RESUMEN

PURPOSE: The most appropriate criteria and timing for palliative care referral remain a critical issue, especially in patients with metastatic breast cancer for whom long-term chemosensibility and survival are observed. We aimed to compare the impact of early palliative care including formal concertation with oncologists on decision for an additional line of chemotherapy compared with usual oncology care. METHODS: This randomized prospective study enrolled adult women with metastatic breast cancer and visceral metastases with a 3rd- or 4th-line chemotherapy (CT). Patients received usual oncology care with a palliative care consultation only upon patient or oncologist request (standard group, S) or were referred to systematic palliative care consultation including a regular concertation between palliative care team and oncologists (early palliative care group, EPC). The primary endpoint was the rate of an additional CT (4th or 5th line) decision. Quality of life, symptoms, social support and satisfaction were self-evaluated at 6 and 12 months, at treatment discontinuation or 3 months after discontinuation. RESULTS: From January 2009 to November 2012, two authorized cancer centers included 98 women (EPC: 50; S: 48). Thirty-seven (77.1%, 95%CI 62.7-88%) patients in the EPC group had a subsequent chemotherapy prescribed and 36 (72.0%, 95%CI 57.5-83.8%) in the S group (p = 0.646). No differences in symptom control and global quality of life were observed, but less deterioration in physical functioning was reported in EPC (EPC: 0 [- 53-40]; S: - 6; 7 [- 60 to - 20]; p = 0.027). Information exchange and communication were significant improved in EPC (exchange, EPC: - 8.3 [- 30 to + 7]; S: 0.0 [- 17 to + 23]; p = 0.024; communication, EPC: 12.5 [- 8 to - 37]; S: 0.0 [- 21 to + 17]; p = 0.004). CONCLUSION: EPC in metastatic breast cancer patients did not impact the prescription rate of additional chemotherapy in patients a 3rd- or 4th-line chemotherapy for metastatic breast cancer; however, EPC may contribute to alleviate deterioration in physical functioning, while facilitating communication.

RESUMEN

PURPOSE: Endocrine therapy (ET) used to reduce the risk of recurrence in hormone receptor-expressing disease (75% of breast cancers) is associated with worsening of climacteric symptoms with a negative impact on quality of life (QoL). Homeopathy might allow a better management of hot flushes (HF). METHODS: In this multicenter randomized double-blind placebo-controlled phase III study ( ClinicalTrials.gov NCT01246427), we enrolled ≥ 18 years old women with histologically proven non metastatic localized breast cancer, with Eastern Cooperative Oncology Group-Performance Status (ECOG-PS) ≤ 1, treated for at least 1 month with adjuvant ET, and complaining about moderate to severe HF. Patients should not be scheduled for chemotherapy or radiotherapy, and had no associated pathology known to induce HF. After a 2- to 4-week placebo administration, we randomly assigned (1:1) patients with HFS ≥ 10 using an interactive web-based centralized platform to BRN-01 homeopathic medicine complex (Actheane®) in arm A or Placebo (Arm P). Randomization was stratified by adjuvant ET (taxoxifen/aromatase inhibitor) and recruiting site. HF scores (HFS) were calculated as the mean of HF frequencies before randomization, at 4, and at 8 weeks post-randomization (pre-, 4w,- and 8w-) weighted by a 4-level intensity scale. Primary endpoint was assessed at 4-week post-randomization, as the variation between pre- and 4w-HFS. Secondary endpoints included HFS variation between pre- and 8w-HFS, compliance and tolerance assessed 8 weeks after randomization, and QoL and satisfaction assessed at 4- and 8-week post-randomization. RESULTS: Two hundred ninety-nine patients were included, and 138 (46.2%) randomized (A, 65; P, 73). Median 4w-HFS absolute variation (A, - 2.9; P, - 2.5 points, p = 0.756) and relative decrease (A, - 17%; P, - 15%, p = 0.629) were not statistically different. However, 4w-HFS decreased for 46 (75%) in A vs 48 (68%) patients in P arm. 4w-QoL was stable or improved for respectively 43 (72%) vs 51 (74%) patients (p = 0.470). CONCLUSIONS: The efficacy endpoint was not reached, and BRN-01 administration was not demonstrated as an efficient treatment to alleviate HF symptoms due to adjuvant ET in breast cancer patients. However, the study drug administration led to decreased HFS with a positive impact on QoL. Without any recommended treatment to treat or alleviate the HF-related disabling symptoms, Actheane® could be a promising option, providing an interesting support for better adherence to ET, thereby reducing the risk of recurrence with a good tolerance profile.

RESUMEN

BACKGROUND & AIMS: The motivations of patients who consult a homeopathic (GP-Ho) or conventional (GP-CM) general practitioner for supportive care during cancer treatment have not been widely studied. We investigated the reasons why cancer patients consult a GP-Ho versus a GP-CM for supportive care and the GPs' motivations for their prescriptions. METHODS: This observational survey was carried out in France between October 2008 and October 2011. GPs across France were randomly selected and asked to recruit four cancer patients each. At inclusion, the sociodemographic and clinical (including psychological) characteristics and medical history of the patients were recorded by the GPs and the patients noted their quality of life (QoL) and anxiety/depression using the Quality of Life Questionnaire-C30 (QLQ-C30) and Hospital Anxiety and Depression Scale (HADS) self-questionnaires. The main motivations of the patients regarding the type of GP consultation and the main reasons for the GPs' prescriptions were recorded. RESULTS: Six hundred and forty four patients were included in the analysis: 399 consulted a GP-CM (n = 112) and 245 a GP-Ho (n = 73). Patients consulting a GP-Ho were more often female [OR = 1.93; 95%CI: 1.11-3.35; p = 0.02], employed in a professional capacity [OR = 6.57; 95%CI: 1.96-21.99; p = 0.002], have a shorter time since cancer diagnosis [OR = 2.19; 95%CI: 1.24-3.87; p = 0.007], have received targeted anticancer therapy [OR = 3.70; 95%CI: 1.67-8.18; p = 0.001] and have a high QLQ-C30 score for constipation [OR = 1.01; 95%CI: 1.00-1.02; p = 0.001]. Patients mainly consulted a GP-Ho to receive overall care (73.5% vs. 64.9%; p = 0.024) and medicines to prevent anticancer treatment-related side-effects (63.7% vs. 41.4%; p < 0.0001). In contrast, patients consulted a GP-CM to receive psychological care (50.1% vs. 40.8%; p = 0.021) and more information regarding the oncologists' strategic decisions (p < 0.0001). There was a significantly greater prescription of psychotropic drugs by GP-CM (53.7% vs. 22.4%, p < 0.0001). CONCLUSIONS: Patients consulting a GP-Ho or GP-CM had different motivations for seeking supportive care. There was a significantly greater prescription of psychotropic drugs by GP-CM.

RESUMEN

BACKGROUND: We compared standard adjuvant anthracycline chemotherapy with anthracycline-taxane combination chemotherapy in women with operable node-positive breast cancer. Here we report the final, 10-year follow-up analysis of disease-free survival, overall survival, and long-term safety. METHODS: BCIRG 001 was an open label, phase 3, multicentre trial in which 1491 patients aged 18-70 years with node-positive, early breast cancer and a Karnofsky score of 80% or more were randomly assigned to adjuvant treatment with docetaxel, doxorubicin, and cyclophosphamide (TAC) or fluorouracil, doxorubicin, and cyclophosphamide (FAC) every 3 weeks for six cycles. Randomisation was stratified according to institution and number of involved axillary lymph nodes per patient (one to three vs four or more). Disease-free survival was the primary endpoint and was defined as the interval between randomisation and breast cancer relapse, second primary cancer, or death, whichever occurred first. Efficacy analyses were based on the intention-to-treat principle. BCIRG 001 is registered with ClinicalTrials.gov, number NCT00688740. FINDINGS: Enrolement took place between June 11, 1997 and June 3, 1999; 745 patients were assigned to receive TAC and 746 patients were assigned to receive FAC. After a median follow-up of 124 months (IQR 90-126), disease-free survival was 62% (95% CI 58-65) for patients in the TAC group and 55% (51-59) for patients in the FAC group (hazard ratio [HR] 0·80, 95% CI 0·68-0·93; log-rank p=0·0043). 10-year overall survival was 76% (95% CI 72-79) for patients in the TAC group and 69% (65-72) for patients in the FAC group (HR 0·74, 0·61-0·90; log-rank p=0·0020). TAC improved disease-free survival relative to FAC irrespective of nodal, hormone receptor, and HER2 status, although not all differences were significant in these subgroup analyses. Grade 3-4 heart failure occurred in 26 (3%) patients in the TAC group and 17 (2%) patients in the FAC group, and caused death in two patients in the TAC group and four patients in the FAC group. A substantial decrease in left ventricular ejection fraction (defined as a relative decrease from baseline of 20% or more) was seen in 58 (17%) patients who received TAC and 41 (15%) patients who received FAC. Six patients who received TAC developed leukaemia or myelodysplasia, as did three patients who received FAC. INTERPRETATION: Our results provide evidence that the initial therapeutic outcomes seen at the 5-year follow-up with a docetaxel-containing adjuvant regimen are maintained at 10 years. However, a substantial percentage of patients had a decrease in left ventricular ejection fraction, probably caused by anthracycline therapy, which warrants further investigation. FUNDING: Sanofi.

RESUMEN

BACKGROUND: Chemotherapy induced nausea and vomiting (CINV) remains a major problem that seriously impairs the quality of life (QoL) in cancer patients receiving chemotherapy regimens. Complementary medicines, including homeopathy, are used by many patients with cancer, usually alongside with conventional treatment. A randomized, placebo-controlled Phase III study was conducted to evaluate the efficacy of a complex homeopathic medicine, Cocculine, in the control of CINV in non-metastatic breast cancer patients treated by standard chemotherapy regimens. METHODS: Chemotherapy-naïve patients with non-metastatic breast cancer scheduled to receive 6 cycles of chemotherapy including at least three initial cycles of FAC 50, FEC 100 or TAC were randomized to receive standard anti-emetic treatment plus either a complex homeopathic remedy (Cocculine, registered in France for treatment of nausea and travel sickness) or the matching placebo (NCT00409071 clinicaltrials.gov). The primary endpoint was nausea score measured after the 1st chemotherapy course using the FLIE questionnaire (Functional Living Index for Emesis) with 5-day recall. Secondary endpoints were: vomiting measured by the FLIE score, nausea and vomiting measured by patient self-evaluation (EVA) and investigator recording (NCI-CTC AE V3.0) and treatment compliance. RESULTS: From September 2005 to January 2008, 431 patients were randomized: 214 to Cocculine (C) and 217 to placebo (P). Patient characteristics were well-balanced between the 2 arms. Overall, compliance to study treatments was excellent and similar between the 2 arms. A total of 205 patients (50.9%; 103 patients in the placebo and 102 in the homeopathy arms) had nausea FLIE scores > 6 indicative of no impact of nausea on quality of life during the 1st chemotherapy course. There was no difference between the 2 arms when primary endpoint analysis was performed by chemotherapy stratum; or in the subgroup of patients with susceptibility to nausea and vomiting before inclusion. In addition, nausea, vomiting and global emesis FLIE scores were not statistically different at any time between the two study arms. The frequencies of severe (Grade ≥ 2) nausea and vomiting were low in our study (nausea: P: 17.6% vs C: 15.7%, p=0.62; vomiting: P: 10.8% vs C: 12.0%, p=0.72 during the first course). CONCLUSION: This double-blinded, placebo-controlled, randomised Phase III study showed that adding a complex homeopathic medicine (Cocculine) to standard anti-emetic prophylaxis does not improve the control of CINV in early breast cancer patients.

RESUMEN

Although new chemotherapeutic drugs for metastatic breast cancer (MBC) have been approved over the past decade, it is unclear whether this has changed the overall outcome of patients. This study assessed the clinical and economic impacts of these drugs. We retrospectively studied MBC patients receiving chemotherapy in our institution over two time periods, 1994-1998 and 2003-2006. Patient characteristics and outcomes, and treatment characteristics and costs (€, 2008) were compared. Three hundred and one patients were identified, 149 patients in the first cohort and 152 in second one. The median number of lines of chemotherapy was similar in the two cohorts (three lines). The median costs of chemotherapy per patient nearly doubled over time, from 6,272 € in the 1994-1998 cohort to 13,035 € in the 2003-2006 cohort (P < 0.001). No survival difference was observed between the two groups, with a 3-year survival rate estimated to 41% in the 1994-1998 cohort and 44% in the 2003-2006 cohort (P = 0.52). In multivariate analysis, prognostic factors associated with longer overall survival were single metastatic site (HR 0.48; P < 10⁻³), bone metastases (HR = 0.67; P = 0.007) and positive hormone receptors (HR 0.56; P = 0.0002). New chemotherapeutic agents induced a significant cost increase over time. The limited size and heterogeneity of our cohort do not allow any conclusion concerning their impact on survival.

RESUMEN

OBJECTIVE: To assess the efficacy of capecitabine plus docetaxel (XT) versus epirubicin plus docetaxel (ET) as first-line therapy for metastatic breast cancer (MBC). PATIENTS AND METHODS: Patients with no prior chemotherapy for MBC were randomized to 3-weekly cycles of either XT (capecitabine 1,000 mg/m(2) twice daily, days 1-14; docetaxel 75 mg/m(2), day 1) or ET (epirubicin 75 mg/m(2), day 1; docetaxel 75 mg/m(2), day 1). The primary endpoint was non-progression rate 6 months after randomization. The planned sample size was 106 patients based on a randomized, phase II selection design. RESULTS: Between April 2004 and January 2007, 68 patients were randomized, giving 82% power to select the best regimen according to a 6-month non-progression rate. Slow accrual led to premature study termination. Baseline characteristics were generally well balanced between arms. The 6-month non-progression rates were 75.8% with XT versus 65.7% with ET (p = 0.36). After 42 months' median follow-up, median progression-free survival was 12.4 versus 6.8 months, respectively (p = 0.040). The safety profiles were consistent with previous experience. CONCLUSION: Further larger studies are warranted to validate these results. Despite more grade 3 hand-foot syndrome, first-line XT may be a valid alternative to ET, potentially improving efficacy.

RESUMEN

BACKGROUND: The Hermine study observed the use of trastuzumab for metastatic breast cancer (MBC) in routine practice, including patients who received trastuzumab treatment beyond progression (TBP). PATIENTS AND METHODS: The study observed 623 patients for > or = 2 years. Treatment was given according to oncologists' normal clinical practices. Endpoints included duration of treatment, efficacy, and cardiac safety. The TBP subanalysis compared overall survival (OS) in 177 patients who received first-line trastuzumab and either continued trastuzumab for > or = 30 days following progression or stopped at or before progression. RESULTS: The median treatment duration was 13.3 months. In the first-, second-, and third-line or beyond treatment groups, the median time to progression (TTP) were 10.3 months, 9.0 months, and 6.3 months, and the median OS times were 30.3 months, 27.1 months, and 23.2 months, respectively. Heart failure was observed in 2.6% of patients, although no cardiac-associated deaths occurred. In the TBP subanalysis, the median OS duration from treatment initiation and time of disease progression were longer in patients who continued receiving trastuzumab TBP (>27.8 months and 21.3 months, respectively) than in those who stopped (16.8 months and 4.6 months, respectively). However, the groups were not completely comparable, because patients who continued trastuzumab TBP had better prognoses at treatment initiation. The median TTP was longer in patients who continued trastuzumab TBP (10.2 months) than in those who stopped (7.1 months). CONCLUSION: The Hermine findings confirm that the pivotal trials of first-line trastuzumab treatment in MBC patients are applicable in clinical practice. The subanalysis suggests that trastuzumab TBP offers a survival benefit to MBC patients treated with first-line trastuzumab.

RESUMEN

PURPOSE: Patients developing visceral breast cancer metastases generally receive chemotherapy rather than endocrine therapy. Recent aromatase inhibitor studies have reported activity in such patients; therefore, this study formally evaluated anastrozole and exemestane in postmenopausal patients in this setting. PATIENTS AND METHODS: Postmenopausal women with advanced breast cancer and > or = 1 visceral (liver or lung) lesion were randomized to anastrozole (1 mg/day orally) or exemestane (25 mg/day orally) for > or = 8 weeks. The primary endpoint was objective response in visceral lesions based on modified Response Evaluation Criteria in Solid Tumors. Secondary endpoints included clinical benefit (objective response plus stable disease > or = 180 days), overall survival, and adverse events. RESULTS: A total of 130 patients were enrolled, and 128 patients (64 anastrozole, 64 exemestane) were included in the intent-to-treat analysis. Accrual delays caused study closure before the target enrollment (N = 200) was reached, limiting the statistical power of the study. Objective response in visceral sites was approximately 15% in both groups. Clinical benefit in visceral sites was 32% of the patients treated with anastrozole and 38% of the patients treated with exemestane. Median survival was 33.3 months and 30.5 months in the anastrozole and exemestane groups, respectively. Toxicities were similar to those previously reported; however, treatment-related adverse events were more frequent with anastrozole (41%) than with exemestane (31%). Both treatments were generally well tolerated in patients with postmenopausal breast cancer with visceral metastases. CONCLUSION: Efficacy was similar in both treatment groups for all endpoints. Aromatase inhibitors can be considered as a treatment option in postmenopausal patients with hormone receptor-positive visceral breast cancer metastases.

RESUMEN

Central nervous system (CNS) metastases are a major concern in patients with stage IV breast cancer. Recent studies have shown the efficacy of anti-vascular endothelial growth factor drugs on brain tumors, in particular glioblastoma, but none has explored their efficacy and tolerance in breast cancer patients with CNS metastases. We report 4 cases of patients with CNS metastases treated with bevacizumab and paclitaxel. All but 1 had previous whole-brain radiation therapy, performance status 0-2, and radiographic evidence of progressive CNS metastases. Patients received paclitaxel 80 mg/m2 on days 1, 8, and 15, and bevacizumab 10 mg/kg on days 1 and 15. Response was evaluated according to the World Health Organization criteria. Three patients had brain metastases, and 1 had meningeal lesions. Only 1 patient was chemotherapy-naive. Significant antitumor activity was observed, with 1 complete response and 3 partial responses in the CNS metastases. With a mean follow-up of 9 months, duration of response was 11, 10, 8, and 6 months. No patient had extra-CNS progression. This observed antitumor activity suggests efficiency of the combination of bevacizumab and paclitaxel and warrants further evaluation of this combination as an alternative option for the treatment of multiple CNS metastases in breast cancer.

RESUMEN

OBJECTIVE: We sought to review efficacy and toxicity of an 8-day methotrexate (MTX) regimen in the treatment of patients with low-risk gestational trophoblastic neoplasia (GTN) from the French Trophoblastic Disease Reference Center. STUDY DESIGN: Between 1999 and 2006, 142 low-risk GTNs were diagnosed according to International Federation of Gynecology and Obstetrics (FIGO) criteria for GTN and to the FIGO scoring system. We report their characteristics, remission/resistance/recurrence rates, and treatment toxicity. RESULTS: The 8-day MTX regimen achieved a 77.5% remission rate. All patients but 1 (99.9%) achieved remission and remained disease free until the time of analysis. Severe (grade 3 or 4) blood/bone marrow toxicity and metabolic/laboratory toxicity was noted in 4.2% of cases, of which 2 (1.4%) were grade 4. CONCLUSION: For patients with GTN diagnosed according to FIGO criteria and considered low risk according to the FIGO scoring system, an 8-day MTX regimen is an adequate treatment associating a high rate of remission to a low rate of toxicity.

RESUMEN

BACKGROUND: We compared docetaxel plus doxorubicin and cyclophosphamide (TAC) with fluorouracil plus doxorubicin and cyclophosphamide (FAC) as adjuvant chemotherapy for operable node-positive breast cancer. METHODS: We randomly assigned 1491 women with axillary node-positive breast cancer to six cycles of treatment with either TAC or FAC as adjuvant chemotherapy after surgery. The primary end point was disease-free survival. RESULTS: At a median follow-up of 55 months, the estimated rates of disease-free survival at five years were 75 percent among the 745 patients randomly assigned to receive TAC and 68 percent among the 746 randomly assigned to receive FAC, representing a 28 percent reduction in the risk of relapse (P=0.001) in the TAC group. The estimated rates of overall survival at five years were 87 percent and 81 percent, respectively. Treatment with TAC resulted in a 30 percent reduction in the risk of death (P=0.008). The incidence of grade 3 or 4 neutropenia was 65.5 percent in the TAC group and 49.3 percent in the FAC group (P<0.001); rates of febrile neutropenia were 24.7 percent and 2.5 percent, respectively (P<0.001). Grade 3 or 4 infections occurred in 3.9 percent of the patients who received TAC and 2.2 percent of those who received FAC (P=0.05); no deaths occurred as a result of infection. Two patients in each group died during treatment. Congestive heart failure and acute myeloid leukemia occurred in less than 2 percent of the patients in each group. Quality-of-life scores decreased during chemotherapy but returned to baseline levels after treatment. CONCLUSIONS: Adjuvant chemotherapy with TAC, as compared with FAC, significantly improves the rates of disease-free and overall survival among women with operable node-positive breast cancer.

RESUMEN

Adjuvant chemotherapy, initiated following surgery, aims at controlling "microscopic" metastatic disease before its progression to a "clinical" recurrence. Its efficiency in localized breast cancer was officially demonstrated in 1992 in the Early Breast Cancer Trialists' Collaborative Group meta-analysis. This analysis helped clarify the benefits of therapeutic interventions according to progression stage, age and tumour biological features, especially in the presence of hormone receptors. Later on, new trials further defined the benefits of modern therapies, and especially trastuzumab in patients overexpressing HER2. The assessment of the theoretical benefits of adjuvant therapies takes into account the risk of individual recurrence and the potential decrease of the latter following a given therapeutic intervention--this decrease depending on tumor biological features. Deciding whether an adjuvant therapy should be initiated is difficult since benefits (observed in the long term) are often moderate while toxicities (immediately observed) are significant. The development of national and regional therapeutic guidelines markedly diminished the arbitrary aspect of the decision. Developing tools which could help implying the patient in this therapeutic decision is a priority.

RESUMEN

OBJECTIVE: The objective of the study was to describe women registered at the new French Trophoblastic Disease Reference Center and particularly the rates of gestational trophoblastic neoplasia (GTN) after molar pregnancies. STUDY DESIGN: Epidemiological data from a prospective cohort of women registered between November 1999 and November 2004 were analyzed. RESULTS: Four hundred forty-eight women were registered. The referent pathologist reclassified 32% and 5% of assumed partial mole (PM) and complete mole (CM), respectively. GTN developed in 30 of 212 patients with singleton CM (14%) and in 5 of 108 with singleton PM (5%). Among 131 patients with GTN (35 women followed up after registration for a mole and 96 registered for a GTN), 115 (88%) were low-risk and 16 (12%) were high-risk patients according to 2000 International Federation of Gynecology and Obstetrics (FIGO) scoring system. CONCLUSION: Creation of trophoblastic disease reference centers is desirable to improve treatment of patients. Our results will have to be compared with future publications based on the new 2000 FIGO oncology committee recommendations.

RESUMEN

PURPOSE: This randomized, noncomparative, parallel-group study was designed to evaluate the pathologic complete response (pCR) rate of combined doxorubicin plus paclitaxel (AP) and doxorubicin plus cyclophosphamide (AC) as neoadjuvant chemotherapy in patients with previously untreated breast cancer who were unsuitable for conservative surgery. PATIENTS AND METHODS: A total of 200 patients with T2-3, N0-1, M0 disease were randomly assigned in a 2:1 ratio to receive preoperative chemotherapy with either doxorubicin 60 mg/m(2) plus paclitaxel 200 mg/m(2) as a 3-hour infusion (AP) or doxorubicin 60 mg/m(2) plus cyclophosphamide 600 mg/m(2) (AC) every 3 weeks for 4 courses followed by surgery. RESULTS: A pCR (eradication of invasive carcinoma in tumor and in axillary lymph nodes) was found in 16% and 10% of patients in the AP and AC arms, respectively, by study center pathologists, and in 8% and 6% of patients, respectively, by independent pathologists. Patients with pCRs tended to have unifocal disease, tumors with negative hormonal receptor status, and less differentiation (Scarff, Bloom, and Richardson scale grade 3). Breast-conserving surgery was performed in 58% and 45% of patients in the AP and AC arms, respectively. An objective clinical response was achieved in 89% of patients in the AP arm and 70% in the AC arm. At a median follow-up of 31 months, disease-free survival (DFS) was higher in patients who reached pCR versus those without pCR (91% v 70%). CONCLUSION: The encouraging pathologic and clinical responses of patients with breast cancer after neoadjuvant chemotherapy with doxorubicin plus paclitaxel warrant additional investigation of paclitaxel in the neoadjuvant setting of breast cancer management.

RESUMEN

PURPOSE: To assess whether an epirubicin (EPI) -based chemotherapy plus hormonal regimen improves disease-free (DFS) in women older than 65 years, with node-positive, operable breast cancer (BC), relative to tamoxifen (TAM) alone. PATIENTS AND METHODS: A total of 338 patients were randomly assigned after surgery to receive TAM 30 mg/d for 3 years (TAM, n = 164), or EPI 30 mg on days 1, 8, and 15 every 28 days for six cycles plus TAM 30 mg/d for 3 years (EPI-TAM, n = 174). In both arms, patients received radiotherapy, delivered after chemotherapy (CT) in the EPI-TAM group. RESULTS: The 6-year DFS rates were 69.3% with TAM and 72.6% with EPI-TAM (P = .14). The multivariate analysis shows a relative risk of relapse of 1.93 (95% CI, 1.70 to 2.17) with TAM compared with EPI-TAM (P = .005). The 6-year OS, related to disease progression, was 79.1% and 79.8%, respectively (P = .41). Compliance with CT was good: 96.9% of patients received six cycles. The acute toxicity per patient was mild: grade 2 neutropenia in 5.9%, grade 2 anemia in 2.0%, grade 3 nausea or vomiting in 4.6%, and grade 3 alopecia in 7.2%. Five cases (in five patients) of decreased left ventricular ejection fraction occurred after CT: three after adjuvant CT, and two after anthracycline-based CT for relapse. One patient died as a result of dysrhythmia related to carcinomatous lymphangitis. No secondary leukemia occurred. CONCLUSION: This study conducted in node-positive elderly patients demonstrates a significant contribution of a weekly EPI regimen in terms of DFS. Moreover, this regimen is safe for hematologic, nonhematologic, and cardiac toxicities.

RESUMEN

PURPOSE: Although dendritic cells (DC) and T cells can infiltrate primary breast carcinoma, it remains unclear whether the immune response influences the clinical outcome. EXPERIMENTAL DESIGN: T lymphocytes and DC infiltration within primary tumors was investigated in 152 patients with invasive nonmetastatic breast cancer. CD1a, CD3, CD68, CD123, CD207/Langerin, and CD208/DC-LAMP expression was assessed with semiquantitative immunohistochemical analysis. Expression of chemokines involved in DC migration (MIP-3a/CCL20, MIP-3b/CCL19, and 6Ckine/CCL21) was also examined. The correlation between these markers and the characteristics of the tumors, as well as relapse-free and overall survival was analyzed. Significant prognostic parameters were then tested in a validation series. RESULTS: Infiltration by immature CD207/Langerin+ DC was found in a third of the cancers and did not correlate with clinicopathological data. Presence of mature CD208/DC-LAMP+ DC (56%) and CD3+ T cells (82%) strongly correlated with lymph node involvement and tumor grade. Among the chemokines analyzed, only the presence of MIP-3b/CCL19 in 57% of the tumors correlated with prolonged overall survival. CD123+ plasmacytoid DC (pDC) infiltrated 13% of the primary tumors. Their presence was strongly associated with shorter overall survival (93% versus 58% at 60 months) and relapse-free survival (90% versus 37% at 60 months) and was found to be an independent prognostic factor for overall survival and relapse-free survival and confirmed in an independent validation series of 103 patients. CONCLUSIONS: Infiltration by pDC of primary localized breast tumor correlates with an adverse outcome, suggesting their contribution in the progression of breast cancer.

RESUMEN

INTRODUCTION: This phase 2 randomized study evaluated trebananib (AMG 386), a peptide-Fc fusion protein that inhibits angiogenesis by neutralizing the interaction of angiopoietin-1 and -2 with Tie2, in combination with paclitaxel with or without bevacizumab in previously untreated patients with HER2-negative locally recurrent/metastatic breast cancer. METHODS: Patients received paclitaxel 90 mg/m(2) once weekly (3-weeks-on/1-week-off) and were randomly assigned 1:1:1:1 to also receive blinded bevacizumab 10 mg/kg once every 2 weeks plus either trebananib 10 mg/kg once weekly (Arm A) or 3 mg/kg once weekly (Arm B), or placebo (Arm C); or open-label trebananib 10 mg/kg once a week (Arm D). Progression-free survival was the primary endpoint. RESULTS: In total, 228 patients were randomized. Median estimated progression-free survival for Arms A, B, C, and D was 11.3, 9.2, 12.2, and 10 months, respectively. Hazard ratios (95% CI) for Arms A, B, and D versus Arm C were 0.98 (0.61-1.59), 1.12 (0.70-1.80), and 1.28 (0.79-2.09), respectively. The objective response rate was 71% in Arm A, 51% in Arm B, 60% in Arm C, and 46% in Arm D. The incidence of grade 3/4/5 adverse events was 71/9/4%, 61/14/5%, 62/16/3%, and 52/4/7% in Arms A/B/C/D. In Arm D, median progression-free survival was 12.8 and 7.4 months for those with high and low trebananib exposure (AUCss ≥ 8.4 versus < 8.4 mg·h/mL), respectively. CONCLUSIONS: There was no apparent prolongation of estimated progression-free survival with the addition of trebananib to paclitaxel and bevacizumab at the doses tested. Toxicity was manageable. Exposure-response analyses support evaluation of combinations incorporating trebananib at doses > 10 mg/kg in this setting. TRIAL REGISTRATION: ClinicalTrials.gov, NCT00511459.

RESUMEN

PURPOSE: A multicenter phase II study to evaluate the antitumor effect and safety of docetaxel in combination with cisplatin as first-line chemotherapy for advanced ovarian cancer. METHODS: Enrolled in the study were 45 patients who were to receive six courses of docetaxel 75 mg/m(2) plus cisplatin 75 mg/m(2) every 21 days with hydration and steroid prophylaxis after initial debulking surgery. Imaging techniques and radiography were used to assess clinical tumor response, and second-look surgery was required for patients with complete clinical responses and for those without clinically measurable disease. RESULTS: The overall clinical response rate in 29 patients with clinically measurable disease was 58% (41% complete response). A complete pathologic response was seen in 9 of 34 patients who underwent second-look laparotomy, while microscopic disease was found in 10 patients. The median time to progression was 14.4 months (95% CI 8.4-20.4 months), with a median overall survival of 43 months (95% CI 21.1-65.0 months). Patients received a median number of six cycles at a dose intensity of 98%. Grade 3-4 neutropenia was seen in 80% of patients, but was manageable. No patients withdrew because of fluid retention. CONCLUSIONS: The combination of docetaxel with cisplatin confers high clinical and pathologically verified tumor response rates and is well tolerated in the first-line management of advanced ovarian cancer.
