Collection of circulating progenitor cells after epirubicin, paclitaxel and filgrastim in patients with metastatic breast cancer.

The efficacy of high-dose chemotherapy (HDC) and circulating progenitor cell (CPC) transplantation in metastatic breast cancer (MBC) relies mainly on giving this treatment after a response to conventional induction chemotherapy has been achieved. For this reason an optimal mobilization regimen should be therapeutically effective while minimizing the number of leucaphereses required to support the myeloablative therapy. The combination of an anthracycline and paclitaxel in chemotherapy-untreated MBC has produced impressive response rates. We evaluated the CPC-mobilizing capacity of the combination epirubicin (90 mg m(-2)) and paclitaxel (135 mg m(-2)) followed by filgrastim (5 microg kg(-1) day(-1)) starting 48 h after chemotherapy administration in ten patients with MBC who were eligible for an HDC and CPC transplantation programme. Leucaphereses were performed by processing at least two blood volumes per procedure at recovery from neutrophil nadir when CD34+ cells in the peripheral blood exceeded 20 microl(-1). In most patients (six out of 10) more than 2.5 x 10(6) CD34+ cells kg(-1), a threshold considered to be sufficient for haematopoietic reconstitution, were collected with a single apheresis. In the remaining four patients an additional procedure, performed the following day, was enough to reach the required number of progenitors. These data suggest that the epirubicin-paclitaxel combination, besides being a very active regimen in MBC, is effective in releasing large amounts of progenitor cells into circulation.

Recombinant human granulocyte colony-stimulating factor (filgrastim) following high-dose chemotherapy and peripheral blood progenitor cell rescue in high-grade non-Hodgkin's lymphoma: clinical benefits at no extra cost.

In order to evaluate the potential clinical and economic benefits of granulocyte colony-stimulating factor (G-CSF, filgrastim) following peripheral blood progenitor cells (PBPC) rescue after high-dose chemotherapy (HDCT), 23 consecutive patients aged less than 60 years with poor-prognosis, high-grade non-Hodgkin's lymphoma (NHL) were entered into a prospective randomized trial between May 1993 and September 1995. Patients were randomized to receive either PBPC alone (n = 12) or PBPC+G-CSF (n = 11) after HDCT with busulphan and cyclophosphamide. G-CSF (300 microg day[-1]) was given from day +5 until recovery of granulocyte count to greater than 1.0 x 10(9) l(-1) for 2 consecutive days. The mean time to achieve a granulocyte count > 0.5 x 10(9) l(-1) was significantly shorter in the G-CSF arm (9.7 vs 13.2 days; P<0.0001) as was the median duration of hospital stay (12 vs 15 days; P = 0.001). In addition the recovery periods (range 9-12 vs 11-17 days to achieve a count of 1.0 x 10(9) l[-1]) and hospital stays (range 11-14 vs 13-22 days) were significantly less variable in patients receiving G-CSF in whom the values clustered around the median. There were no statistically significant differences between the study arms in terms of days of fever, documented episodes of bacteraemia, antimicrobial drug usage and platelet/red cell transfusion requirements. Taking into account the costs of total occupied-bed days, drugs, growth factor usage and haematological support, the mean expenditure per inpatient stay was pound sterling 6500 (range pound sterling 5465-pound sterling 8101) in the G-CSF group compared with pound sterling 8316 (range pound sterling 5953-pound sterling 15,801) in the group not receiving G-CSF, with an observed mean saving of 1816 per patient (or 22% of the total cost) in the G-CSF group. This study suggests that after HDCT and PBPC rescue, the use of G-CSF leads to more rapid haematological recovery periods and is associated with a more predictable and shorter hospital stay. Furthermore, and despite the additional costs for G-CSF, these clinical benefits are not translated into increased health care expenditure.

Intensive weekly chemotherapy for locally advanced gastric cancer using 5-fluorouracil, cisplatin, epidoxorubicin, 6S-leucovorin, glutathione and filgrastim: a report from the Italian Group for the Study of Digestive Tract Cancer (GISCAD).

Local extension prevents curative resection in more than two-thirds of gastric cancer patients. Unfortunately, resectability is one of the main prognostic factors in these patients, and survival is longer when tumours are completely removed. Preoperative chemotherapy is an attractive concept for obtaining curative resection. Thirty-two locally advanced unresectable gastric cancer patients were enrolled in five Italian Group for the Study of Digestive Tract Cancer (GISCAD) centres. For 16 patients, surgical unresectability was based on computerized tomography scan evaluation of tumour size (four patients) and invasion of adjacent structures (12 patients), whereas in another 16 patients locally advanced disease was confirmed by laparotomy. They received weekly administration of cisplatin 40 mg m(-2), 5-fluorouracil 500 mg m(-2), epidoxorubicin 35 mg m(-2), 6S-stereoisomer of leucovorin 250 mg m(-2) and glutathione 1.5 g m(-2). From the day after to the day before each chemotherapy administration, filgrastim was administered by subcutaneous injection at a dose of 5 microg kg(-1). One cycle of therapy consisted of eight weekly treatments. Fifteen of 32 patients (47%) responded to chemotherapy, whereas 13 (41 %) had stable disease and four (12%) progressed on therapy. Of the 15 responding patients, 13 were completely resected after chemotherapy and two of them had a complete pathological response. Two clinically responding patients were found unresectable at operation because of peritoneal seeding. At a median follow-up from the start of treatment of 24 months (range 11-39 months), 10 of 13 resected patients are alive and eight are relapse free. Three patients died after 11, 12, and 14 months respectively. Toxicity was acceptable: side-effects consisted mainly of grade II National Cancer Institute common toxicity criteria (NCICTC) leucopenia and thrombocytopenia in ten patients. Neither treatment-related death nor surgical complications in patients undergoing surgery were observed. This weekly intensive regimen enabled resection in half of previously inoperable tumours with a moderate toxicity. It can be offered to patients with locally advanced unresectable gastric cancer to obtain curative resection.

Phase I clinical trial of the bispecific antibody MDX-H210 (anti-FcgammaRI x anti-HER-2/neu) in combination with Filgrastim (G-CSF) for treatment of advanced breast cancer.

A phase I study of the bispecific antibody MDX-H210 in combination with granulocyte colony-stimulating factor (G-CSF) was performed in stage IV breast carcinoma patients, overexpressing HER-2/neu. MDX-H210, constructed by crosslinking antigen binding fragments (F(ab') fragments) of monoclonal antibody (mAb) H22 to Fc gamma receptor I (FcgammaRI), and mAb 520C9 to HER-2/neu, respectively, mediates the lysis of tumour cells in vitro, and in human FcgammaRI transgenic mouse models. The proto-oncogene HER-2/neu is overexpressed in approximately 30% of breast cancer patients, and represents a promising target for antibody-based immunotherapy. Fc gamma receptor I (CD64) is an effective trigger molecule, which is expressed on monocytes/macrophages, immature dendritic cells, and G-CSF-primed polymorphonuclear cells (PMN). Patients received G-CSF (Filgrastim) for 8 consecutive days, and cohorts of three patients were treated on day 4 with escalating, single doses of MDX-H210. A total of 30 patients were included, and treatment was generally well tolerated, without reaching dose-limiting toxicity. Side effects consisted mainly of fever and short periods of chills, which were timely related to elevated plasma levels of interleukin 6 and tumour necrosis factor alpha. In the last two cohorts, MDX-H210 plasma levels exceeded 1 microg ml(-1), and on circulating myeloid cells >50% saturation of FcgammaRI was found until day 4. These effector cells were highly effective in antibody-dependent cell-mediated cytotoxicity. Immunohistochemical analyses of tumour biopsies in individual patients documented infiltration of monocytes and PMN after MDX-H210 infusion. Although the clinical course of the disease was not altered by the single dose of MDX-H210, a favourable toxicity profile--even at high doses--and remarkable biological effects were seen when combined with G-CSF. Therefore, the combination of G-CSF and MDX-H210 should be evaluated in further immunotherapeutical strategies.

Influence of recombinant human granulocyte colony-stimulating factor (filgrastim) on hematopoietic recovery and outcome following allogeneic bone marrow transplantation (BMT) from volunteer unrelated donors.

Effects of recombinant human granulocyte colony-stimulating factor (rhG-CSF, filgrastim) on hematopoietic recovery and clinical outcome in patients undergoing allogeneic bone marrow transplantation (BMT) from volunteer unrelated donors (VUD) were analyzed retrospectively. Additionally, the influence of baseline patient and transplant characteristics on hematopoietic recovery was evaluated. From January 1994 to March 1996, 47 consecutive adult patients received VUD-BMT. GVHD prophylaxis was cyclosporin A/short course methotrexate/prednisolone, and in four patients additional ATG. Post-transplantation, cohorts of patients received rhG-CSF (5 microg/kg/day) (n = 22) or no rhG-CSF (n = 25) in a non-randomized manner. The patient groups with and without rhG-CSF were rather comparable with respect to baseline patient and transplant characteristics. Median time to neutrophil counts (ANC) >500/microl was 14 days with rhG-CSF vs 16 days without rhG-CSF (P = 0.048), to ANC >1000/microl was 15 vs 18 days (P = 0.084). Neutrophil recovery was accelerated in patients receiving more than the median MNC dose of 2.54 x 10(8)/kg with a median time to ANC >1000/microl of 13 days vs 19 days (P = 0.017). RhG-CSF did not influence platelet recovery and incidence of infectious complications. Incidence of acute GVHD II-IV was 50% with rhG-CSF and 28% without rhG-CSF (P = 0.144), but death before acute GVHD II-IV occurred in 9% of patients with and 20% of patients without rhG-CSF. The median follow-up time was 38 and 36 months in patients with and without rhG-CSF, respectively. Survival at 2 years post-transplant was 39% (95% confidence interval (18%, 60%)) in patients with rhG-CSF and 24% (95% confidence interval (7%, 41%)) in patients without rhG-CSF. Administration of rhG-CSF after VUD-BMT may lead to more rapid neutrophil recovery, but did not influence the incidence of infectious complications. Patients receiving rhG-CSF showed a slightly higher incidence of acute GVHD II-IV. Higher numbers of MNC in the marrow graft accelerated hematopoietic engraftment.

Repetitive high-dose therapy with cyclophosphamide, thiotepa and docetaxel with peripheral blood progenitor cell and filgrastim support for metastatic and locally advanced breast cancer: results of a phase I study.

This phase I study was designed to determine the optimal dosages of a novel repetitive high-dose therapy regimen for patients with metastatic breast cancer (MBC). The planned treatment was three cycles of high-dose cyclophosphamide, thiotepa and docetaxel delivered every 35 days with progressive dose-escalation in successive cohorts. Each cycle was supported by peripheral blood progenitor cells (PBPC) and filgrastim. Eighteen patients were entered into this trial. Of the planned 54 treatment cycles, 44 were delivered and 11 patients completed all three cycles. The dose-limiting toxicities were interstitial pneumonitis and mucositis with moderately severe diarrhea (n = 3) and rash (n = 3). There were no treatment-related deaths. Of the 17 patients with evaluable disease, 16 patients responded with six patients achieving a complete remission and an additional four patients achieving no detectable disease (negative restaging including PET scan) but a persistently abnormal bone scan. At a median follow-up of 12 months, median progression-free survival was 11 months with the median overall survival not reached. The recommended doses for phase II/III studies are cyclophosphamide (4 g/m2), thiotepa (300 mg/m2) and docetaxel (100 mg/m2).

Intermediate-dose melphalan (IDM) combined with G-CSF (filgrastim) is an effective and safe induction therapy for autologous stem cell transplantation in multiple myeloma.

Twenty-one previously untreated multiple myeloma (MM) patients and 10 previously treated patients with refractory or relapsed disease received two or three cycles of intermediate-dose melphalan (70 mg/m2) (IDM), administered intravenously every 6 weeks. Seven previously untreated patients received three and all other patients received two courses of IDM. The objective of the study was to reduce the toxicity of high-dose melphalan (140 mg/m2) (HDM) while maintaining its cytotoxic efficacy and secondly to ensure the possibility of collecting sufficient numbers of peripheral blood stem cells (PBSC) for transplantation. 18 (85%) previously untreated patients responded, of whom four achieved CR (18%). In addition five out of 10 previously treated patients with refractory or relapsed disease responded although bone marrow toxicity in this category was a major drawback. Toxicity was moderate, consisting of alopecia and moderate bone marrow suppression: the granulocyte count dropped below 0.5 x 10(9)/l and platelets below 25 x 10(9)/l for a median of 8 and 6 d, respectively. No serious infections occurred and the majority of patients attended the out-patient clinic. In 12/14 previously untreated patients sufficient peripheral blood CD34+ cells for harvest were present in the repopulation phase after the first IDM. In nine patients peripheral blood stem cells were collected and eight patients have undergone successful transplantation. Repeated IDM followed by filgrastim is highly effective in untreated MM and may be safely administered to reduce tumour load prior to PBSC collection. Autologous stem cells harvested after repeated IDM have a full long-term repopulating capacity.

Duration of filgrastim mobilization and apheresis yield of CD34+ progenitor cells and lymphoid subsets in normal donors for allogeneic transplantation.

Seventy-seven normal donors underwent leukapheresis for peripheral blood progenitor cell collection beginning on day 4 (n = 45) or day 5 (n = 32) of filgrastim mobilization (12 micrograms/kg/d). The two groups were comparable for age, weight, blood volumes processed during leukapheresis and target CD34+ cell dose to be collected. The day 5 schedule allowed a more consistent achievement of the target cell dose with one apheresis (P = 0.005) and resulted in the initial collection of a significantly larger number of CD34+ cells (P = 0.009). There was no statistically significant difference in the leukapheresis yield of lymphoid subsets and natural killer cells.

A comparative study of once-daily versus twice-daily filgrastim administration for the mobilization and collection of CD34+ peripheral blood progenitor cells in normal donors.

Eighty-one first-time normal donors underwent leukapheresis for peripheral blood progenitor cell (PBPC) collection after mobilization with filgrastim administered either twice-daily (6 microg/kg every 12 h; n = 40) or once-daily (12 microg/kg; n = 41) subcutaneously for 3 d. The groups were similar for age, donor blood volume and target CD34+ cell dose to be collected (>/= 4 x 106 CD34+ cells/kg recipient). There was no statistically significant difference in the apheresis yield of CD34+ PBPCs (x 106) per kg recipient weight (5.6 +/- 3.3 vs. 5.6 +/- 4.3; P = 0.94) and per litre of blood processed (30 +/- 17.2 vs. 30.4 +/- 19.5; P = 0.92).

The COBE Spectra cell separator is more effective than the Haemonetics MCS-3P cell separator for peripheral blood progenitor cell harvest after mobilization with cyclophosphamide and filgrastim.

BACKGROUND: Peripheral blood is rapidly replacing bone marrow as a source of hematopoietic progenitor cells for autologous transplantation. The advantages of peripheral blood progenitor cell transplantation are enhanced by the ability to collect sufficient progenitor cells to ensure rapid neutrophil and platelet recovery in a single procedure on some cell separators. STUDY DESIGN AND METHODS: A prospective randomized study was undertaken to compare peripheral blood progenitor cell yields from two cell separators (MCS-3P, Haemonetics and Spectra, COBE). Fifteen consecutive patients were mobilized with cyclophosphamide 2 g per m2 (Day 0) and filgrastim 10 micrograms per kg (Days 1-11). Consecutive collections (Day 10, Day 11) were performed with each machine once: patients were randomly assigned to either machine for the initial collection. RESULTS: Collection time was longer on the MCS-3P (p = 0.001), and the volume processed was greater with the Spectra (p < 0.0001). Despite similar nucleated cell yield (p = 0.62), the yield of CD34+ cells (p = 0.001) and colony-forming units-granulocytic-monocytic (p = 0.0001) was significantly higher with the Spectra. The yield of nucleated cells per unit of blood volume processed was higher for the MCS-3P (p = 0.0007), while the CD34+ cell yield (p = 1) and colony-forming units-granulocytic-monocytic yield (p = 1) per unit of blood volume processed were similar for the two machines. The collection of CD34+ cells at levels > 2 x 10(6) per kg (p = 0.063), 5 x 10(6) per kg (p = 0.031), and colony-forming units-granulocytic-monocytic > 1 x 10(5) per kg (p = 0.25) after a single collection was superior for the Spectra. CONCLUSION: The yield of progenitor cells after collection on the Spectra was superior to that achieved with the MCS-3P, because of the larger volume of blood processed per procedure. This would permit more patients to undergo only one collection.

Bronchiolitis obliterans organizing pneumonia in a patient with non-Hodgkin's lymphoma following R-CHOP and pegylated filgrastim.

Bronchiolitis obliterans organizing pneumonia (BOOP) presents with fever, dyspnoea, pleuritic chest pain and hypoxia. The diagnosis can be made from radiological appearances on chest radiograph and CT scan correlated with histological findings following biopsy. We present a 52-year-old gentleman undergoing treatment for high grade non-Hodgkin's lymphoma who developed respiratory symptoms during chemotherapy. BOOP was diagnosed and he responded well to oral prednisolone. The cause of BOOP is often not certain. However, in this case we suspect pegylated filgrastim or rituximab as possible agents.

Dose escalation of high-dose cyclophosphamide and etoposide with high-dose doxorubicin (CDE) and filgrastim for poor-risk non-Hodgkin's lymphoma.

PURPOSE: To identify the highest possible dose of cyclophosphamide (C) and etoposide (E) to be given with high-dose doxorubicin (D) and filgrastim (G-CSF) but without stem cell support in high-risk non-Hodgkin's lymphoma. PATIENTS AND METHODS: High-dose CDE was given to 18 evaluable patients, 5 had previous chemotherapy. All patients received D 90 mg/sqm and G-CSF 20 micrograms/kg/day. The first cohort had C 1800 mg/sqm and E 450 mg/sqm. Chemotherapy was given in equally divided doses over three days. Dose escalation was performed thrice up to C 3900 mg/sqm and E 975 mg/sqm. One to four courses were given. RESULTS: The median number of days (quartile values) with neutrophils < 0.5 x 10(9)/l was 9 days (7-10), untransfused platelets < 20 x 10(9)/l 6 days (3-7), fever > or = 38 degrees C 5 days (3-8), intravenous antibiotics 10 days (9-12), with packed red cell transfusion 1 day (0-2), and with platelet transfusion 2 days (1-3). Six patients had complete remission and 11 partial remission from first course. There was no difference in toxicity according to dose level. A second course was given to 15 patients, resulting in fewer days with neutropenia (mean 7.2), and intravenous antibiotics (mean 6.3). Mucositis was the main non-hematologic toxicity. CONCLUSIONS: Very high-dose CDE with G-CSF but without stem cell support is feasible as primary therapy. The toxicity was similar to that of standard autologous stem cell transplantation programs.

Paclitaxel plus gallium nitrate and filgrastim in patients with refractory malignancies: a phase I trial.

To determine the maximally tolerated dose of paclitaxel with and without filgrastim (G-CSF) when administered as a 24-hour intravenous infusion after a 120-hour infusion of gallium nitrate at a fixed dose of 300 mg/m2/24 hours, 40 patients were entered onto a trial lasting from September 1994 to September 1996. Eligibility included a diagnosis of an advanced malignancy not amenable to curative therapy and up to one previous chemotherapy regimen for metastatic disease. Gallium was administered at a fixed dose of 300 mg/m2/day as a continuous intravenous infusion for 120 hours. Paclitaxel starting at 90 mg/m2 was given concurrently with the last 24 hours of the gallium as a 24-hour intravenous infusion. Cycles were repeated every 21 days. Once the maximum tolerated dose (MTD) of paclitaxel was reached, G-CSF (5 microg/kg/day days 7-16) was added and paclitaxel dose escalation continued. The MTD for paclitaxel without G-CSF was 110 mg/m2 and 225 mg/m2 with G-CSF, with neutropenia being the dose-limiting toxicity. A partial response was noted in a patient who had thymoma and a complete response was achieved in a patient who had colon cancer. The recommended phase II dosage is gallium nitrate at 300 mg/m2/day over 120 hours, with paclitaxel at 110 mg/m2 over 24 hours without G-CSF or 225 mg/m2 over 24 hours with G-CSF and 0.5 mg calcitriol on days 1 through 7. Further trials of this modified regimen for outpatient administration are in progress.

Efficacy of carboplatin plus primary prophylactic filgrastim (granulocyte colony stimulating factor) in relapsed ovarian cancer: a study of the Gynecologic Oncology Group of the Comprehensive Cancer Center Limburg.

A total of 34 patients with advanced ovarian cancer, who relapsed 1-72 months after at least one first-line cisplatin-based chemotherapy protocol, were treated with carboplatin, 350 mg/m2 q 4 weeks, with the adjunct of primary prophylactic granulocyte colony stimulating factor (G-CSF; filgrastim), 300 or 480 microg daily, days 5-9. Over 90% of the anticipated dose of carboplatin could be administered. Partial response, defined as a decline in CA-125 of 50% or more on two consecutive samples, occurred in 42%, while 15% of patients achieved a complete response (no clinical signs of disease with normalization of CA-125). Survival from start of carboplatin treatment was 23 months. Myelosuppression was the most important toxicity with 35% of patients experiencing grade 4 thrombocytopenia of short duration. Grade 4 leucopenia occurred in only one patient. It is concluded that single-agent carboplatin, with the adjunct of prophylactic G-CSF, can be administered with adequate dose intensity, and is an effective and acceptable palliative treatment for patients with relapse after first-line cisplatin-based chemotherapy.

Neo-adjuvant therapy with dose-dense docetaxel plus short-term filgrastim rescue for locally advanced breast cancer.

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.

Marginal keratitis associated with administration of filgrastim and sargramostim in a healthy peripheral blood progenitor cell donor.

PURPOSE: To describe a 61-year-old healthy peripheral blood progenitor cell (PBPC) donor who developed marginal keratitis and mild uveitis on the third day after receiving daily recombinant human granulocyte colony-stimulating factor (rhG-CSF; filgrastim) and recombinant human granulocyte-macrophage colony-stimulating factor (rhGM-CSF; sargramostim) to mobilize PBPCs for allogeneic transplantation. METHODS: Interventional case report. RESULTS: The keratitis was treated with topical administration of 1% prednisolone acetate solution and resolved within 24 hours. The topical steroid dose was tapered and ultimately discontinued without recurrence of keratitis. CONCLUSION: Healthy PBPC donors receiving rhG-CSF or rhGM-CSF should be monitored for ocular complications, particularly marginal keratitis and uveitis.

Increased dose density is feasible: a pilot study of adjuvant epirubicin and cyclophosphamide followed by paclitaxel, at 10- or 11-day intervals with filgrastim support in women with breast cancer.

PURPOSE: Because Cancer and Leukemia Group B 9741 trial showed a benefit for every 14-day administration of chemotherapy compared with every 21-day treatment, we hypothesized that even greater dose density would be more effective. We conducted a pilot trial to assess the feasibility of dose-dense chemotherapy consisting of a standard regime at 10- to 11-day intervals in the adjuvant/neoadjuvant setting. A 2-day window was allowed for scheduling logistics. EXPERIMENTAL DESIGN: Thirty-nine women with early-stage breast carcinoma were accrued from April 2004 to October 2004. Median age was 47 years (range, 26-67 years). Patients received therapy with 100 mg/m(2) epirubicin and 600 mg/m(2) cyclophosphamide (EC) q 10 to 11 days for four cycles followed by 175 mg/m(2) paclitaxel q 10 to 11 days for four cycles, all with filgrastim support (300 microg s.c. daily) from day 2 to 24 h before the next treatment. RESULTS: Thirty-five (90%) patients completed all planned therapy. The median intertreatment interval was 10 days (range, 8-28 days). Cycles (80.7%) were delivered at no more than 10- to 11-day intervals. There were five dose reductions of 25% for grade 3 nonhematologic toxicity in five patients. Six (16%) patients developed febrile neutropenia defined as temperature >38 degrees C with absolute neutrophil count <1,000/microL. All febrile neutropenia was during therapy with EC. Other grade 3 toxicities included bone pain, hand and foot syndrome, neuropathy, mucositis, nausea, and vomiting. CONCLUSIONS: Therapy with EC for four cycles followed by paclitaxel for four cycles at 10- to 11-day intervals is feasible. The approximately 30% reduction in intertreatment interval compared with every 14-day treatment could increase the efficacy of adjuvant chemotherapy.

A pilot clinical trial of postoperative intensive weekly chemotherapy using cisplatin, epi-doxorubicin, 5-fluorouracil, 6S-leucovorin, glutathione and filgrastim in patients with resected gastric cancer.

AIMS AND BACKGROUND: The study was performed to assess the feasibility and activity of an intensive chemotherapeutic regimen as adjuvant treatment for patients with resected gastric cancer at high risk of recurrence (pT(2)N(1-2); pT(3-4)N(any) M0). PATIENTS AND METHODS: Starting 21 to 28 days after potentially curative surgery for primary gastric cancer, 25 patients received 8 weekly cycles of cisplatin 40 mg/m2, 5-fluorouracil 500 mg/m2, epidoxorubicin 35 mg/m2, 6S-stereoisomer of leucovorin at a dose of 250 mg/m2, and glutathione at a dose of 1.5 g/m2. From the day after to the day before each cycle of chemotherapy, filgrastim was administered by subcutaneous injection at a dose of 5 microg/kg. RESULTS: After a median follow-up of 33 months, 80% of the patients were alive and disease-free. Five patients had relapsed: three in the liver, one in the peritoneum and one in the lymph nodes. Toxicity was mild: five patients experienced WHO grade III toxicity (three leukopenia, two thrombocytopenia); no toxic deaths occurred. CONCLUSION: Intensive weekly chemotherapy is a feasible postoperative treatment option for patients with resected gastric cancer at high risk of relapse. These data, together with recent results in advanced disease, make this approach of interest for the development of new programs of adjuvant therapy in this setting.
