The role of second-line chemotherapy for the treatment of patients with non-small cell lung cancer (NSCLC) who have relapsed or failed to respond to first-line treatment was unclear.

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.

Anthracyclines are essential for the treatment of the children with cancer. We performed a systematic review to evaluate the existing evidence of the frequency and risk factors of anthracycline-induced clinical heart failure (A-CHF) in children.

To evaluate the chemotherapeutic options for women with recurrent epithelial ovarian cancer who have received platinum-based chemotherapy.

The aim of this study was to determine the optimal postoperative chemotherapy regimen for women with newly diagnosed stage II, III (micro or macro), or IV epithelial ovarian cancer.

No standard systemic adjuvant therapy has been proven to increase overall survival in melanoma patients. The effect of interferon alfa (IFNalpha) as a single agent or in combination has been widely explored in clinical trials. The purpose of this study was to assess the benefit of IFNalpha therapy in malignant melanoma.

A rapid and systematic review of the effectiveness and cost-effectiveness of temozolomide in the treatment of recurrent malignant glioma was commissioned by the NHS HTA Programme on behalf of NICE. The full report has been published elsewhere. This paper summarizes the results for the effectiveness of temozolomide in people with recurrent glioblastoma multiforme and anaplastic astrocytoma. The review was conducted using standard systematic review methodology involving a systematic literature search, quality assessment of included studies with systematic data extraction and data synthesis. One randomized controlled trial and four uncontrolled studies were identified for inclusion. The key results were that temozolomide may increase progression-free survival but has no significant impact on overall length of survival. The main effect from temozolomide may have been in those patients who had not received any prior chemotherapy regimens, however further randomized controlled trials are required to confirm this suggestion. Temozolomide appears to produce few serious adverse effects and may also have a positive impact on health-related quality of life. Overall the evidence-base is weak and few strong conclusions can be drawn regarding the effectiveness of temozolomide. Large, well-designed randomized controlled trails conducted in a wider patient population are needed.

Ovarian cancer is the most common gynaecological cancer with an annual incidence of 21.6 per 100,000 in England and Wales. Due to the often asymptomatic nature of the early stages of the disease, most cases are not detected until the advanced stages. Consequently, the prognosis after diagnosis is poor and the 5-year survival rate in the UK is only about 30%. Current recommendations suggest that first-line chemotherapy for ovarian cancer should involve paclitaxel and platinum (Pt)-based therapy (cisplatin/ carboplatin), however, most patients develop resistant or refractory disease and require second-line therapy. Patients may respond to re-challenge with Pt-agents if the treatment-free interval is > 6 months, but an alternative is often required. Topotecan is one of six drugs currently licensed in the UK for second-line therapy, and recent reviews suggest that it has modest efficacy in the treatment of advanced disease and performs favourably against paclitaxel. However, these reviews are based on a limited number of reports mainly consisting of non-randomised Phase I and II studies.

The role of second-line chemotherapy for the treatment of patients with non-small cell lung cancer (NSCLC) who have relapsed or failed to respond to first-line treatment was unclear.

The US National Cancer Institute alert in February, 1999, stated that concomitant chemotherapy and radiotherapy should be considered for all patients with cervical cancer. Our aim was to review the effects of chemoradiotherapy on overall and progression-free survival, local and distant control, and acute and late toxicity in patients with cervical cancer.

Epoetin treatment offers an attractive but costly alternative to red blood cell transfusion for managing anemia associated with cancer therapy. The goal of this review is to facilitate more efficient use of epoetin by 1) quantifying the effects of epoetin on the likelihood of transfusion and on quality of life in patients with cancer treatment-related anemia and 2) evaluating whether outcomes are superior when epoetin treatment is initiated at higher hemoglobin thresholds. Two independent reviewers followed a prospective protocol for identifying studies. Outcomes data were combined with the use of a random-effects meta-analysis model. Double-blind, randomized, controlled trials that minimized patient exclusions were defined as higher quality for sensitivity analysis; randomized but unblinded trials and trials with excessive exclusions were included in the meta-analysis but were defined as lower quality. Twenty-two trials (n = 1927) met inclusion criteria, and 12 (n = 1390) could be combined for estimation of odds of transfusion. Epoetin decreased the percentage of patients transfused by 9%-45% in adults with mean baseline hemoglobin concentrations of 10 g/dL or less (seven trials; n = 1080), by 7%-47% in those with hemoglobin concentrations greater than 10 g/dL but less than 12 g/dL (seven trials; n = 431), and by 7%-39% in those with hemoglobin concentrations of 12 g/dL or higher (five trials; n = 308). In sensitivity analysis, the combined odds ratio for transfusion in epoetin-treated patients as compared with controls was 0.45 (95% confidence interval [CI] = 0.33 to 0.62) in higher quality studies and 0.14 (95% CI = 0.06 to 0.31) in lower quality studies. The number of patients needed to treat to prevent one transfusion is 4.4 for all studies, 5.2 for higher quality studies, and 2.6 for lower quality studies. Only studies with mean baseline hemoglobin concentrations of 10 g/dL or less reported statistically significant effects of epoetin treatment on quality of life; quality-of-life data were insufficient for meta-analysis. No studies addressed epoetin's effects on anemia-related symptoms. We conclude that epoetin reduces the odds of transfusion for cancer patients undergoing therapy. Evidence is insufficient to determine whether initiating epoetin earlier spares more patients from transfusion or results in better quality of life than waiting until hemoglobin concentrations decline to nearly 10 g/dL.

To quantify the antiemetic efficacy and adverse effects of cannabis used for sickness induced by chemotherapy.

In order to clarify the role of mitomycin (MMC) in the treatment of NSCLC, we performed a systematic review of the literature and qualitatively assessed the selected studies using the ELCWP and Chalmers scales. 5 trials (202 patients) assessed the activity of MMC as single-agent chemotherapy in NSCLC. The overall response rate was 25% (95% Cl 19-31). In 10 randomized phase III trials (1769 patients), we studied the role of MMC in combination therapy. A meta-analysis, based on the available published data, failed to show any survival advantage of the MMC containing regimens (hazard ratio = 0.95; 95% Cl 0.83-1.10). Finally, 4 eligible trials (139 patients) assessed the activity of MMC regimens as salvage therapy, 3 in combination with vindesine and one with cisplatin and vinblastine. The overall response rate for the MMC-vindesine regimen was 10.5% (95% Cl 1.7-19.4). In conclusion, MMC is an active drug for NSCLC but does not improve survival when combined with other active drugs, particularly cisplatin. Its use for salvage therapy appears to be associated with marginal activity only.

Patients with cancer are frequently treated with anticoagulants, including heparins, to treat or to prevent thrombosis. Recent randomized trials that compared low molecular weight heparin to unfractionated heparin for the treatment of deep vein thrombosis have indicated that heparins affect survival of patients with cancer. Experimental studies support the hypothesis that cancer progression can be influenced by heparins, but results of these studies are not conclusive. Heparins are negatively charged polysaccharides that can bind to a wide range of proteins and molecules and affect their activity. As a consequence, heparins have a wide variety of biological activities other than their anticoagulant effects, which may interfere with the malignant process. In the present systematic review, we critically evaluate experimental studies in which heparins have been tested as anti-cancer drugs. All animal studies, published between 1960 and 1999, that report effects of heparins on growth of subcutaneously implanted tumors, spontaneous metastasis or experimentally induced metastasis are reviewed. In addition, we discuss mechanisms by which heparins potentially exert their activity on various steps in cancer progression and malignancy related processes. It is shown that heparins can affect proliferation, migration, and invasion of cancer cells in various ways and that heparins can interfere with adherence of cancer cells to vascular endothelium. Moreover, heparins can affect the immune system and have both inhibitory and stimulatory effects on angiogenesis. Because of the wide variety of activities of heparins, it is concluded that the ultimate effect of heparin treatment on cancer progression is uncertain.

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)

The "Standards, Options and Recommendations" (SOR) project, started in 1993, is a collaboration between the Federation of the French Cancer Centres (FNCLCC), the 20 French Cancer Centres and specialists from French Public Universities, General Hospitals and Private Clinics. The main objective is the development of clinical practice guidelines to improve the quality of health care and outcome for cancer patients. The methodology is based on literature systematic review and critical appraisal by a multidisciplinary group of experts, with feedback from specialists in cancer care delivery.

Despite being the subject of clinical research for more than 20 years, the role of anthracyclines in the treatment of ovarian cancer is still undefined. This review summarizes and re-evaluates the published data with the anthracylines doxorubicin, epirubicin (4'-epi-doxorubicin), daunorubicin (idarubicin), aclarubicin, and pirarubicin. The studies were identified by MEDLINE-search and analysis of the references cited in the identified articles and reviews covering this subject. First-line therapy: Studies from the 70ies could demonstrate that doxorubicin was as effective as alkylating agents. The combination of anthracylines and alkylating agents provided superior results compared with alkylating agents alone. Further improvements were gained by the introduction of platinum-anthracyline combination regimens. Doxorubicin and epirubicin showed comparable activity when combined with platinum. The comparison between platinum-anthracyline containing combination regimens with platinum based regimens without anthracylines did not provide definitive answers. The majority of studies (with relatively small patient numbers) did not reveal any significant benefit for the anthracyline containing regimens. In contrast, four meta-analyses combining several studies showed a significant improvement when anthracylines were added to platinum based regimens. This question came up again when standard treatment for ovarian cancer was modified by the introduction of paclitaxel in the mid 90ies. Currently, two randomized large intergroup trials evaluate the role of anthracyclines in combination with platinum and paclitaxel. Results from these studies will be available in 1-2 years and might help to describe the role for anthracyclines in ovarian cancer treatment more precisely. Until then, the use of anthracyclines in upfront chemotherapy of ovarian cancer outside of clinical trials cannot be recommended. 2n-line therapy: The anthracyclines doxorubicin and epirubicin are among the most active single agents for the treatment of platinum refractory ovarian cancer. Both agents achieved tumor responses in up to 25%. Preliminary data suggest, that the combination with paclitaxel could increase efficacy. No such effect was reported for any other combination. In contrast, single agent anthracyclines cannot be recommended for treatment of platinum sensitive tumors. However, combining anthracyclines with platinum resulted in remarkable response rates of more than 50% of patients with platinum sensitive tumors. Only few studies report the use of anthracylines after platinum and paclitaxel containing first-line chemotherapy. Preliminary data from small studies (40 patients) suggest that anthracyclines showed activity in this particular population. No final conclusions can be drawn. There is a need for developing effective 2nd-line therapies for patients failing platinum and paclitaxel combination regimens. Among others, anthracyclines should be evaluated in this clinical setting.

Treatment of cancer with chemotherapy is becoming increasingly more effective but is associated with short and long-term side effects. Oral side effects remain a major source of illness despite the use of a variety of agents to prevent them.
