Combination v. sequential therapy with melphalan, 5-fluorouracil and methotrexate for advanced ovarian cancer.

The results of a national clinical trial to compare combination and sequential chemotherapy for stage III or IV ovarian cancer are reported. Of the 253 patients from 16 centres across Canada who were admitted to the trial 13 were excluded from the analysis. All the patients were observed for 2 to 5 years from entry into the trial. There were no differences in response to therapy or in survival between the patients treated with melphalan followed by 5-fluorouracil and then by methotrexate in high dosage and the patients treated with the same agents in combination. Patients with minimal residual disease after resection of stage III ovarian cancer had a good prognosis. Other favourable prognostic factors were age (less than 55 years), performance status (90% or 100% on the Karnofsky scale) and histologic grade of the tumour.

Oral administration of BCG as an adjuvant to surgical treatment of carcinoma of the bronchus.

A controlled clinical trial of the value of bacille Calmette--Guérin (BCG) vaccine given orally to patients with resectable carcinoma of the lung was conducted in 18 centres across Canada. A total of 308 patients were included in the analysis, 155 in the BCG group and 153 in the control group. The two groups were similar at the time of admission to the trial. BCG (120 mg) was given orally at weekly intervals for 1 month, every 2 weeks up to 3 months and then every 3 months until the total duration of therapy was 18 months. Over a 3- to 5-year follow-up period after the operation there was no difference in survival between the two groups, the proportion alive at 2 years being 61% in the BCG group and 58% in the control group. There was also no evidence of differences in the time to the detection of recurrent or metastatic disease or in the distribution of such disease. An analysis of prognostic factors confirmed the poor survival associated with histologically confirmed lymph node involvement. It may be concluded that no favourable effect from the oral administration of BCG was demonstrated.
