Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Adjuvant CMFVP versus tamoxifen versus concurrent CMFVP and tamoxifen for postmenopausal, node-positive, and estrogen receptor-positive breast cancer patients: a Southwest Oncology Group study.
To compare chemohormonal therapy, chemotherapy alone, and hormonal therapy alone in postmenopausal patients with estrogen receptor (ER)-positive operable breast cancer and positive axillary nodes with respect to survival and disease-free survival (DFS). ⋯ CMFVP chemotherapy, either alone or in combination with tamoxifen, has not been shown to be superior to tamoxifen alone in the treatment of postmenopausal women with node-positive, ER-positive, operable breast cancer.

Randomized Controlled Trial Multicenter Study Clinical Trial
Treatment of children with stages II to IV anaplastic Wilms' tumor: a report from the National Wilms' Tumor Study Group.
To evaluate the effect of the combination of vincristine, dactinomycin, and doxorubicin with (regimen J) or without (regimen DD-RT) cyclophosphamide on the relapse-free survival of children with stages II to IV Wilms' tumor and focal or diffuse anaplasia. ⋯ We conclude that children with focal anaplasia have an excellent prognosis when treated with vincristine, doxorubicin, and dactinomycin. The addition of cyclophosphamide to the three-drug treatment regimen improved the 4-year relapse-free survival rate of children with stage II to IV diffuse anaplasia. This result suggests that further intensification of the treatment regimen for children with diffuse anaplasia may result in an additional improvement in prognosis.

We conducted a phase I trial of irinotecan (CPT-11), a topoisomerase I inhibitor, combined with etoposide, a topoisomerase II inhibitor, and recombinant human granulocyte colony-stimulating factor (rhG-CSF) support because of the overlapping neutrophil toxicity of both drugs. The aim was to determine the maximum-tolerated dose of CPT-11 combined with a fixed dose of etoposide in patients with advanced lung cancer, as well as the dose-limiting toxicities of this combination. ⋯ The combination of CPT-11 and etoposide with rhG-CSF support seems to be active against lung cancer, especially SCLC, with acceptable toxicity. The recommended dose for phase II studies in previously untreated patients is 80 mg/m2 of CPT-11 (days 1, 8, and 15) and 80 mg/m2 of etoposide (days 1 to 3) plus 2 micrograms/kg of rhG-CSF (days 4 to 21, except when CPT-11 is given). In addition, 70 mg/m2 of CPT-11 appears to be the appropriate dose for previously treated patients receiving this regimen.

Randomized Controlled Trial Clinical Trial
Blood transfusion-modulated tumor recurrence: first results of a randomized study of autologous versus allogeneic blood transfusion in colorectal cancer surgery.
Allogeneic blood transfusions have reportedly been associated with a poor prognosis in patients with curatively resected cancer. To control for immunosuppression induced by a speculatively causal allogeneic blood transfusion, we designed a randomized study in which the control group received autologous blood transfusions not related to any condition of immunosuppression. ⋯ As indicated by these first results, the blood transfusion modality has a significant effect on tumor recurrence after surgical treatment of colorectal cancer. A change in the practice of blood transfusion might thus potentially surpass the impact of any recent adjuvant treatment strategies.
