Clinical classification and survival in chronic lymphocyte leukemia.

Sixty-one consecutive patients with chronic lymphocytic leukemia (CLL) treated at the Istituto Nazionale Tumori of Milan from September 1962 to August 1976 were classified according to the staging system of Rai et al. (16). Analysis of this series showed the following median survival (in months) from diagnosis: stage 0-I, 73; stage II, 44; stage III-IV, 32. In 11 patients without peripheral palpable adenopathies, the lymphangiogram showed abnormal retroperitoneal lymph nodes. Therefore, the initial stage was changed from 0 to I in 5 cases. The median survival for the entire series was 50 months. Patients with "indolent" disease had a median survival of 52 months, while in patients with "active" CLL, the median survival was 32 months. Both sex and age were shown to be poor predictors of survival. Increased duration of survival was observed in patients with less compared to those with more than 30,000 lymphocytes/mm3 (66 versus 41 months). The method of staging proposed by Rai et al. and utilized to classify this series at the time of diagnosis was confirmed to be a reliable predictor for survival.

Combined surgery and chemotherapy for retroperitoneal metastases of testicular carcinomas other than pure seminoma.

The results of treatment in 210 patients with testicular carcinomas other than pure seminoma are analysed. Patients with negative retroperitoneal nodes had a very good prognosis following lymph node dissection alone. Patients with positive nodes did much better after adjunctive chemotherapy than after post-operative irradiation. Patients with advanced disease showed significant improvement with intensive chemotherapy combined with surgery. Presently retroperitoneal lymphadenectomy combined with intensive chemotherapy seems to be the treatment of choice for metastatic testicular carcinomas.

Controlled study with BCNU vs. CCNU as adjuvant chemotherapy following surgery plus radiotherapy for glioblastoma multiforme.

From September, 1972 to December, 1976, 102 consecutive patients operated on for glioblastoma multiforme were randomized, after total or subtotal tumor resection, to receive irradiation alone, irradiation plus BCNU or irradiation plus CCNU. BCNU and CCNU adjuvant chemotherapy was repeated every 6--8 weeks as long as the patients remained in complete remission. Patients were comparable for median age, type of surgery, and histological grade III and IV. Radiotherapy was administered at the tumor dose of about 5000 rads in all three groups. The percent of optimal dose administered was 96% for BCNU and 93% for CCNU. In the group treated with radiotherapy alone (32 cases) the median survival was 10.5 months, while in the groups treated with BCNU (34 cases) and CCNU (36 cases) the median survival was 12 and 16 months, respectively. Both relapse-free (P = 0.05) and total survival (P = 0.03) were significantly improved only in patients who were treated with radiotherapy plus CCNU compared to patients receiving radiotherapy alone after surgery. Present results show that in resectable glioblastoma multiforme, a slightly improved survival rate can be achieved by the prolonged use of adjuvant CCNU following maximal surgical resection and radiotherapy. The cure rate was not improved.

Cyclophosphamide, vincristine, and prednisone (CVP) versus adriamycin, bleomycin, and prednisone (ABP) in stage IV non-Hodgkin's lymphomas.

In stage IV non-Hodgkin's lymphomas, CVP (cyclophosphamide, vincristine, and prednisone) was randomly compared to ABP (adriamycin, bleomycin, and prednisone). Of 62 patients entered into the study, 57 (CVP 27, ABP 30) were considered evaluable for comparison. In patients with liver and/or marrow involvement a second biopsy was performed to define complete remission (CR). CR occurred in 48% of patients treated with CVP and in 50% of those given ABP. The median duration of CR was 10.5 and 20.5 months, respectively. The difference is not statistically significant. Also, the survival of complete responders was not significantly different between the two treatment groups. After cross-over, secondary treatment with CVP produced an overall response rate of 40% (six of 15), compared to 50% (six of 12) obtained with ABP. In the ABP group, four patients developed a reversible interstitial penumonia. In two other patients, cardiomyopathy (fatal in one) was observed. In conclusion, although complete remission was similar in both groups, cumulative toxicity occurred in few patients given ABP. However, this combination could represent an effective alternative treatment to be used either in CVP failures or sequence with CVP.

Non-cross-resistant combinations in stage IV non-Hodgkin's lymphomas.

Two triple-drug combinations (cyclophosphamide, vincristine, and prednisone [CVP] and adriamycin, bleomycin, and prednisone [ABP]) were randomly tested in 57 consecutive patients with pathologic stage IV non-Hodgkin's lymphoma. No statistical difference was observed in the incidence of complete remission (CR) (48% vs 50%), median duration of CR (10.5 vs 20.5 months), and survival. CR correlated positively with survival. After crossover for progression or relapse, no cross resistance was detected between the two combinations (CR plus PR = 40% for CVP and 50% for ABP). In a subsequent prospective study CVP and ABP were sequentially alternated in an attempt to improve the incidence and duration of CR. In the first 32 evaluable patients CR was produced in 50%. The findings are still preliminary.

Combination chemotherapy of Hodgkin's disease with adriamycin, bleomycin, vinblastine, and imidazole carboxamide versus MOPP.

This paper reports the preliminary results of a controlled study randomizing MOPP vs. a new four-drug combination (ABVD) in advanced Hodgkin's disease. ABVD consists of 6 cycles of adriamycin, bleomycin, vinblastine, and imidazole carboxamide. The purpose for designing this new combination was two-fold: to compare the efficacy of ABVD with MOPP, and to demonstrate absence of cross-resistance between the two regimens. Of 60 patients entered into the study, 45 (MOPP25, ABVD20) are presently evaluable for the analysis of remission induction. No patient was previously treated with chemotherapy; 20% had relapsed after primary radiotherapy. Whenever possible, complete remission was defined also through rebiopsy of known organ involvement. Complete remission occurred in 76% of patients treated with MOPP and in 75% of those given ABVD, with no difference between the two regimens as far as stage (IIIB-IIIS and IV), histologic type, and prior irradiation were concerned. Crossover carried out for progressive disease or for relapse after initial remission showed absence of cross-resistance between MOPP and ABVD. Toxic manifestations after ABVD were in general well tolerated and reversible. The percent of optimal dose for each drug was as follows: adriamycin 87%, vinblastine 87%, bleomycin 96%, and imidazole carboxamide 96%. These preliminary results indicate that in terms of complete remission, ABVD could represent a successful alternative to MOPP to be used either in MOPP failures or in sequential combination with MOPP. However, the lack of long-term followup limits at the present time an adequate comparison between the two treatments.

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.
