Abstract

We analyzed 47 immunologically confirmed cases of diffuse large B-cell lymphoma (DLBL) to determine whether the histologic type, surface immunoglobulin (Ig) phenotype, or mitotic rate predicted the clinical outcome. All patients were uniformly staged and uniformly treated with one six-drug protocol. Seventeen cases were subclassified as the noncleaved cell type (DLBL-NC), 23 cases as the immunoblastic type (DLBL-IBL), and 7 cases as other follicular center cell (FCC) types (DLBL-O). The predicted two-year actuarial survival for patients with DLBL-O (82%) was significantly longer than for those with DLBL-NC (35%; p = 0.05). The immunologic phenotype and mitotic rate also predicted the clinical outcome. The predicted two-year survival for patients with DLBL having a surface IgM phenotype (29%; p = 0.06), and the two-year survival for patients with FCC-derived DLBL (DLBL-NC plus DLBL-O) having a surface IgG phenotype (80%) was significantly longer than for those with a surface IgM phenotype (0%; p = 0.02). Similarly, the two-year survival for patients with DLBL having less than 30 mitoses (68%) was significantly longer than for those having greater than or equal to 30 mitoses per 10 high-power fields (28%; p = 0.01). These findings are considered preliminary, and additional studies of a large number of similar patients are necessary for their confirmation.

Potential impact on tumor control and organ preservation with cisplatin and 5-fluorouracil for patients with advanced tumors of the paranasal sinuses and nasal fossa. A prospective pilot study.

METHODS: Twelve patients with advanced epithelial nonadenocarcinoma of the paranasal sinuses and nasal fossa were treated with three cycles of cisplatin (100 mg/m2, day 1) and 5-fluorouracil (1000 mg/m2/24 hours on days 1-5 by continuous infusion), followed by preoperative external radiation therapy of 48 Gy and limited surgery, clearing the paranasal sinuses and nasal fossa. RESULTS: After chemotherapy, 11 of 12 patients were free of the previous symptoms of disease. Clinical response rates were different, however, with an overall response rate of approximately 70% with no complete responses. Histopathologic analysis of resected specimens showed no vital tumor in eight patients, minimal microscopic disease in three patients, and infiltrating tumor in one patient. Local control was achieved in 11 of 12 patients. Ten patients are alive with no evidence of disease (mean follow-up, 27 months). Surgical mutilation was avoided, with no functional or cosmetic loss. CONCLUSIONS: The results of this small pilot study seem to indicate a high chemosensitivity of carcinomas of the paranasal sinuses and nasal fossa, which, in this study, has meant significant relief of symptoms and an unusually high rate of local control (90%) without mutilation.

Urokinase combination chemotherapy in small cell lung cancer. A phase II study.

BACKGROUND AND METHODS: Fifty-one patients with small cell lung cancer (SCLC) were treated with alternating urokinase (UK)-cyclophosphamide-doxorubicin (Adriamycin, Adria Laboratories, Columbus, OH)-vincristine and cisplatin-etoposide-vincristine. UK was given as a loading dose of 3000 micrograms/kg body weight, followed by 3000 micrograms/kg/h for 6 hours. Thoracic irradiation with split technique (46 Gy) and prophylactic cranial irradiation (25 Gy) were administered to responding patients. A second staging was performed in patients exhibiting a clinical complete response (CR) after 1 year. RESULTS: In 27 patients with limited disease, there were 23 CR and 8 partial responses (PR) (CR, 85.1%; 66.2-95.8% at 95% confidence intervals); in 24 patients with extensive disease, there were 17 CR, 4 PR, and 3 cases with progression. Pathologically proven CR were observed in 59.2% patients with limited disease and 33.3% patients with extensive disease. Survival rates were as follows: in patients with limited disease, 1 year, 85.1%; 2 years, 55.5%; and 3 years, 25.9%; in patients with extensive disease, 1 year, 54.1; and 2 years, 16.9%. Median survival times were 26.3 months (patients with limited disease) and 13.3 months (patients with extensive disease). UK-related toxic effects included four episodes of mild to moderate bleeding, one allergic reaction, and one cerebrovascular accident. Myelotoxicity was severe, with a median of two episodes of Grade III-IV (World Health Organization classification) aplasia per patient. CONCLUSIONS: These results are consistent with a potential benefit of fibrinolytic therapy in combination with chemotherapy in patients with SCLC with limited disease. Additional trials are indicated.
