Abstract
Drug resistance is a major problem in the treatment of solid tumours. Based on a steep dose-response relationship for especially alkylating agents on tumour cell survival, high-dose chemotherapy was considered of interest for the treatment of solid tumours. Results of phase 1 and 2 studies with high-dose chemotherapy in a variety of tumour types showed good response rates. Nowadays, several phase 3 studies are available especially in metastatic and high-risk breast cancer patients. The high expectations of high-dose chemotherapy did not come true. This review analyses results of randomised studies and comments on the discrepancy between findings in patients versus those in tissue culture. Potential factors involved are the presence of tumour stem cells with different characteristics from more mature tumour cells, limitations in drug escalation in the clinic, transplant mortality, trial design and tumour cell contamination of the haematopoietic stem cell transplant. Maturation of the results from recent studies indicating a more modest benefit in, e.g., adjuvant breast cancer balanced versus long-term side effects will ultimately determine the role of high-dose chemotherapy in certain solid tumours. In case of well-defined indications for high-dose chemotherapy, further selection of patients based on patient and tumour characteristics as well as the introduction of new agents will most likely play a role.

Abstract
BACKGROUND The purpose of this study was to assess whether a short course of anthracycline containing chemotherapy followed by high dose therapy with autologous stem-cell support improves disease-free and overall survival as compared with conventional, anthracycline containing chemotherapy, in patients with primary breast cancer and four or more histologically involved lymph nodes. PATIENTS AND METHODS Two hundred and eighty one patients entered into a randomised clinical trial were allocated to receive standard, conventional treatment (5-fluorouracil, epirubicin and cyclophosphamide-FEC for six cycles) or FEC for three cycles followed by high dose therapy consisting of cyclophosphamide, thiotepa and carboplatin and stem cell rescue (HDT). To be eligible, patients had to be free of overt metastatic disease and be < or =60 years of age. Analyses were according to intention to treat. RESULTS At a median follow up of 68 months, 118 patients have experienced a relapse or death from breast cancer (62 in the FEC followed by HDT arm and 56 in the conventional FEC arm) and a total of 100 patients have died (54 in the FEC followed by HDT arm and 46 in the conventional FEC arm). No significant difference was observed in relapse-free survival [hazard ratio 1.06, 95% CI 0.74-1.52, p = 0.76] or overall survival [hazard ratio 1.18, 95% CI 0.80-1.75, p = 0.40]. Five patients died from treatment related causes, three as a consequence of HDT and two in the conventional FEC arm. CONCLUSIONS At the present time, no benefit has been observed from replacing three cycles of conventional chemotherapy with the HDT regimen described here. Patients should continue to receive conventional chemotherapy as adjuvant therapy for breast cancer.

Abstract
OBJECTIVES We developed and established a new dose-finding system, the individualized maximum repeatable dose (iMRD), suitable to induce prolonged TTP rather than tumor shrinkage. METHODS We applied this system in weekly gemcitabine therapy for 18 metastatic pancreas cancer patients. We determined the iMRD at the 5th week, after weekly dose adjustments. We started at 500 mg/m2 (1/2 maximum tolerated dose) of gemcitabine and repeated the treatment with an increase or a decrease of 100 mg/m each week, if toxicity was 0 or more than grade 1, respectively. RESULTS The iMRD of weekly gemcitabine was 300 mg/m2 in 2 patients, 400 mg/m2 in 3 patients, 500 mg/m2 in 5 patients, 600 mg/m2 in 6 patients, and 700 mg/m2 in 2 patients, demonstrating significant differences among individual patients. Grade 3 marrow depression occurred in only 1 patient (5.6%). Of these 18 patients, 3 (16.7%), 13 (72.2%) and 2 (11.1%) patients showed partial response, stable disease, and progressive disease, respectively. The median of times to progressive disease and survival were 4.5 and 9.5 months, respectively. There were no significant differences in 1-year survival time and more than 50% reduction rate of serum CA19-9, a tumor marker for pancreatic cancer, between patients with lower (500 mg/m2 or less) and higher (600 mg/m2 or more) iMRD. CONCLUSION These results suggest that iMRD is a simple method to determine an individual's tailored dose for chemotherapy and could be the optimal dose for patients with noncurable cancers such as metastatic pancreas cancer.

Abstract
Results of adjuvant dose intensification studies in patients with localised breast cancer have raised questions regarding the clinical usefulness of this treatment strategy. Here, we develop and fit a natural history model for the time to clinical tumour recurrence as a function of the number of involved lymph nodes, and derive plausible predictions of the effects of dose intensification under various conditions. The time to tumour recurrence is assumed to depend on the residual postoperative micrometastatic burden of tumour, the fractional reduction of residual tumour burden (RTB) by treatment, and the rate of regrowth of the RTB to a clinically detectable size. It is assumed that a proportion of micrometastatic tumours are unresponsive to adjuvant chemotherapy even at maximal dose intensity. Data fitted included the San Antonio Cancer Institute (SACI) database of untreated patients, and CALGB #9082, a study comparing a highly intensive and moderately intensity adjuvant regimen in patients with 10+ positive axillary nodes. The proportion of tumours unresponsive to maximally intensive adjuvant treatment is estimated to be 48% (29-67%). The estimated log kill for intermediate-dose therapy from CALGB #9082 was 6.5 logs, compared with 9 logs or greater for high-dose therapy. The model is consistent with a modest but nonnegligible advantage of dose intensification compared with standard therapies in patients with sensitive tumours who have 10+ positive axillary nodes, and suggests that much of this clinical benefit could be achieved using intermediate levels of treatment intensification. The model further suggests that, in patients with fewer than 10 involved axillary nodes, any advantage of treatment intensification over standard therapy would be much reduced, because in patients with smaller tumour burdens of sensitive tumour, a larger proportion of cures achievable with intensified therapy could be achieved as well with standard therapy.

Abstract
The purpose of this prospective trial was to study a combined-modality treatment including local consolidation by surgery or radiotherapy and high-dose chemotherapy (HDC) followed by peripheral-blood stem-cell (PBSC) transplantation. In all, 48 patients with oligometastatic breast cancer amenable to local treatment after induction chemotherapy with epirubicin and cyclophosphamide or paclitaxel and cisplatin, depending on prior adjuvant chemotherapy, were enrolled. The median follow-up was 41 months (range, 7-85 months). PBSC were collected in 47 patients, and 40 received one or two courses of HDC. Local therapy was given in 37 patients. No treatment-related deaths occurred. Of 47 evaluable patients, 36 (75% of intention-to-treat population) had no evidence of disease or complete remission after completion of therapy. Six patients (12.5%) had partial response, two patients (4%) no change, and three patients (6%) progressive disease. The median time to progression and overall survival was 17.5 (95% confidence interval (CI), 14-21 months) and 42.2 months (95% CI, 33-52 months), respectively, and 27% of patients were progression free after 5 years. In conclusion, patients with oligometastatic breast cancer can be treated safely with this combined modality protocol with promising relapse-free survivals.

Abstract
Purpose The aims of the present study were (1) to characterize the pharmacokinetics of both component drugs and (2) to describe the relationship between the pharmacokinetics and the dose-limiting hematologic toxicity for the epirubicin (EPI)/docetaxel (DTX) regimen in breast cancer patients. Patients and Methods Forty-four patients with advanced disease received EPI and DTX every 3 weeks for up to nine cycles. The initial doses (EPI/DTX) were 75/70 mg/m2. Based on leukocyte (WBC) and platelet counts, the subsequent doses were, stepwise, either escalated (maximum, 120/100 mg/m2) or reduced (minimum, 40/50 mg/m2). Hematologic toxicity was monitored in all patients, whereas pharmacokinetics was studied in 16 patients. A semiphysiological model, including physiological parameters as well as drug-specific parameters, was used to describe the time course of WBC count following treatment. Results In the final pharmacokinetic model, interoccasion variability was estimated to be less than interindividual variability in the clearances for both drugs. The sum of the individual EPI and DTX areas under concentration-time curve correlated stronger to WBC survival fraction than did the corresponding sum of doses. A pharmacokinetic-pharmacodynamic (PK-PD) model with additive effects of EPI and DTX could adequately describe the data. Conclusion The final PK-PD model might provide a tool for calculation of WBC time course, and hence, for prediction of nadir day and duration of leukopenia in breast cancer patients treated with the EPI/DTX regimen.

Abstract
High-dose chemotherapy is based on the scientific hypothesis that escalating the dose of drug will overcome drug resistance and improve outcome. Autologous bone marrow transplantation and, more recently, peripheral stem cell transplantation used as a means to restore marrow, made this a viable treatment for patients with selected tumours such as haematological malignancies. The role in breast cancer is less certain. Given the known as well as the potential toxicities, the objective of high-dose chemotherapy should be cure as opposed to palliation. However, the natural history of breast cancer can be protracted, with relapses occurring 15-20 years after treatment or within months of curative surgery. In breast cancer there is a positive correlation between recurrence-free and long-term survival. Therefore, the recurrence-free survival can be considered a surrogate endpoint in clinical trials. In patients with metastatic disease where cure is rare, at best, duration of a disease-free state may be a surrogate for overall benefit. Alternatively, time to progression may be another endpoint in the evaluation of treatment for metastatic disease. This is based on the assumption that quality of life is enhanced without progression of disease. Toxicity is the significant issue in the use of high-dose chemotherapy. The most common toxicity is myeloablation, potentially requiring prolonged hospitalisation. The only justification for these toxicities would be evidence of significant and meaningful benefit. A clinically relevant benefit with high-dose chemotherapy has not been seen in major randomised clinical trials of breast cancer in both the adjuvant and metastatic setting. In patients with advanced breast cancer, a small percentage may achieve long-term, disease-free survival, although there is no improvement in overall survival. Nonetheless, some investigators believe that high-dose chemotherapy holds promise, although currently this treatment is not recommended outside of a well designed prospective trial. These studies have provided useful information regarding cancer treatment. However, ongoing study of drug administration intervals, that is, dose-dense therapies, may lead to an approach that allows superior and less toxic treatment for breast cancer.

Abstract
PURPOSE We described previously a prognostic model for high-risk primary breast cancer patients receiving high-dose chemotherapy (HDC). Such model included nodal ratio (no. involved nodes:no. dissected nodes), tumor size, hormone receptors, and HER2. In the present study we intended to test this model prospectively in a second patient cohort. In addition, we analyzed the long-term overall outcome of our HDC trials. EXPERIMENTAL DESIGN We analyzed all 264 patients enrolled since 1990 in our prospective trials for 4-9+, > or = 10+ nodes, or inflammatory disease. Patients of the second cohort (treated since 1997) had their prognostic score estimated prospectively before receiving HDC. RESULTS Fourteen patients (5.3%) died from HDC-related complications. At median follow-up of 7.1 years, relapse-free survival and overall survival of the whole group were 69.8% and 73%, respectively. Median time to relapse was 14 months (63.5% relapses within the first 2 years, 6.7% after year 5). The model was validated in the second cohort, establishing the following pretransplant risk categories: low risk (low score, HER2-), 44% patients, 87% freedom from relapse (FFR); intermediate risk (low score, HER2+), 29% patients, 68% FFR; and high risk (high score, any HER2), 27% patients, 49% FFR. CONCLUSIONS Few relapses are seen after year 5 of follow-up, which indicates the need for mature results of the randomized trials before their final interpretation or meta-analysis. Our prospectively validated prognostic model, if additionally confirmed in the randomized trial populations, may provide an insight into the relative benefit of HDC in different risk patient subsets.

Abstract
Many cytotoxic agents for the adjuvant treatment of breast cancer are available, but they have produced only modest results, even when the tumor burden is low. This relative lack of efficacy may be attributed, in part, to the nonspecificity of the current regimens. Additionally, there is evidence that the chemotherapy doses used in clinical practice are not optimal, which potentially compromises the outcomes when the thresholds of dose intensity are not reached. Variations in treatment underscore the need to return to the basics of chemotherapy administration: dose, schedule, concentration threshold, and therapeutic index. In patients with metastatic breast cancer a clear dose-response curve has been shown with some agents, including anthracyclines. The E-max model, which in its simplest form assumes a direct relation between the dose of a drug and its effect, may be used to improve dosing in the adjuvant treatment of breast cancer. Consistent with this model, threshold effects have been observed in treatment with both anthracyclines and paclitaxel for breast cancer. There is also evidence that using dose-dense schedules may produce better outcomes with some regimens. Maintaining chemotherapy agents at full dose on schedule is crucial to treatment success, especially in adjuvant therapy. Consequently, treatment practices should use both dose intensity and dose compression to increase the likelihood of positive outcomes in patients with breast cancer.

Abstract
For patients whose breast cancers are not responsive to endocrine therapy, there are a large number of cytotoxic drugs that will induce a response. In spite of the introduction of new, very active drugs such as the taxanes, vinorelbine, capecitabine, gemcitabine, and trastuzumab, the anthracyclines are still as active as any--and more active than most--drugs used to treat breast cancer. Their inclusion in combinations to treat early and advanced disease prolongs survival. However, they cause nausea, vomiting, alopecia, myelosuppression, mucositis, and cardiomyopathies. There is no evidence that increasing the dose of conventional anthracyclines or any other of the cytotoxics beyond standard doses will improve outcomes. Schedule may be more important than dose in determining the benefit of cytotoxics used to treat breast cancer. Weekly schedules and continuous infusions of 5-fluorouracil and doxorubicin may have some advantages over more intermittent schedules. Liposomal formations of doxorubicin reduce toxicity, including cardiotoxicity; theoretically they should also be more effective because of better targeting of tumor over normal tissues. Both pegylated liposomal doxorubicin (Doxil/Caelyx [PLD]) and liposomal doxorubicin (Myocet [NPLD]) appeared to be as effective as conventional doxorubicin and much less toxic in multiple phase II and phase III studies. PLD has been evaluated in combinations with cyclophosphamide, the taxanes, vinorelbine, gemcitabine, and trastuzumab, and NPLD has been evaluated in combination with cyclophosphamide and trastuzumab. Both liposomal anthracyclines are less cardiotoxic than conventional doxorubicin. The optimal dose of PLD is lower than that of conventional doxorubicin or NPLD. Patients treated with PLD have almost no alopecia, nausea, or vomiting, but its use is associated with stomatitis and hand-foot syndrome, which can be avoided or minimized with the use of proper dose-schedules. In contrast, the optimal dose-schedule of NPLD is nearly identical to that of conventional doxorubicin. The toxicity profile of NPLD is similar to that of conventional doxorubicin, but toxicities are less severe and NPLD is better tolerated than conventional doxorubicin at higher doses.

Abstract
BACKGROUND To determine the impact of micrometastatic bone marrow cells (MMC) on survival in high-risk primary breast cancer (HRPBC) patients treated with high-dose chemotherapy (HDCT) and autologous stem cell transplantation (ASCT). PATIENTS AND METHODS Ninety-one HRPBC patients (73 patients with > or =10 involved axillary lymph nodes (ALN), 18 premenopausal women with > or =4 involved ALN) received one cycle (eight patients) or two cycles of HDCT and ASCT. Bone marrow aspiration was performed before systemic treatment to search for MMC using a cocktail of four monoclonal epithelial-specific antibodies (5D3, HEA125, BM7 and BM8). The influence of MMC and other prognostic factors on disease-free survival (DFS), distant DFS (DDFS), and overall survival (OS) was analysed. RESULTS In 23 of 91 patients (25%) we detected a median of three MMC (range, 1-43) among 10(6) mononuclear cells. With a median follow-up of 62 months (range, 10-117), the detection of MMC was not associated with DFS (P=0.929), DDFS (P=0.664) or OS (P=0.642). In multivariate analysis the strongest predictor was nodal ratio for DFS (P=0.012) and expression of p53 for OS (P <0.001). CONCLUSION The detection of MMC at diagnosis has no impact on survival in HRPBC patients treated with HDCT and ASCT.

Abstract
PURPOSE To evaluate the safety of concurrent treatment with trastuzumab and high-dose chemotherapy (HDC), using cyclophosphamide, cisplatin, and 1,3-bis(2-chloroethyl)-1-nitrosourea (BCNU), with autologous hematopoietic progenitor cells support, in patients with HER2+ advanced breast cancer. EXPERIMENTAL DESIGN Patients with HER2-overexpressing high-risk primary breast cancer (HRPBC; defined as > or =4 involved nodes or inflammatory disease), or metastatic breast cancer (MBC) were eligible. Treatment consisted of a loading dose of trastuzumab at 4 mg/kg (day -5), HDC (days -5 to -2), autologous hematopoietic progenitor cells infusion on day 0, and weekly maintenance trastuzumab (2 mg/kg) from day +1 (minimum of 9 doses). Cardiac monitoring included serial left ventricular ejection fraction measurements before treatment and on days +20 and +65. RESULTS Thirty-three patients were prospectively enrolled (13 HRPBC, 20 MBC). Toxicity seemed similar to that expected with this HDC regimen alone. Neutrophils and platelets engrafted promptly. There were no cases of grade 4 or 5 toxicity. One patient experienced symptomatic grade 3 acute cardiac failure on day -4, responsive to treatment. Trastuzumab did not alter the pharmacokinetics of HDC. Eleven of twelve MBC patients with measurable disease (nine of them refractory to previous chemotherapy) experienced an objective response (9 complete and 2 partial responses). At median follow-up of 34 (13-58) months, all HRPBC patients remain alive and free of disease; the MBC group has event-free survival and overall survival rates of 45 and 70%, respectively. CONCLUSIONS Incorporation of trastuzumab into HDC (cyclophosphamide, cisplatin, and BCNU) is feasible, with no apparent increased toxicity or pharmacokinetic interactions.

Abstract
We assessed the 5-year results of a high-dose cyclophosphamide, carmustine, and thiotepa (CBT) regimen plus autologous hematopoietic stem cell transplantation (AHST) as an adjuvant consolidation therapy for high-risk primary breast cancer patients with > or =10 positive axillary lymph nodes after primary surgery or > or =4 positive axillary lymph nodes after neoadjuvant chemotherapy and surgery. The associations of various potential prognostic factors with the relapse-free survival (RFS) rate and overall survival (OS) rate were determined. Between October 1992 and March 2000, 177 eligible patients (median age, 46 years) were given high-dose CBT followed by AHST. At a median follow-up of 63 months, the acute treatment-related mortality was 4.5%. Estimated 5-year RFS and OS rates were 62% and 68%, respectively, for all patients. For patients with > or =10 positive axillary lymph nodes after primary surgery, the 5-year RFS and OS rates were 71% and 70%, respectively, and for patients with > or =4 positive axillary lymph nodes after neoadjuvant chemotherapy, the 5-year RFS and OS rates were 53% and 66%, respectively. In 2-sided log-rank tests, earlier disease stage, a lower lymph node ratio, and a lower tumor score were associated with a prolonged RFS and OS. In a multivariate proportional hazards model, disease stage and lymph node ratio remained significant. We concluded that high-dose CBT with AHST for high-risk primary breast cancer is feasible, with comparable efficacy to other phase II studies. More than a 50% estimated 5-year survival rate was seen in all high-risk primary breast cancer patients. In accordance with results from recent randomized studies, we need to continue high-dose chemotherapy with AHST for patients with high-risk primary breast cancer in the phase III randomized setting.

Abstract
Over the past two decades, high-dose chemotherapy (HDC) with autologous stem-cell transplantation (ASCT) has been explored for a variety of solid tumors in adults, particularly breast cancer, ovarian cancer and non-seminomatous germ-cell tumors. The results of prospective phase II studies seemed superior in many cases to the outcome expected with standard-dose chemotherapy (SDC). The value of HDC for adult solid tumors remains, in most instances, a controversial issue, currently under the scrutiny of randomized phase III trial evaluation. ASCT pursuing an immune graft-versus-tumor effect has been evaluated in recent years for patients with advanced and refractory solid malignancies. This article reviews the results of the main phase II and III studies of HDC with ASCT, as well as the preliminary experience using allogeneic transplantation for solid tumors.

Abstract
A randomized phase II clinical trial has been designed and started in the Japanese Foundation for Multidisciplinary Treatment of Cancer (JFMC) to select the better regimen between tailored CPT-11 + S-1 and the standard S-1 treatment for advanced or recurrent gastric cancer as the first line chemotherapy. Selection of the better treatment for general clinical practice in this clinical trial will lead to a more precise assignment of a promising regimen for a future phase III randomized trial, placing continuous 5-FU infusion as the reference arm. In this trial, subsidiary pharmacokinetic analysis for the tailored dose arm is also proposed. In order to continue chemotherapy for a long time and to obtain longer survival, our study design for the tailored therapy could be exploited, especially in the field of general clinical practice.

Abstract
BACKGROUND Hematopoetic stem cell transplants (HSCT) are discussed as treatment options for patients with solid tumors. Transplant numbers have changed substantially over the last decade, few controlled studies are available and different opinions prevail. Objective information on current practice is needed. PATIENTS AND METHODS Data from 27 902 HSCT for solid tumors (2% allogeneic, 98% autologous), collected by the European Group for Blood and Marrow Transplantation (EBMT) activity survey from 1991 to 2002 were used to assess trends, transplant rates and coefficient of variation of transplant rates in Europe. RESULTS Transplant numbers increased from 536 in 1991 to 4154 in 1997 and decreased to 1913 in 2002. Indications were neuroblastoma (2504 HSCT; 9%), glioma (662 HSCT; 2%), soft tissue sarcoma (1253 HSCT; 4%), germ cell cancer (3291 HSCT; 12%), breast cancer (13 524 HSCT; 48%), Ewing's sarcoma (1896 HSCT; 7%), lung cancer (387 HSCT; 1%), ovarian cancer (845 HSCT; 3%) and other solid tumors (3540 HSCT; 14%). Allogeneic cells were used in <20 cases up to 1997; since then allogeneic HSCT increased to 159 in 2002, mainly for renal cell carcinoma. Low coefficients of variation in transplant rates (<60%) are observed for Ewing's sarcoma (<56.5%), suggesting consensus for this indication. CONCLUSIONS These data give an overview on current practice of HSCT for solid tumors in Europe. They provide objective information for health-care providers and patient counselling.

Abstract
BACKGROUND Breast cancer patients with four or more positive axillary lymph nodes who are treated with conventional adjuvant therapy have a poor prognosis. In uncontrolled studies, high-dose chemotherapy produced much better results than conventional therapy. We compared the benefits of a single cycle of high-dose chemotherapy and the benefits of conventional chemotherapy in patients with high-risk breast cancer in a prospective, unblinded, randomized trial. METHODS Between February 23, 1995, and June 29, 1999, 605 patients with breast cancer who had four or more positive lymph nodes were randomly assigned to treatment (307 to high-dose therapy and 298 to conventional therapy). The conventional chemotherapy regimen was four cycles of doxorubicin (75 mg/m2) followed by eight cycles of CMF (cyclophosphamide [600 mg/m2], methotrexate [50 mg/m2], and 5-fluorouracil [600 mg/m2]), all given intravenously on day 1 of a 21-day cycle. The high-dose regimen was four cycles of doxorubicin (75 mg/m2), followed by a single cycle of intermediate-dose cyclophosphamide (4000 mg/m2) supported by filgrastim (300 microg/day) for up to 10 days followed by high-dose cyclophosphamide (6000 mg/m2) and thiotepa (800 mg/m2). Peripheral blood progenitor cells were harvested by leukapheresis after treatment with cyclophosphamide and filgrastim and then re-infused after the high-dose cycle. Log-rank tests were used to compare survival rates. All statistical analyses were two-sided. RESULTS At a median follow-up of 6 years, no statistically significant differences were detected between the arms in 5-year relapse-free survival (high-dose arm = 57%, 95% confidence interval [CI] = 51% to 63%; conventional-dose arm = 54%, 95% CI = 48% to 61% (P =.73) or in 5-year overall survival (high-dose arm = 62%, 95% CI = 56% to 68%; conventional-dose arm = 64%, 95% CI = 57% to 70%) (P =.38). CONCLUSION Autograft-supported, high-dose therapy is not superior to conventional chemotherapy in patients with breast cancer who have multiple involved lymph nodes. This conclusion should be viewed in the context of improving the success of conventional chemotherapy.

Abstract
The overall survival improvement by adjuvant chemotherapy is partly related to patient age, stage and chemotherapy regimens used. Too low dose dose-intensities or total doses will result in inferior outcomes. Conventional dose escalations above standard doses will not be beneficial for doxorubicin or cyclophosphamide, while an epirubicin dose of 90-100mg/m2 given every third week in polychemotherapy regimens results in overall survival gains. The issue is more complex, while retrospective analysis of adjuvant regimens have revealed inferior outcomes for patients receiving standard chemotherapy doses and regimens without toxicity. Most cytostatics demonstrate a marked inter-individual variation in different pharmacokinectic parameters, not compensated for by dosage based on body surface area. These facts have partly been the basis for the randomised Scandinavian Breast Group (SBG) studies SBG 9401 and 2000-1, respectively, using tailored dosage strategies aiming at interpatient equivalent dosage. Randomised studies using marrow supported-high dose strategies have so far not been demonstrated to result in overall survival improvements. G-CSF (granulocyte-colony stimulating factor) and dose-dense paclitaxel containing regimens have resulted in a small but significant survival gain compared with conventional three weekly regimens, challenging the present dogma of conventional three-four weekly scheduling, based on normal tissue side-effects rather than tumour biological considerations. The recent microarray based studies demonstrated marked inter-patient variability in gene expression and underline the potential for better patient selection and more tailored therapy strategies.

Abstract
This final paper of the proceedings of the recent Eighth St. Gallen Conference 2003 on the Primary Therapy of Early Breast Cancer comments on the Consensus Paper put forth by the international expert panel and emphasizes new information, that has emerged during the 2 years since the seventh such meeting in 2001. More than 3200 breast cancer specialists from various medical fields-coming from 75 countries and all six continents-have attended the meeting and the process of scientific consensus development. Recommendations for patient care are so critically dependent on assessment of endocrine responsiveness that the importance of high-quality steroid hormone receptor determination and standardized quantitative reporting cannot be overemphasized. The Panel modified and simplified the risk categories so that only endocrine receptor-absent status was sufficient to reclassify an otherwise low-risk, node-negative disease into the category of average risk. Absence of steroid hormone receptors was also recognized as indicating endocrine non-responsiveness. Some important areas highlighted especially in the 2003 consensus include: recognition of the separate nature of endocrine non-responsive breast cancer, both invasive cancers and ductal carcinoma in situ (DCIS); improved understanding of the mechanisms of acquired endocrine resistance, offering exciting prospects for extending the impact of successful sequential endocrine therapies; presentation of high-quality evidence indicating that chemotherapy and tamoxifen should be used sequentially rather than concurrently; availability of a potential alternative to tamoxifen for treatment of postmenopausal women with endocrine responsive disease; promise of newly defined prognostic and predictive markers.

Abstract
PURPOSE Investigation of high-dose chemotherapy (HD-CT) followed by autologous hematopoietic stem-cell support compared with standard-dose chemotherapy (SD-CT) as adjuvant treatment in patients with primary breast cancer and 10 or more positive axillary lymph nodes. PATIENTS AND METHODS Between November 1993 and September 2000, 307 patients were randomized to receive (following four cycles of epirubicin 90 mg/m(2) and cyclophosphamide 600 mg/m(2), intravenously every 21 days) either HD-CT of cyclophosphamide 1500 mg/m(2), thiotepa 150 mg/m(2), and mitoxantrone 10 mg/m(2), intravenously for 4 consecutive days followed by stem-cell support; or SD-CT in three cycles of cyclophosphamide 500 mg/m(2), methotrexate 40 mg/m(2), and fluorouracil 600 mg/m(2) intravenously on days 1 and 8, every 28 days. The primary end point was event-free survival. RESULTS After a median follow-up of 3.8 years, 144 events with respect to event-free survival have been observed (HD-CT: 63 events; SD-CT: 81 events). The first event of failure (HD-CT v SD-CT) was an isolated locoregional recurrence (nine v 11), a distant failure (52 v 68), and death without recurrence (two v two). The estimated relative risk of HD-CT versus SD-CT was 0.75 (95% CI, 0.54 to 1.06; P =.095). Overall survival showed no difference (HD-CT: 40 deaths; SD-CT: 49 deaths). CONCLUSION There was a trend in favor of HD-CT with respect to event-free survival, but without statistical significance. Further follow-up and a meta-analysis of all randomized studies will reveal the effect of HD-CT as compared with SD-CT as adjuvant treatment in high-risk primary breast cancer.

Abstract
The emerging evidence gained from randomized controlled trials accelerated the widespread use of adjuvant endocrine and cytotoxic regimens and their combinations for most breast cancer patients. Even for the earliest cancer stages with low-risk tumour profiles, endocrine treatment can be recommended as adjuvant therapy if the tumour is endocrine responsive. The 8th consensus conference on early breast cancer in St. Gallen in 2003 opened a plethora of treatment options to nearly all breast cancer patients. Key issues were the introduction of adjuvant therapy with anastrozole for those postmenopausal patients with contra-indications or intolerability of tamoxifen and the definition of a group of 'more potent' regimens like the FEC- and the taxane-based regimens for high-risk patients. Unfortunately the expert panel did not clearly define any recommendations either for choosing optimal candidates for purely endocrine treatments (which are a valid option for all patients with optimal endocrine responsive disease or arguments against chemotherapy) or for the proper high-risk patients scheduled for more aggressive regimens. In the meantime, new or updated studies have provided additional information helpful for the shared decision-making with our patients. The Canadian MA.17 study revealed a significant benefit from adding a sequential therapy with letrozole after 5 years of tamoxifen compared to tamoxifen alone. Together with the updated evaluation from the ATAC trial and the Italian ITA study, the role of adjuvant treatment with aromatase inhibitors is steadily strengthened. Several studies comparing taxane-based and taxane-free regimens showed significant survival and/or recurrence benefits for the former. These data should be communicated to the patients. In the complex process of decision-making, a profound knowledge of the study results and the early and complete involvement of the woman and her personal beliefs are mandatory.

Abstract
PURPOSE OF REVIEW Controversy has surrounded the use of high-dose chemotherapy for breast cancer for more than a decade. Numerous randomized trials have compared high-dose chemotherapy with standard-dose chemotherapy in metastatic breast cancer and high-risk primary breast cancer, defined by extensive axillary node involvement or inflammatory disease. The authors review the main research results of high-dose chemotherapy for breast cancer in 2002 to 2003. RECENT FINDINGS Preliminary analyses of three randomized trials in metastatic breast cancer and seven in high-risk primary breast cancer have been reported during this period. An advantage in event-free survival has been observed in all three studies in metastatic disease and in four of the high-risk primary cancer trials, albeit with no impact on overall survival at short follow-up. These early results are consistent with the most recent Cochrane reviews, which included trials reported through mid 2002. SUMMARY An early event-free survival advantage is apparent in favor of high-dose chemotherapy in both high-risk primary and metastatic breast cancer. Longer follow-up of those and most other trials is required to detect translation of the event-free survival differences into benefits in overall survival. High-dose chemotherapy remains a valid research strategy in event-free survival and high-risk primary breast cancer.

Abstract
Despite the extensive literature clearly demonstrating the survival benefit for adjuvant chemotherapy in women with operable breast cancer, there are few data confirming this in routine practice. Some studies have suggested that not all women gain to the same extent, with older women showing a smaller benefit and lower doses achieving poorer outcomes. We therefore reviewed the case notes of 750 women treated over a 15-year period at The Edinburgh Cancer Centre with the same intravenous CMF (cyclophosphamide, methotrexate and 5-fluorouracil) regimen, to identify patient- and treatment-related factors influencing outcome in routine practice.The actuarial 10-year survival for these women was 59.3%, with the anticipated poorer outcome for those with more involved ipsilateral axillary nodes, higher grade and ER-negative tumours. There was no evidence that a lower delivered dose intensity or older age at presentation resulted in a poorer survival. Of particular interest was the observation that 45% of patients who had grade 2/3 neutropenia had a 10% absolute survival advantage over those with no neutropenia (P<0.001). This strongly suggests that some degree of neutropenia has more influence on outcome than age or delivered dose intensity.

Abstract
Immunoparalysis, characterised by impairments in neutrophil and monocyte/macrophage function, is common in critically ill patients. The theoretical ability of granulocyte colony-stimulating factor (G-CSF) to improve the functions of both neutrophils and monocytes/macrophages provides a rationale for G-CSF therapy in non-neutropenic critically ill patients with infection or a high risk of nosocomial infection. The expression of the receptors that mediate G-CSF effects in neutrophils and monocytes/macrophages is regulated by bacterial products, cytokines and endogenous G-CSF levels, accounting for the variables effects of G-CSF on the neutrophil functions of critically ill patients. This variability should be taken into account when designing studies on the use of G-CSF in ICU-patients. Studies are still needed to identify the subset of patients who may benefit from G-CSF therapy.

Abstract
Comparative clinical trials are performed to assess whether a new treatment has superior efficacy than a placebo or a standard treatment (one-sided formulation) or whether two active treatments have different efficacies (two-sided formulation) in a given population. The reference approach is the single-stage design and the statistical test is performed after inclusion and evaluation of a predetermined sample size. In practice, the single-stage design is sometimes difficult to implement because of ethical concerns and/or economic reasons. Thus, specific early termination procedures have been developed to allow repeated statistical analyses to be performed on accumulating data and stop the trial as soon as the information is sufficient to conclude. Two main different approaches can be used. The first one is derived from strictly sequential methods and includes the sequential probability ratio test and the triangular test. The second one is derived from group sequential designs and includes Peto, Pocock, and O'Brien and Fleming methods, alpha and beta spending functions, and one-parameter boundaries. We review all these methods and describe the bases on which they rely as well as their statistical properties. We also compare these methods and comment on their advantages and drawbacks. We present software packages which are available for the planning, monitoring and analysis of comparative clinical trials with these methods and discuss the practical problems encountered when using them. The latest versions of all these methods can offer substantial sample size reductions when compared with the single-stage design not only in the case of clear efficacy but also in the case of complete lack of efficacy of the new treatment. The software packages make their use quite simple. However, it has to be stressed that using these methods requires efficient logistics with real-time data monitoring and, apart from survival studies or long-term clinical trials with censored endpoints, is most appropriate when the endpoint is obtained quickly when compared with the recruitment rate.

Abstract
Purpose: To compare, in high-risk breast cancer patients, the effects on health-related quality of life (HRQoL) of two adjuvant treatments. Treatments were compared at eight points during the first year after random assignment to treatment with tailored fluorouracil, epirubicin, and cyclophosphamide (FEC) therapy for nine courses versus induction FEC therapy for three courses followed by high-dose chemotherapy with cyclophosphamide, thiotepa, and carboplatin (CTCb) supported by peripheral-blood stem cells. Patients and Methods: From March 1994 to March 1998, 525 breast cancer patients (estimated relapse risk > 70% within 5 years with standard therapy) were included in the Scandinavian Breast Group 9401 study. HRQoL evaluation, using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ)-C30 and EORTC Breast Cancer Module–23, included 408 of 446 eligible patients in Finland, Norway, and Sweden. Results: Eighty-four percent to 95% of the patients completed questionnaires at eight points of assessment. Nostatistically significant overall differences were found between the tailored FEC group and the CTCb group for any of the HRQoL variables. Statistically significant differences over time were found for all HRQoL variables. HRQoL in the CTCb group demonstrated a steeper decrease, but a faster recovery than in the tailored FEC group. Emotional functioning improved with increased time from randomization. Higher levels of problems in body image and arm symptoms were reported in the tailored FEC group compared with the CTCb group. Sexual functioning and satisfaction were impaired during the study period. Conclusion: Both treatments had a negative influence on HRQoL during the treatment period. Despite the aggressive therapies, the patient’s HRQoL returned to levels found at inclusion on most variables.

Abstract
The aim of this study was to identify trends in high-dose chemotherapy (HDC) with autologous hematopoietic stem cell transplantation (ASCT) and to assess survival in a large cohort of breast cancer (BC) patients receiving this therapy in Europe from 1990 to 1999. A total of 7471 patients who received HDC with ASCT between January 1, 1990 and December 31, 1999 were reported to the European Group for Blood and Marrow Transplantation Registry. Data required for demographics and survival analysis were available for 2679 patients with high-risk primary BC; 921 patients with inflammatory BC (IBC), and 2295 patients with metastatic disease. The main evaluation parameters were progression-free survival (PFS) and overall survival (OS). Between 1990 and 1998, autotransplants for BC increased 30-fold. Significant trends included use of blood-derived rather than marrow-derived stem cells, increment of reporting centers and decrease of mortality within 100 days from transplantation. The 5-year PFS and OS probabilities were 53 and 68% for high-risk disease and 42 and 53% for IBC, respectively. For metastatic disease 5-year PFS and OS probabilities in the whole cohort were 18 and 27%, respectively, while for women transplanted in complete remission the 5-year PFS was 29%. In conclusion, HDC with ASCT has been increasingly used until 1998 and the 100-day mortality rate has been constantly less than 2% from 1995 to date. The 5-year survival of high-risk BC is related to the number of axillary nodes involved at surgery. Outcome of patients with IBC is encouraging, suggesting the need for randomized trials. Patients with metastatic disease responding to pretransplant chemotherapy and harboring ER+ tumors have a better outcome.

Abstract
This account of the highlights of the eighth St Gallen (Switzerland) meeting in 2003 emphasizes new information that has emerged during the 2 years since the seventh meeting in 2001. This article should be read in conjunction with the report of that earlier meeting. Recommendations for patient care are so critically dependent on assessment of endocrine responsiveness that the importance of high-quality steroid hormone receptor determination and standardized quantitative reporting cannot be overemphasized. The International Consensus Panel modified the risk categories so that only endocrine receptor-absent status was sufficient to reclassify an otherwise low-risk, node-negative disease into the category of average risk. Absence of steroid hormone receptors also was recognized as indicating endocrine nonresponsiveness. Some important areas highlighted at the recent meeting include: (1) recognition of the separate nature of endocrine-nonresponsive breast cancer-both invasive cancers and ductal carcinoma-in-situ; (2) improved understanding of the mechanisms of acquired endocrine resistance, which offer exciting prospects for extending the impact of successful sequential endocrine therapies; (3) presentation of high-quality evidence indicating that chemotherapy and tamoxifen should be used sequentially rather than concurrently; (4) availability of a potential alternative to tamoxifen for treatment of postmenopausal women with endocrine-responsive disease; and (5) the promise of newly defined prognostic and predictive markers.

Abstract
PURPOSE Cyclophosphamide, epirubicin, and fluorouracil (CEF), compared with classical cyclophosphamide, methotrexate, and fluorouracil (CMF) chemotherapy. has lead to an improvement in relapse-free and overall survival in premenopausal women with node-positive breast cancer. We undertook this analysis to more accurately define the estimate of risk of secondary acute leukemia (sAL) following epirubicin-containing chemotherapy regimens. PATIENTS AND METHODS We assessed the conditional probability of sAL among 1,545 women who received adjuvant (n = 1,477) or neoadjuvant (n = 68) chemotherapy in four National Cancer Institute of Canada Clinical Trials Group trials from 1990 to 1999. The risks associated with epirubicin-containing regimens (CEF or epirubicin and cyclophosphamide [EC]) and other regimens (doxorubicin and cyclophosphamide [AC] or CMF) were determined. RESULTS A total of 10 cases of sAL were observed (eight acute myelogeneous leukemia, two acute lymphoblastic leukemia): seven among women treated with CEF, two who had received AC, and one following CMF. Using competing risk statistics, the conditional probability of sAL was 1.7% (95% confidence interval [CI], 0.5 to 3.6) among 539 women treated with CEF chemotherapy at a follow-up of 8 years, 0.4% (95% CI, 0% to 1.3%) among the 678 who received CMF, and 1.3% (95% CI, 0% to 4.7%) among the 231 treated with AC. The conditional probability of death from breast cancer at 8 years for the entire group of women treated with epirubicin-containing regimens in all four trials was approximately 34.9%. CONCLUSION CEF chemotherapy for breast cancer carries a small increased risk of sAL compared with CMF. These estimates of acute leukemia risk are important in discussing treatment with women, especially patients with a lower risk of death from breast cancer, such as those with node-negative breast cancer.

Abstract
Metastatic breast cancer has been a common indication for autologous hematopoietic stem cell transplantation (HSCT). Previous reports indicate 3-year survival and progression-free survival (PFS) rates after autotransplant to be about 30 and 15%, respectively. Most deaths are from recurrent disease. One potential cause for high relapse rates is graft contamination with tumor. We describe 14 women with metastatic breast cancer transplanted between 1991 and 1998 with hematopoietic cells from identical twins. Median age was 41 y (range 34-50). Most women (12 of 14) were treated with mastectomy, and all received anthracycline-based regimens in their pretransplant course; nine women also received a taxane, seven radiotherapy and three hormonal therapy. Four women were in complete remission (one CR, three CRU) at transplant, five were in partial remission, two had stable disease and two had progressive disease. Eight women have died, one of treatment-related causes and seven of progressive breast cancer. Three-year survival was 48% (21-71%) and 3-year PFS was 21% (5-45%). Although the number of patients is small, outcomes for women transplanted with syngeneic grafts are similar to those of women receiving autologous grafts. This suggests that residual cancer in the patient is the major contributor to relapse after transplantation for breast cancer.

Abstract
High-dose chemotherapy (HD-CT) has a role in the potentially curative treatment of several tumours. The relative efficacies of the different regimens have not been studied in comparative trials, but it is clear that toxicities differ significantly between them. We analysed the immediate and long-term toxicity in the first 100 consecutive patients treated with the CTC regimen (cyclophosphamide 6000 mg m(-2), carboplatin 1600 mg m(-2) (or 20 mg ml(-1) min under the curve (AUC)) both as daily 1 h infusion, thiotepa 480 mg m(-2) as twice daily 30 min infusion, all divided over 4 consecutive days) followed by peripheral blood progenitor cell reinfusion (PBPC-Tx). Most patients had high-risk (n=86) or metastatic (n=4) breast cancer, or a germ cell tumour (n=8). Two patients (with a medulloblastoma and an aesthesioneuroblastoma, respectively) received CTC as off-protocol salvage regimen. The main toxicity was bone marrow suppression. Most patients had PBPC-Tx with granulocyte colony-stimulating factor (G-CSF), and the median time to neutrophil count 500 x 10(6) l(-1) and platelet count >20 x 10(9) l(-1) without transfusion independence was 10 (range 8-25) and 13 (8-60) days, respectively. The toxic death rate was 1%. Other frequent toxicities were neutropenic fever requiring antibiotics (n=65), central catheter-related infection (n=12) or a bleeding episode (n=48), mostly epistaxis (n=26). Reversible cardiac toxicity was seen in six patients and pulmonary events occurred in seven patients (infection (n=6), embolism (n=1)). Grade 3-4 gastrointestinal toxicity was frequent: nausea and vomiting 55%, diarrhoea 28% and mild liver toxicity (transaminase elevations) 9%. One patient pretreated with cisplatin had a kidney transplantation 8 years after HD-CT. Late complications included reversible radiation pneumonitis (n=12) and chronic heart failure (n=2). We found five second solid malignancies and two myelodysplasias. In conclusion, the CTC regimen is associated with a moderate, mainly reversible, toxicity. Future studies need to compare the efficacy and toxicity of the different HD-CT regimens.

Abstract
We retrospectively analyzed the outcome of 67 patients with breast (n=24), ovarian (n=11) or testicular cancer (n=32) treated for relapse after high-dose chemotherapy (HDC) and peripheral blood stem cell (PBSC) transplantation. Treatment, survival and toxicity were analyzed. Patients with breast, ovarian or testicular cancer received a mean of 5.9 (range 1-24), 5.1 (1-13) and 4.6 (1-13) regimens for relapse after HDC. Overall response at the end of the observation period was 20.8% for patients with breast cancer (three complete (CR) and two partial responses (PR)), 45.5% (one CR, four PR) for ovarian and 9.4% (three PR) for testicular cancer patients. The mean overall-survival (OAS) from first relapse was 28 (range 3-44), 17 (2-24) and 10 (1-28) months, respectively. Leukocytopenia grade 3/4 occurred in 27-63% of patients, and thrombocytopenia grade 3/4 was observed in 58-88%, respectively. Nonhematological grade 3/4 toxicities were below 20%. In conclusion, patients with relapse after HDC usually have a poor outcome but long-term survivors are observed. Hematological toxicity is common, while other severe side effects are less frequent.

Abstract
PURPOSE Response assessment at neoadjuvant (preoperative) chemotherapy of locally advanced breast cancer using clinical examination and mammography is insensitive. Mammoscintigraphy with 99mTc-MIBI was studied for the prediction of response at such therapy before finishing the chemotherapy cycles. MATERIAL AND METHODS Chemotherapy was given as repeated courses of 5-fluorouracil, epirubicin and cyclophosphamide (FEC). In 1 patient group (n = 23), the tumor uptake relative to surrounding breast tissue and lung tissue at SPECT examination after finishing neoadjuvant chemotherapy was compared with the examination made before chemotherapy. In another group (n = 30), a similar comparison after the first therapy cycle (mean 19 days) with a baseline examination was made. Histologic examination of the resected tumors was made. RESULTS After finishing chemotherapy, there was a strong reduction of the relative tumor activity, while there was no correlation with therapy effect as assessed by histology. After one therapy course, there was no significant reduction of the relative tumor uptake. CONCLUSION Scintigraphy with 99mTc-MIBI demonstrated the response after finished neoadjuvant chemotherapy of breast cancer using FEC-courses. It cannot be used to predict a therapy response after one therapy course.

Abstract
BACKGROUND To determine the incidence of secondary myelodysplasia (sMDS) or acute myeloid leukemia (AML) in node-positive breast cancer patients who received high-dose chemotherapy (HDCT) followed by autologous stem-cell support as adjuvant therapy. PATIENTS AND METHODS The incidence of sMDS/AML was retrospectively assessed in 364 node-positive breast cancer patients who received HDCT followed by autologous stem-cell support as adjuvant therapy between November 1989 and December 1997 and were reported to the European Group for Blood and Marrow Transplantation registry. RESULTS The median age of the patients was 45 years (range 22-62 years). Two hundred and ninety-one patients received peripheral blood stem cells and 55 patients received autologous bone marrow as stem-cell support. The most frequently used conditioning regimen was the STAMP-V regimen (32%), followed by melphalan-thiotepa (22%) and melphalan-mitoxantrone-cyclophosphamide (21%). The 5-year probability of overall survival is 71% (95% CI 65% to 77%). After a median follow-up of 48 months (range 1-108 months) only one case of AML was observed, resulting in a crude incidence of 0.27%. This case of AML was observed 18 months after HDCT consisting of three cycles of epirubicin and cyclophosphamide with a cumulative dose of epirubicin 960 mg and cyclophosphamide 19 g. The French-American-British type of AML was M4, and the cytogenetic analysis showed a translocation t(9;11)(p22;q23). After complete remission following high-dose cytarabine and idarubicin the patient relapsed and died. CONCLUSIONS In contrast to patients with malignant lymphoma there seems to be no increased risk of sMDS/AML after HDCT in breast cancer. Continued monitoring is required to confirm this low incidence after a longer follow-up period.

Abstract
PURPOSE This study was designed to determine whether increasing the dose of doxorubicin in or adding paclitaxel to a standard adjuvant chemotherapy regimen for breast cancer patients would prolong time to recurrence and survival. PATIENTS AND METHODS After surgical treatment, 3,121 women with operable breast cancer and involved lymph nodes were randomly assigned to receive a combination of cyclophosphamide (C), 600 mg/m(2), with one of three doses of doxorubicin (A), 60, 75, or 90 mg/m(2), for four cycles followed by either no further therapy or four cycles of paclitaxel at 175 mg/m(2). Tamoxifen was given to 94% of patients with hormone receptor-positive tumors. RESULTS There was no evidence of a doxorubicin dose effect. At 5 years, disease-free survival was 69%, 66%, and 67% for patients randomly assigned to 60, 75, and 90 mg/m(2), respectively. The hazard reductions from adding paclitaxel to CA were 17% for recurrence (adjusted Wald chi(2) P =.0023; unadjusted Wilcoxon P =.0011) and 18% for death (adjusted P =.0064; unadjusted P =.0098). At 5 years, the disease-free survival (+/- SE) was 65% (+/- 1) and 70% (+/- 1), and overall survival was 77% (+/- 1) and 80% (+/- 1) after CA alone or CA plus paclitaxel, respectively. The effects of adding paclitaxel were not significantly different in subsets defined by the protocol, but in an unplanned subset analysis, the hazard ratio of CA plus paclitaxel versus CA alone was 0.72 (95% confidence interval, 0.59 to 0.86) for those with estrogen receptor-negative tumors and only 0.91 (95% confidence interval, 0.78 to 1.07) for patients with estrogen receptor-positive tumors, almost all of whom received adjuvant tamoxifen. The additional toxicity from adding four cycles of paclitaxel was generally modest. CONCLUSION The addition of four cycles of paclitaxel after the completion of a standard course of CA improves the disease-free and overall survival of patients with early breast cancer.

Abstract
The aims of this study were to describe how a group of patients with different malignant diseases perceived symptom distress (SD), functional status (FS) and health-related quality of life (HRQOL) on admission to the hospital for stem-cell transplantation (SCT), to compare the obtained data regarding FS and HRQOL with similar data from two general-population groups, and to relate the results to disease- and treatment-specific data. Fifty-one patients participated in the study. Three instruments were used to collect data: SFID-SCT, SIP and SWED-QUAL. The majority of the patients (92%) reported ongoing symptoms even before the SCT with tiredness (67%) and anxiety (53%) as the two most commonly reported symptoms. Although tiredness and anxiety were reported to be the most frequently occurring symptoms, these symptoms were not considered to cause that much distress. Instead, vomiting, reduced mobility and fever, although less commonly occurring, were reported as highly distressing when present. Compared with the general-population groups, the patients reported significantly poorer FS and HRQOL but no statistically significant correlations were found between SD, FS or HRQOL and the time since the last chemotherapy cycle or cycles respectively. Patients with advanced disease and patients with multiple myeloma were found to report more SD and poorer FS and HRQOL.

Abstract
Drug resistance is the main cause of therapeutic failure and death in patients with cancer. However, there have been surprisingly few studies designed specifically to investigate the mechanisms underlying poor treatment response in vivo, compared with the number of phase II and III trials investigating treatment effects. We can now analyse the expression patterns of multiple genes by use of microarrays, rapid gene sequencing, and proteomics, and so need to reassess the way we design clinical trials to take full advantage of these new opportunities. I discuss the concept of clinical studies of chemoresistance in terms of the collection of tumour samples for biological studies, the use of appropriate clinical settings, and the importance of trial design. Ideally, such studies should investigate specific biological features in relation to measurable antitumour effects of single drugs.

Abstract
Preliminary randomized studies have failed to show a survival benefit of high-dose chemotherapy with alkylators in advanced breast cancer. Idarubicin is an active agent in breast cancer and is suitable for dose escalation. We designed a dose finding study with escalating high-dose idarubicin (HD-Ida) followed by fixed high-dose thiotepa+melphalan (HD-TM) with peripheral blood progenitor cells (PBPC) in MBC patients with stable disease or in partial response after six courses of induction chemotherapy with gemcitabine 1000 mg/m(2) days 1 and 4, epirubicin 90 mg/m(2) day 1, taxol 175 mg/m(2) day 1 (GET). Aims of the study were to identify the maximum tolerated dose (MTD) of idarubicin, to evaluate the cardiac safety and activity of HD-Ida and HD-TM after GET and to study the pharmacokinetic profile of idarubicin and idarubicinol. A total of 14 patients were treated. Idarubicin was administered as a 48 h continuous i.v. infusion at the following dose levels: 40 mg/m(2) (three patients), 50 mg/m(2) (three patients), 60 mg/m(2) (five patients) and 70 mg/m(2) (three patients). Mucositis was the dose-limiting toxicity and the MTD was 60 mg/m(2). C(max) of Idarubicin and idarubicinol were 7.7+/-2.0 and 26.3+/-9.7 ng/ml at 40 mg/m(2) and increased to 14.8+3.0 and 47.4+12.6 ng/ml at 70 mg/m(2). AUCt(0-264) of idarubicin and idarubicinol increased from 423.2+/-111.6 and 2581+/-606 hng/ml at 40 mg/m(2) to 732.8+/-140.2 and 4590+/-1258 hng/ml at 70 mg/m(2). Conversion rates after HD-Ida and HD-TM were 28.6 and 38.5%, respectively. No episodes of cardiac toxicity were observed. We conclude that HD-Ida followed by HD-TM is feasible and devoid of cardiac toxicity. Moreover, the activity of HD-Ida after a epirubicin-containing regimen suggests incomplete cross-resistance between the two drugs.

Abstract
BACKGROUND Early studies of high-dose chemotherapy (HDC) for breast cancer were limited by small numbers and the lack of adequate control groups. The French PEGASE Group was founded to perform larger and properly randomized comparative studies of this approach. METHODS The program was created to determine the effects of intensive chemotherapy for breast cancer. The seven PEGASE protocols addressed HDC as adjuvant therapy (01 and 06) and as treatment for inflammatory nonmetastatic disease (02, 05, and 07) and metastatic disease (03 and 04). Two of these protocols are ongoing. RESULTS The PEGASE 01 adjuvant therapy trial showed that 3-year disease-free survival was significantly better in the HDC arm but overall survival was unchanged. The ongoing phase III 06 trial is studying a higher dosage regimen. The HDC trials for metastatic and inflammatory nonmetastatic disease are encouraging. CONCLUSIONS Many clinicians no longer subscribe to the concept of HDC for breast cancer. Overall outcomes from management of poor-risk breast cancer remain poor, however, and it is possible that some selected subgroups of patients may benefit from such an approach.

Abstract
BACKGROUND Overall survival rates are disappointing for women with early poor prognosis breast cancer. There is a hypothesis that high dose chemotherapy with autologous bone marrow or stem cell transplant (autograft) may improve survival rates by permitting higher doses of adjuvant chemotherapy to be given. OBJECTIVES To compare the effectiveness of high dose chemotherapy and autograft versus conventional chemotherapy for women with early poor prognosis breast cancer. SEARCH STRATEGY We searched the Cochrane Breast Cancer Group specialised register, The Cochrane Controlled Trials Register (Cochrane Library Issue 3, 2002), MEDLINE (1966 to Aug. 2002), EMBASE (1980 to Aug. 2002), PsycINFO (1984 to Aug. 2002), Cinahl (1982 to July 2002), the websites of co-operative research groups and ASCO (American Society of Clinical Oncologists) and reference lists of articles found. SELECTION CRITERIA Randomised controlled trials comparing the effectiveness of high dose chemotherapy and autograft versus conventional chemotherapy for women with early poor prognosis breast cancer. DATA COLLECTION AND ANALYSIS We identified nine trials that met the inclusion criteria. Three independent reviewers extracted data. MAIN RESULTS In total 1758 women were randomised to receive high dose chemotherapy with autograft and 1767 women were randomised to receive conventional chemotherapy. There were 48 non cancer-related deaths on the high dose arm and four on the conventional dose arm (RR 7.74, 95% CI (3.43, 17.50). Since many studies have not completed follow-up, overall survival rates were in most cases based on results to date. There was no statistically significant difference in overall survival between women who received high dose chemotherapy with autograft and women who received conventional chemotherapy, either at three years (RR 1.02, 95% CI (0.98, 1.06)), or at five years (RR 0.98, 95% CI (0.93, 1.05)). There was a statistically significant benefit in event-free survival at three years for the group who received high dose chemotherapy (RR 1.11, 95% CI (1.05, 1.18)). However at five years there was no statistically significant difference between the groups (RR 1.00, 95% CI (0.92, 1.08)). Side-effects were more common and more severe in the high dose group though most were reversible. Women in the high dose group reported significantly worse quality of life scores immediately after treatment but at one year there was no statistically significant difference between the groups in quality of life scores. REVIEWER'S CONCLUSIONS There is insufficient evidence to support the routine use of high dose chemotherapy with autograft for women with early poor prognosis breast cancer.

Block sequential adriamycin CMF--optimal non-myeloablative chemotherapy for high risk adjuvant breast cancer? Br J Cancer 2002; 87:1365-9.

Abstract
After the publication of the 10-year survival data from Milan on the adjuvant use of the block sequential regimen consisting of four cycles of adriamycin followed by eight cycles of intravenous CMF, many centres adopted this as standard of care for high risk, multiple node-positive breast cancer. For this reason it was identified as the standard arm for the Anglo-Celtic adjuvant high-dose chemotherapy trial. This study reports on the experience of this regimen in 329 women with early breast cancer involving at least four axillary nodes, who were treated outside any adjuvant chemotherapy trial. At a median follow-up of 3 years, the overall 5-year disease-free survival is 61%, and the overall survival is 70%. These data confirm the efficacy of this regimen in non-trial patients, and, for the same high risk subgroup, indicate that this approach offers an outcome at least as good as that seen in the CALGB 9344 AC-Taxol arm, and the NCIC days 1 and 8 CEF.

Administration of low-dose interleukin-2 plus G-CSF/EPO early after autologous PBSC transplantation: effects on immune recovery and NK activity in a prospective study in women with breast and ovarian cancer. Bone Marrow Transplant 2002; 30:571-8.

Abstract
This study evaluated the effects of low-dose IL-2 plus G-CSF/EPO on post-PBSC transplantation (PBSCT) immune-hematopoietic reconstitution and NK activity in patients with breast (BrCa) and ovarian cancer (OvCa). To this end, two consecutive series of patients were prospectively assigned to distinct post-PBSCT cytokine regimens (from day +1 to day +12) which consisted of G-CSF (5 microg/kg/day) plus EPO (150 IU/kg/every other day) in 17 patients (13 BrCa and 4 OvCa) or G-CSF/EPO plus IL-2 (2 x 10(5) IU/m(2)/day) in 15 patients (10 BrCa and 5 OvCa). Hematopoietic recovery and post-transplantation clinical courses were comparable in G-CSF/EPO- and in G-CSF/EPO plus IL-2-treated patients, without significant side-effects attributable to IL-2 administration. In the early and late post-transplant period a significantly higher PMN count was observed in G-CSF/EPO plus IL-2-treated patients (P = 0.034 and P = 0.040 on day +20 and +100, respectively). No significant differences were found between the two groups of patients in the kinetics of most lymphocyte subsets except naive CD45RA(+) T cells which had a delayed recovery in G-CSF/EPO plus IL-2 patients (P = 0.021 on day +100). No significant difference was observed between NK activity in the two different groups, albeit a significantly higher NK count was observed in G-CSF/EPO plus IL-2 series on day +20 (P = 0.020). These results demonstrate that low-dose IL-2 can be safely administered in combination with G-CSF/EPO early after PBSCT and that it exerts favorable effects on post-PBSCT myeloid reconstitution, but not on immune recovery.
