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.

Randomized Controlled Trial Comparative Study Clinical Trial
Randomized trial of opioids versus tricyclic antidepressants for radiation-induced mucositis pain in head and neck cancer.
Patients who receive radiotherapy for head and neck cancer are likely to develop painful mucositis. The pain is characterized by a burning or stinging sensation similar to neuropathic pain sensations. The purpose of the present study was to compare the analgesic effect of a tricyclic antidepressant (TC), commonly used in the treatment of neuropathic pain, with the effect of opioids on radiation-induced mucositis pain. ⋯ Higher pain scores in the TC arm, but not in the opioid arm, were significantly correlated with higher BDI scores. Some head and neck cancer patients with radiation-induced nucositis pain may have sufficient pain control on TC alone. This might be useful in patients with relative counter-indications to opioid treatment.

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 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.

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 for non-small cell lung cancer (NSCLC) is based on 53 scientific publications including six meta-analyses based on 65 prospective randomised trials comprising 15,607 patients and an additional 32 prospective randomised studies including 8,902 patients. ⋯ The superiority of induction chemotherapy plus surgery compared with combined chemotherapy and radical irradiation has not been proven in a randomised trial but currently such studies are under way. In the adjuvant setting, published data suggest that cisplatin-based chemotherapy after radical surgery may increase five-year survival from around 50% by a further 5% but the confidence interval for this estimate is too wide for firm conclusions. Large-scale prospective randomised trials are under way to resolve this important issue and adjuvant chemotherapy is, thus, not recommended for routine treatment.
