ABSTRACT
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.

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.

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.

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.

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.

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.

PURPOSE: Medical practices in oncology are expected to be multidisciplinary, yet few articles studied how this may be concretely applied. In the present study, we evaluated the organization of two multidisciplinary committees, one for breast cancer and one for sarcoma, in a French Comprehensive Cancer Centre. METHODS: Both tumours were specifically chosen so as to emphasise substantial differences in relation with incidence, histological subtypes, management strategy, and scientific evidence. Between 2003 and 2004, 404 decision processes were observed, 210 for sarcoma (26 meetings) and 194 for breast cancer (10 meetings). The number of physicians who took part in the discussions and their medical specialties were systematically noted as well as the number of contradictory discussions, medical specialties represented in these contradictory discussions and the topics of contradiction. The last measured data was whether the final committee's decision was in conformity with the referent preferences or not. All these measures were related to the referent's medical speciality and working place, to the stage of the disease and to the disease management stage. RESULTS: Committees' specificities concerned their organization, referent's medical specialties, the number of participants in discussions and their medical specialties. Discussions in the sarcoma committee tended to be more multidisciplinary, involving more specialties. Initial strategy proposal for one patient was modified during the discussions for 86 patients out of 210 (41%) and for 62 out of 194 (32%) respectively for sarcoma and breast cancer. However, there was no significant difference in the rate of contradictory discussions between breast cancer and sarcoma committees (32% versus 41% respectively; P = 0.08). The rates of contradictory discussions were similar for localized cancers, local relapse and metastasis disease (37%, 41% and 34% respectively; P = 0.86). CONCLUSIONS: The present study reports more than 30% of changes concerning strategy for patient with cancer due to multidisciplinary discussions. This indicates that, providing tumour committees are adapted to the pathologies' characteristics, they can promote a collective and multidisciplinary approach to oncology.

PURPOSE: The treatment strategy for hormone receptor-positive (ER+) HER2-positive (HER2+) metastatic breast cancer has been modified since several randomized trials have proven the effectiveness of anti-HER2 targeted therapy. Previously validated clinical practice guidelines recommending the use of endocrine therapy alone in first line might be changed. METHODS: This study focused on the outcomes of women with ER+ HER2+ metastatic breast cancer receiving first-line endocrine therapy alone at the Léon-Bérard Centre, Lyon, France. RESULTS: Of 290 patients with ER+ HER2+ tumors, 32 (11%) met the criteria for inclusion. The median age was 54 years (29-79 years). Eighteen patients (56%) had only bone and/or soft tissue metastases. Most patients (n = 21; 65%) had only one metastatic site. Fifteen (47%) had histological grade III disease. The median progression free survival (PFS) was 8.2 months (95% CI: 0.1-16.3) and the median overall survival (OS) was 48 months (95% CI: 22.9-72.9). The overall response rate was 25% (95% CI: 11-49%), including one patient with complete response and seven with partial responses. Ten patients (31%) had stable disease. After failure of endocrine therapy, all patients received trastuzumab. The median PFS after first-line chemotherapy was 8.4 months (95% CI: 5.1-11.8). We identified a group of 10 patients with good prognostic factor (tumor grade < 3 tumors and no visceral metastases), for whom median PFS was 15.5 months (95% CI: 7-23). CONCLUSIONS: Our result suggests that first-line endocrine therapy is a viable therapeutic option for a selected population of metastatic breast cancer patients with HER2-positive tumors. Genomic and transcriptomic signature could help to identify tumors that remain dependant of estrogen-signaling pathway.

Prognostic signification of micrometastases ou isolated tumor cells (ITC) has not yet been clearly precised. Management of the axilla in case of micrometastases or ITC depends on the local pratices: no surgical completion or axillary lymph node dissection (ALND). Axillary lymph node status is the most important prognostic factor in patients with breast cancer; morbidity of ALND is now well known whereas its therapeutic benefit has not been demonstrated. This study is based on a retrospective database of 1375 patients who underwent sentinel node (SN) biopsy for breast cancer. In case of micrometastase or ITC in SN with completion axillary dissection, we examined if non-sentinel lymph node status has changed the indications of adjuvant treatments (chimiotherapy or radiotherapy). The results of our study show that non-sentinel lymph node status modify systemic therapy for a very few patients (less than 4% concerning chimiotherapy and less than 15% concerning radiotherapy).

Breast cancer is associated with a low rate of thromboembolic events (TEE) when compared to other cancers, without influence of the histological type on incidence. Risk factors include the stage of cancer, and the patients' profile and management: hospitalization, surgery and presence of a central catheter but also some cytotoxic chemotherapy, tamoxifen, and some anti-angiogenic targeted therapies. The pathophysiology of TEE includes a cross-stimulation phenomenon, involving tumor cells with procoagulant activity, and factors of hemostasis, coagulation and fibrinolysis. Circulating cellular microparticles bearing tissue factor play a major role, as well as thrombogenic platelet interactions with tumor cells via P-selectin. The occurrence of TEE in a cancer patient significantly increases the risk of death. Prevention is framed by recommendations in surgical patients. Curative treatment is based on the use of low molecular weight heparin for at least six months.

Abstract Breast cancer is the most frequently diagnosed cancer in women and 70% of the cases are hormone-dependent. The presence of ERα is one of the most important prognostic factors predictive of response to endocrine therapy in human breast cancers. Resistance to endocrine therapies has become a major public health concern and it appears essential to understand the mechanisms underlying this phenomenon. This review provides insights into the molecular mechanisms associated with resistance to endocrine therapies and presents the different strategies currently developed in pre-clinical models to overcome this resistance.
ABSTRACT
Hormonal dependence of breast cancer has been known for a long time, yet about half of breast cancers with estrogen receptor will not respond to antihormonal therapy. Now, we know that this resistance may be related to a dysfunction of the estrogen pathway, or that of growth factors and particularly the pathway of cell activation PI3K/Akt/mTOR. Prevention of these different mechanisms of resistance could involve combination therapies such as anti-estrogens (SERMs, aromatase inhibitors) with inhibitors of the activity of growth factors that are particularly temsirolimus and everolimus for the activation pathway cell PI3K/Akt/mTOR.

OBJECTIVES. As vascular endothelial growth factor (VEGF) is expressed in ovarian cancer, we assessed the efficacy and safety of bevacizumab (a monoclonal antibody targeting VEGF) plus microtubule targeting agents for heavily pre-treated ovarian carcinoma patients. METHODS. We retrospectively reviewed 43 patients with recurrent epithelial ovarian carcinoma. Combined treatment included bevacizumab with paclitaxel in 32 (74%), docetaxel in 10 (23%), and vinorelbine in one (2.3%) patients, respectively. RESULTS. The median number of combined treatment was six cycles (range 1-29). On RECIST criteria, the objective response rate (ORR) was 40% (16% CR and 24% PR). Clinical benefit (complete response [CR] plus partial response [PR] and stable disease [SD] lasting ≥ 3 months) was 74% (CI95%: 46.7-77%). Median duration of treatment and overall survival were 3.9 months (range 0.2-14.4 months) and 20.1 months (CI95%: 13.8-20.1) respectively. No toxic death was reported. Grade 3-4 toxicity occurred in 30% of patients. Gastrointestinal perforations and fistula occurred in 3 (7%) and 6 (14%) patients, respectively. CONCLUSION. Although being active in terms of ORR, bevacizumab plus microtubule targeting agents - mainly taxanes - leads to a high rate of gastro-intestinal perforations and fistula in heavily pre-treated ovarian carcinoma patients.

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.

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⻳), 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.

Trabectedin is a new marine-derived compound that binds the DNA minor groove and interacts with proteins of the DNA repair machinery. Trabectedin has shown promising single-agent activity in pretreated patients with soft tissue sarcoma, and ovarian and breast cancer, and combination with various other chemotherapeutic drugs seems feasible. Toxicities are mainly hematologic and hepatic, with Grade 3-4 neutropenia and thrombocytopenia observed in approximately 50% and 20% of patients, respectively, and Grade 3-4 elevation of liver enzymes observed in 35%-50% of patients treated with trabectedin. The recently reported results of a large Phase III trial comparing pegylated liposomal doxorubicin (PLD) alone with a combination of PLD and trabectedin in patients with recurrent ovarian cancer showed improved progression-free survival with the combination of trabectedin and PLD, albeit at the price of increased toxicity. Current research focuses on the identification of predictive factors for patients treated with trabectedin, as well as the development of other combinations.
ABSTRACT
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.

BACKGROUND & AIMS: Adjuvant chemotherapy has frequently been associated with weight gain after breast cancer diagnosis. We aimed to prospectively evaluate body weight variations in French patients with early breast cancer. METHODS: This prospective observational study included 272 breast cancer patients who were candidates for adjuvant chemotherapy. Weight and body mass index were measured at baseline visit, then at 9 and 15 months from baseline (6 and 12-month post-chemotherapy). At baseline visit, information on the benefits of weight gain prevention and healthy diet was given by a dietician. Univariate logistic regression was performed to test the association between weight gain and potential predictive factors. RESULTS: Thirty percent of patients gained weight during the year before diagnosis, 26% were overweight and 15% were obese. At one year, the mean weight change was +1.5kg (SD=4.1) and +2.3% (SD=6.0); 60% of the cohort had gained weight, with a median increase of 3.9kg (SD=3.0) and 5.9% (SD=4.4). Reported weight gain during the year before diagnosis appears to be the only factor associated with the absence of post-chemotherapy weight gain (OR=0.54, 95% CI [0.31-0.95], p=0.034). CONCLUSION: Body weight increased in the post-chemotherapy period in French breast cancer survivors, even when given dietary recommendations. Appropriate weight management interventions with nutritional follow-up and physical activity programs are needed.

Lymphopenia is frequent in advanced cancers and predicts the toxicity of chemotherapy. Its effect on relapse and survival is uncertain. Its prognostic value for survival was analyzed in three databases of previously reported prospective multicenter studies: (a) FEC chemotherapy in metastatic breast carcinoma; (b) CYVADIC in advanced soft tissue sarcoma (European Organization for Research and Treatment of Cancer-Soft Tissue and Bone Sarcoma Group 62791); and (c) prospective, consecutive phase III studies of aggressive diffuse large-cell non-Hodgkin's lymphomas conducted at Centre Léon Bérard between 1987 and 1993. Univariate and multivariate analyses of prognostic factors for survival were performed. The incidence of lymphopenia of <1,000/microL before treatment was constant among the series: 25%, 24%, and 27%, respectively. Lymphopenia was significantly more frequent (P < 0.05) in metastatic breast cancer patients with performance status (PS) of >1, non-Hodgkin's lymphoma patients with international prognostic index (IPI) of > 0, and advanced soft tissue sarcoma and metastatic breast cancer patients with bone metastases. Inunivariate analysis, lymphopenia of <1,000/microL significantly correlated to overall survival in patients with metastatic breast cancer (median, 10 versus 14 mo; P < 0.0001), advanced soft tissue sarcoma (median, 5 versus 10 months; P < 0.01), and non-Hodgkin lymphoma (median, 11 versus 94 months; P < 0.0001). In multivariate analysis (Cox model), lymphopenia was an independent prognostic factor for overall survival in metastatic breast cancer [RR (relative risk), 1.8; 95% CI (confidence interval), 1.3-2.4] along with liver metastases and PS; in advanced soft tissue sarcoma (RR, 1.46; 95% CI, 1.0-2.1) along with liver metastases, lung metastases, and PS; and in non-Hodgkin's lymphoma (RR, 1.48; 95% CI, 1.03-2.1) along with IPI. Our findings show that lymphopenia is an independent prognostic factor for overall and progression-free survival in several cancers.
