Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Etoposide combined with cyclophosphamide plus vincristine compared with doxorubicin plus cyclophosphamide plus vincristine and with high-dose cyclophosphamide plus vincristine in the treatment of small-cell carcinoma of the lung: a randomized trial of the Bristol Lung Cancer Study Group.
A total of 353 patients with previously untreated small-cell lung cancer (SCLC) were accrued in this multicenter trial. Patients were randomly assigned to receive one of the following three regimens: cyclophosphamide 1,000 mg/m2 intravenously (IV) day 1, vincristine 1.4 mg/m2 IV day 1, and etoposide 50 mg/m2 IV day 1, followed by etoposide 100 mg/m2/day orally days 2 through 5 (CEV); cyclophosphamide 1,000 mg/m2 IV day 1, vincristine 1.4 mg/m2 IV day 1, and doxorubicin 50 mg/m2 IV day 1 (CAV); cyclophosphamide 2,000 mg/m2 day 1 and vincristine 1.4 mg/m2 IV day 1 (CV). Cycles were repeated every 3 weeks. ⋯ Cardiotoxicity only occurred in the CAV group (P = .05). The addition of etoposide to the CV regimen resulted in significantly longer response duration and survival without increased toxicity. Similarly, the substitution of etoposide for the doxorubicin in the CAV regimen was associated with prolonged survival and reduced cardiotoxicity.

Randomized Controlled Trial Comparative Study Clinical Trial
Controlling delayed vomiting: double-blind, randomized trial comparing placebo, dexamethasone alone, and metoclopramide plus dexamethasone in patients receiving cisplatin.
The majority of patients receiving cisplatin at a dose of 120 mg/m2 experience delayed nausea and vomiting occurring between 24 and 120 hours after chemotherapy administration. Ninety-one patients who were receiving cisplatin (120 mg/m2) as initial chemotherapy were entered into this double-blind trial. All patients received intravenous (IV) metoclopramide, dexamethasone, and lorazepam for the control of acute emesis during the period from 0 to 24 hours after cisplatin. ⋯ Scores assessing the severity of delayed nausea and vomiting were consistently worse in individuals receiving placebo. The incidences of sleepiness, restlessness, heartburn, hiccoughs, loose bowel movements, insomnia, and acute dystonic reactions did not differ significantly among the three regimens and were mild and self-limited. The two-drug combination of oral metoclopramide plus dexamethasone is well tolerated, safe, and more effective than dexamethasone alone or placebo in controlling delayed vomiting following cisplatin.

Randomized Controlled Trial Comparative Study Clinical Trial
Combined modality therapy for advanced Hodgkin's disease: 15-year follow-up data.
From 1969 through 1982, 184 patients with advanced Hodgkin's disease (HD) were treated with combined modality therapy (CMT) at Yale University. The data were reanalyzed in November 1986, with a mean follow-up of 10 years. The patient population consisted of 102 newly diagnosed stages IIIB and IV patients, and 82 patients who had relapsed after initial radical radiotherapy. ⋯ No improvement resulted from the use of MOPP-ABVD in the poor-risk patients. These results compare favorably with those recently published by the National Cancer Institute (NCI). CMT resulted in an approximate 20% improvement in survival with no increase in second malignancies when compared with chemotherapy alone.

Randomized Controlled Trial Clinical Trial
Neoadjuvant chemotherapy of osteosarcoma: results of a randomized cooperative trial (COSS-82) with salvage chemotherapy based on histological tumor response.
Following observation of the predictive value of the histologic extent of tumor cell destruction after preoperative chemotherapy for metastasis-free survival (MFS) in osteosarcoma, a randomized study was undertaken with the aim of (1) sparing some patients the unpleasant side effects of highly toxic drugs like doxorubicin (DOX) and cisplatin (CPDD) by administering these drugs postoperatively only after poor response with a milder preoperative regimen, and (2) improving the prognosis of patients responding poorly to the initial treatment by use of a salvage chemotherapy postoperatively. The available patients were divided into two groups. Those in the study arm received a preoperative chemotherapy consisting of high-dose methotrexate (HDMTX) and the triple drug combination of bleomycin, cyclophosphamide, and dactinomycin (BCD) and were switched to DOX/CPDD postoperatively in case of poor response. ⋯ The actuarial 4-year MFS rate of poor responders after salvage chemotherapy also was poorest in the study arm (41%); it was unchanged in the control arm (53%) as compared with that of poor responders from the COSS-80 study without salvage chemotherapy (52%). The actuarial 4-year MFS rate of good responders was 73% in the study arm, 79% in the control arm, and not significantly different from that of the COSS-80 study (84%), although postoperative chemotherapy of good responders had been markedly shortened as compared with the COSS-80 study. The actuarial 4-year MFS rate of the study arm as a whole was inferior to that of the control arm (49% v 68%; P less than .1) and also inferior to the COSS-80 study (68%; P less than .01), indicating a failure of the employed salvage strategy in general and especially of the effort to restrict the use of the very effective but highly toxic drugs DOX and CPDD to patients resistant to a less toxic initial treatment.

Randomized Controlled Trial Clinical Trial
Adjuvant chemotherapy for osteosarcoma: a randomized prospective trial.
To determine the role of chemotherapy in the multidisciplinary treatment of patients with osteosarcoma, a randomized prospective trial of postoperative adjuvant chemotherapy was begun in 1981. Fifty-nine patients with nonmetastatic classic intramedullary osteosarcoma were randomized; 32 received postoperative adjuvant chemotherapy consisting of high-dose methotrexate, Adriamycin (Adria Laboratories, Columbus, OH), and BCD (bleomycin, cytoxan, actinomycin D), and 27 patients received no adjuvant chemotherapy. ⋯ In addition, there was no difference in the less than 20% disease-free or overall survival of patients treated in the 1970s who did not receive chemotherapy, as compared with the concurrent nontreatment controls. Therefore, with identical staging procedures, uniform surgical management, and standard pathologic evaluation, postoperative adjuvant chemotherapy definitely improves disease-free and overall survival in patients with osteosarcoma.
