference of 7.9% [95% confidence interval (CI) -13.4 to 29.1]. Significant toxic effect was uncommon: grade ≥3 diarrhoea in 4 (10%) versus 1 (3%) patients; grade ≥3 fatigue in 2 (5%) versus 5 patients (13%) and grade ≥2 hand-foot syndrome in 7 (17%) versus 11 (28%) patients receiving C versus CCy, respectively. Median progression-free survival was 3.1 months on C and 6.9 months on CCy, not significantly different statistically. There was no difference in overall survival. CONCLUSION The difference in tumour response suggests a reasonable chance that CCy is superior to C alone.

Abstract
PURPOSE We evaluated the cost-effectiveness of adjuvant chemotherapy using 5-fluorouracil, leucovorin (5FU/LV), and oxaliplatin (FOLFOX) compared with 5FU/LV alone and 5FU/LV compared with observation alone for patients who had resected stage II colon cancer. METHODS We developed 2 Markov models to represent the adjuvant chemotherapy and follow-up periods and a single Markov model to represent the observation group. We used calibration to estimate the transition probabilities among different toxicity levels. The base case considered 60-year-old patients who had undergone an uncomplicated hemicolectomy for stage II colon cancer and were medically fit to receive 6 months of adjuvant chemotherapy. We measured health outcomes in quality-adjusted life-years (QALYs) and estimated costs using 2007 US dollars. RESULTS In the base case, adjuvant chemotherapy of the FOLFOX regimen had an incremental cost-effectiveness ratio (ICER) of $54,359/QALY compared with the 5FU/LV regimen, and the 5FU/LV regimen had an ICER of $14,584/QALY compared with the observation group from the third-party payer perspective. The ICER values were most sensitive to 5-year relapse probability, cost of adjuvant chemotherapy, and the discount rate for the FOLFOX arm, whereas the ICER value of 5FU/LV was most sensitive to the 5-year relapse probability, 5-year survival probability, and the relapse cost. The probabilistic sensitivity analysis indicates that the ICER of 5FU/LV is less than $50,000/QALY with a probability of 99.62%, and the ICER of FOLFOX as compared with 5FU/LV is less than $50,000/QALY and $100,000/QALY with a probability of 44.48% and 97.24%, respectively. CONCLUSION Although adjuvant chemotherapy with 5FU/LV is cost-effective at all ages for patients who have undergone an uncomplicated hemicolectomy for stage II colon cancer, FOLFOX is not likely to be cost-effective as compared with 5FU/LV.

Abstract
Introduction The aim of this study is to evaluate adherence and persistence of patients treated with Imatinib, Nilotinib or Dasatinib, also giving economic evaluations on therapy costs for Received Daily Dose (RDD). Materials and Methods In this retrospective study, we took into account 3 years from 1st Jan. 2009 to 31st March.2012. Treatment adherence was quantified utilizing ratio between RDD and PDD (Prescribed Daily Dose). Persistence is reckoned taking into account the actual therapy days, comparing posology with supplied dose, drawing the graph using Kaplan-Meir method. Results Adherence results in values between 0.8 and 1.0 for Nilotinib (Adh = 0.93), Imatinib (Adh = 0.83) and Dasatinib (0.85). Imatinib has better persistence, 90% of patients in treatment exceed one year of treatment versus 83.3% for Nilotinib and 80% for Dasatinib. The cost per single day of treatment (cost per RDD) was € 39.41 for Imatinib, € 113.60 for Nilotinib and € 94.84 for Dasatinib. Conclusion Patients with CML have a loose of adherence both in first line with Imatinib and in second line of therapy with Dasatinib and Nilotinib. Loss of adherence remains a big problem and could be minimized by a patient-oriented project invlolving physicians, nurses, pharmacists and caregiver.

Abstract
OBJECTIVES Two anti-cancer drugs are currently approved for the treatment of HER2-positive metastatic breast cancer (MBC): trastuzumab-based therapy (TBT) administered intravenously as first line therapy until disease progression and lapatinib, an oral self-administered dual therapy with capecitabine (L+C) as second intention for patients who continue to progress despite TBT. In current practice, TBT is still prescribed beyond disease progression. In addition to medical reasons, the difficulty to switch eligible patients to oral drugs may also be explained by economic reasons. Thus, we aimed at comparing the budgetary impact of TBT and L+C for progressing HER2+MBC after TBT from the French Health Insurance perspective. METHODS A budget impact analysis was performed on a 3-year time horizon (2012-2014) to simulate a dynamic cohort of 4182 HER2-positive patients with a progressing MBC treated with TBT (73%) and L + C (27%). The model was adjusted on progression-free survival (PFS). Office visits, clinical evaluations, drug acquisition, administration costs, and transportation costs obtained from the literature and published databases were considered. RESULTS In the base case analysis (2012), the annual treatment cost per patient for TBT (€36,077) was 2-times higher than that of L + C (€17,165). Using L + C for all patients (n = 4182) would avoid €34.8 million of drug administration and transportation costs. Hospital costs represented 1% vs 88%, while community costs represented 99% vs 12% of L + C and TBT treatment costs, respectively. The lack of direct comparison PFS and treatment dosage modification data were the main limitations. However, no major changes from baseline results were observed from sensitivity analyses. CONCLUSIONS Despite a slightly higher acquisition cost, the treatment cost of L + C remains lower than that of TBT, and it is the only approved anti-HER2 treatment for HER2-positive patients with progressing MBC. Based on this, it seems important to consider the potential savings for Health Insurance with the use of oral drug due to the reduction of outpatient hospitalizations. Such reductions may result in a subsequent budget reduction for hospitals, but may also provide those facing acute medical activity with opportunities to better manage other diseases whose treatment cannot be externalized.

Abstract
Background Mapping patient and work flow and cost analysis studies can help determine the most efficient and cost effective way of providing health services while still maintaining the best standards of care. This study used both time and motion methodology and hospital data to assess the contribution of staff time and facility usage to the overall cost of cancer care during patient visits to a comprehensive cancer centre in Quebec, using metastatic colorectal cancer as a model. Methods A workflow diagram was created mapping direct and indirect steps involved during a patient’s physician or treatment (FOLFOX/bevacizumab or XELOX/bevacizumab) visit. Staff were timed as they performed each task and this data together with compensation amounts were used to calculate personnel costs. Mean work times and 95% confidence intervals (CI) were calculated. Operation and maintenance (O&M) costs for the Centre were calculated using information from hospital databases. All costs were presented in constant Canadian dollars for the 2010–2011 fiscal year period. Results For physician visits, direct and indirect personnel costs were $9.25 (95%CI:$7.00-$11.51) and O&M costs were $60.21, for a total of $69.46 (95%CI:$67.21-$71.72). For treatment visits, personnel and O&M costs were $71.91 (95%CI:$45.53-$98.29) and $62.00 respectively for a total of $133.91 (95%CI:$107.53-$160.29). When calculated for treatment alone, the total cost was $136.06 (95%CI:$109.16-$162.95) for FOLFOX/bevacizumab and $119.94 (95%CI:$96.89-$142.99) for XELOX/bevacizumab. The highest cumulative personnel costs were for the pharmacists and nurses ($38.87 and $34.82 respectively). Regarding patient flow, total time in between steps was 77.6 and 49.5 minutes for a physician or treatment visit respectively. Conclusions This study from a health care provider’s perspective, demonstrated that in the context of increasingly expensive therapies, costs associated with staff time and facility usage do not contribute greatly to the overall cost of treating cancer at this cancer centre. It also illustrated the need for improvements in patient and work flow to reduce wait times in the clinic.

Abstract
BACKGROUND In recent years, patient-reported outcomes such as health-related quality of life have become important areas of clinician focus in general cancer management. Patients' preferences for, and/or satisfaction with, oral versus intravenous (IV) chemotherapy schedules may have a major impact on such outcomes. OBJECTIVE To evaluate preferences for oral or IV chemotherapy in patients with advanced colorectal cancer. METHODS A multicenter, randomized, crossover trial was conducted in 12 hospitals in Southern Italy, in which 22 patients with advanced colorectal cancer received one cycle of oral capecitabine ± irinotecan or oxaliplatin, followed by one cycle of an IV de Gramont or similar regimen (arm A), or the same regimens in reverse order (arm B). Patients were aged 50-70 years and 21% had a higher level of education (graduate or similar). Patients received oral capecitabine 3500 mg/m/day for 7 days (± irinotecan 180 mg/m or oxaliplatin 85 mg/m on day 1 only), followed by an IV de Gramont regimen ± irinotecan (FOLFIRI) or oxaliplatin (FOLFOX); or the two schedules administered in reverse order.The main outcome measure was patients' preferences for oral versus IV chemotherapy, as determined by a pre- and post-treatment therapy preference questionnaire (TPQ). RESULTS Before treatment, 75% of patients preferred oral therapy. Characteristics that patients considered to be important were that treatment should not interfere with daily activities (100% of patients) and should not cause fatigue (95%), diarrhea (76%), or painful mouth ulcers (76%); other factors considered important were the risk of infection and nausea (90%), and that treatment could be administered at home (65%). After receiving both chemotherapy schedules, only 45% of patients preferred oral therapy, while 55% preferred IV therapy. Among the latter, the most important characteristics influencing treatment choice were less nausea (66%), fewer mood effects (65%), the safety of hospital IV treatment (62%), less interference with family relationships (55%), less vomiting (55%), less interference with daily activities (50%), and less diarrhea (50%). Although the order in which patients received therapy did not influence treatment preference, significantly fewer patients with a lower rather than higher educational level preferred oral therapy (47% vs 80%; chi-square test = 9.9; p = 0.002). CONCLUSION These results suggest that there may be a correlation between educational level and the preference of patients with advanced colorectal cancer for oral or IV chemotherapy.

Abstract
INTRODUCTION The role of health-related economy is crucial due to the finite healthcare resources. Intravenous (i.v.) regimes Nordic FLOX and Nordic FLIRI, and the partly oral alternatives XELIRI and XELOX are four commonly used chemotherapies in the first-line treatment of advanced colorectal cancer (CRC) in the Scandinavian countries, all with different costs. AIM To describe and compare costs associated with four commonly used treatments for advanced CRC in clinical routine practice. An additional aim was to evaluate the theoretical cost impact of adverse effects associated with the therapies. MATERIAL AND METHODS The retrospective study was carried out using observations and a clinical quality database of CRC patients treated with Nordic FLOX, Nordic FLIRI, XELIRI and XELOX as first line at an oncology clinic in Gothenburg, Sweden. The treatments are used in parallel in clinical practice. All patients treated from 2003 to 2009 were included. The clinical outcome of the therapies was equivalent; mean treatment time was 5.9-7.7 months. A clinical economic evaluation model was designed. All direct costs associated with the baseline treatment, administration of chemotherapy and drug costs were collected and evaluated. RESULTS The maximum cost for the four treatments was estimated to be 72 000-75 000 SEK per patient for six months, of this approximately 8000 SEK was linked to treatment of toxicity. During six months the i.v. treatments could include 17 more outpatient visits per patient compared to the oral alternatives. During treatment at the clinic around 20% of the patients were hospitalised (XELOX excluded, because of few included patients). CONCLUSION The results indicate that the four regimens are similar in terms of treatment costs. Different costs affect the total cost. The oral alternative makes it possible to treat additional patients with the same labour force resources. Treatment of adverse effects contributes to extensive resource use at the hospital.

Abstract
Adjuvant chemotherapy is the current standard in the management of patients with localised colon cancer (CC) following curative resection. The use of oxaliplatin plus 5 fluorouracil/leucovorin (FOLFOX) or oxaliplatin plus capecitabine-based (XELOX) regimens, both approved in Europe as adjuvant treatment for stage III CC, has improved prognosis in this stage, but questions on their usefulness in high-risk stage II or elderly CC patients and on the role of some prognostic biomarkers are still pending. In April 2010, a consensus meeting on adjuvant CC treatment based on a revision of the most recent literature was held in Spain. The panel considered the use of adjuvant chemotherapy for high-risk stage II CC patients to be justified. Additionally, the more convenient administration of oral fluoropyrimidines vs. IV continuous infusion 5-FU would make XELOX a more suitable alternative for the patient. A more cautious decision should be taken when prescribing oxaliplatin treatment in patients aged ≥70.

Abstract
Huge advances have been made in the treatment of colon cancer over the last decade. Success has been most noticeable in stage IV disease - where careful selection of patients with small-volume disease for treatment with surgical resection ± perioperative chemotherapy has resulted in an improvement in survival of approximately 5-50%; and stage III - disease where the advent of 5-fluorouracil/oxaliplatin, as adjuvant treatment has also resulted in a significant prolongation in survival. Progression-free survival is now an established surrogate for overall survival, and has resulted in more timely reporting of adjuvant studies and therefore faster integration of promising agents into the clinic. Targeted agents, which have shown promise in the metastatic setting, are currently being examined in the adjuvant setting, although results so far are disappointing. Patients with high-risk stage II cancer remain a challenging group. They have a poorer prognosis than those with stage IIIA disease, and national and international guidance recommend offering chemotherapy after careful discussion of the pros and cons. Despite the fact that we have identified many of the biological features that make stage II disease higher risk, we still struggle to achieve the same improvement in survival for this subgroup compared with others. It may be that these patients required treatment with alternative regimens and predictive biomarkers would be particularly helpful.
