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 synthesis of the literature on chemotherapy for B-cell chronic lymphocytic leukaemia (B-CLL) is based on data from 20 randomised controlled trials and one meta-analysis. ⋯ Thus, transplantation remains experimental; more patients and a longer follow-up are needed to assess if cure can be achieved. In the future an individual risk-adapted therapy will be required. The clinical heterogeneity of the disease has pointed to the necessity of new predictors for prognosis evaluated in prospective trials.

The procedures for the evaluation of the scientific literature are described separately (Acta Oncol 2001; 40: 155-65). This synthesis of the literature on chemotherapy for Hodgkin's disease (HD) is based on 113 scientific reports including four meta-analyses, 44 randomised studies, 18 prospective studies and 40 retrospective studies. ⋯ However, this use is based on data from uncontrolled or small controlled studies, not being fully convincing with respect to effect on survival. Persistent side-effects of treatment are common among long-term survivors, although most patients have an apparently normal life. The relative contributions of chemotherapy and radiotherapy to the persistent effects are not well documented.

The procedures for the evaluation of the scientific literature are described separately (Acta Oncol 2001; 40: 155-65). This synthesis of the literature on chemotherapy for urothelial bladder cancer is based on 234 scientific reports including two meta-analyses, 75 randomised studies and 143 other prospective studies, and totally comprising 31,974 patients. ⋯ With the exception of one randomised study, there are no conclusive data on possible survival benefit for patients with muscle-invasive bladder cancer treated with neoadjuvant chemotherapy prior to cystectomy or radiotherapy. Although the results from use of adjuvant chemotherapy after surgery or curative radiotherapy obtained are promising, the small studies performed lack statistical power and, hence, there is insufficient data to make any conclusion regarding a possible survival benefit from adjuvant chemotherapy. A growing body of data indicate that bladder preservation can be achieved by multi-modality approach in selected patients and that survival in these is similar to that seen after radical cystectomy, but randomised trials are still lacking.

Randomized Controlled Trial Comparative Study Clinical Trial
Morphine or oxycodone in cancer pain?
Oxycodone is an opioid analgesic that closely resembles morphine. Oxymorphone, the active metabolite of oxycodone, is formed in a reaction catalyzed by CYP2D6, which is under polymorphic genetic control. The role of oxymorphone in the analgesic effect of oxycodone is not yet clear. ⋯ Liver dysfunction affected selectively either oxycodone or morphine metabolism. Three patients with markedly aberrant plasma opioid concentrations are presented. Significant individual variation in morphine and oxycodone metabolism may account for abnormal responses during treatment of chronic cancer pain.

Randomized Controlled Trial Clinical Trial
Treatment of breast-cancer-related lymphedema with or without manual lymphatic drainage--a randomized study.
A prospective randomized study was carried out to investigate whether the addition of manual lymphatic drainage (MLD) to the standard therapy could improve treatment outcome in women with lymphedema of the ipsilateral arm after breast cancer treatment. Forty-two patients were randomly assigned to receive standard therapy or standard therapy plus MLD 8 times in 2 weeks and training in self-massage. ⋯ The patients were followed-up for a total of 12 months. The study showed that both groups obtained a significant reduction in edema and that MLD did not contribute significantly to reduce edema volume.
