A total of 49 patients with metastatic renal cell cancer underwent recombinant interferon-alpha 2a therapy combined with chemotherapy. Before therapy the patients without nephrectomy underwent angioinfarction of the primary renal tumor. Combined treatment included interferon at 5 x 10(6) units per m.2 intramuscularly daily, 5-fluorouracil at 750 mg./m.2 daily by continuous infusion intravenously (days 1 to 5) and mitomycin C at 5 mg./m.2 per day intravenously (days 1 and 2) repeated every 28 days. Of the patients 17 (35%, 95% confidence interval 22 to 49%) responded, and all 17 had partial remission that lasted a median of 7.1 months (range 4.2 to 20.9+ months). Response rate differed by metastatic sites: lung 46% (18 of 39 patients), lymph nodes 46% (6 of 13), mediastinum 20% (2 of 10) and liver 18% (2 of 11). Grade 3 to 4 toxicity (World Health Organization) included neutropenia (79% of the patients), thrombocytopenia (45%), stomatitis (34%), diarrhea (8%), nausea (18%) and central nervous system disorders (18%). The overall 35% response rate suggests that the combination of interferon-alpha 2a, 5-fluorouracil and mitomycin C is synergistic. Future studies are needed to confirm this finding and to assess the role of mitomycin C.

A pharmacokinetic study of N-L-leucyl-doxorubicin, a new derivative of doxorubicin, has been undertaken during a phase I trial in 19 patients with advanced cancer after intravenous bolus administration at doses ranging from 30 to 240 mg/m2. The pharmacokinetics of N-L-leucyl-doxorubicin was linear with a total body clearance of 41.3 +/- 25.7 L/hr/m2. N-L-leucyl-doxorubicin was extensively metabolized into doxorubicin, which appeared in plasma immediately after N-L-leucyl-doxorubicin infusion. The mean molar doxorubicin/N-L-leucyl-doxorubicin area under the curve (AUC) ratio was 0.49 +/- 0.22 and was independent of the administered dose. A relationship has been established between the doxorubicin AUC (r = 0.74; p less than 0.001) and the surviving factor in white blood cell counts. Other toxic side effects (thrombocytopenia or stomatitis) did not correlate with any pharmacokinetic parameter. These findings suggest that the degree of metabolization of N-L-leucyl-doxorubicin into doxorubicin may be responsible for the toxicity, that is, N-L-leucyl-doxorubicin may simply represent a pro-drug for doxorubicin.

Sixty-six patients with locally advanced (Stages III and IV) carcinoma of the head and neck were treated with three cycles of induction chemotherapy, consisting of cisplatin, fluorouracil (FU) infusion, bleomycin, mitomycin, and hydroxyurea, followed by radiotherapy and/or surgery. There were 48 men and 18 women with a median age of 55 years (range, 18 to 75 years) and Karnofsky performance status of 80 (range, 40 to 90). Primary site was nasopharynx (28 patients), followed by larynx (12) and others (26). Forty-one (62%) patients were presented with Stage IV disease. The response rate to induction chemotherapy was 27% complete response, 50% partial response, 20% stable disease, and 3% progressive disease. There was no significant difference in response rate between patients with cancer of nasopharynx or other sites (P greater than 0.1). Survival was 61% at 24 months. Patients with cancer of nasopharynx had a better survival than those with other primaries (P = 0.033). Toxicities from chemotherapy included alopecia (73%), nausea/vomiting (66%), leukopenia (54%), stomatitis (36%), anemia (32%), thrombocytopenia (16%), and diarrhea (9%). Grade IV toxicity was not observed. Induction chemotherapy with this new regimen resulted in a high response rate but may not be superior to cisplatin and FU alone. It can be safely combined with radiotherapy as a potentially curative therapy in squamous cell carcinoma of the head and neck. Chemotherapy followed by radiation therapy may yield survival similar to radical surgery in laryngeal and other head and neck cancers.

COP-BLAM III therapy was given to 18 patients with non-Hodgkin's lymphoma, and the therapeutic effects as well as adverse effects of the treatment were examined. Of the 18 patients 16 had a complete remission (CR) and 2 showed an partial remission (PR) with a total response rate of 100%. In terms of the stage of disease, CR was achieved in all patients in stage III and in 11 of 13 patients in stage IV. Patients with neutrophil counts less than 1,000/microliters were given rhG-CSF (1.5 micrograms/kg/day, sc), which significantly shortened the duration of neutropenia and decreased the number of days with episodes of fever when compared with those not given rhG-CSF, consequently facilitating the treatment without prolonging the dosing intervals. No serious infection was observed. Adverse effects included neutropenia of less than 1,000/microliters in 6 of the 18 patients (33.3%), thrombocytopenia less than 5 x 10(4)/microliters in 3 (16.7%), nausea and vomiting in 8 (44.4%), peripheral neuropathy in 4 (22.2%) and stomatitis in 4 (22.2%). There were no fatalities caused by the treatment. The above findings indicate that COP-BLAM III therapy is capable inducing high frequency of complete remissions in non-Hodgkin's lymphoma and that its combination with G-CSF can improve the results of the therapy and relieve adverse reactions.

Castleman's disease is a rare, benign, lymphoproliferative disorder of unknown cause. The hyaline-vascular type is frequently associated with a localized mediastinal mass. The plasma-cell type is associated with constitutional symptoms, multicentric lymph node involvement, lymphoma development, and autoimmune disease-like laboratory abnormalities such as elevated erythrocyte sedimentation rate, anemia, and thrombocytopenia. We report a case of hyaline-vascular Castleman's disease associated with a cutaneous autoimmune disease, pemphigus vulgaris. We also reviewed the clinicopathologic features of four similar cases. Among these five reports of Castleman's disease, five patients had severe erosive stomatitis diagnosed as oral pemphigus, three had keratoconjunctivitis, and three had circulating pemphigus antibodies. All were young, ranging in age from 15 to 21 years, and four of the five were women. Two had hyaline-vascular Castleman's disease, whereas three had plasma-cell Castleman's disease. All five had surgical resection of the Castleman's disease mass. After surgery, remission of pemphigus vulgaris could be achieved with reduced dosages of steroids in all cases. In at least two cases steroid treatment could be completely discontinued. We postulate that an underlying immune dysfunction in Castleman's disease facilitates the expression of pemphigus.

Forty-nine patients with locally advanced squamous cell carcinoma of the head and neck (SCCHN) were treated with 3 cycles of induction chemotherapy prior to definitive local treatment (surgery and/or radiation therapy). Chemotherapy consisted of carboplatin 300 mg/m2 on day 1, fluorouracil 1000 mg/m2 daily as a continuous infusion on days 1 to 5 and high-dose methotrexate 1.2 g/m2 with leucovorin rescue on day 14. After completing the induction chemotherapy, 9 patients (18%) achieved a complete remission (CR), 26 (54%) a partial remission (PR), 7 had stable disease and 7 a progression. The response rates increased to 53% CR and 18% PR following locoregional treatment. Survival at 12 months was 61% and its actuarial probability at 24 months 31%. Median time to progression was 14 months. Toxicity from chemotherapy was generally mild. Nausea was observed in 35%, vomiting in 26%, stomatitis in 57%, anemia in 22%, leukopenia in 36%, thrombocytopenia in 26% and diarrhea in 6% of the patients. In conclusion, the combination of carboplatin, 5-day continuous-infusion fluorouracil and mid-cycle high-dose methotrexate is a moderately effective, well tolerated regimen in patients with SCCHN but does not seem superior to the combination of carboplatin and fluorouracil only.

Fifty-six patients with measurable or evaluable advanced gastric cancer were treated with cisplatin, 100 mg/m2 in continuous infusion of 24 hours, and 5-fluorouracil, 1000 mg/m2/day (by continuous 5-day infusion) every 4 weeks. Three patients were found ineligible for the study. A response rate of 41% (22/53) was obtained (95% confidence interval: 28%-54%), with a median duration of remission of 10.2 months and an overall median survival time of 10.6 months. Leukopenia and thrombocytopenia were mild. Nausea and vomiting were common, and 23.5% of the patients had grade 3 stomatitis. Peripheral neuropathy and renal insufficiency increased with the number of cycles, representing the cumulative dose-limiting toxicity. This study indicates that the combination of cisplatin plus 5-fluorouracil is synergistic or at least has additive antitumor activity. We think that this association of 2 drugs should be considered for further phase III clinical trials.

36 patients with advanced malignancy were studied in a phase I trial of continuous 24-h infusion of floxuridine (FUdR) plus etoposide plus cisplatin (FEP) administered for 5 consecutive days at 4-week intervals. Study design fixed the dose rate of etoposide and cisplatin with escalation of FUdR only. Dose rate-limiting toxicity related to the FUdR component was stomatitis and diarrhoea and was invariably associated with leukopenia and thrombocytopenia when grade 3 or 4 level gastrointestinal toxicity was observed. Only 3 of 64 courses were associated with transient renal failure related to cisplatin. Drug-related deaths occurred (leukopenia-associated sepsis) in 4 patients with poor performance status (ECOG 3 and 4). Responses occurred in 15 of 26 evaluable patients (all previously treated minimally or untreated) including 5/11 non-small cell lung cancer; 3/3 oesophageal; 2/2 breast; 4/5 gastric; 1 osteogenic sarcoma; and 1 unknown primary (probably ovary). The recommended dose rates for a 5-day infusion of the three agents for good risk patients is 20 mg/m2 per day of each drug. For poor risk patients including age greater than 65 years; performance status 2 or greater; or extensive bone metastases or prior radiation; the recommended starting dose rates are: FUdR 15 mg/m2 per day; etoposide 15 mg/m2 per day; and cisplatin 20 mg/m2 per day. Dose escalation of FUdR to a maximum of 25 mg/m2 daily is feasible in selected patients demonstrating optimal tolerance.

Fifty-two women with advanced breast cancer were treated with 6 cycles of epirubicin. Even though the study was started with a dose schedule of 110 mg/m2 every 3 weeks, the average treatment interval was 26 days and the median weekly dose 78% of the protocol requirement. Forty-eight patients were evaluable for response; 3 achieved a complete remission which lasted for 17, 24 and 65 weeks, respectively, and 14 a partial remission. Median survival was 32 weeks. Toxicity included nausea/vomiting (68%), anemia (24%), leukopenia (37%), thrombocytopenia (8%), alopecia (81%), stomatitis (24%), diarrhea (14%), fever (19%) and fatigue (14%). Also 1 treatment-related death occurred and 2 cases of arrhythmia. Monotherapy with high doses of epirubicin has definite activity in advanced breast cancer and deserves further study in combination with hematopoietic growth factors which might allow a higher dose intensity.

We performed a phase I trial of CI-937 (DUP937), an anthrapyrazole, with the following objectives: (a) to determine the maximally tolerated dose in humans; (b) to define the toxicity spectrum of this agent; (c) to describe the pharmacokinetics of the drug; (d) to test a pharmacokinetics based hypothesis of dose escalation; and (e) to relate drug pharmacokinetics to pharmacodynamics. CI-937 was administered as a single bolus injection every 3-4 weeks at doses ranging from 3.6 to 25.2 mg/m2. Thirty-two patients and 57 courses were evaluable for toxicity. Pharmacokinetic analysis was performed in 30 patients on the first course using a sensitive and selective radioimmunoassay. The maximally tolerated dose in patients with no prior therapy was 25.2 mg/m2 and dose-limiting toxicity was neutropenia. Thrombocytopenia, nausea, vomiting, stomatitis, and alopecia were mild. A partial response was recorded in a patient with mesothelioma. The area under the curve increased linearly with dose, and total body clearance of CI-937 was independent of dose. The mean total body clearance was 107 +/- 55.8 ml/min/m2, mean steady state volume of distribution was 492 +/- 469 liters/m2, and terminal half-life was 3.78 +/- 2.86 days. The extended factors of 2 methods of pharmacologically guided dose escalation were intended for use but ultimately were equivalent to that of the modified Fibonacci dose escalation method. Dose and the area under the curve were significant predictors of a percentage change in WBC and neutrophil count in a univariate analysis. Only dose and baseline neutrophil count predicted a percentage change in WBCs in a multifactor analysis. Dose and prior chemotherapy predicted percentage change in neutrophil count in a multifactor analysis. We conclude that the dose-limiting toxicity of CI-937 is neutropenia and that the recommended phase II starting dose is 22 mg/m2.
