A systematic review of chemotherapy trials in several tumour types was performed by The Swedish Council of Technology Assessment in Health Care (SBU). The procedures for the evaluation of the scientific literature are described separately (Acta Oncol 2001; 40: 155-65). This overview of the literature on aggressive, high grade non-Hodgkin's lymphoma (NHL), chiefly diffuse large B-cell lymphomas, is based on 111 scientific articles, including 35 randomised trials, 44 prospective studies and 11 retrospective studies, including totally 21,830 treated patients. ⋯ In patients not attaining complete remission after initial standard therapy, high-dose therapy with stem cell support may improve the response, but the impact on survival is not established. In patients refractory to initial standard therapy there is no evidence for a survival prolongation from high-dose therapy with stem cell support, although a subset of patients might benefit. For patients with chemosensitive relapse, salvage therapy followed by high-dose therapy with stem cell support is recommended, since this may result in prolonged survival.

A systematic review of chemotherapy trials in several tumour types was performed by The Swedish Council of Technology Assessment in Health Care (SBU). The procedures for the evaluation of the scientific literature are described separately (Acta Oncol 2001; 40: 155-65). This overview of the literature on chemotherapy in the treatment of gastric cancer is based on 153 scientific papers including one meta-analysis, 18 reviews, 60 randomised studies and 57 prospective studies. ⋯ In one study, quality-adjusted survival was estimated to a median of six months in the treated patients compared with two months in the controls. The quality of the literature addressing chemotherapy for gastric cancer is frequently poor with few properly designed randomised trials. In a number of randomised multi-centre adjuvant studies the inclusions rates are remarkably low, which reduces the scientific value of the studies.

This report by The Swedish Council on Technology Assessment in Health Care (SBU) reviews, classifies, and grades the scientific literature on cancer chemotherapy in some major tumour types, describes the practice of chemotherapy in Sweden, compares practice with scientific knowledge, and analyses the costs and cost-effectiveness of chemotherapy. The report is intended primarily for decision-makers at various levels, both practitioners and administrators. It is also of interest for the medical profession. ⋯ In those days, clinical treatment studies did not fulfil the current high quality requirements. Small life-prolonging effects of chemotherapy are sometimes very well documented in large, high quality scientific studies. Some of these s

A systematic review of chemotherapy trials in several tumour types was performed by The Swedish Council of Technology Assessment in Health Care (SBU). The procedures for the evaluation of the scientific literature are described separately (Acta Oncol 2001; 40: 155-65). This overview on chemotherapy for epithelial ovarian cancer is based on a total of 176 scientific reports. ⋯ Thus, in these patients treatment with a platinum/paclitaxel combination might be recommended. albeit based on limited data. In patients resistant to first-line therapy, a number of single agents induce tumour responses in the range of 10-30%. The literature does not permit general treatment recommendations in these patients, which are recommended to be included in controlled clinical trials.

A systematic review of chemotherapy trials in several tumour types was performed by The Swedish Council of Technology Assessment in Health Care (SBU). The procedures for evaluation the scientific literature are described separately (Acta Oncol 2001; 40: 155-65). This synthesis of the literature on chemotherapy for indolent non-Hodgkin's lymphoma (NHL), predominantly follicular lymphoma, is based on 108 scientific reports including 31 randomised studies, 38 prospective studies and 18 retrospective studies. ⋯ The impact of the novel treatment strategies including high-dose therapy on overall survival is still uncertain. A monoclonal antibody, rituximab, is a new active substance for patients with relapsed lymphoma. It can induce remissions also in chemoresistant patients.
