Given their known activity against non-small cell lung cancer, paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) and carboplatin were combined in this phase I study of patients with metastatic disease to determine the maximum tolerated dose and the dose-limiting toxicity of the combination. The initial dose of paclitaxel was fixed at 135 mg/m2 given as a 24-hour infusion with carboplatin administered in escalating doses in cohorts using Calvert's formula-dose (mg) = target AUC x (GFR + 25), where AUC is area under the concentration-time curve and GFR is glomerular filtration rate-based on target AUCs of 5, 7, 9, or 11 mg/mL.min. Dose escalations were based on cycle 1 toxicities. Filgrastim was not administered with the first cycle until two or more patients developed grade 4 or febrile neutropenia at the preceding dose level. Dose-limiting toxicity occurred in two patients at level 2 (cycle 1), and filgrastim was administered thereafter for the next four dose levels. Grade 4 thrombocytopenia was seen at level 4; thus, the carboplatin dose was de-escalated thereafter, and the paclitaxel dose escalated. Rare nonhematologic toxicities include fatigue, diarrhea, and nausea and vomiting. Among the first 30 patients, one had a complete response and 14 had partial responses, for an overall response rate of 50%. The combination of paclitaxel and carboplatin is active in non-small cell lung cancer, and the recommended phase II dose without filgrastim support is paclitaxel 175 mg/m2 via a 24-hour infusion with the carboplatin dose targeted to achieve an AUC of 7 mg/ mL.min.

Allogeneic peripheral blood stem cell transplantation leads to an earlier engraftment compared to BMT. The feasibility, acceptance and long-term side-effects of G-CSF mobilisation of PBSC in unrelated healthy donors needs to be evaluated. Forty unrelated healthy donors received G-CSF in a dose of 10 microg/kg bodyweight for 5 days and two aphereses were performed. The donors were monitored prospectively. The data were compared to bone marrow harvests from unrelated donors. Almost all stem cell donors reported some side-effects due to Filgrastim application. Bone pain (32), headache (20), chest pain (two) and night sweats (one) were complained of. By taking analgesics, the pain was relieved in most cases. No donor discontinued the filgrastim application. Bone pain and headache resolved within 2-4 days after termination of Filgrastim application. There was, as expected, a seven-fold increase in the number of total WBCs. There were no significant changes of platelet counts during G-CSF application. After 4 weeks haemoglobin concentration and platelet counts showed no significant differences compared to baseline values. The aphereses were mostly tolerated very well. Eighteen donors reported paraesthesia, one donor developed dizziness, two complained of nausea and vomiting. There was a significant decrease in platelet count (242 before, 98 x 10(9)/l after aphereses). Autologous platelets were transfused after the second aphereses in four donors. These data were compared to data from 245 unrelated bone marrow donors, who had on average, 14 days bone pain and tiredness after donation. The G-CSF mobilisation and apheresis of peripheral blood stem cells is an alternative to traditional bone marrow harvesting in unrelated healthy donors. It is well tolerated and the duration of side-effects on average is shorter than after the surgical procedure. So far no long-term effects have been observed in the follow-up.

An important issue in allogeneic peripheral blood progenitor cell transplantation is the optimization of the regimen of mobilization of progenitor cells from normal donors. It has been shown that for G-CSF doses up to 10 microg/kg/day, a dose-response relationship exists for the degree of progenitor cell mobilization. Formal comparisons with doses higher than 10 microg/kg/day, however, have not been reported. The aim of this study was to compare the mobilization and collection results of two different G-CSF (Filgrastim) schedules: 10 microg/kg/12 h (n = 20; group A) vs 10 microg/kg/24 h (n = 20; group B). Apheresis sessions were started on day 5 (after 4 days of G-CSF). Adverse events consisted of bone pain, headache, and fatigue which required treatment with acetaminophen +/- codeine in both donor groups. Discontinuation of G-CSF administration for intolerable side-effects was not necessary in any case. The increase in peripheral leukocyte and lymphocyte counts x 109/l on day 5 was higher in group A (56.2 (37.1-75.2) and 4.4 (2. 1-14.6), respectively) than in group B (27.5 (13.2-53.9) and 2.6 (1. 9-5.1), respectively) (P < 0.0001 and P = 0.008). Platelets x 109/l decreased in group A from 228 (161-286) before G-CSF administration to 207 (155-328) on day 5 (P = 0.03), whereas no change was observed in group B. Following the first apheresis, a significant decrease in platelet count was observed with both G-CSF schedules without any differences between groups. The number x 106/kg of both nucleated and CD34+ cells collected after the first apheresis session was higher in group A (672 (462-992) and 5.9 (3.4-10.4), respectively) than in group B (427 (319-608) and 3.1 (1.1-6.8), respectively) (P = 0.0003 in both cases). The median number of CD3+cells x 106/kg collected after one apheresis session was similar with both G-CSF schedules (212 (91-430) in group A and 170 (110-291) in group B) (P = NS). In conclusion, the schedule of 10 microg/kg/12 h was well tolerated and resulted in the collection of a higher number of progenitor cells than 10 microg/kg/24 h without increasing the T cell content. This approach could avoid the donor having to undergo a second apheresis, and facilitate further graft manipulation.

Neo-adjuvant, dose-dense docetaxel, 100 mg/m(2) every 2 weeks x 4 cycles, was administered to 12 patients with locally advance breast cancer (LABC) (10 stage IIIa and three stage IIIb). Eligibility requirements included a PS 0-2, normal hepatic and renal function, and radiologic absence of metastatic disease. Filgrastim [granulocyte colony stimulating factor (G-CSF)] was started 1 day after chemotherapy and was given for 6 days. Complete blood counts were determined weekly. Surgery was planned upon recovery from the last dose of docetaxel and followed by 4 cycles of adjuvant doxorubicin plus cyclophosphamide (AC) and radiotherapy. Patients with ER status received tamoxifen. The median age was 45 (range 34-73) and pre-treatment pathology revealed poorly differentiated infiltrating duct carcinoma in 11 and infiltrating lobular cancer in one, with positive ER/PR status in five. Twelve patients were treated, and all are evaluable for response and toxicity. Nine patients had a major clinical tumor response with five PR and four pathologic complete responses (pCR rate of 33%). Three patients (of whom two with stage IIIb) had progressive disease and went on to receive neo-adjuvant therapy with AC. There was one instance of grade 3 hematologic toxicity (neutropenic fever in one G-CSF non-compliant patient). There were two instances of grade 3 extra-hematologic toxicity: one patient had severe pain and one had treatment-related fatigue. After a median follow-up of 20 months (range 7-49 months) all patients are alive and eight of nine responders remain progression-free. Despite the small size of our study, we believe that dose-dense neo-adjuvant docetaxel is well tolerated and its activity warrants confirmation in a larger number of patients.

The incidence of gastric cancer (GC) increases significantly after the fifth decade and palliative chemotherapy is the ultimate treatment in the majority of patients. We investigated safety and efficacy of a weekly regimen with cisplatin, fluorouracil and leucovorin as first-line chemotherapy for elderly patients with advanced GC. Chemotherapy-naive patients older than 65 years were considered eligible for study entry. Frail elderly patients were identified and excluded according to the following criteria: age >85 years, dependence in one or more activities of daily living (activities of daily living and instrumental activities of daily living scales), three or more comorbid conditions, one or more geriatric syndromes. Chemotherapy consisted of 1-day per week administration of intravenous cisplatin 35 mg m(-2), 6S-stereoisomer leucovorin 250 mg m(-2) and fluorouracil 500 mg m(-2) (PLF). Patients were re-evaluated after eight weekly cycles and six additional weekly administrations were planned for patients without disease progression. A 5-day subcutaneous filgrastim (5 mug Kg(-1) day(-1), days +1-+5) was used after the first treatment delay for neutropenia and maintained thereafter. In the whole group, the best intention-to-treat overall response rate was 43% (95% CI: 30-56%). The time to disease progression and the median survival time were 5.3 and 8.6 months, respectively. Fatigue was the commonest nonhaematologic toxicity (71% of the patients). Filgrastim was used in 30 patients who showed grade II (20 patients) or grade III (10 patients) neutropenia. Neither grade IV toxicity nor toxic deaths were observed. The weekly PLF regimen resulted safe and effective in elderly patients with advanced GC. This outpatient regimen is based on old and low-cost drugs and it may represent an alternative to new and more expensive combinations.

Administration of filgrastim (recombinant human granulocyte colony-stimulating factor [rhG-CSF]) (Neupogen) in healthy donors to mobilize hematopoietic stem cells (HSCs) is a widespread practice in adults. Application of peripheral blood stem cell (PBSC) collection in normal pediatric donors is scarce due to ethical issues. Hence, there are insufficient data on the long-term impact of PBSC procedure in healthy children. This retrospective study aimed to evaluate the early and late adverse effects of PBSC donation in pediatric donors. Bone marrow and PBSC procedures and known adverse events of each technique were completely explained to parents and when applicable to children and written informed consent was obtained. rhG-CSF was administered for 4 days. HSCs were collected on the fifth day through continuous-flow apheresis and donors were followed for 30 days. Manual chart review was performed to collect short-term complications. Donors' health status was assessed via a questionnaire. A total of 145 healthy pediatric donors with a median age of 10 years at the time of donation (2 to 15 years) were followed for a median of 4.8 years (range, 1.2 to 14.2 years). The most frequent symptoms of rhG-CSF administration were fatigue (5%) and headache (3%). Thirty-five (24%) donors experienced hypocalcaemia during apheresis procedure that quickly responded to treatment. Two pregnancies occurred after rhG-CSF administration that resulted in normal births. We did not encounter any serious adverse events, including neoplastic disorders and death in this study. rhG-CSF and leukophresis procedure were well-tolerated in this study and all children completed the donation process without interruption or reduction of rhG-CSF dosage. Our results suggest that rhG-CSF is a safe drug in healthy children for the purpose of HSC mobilization.
