Melphalan versus adriamycin in the treatment of advanced carcinoma of the ovary.

The therapeutic effects of adriamycin and of melphalan in patients with advanced carcinoma of the ovary were tested in a prospective randomized study. Complete and partial remission occurred in eight of 19 patients treated with adriamycin and in four of 20 patients given melphalan. The difference, however, is not statistically significant. The median duration of complete and partial remissions was slightly longer after treatment with melphalan than with adriamycin. The number of cycles required to produce the initial regression state was less in the patients in the group given adriamycin as compared with those in the group treated with melphalan. No cross resistance was observed between the two drugs. These data indicate that, in patients with carcinoma of the ovary, the therapeutic efficacy of adriamycin is competitive with that of the most effective conventional agents, such as melphalan.

Combination chemotherapy and radiotherapy in non-Hodgkin's lymphomata.

The results obtained with intensive chemotherapy and intensive chemotherapy plus radiotherapy in non-Hodgkin's lymphomata are reported. A quintuple drug regimen (mechloretamine, adriamycin, bleomycin, vincristine and prednisone) in histiocytic lymphomata (Stage III and IV) yielded complete remissions in 53% and complete plus partial remissions in 77%. These figures were 44% and 64% respectively in lymphocytic lymphoma. In Stage III complete responders after combination chemotherapy were subsequently irradiated (involved field irradiation). The median duration of complete remission after completion of radiotherapy was 9-5 months in histiocytic and 12-0 months in lymphocytic lymphomata. At 2 years actuarial survival in Stage III and IV was better in patients with the lymphocytic type and with nodular pattern than with histiocytic and diffuse patterns. A more recent trial compares, in Stage IV patients, cyclophosphamide, vincristine and prednisone (CVP) versus adriamycin, bleomycin and prednisone (ABP). Although the number of evaluable patients is still limited, there appears to be no difference in the response rate between CVP and ABP. In Stages I and II, 6 cycles of CVP were given as adjuvant treatment after radiotherapy. At the present moment, there is no statistical difference in the relapse rate between the group of patients treated with radiotherapy alone and that with radiotherapy plus CVP.

Malignant lymphomas of Waldeyer's ring: natural history and survival after radiotherapy.

The natural history of 292 consecutive cases of reticulum cell sarcoma and lymphosarcoma of Waldeyer's ring and the survival rate after radiotherapy are reported. In our institute since 1928 from 30 to 35% of pharyngeal neoplasms have been lymphomas, and of these 55% have been reticulum cell sarcomas, 21% lymphosarcomas, and 1% Hodgkin's disease. This high incidence may probably be ascribed to the fact that in all malignant lymphomas, irrespective of the clinical presentation, a systematic biopsy of the whole Waldeyer's ring was carried out. Pharyngeal lymphomas were confined to Waldeyer's ring in 19.6% of cases, with initial spread to contiguous cervical nodes in 43.8%, to distant nodes in 24.2%, and to extranodal tissues in 12.4%. Lymphography showed abnormal retroperitoneal lymph nodes in 38.3% of cases. There was gastrointestinal involvement either initially or later in 17.6% of cases. High-energy radiation therapy to both sides of the neck was the treatment of choice for local and regional disease. It achieved a five-year survival rate of 41.9% in the group of 97 patients treated during the past decade. The incidence of relapse (recurrence and new manifestations) was highest in the first year after treatment.
