Randomized Controlled Trial Clinical Trial
Pulmonary toxicity with combined modality therapy for limited stage small-cell lung cancer.
To assess the pulmonary toxicity of radiation therapy combined with chemotherapy v chemotherapy alone, we reviewed the clinical course of 80 patients with limited stage small-cell lung cancer treated in a randomized prospective trial. Life-threatening pulmonary toxicity, defined as bilateral pulmonary infiltrates extending beyond radiation ports with symptoms requiring hospital admission, developed in 11 patients (28%) receiving combined modality therapy and in two (5%) receiving chemotherapy alone. Eight of these 13 patients died from pulmonary complications with no clinical evidence of tumor in five. ⋯ For the group treated with radiation therapy and chemotherapy, there was significantly less improvement after 6 or 12 months in the forced vital capacity (P less than .005) and FEV/1.0 second (P less than .005) than observed for the group treated with chemotherapy alone. Despite the increased incidence of pulmonary toxicity, overall survival favored the combined modality arm (P = .07). Enhanced local control and disease-free survival appeared to compensate for the initial increased pulmonary morbidity and mortality in the group with combined modality therapy.

Randomized Controlled Trial Comparative Study Clinical Trial
Combined modality therapy with radiotherapy, chemotherapy, and immunotherapy in limited small-cell carcinoma of the lung: a Phase III cancer and Leukemia Group B Study.
Patients with limited-stage small-cell carcinoma of the lung (SCCL) were randomly assigned to a four-drug chemotherapy program consisting of methotrexate, doxorubicin, cyclophosphamide, and CCNU (MACC) or to a regimen consisting of cyclophosphamide, CCNU, and vincristine alternated with Adriamycin (Adria Laboratories, Columbus, Ohio) and vincristine (CCV/AV). All patients received 4,500 cGy, in a split course, to the primary tumor, mediastinum, and supraclavicular lymph node drainage areas and 3,000 cGy to the whole brain. After four cycles of chemotherapy, patients were randomly assigned to chemotherapy plus methanol extractable residue of BCG (MER-BCG) or no MER-BCG. ⋯ Immunotherapy with MER-BCG did not prolong the time to disease progression or improve survival. Women had a greater chance of achieving a complete remission independent of performance status. There was a complex interaction between sex and the chemotherapy regimens that may have important implications for the design and stratification of future trials in SCCL.

Randomized Controlled Trial Comparative Study Clinical Trial
Neoadjuvant chemotherapy for osteogenic sarcoma: results of a Cooperative German/Austrian study.
From December 1979 to August 1982 158 patients were registered for an adjuvant chemotherapy (CT) study COSS -80. To compare the effect of cisplatin (CPL) to that of the drug combination bleomycin, cyclophosphamide, and dactinomycin (BCD), patients were randomized to receive either drug(s) within a course of sequential multidrug CT including doxorubicin and high-dose methotrexate (HDMTX). Definite surgery was done 10-18 weeks after the start of CT. ⋯ After exclusion of 42 patients because of some deviation in history and/or management, 86 (74%) of 116 patients actually were CDF with a 30-month calculated CDF-rate of 68%. There was no difference in CDF rates in the patients receiving BCD versus CPL or receiving interferon versus no interferon. Whereas, in comparison to the previous study COSS -77, the over-all increase in CDF rate does not reach statistical significance, it does, however, for the younger (less than or equal to 12 years) and for male patients, which is assumed to be the effect of increasing the methotrexate dose from 6 to 12 g/m2 in the COSS -80 study.
