A 51-year-old patient exhibited severe neutropenia over a period of 12 months following lobectomy for carcinoma of the lung. Marrow neutrophil mass and marrow neutrophil production were measured quantitatively and were within normal limits. Mobilization into a skin window was absent. A defect in neutrophil motility could be demonstrated in vitro and was confirmed in vivo by poor neutrophil release from the marrow following injection of hydrocortisone; it thus represented a lazy leukocyte syndrome of the adult.

The synergistic combination of cisplatinum and etoposide appears as the best second line treatment in patients relapsing from small cell lung carcinoma (SCLC). In order to test the dose-effect relationship of cisplatinum and etoposide in this situation, we have performed a randomised phase II trial comparing 2 five-day regimens: cisplatinum 20 mg/m2/day+etoposide 60 mg/m2/day (arm A) versus cisplatinum 40 mg/m2/day+etoposide 100 mg/m2/day (arm B) every 4 weeks. Thirty-seven patients were included (arm A: 18, arm B: 19), and 32 were considered to be eligible (arm A: 15, arm B: 17). Eight patients were non evaluable, five of them because of toxic death occurring prior to the second course (arm A: one from neutropenia; arm B: three from neutropenia and one from thrombopenia). The two groups were well balanced with regard to the main prognostic factors (age, sex, performance status, LDH level, response to induction chemotherapy). An objective response was observed in 10/24 evaluable patients (arm A: 4, arm B: 6) and was considered as complete in one patient in arm A and in 2 pts in arm B; these two patients presented with cerebral metastases and their response lasted 9 and 15 weeks respectively. The mean duration of response was 11 weeks in arm A and 10.5 weeks in arm B. The median actuarial survival of the overall population of eligible patients was 15 weeks: 13 weeks in arm A and 16.5 weeks in arm B. The study was discontinued because of the 23.5% toxic deaths rate in the high doses arm in this heavily pre-treated population of patients. However, the high response rate (54% overall, 35% considering toxic death as a failure) is impressive and presents evidence for the dose/effect relationship in SCLC.

Forty-one patients with unresectable non-small cell carcinoma of the lung (NSCCL) were treated with cisplatin 20 mg/m2/d for 5 days as a daily bolus injection, 5-fluorouracil 800 mg/m2/d by continuous infusion for 5 days, and intermediate-dose methotrexate 200 mg/m2 on days 15 and 22 of a 28-day cycle (PFM). One complete and 23 partial responses were observed, yielding an overall response rate of 60%. There was no significant difference in response rates based on histologic subtype or extent of disease (locally unresectable versus metastatic). Median duration of response was 6 months, and the median survival of all patients was 10 months. Two patients with unresectable disease at presentation became resectable after chemotherapy and remain disease-free at 46+ and 53+ months. Toxicity was modest, with oral mucositis the major adverse effect. Clinically important neutropenia was uncommon. PFM is an active regimen in NSCCL and deserves further study in the "neoadjuvant" setting.

Eighteen patients with advanced solid tumors were treated in a phase I study of cisplatinum in combination with recombinant alpha-2a interferon (Roferon-A, Hoffman-LaRoche, Inc, Nutley, NJ). Roferon-A was administered at a dose of 5 MU/m2 S.C. three times a week and the dose levels of cisplatinum were 15, 20, 25, 33, and 42 mg/m2/week given intravenously. All patients experienced grade I/II fatigue, nausea and vomiting. Grade III toxicity occurred in 4/6 patients at dose level 4. The dose limiting toxicities were myelosuppression [leukopenia (two patients), neutropenia (one patient), thrombocytopenia (one patient)], vomiting (one patient) and severe fatigue leading to a decrease in performance status (one patient). One patient with non-small cell lung carcinoma had a mixed response and another a minor response. The recommended dose level of this combination for phase II studies is cisplatinum 25 mg/m2/week and Roferon-A 5 MU/m2 three times a week.

Thirty-two previously untreated, fit patients with small-cell lung carcinoma (SCLC) were treated with an intensive combination chemotherapy regimen, with the aim of prolonging survival, as follows: carboplatin 400 mg/m2 intravenously (IV) day 1, ifosfamide 5 g/m2 IV day 1 in a 24-hour infusion with mesna, and etoposide 100 mg/m2 IV days 1 to 3, repeating at 28-day intervals for six courses. Limited-disease (LD) patients were given concurrent hyperfractionated radiotherapy for the first two courses, and all patients achieving a complete remission (CR) were offered prophylactic cranial irradiation (PCI). For 18 LD patients, the overall response was 94% with 72% CRs. For 14 extensive-disease (ED) patients the overall response was 100% with 29% CRs. Median response duration for LD patients was 11.5 months and for ED patients 7.5 months. Median survival for LD patients was 19 months with a predicted 24% 2-year survival and for ED patients 9.5 months with a predicted 14% 2-year survival. Hematologic toxicity was severe with 100% developing World Health Organization (WHO) grade 3-4 neutropenia and 94% WHO grade 3-4 thrombocytopenia during treatment. Seventy-two percent of patients required a dose reduction at some stage during treatment because of neutropenic infection or thrombocytopenia requiring platelet transfusions. Despite very high response rates, this intensive regimen achieves survival results only modestly better, if at all, than those reported for less toxic conventional regimens.

A total of 31 patients with previously untreated small-cell carcinoma of the lung were treated with very-high-dose cyclophosphamide, using autologous bone marrow transplantation (ABMT) to assist haematological recovery. The period of neutropenia was shorter with 40 mg/kg cyclophosphamide x 4 (7 patients) than when the dose of cyclophosphamide was increased to 50 mg/kg x 4 (11 patients), despite ABMT 2 days after chemotherapy in each group. In all, 13 patients were treated with 50 mg/kg cyclophosphamide x 4, with infusion of bone marrow delayed to day 4, 6 or 8 after chemotherapy to determine the contribution of ABMT to haematological recovery. The period of neutropaenia was increased when marrow was returned 6 days following chemotherapy, confirming that ABMT contributed to haematological recovery after this schedule of treatment. A total of 11 patients had a second cycle of 50 mg/kg cyclophosphamide x 4 after recovery from the first cycle of high-dose chemotherapy. The period of myelosuppression was greater with the second cycle of chemotherapy, although ABMT was carried out during both cycles. The results show that ABMT contributes to haematological recovery when the dose of cyclophosphamide is high enough to produce prolonged hypoplasia. The increased myelosuppression observed after a second high-dose treatment in spite of ABMT suggests either that both transplanted and endogenous marrow activity contribute to recovery of myelopoiesis or that there is residual damage to marrow stroma after the first cycle of treatment. The data indicate the necessity of carefully assessing the role of ABMT in haematological recovery with high-dose chemotherapy regimens.

Eighty-seven patients with histologically or cytologically proven non-small-cell carcinoma of the lung were treated with 4'-deoxydoxorubicin (DxDx) 30 mg/m2 every 3 weeks. Three responses (4%), all partial, were observed. All responses occurred in patients with large-cell anaplastic lung cancer and none in squamous or adenocarcinoma histologies (P less than 0.01). The durations of partial response for these three responders were 70, 198+ and 209+ days. The side effects noted were predominantly neutropenia, anemia, and weight loss. In three patients, declines in cardiac ejection fraction of 7%, 12%, and 23% occurred after cumulative drug doses of 150 mg/m2, 150 mg/m2, and 233 mg/m2, respectively. 4'-Deoxydoxorubicin had little activity in non-small-cell lung cancer at the dose used in this study.

This pilot study in limited-stage small-cell carcinoma of the lung using concurrent cisplatin (Platinol) and etoposide (VePesid) chemotherapy with radiotherapy has yielded a high complete response rate in 23 of 40 patients evaluable for response. Five of these responders have survived greater than 2 years off all therapy with a stable, high performance status. Median survival of all patients is 18 months. Toxicity has been acceptable, the most common being neutropenia. Radiation toxicities include 17 of 40 patients experiencing mild to moderate esophagitis, with one severe toxicity; and three of 40 patients developing mild to moderate radiation pneumonitis. The high complete remission observed with this program and the long tumor-free interval seen off maintenance therapy deserve further exploration. Toxicities appear only moderately greater than with other programs currently utilized.

Three patients with idiopathic pancytopenia and hypercellular bone marrow who developed carcinoma of the lung within two years of diagnosis are reported. All three patients had macrocytic anemia associated with a megaloblastic marrow in the presence of normal serum vitamin B12 and folic acid levels. Neutropenia with monocytosis, elevated serum muramidase and LAP scores, and increased fetal hemoglobin levels were also found. In all cases Ham's tests were negative with a normal bone marrow karyotype. In all three patients, pancytopenia due to myelodysplasia, a probable preleukemic state, was diagnosed initially prior to the appearance of carcinoma of the lung. One of the patients showed improved leukocyte and platelet counts during chemotherapy, while the other two died before chemotherapy could be administered. In the light of the above findings we suggest that carcinoma of the lung may be the cause of a paraneoplastic syndrome with pancytopenia, particularly in patients with a hypercellular marrow with a normal karyotype.

A phase II study of mitoxantrone, an anthraquinone derivative with structural similarities to adriamycin, has been carried out in 34 patients with advanced breast carcinoma and other malignancies. The first 20 patients were treated with a starting dose of 12 mg/m2 by IV infusion repeated every 3 weeks; this was escalated to 14 mg/m2 in the subsequent 14 patients. Of the 29 patients with advanced breast carcinoma, 8 achieved a partial response and two further patients achieved a mixed response. There were no complete responses. Of the eight responding patients, five had received no prior chemotherapy. Response duration ranged from 3 1/2 months to 10+ months. No responses were seen in the other five patients, three whom had small cell carcinoma of the lung, and one colonic carcinoma. Neutropenia was the most frequently seen toxicity but was usually mild and transient; WBC fell to less than 2,000/mm3 in eight patients and to less than 1,000/mm3 in only two. Otherwise, the drug was well tolerated; nausea occurred in 35% of patients and vomiting in 21%; severe alopecia requiring a wig was never seen. Mitoxantrone appears to be a well-tolerated and clinically active agent against advanced breast carcinoma.
