The aim of this study was to measure the proportion and characteristics of complementary therapy (CT) users among female breast cancer patients receiving conventional treatment. 473 women who had received surgical intervention for breast cancer in the year of diagnosis were sent a questionnaire for completion, and 242 responded. CT had been used by 16.5% after cancer diagnosis, only 8.7% before. The most commonly used CTs were homeopathy, manual healing method, herbalism and acupuncture. ⋯ Only a minority was searching for psychological support. 24 users were satisfied with these treatments, and two-thirds would suggest them. Users were significantly younger, more educated, and previous users of CTs than non-users. Adjusting each variable for the effect of the others, only previous use had an independent effect on increasing the probability of being users after cancer diagnosis.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Randomised double-blind study comparing tropisetron alone and in combination with dexamethasone in the prevention of acute and delayed cisplatin-induced emesis.
In a randomised, double-blind and parallel-design multicentre study, 282 chemotherapy-naive cancer patients received tropisetron 5 mg intravenously (i.v.) before high-dose cisplatin on day 1, and oral tropisetron 5 mg daily on days 2-6, in combination with either placebo (n = 143) or dexamethasone (n = 135), given i.v. on day 1 and orally on days 2-6. Complete protection from acute vomiting/nausea was achieved in 76.3%/79.3% of patients receiving the combination and in 55.2%/61.5% of those receiving tropisetron alone. Complete protection on days 2-6 from delayed vomiting/nausea was obtained in 60%/60% and 39.2%/40.6%, respectively. Tropisetron in combination with dexamethasone is safe and more effective than tropisetron alone in the prevention of both acute and delayed cisplatin-induced emesis.

Randomized Controlled Trial Multicenter Study Clinical Trial
Prophylactic cranial irradiation is indicated following complete response to induction therapy in small cell lung cancer: results of a multicentre randomised trial. United Kingdom Coordinating Committee for Cancer Research (UKCCCR) and the European Organization for Research and Treatment of Cancer (EORTC)
Prophylactic cranial irradiation (PCI) reduces the risk of cranial metastasis in small cell lung cancer (SCLC), but the magnitude and value of this reduction, the risks of radiation morbidity and whether PCI influences survival are unclear. We conducted a randomised trial in patients with limited-stage SCLC who had had a complete response to induction therapy. Initially, patients were randomised equally to (1) PCI 36 Gy in 18 daily fractions, (2) PCI 24 Gy in 12 fractions and (3) no PCI; subsequently, to increase the rate of accrual, randomisation was to clinicians' choice of PCI regimen versus no PCI (at a 3:2 ratio). ⋯ PCI can safely reduce the risk of brain metastases. Further research is needed to define optimal dose and fractionation and to clarify the effect on survival. Patients with SCLC achieving a complete response to induction therapy should be offered PCI.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
A double-blind crossover study comparing prophylactic intravenous granisetron alone or in combination with dexamethasone as antiemetic treatment in controlling nausea and vomiting associated with chemotherapy.
The efficacies of granisetron plus dexamethasone and granisetron alone in controlling nausea and vomiting during two consecutive cycles of moderately emetogenic chemotherapy given for up to 5 days were compared in a two-centre, randomised, double-blind, placebo-controlled crossover study. In all, 110 evaluable patients received either dexamethasone, 20 mg i.v., or matching placebo, plus open-label granisetron, 3 mg i.v., given on each chemotherapy day. At cycle 2, patients crossed over to the alternative treatment; 72 patients completed the crossover. ⋯ Adverse events tended to be minor, with asthenia and insomnia the most common. Of those patients who expressed a preference, 67% preferred granisetron plus dexamethasone (P < 0.05). A single dose of dexamethasone added to granisetron thus enhances the efficacy of granisetron alone in preventing nausea and vomiting after moderately emetogenic chemotherapy.

The four national paediatric cancer clinical trials organisations in the United States--the Children's Cancer Group, the National Wilms' Tumor Study Group, the Intergroup Rhabdomyosarcoma Study Group and the Pediatric Oncology Group--were formed in 1955, 1969, 1972 and 1979, respectively. Together, the Children's Cancer Group and Pediatric Oncology Group serve as a national registry of nearly all childhood cancers in the United States, provide a national network of communication for researchers, care providers and families of paediatric patients with malignant disease and conduct laboratory investigations and clinical trials of new treatments of cancers in infants, children, adolescents and young adults. Nearly 95% of patients with cancer in the United States who are below 15 years of age are registered by the Children's Cancer Group and the Pediatric Oncology Group and more than half of American children with cancer are entered into at least one trial by a paediatric group. ⋯ By the year 2000, the overall cure rate for United States children and adolescents with cancer should exceed 85%. To reach this goal, the way forward will depend on international collaboration, implementation of global harmonisation, prevention of the erosion of biomedical research and clinical trials by the managed health care industry, increased public and private financial support and continued recruitment into paediatric oncology of brilliant and dedicated young investigators. The specific challenges ahead include: (1) transferring the knowledge, methodologies and technologies to countries that are less fortunate; (2) conducting multinational clinical trials in conjunction with paediatric cooperative groups in other countries; (3) accessing older adolescent patients who currently do not participate in cooperative group trials; (4) merging clinical trials by adult collaborative groups that overlap with the paediatric groups, as in acute lymphoblastic leukaemia, acute myelogenous leukaemia, Hodgkin's disease, osteosarcoma and germ cell tumours; (5) establishing a stable source of funding for national and international cooperative paediatric cancer clinical trials; (6) creating an informatics system that can link paediatric cooperative group operation centres around the world, and the institutions within each collaborative group; and (7) securing the support of the insurance industry and government in covering clinical trials.
