Idiopathic pneumonia syndrome after high-dose chemotherapy for relapsed Hodgkin's disease.

The risk of idiopathic pneumonia syndrome (IPS) in patients with Hodgkin's disease (HD) undergoing high-dose chemotherapy (HDC) is significant, and once developed IPS is potentially fatal. The aim of this study was to quantify this risk accurately and determine prognostic factors for its development and course. Using a computerized database, all patients with HD treated with BCNU (carmustine) containing HDC and haematopoietic support at The Royal Marsden between November 1985 and March 1994 were identified. Patient characteristics, previous treatments, disease status at HDC, dose of BCNU, incidence and severity of IPS and survival were all determined and analysed. During the study period, 94 patients received HDC, of whom 26 (28%) had a first episode of IPS within a year of HDC and 23 within 6 months. The median time to presentation after HDC was 93 days (range 12-336 days). The only factors that significantly increased the risk of developing IPS on multivariate analysis were dose of BCNU (P for trend = 0.03) and female sex (P = 0.04). Of these 26 patients, 14 had complete resolution of all symptoms, three had persisting pulmonary symptoms at 6 months and the remaining nine died of IPS at a median of 74 days (19-418 days). All the patients who died from IPS had the first symptoms within 6 months of HDC and all received doses of BCNU > 475 mg m(-2) (P for trend = 0.001). For women receiving > 475 mg m(-2) the risk of death was significantly higher than for men (P = 0.035) but not for those receiving < 475 mg m(-2). Previous lung disease, persisting residual disease before HDC, previous bleomycin or previous mantle radiotherapy did not increase either the incidence of IPS or risk of a fatal outcome. We conclude that the main avoidable risk factor for fatal IPS after HDC is dose of BCNU, and this is especially true for women. If < 475 mg m(-2) is given, even patients with previous mantle radiotherapy and/or previous bleomycin have a very low risk of developing fatal lung toxicity if lung function tests are normal.

DNA interstrand cross-linking and cytotoxicity induced by chloroethylnitrosoureas and cisplatin in human glioma cell lines which vary in cellular concentration of O6-alkylguanine-DNA alkyltransferase.

Fifteen human glioma cell lines were examined for their sensitivity to 1,3-bis(chloroethyl)-nitrosourea (BCNU, carmustine) and cis-dichlorodiamminoplatinum (cisplatin), the induction of DNA interstrand cross-linking (DNA-ISC) induced by the two agents and cellular O6-alkylguanine alkyltransferase (ATase) activity. Cell lines differed in their sensitivities to BCNU by up to 12-fold and to cisplatin by up to 21-fold. For both drugs, the extent of DNA-ISC was related to the drug sensitivity. There was a wide range of cellular ATase levels. Increasing ATase levels correlated with increased resistance to BCNU and with decreased formation of DNA-ISC following treatment with BCNU. In contrast, following treatment with cisplatin, there was no correlation between cellular ATase content and cytotoxicity or between ATase and DNA-ISC. Four sublines of varying ATase activity were prepared from one of the cell lines. These sublines showed a sensitivity to BCNU in inverse proportion to ATase activity, while sensitivity to cisplatin was more uniform. The experiments confirm the direct relationship between ATase concentration and sensitivity to BCNU in glioma cells. Although there was some correlation between cisplatin cytotoxicity and BCNU cytotoxicity, this was not mediated through ATase.

Combination chemotherapy with or without s.c. IL-2 and IFN-alpha: results of a prospectively randomized trial of the Cooperative Advanced Malignant Melanoma Chemoimmunotherapy Group (ACIMM).

The purpose of this randomized trial was to evaluate the efficacy of combination chemoimmunotherapy compared with chemotherapy alone. A total of 124 patients were randomized to receive intravenous cisplatin (35 mg m(-2), days 1-3), carmustine (150 mg m(-2), day 1, cycles 1 and 3 only), dacarbacine (220 mg m(-2), days 1-3) and oral tamoxifen (20 mg m(-2), daily) in combination with (n=64) or without (n=60) sequential subcutaneous IL-2 and IFN-alpha. In those patients who received sequential immunotherapy, each cycle of chemotherapy was followed by outpatient s.c. IL-2 (10 x 10(6) IU m(-2), days 3-5, week 4; 5 x 10(6) IU m(-2), days 1, 3, 5, week 5) and s.c. IFN-alpha (5 x 10(6) IU m(-2), day 1, week 4; days 1, 3, 5, week 5). The overall response rate of patients treated with the combination of chemotherapy and IL-2/IFN-alpha was 34.3% with seven complete responses (10.9%) and 15 partial responses (23.4%). In patients treated with chemotherapy, only, the overall response rate was 29.9% with eight complete responses (13.3%) and 10 partial responses (16.6%). There was no significant difference in median progression free survival (0 months vs 4 months) and in median overall survival (12 months vs 13 months) for combined chemoimmunotherapy and for chemotherapy, respectively.

Autotransplantation for relapsed or refractory Hodgkin's disease: long-term follow-up and analysis of prognostic factors.

Seventy consecutive patients with refractory or relapsed Hodgkin's disease who received high-dose chemotherapy followed by autologous stem cell rescue were analyzed to identify clinically relevant predictors of long-term event-free survival. High-dose therapy consisted primarily of carmustine (BCNU), etoposide, cytarabine and cyclophosphamide (BEAC). The 5-year Kaplan-Meier event-free survival (EFS) for the entire cohort was 32% (95% confidence interval; 18-45%) with a median follow-up of 3.6 years (range 7 months-7.6 years). The most significant predictor of improved survival was the presence of minimal disease (defined as all areas < or =2 cm) at the time of transplant: the 5 years EFS was 46 vs 10% for patients with bulky disease (P = 0.0002). Other independent predictors identified by step-wise regression analysis included the presence of non-refractory disease and the administration of post-transplant involved-field radiotherapy (XRT). Treatment-related mortality occurred in 13 of 70 patients: nine patients (13%) died within the first 100 days, mainly from cardiopulmonary toxicity. However, only one of 24 patients (4%) transplanted during the last 4.5 years died from early treatment-related complications. While high-dose therapy followed by autotransplantation led to long-term EFS of 50% for patients with favorable prognostic factors, a substantial proportion of patients relapsed, indicating that new therapeutic strategies are needed.

Previous treatment predicts the efficiency of blood progenitor cell mobilisation: validation of a chemotherapy scoring system.

Following mobilising chemotherapy and myeloid growth factors, some heavily pretreated patients do not mobilise adequate numbers of peripheral blood progenitor cells (PBPC). It would be clinically useful to identify such patients in advance. A recent scoring system based on previous therapy may be useful in predicting CD34-positive cell yield. In this study we validated this scoring system on an independent group of 99 patients undergoing 103 harvesting episodes. In 61 patients mobilised with cyclophosphamide 1.5 g/m2 and G-CSF, those with treatment scores less than 21 yielded significantly more CD34-positive cells than patients with scores greater than 63 (P = 0.0012). Previous treatment with melphalan or carmustine was associated with a significantly lower yield of CD34-positive cells (P= 0.0001). No relationship was seen between the time from previous chemoradiotherapy and harvest outcome. Patients with treatment scores less than 21 required a shorter duration of G-CSF therapy (P = 0.05). Similar findings were seen in 42 further mobilisation cycles undertaken with alternative mobilisation schedules. The present data suggest that a score summarising previous treatment can be used to predict CD34 yields, and could be of clinical use to identify poor PBPC mobilisers in advance.

Prognostic factors for the clinical outcome of patients with follicular lymphoma following high-dose therapy and peripheral blood stem cell transplantation (PBSCT).

This is a report on 111 patients with advanced stage follicular lymphoma who where autografted using PBSC. Seventy patients were enrolled in first remission, whereas 41 were treated in second or higher remission. High-dose therapy consisted of total body irradiation plus cyclophosphamide in 103 patients, while eight patients received BEAM (carmustine, etoposide, cytosine-arabinoside, melphalan). Autografts contained 8.1 +/- 0.6 x 106 CD34+ cells/kg body weight. At a median follow-up of 44.2 months from PBSCT (range 4.9-77.4 months), 93 patients are alive, with a probability of overall and relapse-free survival (RFS) of 83% and 64%, respectively. A significantly higher probability of relapse was associated with male gender, involvement of more than eight lymph node areas, extra-nodal manifestations other than bone marrow and PBSCT performed in second or higher remission. In the latter group of patients, previous radiotherapy was associated with poor prognosis. The relevance of chemosensitivity as a prognostic factor was reflected by a better RFS in patients who had achieved complete remission at the time of PBSC mobilization. In a multivariate analysis, involvement of eight or more lymph nodes and high-dose therapy performed in second or higher remission were independent prognostic factors.

Cardiac sequelae of doxorubicin and paclitaxel as induction chemotherapy prior to high-dose chemotherapy and peripheral blood progenitor cell transplantation in women with high-risk primary or metastatic breast cancer.

Doxorubicin plus paclitaxel has been shown to be an active regimen for metastatic breast cancer and is now frequently used as adjuvant therapy for high-risk primary breast cancer. Initial studies reported a higher than expected rate of cardiac toxicity with this regimen. We studied 105 patients with either high-risk primary breast cancer or metastatic breast cancer who were treated with doxorubicin (60 mg/m2) and 3-h infusions of paclitaxel (175 mg/m2) cycled every 3 weeks. Patients received three cycles of chemotherapy for high-risk primary or four cycles for metastatic disease. Patients then proceeded to high-dose chemotherapy (HDC) (STAMP I cyclophosphamide, cisplatin and carmustine) and peripheral blood progenitor cell transplantation (PBPCT). Patients underwent radionuclide multi-gated angiograms (MUGA) before and following induction chemotherapy and following HDC. During induction chemotherapy 40 (38%) of the patients had a reduction in left ventricular ejection fraction (LVEF). Fourteen had a decrease of 20% or greater and two were mildly symptomatic from CHF. There was additional reduction in the LVEF after HDC with a median value for LVEF of 59% (range, 20-78%). During HDC 10 patients developed clinical signs of congestive heart failure (CHF). Five patients responded to diuretic therapy and did not require any additional treatment. Four patients responded to vasodilation and/or digoxin with improvement in cardiac function. A clinically significant decrease in cardiac function was found in a small number of patients after induction chemotherapy and HDC with PBPCT. The majority of the patients tolerated this regimen without problems. Although there was a decline in LVEF as measured by radionuclide MUGA this did not prevent the majority of patients from proceeding with HDC. Bone Marrow Transplantation (2000).

Pulmonary toxicity syndrome following CDEP (cyclophosphamide, dexamethasone, etoposide, cisplatin) chemotherapy.

We report on three patients with multiple myeloma who developed drug-induced pneumonitis 1-2(1/2) months following maintenance (post autologous transplantation) chemotherapy with CDEP (cyclophosphamide, dexamethasone, etoposide, cisplatin) and 6-20 months after exposure to carmustine (BCNU) 300 mg/m(2), used in combination with melphalan 140 mg/m(2), as pre-transplant conditioning regimen. All patients had either a proven (two) or suspected (one) fungal pneumonia and were treated with liposomal amphotericin B. Dyspnea, fever and cough were the prominent clinical symptoms, while air-space disease with ground glass appearance was seen radiographically. Histologic features typical for drug-induced lung injury were detected. All patients had a dramatic, clinical and radiographic response to a brief course of corticosteroids. Although CDEP-induced pneumonitis appears to be a rare complication, its early recognition and prompt treatment, as well as its possible association with preceding fungal infection may have important clinical implications.

Interferon-gamma for delayed pulmonary toxicity syndrome resistant to steroids.

Delayed pulmonary toxicity syndrome, characterized by interstitial pneumonia and pulmonary fibrosis, is common following high-dose bischloroethylnitrosourea (BCNU) (carmustine, [1,3-bis (2-chloroethyl)-1-nitrosourea]) containing chemotherapeutic regimens. Depending upon the treatment protocol, it may develop in over 70% of patients. Early and aggressive corticosteroid treatment leads to improvement in the majority of patients. However, up to 8% of affected patients may fail to respond to corticosteroids and develop progressive respiratory failure leading to death. No alternatives to corticosteroids have thus far been shown useful. We report the symptomatic and physiological improvement of a patient with severe steroid-resistant delayed pulmonary toxicity syndrome, following treatment with interferon-gamma.

Idiopathic pneumonia syndrome after high-dose chemotherapy and autologous hematopoietic stem cell transplantation for high-risk breast cancer.

Our aim was to describe the incidence, clinical course, and risk factors for idiopathic pneumonia syndrome (IPS) after high-dose chemotherapy with cyclophosphamide, carmustine, and thiotepa followed by autologous stem cell transplantation for high-risk breast cancer. Charts for patients who underwent high-dose chemotherapy for high-risk breast cancer at a single center from 1992 to 2000 were retrospectively reviewed, and potential risk factors for development of IPS were sought with the log-rank test. Of 164 patients reviewed, 20 developed IPS at a median onset of 87 days after the transplant (range, 2-257 days). The actuarial incidence of IPS in the first 100 days after the transplant was 8%, and 95% of patients developed symptoms within the first 6 months after transplant. Patient age, smoking status, breast cancer stage at diagnosis, and pretransplant lung function did not predict development of IPS. Three patients died of progressive pulmonary failure and the IPS resolved in the other 17. We concluded that IPS is an important cause of morbidity and mortality in patients with high-risk breast cancer undergoing high-dose chemotherapy. Given the absence of predictive factors, any pulmonary symptoms appearing in the first year after the transplant should be evaluated carefully.

High-dose chemotherapy and autologous peripheral blood stem cell transplantation for primary breast cancer refractory to neoadjuvant chemotherapy.

The role of high-dose chemotherapy (HDCT) in patients with refractory breast cancer is not well established. Forty-two female patients (median age of 46 years) with breast cancer refractory to neoadjuvant chemotherapy received HDCT (cyclophosphamide, carmustine and thiotepa) supported by an autologous peripheral blood stem cells transplant. Their disease had been refractory (defined as less than partial response) to one (18 patients) or two (24 patients) regimens of neoadjuvant chemotherapy. Twenty-nine patients had surgery before HDCT. The best response after surgery, HDCT, and radiation therapy was assessed 60 days after transplantation. Thirty patients had complete remission, eight had a PR, one had a minor response, and three had progressive disease. In seven of 13 patients whose disease was inoperable before HDCT, it became operable. After a median follow-up of 42 months, 21 patients were alive, and 15 remained disease free. Five-year overall survival (OS) was 57% (CI, 50-64%), and the estimated 5-year progression-free survival was 40% (CI, 32-48%). Both OS and PFS were better in patients whose disease became operable after chemotherapy than in those whose disease remained inoperable. A randomized study is warranted in this patient population.

High risk of therapy-related leukemia after BEAM chemotherapy and autologous stem cell transplantation for previously treated lymphomas is mainly related to primary chemotherapy and not to the BEAM-transplantation procedure.

A cohort of 76 patients with previous chemotherapy for Hodgkin's disease and non-Hodgkin lymphomas received high-dose carmustine, etoposide, cytosine-arabinoside and melphalan (BEAM) followed by autologous stem cell transplantation (ASCT) and was followed for relapse and development of leukemic complications. Six patients, four with Hodgkin's disease and two with non-Hodgkin lymphomas, developed leukemic complications, myelodysplasia (MDS) in four cases and overt acute myeloid leukemia (AML) in two. All six showed an abnormal karyotype, in four of them highly characteristic of therapy-related MDS (t-MDS) and therapy-related AML (t-AML). The cumulative risk of t-MDS and t-AML increased from 16 months after start of the primary chemotherapy for lymphoma and reached 17.3% (s.e. 8.5%) after 74 months. If calculated from start of BEAM and ASCT, the cumulative risk increased as early as 4 months and reached 24.3% (s.e. 12.9%) after 43 months. For the whole course of the disease, the relative risk (RR) of AML was 357 (95% CI: 43-1290), as two overt leukemias were observed vs 0.0056 expected cases of de novo AML. In the present cohort the risk of t-MDS and t-AML although high, did not differ from our previous experience in patients treated conventionally for Hodgkin's disease and non-Hodgkin lymphomas, and did not differ for patients receiving stem cells isolated from the bone marrow as compared to patients receiving stem cells isolated from peripheral blood. Antecedent chemotherapy seems to be the critical factor for the development of t-MDS and t-AML rather than the BEAM and ASCT regimen, which however may accelerate the evolution of the disease.

A long-term follow-up of 33 patients with non-Hodgkin's lymphoma who received the BEAM high-dose intensification regimen with cytokine support only and no transplant.

High-dose intensification and autologous stem-cell transplantation (ASCT) is widely used to consolidate patients with non-Hodgkin's lymphoma (NHL), who have reached a stage of minimal residual disease. However, patients with persisting marrow and/or blood involvement and those who fail peripheral blood hemopoietic progenitor mobilization are excluded from ASCT. For such patients with no available graft to infuse, we developed 15 years ago, before the anti-CD20 monoclonal antibody therapeutic era, the use of the BEAM pretransplant regimen followed only by the administration of three cytokines (erythropoietin, granulocyte colony-stimulating factor, granulocyte-macrophage colony-stimulating factor). We report here on the long-term follow-up of 33 patients treated with this approach. In all, 33 NHL patients underwent the BEAM (carmustine, VP-16, cytosine-arabinoside, melphalan) followed by the administration of the three cytokines from January 1994-2000. A backup marrow, albeit infiltrated by tumor cells, had been collected earlier and stored in all. A total of 30 patients (91%) recovered normal hematopoiesis. In total, 32 patients (97%) recovered neutrophils (>500/microl) at a median of 19 days and 30 patients (91%) recovered platelets (>20,000/microl) at a median of 26 days. Age, richness of backup graft and blood-hemoglobin level at intensification had an impact on the time for hematopoietic recovery (P=0.014, P=0.014, P=0.048). The median follow-up was 62 months. Five patients died from toxicity related to the procedure. Eight patients relapsed and died. A total of 20 patients (61%) are alive, 16 (49%) in complete remission. A 5-year disease-free survival was 52+/-9%, relapse incidence 35+/-16%, mortality due to the procedure 12+/-12% and overall survival 61+/-10%. The BEAM regimen is not myeloablative. The BEAM+3CK procedure is a feasible therapeutic option that has shown efficacy in poor risk NHL patients who were not eligible for autografting because of persisting marrow/blood tumor contamination, or poor hemopoietic progenitor harvesting. It is unclear today whether some of these patients would have cleared their marrow/peripheral blood with the additional use of anti-CD20 treatment, thereby making the classical approach (BEAM followed by the infusion of a clean autograft) feasible.

Long-term follow-up in patients treated with Mini-BEAM as salvage therapy for relapsed or refractory Hodgkin's disease.

Several studies have focused on investigation of the optimal salvage regimen to induce maximum response before autologous stem cell transplantation (ASCT) in patients with relapsed or refractory Hodgkin's disease (HD). However, in most of these studies, the follow-up is relatively short. In the present study, we report on long-term results of 55 consecutive patients with HD who received Mini-BEAM [BCNU (carmustine), etoposide, cytarabine, melphalan] as salvage therapy before ASCT. Eleven patients were refractory to front-line therapy, 17 were partial responders, and 27 patients had relapsed from HD. Twenty-eight patients achieved complete response, and 18 achieved partial response with a median of two cycles of Mini-BEAM, giving a total response rate of 84%. Significant factors predicting poor response (P < 0.05) were: initial treatment with MOPP (mechloroethamine, oncovin, procarbazine, prednisolone), > or = two previous chemotherapy regimens and three disease characteristics at Mini-BEAM treatment: presence of B symptoms, extranodal involvement or low serum albumin. However, only the last two factors retained independent influence on multivariate analysis. In total, 45/55 patients have been transplanted. Median follow-up after Mini-BEAM administration for living patients is 68 months. At the time of reporting, 31 out of 55 patients (56.4%) are still alive, 21 patients (38%) have relapsed, three (5.4%) have developed secondary neoplasias, and five have died of other complications not related to disease progression. The actuarial 7-year overall survival (OS) was 52%, the progression-free survival (PFS) 54% and the event-free survival (EFS) 36%. The response to Mini-BEAM was the most important prognostic factor for predicting the long-term probability of surviving the disease: none of the eight patients who did not respond to Mini-BEAM were alive at 3 years. On multivariate analysis, response to Mini-BEAM and extranodal involvement before Mini-BEAM had a significant influence on OS. Our results show the safety and efficacy of Mini-BEAM before ASCT for refractory or relapsed HD patients.

Increased excitability and decreased sensitivity to GABA in an animal model of dysplastic cortex.

PURPOSE: Cortical dysplasia (CD) is associated with epilepsy in both the pediatric and adult populations. The mechanism underlying seizures with cortical malformations is still poorly understood. To study the physiology of dysplastic cortex, we developed an experimental model of CD. METHODS: Pregnant rats were given intraperitoneal injections of carmustine (1-3-bis-chloroethyl-nitrosourea; BCNU) on embryonic day 15 (E15). Cortical histology was examined in the resulting pups at P0, P28, and P60. In addition, evoked and spontaneous field potential recordings were obtained in cortical slices from adult control and BCNU-exposed rats. Finally, we used whole-cell recordings to compare physiologic properties of pyramidal neurons and gamma-aminobutyric acid (GABA) responses in control and BCNU-treated animals. RESULTS: Features characteristic of CD were found in the offspring, including laminar disorganization, cytomegalic neurons, and neuronal heterotopias. Dysplastic cortex also contained abnormal clusters of Cajal-Retzius (CR) cells and disruption of radial glial fibers, as demonstrated with immunohistochemistry. Under conditions of partial GABAA-receptor blockade with 10 microM bicuculline methiodide (BMI), slices of dysplastic cortex demonstrated a significant increase in the number of spontaneous and evoked epileptiform discharges. Individual pyramidal neurons in dysplastic cortex were less sensitive to application of GABA compared with controls. CONCLUSIONS: BCNU exposure in utero produces histologic alterations suggestive of CD in rat offspring. Dysplastic cortex from this model demonstrates features of hyperexcitability and decreased neuronal sensitivity to GABA. Such physiologic alterations may underlie the increased epileptogenicity of dysplastic cortex.

High-dose therapy and autologous hematopoietic-cell transplantation for follicular lymphoma beyond first remission: the Stanford University experience.

A retrospective analysis was performed to investigate the outcome of high-dose therapy (HDT) and autologous hematopoietic cell transplantation in patients with follicular lymphomas beyond first remission. Ninety-two patients with primary induction failure or relapsed follicular low-grade lymphoma (FLGL), follicular large cell lymphoma (FLCL), and transformed follicular lymphoma (TFL) were treated with myeloablative therapy consisting of etoposide (60 mg/kg), cyclophosphamide (100 mg/kg), and either carmustine (BCNU;15 mg/kg) or fractionated total body irradiation (FTBI; 1200 cGy) followed by transplantation of purged autologous bone marrow or peripheral blood hematopoietic cells. For the 49 patients with relapsed FLGL, the median age was 49 years and the median interval from diagnosis to HDT was 30 months. The 4-year estimate of overall survival (OS) was 60% (95% confidence interval [CI], 45%-75%) and of disease-free survival (DFS) was 44% (95% CI, 29%-59%). Treatment with the FTBI-containing HDT regimen was associated with significantly longer DFS (P = .04) and OS (P = .04) in our multivariate analysis. OS was also significantly longer among those treated with 3 or fewer chemotherapy regimens. For the 26 FLCL patients, the median age was 51 years and in 31% the indication for HDT was primary induction failure. For FLCL patients, the 4-year estimate of OS was 58% (95% CI, 37%-79%) and of DFS was 51% (95% CI, 30%-72%). Among the 17 patients with TFL, 13 (76%) transformed at first relapse, and only 6 patients (35%) achieved complete remission with salvage therapy prior to HDT. For TFL patients, the 4-year estimate of OS was 50% (95% CI, 24%-76%) and of DFS 49% (95% CI, 20%-78%). There were 3 occurrences of myelodysplasia (1 after treatment with TBI, 2 after BCNU treatment), yielding an estimated incidence of 7% (95% CI, 0%-16%) at 56 months. This analysis shows that relapsed FLGL patients treated with 3 or fewer different chemotherapy regimens show inferior survival. The HDT regimen containing FTBI appears to be superior to the BCNU-based regimen for relapsed FLGL, although longer follow-up is needed to evaluate late effects. Lastly, patients with TFL or induction failure and relapsed FLCL can achieve survival outcome comparable to those observed with the indolent follicular lymphomas.

High-dose chemotherapy and hematopoietic support for patients with high-risk primary breast cancer and involvement of 4 to 9 lymph nodes.

Despite modern chemotherapy, advanced breast cancer remains a significant cause of cancer morbidity and mortality in women. Patients with disease involvement of multiple lymph nodes represent a subgroup with a high risk of relapse. In particular, 50% of patients with 4 to 9 axillary lymph nodes involved will relapse after standard chemotherapy. In an effort to improve the survival of patients with 4 to 9 involved nodes, we performed a phase II study in which 61 patients with surgically diagnosed stage II or III breast cancer and 4 to 9 positive lymph nodes received 3 cycles of doxorubicin and 5-fluorouracil followed by high-dose chemotherapy consisting of cisplatin, cyclophosphamide, and carmustine and infusion of autologous hematopoietic progenitor cells. All patients received posttransplantation localized radiotherapy unless contraindicated, and all patients with hormone receptor-positive disease received tamoxifen. After a median patient follow-up of 6.7 years (range, 4.6-8.6 years), the 5-year overall survival rate was 79% (95% CI, 69%-90%), with relapse-free survival of 73% (95% CI, 62%-85%). Treatment-related mortality was 3%. Interstitial pneumonitis occurred in 69% of patients but did not contribute to mortality. Our study presents long-term favorable results regarding the use of consolidative HDC with autologous hematopoietic support in previously untreated patients with high-risk primary breast cancer.
