Abstract
BACKGROUND Over the past few decades, patient-reported outcomes (PROs) have been used to understand patient health conditions better. Therefore, numerous PRO measures (questionnaires) and guidelines or guidance have been developed. However, it is challenging to select target guidance from among the many available guidance and to understand the chosen guidance. This study comprehensively collected the existing PRO guidance for clinical trials or studies and practices to support novice PRO users in academia, industry, clinical practice, and regulatory and reimbursement decision-making. METHODS For the scoping review, we searched the MEDLINE, Embase, Google Books, WorldCat, and the National Library of Medicine (NLM) Bookshelf databases from 2009 to 2023. The eligibility criteria were PRO guidance for clinical trials, clinical practice, or application such as health technology assessment. Those guidance cover aspects such as quality of life (QOL), PRO, health-related QOL, health state utilities, psychometric requirements, implementation methods, analysis and interpretation, or clinical practice applications. After the systematic search, three researchers individually reviewed the collected data, and the reviewed articles and books were scrutinized using the same criteria. RESULTS We collected the PRO guidance published in articles and books between 2009 and 2023. From the database searches, 1,455 articles and 387 books were identified, of which one book and 33 articles were finally selected. The collected PRO guidance was categorized into the adoption of PRO measures, design and reporting of trials or studies using PROs, implementation of PRO evaluation in clinical trials or studies or clinical practice, analysis and interpretation of PROs, and application of PRO evaluation. Based on this categorization, we suggest the following for novices: When selecting guidance, novices should clarify the "place" and "purpose" where the guidance will be used. Additionally, they should know that the terminology related to PRO and the scope and expectations of PROs vary by "places" and "purposes". CONCLUSIONS From this scoping review of existing PRO guidance, we provided summaries and caveats to assist novices in selecting guidance that fits their purpose and understanding it.

Abstract
OBJECTIVES The purpose of this study is to examine the cost-effectiveness of nivolumab (NIVO) plus ipilimumab (IPI) combination therapy (NIVO + IPI) compared with the sunitinib (SUN) therapy for Japanese patients with advanced renal cell carcinoma from the perspective of a Japanese health insurance payer. METHODS A lifetime horizon was applied, and 2% per annum was set as the discount rate. The threshold was set as $ 75 000 per quality-adjusted life-year (QALY) gained. For the analytical method, we used a partitioned survival analysis model to estimate the incremental cost-effectiveness ratio (ICER), which is calculated by dividing incremental costs by incremental QALYs. Progression-free survival, progressive disease, and death were set as health states. Additionally, cost parameters and utility weights were set as key parameters. We set the intermediate/poor-risk population as the base case. Scenario analysis was conducted for the intention-to-treat population and the favorable risk population. Furthermore, one-way sensitivity analysis and probabilistic sensitivity analysis were conducted for each population. RESULTS In the base-case analysis, the QALYs of NIVO + IPI and SUN were 4.32 and 2.99, respectively. NIVO + IPI conferred 1.34 additional QALYs. Meanwhile, the total costs in the NIVO + IPI and SUN were $692 288 and $475 481, respectively. As a result, the ICER of NIVO + IPI compared with SUN was estimated to be $162 243 per QALY gained. The parameter that greatly affected the ICER was the utility weight of progression-free survival in NIVO + IPI. CONCLUSIONS NIVO + IPI for advanced renal cell carcinoma seems to be not cost-effective compared with the SUN in the Japanese healthcare system.

Abstract
Patient-reported outcomes (PROs) are frequently used in a variety of settings, including clinical trials and clinical practice. The definition of PRO and quality of life (QOL) and their relationship have been concluded through discussions among experts that has been the premise of PRO guidelines are not clearly stated in the guidelines. Therefore, the definition of PRO, especially in relation to QOL, is sometimes explained simply, as "PRO includes QOL," but this complicated matters. This study investigated the perceptions of PRO among various stakeholders (including patients and their families, the industry, clinicians, regulatory or health technology assessment personnel, and academic researchers) in Japan to clarify its definitions and that of QOL, including their relationship.We conducted a two-step survey: a qualitative interview survey and a web-based survey to ensure the validity of the survey. During the interviews, eight stakeholders described their perceptions and thoughts on PRO and its relationship to QOL, and their experience of using PRO. Overall 253 clinicians, 249 company employees, and 494 patients participated in the web survey to confirm how the findings of the interview survey supported the results.In the interview survey, patient advocates described various perspectives of PRO and QOL, including unexpected dynamic relationships, while the most other stakeholders explained PRO and QOL with the language used in the guidelines, but their responses were split. The web-based survey revealed that all stakeholders had a lower awareness of PRO than QOL. The most common perception of PRO, especially in the relationship to QOL, was "they did not fully overlap." Although there were differences in perceptions of the relationship between PRO and QOL among clinicians, company employees, and patients, all perceived PRO as a tool to facilitate communication in clinical practice.The present results are inconsistent with the simplified explanation of PRO, but consistent with the original PRO guideline definitions, which also considered the role of PRO in clinical practice. To make PRO a more potent tool, all stakeholders using PRO should confirm its definition and how it differs from QOL, have a unified recognition in each PRO use, and avoid miscommunication.

Abstract
BACKGROUND This study aimed to evaluate the cost-effectiveness of nivolumab plus chemotherapy (NIVO + Chemo) compared with chemotherapy monotherapy (Chemo) for patients with advanced or metastatic HER2-negative gastric or gastroesophageal junction or esophageal adenocarcinoma (GC/GEJC/EAC) in Japan from the perspective of healthcare payer. METHODS A partitioned survival analysis model was developed to predict costs and quality-adjusted life years (QALYs) for NIVO + Chemo and Chemo. The time horizon of the model was set to 38 years. An annual discount rate of 2% for both costs and QALYs was applied. Data on overall survival and progression-free survival were derived from the CheckMate649 trial. Cost parameters were estimated from a Japanese medical claims database. The incremental cost-effectiveness ratio (ICER) of NIVO + Chemo compared with Chemo was estimated. A subgroup analysis on the level of PD-L1 CPS expression was conducted. In addition, sensitivity analysis was performed to assess the uncertainty in the parameter settings. RESULTS The incremental cost and QALY of NIVO + Chemo compared with Chemo were USD99,416 and 0.30 QALY, respectively. The ICER of NIVO + Chemo was estimated to be USD327,161 per QALY gained. The results of the subgroup analysis showed that ICER was USD247,403/QALY and USD302,183/QALY for PD-L1 CPS ≧ 5 and ≧ 1, respectively. Sensitivity analyses showed a relatively robust result that the ICER remained higher than the Japanese cancer threshold of USD75,000-150,000/QALY. CONCLUSIONS Applying the Japanese cancer threshold of USD75,000-150,000/QALY, NIVO + Chemo was not cost-effective for patients with advanced or metastatic HER2-negative GC/GEJC/EAC in Japan from the perspective of healthcare payer.

Abstract
Abstract
Background Eribulin is a chemotherapeutic drug that prolongs overall survival (OS) in patients with HER2-negative metastatic breast cancer (MBC), mainly in third-line or later chemotherapy (ChT) [1]. However, health-related quality of life (HRQOL) and efficacy in patients who receive eribulin as first- or second-line therapy is not well known. In contrast, S-1, an oral 5-fluorouracil derivative, shows similar OS to taxanes as first-line ChT and better HRQOL, based on a large phase III trial conducted in Japan [2]. Here, we compared the effect on HRQOL and efficacy of eribulin and S-1 in MBC patients in a first- or second-line ChT setting. Methods We planned an open-label, multicenter, randomized controlled phase III study at 50 hospitals in Japan. We enrolled patients with HER2-negative MBC who had no or one previous ChT for MBC regardless of prior administration of anthracyclines and taxanes. Patients were randomly assigned (1:1) to either eribulin (1.4 mg/m² administered on days 1 and 8 of a 21-day) or S-1 (40–60 mg twice daily for 14 consecutive days, followed by a 7-day break). Randomization was stratified by institution, age, treatment line, hormone receptor status, and time from surgery to recurrence. HRQOL assessment was conducted using the European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire-Core 30 questions (QLQ-C30) every six weeks until week 24, and then every nine weeks until week 42 after baseline assessment. The primary outcome measure was the global health status (GHS) score of EORTC QLQ-C30, with a prespecified non-inferiority margin of 10% for a difference in the proportion of patients experiencing deterioration at one year. Clinically meaningful deterioration was defined as a ≥ 10-point decrease from baseline GHS score or death. Secondary outcomes were OS, progression-free survival (PFS), and adverse events. We estimated that the study needed 330 patients to obtain 80% power for non-inferiority. This trial was registered with the University Hospital Medical Information Network, Japan (protocol ID 000021398). Results Between June 2016 and October 2019, 302 patients were enrolled, with 152 assigned to eribulin and 148 to S-1. The full analysis set for HRQOL assessment included 134 and 136 patients, while that for efficacy consisted of 141 and 144 patients, respectively. Overall compliance with the questionnaire was 85.6 %. Among the full analysis set for efficacy, 28 (19.9%) and 31 (21.5%) cases were triple negative, respectively. Eribulin and S-1 were administered as first-line ChT in 99 (70.2%) and 101 (70.1%) patients, respectively. Risk difference of GHS deterioration through one year for the eribulin versus S1 group was -0.66% (95% CI -12.47 to 11.16; P non-inferiority =0.077). Median time to first deterioration in GHS score was 5.64 months (95% CI 3.51–8.00) and 5.28 months (95% CI 3.28-7.80) (HR 1.07 [95% CI 0.79–1.45]; P =0.667); median OS was 35.0 months (95% CI 27.2-41.0) and 27.8 months (95% CI 24.6-33.5) (HR 0.69 [95% CI 0.50-0.95]; P=0.023); and median PFS was 6.07 months (95% CI 5.48-7.80) and 6.66 months (95% CI 5.48-7.77), respectively (HR 0.90 [95% CI 0.68-1.18]; P=0.427). No previously unrecognized adverse events were observed. Conclusions We found a marginal non-inferiority in HRQOL for eribulin, albeit that the difference was not statistically significant owing to the smaller than planned sample size. Time to first clinically meaningful deterioration was almost identical between the two arms, whereas OS was significantly extended with eribulin. These findings indicate that eribulin in first- or second-line ChT is acceptable as a standard regimen in this patient population. [1] Lancet 2011; 377: 914–23 [2] Lancet Oncol 2016; 17: 90–98

Abstract
OBJECTIVE To evaluate the cost-effectiveness of universal newborn screening using stool color card or direct bilirubin (DB) testing when comparing with no screening for biliary atresia in Japanese setting. STUDY DESIGN A decision analytic Markov microsimulation model was developed to evaluate the universal screening for biliary atresia. Our screening strategies included stool color card, DB, or no screening. The outcomes of all newborns undergoing 3 strategies were simulated to analyze event-free life-years defined as liver transplant-free survival, costs, and incremental cost-effectiveness ratio (ICER) over a 25-year period with an annual discount rate of 2% applied for both costs and outcomes. A 1-way sensitivity analysis was performed to assess the uncertainty. RESULTS There were 941 000 newborn infants in our cohort and 114 cases of biliary atresia. The base case analysis showed that the stool color card strategy was $14 927 337 higher than no screening with an increase in 44 more event-free life-years gained, resulting in an ICER of $339 258 per event-free life-year gained. The DB screening strategy compared with stool color card was $138 994 060 higher with an increase in 271 more event-free life-years gained and an ICER of $512 893 per event-free life-year gained. The DB screening strategy compared with no screening resulted in an ICER of $488 639 per event-free life-year gained. The DB screening resulted in 16 fewer liver transplants than stool color card and stool color card had 2 fewer liver transplants than no screening. CONCLUSIONS Universal screening for biliary atresia could be cost-effective depending on the willingness to pay thresholds for health benefits.

Abstract
OBJECTIVES This study aimed to develop direct and response mapping algorithms from the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 onto the 5-level version of EQ-5D index based on the gradient boosted tree (GBT), a promising modern machine learning method. METHODS We used the Quality of Life Mapping Algorithm for Cancer study data (903 observations from 903 patients) for training GBTs and testing their predictive performance. In the Quality of Life Mapping Algorithm for Cancer study, patients with advanced solid tumor were enrolled, and the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 and 5-level version of EQ-5D were simultaneously evaluated. The Japanese value set was used for direct mapping, whereas the Japanese and US value sets were used for response mapping. We trained the GBTs in the training data set (80%) with cross-validation and tested the predictive performance measured by the root mean squared error (RMSE), mean absolute error (MAE), and mean error in the test data set (20%). RESULTS The RMSE and MAE in the test data set were larger in the GBT approaches than in the previously developed regression-based approaches. The mean error in the test data set tended to be smaller in the GBT approaches than in the previously developed regression-based approaches. CONCLUSIONS The predictive performances in the RMSE and MAE did not improve by the GBT approaches compared with regression approaches. The flexibility of the GBT approaches had the potential to reduce overprediction and underprediction in poor and good health, respectively. Further research is needed to establish the role of machine learning methods in mapping a nonpreference-based measure onto health utility.

Abstract
BACKGROUND In clinical studies, the EQ-5D-5L is often employed with disease-specific health-related quality of life instruments. The questions in the former are more general than the latter; however, it is known that responses to general questions can be influenced by preceding specific questions. Thus, the responses to the EQ-5D-5L have the possibility of being influenced by the preceding disease-specific health-related quality of life instruments. This may lead to bias in the cost-effectiveness analysis results. Therefore, this study aimed to evaluate the impact of the preceding cancer-specific health-related quality of life instruments on the EQ-5D-5L responses. METHODS We prepared questionnaire booklets containing the EQ-5D-5L, the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30, and the Functional Assessment of Cancer Therapy General with different orders. Using a quasi-randomized design, they were distributed to the patients undergoing drug therapy for advanced cancer, who were classified into three groups: Groups 1, 2, and 3 (the EQ-5D-5L placed first, second, and last, respectively). We compared the EQ-5D-5L index and the missingness of EQ-5D-5L among the groups. RESULTS The mean EQ-5D-5L index was 0.796, 0.760, and 0.789 for groups 1 (n = 300), 2 (n = 306), and 3 (n = 331), respectively. The difference between Groups 2 and 1 was - 0.036 (95% CI - 0.065 to - 0.007; p = 0.015). The proportion of patients with an incomplete EQ-5D-5L was 0.11, 0.11, and 0.05 for Groups 1, 2, and 3, respectively. The difference of the proportions between group 3 and 1 and between 3 and 2 was - 0.06 (95% CI - 0.10 to - 0.02; p = 0.003) and - 0.06 (95% CI - 0.10 to - 0.02; p = 0.003), respectively. CONCLUSIONS Although the EQ-5D-5L index differed according to the instrument orders, the difference size would not be considerably larger than the minimally important difference. The patients tended to complete the EQ-5D-5L when they were placed at the end of the questionnaire.

Abstract
Background and Objective Trastuzumab is a standard care as adjuvant chemotherapy (AdjCT) for patients with human epidermal growth factor receptor 2 (HER2)-positive primary breast cancer (BC) in Japan. However, no reports have evaluated its economics for patients with HER2-positive BC over 70 years of age. The objective of this study was to evaluate the cost-effectiveness of HER2-targeted trastuzumab + chemotherapy in Japan, comparing it with trastuzumab monotherapy. Methods A three-state-partitioned survival model was developed to evaluate the cost-effectiveness of trastuzumab + chemotherapy versus trastuzumab monotherapy for AdjCT in elderly patients with HER2-positive BC. We derived the efficacy data, utilities, and costs of both arms from individual patient data in the RESPECT trial (NCT01104935) and published studies. The costs and quality-adjusted life years (QALYs) were discounted at 2% per annum using a payer perspective. The respective cost estimates were reported in 2019 Japanese Yen (JPY) or US dollars (US$). The primary outcome was the incremental cost-effectiveness ratio (ICER). We assured robustness with deterministic and probabilistic sensitivity analyses. Results The cost per patient for trastuzumab + chemotherapy was JPY 14.6 million (US$137,000), and their QALYs were 9.308, compared with JPY 14.2 million (US$131,000) and 9.101, respectively, for trastuzumab monotherapy. The ICER of trastuzumab + chemotherapy versus trastuzumab monotherapy was JPY 2.7 milllion/QALY (US$17,200/QALY). The ICER for trastuzumab with chemotherapy varied from "Dominant" to "Dominated" in one-way sensitivity analysis. Conclusions The base-case analysis suggests that AdjCT with trastuzumab + chemotherapy is likely to be a cost-effective choice for patients with HER2-positive BC aged 70 years or older. However, the sensitivity analysis suggested uncertainty regarding the cost-effectiveness of trastuzumab + chemotherapy.

Abstract
OBJECTIVE The purpose of this analysis was to evaluate the cost effectiveness of the combination of pertuzumab, trastuzumab, and docetaxel (PTD) for the treatment of patients with human epidermal growth factor receptor-2 (HER2)-positive breast cancer in Japan. METHODS A partitioned survival analysis model was developed to predict costs and quality-adjusted life-years (QALYs) in a PTD arm and a trastuzumab plus docetaxel (TD) arm. Direct medical costs were considered from the perspective of the Japanese healthcare system. The time horizon of the model was set to 20 years. Data on overall survival and progression-free survival were derived from the CLEOPATRA trial. Cost parameters were estimated using a real-world claims database. Utilities were derived from published sources outside Japan. The incremental cost-effectiveness ratio (ICER) of PTD therapy compared with TD therapy was estimated. Sensitivity analysis was conducted to assess the uncertainty in parameter settings. RESULTS Compared with TD therapy, PTD therapy incurred an additional cost of $US174,479 and conferred an additional 0.949 QALYs. This resulted in an ICER of $US183,901 per QALY gained. Utility weights for progression-free survival and progressed disease had a relatively large impact on the base-case result, but the ICERs remained higher than $US75,000 per QALY over the full range of model parameters. Based on a probabilistic sensitivity analysis, the probability that PTD is cost effective was estimated to be 3.3%. CONCLUSIONS Applying a willingness-to-pay threshold of $US75,000 per QALY, PTD therapy as first-line therapy would not be cost effective. Further research is required on utilities and clinical benefits for Japanese patients with breast cancer.

Abstract
PURPOSE To investigate whether postoperative adjuvant trastuzumab plus chemotherapy negatively affected cognitive functioning during the post-chemotherapy period compared with trastuzumab monotherapy in older patients with HER2-positive breast cancer. METHODS In the randomized RESPECT trial, women aged between 70 and 80 years with HER2-positive, stage I to IIIA invasive breast cancer who underwent curative operation were randomly assigned to receive either 1-year trastuzumab monotherapy or 1-year trastuzumab plus chemotherapy. Cognitive functioning was assessed using the Mini-Mental State Examination (MMSE) test at enrollment and 1 and 3 years after initiation of the protocol treatment. The primary outcome was change in the MMSE total score from baseline. Secondary outcomes included prevalence of suspected mild cognitive impairment (MMSE total score < 28) and suspected dementia (MMSE total score < 24). RESULTS The analytical population consisted of 29 and 26 patients in the trastuzumab monotherapy and trastuzumab plus chemotherapy groups, respectively. The group differences in mean changes of the MMSE total score were 0.6 (95% confidence interval [CI] - 0.3 to 1.6) at 1 year and 0.9 (95% CI - 1.0 to 2.8) at 3 years (P = 0.136 for the group difference pooling the two visits). The prevalence of suspected mild cognitive impairment at 3 years was 41.7% in the trastuzumab monotherapy group and 28.6% in the trastuzumab plus chemotherapy group (P = 0.548). CONCLUSION This randomized sub-study did not show worse cognitive functioning during the post-chemotherapy period with trastuzumab plus chemotherapy than with trastuzumab monotherapy in older patients with HER2-positive breast cancer. TRIAL REGISTRATION NUMBER NCT01104935 (first posted April 16, 2010).

Abstract
PURPOSE This study aimed to determine whether continual electronic patient-reported outcome (ePRO) measurements at home can capture the fluctuations in health-related quality of life (HRQOL) scores between visits. METHODS We performed a randomized controlled trial to compare the scores obtained by standard practice (paper-based measurements in the hospital) to scores by continuous measurement of ePRO at home. Metastatic cancer patients were randomly assigned to either the paper-based (n = 50) or the ePRO group (n = 52). EQ-5D-5L and EORTC QLQ C-30 scores were obtained on 3 different chemotherapy days in the paper-based group. Meanwhile, scores were obtained on the chemotherapy day and on days 3, 7, 10, and 14 in the ePRO group during 2 cycles. The first hypothesis of our study was that both scores at the same time points would be equivalent despite different measurement frequency, place, or mode of measurement. The second hypothesis was that PRO score-adjusted time would be different between the groups. For equivalence, the endpoint was the mean EQ-5D-5L index value on the chemotherapy day before the outpatient treatment. Only if equivalence was shown, quality-adjusted life-days (QALDs) were considered using all the data. RESULTS The adjusted mean difference in the EQ-5D-5L index was determined to be -0.013 (95% confidence interval [CI]: -0.049 to 0.022); the 95% CI did not exceed the equivalence margin. Similarly, the mean difference in global health status (2.28 [95% CI: -2.55 to 7.11]) also showed equivalence. However, the QALD by EQ-5D-5L was significantly lower in the ePRO group by 1.36 per 30 d (95% CI: -2.22 to -0.51; P = 0.0021). CONCLUSIONS Continual measurements of the HRQOL at home by ePRO may yield more detailed profiles of the HRQOL.

Abstract
Background To develop direct and indirect (response) mapping algorithms from the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) and the Functional Assessment of Cancer Therapy General (FACT-G) onto the EQ-5D-5L index. Methods We conducted the QOL-MAC study where EQ-5D-5L, EORTC QLQ-C30, and FACT-G were cross-sectionally evaluated in patients receiving drug treatment for solid tumors in Japan. We developed direct and indirect mapping algorithms using 7 regression methods. Direct mapping was based on the Japanese value set. We evaluated the predictive performances based on root mean squared error (RMSE), mean absolute error, and correlation between the observed and predicted EQ-5D-5L indexes. Results Based on data from 903 and 908 patients for EORTC QLQ-C30 and FACT-G, respectively, we recommend two-part beta regression for direct mapping and ordinal logistic regression for indirect mapping for both EORTC QLQ-C30 and FACT-G. Cross-validated RMSE were 0.101 in the two methods for EORTC QLQ-C30, whereas they were 0.121 in two-part beta regression and 0.120 in ordinal logistic regression for FACT-G. The mean EQ-5D-5L index and cumulative distribution function simulated from the recommended mapping algorithms generally matched with the observed ones except for very good health (both source measures) and poor health (only FACT-G). Conclusions The developed mapping algorithms can be used to generate the EQ-5D-5L index from EORTC QLQ-C30 or FACT-G in cost-effectiveness analyses, whose predictive performance would be similar to or better than those of previous algorithms.

Abstract
OBJECTIVE We investigated the quantification of the response shift-adjusted treatment effect on quality-of-life (QOL) data in a randomized controlled trial of taxane versus S-1 for patients with metastatic breast cancer (SELECT-BC). METHODS This study was a secondary data analysis of a previously published trial. The response shift-adjusted treatment effect on health-related QOL (HRQOL) data measured by the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) was estimated using structural equation modeling techniques in addition to quantifying the "true" treatment effect. Measurement invariances in the values of the common factor loadings, intercepts, and residual variances between before treatment and at the 3-, 6-, and 12-month visits were considered the response shift effects. RESULTS In the taxane group, we observed positive recalibration effects for role functioning and positive reprioritization and negative recalibration effects for emotional functioning. The observed change of -4.56 for role functioning comprised +2.26 response shifts and -6.82 "true" change. The observed change of +9.41 for emotional functioning comprised +12.43 response shifts and -1.17 "true" change. In the S-1 group, we observed positive reprioritization and negative recalibration effects for emotional functioning and positive reprioritization effects for social functioning. The observed change of +10.54 for emotional functioning comprised +10.07 response shifts and +0.47 "true" change. The observed change of +2.43 for social functioning comprised +3.50 response shifts and -1.07 "true" change. CONCLUSION Detailed analysis of the response shift effects will improve the evaluation reliability of observed HRQOL data during clinical trials.

Abstract
Purpose This study aimed to assess psychometric properties of the Japanese version of the EQ-5D-Y (3 levels) with a focus on feasibility, reliability, and construct validity. Methods Respondents were recruited from the general populations of three cities in Japan. First, children and adolescents responded to the EQ-5D-Y and PedsQL by self-report. Parents were also asked to evaluate the health states of their children/adolescents using proxy versions of these questionnaires. Next, the EQ-5D-Y was mailed to their residence approximately 2 weeks later, and both children/adolescents and their parents responded to the questionnaire. Reliability was confirmed by self-report test–retest methods and a comparison of self-report responses with proxy responses. Spearman’s correlation coefficients were calculated between responses to the EQ-5D-Y and both responses to and scores of the PedsQL in order to assess construct validity. Results A total of 654 children/adolescents from aged 8 to 15 (median age: 11) responded to the questionnaires at both the first- and second-stage surveys. Test–retest agreement was sufficiently high and was influenced by age. Proxy test–retest results revealed that parents’ responses were more reliable compared to the self-report results. Some correlations (|r| > 0.3) between items of the EQ-5D-Y and PedsQL were found. Meanwhile, no correlations were found between proxy responses to the EQ-5D-Y and self-report responses to the PedsQL. Conclusions The EQ-5D-Y demonstrates reliability and validity among children/adolescents and their parents in Japan. Construct validity of the EQ-5D-Y by self-report was confirmed through comparisons with the PedsQL. Proxy responses to the EQ-5D-Y were more reliable compared to the self-report results, but construct validity was not confirmed in the proxy version.

Abstract
PURPOSE To obtain health utility data to allow for cost-effectiveness analysis in groups stratified by disease progression along with health-related quality of life (HRQoL) information in Japanese prostate cancer (PC) patients. METHODS In this cross-sectional observational study, EuroQol-5 Dimension- 5 Level (EQ-5D-5L), EuroQol Visual Analog Scale (EQ-VAS), and Functional Assessment of Cancer Therapy-Prostate (FACT-P) measures were used to examine utility, VAS scores, and disease-specific HRQoL, respectively. Scores obtained were statistically examined for the correlation among measures and domains. Parameter estimates of statistically significant factors were assessed using generalized linear models (GLM). RESULTS A total of 380 patients stratified by their disease progression status were analyzed. The numbers (%) of patients in groups stratified as having localized (L), localized progression (LP), distant metastatic (DM), and DM-castration-resistant PC (CRPC) were 275 (72.4), 40 (10.5), 27 (7.1), and 38 (10.0), respectively. EQ-5D-5L mean (standard deviation, SD) scores of L, LP, DM, and DM-CRPC in study participants were 0.87 (0.15), 0.86 (0.15), 0.85 (0.18), and 0.84 (0.17), respectively. The mean (SD) scores assessed by EQ-5D-5L, EQ-VAS, and FACT-P instruments were 0.86 (0.16), 74.6 (16.8), and 110.8 (19.6), respectively. Utility scores correlated well with FACT-P scores. Eastern Cooperative Oncology Group performance status had significant influences on all instruments' scores. CONCLUSIONS We obtained health utility and HRQoL scores of Japanese PC patients stratified by disease progression in detail. Our results will be useful for establishing cost-effectiveness analyses in Japanese PC settings.

Abstract
Abstract
OBJECTIVE: The RESPECT trial compared 1-year trastuzumab monotherapy with trastuzumab plus standard chemotherapy as a postoperative adjuvant therapy in HER2-positive elderly breast cancer patients. Primary objective of this study was to verify the noninferiority of 1-year trastuzumab monotherapy to trastuzumab plus chemotherapy in terms of disease free survival, and the planned analysis showed that the difference of restricted mean survival time between two groups at 3 years was 0.45 months (reported by Sawaki at ASCO2018). This report assesses the patients-reported outcomes and health-related quality of life (HRQoL).
PATIENTS AND METHODS: The study was done at 99 hospitals in Japan. Elderly women (70 to 80 years old) with HER2-positive, stageI-IIIA invasive breast cancer treated by surgery with clear resection margins were randomly assigned to receive either 1-year trastuzumab or 1-year trastuzumab plus standard chemotherapy, stratified by age, hormone-receptor status, pathological lymph node metastasis and institution. Patients completed questionnaires at baseline, 2 months, 1year, and 3 years after protocol treatment started. The primary outcome was global HRQoL assessed using Functional Assessment of Cancer Therapy-General (FACT-G) total score, and secondary outcomes were chemotherapy-induced peripheral neuropathy (CIPN), instrumental activities of daily living (IADL), anxiety, depression, and subjective happiness. We did the analyses by intention to treat, including patients who completed questionnaires at baseline before start of protocol treatment, and 5point or more change is meaningful in FACT-G total score. This study is registered with ClinicalTrials.gov, NCT01104935.
RESULTS: Between Oct 2009 and Oct 2014, 275 patients were enrolled in the study, of whom 9 patients were excluded: 135 assigned to trastuzumab monotherapy and 131 assigned to trastuzumab plus chemotherapy. We detected significant difference between treatment groups for: clinically meaningful HRQoL deterioration rate at 2 months (31% for trastuzumab monotherapy vs 48% for trastuzumab plus chemotherapy; p=0.016) and at 1year (19% vs 38%; p=0.009), clinically meaningful HRQoL improvement rate at 2 months (38% for trastuzumab monotherapy vs 15% for trastuzumab plus chemotherapy; p<0.01) and at 1year (43% vs 25%; p=0.021), severe sensory CIPN rate at 2months (1.9% for trastuzumab monotherapy vs 14.4% for trastuzumab plus chemotherapy; p=0.001), IADL score at 1year (11.97 for trastuzumab monotherapy vs 11.54 for trastuzumab plus chemotherapy; p<0.042), Hospital Anxiety and Depression Scale score at 2months (8.92 for trastuzumab monotherapy vs 10.79 for trastuzumab plus chemotherapy; p<0.003), and subjective happiness score at 1year (12.8 for trastuzumab monotherapy vs 11.8 for trastuzumab plus chemotherapy; p<0.024).
CONCLUSION: Given the small advantage of adjuvant trastuzumab plus chemotherapy compared to trastuzumab monotherapy for elderly HER-2 positive breast cancer women, decisions about treatment should be informed by the risk for adverse health effects associated with chemotherapy.

Abstract
Abstract
OBJECTIVE: The effect of trastuzumab(Tmab) or chemotherapy on cognitive function has not been fully understood, especially in elderly breast cancer patients. The RESPECT trial compared 1-year(yr) Tmab monotherapy with Tmab plus standard chemotherapy as adjuvant therapy in elderly patients with HER2-positive breast cancer. The primary objective was to verify the noninferiority of 1-yr Tmab monotherapy compared to Tmab plus chemotherapy in terms of disease-free survival, and the planned analysis showed that the difference of restricted mean survival time between two groups at 3 yrs was 0.45 months (Sawaki at ASCO2018). The goal of this report was to assess the impact of the treatment groups on longitudinal cognitive function.
PATIENTS AND METHODS: The study was performed with patients from 99 hospitals in Japan. Elderly women with HER2-positive, stage I-IIIA invasive breast cancer surgery treated with clear resection margins were randomly assigned to either receive 1-yr Tmab or 1-yr Tmab plus standard chemotherapy. 15 institutions participated in the cognitive sub-study. Cognitive function was assessed using the Mini-Mental State Examination (MMSE) at baseline and at 1 and 3 yrs after treatment. The primary outcome was the amount of change in the MMSE score from the baseline. A linear mixed-effects model was used for comparisons of change in the MMSE score between groups, controlling for time and baseline score. Secondary outcomes were the proportion of both suspected mild dementia (MMSE≤27) and dementia (MMSE≤23) at each time point.
RESULTS: Between October 2009 and October 2014, 275 patients were enrolled in the RESPECT trial, and 57 patients were enrolled in the cognitive function sub-study with 2 patients subsequently excluded. The 55-patient sub-study comprised 29 patients assigned to the Tmab monotherapy group and 26 patients assigned to the Tmab plus chemotherapy group. Primary analysis revealed that change in the MMSE score was not significantly different between the two groups (difference −0.6 at 1 yr and −0.9 at 3 yrs; p=0.136), whereas the baseline score was the only significant factor that had an effect on the amount of change in the MMSE score (p<0.001). The proportions of suspected mild dementia at baseline, and at 1 yr and 3 yrs were 15.4, 32.0, and 41.7% in the Tmab monotherapy group, and 45.8, 17.6, and 28.6% in the Tmab plus chemotherapy group. The proportions of suspected mild dementia at baseline were significantly higher in the Tmab plus chemotherapy group (p=0.04). The proportions of suspected dementia at baseline, and at 1 yr and 3 yrs were 0%, 0%, and 4.2% in the Tmab monotherapy group, and 4.2%, 0%, and 4.8% in the Tmab plus chemotherapy group. There were no significant differences in the proportions of suspected dementia between the treatment groups at each time point.
CONCLUSION: Postoperative chemotherapy for elderly breast cancer patients was considered to have little effect on the onset of dementia during the follow-up period of 3 yrs. Further long-term observation is necessary to obtain a significant conclusion.

Abstract
Abstract
Background: Chemotherapy-induced peripheral neuropathy (CIPN) is a frequent side-effect of taxanes which play a central role in the treatment of breast cancer. CIPN can negatively influence long-term quality of life, warranting the development of effective prevention strategies. This study investigates the efficacy of frozen gloves and socks (FGS) in reducing the incidence and severity of nab-paclitaxel-induced peripheral neuropathy. Endpoints were evaluated using both clinician and patient reports.
Methods: This is a multicenter phase II single arm trial study of the effects of FGS for advanced or metastatic breast cancer patients receiving nab-paclitaxel (260 mg/m2) every 3 weeks. Patients wore FGS on their diseased side hand and foot for 60 min during infusion. The other side acted as the untreated control. CIPN was assessed using Patient Neurotoxicity Questionnaire (PNQ), PRO-CTCAE and CTCAE at baseline and every cycle of nab-paclitaxel. The primary endpoint was the incidence of CIPN assessed by PNQ (grade C or higher) after receipt of up to 4 cycles of nab-paclitaxel.
Results: Between September 2012 and January 2015, 50 patients from 16 sites were enrolled in this study. Of 50 patients, 27 (54%) received at least 4 cycles of nab-paclitaxel. There was a trend for the incidence of CIPN assessed by PNQ and PRO-CTCAE to be lower in the intervention side than in the control side, although this difference was not statistically significant. The incidence of CIPN assessed by CTCAE was significantly lower in the treated hand (Table).
Conclusions: Among breast cancer patients who received nab-paclitaxel, FGS produced favorable effects as detected by reduced clinician-reported CTCAE grades for CIPN, although the study did not detect differences in self-reported symptoms of CIPN using PRO-CTCAE or PNQ. Clinical trial information: UMIN000007907.

Abstract
OBJECTIVES Myelofibrosis (MF) is associated with a significant symptom burden that severely impacts patient quality-of-life (QoL). Ruxolitinib, a potent Janus kinase 1 (JAK1)/JAK2 inhibitor, led to substantial improvements in splenomegaly, MF-associated symptoms, and QoL in the phase 3 COMFORT studies, proving superior to placebo and best available therapy. This study evaluated the effect of ruxolitinib on symptoms and QoL in Japanese patients with MF. METHODS A pooled analysis of studies A2202 (NCT01392443) and AJP01 (NCT02087059) of ruxolitinib in Japanese patients with MF (n = 81) was conducted. Changes in total symptom score (TSS) and the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 were summarized. RESULTS Most patients received a starting dose of 15 or 20 mg twice daily (BID) and had a final titrated dose of ≥10 mg BID. Overall, 67.7% (44/65) achieved a ≥50% reduction from baseline in TSS at week 24. Reductions in TSS were seen in every dose group; the greatest reductions occurred in patients with a final titrated dose of 20 or 25 mg BID. Improvements in QoL were seen in patients who achieved a ≥50% reduction in TSS. Generally, improvements in TSS and individual symptoms correlated with reductions in spleen size, with those having a ≥35% reduction in spleen volume having the greatest improvements. CONCLUSIONS Consistent with COMFORT-I, ruxolitinib provided substantial improvements in symptoms and QoL in Japanese patients with MF, with higher doses of ruxolitinib associated with better responses.

Abstract
OBJECTIVE The aim of this study was to investigate the impact of adverse events (AEs) on health utility and health-related quality of life (HRQOL) in patients with metastatic breast cancer undergoing first-line chemotherapy. METHODS We analyzed the data from the SELECT BC study, a multicenter, open-label, randomized, phase III study conducted in Japan, which compared first-line S-1 with taxane therapies. Heath utility and HRQOL were assessed using the EQ-5D-3L and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) at baseline and 3, 6, and 12 months after treatment initiation. Health utility was calculated based on societal preferences, and AEs were reported at each cycle of the study treatment. Linear marginal mean models were used to quantify the impact of the last AEs (with 10 or more incidences) observed before HRQOL assessment on health utility and HRQOL. RESULTS Analysis included 380 patients and 12 (of 15) AEs. Grade 1 nausea and oral mucositis, grade 1 and 2 edema, and grade 2 fatigue, motor and sensory neuropathy, and myalgia were significantly associated with disutility, measured using the EQ-5D-3L. Grade 1 oral mucositis, grade 1 and 2 fatigue, and grade 2 sensory neuropathy were significantly associated with impaired global health status in the EORTC QLQ-C30. AEs associated with decrements in the five functioning scales included fatigue, oral mucositis, nausea, edema, motor and sensory neuropathy, and myalgia. CONCLUSIONS We reported disutilities caused by AEs in patients with metastatic breast cancer under chemotherapy. These findings can be applied to future model-based cost-effectiveness analyses.

Abstract
Background This study evaluated the cost-effectiveness of replacing standard intravenous therapy (taxane) with oral S-1 therapy for first-line metastatic breast cancer treatment. Methods This cost-effectiveness analysis was based on data from a randomized phase III trial (SELECT BC). As cost-effectiveness was a secondary endpoint of the SELECT BC trial, some of the randomized patients participated in an EQ-5D survey (N = 391) and health economic survey (N = 146). The EQ-5D responses, claims, and prescription data were collected for as long as possible until death. The expected quality-adjusted life years (QALY) obtained from each treatment were calculated using patient-level EQ-5D data, and the expected cost was calculated using patient-level claim data. The analysis was performed from the perspective of public healthcare payers. Results The estimated EQ-5D least-square means and 95% CI up to 48 months were 0.764 (95% CI, 0.741–0.782) and 0.742 (95% CI, 0.720–0.764) in the S-1 and taxane arms, respectively. The expected QALY was 2.11 for the S-1 arm and 2.04 for the taxane arm, with expected costs of JPY 5.13 million (USD 46,600) and JPY 5.56 million (USD 50,500), respectively. These results show that S-1 is cost-saving. According to probabilistic sensitivity analysis, S-1 was dominant with a probability of 63%. When the willingness to pay (WTP) value was JPY 5 million (USD 45,500) per QALY, the probability of being cost-effective was 92%. Conclusions Our results show that the introduction of oral S-1 therapy for metastatic breast cancer is highly likely to be cost-effective. Trial registration UMIN CTR C000000416.

Abstract
Objective Many studies have shown the efficacy of everolimus after pretreatment with vascular endothelial growth factor receptor-tyrosine kinase inhibitors. We investigated the efficacy and safety of everolimus as a second-line treatment after the failure of vascular endothelial growth factor receptor-tyrosine kinase inhibitor therapy in Japanese patients with advanced renal cell carcinoma. Methods This was an open-label, multicenter, phase II trial conducted in Japan through the central registration system. A total of 57 patients were enrolled. Patients were administered 10 mg of everolimus q.d. orally. The primary efficacy endpoint was progression-free survival achieved by administration of everolimus. Results The median progression-free survival of patients administered everolimus was 5.03 months (95% confidence interval: 3.70-6.20). The median overall survival was not reached. The objective response rate was 9.4% (95% confidence interval: 3.1-20.7). The progression-free survival in the group of <100% relative dose intensity was 6.70 months (95% confidence interval: 4.13-11.60), and that in the group of 100% relative dose intensity was 3.77 months (hazard ratio: 2.79, 95% confidence interval: 2.77-5.63). The commonly observed adverse events and laboratory abnormalities were stomatitis (49.1%), hypertriglyceridemia (26.4%), interstitial lung disease (26.4%), anemia (22.6%) and hypercholesterolemia (22.6%). Conclusion The median progression-free survival was almost similar to that recorded in the RECORD-1 study, whereas prolongation of overall survival was observed in the present study compared with the RECORD-1 study. The treatment outcomes of first-line vascular endothelial growth factor receptor-tyrosine kinase inhibitor therapy and second-line everolimus treatment in Japanese patients were successfully established in the present study.

Abstract
Purpose The goal of chemotherapy for metastatic breast cancer (MBC) is to prolong survival and maintain health-related quality of life. This study aimed to evaluate long-term health status of patients with MBC who participated in the phase III randomized SELECT BC trial. Methods In the SELECT BC trial, patients were randomly allocated to the S-1 or taxane (paclitaxel or docetaxel) arm. Health status was assessed by EQ-5D at pre-treatment, 3 and 6 months after randomization, and every 6 months thereafter to the extent possible. Least square mean scores were assessed to compare EQ-5D index values between groups. Time to deterioration analysis was also performed by defining the minimally important difference of EQ-5D as 0.05 or 0.1. Results The number of patients for EQ-5D analysis was 175 and 208 in the taxane and S-1 arms, respectively. Least square mean EQ-5D index values up to 60 months were 0.741 (95 % CI [0.713–0.769]) in the taxane arm and 0.748 [0.722–0.775] in the S-1 arm. The EQ-5D index value during PFS up to 12 months in the S-1 was superior to the corresponding index value in the taxane (0.812 [0.789–0.834] vs. 0.772 [0.751–0.792], P = 0.009). Time to deterioration analysis also revealed that S-1 significantly delayed the deterioration of EQ-5D index value during the period before progression (P = 0.002 and 0.003). Conclusions Our findings suggest that the EQ-5D index value was higher in patients treated with S-1 during first-line chemotherapy. Considering non-inferiority of S-1 in terms of OS, obtained quality-adjusted life years may be greater in the S-1 arm.

Abstract
BACKGROUND The valuation study of the five-level version of the EuroQol five-dimensional questionnaire (EQ-5D-5L) involved composite time trade-off (cTTO) and a discrete choice experiment (DCE). The DCE scores must be anchored to the quality-of-life scale from 0 (death) to 1 (full health). Nevertheless, the characteristics of the statistical methods used for converting the EQ-5D-5L DCE results by using TTO information are not yet clearly known. OBJECTIVES To present the Japanese DCE value set of the EQ-5D-5L and compare three methods for converting latent DCE values. METHODS The survey sampled the general population at five locations in Japan. 1098 respondents were stratified by age and sex. To obtain and compare the value sets of the EQ-5D-5L, the cTTO and DCE data were analyzed by a linear mixed model and conditional logit, respectively. The DCE scores were converted to the quality-of-life scale by anchoring to the worst state using cTTO, mapping DCE onto cTTO, and a hybrid model. RESULTS The data from 1026 respondents were analyzed. All the coefficients in the cTTO and DCE value sets were consistent throughout all the analyses. Compared with the cTTO algorithm, the mapping and hybrid methods yielded very similar scoring coefficients. The hybrid model results, however, produced a lower root mean square error and fewer health states with errors exceeding 0.05 than did the other models. The DCE anchored to the worst state overestimated the cTTO scores of almost all the health states. CONCLUSIONS Japanese value sets based on DCE were demonstrated. On comparing the observed cTTO scores, we found that the hybrid model was slightly superior to the simpler methods, including the TTO model.

Abstract
BACKGROUND AND OBJECTIVES Although quality-adjusted life-years (QALYs) may not completely reflect the value of a healthcare technology, it remains unclear how to adjust the cost per QALY threshold. First, the present study compares two survey methods of measuring people's preferences for a specific healthcare technology when each choice has the same efficiency. The second objective was to consider how this information regarding preferences could be used in decision making. METHODS We conducted single-attribute (budget allocation) and multi-attribute (discrete-choice) experiments to survey public medical care preferences. Approximately 1000 respondents were sampled for each experiment. Six questions were prepared to address the attributes included in the study: (a) age; (b) objective of care; (c) disease severity; (d) prior medical care; (e) cause of disease; and (f) disease frequency. For the discrete-choice experiment (a) age, (b) objective of care, (c) disease severity, and (d) prior medical care were orthogonally combined. All assumed medical care had the same costs and incremental cost-effectiveness ratio (ICER; cost per life-year or QALY). We also calculated the preference-adjusted threshold (PAT) to reflect people's preferences in a threshold range. RESULTS The results of both experiments revealed similar preferences: intervention for younger patients was strongly preferred, followed by interventions for treatment and severe disease states being preferred, despite the same cost per life-year or QALY. The single-attribute experiment revealed that many people prefer an option in which resources are equally allocated between two interventions. Marginal PATs were calculated for age, objective of care, disease severity, and prior medical care. CONCLUSION The single- and multi-attribute experiments revealed similar preferences. PAT can reflect people's preferences within the decision-maker's threshold range in a numerical manner.

Abstract
Abstract
Background: There is a high risk of under-reporting subjective toxicities by physicians, even when collected prospectively in clinical trials. It has been recommended to include patient reported measures regarding symptoms in prospective clinical comparative effectiveness trials. However, there have been few reports of agreement in endocrine related symptoms between patient and physician reporting.
Patients and Method: The National Surgical Adjuvant Study of Breast Cancer 06 (N-SAS BC 06) is a multicenter, randomized clinical trial of postmenopausal, hormone receptor-positive breast cancer patients, with a two-stage (preoperative and postoperative) enrollment, and intervention. The primary aim was to evaluate the need for adjuvant chemotherapy in the treatment of postmenopausal breast cancer patients who responded to neoadjuvant treatment with Letrozole (LET) for 24-28 weeks. After surgery, responders were randomized into two arms receiving either chemotherapy plus LET, or LET alone. The primary endpoint was disease-free survival, and the secondary endpoints included adverse events, quality of life and health economic evaluation. This study enrolled 497 subjects from the N-SAS BC 06 who were evaluated by Patient Reported Outcomes (PROs). The concordance rate between Clinician Reported Outcomes (CROs) and PROs in their endocrine symptoms during neoadjuvant endocrine therapy was examined. Symptoms were collected prospectively by physicians using the Common Toxicity Criteria for Adverse Events at enrollment, i.e., baseline, and 4 and 16 weeks after starting neoadjuvant LET. Patients also completed the FACT-G (General), B (Breast), ES (Endocrine Symptoms), and HADS. The endocrine symptoms according to the PROs, included nausea, hot flushes, cold sweats, headaches, and HADS-Depression score. In FACT, "Not at all" was used to express the absence of the symptoms, and "A little bit", "Some-what", "Quite a bit", and "Very much" were used to express the presence of symptoms. The HADS-Depression score threshold was 10/11. According to the CROs, grade 0 was defined as the absence of symptoms and grade 1 or more was defined as the presence of symptoms. Cohen's kappa was used to determine the concordance between CROs and PROs. The sensitivity of CROs was also calculated.
Results: The calculated point estimates of Cohen's kappa at Weeks 4 and 16 after starting neoadjuvant LET were 0.12 and 0.01 for nausea, 0.16 and 0.18 for hot flushes, 0.12 and 0.09 for cold sweats, 0.03 and 0.02 for headaches, and 0.11 and 0.11 for dysthymia/depression, respectively; the concordance was quite low. The sensitivity of CROs at Weeks 4 and 16 after starting neoadjuvant LET was 0.07 and 0.03 for nausea, 0.16 and 0.17 for hot flushes, 0.1 and 0.08 for cold sweats, 0.03 and 0.03 for headaches, and 0.11 and 0.1 for dysthymia/depression, respectively; the sensitivity was quite low.
Conclusion: This study showed that there were big differences between CROs and PROs in endocrine symptoms associated with endocrine therapy for breast cancer and that physicians could not obtain sufficient information on the endocrine symptoms. It is recommended that PROs be used to evaluate adverse events caused by endocrine therapy.

Abstract
BACKGROUND Oral fluoropyrimidines are used for the first-line treatment of metastatic breast cancer to avoid severe adverse effects, although firm supporting evidence is lacking. We aimed to establish whether S-1 is non-inferior to taxanes in this setting. METHODS We did an open-label, non-inferiority, phase 3 trial at 154 hospitals in Japan. We enrolled individuals who had HER2-negative metastatic breast cancer who had received no chemotherapy for advanced disease, and who were resistant to endocrine treatment. Patients were randomly assigned (1:1) either to taxane (docetaxel 60-75 mg/m(2) at intervals of 3-4 weeks; paclitaxel 80-100 mg/m(2) weekly for 3 of 4 weeks; or paclitaxel 175 mg/m(2) at intervals of 3-4 weeks) or to S-1 (40-60 mg twice daily for 28 consecutive days, followed by a 14-day break). Randomisation was done centrally with the minimisation method, with stratification by institution, liver metastasis, oestrogen and progesterone receptor status, previous treatment with taxanes or oral fluorouracil, and time from surgery to recurrence. The primary endpoint was overall survival, with a prespecified non-inferiority margin of 1·333 for the hazard ratio (HR). The primary efficacy analysis was done in the full analysis set, which consisted of all patients who took at least one study treatment and who had all data after randomisation. This trial is registered with the University Hospital Medical Information Network, Japan (protocol ID C000000416). FINDINGS Between Oct 27, 2006, and July 30, 2010, we enrolled 618 patients (309 assigned to taxane; 309 assigned to S-1). The full analysis set consisted of 286 patients in the taxane group and 306 in the S-1 group. Median follow-up was 34·6 months (IQR 17·9-44·4). Median overall survival was 35·0 months (95% CI 31·1-39·0) in the S-1 group and 37·2 months (33·0-40·1) in the taxane group (HR 1·05 [95% CI 0·86-1·27]; pnon-inferiority=0·015). The most common grade 3 or worse adverse events were neutropenia (20 [7%] of 307 patients in the S-1 group vs nine [3%] of 290 patients in the taxane group), fatigue (ten [3%] vs 12 [4%]), and oedema (one [<1%] vs 12 [4%]). Treatment-related deaths were reported in two patients in the taxane group. INTERPRETATION S-1 is non-inferior to taxane with respect to overall survival as a first-line treatment for metastatic breast cancer. S-1 should be considered a new option for first-line chemotherapy for patients with HER2-negative metastatic breast cancer.

Abstract
Previous cost-effectiveness analyses (CEAs) of abiraterone for castration-resistant prostate cancer (CRPC) patients have not shown favorable results for this new drug. These CEAs were generally conducted based on models used in clinical trials, where comparisons were made with patients given placebos. However, details on any other therapies provided to the comparison groups were not analyzed. These additional therapies should be considered when conducting CEAs to ensure better applications to clinical practice and policymaking. The objective of this study was to elucidate the actual therapies provided to CRPC patients using real-world claims data. We obtained anonymized computerized health care claims data of Japanese prostate cancer patients from the Japan Medical Data Center. This database comprises data from more than 2.5 million insured persons aged below 75 years from over 50 companies between January 2005 and June 2013. From among the prostate cancer patients, we identified CRPC patients as those who had been administered docetaxel, and further investigated their treatments and health care costs. Health care costs were estimated using a regression model accounting for variations in inpatient care, chemotherapies, death, and age. We identified 2138 prostate cancer patients, 36 of whom had been administered docetaxel. We excluded patients diagnosed with other cancers, resulting in a final sample of 18 cases. Of these, 66.7 % were administered other types of chemotherapy, which had not been considered in the control groups in most previous CEAs. We estimated mean health care costs for CRPC to be approximately US$952 per patient per month, and found that these costs were significantly affected by inpatient care and chemotherapy use. Actual therapies include a variety of treatments for CRPC patients, including various types of chemotherapy. Our study estimated health care costs based on real-world claims data. This study contributes to future CEAs by not only providing an estimate of health care costs for these patients, but also demonstrating that the actual therapies provided to comparison groups should be considered when conducting CEAs.

Abstract
PURPOSE To assess the joint symptoms and the impact on patients' health-related quality of life (HRQOL) due to 5 years of anastrozole from the baseline data in the N-SAS BC 05 trial, a randomized clinical trial was designed to assess the efficacy of 5 additional years of anastrozole among women with breast cancer. METHODS Joint symptoms and HRQOL were evaluated using an original questionnaire for joint symptoms, the Short Form 36-item Health Survey (SF-36), the EuroQol EQ-5D-3L, and a subscale of the Functional Assessment of Cancer Therapy-Endocrine Symptoms (FACT-ES). RESULTS Baseline joint symptom and HRQOL data were collected from 330 patients between November 2007 and March 2010. Joint pain and joint stiffness were reported by 61.6 and 59.1 % of patients, respectively, although these symptoms did not affect the activities of daily living in 96.0 and 97.9 % of patients, respectively. Joint pain was reported in the knee by 61.0 % of patients and in the hand by 36.0 % of patients. Joint stiffness mainly affected the hand (67.9 %), especially the proximal interphalangeal joint, and typically occurred upon waking up or in the morning. Most SF-36 domains had good average scores, although slight decreases in physical functioning and role-physical were observed (compared to the national standard scores). The mean EQ-5D utility score was 0.86, and the total FACT-ES subscale score was 62.2/76. CONCLUSIONS After 5 years of anastrozole, many of the patients reported joint pain and stiffness in mainly the hand and knee with mild symptoms and good HRQOL.

Abstract
Abstract
Background: Treatment goals of metastatic breast cancer (MBC) are to prolong survival and improve health-related quality of life (HRQOL). Current standard first-line chemotherapy for MBC are the taxanes or anthracyclines; however treatment-related adverse events greatly reduce HRQOL. S-1 is an oral 5-fluorouracil derivative, and phase II trials showed good clinical efficacy and tolerability. We conducted a phase III randomized controlled trial to establish non-inferiority of S-1 in overall survival (OS) and superiority in HRQOL to taxanes, when given as first-line chemotherapy for MBC.
Methods: Patients with HER2-negative non-life-threatening MBC, naïve to chemotherapy for metastatic disease, were randomly assigned to the taxane or S-1 groups. In the taxane group, patients received docetaxel 60-75mg/m2 q3w, paclitaxel 80-100mg/m2 q1w, or paclitaxel 175 mg/m2 q3w according to institutional policy. In the S-1 group, patients received S-1 40–60 mg twice daily based on body surface area using a 28 days on;14 days off regimen. Treatment was repeated until tumor progression or for at least 6 cycles (taxane) or 4 cycles (S-1). After failure of the first-line protocol therapy, another cytotoxic agent was administered, based on the investigator’s discretion. HRQOL was assessed with the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30, the Patient Neurotoxicity Questionnaire (PNQ) and the EQ-5D at baseline and 3, 6, 12 months after the start of the treatment. The primary endpoint was OS. Secondary endpoints were time to treatment failure (TTF), adverse events, and HRQOL.
Results: A total of 618 women were enrolled. After a median follow-up of 34.6 months, median OS was 37.2 months in the taxane group (n=309) and 35.0 months in the S-1 group (n=309) (hazard ratio [HR] 1.05, 95% confidence interval [CI] 0.86–1.27, non-inferiority test p=0.015). Median TTF was 8.9 months in the taxane group and 8.0 months in the S-1 group (HR 1.10, 95% CI 0.93–1.30, p=0.022). The incidence of the following grade 3-4 adverse events, allergic reaction, edema and sensory neuropathy, were statistically significantly more frequent in the taxane group (p=0.038, 0.0013 and 0.0077, respectively). Hematologic and non hematologic toxicities except above did not differ significantly between the two groups. The results of the EORTC QLQ-C30 under study treatment indicated that the S-1 was better than the taxanes in global health status/QOL (p=0.044), physical functioning (p=0.002), role functioning (p=0.002), emotional functioning (p=0.004), cognitive functioning (p=0.026), social functioning (p<0.0001), pain (p=0.042) and financial difficulties (p=0.003). EQ-5D utility scores were significantly higher in the S-1 group (p=0.033) during the first year. PNQ sensory and motor scores were significantly better in the S-1 group (p<0.0001 and p=0.0002, respectively).
Conclusions: This study clearly demonstrated that S-1 was superior to taxanes in terms of HRQOL and toxicity, without compromising the prolonged OS. S-1 should be considered as a new standard for first-line chemotherapy for MBC. We are conducting another similar trial (UMIN000005449) that compares first-line anthracycline with S-1 in terms of OS and HRQOL.

Abstract
Abstract
Background: Altered appearance due to chemotherapy is a very distressing adverse event and can remain unrecovered for a long time after chemotherapy. To clarify the current status of appearance change and its support systems, we conducted a national questionnaire survey of patients with breast cancer who had received chemotherapy in Japan. Here, we report on the long-term recovery of scalp hair loss during and after chemotherapy.
Patients and methods: A questionnaire was distributed to patients in hospitals throughout Japan between April and October 2013. The questionnaire was regarding the current status of the patients’ appearance issues (scalp hair, eyebrows, eyelashes, nails, skin) related to chemotherapy and its support systems, including chemotherapy regimens received, endocrine therapy received, and duration after chemotherapy. Eligible patients were women with breast cancer without any recurrence who had received adjuvant or neoadjuvant chemotherapy containing anthracycline (A) and/or taxanes (paclitaxel, P; docetaxel, D) and who were within 5 years from the last chemotherapy treatment. The physicians of each hospital asked their patients to fill out the questionnaire and mail it directly to the data center. The scalp hair status was analyzed in a cross-sectional manner according to the duration from chemotherapy.
Results: The questionnaires were returned from 1511 patients in 47 hospitals (response rate, 82%; 1511/1853). Thirty-three patients were excluded, mainly because >5 years had passed since chemotherapy. In total, 1478 questionnaires were ultimately analyzed. The median age was 50 (range, 17–79) years. The distribution of patients according to time from the last chemotherapy treatment was as follows: <1 year, 28%; 1–2 years, 24%; 2–3 years, 19%; 3–4 years, 15%; and 4–5 years, 13%. During chemotherapy, scalp hair loss occurred in 98.4% of the patients, and 94% experienced >80% hair loss. Hair growth began during chemotherapy in 13.1% of patients and after chemotherapy in 80.3% (6.6% left the question unanswered). Within 6 months from the start of hair growth, 65% of patients felt a change in hair thickness, while 82% felt it was becoming thin. Of the patients, 70% felt a change in quality, while 48% felt that it had become unruly; 44% felt a color change, while 80% felt that they were growing more gray hair. Of the patients who answered the questions, >80% hair volume recovery was seen in 52.7% of patients within 1 year; in 63.5%, in 1–3 years; and in 61.7%, even after 3 years. After 3 years, volume recovery was seen in 67.8% of patients after an A+P–containing regimen; in 43.4%, after A+D; in 63.5%, after D; and in 88.9%, after A. Patients who had received A+P, D, and A+D had significantly less volume recovery than patients who had received A (P<0.001 for all).
Conclusions: Almost all patients with breast cancer experienced severe hair loss during standard chemotherapy, but a recovery trend was noted after chemotherapy. However, hair remained unrecovered to various degrees in a significant number of patients even 3–5 years after chemotherapy, especially in those who had received taxane-containing regimens. We should consider the support needs of patients who experience chemotherapy-induced hair loss.

Abstract
Abstract
Background: Many breast cancer patients suffer hair loss due to chemotherapy, and not only scalp hair loss, but also eyebrow loss, eyelash loss and nail changes induced by chemotherapy are traumatic for patients. These side effects diminish self-esteem and greatly reduce quality of life. However, there has been little research in this field until now. To clarify the actual situation concerning appearance issues in breast cancer patients who received adjuvant chemotherapy, and to consider a support system for these patients, we conducted a questionnaire survey.
Methods: Disease-free breast cancer patients who have received adjuvant chemotherapy containing anthracycline and/or taxane within 5 years were recruited from 47 hospitals or clinics in Japan from April to October 2013. The patients participating in this survey completed a 65-question questionnaire concerning appearance issues (48) and their perception of physical and non-physical side effects (17). The drugs administered and treatment period were filled out by their doctors beforehand. The completed questionnaires were mailed directly to the data center by the patients.
Results: A total of 1511 patients returned the questionnaire to the data center with a response rate of 82% (1511/1853). Since 33 patients did not meet the entry criteria, the questionnaires returned by 1478 patients were analyzed in this survey. The mean age was 54.7 years (+-10.4, range 17-79). The distribution of the patients by time from the end of chemotherapy to this survey was as follows: < 1 year: 28%; 1 to 2 years: 24%; 2 to 3 years: 19%; 3 to 4 years: 15%; 4 to 5 years: 13%. In this survey, the side effect that most patients (92%) considered traumatic was hair loss. The second most traumatic side effect was fatigue (83%), while the 7th place was taken by nail changes (72%) and nausea/vomiting was in the 10th place (56%). During chemotherapy, scalp hair loss occurred in 98% of patients. Eyebrows fell out in 90% and complete eyebrow loss occurred in 36%. Eyelashes fell out in 88% and complete eyelash loss occurred in 37%. Fingernail changes occurred in 77% and toenail changes in 62%. In 60-70%, scalp hair, eyebrow and eyelashes recovered to the original appearance by 1 to 1.5 years after chemotherapy, but in 3-7%, scalp and face hair loss did not recover at all by 1 to 1.5 years. This proportion remained almost the same for 1.5 to 5 years too. During or after chemotherapy, 84% of patients used wigs. This decreased to 47% by 1 year after chemotherapy and 15.2% by 1.5 years. However 10% of patients were still using a wig 4 to 5 years after chemotherapy. Approximately 30% of the patients had trouble using and selecting a wig. In 51% of the patients, sufficient information on scalp hair loss was obtained. However, sufficient information on eyebrow loss, eyelash loss and nail changes was only obtained from 28%, 25% and 31%, respectively.
Conclusions: Our survey demonstrated the outline of hair loss and appearance issues in breast cancer patients who received chemotherapy. Hair loss is the most distressing and occasionally long-lasting side effect. Lack of information is a serious problem. These facts suggested a need for long-time and careful support of these patients.

Abstract
455 Background: Everolimus has shown the efficacy and the safety in the phase III trial (RECORD-1) in patients with mRCC after failure of Vascular Endothelial Growth Factor Receptor-TKI. However, 26% of patients received two TKIs (sunitinib and sorafenib) as previous therapy in RECORD-1. In addition, as pre-treatment before TKI, 65% of patients received cytokine therapy and 13% of patients received chemotherapy. Therefore, there is still no clear evidence of everolimus as second line setting after failure of 1st-line TKI therapy. Methods: This study is an open-label, multi-center, single-arm, phase II trial. Primary endpoint is progression-free survival (PFS), and secondary endpoints are overall survival, objective response rate, time-to-treatment-failure, safety and quality of life (EORTC QLQ-C30, FKSI-DRS, EQ-5D). Key eligibility criteria are RCC with clear cell component, patients who received one TKI as first line therapy, patients who did not receive cytokine and chemotherapy and ECOG performance status 0-1. Results: 57 patients were enrolled from 02/11 to 12/12. Median age was 63 years, common sites of metastasis were lung (32.7%) and bone (12.2%), 79.6% had previous nephrectomy, previous TKI therapy were sunitinib (69.4%), sorafenib (22.4%) and axitinib (8.2%). Median PFS was 4.4 months (95% confidence interval: 3.7-6.0). 8.2% had partial response and 57.1% had stable disease according to RECIST v.1.0. The incidence of adverse events (AEs) of all grades was 95.9%. Major AEs were stomatitis (49.0%), hypertriglyceridemia (26.5%) and hypercholesterolemia (24.5%). Serious AEs were stomatitis (10.2%), interstitial lung disease (6.1%) and rash (6.1%). There were no treatment related deaths. All QOL scores were not changed at 2 months, while dyspnea and global health scores of EORTC QLQ-C30 and FKSI-DRS score were worsened at 4 months. Conclusions: This study is a first report of everolimus as second line setting after failure of 1st-line TKI. Further study and long-term follow-up would be warranted. Clinical trial information: UMIN000004742.

Abstract
OBJECTIVES When quality-adjusted life-years are used for economic evaluation, the controversial issue of "double counting" of productivity loss emerges, particularly given the lack of empirical data. METHODS In this study, we performed a Web-based, large-sample survey to address the issue of double counting. To determine the influence of income reduction on utility scores, we obtained utility scores of eight health states with three instruction types: a) no instruction, b) instructed to consider income reduction, and c) instructed not to consider income reduction (compensated). Respondents were randomly sampled from the online panel and asked to evaluate 1 of 24 patterns by both standard gamble and time trade-off methods. RESULTS A total of 6551 respondents completed the questionnaire. First, despite the lack of instruction on income reduction, many respondents spontaneously assumed lost income. The proportion tended to be higher when considering more severe health states. Second, the degree of assumed income reduction was related to utility scores. For a 10% income reduction, respondents assumed a 0.02- to 0.04-decrease in utility score (both standard gamble and time trade-off methods). Third, utility scores did not change significantly when instruction was given not to consider income reduction (compensated) compared with when no instruction was given. CONCLUSIONS An assumed income reduction clearly influenced utility scores; however, compensation for lost income failed to sufficiently improve utility scores. In our view, the effect of income on utility scores does not only reflect wage loss. Our results suggest that the impact of double counting is negligible.

Abstract
The Functional Assessment of Cancer Therapy-Anemia (FACT-An) was developed to measure the effect of anemia on quality of life (QOL) in cancer patients. We have previously validated the Japanese version of the FACT-An in Japanese cancer patients receiving chemotherapy, hormone therapy, or radiation therapy. That analysis was limited to evaluating the relationship between QOL scores and hemoglobin (Hb) levels. In this study, the data were further analyzed in order to identify factors that affect QOL. The mean Hb level of the patients was unchanged over three months. Patient age, Eastern Oncology Group Performance Status (ECOG-PS) score, Hb level, and the type of treatment method received were each predictive factors of a patient's FACT-An score at baseline, while the patient's Hb level at three months and whether the patient had received a blood transfusion were both predictive factors of a patient's FACT-An score at three months. Anemia consistently negatively affected the QOL of cancer patients measured over a three-month period. These results confirm the clinical effectiveness of the FACT-An as a tool to assess anemia-related QOL in Japanese cancer patients.

Abstract
Abstract
Background: It is critically important to consider the issue of treatment for older breast cancer patients in developed countries where aging has been rapidly advanced such as in Japan. According to Oxford Overview analysis of 15-year results, benefit of adjuvant chemotherapy in older than 70 years remains uncertain. Recently CALGB 49907 trial clearly showed standard chemotherapy of either cyclophosphamide, methotrexate, and fluorouracil (CMF) or doxorubicin plus cyclophosphamide (AC) is superior to capecitabine in patients with early-stage breast cancer who are 65 years or older. In contrast, we demonstrated equivalent efficacy between six cycles of classical CMF and 2 years of oral Tegafur-uracil (UFT) in phaseIII randomized controlled trial: N-SAS BC01 (Watanabe T et al, JCO 2009). Of interest, UFT showed a trend toward better suppression of recurrence in patients over 50 years of age in this trial. In current exploratory analysis, we sought to examine whether UFT is not inferior to CMF in terms of efficacy, toxicity and quality of life (QOL) in older patients with early-stage breast cancer.
Patients and Methods: N-SAS BC 01 trial was a randomly assigned trial comparing adjuvant oral UFT with classical CMF in patients with node negative, high risk breast cancer. In this exploratory analysis, patients of 65 years or older enrolled in N-SAS BC 01 trial were analyzed in terms of efficacy, toxicity and quality of life.
Results: Of the 707 patients enrolled in N-SAS BC 01 trial, 97 patients (13.7%) were 65 years or older. Median age was 68 years (range, 65 to 75 years). The 5-year relapse-free survival (RFS) rate was 92.5% in the CMF arm and 93.0% in the UFT arm. Overall survival (OS) rate at 5 years were 98.1% and 97.7%, respectively. The hazard ratios of the UFT arm relative to the CMF arm were 1.07 for RFS (95% CI, 0.31 to 3.55) and for OS (95% CI, 0.15 to 10.25). However 95 % CIs were very wide due to the small sample size. Among patients who received CMF, frequency of grade 3/4 leukopenia (3.8%) and neutropenia (13.5%) were higher than 0% and 4.8% with UFT, respectively. Similarly, grade 3/4 increased liver enzyme and nausea/vomiting were more frequent with CMF than with UFT. In contrast, elevation of total bilirubin and diarrhea were more observed in UFT arm. Compared with patients received CMF, patients with UFT had better QOL scores assessed by EORTC QLQ-C30/BR23 and the FACT-B questionnaire. The rate of adherence was 79.2% (42/53) at 6 months in the CMF arm and 74.4% (32/43) at 2 years in the UFT arm.
Conclusion: The result of this study indicated that UFT might not be inferior to CMF in patient with early stage breast cancer who are 65 years of age or older in terms of efficacy, toxicity and QOL. UFT would be a promising option for adjuvant chemotherapy in older women with node-negative, high-risk breast cancer. Further larger randomized clinical trial in this patient population would be warranted to validate these results.

Abstract
Abstract
Background: Sensory loss or paresthesia due to division of the intercostobrachial nerve (ICBN) is a complication of axillary lymph node dissection (ALND). Preservation of the ICBN may be of value, but few prospective studies have shown an impact of preservation on sensory changes or health related quality of life (HRQOL) after breast cancer surgery.
Methods: Prospective study was performed to evaluate the association of ICBN preservation with sensory change and HRQOL at 1 (baseline), 6, 12 and 24 months after breast cancer surgery in 140 patients. The sensory examination included dysesthesia, paresthesia, abnormal touch and pain sensation in the upper arm.
Results: Division of the ICBN did not influence the frequency or severity of subjective dysesthesia and paresthesia. There was no marked difference in touch or pain sensation at baseline between patients with a preserved (group P) and divided (group D) ICBN. In group P, the percentage of patients aware of a sensory deficit or loss decreased with time, and that of patients aware of a hypersensitive sensation increased. These changes did not occur in group D, leading to a significant difference between the groups at 24 months. The main difference between the groups was the area with reduced touch or pain sensation. This area decreased with time in group P, but not in group D. ICBN preservation or division did not influence HRQOL.
Conclusion: ICBN preservation in ALND has a benefit of a reduced area with long-term axillary hypoesthesia, but has no influence on improvement of pain and HRQOL.

Abstract
PURPOSE To elucidate whether adjuvant taxane monotherapy is a feasible and tolerable for postoperative breast cancer patients, we evaluated the severity of chemotherapy-induced peripheral neuropathy (CIPN) and the relative tolerability of regimens by health-related quality of life (HRQOL) assessment in node-positive breast cancer patients treated with taxane-containing regimens. METHODS We evaluated CIPN and HRQOL in the first 300 patients enrolled in a larger (1,060 total) multicenter phase III trial randomized to one of four adjuvant regimens: (1) anthracycline-cyclophosphamide followed by paclitaxel (ACP), (2) AC followed by docetaxel (ACD), (3) paclitaxel alone (PTX), or (4) docetaxel alone (DTX). CIPN was assessed by the Patient Neurotoxicity Questionnaire (PNQ) and the National Cancer Institute Common Toxicity Criteria, and HRQOL by Functional Assessment of Cancer Therapy-General (FACT-G). CIPN and HRQOL scores were compared between ACP and ACD vs. PTX and DTX, and ACP and PTX vs. ACD and DTX. RESULTS PNQ sensory scores were significantly higher in patients treated with taxane monotherapy compared to treatment with AC followed by taxane (P = .003). No significant differences in PNQ sensory scores were observed between the ACP and PTX vs. ACD and DTX regimens (P = .669). Regardless of taxane regimen, PNQ severity scores for CIPN appear to be largely reversible within 1 year of adjuvant treatment. No significant difference in FACT-G scores was observed between any regimens during the study treatments. CONCLUSIONS Patient-reported CIPN was significantly more severe with single-agent adjuvant taxane compared to AC followed by taxane treatment; however, the HRQOL findings support that single-agent taxane treatment is tolerable.

Abstract
OBJECTIVE To elucidate the time course of taxane-induced edema which may affect the patients' quality of life (QOL). PATIENTS AND METHODS Our study included the first 300 Japanese patients assigned to 1 of 4 regimens using docetaxel (DTX) or paclitaxel (PTX) by 1:1:1:1 in a randomized controlled trial to evaluate the efficacy of adjuvant therapies for node-positive breast cancer. Patients' QOL was prospectively assessed by the functional assessment of cancer therapy (FACT)-breast and -taxane (FACT-T) subscale. The scores of FACT items regarding edema and body weight were used as indicators of edema. RESULTS The scores for 'anasarca', 'edema of the hands' and 'edema of the legs and feet' of the FACT-T subscale worsened up to 1-2 months after chemotherapy, and body weights increased remarkably until cycle 8 in patients treated with DTX alone (75 mg/m(2), 8 cycles, every 3 weeks). Edema-related symptoms and body weight were relatively stable in the other treatment groups. There were statistically significant differences in the scores of those items and in the changes of body weight both between the DTX-alone group and the other three groups combined, and between the groups using DTX and those using PTX. CONCLUSION Many patients receiving DTX for >4 cycles suffered significantly from edema.

Abstract
OBJECTIVE To evaluate the cost-effectiveness of adjuvant FOLFOX therapy versus 5-fluorouracil/leucovorin (FU/LV) for patients with stage III colorectal cancer. METHODS We performed the cost-effectiveness of FOLFOX compared with standard FU/LV treatment by the retrospective analysis of patient-level data from the randomized controlled Multicenter International Study of Oxaliplatin, 5-Fluorouracil, and Leucovorin in the Adjuvant Treatment of Colon Cancer (MOSAIC) trial. Predicted mean time spent in each disease state was calculated by our statistical model, which takes into account the cure rate and treats death from causes other than colon cancer as a competing risk. We performed this analysis from the perspective of the health-care payer. Using a time horizon of 30 years, both cost and effectiveness were discounted by 3% per year. RESULTS Estimated cure rates for colon cancer were 0.715 (FOLFOX) and 0.622 (FU/LV). Estimated medical costs of FOLFOX were JPY 3.1 million (USD 34,000) compared with JPY 1.9 million (USD 22,000) of FU/LV. The mean estimated quality-adjusted life-year was 9.83 with FOLFOX and 9.07 with that of FU/LV. The incremental cost-effectiveness ratio of FOLFOX was JPY 1.5 million (USD 17,000) per quality-adjusted life-year compared with FU/LV, which was supported by sensitivity analysis. Even if we assume that Japanese outcomes were better than those reported by the MOSAIC trial, which would reduce the difference between cure rates for each treatment to 5%, the incremental cost-effectiveness ratio remained below 5.0 million (USD 56,000) per quality-adjusted life-year. CONCLUSIONS Adjuvant FOLFOX is a cost-effective treatment for stage III colon cancer in Japan compared with FU/LV therapy. Even when parameters were changed to reflect smaller improvements with FOLFOX, the conclusion is the same.

Abstract
Health-related quality of life (HRQOL), symptoms of depression, and adverse events (AEs) were compared between Japanese postmenopausal patients with hormone-sensitive breast cancer (BC) who received adjuvant tamoxifen, exemestane, or anastrozole in an open-labeled, randomized, multicenter trial designated as the National Surgical Adjuvant Study of Breast Cancer (N-SAS BC) 04 substudy of the Tamoxifen Exemestane Adjuvant Multinational (TEAM) trial. During the first year of treatment, HRQOL and symptoms of depression were analyzed using the Functional Assessment of Cancer Therapy-Breast (FACT-B) and its Endocrine Symptom Subscale (ES), and the Center for Epidemiologic Studies Depression Scale (CES-D), respectively. In addition, predefined AEs were analyzed. A total of 166 eligible patients were randomly assigned to receive adjuvant tamoxifen, exemestane, or anastrozole. FACT-B scores increased after treatment began and remained significantly higher in the tamoxifen group than in the exemestane group or anastrozole group during the first year (P = 0.045). FACT-B scores were similar in the exemestane group and anastrozole group. ES scores and CES-D scores were similar in all treatment groups. Arthralgia and fatigue were less frequent, but vaginal discharge was more frequent in the tamoxifen group than in the exemestane group or anastrozole group. HRQOL was better in Japanese postmenopausal women treated with tamoxifen than those treated with exemestane or anastrozole. HRQOL and AEs were similar with exemestane and anastrozole. Given the results of the TEAM trial, upfront use of tamoxifen followed by an aromatase inhibitor (AI) may be an important option for adjuvant endocrine therapy in Japanese postmenopausal women.
