Review
INTRODUCTION
Non-small cell lung cancer (NSCLC) frequently presents at an incurable stage, and a majority of patients will be considered for palliative chemotherapy at some point in their disease. This article reviews the growing evidence for first-line treatment in NSCLC.
METHODS
Studies of first-line chemotherapy regimens including new agents (docetaxel, gemcitabine, irinotecan, paclitaxel, pemetrexed, and vinorelbine) and targeted agents (bevacizumab, erlotinib, and gefitinib) were identified through Medline, Embase, the Cochrane databases, and web sites of guideline organizations.
RESULTS
Two evidence-based guidelines, 10 systematic reviews, and forty-six randomized trials were eligible for inclusion. Randomized studies suggest that platinum-based doublets (platinum plus new agent) are the standard of care for first-line systemic therapy. No one new agent is clearly superior for use in combination with a platinum agent. The survival advantage of platinum-based doublets over nonplatinum combinations or older combinations is modest. The addition of bevacizumab to carboplatin and paclitaxel has shown improved survival, although multiple exclusion criteria limit the applicability of these data to a subset of patients. In patients at least 70 years of age or with Eastern Collaborative Oncology Group performance status 2, a new single agent is an alternative. Treatment beyond four to six cycles impedes quality of life without prolonging life. Emerging data suggest that the choice of chemotherapy agent may be influenced by histologic subtype.
CONCLUSION
In NSCLC, a combination of a platinum agent plus a new agent continues to be the standard of care. As differences between regimens are small, toxicity and patient preference should help guide regimen choice.

BACKGROUND
In the past years, many reports on Kanglaite were publicated in China, researchers across the country. The aim of this study is to review the effectiveness and safety of Kanglaite for treating advanced non-small-cell lung cancer.
METHODS
Authors searched the Cochrane Library, Pubmed, Embase, Cancerlit, CBM, CNKI and VIP. Mannual and additional search were also conducted. All randomized controlled trials/quasi-RCT comparing Kanglaite with other lung cancer treatment were included. Two reviewers independently performed data extraction and appraised the publications using the Juni instrument, disagreements were resolved by consensus. Double data were entered and analyzed by RevMan 4.2 software are by Cochrane Collaboration.
RESULTS
Sixteen reports were included in the meta-analysis. The quality of 16 studies was low. Pooling data of 5 studies indicated that the effect of Kanglaite+NP (Vinorelbine+Cisplatin) was better than NP with RR 1.46, 95% Confidence Interval 1.13 to 1.91. Pooling data of 3 studies of MVP (Mitomycin+Vindsine+ Cisplatin) plus Kanglaite indicated that the effect was better with RR 1.84, 95%CI 1.22 to 2.76. Pooling data of 2 studies showed that the effect of GP (Gemcitabine+Cisplatin) plus Kanglaite was better than GP with RR 1.63, 95%CI 1.09 to 2.43. Fourteen studies revealed that Kanglaite may reduce the side-effect induced by regular treatment. Ten studies showed regular treatment plus Kanglaite can stabilite/improve quality of life.
CONCLUSIONS
Kanglaite can enhance clinical effect of regular treatment, reduce side-effect and stabilite/improve quality of life, but the effect of Kanglaite being used in clinical settings needs to be confirmed by further large and multicenter.

Review
OBJECTIVES
To assess the clinical effectiveness and cost-effectiveness of gemcitabine, used in combination with paclitaxel, as a second-line treatment for people with metastatic breast cancer who have relapsed following treatment with anthracycline-based chemotherapy.
DATA SOURCES
Electronic databases were searched from inception to March 2006. Clinical advisers were also consulted.
REVIEW METHODS
A systematic review of the literature was undertaken to appraise the clinical and cost-effectiveness of gemcitabine. A Markov state transition model was developed for the economic evaluation.
RESULTS
The systematic review identified only one randomised controlled trials (RCT), and this has not yet been fully published. The methodological quality and quality of reporting of the included trial were assessed to be poor using standard criteria, but this may be due to the lack of information in the limited publications rather than being a fair reflection of the trial's quality. This RCT compared gemcitabine and paclitaxel therapy with paclitaxel monotherapy in 529 patients with metastatic breast cancer who had previously received anthracyclines, but no prior chemotherapy for metastatic breast cancer. Approximately 71% of the gemcitabine/paclitaxel patients survived for 1 year, compared with 61% of the paclitaxel group. The hazard ratio showed a 26% lower chance of survival in the paclitaxel group, and time to progressive disease was also shorter in this group. The overall response rate was higher in the gemcitabine/paclitaxel group than in the paclitaxel group. Adverse events, particularly neutropenia, were more common with gemcitabine/paclitaxel combination therapy than with paclitaxel therapy alone. The economic model was run for a simulation of 1000 patients, assuming that chemotherapy continued until patients' disease progressed. This base-case analysis found an incremental cost-effectiveness ratio (ICER) of 58,876 pounds per quality-adjusted life-year (QALY) gained and 30,117 pounds per life-year gained. The model was re-run with treatment restricted to a maximum of six cycles per patient, reflecting normal practice. This yielded an ICER of 38,699 pounds per QALY gained and 20,021 pounds per life-year gained.
CONCLUSIONS
The review of clinical effectiveness is based on data from a single RCT that has not yet been fully published. While only tentative conclusions can be drawn from this, the evidence may indicate that treatment with gemcitabine and paclitaxel confers an improved outcome for patients in terms of survival and disease progression, but at the cost of increased toxicity. An economic model developed for this review reflects high costs per QALY for this treatment combination. The base-case analysis shows high ICERs, with costs per QALY gained close to 60,000 pounds. Adopting a more realistic treatment protocol, with chemotherapy limited to a maximum of six cycles, gives a more favourable cost-effectiveness estimate. However, this was still higher than would usually be considered to be a cost-effective treatment from the NHS's perspective. Future research recommendations include an update of this review in 12-18 months' time, by which time the included RCT should be fully published. It would also be useful to compare gemcitabine with currently used treatments for metastatic breast cancer, including capecitabine and vinorelbine.

Review
Non-hormonal systemic therapy in men with hormone-refractory prostate cancer and metastases: a systematic review from the Cancer Care Ontario Program in Evidence-based Care's Genitourinary Cancer Disease Site Group.
BACKGROUND
Prostate cancer that has recurred after local therapy or disseminated distantly is usually treated with androgen deprivation therapy; however, most men will eventually experience disease progression within 12 to 20 months. New data emerging from randomized controlled trials (RCTs) of chemotherapy provided the impetus for a systematic review addressing the following question: which non-hormonal systemic therapies are most beneficial for the treatment of men with hormone-refractory prostate cancer (HRPC) and clinical evidence of metastases?
METHODS
A systematic review was performed to identify RCTs or meta-analyses examining first-line non-hormonal systemic (cytotoxic and non-cytotoxic) therapy in patients with HRPC and metastases that reported at least one of the following endpoints: overall survival, disease control, palliative response, quality of life, and toxicity. Excluded were RCTs of second-line hormonal therapies, bisphosphonates or radiopharmaceuticals, or randomized fewer than 50 patients per trial arm. MEDLINE, EMBASE, the Cochrane Library, and the conference proceedings of the American Society of Clinical Oncology were searched for relevant trials. Citations were screened for eligibility by four reviewers and discrepancies were handled by consensus.
RESULTS
Of the 80 RCTs identified, 27 met the eligibility criteria. Two recent, large trials reported improved overall survival with docetaxel-based chemotherapy compared to mitoxantrone-prednisone. Improved progression-free survival and rates of palliative and objective response were also observed. Compared with mitoxantrone, docetaxel treatment was associated with more frequent mild toxicities, similar rates of serious toxicities, and better quality of life. More frequent serious toxicities were observed when docetaxel was combined with estramustine. Three trials reported improved time-to-disease progression, palliative response, and/or quality of life with mitoxatrone plus corticosteroid compared with corticosteroid alone. Single trials reported improved disease control with estramustine-vinblastine, vinorelbine-hydrocortisone, and suramin-hydrocortisone compared to controls. Trials of non-cytotoxic agents have reported equivocal results.
CONCLUSION
Docetaxel-based chemotherapy modestly improves survival and provides palliation for men with HRPC and metastases. Other than androgen deprivation therapy, this is the only other therapy to have demonstrated improved overall survival in prostate cancer in RCTs. Further investigations to identify more effective therapies for HRPC including the use of systemic therapies earlier in the natural history of prostate cancer are warranted.

Comparative Study Review
OBJECTIVE
To examine the clinical effectiveness and cost-effectiveness of oral capecitabine for locally advanced and metastatic breast cancer in relation to its licensed indications.
DATA SOURCES
Twenty-three electronic databases and other databases of ongoing research and Internet resources, bibliographies of retrieved articles and industry submissions.
REVIEW METHODS
Two reviewers independently screened and assessed all titles and/or abstracts including economic evaluations. Randomised controlled trials (RCTs) and observational studies that investigated capecitabine monotherapy, in patients pretreated with an anthracycline-containing regimen or a taxane, or capecitabine in combination with docetaxel, in patients pretreated with an anthracycline-containing regimen, were included. The economic evaluation was based on data reported in the manufacturer's submission.
RESULTS
For capecitabine monotherapy, 12 uncontrolled observational studies were identified. The methodological quality of the studies was low. Capecitabine demonstrated antitumour activity, but was associated with a particular risk of hand-foot syndrome and diarrhoea. Economic evaluation was hampered by the poor quality of the published studies, but compared indirectly with vinorelbine, capecitabine was associated with lower costs and improved patient outcomes. For capecitabine in combination with docetaxel, one RCT was identified. Combination therapy was superior to single-agent docetaxel in terms of survival, time to disease progression and overall response. Adverse events occurred more frequently with combination therapy. The economic evaluation demonstrated an overall improved QALY score for combination therapy with a slight reduction in costs.
CONCLUSIONS
No conclusions could be drawn regarding the therapeutic benefit of capecitabine monotherapy; RCTs are required. Capecitabine appeared cost-effective compared with vinorelbine, but serious doubts remain; the poor quality of the trials may invalidate this conclusion. Based on limited evidence, combination therapy was more effective than single-agent docetaxel and likely to be cost-effective, but was associated with higher incidences of hand-foot syndrome, nausea, diarrhoea and stomatitis.

Review
BACKGROUND
The incidence of lung cancer is declining following a drop in smoking rates, but it is still the leading cause of death from cancer in England and Wales, with about 30,000 deaths a year. Survival rates for lung cancer are poor everywhere, but they appear to be better in the rest of the European Community and the USA than in the UK. Only about 5 per cent of people with lung cancer survive for 5 years, and nearly all of these are cured by surgery after fortuitously early diagnosis. At present, only a small proportion of patients (probably about 5 per cent) with non-small-cell lung cancer are being given chemotherapy. Some centres treat a greater proportion.
OBJECTIVES
This review examines the clinical effectiveness and cost-effectiveness of four of the newer drugs - vinorelbine, gemcitabine, paclitaxel and docetaxel - used for treating the most common type of lung cancer (non-small-cell lung cancer). The first three drugs are used for first-line treatment, but at present docetaxel is used only after first-line chemotherapy has failed.
METHODS
This report was based on a systematic literature review and economic modelling, supplemented by cost data. RESULTS - NUMBER AND QUALITY OF STUDIES: A reasonable number of randomised trials were found - three for docetaxel, six for gemcitabine, five for paclitaxel and 13 for vinorelbine. The quality of the trials was variable but good overall. There was a wide range of comparators. Some trials compared chemotherapy with best supportive care (BSC), which involves care that aims to control symptoms, with palliative radiotherapy if needed, but not to prolong life. Others compared the newer drugs against previous drugs or combinations. RESULTS - SUMMARY OF BENEFITS: The gains in duration of survival with the new drugs are modest - a few months - but worthwhile in a condition for which the untreated survival is only about 5 months. There are also gains in quality of life compared with BSC, because on balance the side-effects of some forms of chemotherapy have less effect on quality of life than the effects of uncontrolled spread of cancer. RESULTS - COSTS: The total cost to the NHS of using these new drugs in England and Wales might be about GBP 10 million per annum, but is subject to a number of factors. There would be non-financial constraints on any increase in chemotherapy for the next few years, such as staffing; the number of patients choosing to have the newer forms of chemotherapy is not yet known; and the costs of the drugs may fall, for example, as generic forms appear. RESULTS - COST PER LIFE-YEAR GAINED: The available data did not provide an entirely satisfactory basis for cost-effectiveness calculations. The main problem was the lack of direct comparisons of the new drugs. In order to strengthen the analysis, three different modelling approaches were used: pairwise comparisons using trial data; cost-minimisation analysis, as if all the new regimens were of equal efficacy; and cost-effectiveness analysis pooling the results of several trials with different comparators, giving indirect comparisons of the new drugs by using BSC as the common comparator. A number of different scenarios were explored through extensive sensitivity analysis in each model. Outcomes were expressed in incremental cost per life-year saved or incremental cost, versus BSC. There was insufficient evidence from which to derive cost per quality-adjusted life-year. In first-line treatment, vinorelbine, gemcitabine, and the lower-dose paclitaxel plus cisplatin combinations generally performed well against BSC under a range of different scenarios and especially when given as a maximum of 3 cycles. Incremental cost per life-year gained (LYG) versus BSC varied depending on scenario, but baseline figures based on trial data and protocols were: single-agent vinorelbine, pound 2194 per LYG; vinorelbine plus cisplatin, pound 5206; single-agent gemcitabine, pound 5690; gemcitabine plus cisplatin, pound 10,041; and paclitaxel plus cisplatin, pound 8537. In second-line chemotherapy, docetaxel gave a cost per LYG of pound 17,546, again well within the range usually accepted as cost-effective. However, in routine care, the impact of therapy would be regularly reviewed, and continuation would depend on response, side-effects, patient choice and clinical judgement. Chemotherapy would be stopped in non-responders, making chemotherapy more cost-effective. A 'real-life' scenario in which 60 per cent of patients receive only 1 or 2 cycles of chemotherapy gives much lower costs per LYG, with single-agent gemcitabine, single-agent vinorelbine, and paclitaxel plus platinum appearing to be cost-saving compared with BSC; the incremental cost of gemcitabine plus cisplatin would be pound 2478 per LYG, and of vinorelbine plus cisplatin, pound 2808. At the very least, gains in duration of survival were achieved without diminution of quality of life (at best, they improved quality) and with relatively low incremental cost. Comparisons among the individual drugs should be viewed with caution because they have had to be based on indirect comparisons. RESULTS - LIMITATIONS OF THE ANALYSIS: Each of the three models had limitations. The cost-effectiveness estimates from the pairwise comparisons were based on single studies. The cost-minimisation analysis assumed that the regimens have equal efficacy in practice. The cost-effectiveness analysis had to be based on pooling data from individual trials. The costs of BSC, inpatient stay and outpatient visits were from Scottish data. Median rather than mean data on duration of survival have been used in the analysis, because most of the trials reported only median data. Median survival and number of drug cycles were calculated by averaging across a number of studies, rather than being reliant on one particular study. The costs of the less expensive antiemetics cited in the trials were omitted. The use of more modern and costly antiemetics would have a modest detrimental effect on cost-effectiveness. In the absence of published data, an estimate was made of the cost of side-effects of chemotherapy, in particular hospital admissions, and applied to all the new regimens. In practice, admissions related to side-effects and their respective costs are likely to vary by regimen.
CONCLUSIONS
The new drugs for non-small-cell lung cancer extend life by only a few months compared with BSC, but appear to do so without net loss in quality of life and at a cost per LYG that is much lower than for many other NHS activities. Depending on assumptions used, these new drugs range from being cost-effective, as conventionally accepted, to being cost-saving. CONCLUSIONS - IMPLICATIONS OF THE NEWER DRUGS: One of the present constraints on chemotherapy is availability of inpatient beds. The advent of newer and gentler forms of chemotherapy given on an outpatient basis would not only overcome this, but it would allow more patients to be treated. This might apply particularly to older patients. The treatment of more patients would increase workload for oncologists, cancer nurses and pharmacists. The Government has already announced increased expenditure on staff for cancer care. The previously pessimistic attitudes to chemotherapy in non-small-cell lung cancer are changing in the wake of the newer agents, and this shift is likely to increase referral. CONCLUSIONS - NEED FOR FURTHER RESEARCH: Recent advances in chemotherapy are welcome, but their effects remain small for patients with non-small-cell lung cancer. Much more research is needed into better drugs, better combinations, new ways of assessing the likelihood of response and especially direct comparisons between the new regimens. This research would be aided by having a greater proportion of patients involved in trials, but there will be infrastructure implications of increased participation.

Review
BACKGROUND
Lung cancer remains a devastating disease with few effective treatment options. Recent developments in chemotherapy have led to cautious optimism. This paper reviews the evidence on the clinical and cost effectiveness of four of the new generation drugs for patients with lung cancer.
METHODS
A systematic review of randomised controlled trials (RCTs) identified from 11 electronic databases (including Medline, Cochrane library and Embase), reference lists and contact with experts and industry was performed to assess clinical effectiveness of paclitaxel, docetaxel, gemcitabine and vinorelbine. Clinical effectiveness was assessed using the outcomes of patient survival, quality of life, and adverse effects. Cost effectiveness was assessed by development of a costing model and presented as incremental cost per life year saved (LYS) compared with best supportive care (BSC).
RESULTS
Of the 33 RCTs included, five were judged to be of good quality, 10 of adequate quality, and 18 of poor quality. Gemcitabine, paclitaxel, and vinorelbine as first line treatment and docetaxel as second line treatment appear to be more beneficial for non-small cell lung cancer than BSC and older chemotherapy agents, increasing patient survival by 2-4 months against BSC and some comparator regimes. These gains in survival do not appear to be at the expense of quality of life. Survival gains were delivered at reasonable levels of incremental cost effectiveness for vinorelbine, vinorelbine with cisplatin, gemcitabine, gemcitabine with cisplatin, and paclitaxel with cisplatin regimens compared with BSC.
CONCLUSION
Although the clinical benefits of the new drugs appear relatively small, their benefit to patients with lung cancer appears to be worthwhile and cost effective.

Review
SECOND-LINE TREATMENT, PACLITAXEL (MEDIAN PROGRESSION-FREE SURVIVAL): The median progression-free survival in the paclitaxel arm was 3.5 months. This was significantly longer than the mitomycin control arm (1.6 months, p = 0.026). BREAST CANCER - SECOND-LINE TREATMENT, PACLITAXEL (MEDIAN OVERALL SURVIVAL): The median length of overall survival in the paclitaxel arm was 12.7 months, compared with 8.4 months in the mitomycin arm. BREAST CANCER - SECOND-LINE TREATMENT, PACLITAXEL (QUALITY OF LIFE): Quality of life was not reported. BREAST CANCER - SECOND-LINE TREATMENT, PACLITAXEL (ECONOMIC EVALUATION): The only economic evaluation that compared paclitaxel with control (mitomycin) was submitted in confidence and has been removed from this report. Six economic evaluations involved comparisons of paclitaxel and docetaxel, which are given below. BREAST CANCER - SECOND-LINE TREATMENT, DOCETAXEL: Four randomised controlled Phase III trials were identified: 303 Study, 304 Study, Scand and Bonneterre. A total of 1092 patients were included. One of these was a preliminary report of a study before completion of accrual (Bonneterre). Patients in the 303 Study had previously received chemotherapy involving alkylating agents; those in the other three had received anthracyclines. There were six economic evaluations on docetaxel. BREAST CANCER - SECOND-LINE TREATMENT, DOCETAXEL (QUALITY OF TRIALS): The 303 and 304 Studies were analysed on an intention to treat basis; the Scand trial excluded a single patient. The length of follow-up ranged from 11 months (Scand) to 23 months (303 Study). At least two-thirds of the participants in these trials had died. The Scand study recommended cross-over to alternate treatment on objective signs of disease progression. Patients crossing over in this way were violating the randomisation; however, no details were given concerning whether or not such patients were censored. In the economic analyses, there were no direct comparisons for the estimation of benefits. BREAST CANCER - SECOND-LINE TREATMENT, DOCETAXEL (MEDIAN PROGRESSION-FREE SURVIVAL): The median progression-free survival in the docetaxel arm ranged from 4.75 months (304 Study) to 7 months (Bonneterre). Patients in the docetaxel arms of the 304 and Scand studies had significantly longer progression-free survivals than controls (4.75 months versus 2.75 months, p = 0.001; 6.3 months versus 3 months, p = 0.001). BREAST CANCER - SECOND-LINE TREATMENT, DOCETAXEL (MEDIAN OVERALL SURVIVAL): The median overall survival in the docetaxel arm ranged from 10.4 months (Scand) to 15 months (303 Study). Patients in the docetaxel arms of the 304 Study survived for significantly longer than the mitomycin plus vinblastine arm (11.4 months versus 8.7 months, p = 0.03). BREAST CANCER - SECOND-LINE TREATMENT, DOCETAXEL (QUALITY OF LIFE): Quality of life was evaluated in two of the trials: the 303 and 304 Studies. There were no significant differences between docetaxel and control in either of these trials in terms of global health status, although differences were apparent on some subscales. These did not appear to follow a consistent pattern across the trials. BREAST CANCER - SECOND-LINE TREATMENT, DOCETAXEL (ECONOMIC EVALUATIONS): All six of these involved comparisons of paclitaxel and docetaxel, where the range of cost-utility ratios for incremental quality-adjusted life-years (QALYs) gained was pound 1990-pound 2431. In addition, three analyses compared docetaxel and vinorelbine. The cost-utility ratio for incremental QALYs gained was pound 14,050 in the only one of these carried out in the UK. OVARIAN CANCER - FIRST-LINE TREATMENT, PACLITAXEL: Four randomised controlled Phase III trials were identified: EORTC, TITGANZ, E1193 and CA139-278. (ABSTRACT TRUNCATED)
