Recombinant human erythropoietin in the treatment of chemotherapy-induced anemia and prevention of transfusion requirement associated with solid tumors: a randomized, controlled study.

BACKGROUND: Anemia is a common side effect of anticancer chemotherapy. Blood transfusion, previously the only available treatment for chemotherapy-induced anemia, may result in some clinical or subclinical adverse effects in the recipients. Recombinant human erythropoietin (rhEPO) provides a new treatment modality for chemotherapy-induced anemia. PATIENTS AND METHODS: To evaluate the effect of rhEPO on the need for blood transfusions and on hemoglobin (Hb) concentrations, 227 patients with solid tumors and chemotherapy-induced anemia were enrolled in a randomized, controlled, clinical trial. Of 189 patients evaluable for efficacy, 101 received 5000 IU rhEPO daily s.c., while 88 patients received no treatment during the 12-week controlled phase of the study. RESULTS: The results demonstrate a statistically significant reduction in the need for blood transfusions (28% vs. 42%, P = 0.028) and in the mean volume of packed red blood cells transfused (152 ml vs. 190 ml, P = 0.044) in patients treated with rhEPO compared to untreated controls. This effect was even more pronounced in patients receiving platinum-based chemotherapy (26% vs. 45%, P = 0.038). During the controlled treatment phase, the median Hb values increased in the rhEPO patients while remaining unchanged in the control group. The response was seen in all tumor types. CONCLUSIONS: RhEPO administration at a dose of 5000 IU daily s.c. increases hemoglobin levels and reduces transfusion requirements in chemotherapy-induced anemia, especially during platinum-based chemotherapy.

Topotecan, a new active drug in the second-line treatment of small-cell lung cancer: a phase II study in patients with refractory and sensitive disease. The European Organization for Research and Treatment of Cancer Early Clinical Studies Group and New Drug Development Office, and the Lung Cancer Cooperative Group.

PURPOSE: To assess activity and toxicity of topotecan in previously treated small-cell lung cancer (SCLC) patients. PATIENTS AND METHODS: Patients with measurable SCLC, progressive after one first-line regimen, were eligible for the study. Two groups of patients were selected: (1) patients who failed first-line treatment < or = 3 months from chemotherapy discontinuation (refractory group); and (2) patients who responded to first-line treatment and progressed greater than 3 months after chemotherapy discontinuation (sensitive group). Topotecan was administered as a 30-minute daily infusion at a dose of 1.5 mg/m2 for 5 consecutive days, every 3 weeks. RESULTS: One hundred one patients were entered onto the study and 403 courses were administered. Ninety-two patients (47 refractory and 45 sensitive) were eligible and assessable for response. Among refractory patients, there were two partial responses (PRs) and one complete response (CR), for an overall response rate of 6.4% (95% confidence interval [CI], 1.3% to 17.6%), whereas in the sensitive group, there were 11 PRs and six CRs, for an overall response rate of 37.8% (95% CI, 23.8% to 53.5%). Overall median duration of response was 7.6 months. Median survival was 5.4 months; median survival of refractory patients was 4.7 months, whereas that of sensitive patients was 6.9 months (P = .002). Median survival of responding patients was 12.5 months. Toxicity was mainly hematologic. Leukopenia, although short-lived, was universal, with grade III and IV neutropenia occurring in 28% and 46.8% of cycles, respectively. Nonhematological toxicity was mild. Fatigue/malaise was reported in 39.3% of cycles and transient elevation of liver enzymes in 17%. CONCLUSION: Topotecan has significant activity in SCLC, particularly in patients sensitive to prior chemotherapy, with predictable and manageable toxicity. The incorporation of topotecan in combination chemotherapy regimens for future treatment of SCLC is warranted.

EO9 phase II study in advanced breast, gastric, pancreatic and colorectal carcinoma by the EORTC Early Clinical Studies Group.

In a phase II trial, the activity of EO9, a new bioreductive alkylating agent, was assessed. EO9 was used as second-line chemotherapy in breast cancer patients and as first-line chemotherapy for patients with gastric, pancreatic and colorectal cancer. EO9 was given as a 5 min i.v. infusion at a weekly dose of 12 mg/m2. 92 patients were entered; 22 with breast cancer, 26 with colon cancer, 24 with pancreatic cancer and 20 with gastric cancer. In general, the drug was well tolerated with nausea and vomiting occurring in 26.42 and 13.3% of courses, respectively. Reversible proteinuria was the main toxicity occurring in 45% of courses. Antitumour activity was not observed. At this dose and schedule, EO9 is not an active drug in the type of tumour studied.

A randomized phase II study with two schedules of the novel indoloquinone EO9 in non-small-cell lung cancer: a study of the EORTC Early Clinical Studies Group (ECSG).

In a multicentre randomized trial of the EORTC-ECSG, we have treated 38 chemotherapy naïve patients with advanced non-small-cell lung cancer (NSCLC) with EO9, a novel bio-reductive alkylating indoloquinone. The drug was given at two different dose schedules by a single bolus i.v. injection: arm A 12 mg/m2 weekly and arm B 22 mg/m2 every three weeks. All together 185 courses were administered (145 in arm A and 40 in arm B). The major toxicity was reversible proteinuria more frequently occurring in the three-weekly schedule (arm A 34.5% vs. arm B 62.5%). Creatinine elevation, fluid retention and pericardial or pleural effusion were also recorded in a limited number of patients. Other common toxicities more frequent in the three-weekly administration were asthenia (21% vs. 35% of cycles), nausea (15% vs. 27.5% of cycles) and vomiting (5% vs. 17.5% of cycles). Toxicities were mainly of grade I and II. No responses have been observed. Five patients (26%) on arm A and eight (53%) on arm B experienced stable disease. These doses and schedules of EO9 do not yield activity in NSCLC.

An ongoing European organization for research and treatment of cancer crossover trial comparing single-agent paclitaxel and doxorubicin as first- and second-line treatment of advanced breast cancer.

The activity of paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) in advanced breast cancer patients who have failed doxorubicin treatment is well established, but the optimal sequence between these two important agents remains to be determined. The European Organization for Research and Treatment of Cancer therefore designed a prospective randomized clinical trial in which patients not exposed to anthracyclines in the adjuvant setting received either first-line paclitaxel, given as a 3-hour infusion at a dose of 200 mg/m2 followed at the time of disease progression by second-line doxorubicin, given as a bolus injection at a dose of 75 mg/m2 or the reverse sequence. The target accrual is 330 patients. Interim results on 207 evaluable patients of 289 randomized are presented.

Adenocarcinoma

Biological response modifiers.

Biological response modifiers (BRMs) of current clinical interest may be divided into two categories: immunomodulating agents and colony stimulating factors (CSFs). The first are employed to potentiate the host defences towards the tumor but results have proved disappointing in non-small cell lung cancer (NSCLC). With regard to the second, the real dose increment which may be ascribed to CSFs is not sufficient to overcome chemoresistance of NSCLCs. CSFs can, however, reduce the hematologic toxicity of chemotherapy, which represents the most significant result.

Topotecan in colorectal cancer: a phase II study of the EORTC early clinical trials group.

PURPOSE: This phase II study with the topoisomerase I inhibitor topotecan was performed to determine its clinical activity and toxicity in patients with metastatic or locally unresectable colorectal cancer. PATIENTS AND METHODS: Topotecan 1.5 mg/m2 was administered intravenously by 30-minute infusion for 5 days. Fifty-nine patients entered the study, 2 were considered ineligible and 57 were evaluable for response and toxicity. RESULTS: Partial response was obtained in 4 of 57 evaluable patients (7%). The median duration of the response was 11 months (range 9.3 to 12.2). This topotecan regimen was very well tolerated. A total of 290 courses were given, with a median of 4 courses per patient (range, 1 to 18). The major toxic effects were leuko- and neutropenia (91%), grade 3-4 in 48% and 79% of courses, respectively, but with only 2 infectious complications. Other side effects were grade 1 alopecia (77%) in 46%, nausea (35%), vomiting (10%), and maculo-papular rash (6%). CONCLUSIONS: Topotecan administered as a daily-times-five regimen has only minor activity as a single-agent therapy in colorectal cancer.
