PURPOSE This randomized, multicenter trial compared first-line trastuzumab plus docetaxel versus docetaxel alone in patients with human epidermal growth factor receptor 2 (HER2) -positive metastatic breast cancer (MBC). PATIENTS AND METHODS Patients were randomly assigned to six cycles of docetaxel 100 mg/m2 every 3 weeks, with or without trastuzumab 4 mg/kg loading dose followed by 2 mg/kg weekly until disease progression. RESULTS A total of 186 patients received at least one dose of the study drug. Trastuzumab plus docetaxel was significantly superior to docetaxel alone in terms of overall response rate (61% v 34%; P = .0002), overall survival (median, 31.2 v 22.7 months; P = .0325), time to disease progression (median, 11.7 v 6.1 months; P = .0001), time to treatment failure (median, 9.8 v 5.3 months; P = .0001), and duration of response (median, 11.7 v 5.7 months; P = .009). There was little difference in the number and severity of adverse events between the arms. Grade 3 to 4 neutropenia was seen more commonly with the combination (32%) than with docetaxel alone (22%), and there was a slightly higher incidence of febrile neutropenia in the combination arm (23% v 17%). One patient in the combination arm experienced symptomatic heart failure (1%). Another patient experienced symptomatic heart failure 5 months after discontinuation of trastuzumab because of disease progression, while being treated with an investigational anthracycline for 4 months. CONCLUSION Trastuzumab combined with docetaxel is superior to docetaxel alone as first-line treatment of patients with HER2-positive MBC in terms of overall survival, response rate, response duration, time to progression, and time to treatment failure, with little additional toxicity.

PURPOSE To compare the efficacy and tolerability of tamoxifen with that of letrozole, an oral aromatase inhibitor, with tamoxifen as first-line therapy in postmenopausal women with advanced breast cancer. PATIENTS AND METHODS Nine hundred seven patients were randomly assigned letrozole 2.5 mg once daily (453 patients) or tamoxifen 20 mg once daily (454 patients). Patients had estrogen receptor- and/or progesterone receptor-positive tumors, or both receptors were unknown. Recurrence during adjuvant antiestrogen therapy or within the following 12 months or prior endocrine therapy for advanced disease precluded enrollment. One prior chemotherapy regimen for metastatic disease was allowed. The primary end point was time to progression (TTP). Secondary end points included overall objective response rate (ORR), its duration, rate and duration of clinical benefit, time to treatment failure (TTF), overall survival, and tolerability. RESULTS TTP was significantly longer for letrozole than for tamoxifen (median, 41 v 26 weeks). Treatment with letrozole reduced the risk of progression by 30% (hazards ratio, 0.70; 95% confidence interval, 0.60 to 0.82, P =.0001). TTP was significantly longer for letrozole irrespective of dominant site of disease, receptor status, or prior adjuvant antiestrogen therapy. Similarly, TTF was significantly longer for letrozole (median, 40 v 25 weeks). ORR was higher for letrozole (30% v 20%; P =.0006), as was the rate of clinical benefit (49% v 38%; P =.001). Survival data are currently immature and not reported here. Both treatments were well tolerated. CONCLUSION Letrozole was significantly superior to tamoxifen in TTP, TTF, ORR, and clinical benefit rate. Our results support its use as first-line endocrine therapy in postmenopausal women with advanced breast cancer.

Since chemotherapy for metastatic breast cancer is not curative, consideration of the quality of life is important in selecting a treatment regimen. We conducted a randomized trial comparing continuous chemotherapy, administered until disease progression was evident, with intermittent therapy, whereby treatment was stopped after three cycles and then repeated for three more cycles only when there was evidence of disease progression. Each approach was tested with doxorubicin combined with cyclophosphamide or with cyclophosphamide combined with methotrexate, fluorouracil, and prednisone. Intermittent therapy resulted in a significantly worse response (P = 0.02 by Mann-Whitney test), a significantly shorter time to disease progression (relative risk based on proportional-hazards model, 1.8; 95 percent confidence interval, 1.4 to 2.4), and a trend toward shorter survival (relative risk, 1.3; confidence interval, 0.99 to 1.6). The quality of life was expressed as linear-analogue self-assessment scores for physical well-being, mood, pain, and appetite and as a quality-of-life index. It improved significantly during the first three cycles, when all patients received treatment. Thereafter, intermittent therapy was associated with worse scores for physical well-being (by 23 percent of scale; 95 percent confidence interval, 11 to 35 percent), mood (25 percent; 13 to 37 percent), and appetite (12 percent; 0 to 24 percent) and for the quality-of-life index as indicated by the patient (14 percent; 5 to 23 percent) and the physician (16 percent; 7 to 26 percent). Changes in the quality of life were independent prognostic factors in proportional-hazards models of subsequent survival. We conclude that, as tested, continuous chemotherapy is better than intermittent chemotherapy for advanced breast cancer.

PURPOSE To determine how patients with infiltrating lobular carcinoma (ILC) differ from patients with the more common infiltrating ductal carcinoma (IDC) with regard to patient and tumor factors, local treatment, and patterns of recurrence. PATIENTS AND METHODS Twelve thousand two hundred six breast cancer patients entered onto 15 International Breast Cancer Study Group trials between 1978 and 2002 were categorized as having ILC, IDC, or other/mixed types. RESULTS Seven hundred sixty-seven tumors (6.2%) were classified as ILC, 8,607 (70.5%) were classified as IDC, and 2,832 (23.2%) were classified as other. The analysis is limited to the 9,374 patients categorized as either pure IDC or ILC. The median follow-up time was 13 years. Compared with IDC, ILC was associated with older age; larger, better differentiated, and estrogen receptor (ER)-positive tumors; and less vessel invasion. Mastectomy was used more frequently for ILC (P < .01). There was a significant (P < .01) early advantage in disease-free survival and overall survival for the ILC cohort followed by a significant (P < .01) late advantage for the IDC cohort after 6 and 10 years, respectively. Similar patterns were observed in cohorts defined by ER status. ILC was associated with an increased incidence of bone events but a decrease in regional and lung events (all P < .01). CONCLUSION ILC is more than a histologic variant of breast cancer. The diagnosis of ILC carries distinct prognostic and biologic implications.

PURPOSE To retrospectively evaluate the pattern of recurrence and outcome of node-negative breast cancer (BC) according to major subtypes. PATIENTS AND METHODS In all, 1,951 patients with node-negative, early-stage BC randomly assigned in International Breast Cancer Study Group Trials VIII and IX with centrally reviewed pathology data were included. BC subtypes were defined as triple negative (TN; n = 310), human epidermal growth factor receptor 2 (HER2) positive (n = 369), and hormone receptor positive with high (luminal B-like [LB-like]; n = 763) or low (luminal A-like [LA-like]; n = 509) proliferative activity by Ki-67 labeling index. BC-free interval (BCFI) events were invasive BC recurrence in local, contralateral breast, nodal, bone, or visceral sites. Time to first site-specific recurrence was evaluated by using cumulative incidence and competing risks regression analysis. RESULTS Median follow-up was 12.5 years. The 10-year BCFI was higher for patients with LA-like (86%) BC compared with LB-like (76%), HER2 (73%), and TN (71%; P < .001) BC. TN and HER2 cohorts had higher hazard of BCFI event in the first 4 years after diagnosis (pre-trastuzumab). LB-like cohorts had a continuously higher hazard of BCFI event over time compared with LA-like cohorts. Ten-year overall survival was higher for LA-like (89%) compared with LB-like (83%), HER2 (77%), and TN (75%; P < .001) BC. LB-like subtypes had higher rates of bone as first recurrence site than other subtypes (P = .005). Visceral recurrence as first site was lower for the LA-like subgroup, with similar incidence among the other subgroups when treated with chemotherapy (P = .003). CONCLUSION BC subtypes have different distant recurrence patterns over time. Defining different patterns of BC recurrence can improve BC care through surveillance guidelines and can guide the design of clinical studies.

PURPOSE Cognitive-existential group therapy (CEGT) was developed to improve mood and mental attitude toward cancer in women with early-stage breast cancer receiving adjuvant chemotherapy. Given the debate about group therapys association with increased survival in women with metastatic breast cancer, we were curious to check its effect at a much earlier stage in the cancer journey. PATIENTS AND METHODS We randomly assigned 303 women with early-stage breast cancer who were receiving adjuvant chemotherapy to either 20 sessions of weekly group therapy plus three relaxation classes (n = 154) or to a control condition of three relaxation classes alone (n = 149). The primary outcome was survival. RESULTS CEGT did not extend survival; the median survival time was 81.9 months (95% CI, 64.8 to 99.0 months) in the group-therapy women and 85.5 months (95% CI, 67.5 to 103.6 months) in the control arm. The hazard ratio for death was 1.35 (95% CI, 0.76 to 2.39; P = .31). In contrast, histology and axillary lymph node status were significant predictors of survival. Low-grade histology yielded a hazard ratio of 0.342 (95% CI, 0.17 to 0.69), and axillary lymph node-negative status yielded a hazard ratio of 0.397 (95% CI, 0.20 to 0.78). CONCLUSION CEGT does not prolong survival in women with early-stage breast cancer.

OBJECTIVE Our purpose was to determine the frequency of psychiatric morbidity and to assess the quality of life of women with advanced breast cancer. METHODS The 227 women in the sample were recruited in Melbourne, Australia, and were interviewed (prior to intervention) for a randomized controlled trial of supportive-expressive group therapy. The main outcome measures were DSM-IV psychiatric diagnoses plus quality of life data based on the EORTC QLQ-C30 (core) and QLQ-BR23 (breast module) instruments. RESULTS Forty-two percent of the women (97/227) had a psychiatric disorder; 35.7% (81) of these had depression or anxiety or both. Specific diagnoses were minor depression in 58 women (25.6%), major depression in 16 (7%), anxiety disorder in 14 (6.2%), and phobic disorder in 9 (4%). Seventeen (7.5%) women had more than one disorder. In terms of quality of life, one-third felt less attractive, one-quarter were dissatisfied with their body image, and, in most, sexual interest had waned. Menopausal symptoms such as hot flashes affected less than one-third, whereas symptoms of lymphedema were experienced by 26 (11.5%). SIGNIFICANCE Women with advanced breast cancer have high rates of psychiatric and psychological disturbance. Quality of life is substantially affected. Clinicians need to be vigilant in monitoring psychological adjustment as part of a comprehensive biopsychosocial approach.

PURPOSE In an effort to maintain the excellent long-term results achieved with combination chemotherapy for good-prognosis germ cell carcinoma, but to reduce the toxicities encountered, a randomized trial was conducted comparing cisplatin and vinblastine with or without bleomycin. PATIENTS AND METHODS Two hundred eighteen assessable patients with a good prognosis were randomized to receive induction chemotherapy with cisplatin 100 mg/m2 intravenously (IV) day 1 and vinblastine 6 mg/m2 IV days 1 and 2 every 3 weeks (PV) with or without bleomycin 30 mg intramuscularly (IM) weekly (PVB) for a maximum of 12 weeks. Once maximum response was achieved, patients with a complete remission (CR) received two courses of consolidation chemotherapy, while those with residual abnormalities and normal tumor markers underwent surgical resection whenever possible. RESULTS Toxicities encountered in this study were clearly greater for those patients who received bleomycin, with significantly more leukopenia, thrombocytopenia, anemia, alopecia, and renal and pulmonary toxicities. The proportion of patients who achieved CR and had no evidence of disease (resection of all viable malignancy) was 89% for PV and 94% for PVB (P = .29). After a minimum of 4 years of follow-up, relapses have occurred in 7% of patients who received PV and 5% who received PVB. A total of five patients on each therapy arm were successfully treated with further salvage chemotherapy and surgery. Thus, deaths from progressive malignancy have occurred in 15% of patients on PV and 5% on PVB (P = .02), a rate that was partly offset by the higher proportion of toxic deaths with PVB (P = .06). CONCLUSION Despite the toxicities encountered with bleomycin in cisplatin-based combination chemotherapy for these patients, complete deletion of this drug compromises therapeutic efficacy.

BACKGROUND Vascular endothelial growth factor (VEGF) has a crucial role in angiogenesis, and is a valid target in metastatic breast cancer. Motesanib is an investigational oral inhibitor of VEGF receptors. We aimed to determine whether treatment with motesanib plus paclitaxel is better than placebo plus paclitaxel in patients with HER2-negative locally recurrent or metastatic breast cancer. METHODS Between Dec 1, 2006, and July 4, 2008, patients with untreated HER2-negative metastatic breast cancer were randomly assigned (using a randomisation list created by personnel not associated with the study) in a 1:1:1 ratio to paclitaxel (90 mg/m(2) on days 1, 8, and 15 every 3 weeks) plus either masked motesanib 125 mg orally once per day (n=91), masked placebo orally once per day (n=94), or open-label bevacizumab 10 mg/kg intravenously on days 1 and 15 of each 28-day cycle (n=97), after stratification according to adjuvant or neoadjuvant chemotherapy (taxane-containing regimens vs other regimens vs none), number of metastatic sites (<3 vs ≥3), and hormone receptor status (positive vs negative). Placebo was provided as a replica of motesanib 25 mg tablets. The primary endpoint was objective response rate (ORR) based on the population as assigned to treatment. This trial is registered with ClinicalTrials.gov, number NCT00356681. FINDINGS ORRs for the motesanib group and the placebo group did not differ significantly (49%vs 41%; absolute difference 8% [95% CI -6 to 22]; p=0.31). The ORR in the bevacizumab group (52%) was similar to that in the motesanib group. The most common grade 3 or higher adverse events included diarrhoea (18 of 92 patients in the motesanib group, none of 89 patients in the placebo group, and four of 96 patients in the bevacizumab group), fatigue (11, eight, and six), hypertension (11, one, and seven), and peripheral sensory neuropathy (ten, seven, and 19). More patients in the motesanib group had serious adverse events than did those in the placebo or bevacizumab groups (34, 26, and 21 patients, respectively); the most common of these in the motesanib group were gastrointestinal in nature. INTERPRETATION Data from this trial do not support the further investigation of motesanib at this dose and schedule in this population. FUNDING Amgen.

PURPOSE Cancer presenting at the medial site of the breast may have a worse prognosis compared with tumors located in external quadrants. For medial tumors, axillary lymph node staging may not accurately reflect the metastatic potential of the disease. PATIENTS AND METHODS Eight-thousand four-hundred twenty-two patients randomly assigned to International Breast Cancer Study Group clinical trials between 1978 and 1999 were classified as medial site (1,622; 19%) or lateral, central, and other sites (6,800; 81%). Median follow-up was 11 years. RESULTS A statistically significant difference was observed for patients with medial tumors versus those with nonmedial tumors in disease-free survival (DFS; 10-year DFS, 46% v 48%; HR, 1.10; 95% CI, 1.02 to 1.18; P = .01) and overall survival (10-year OS 59% v 61%; HR, 1.09; 1.01 to 1.19; P = .04). This difference increased after adjustment for other prognostic factors (HR, 1.22; 95% CI, 1.13 to 1.32 for DFS; and HR, 1.24; 95% CI, 1.14 to 1.35 for OS; both P = .0001). The risk of relapse for patients with medial presentation was largest for the node-negative cohort and for patients with tumors larger than 2 cm. In the subgroup of 2,931 patients with negative axillary lymph nodes, 10-year DFS was 61% v 67%, and OS was 73% v 80% for medial versus nonmedial sites, respectively (HR 1.33; 95% CI, 1.15 to 1.54; P = .0001 for DFS; and HR 1.40; 95% CI, 1.17 to 1.67; P = .0003 for OS). CONCLUSION Tumor site has a significant prognostic utility, especially for axillary lymph node-negative disease, that should be considered in therapeutic algorithms. New staging procedures such as biopsy of the sentinel internal mammary nodes or novel imaging methods should be further studied in patients with medial tumors.
