ABSTRACT
BACKGROUND: The CPS+EG scoring system was initially described in unselected early breast cancer (eBC) patients treated with neoadjuvant chemotherapy (NAC), leading to refined prognostic stratification, and thus helping to select patients for additional post-NAC treatments. It remains unknown whether the performance is the same in new biological breast cancer entities such as the HER2-low subtype. PATIENTS AND METHODS: Outcomes (disease-free (DFS) and overall survival OS)) of 608 patients with HER2-non amplified eBC and treated with NAC were retrospectively analyzed according to CPS-EG score. We compared the prognostic stratification abilities of the CPS+EG in HER2-low and HER2-0 eBC, analyzing ER+ and ER- tumors separately. RESULTS: In ER+ eBC, the CPS+EG scoring system seems to retain a prognostic value, both in HER2-low and HER2-0 tumors, by distinguishing populations with significantly different outcomes (good: score 0-1, poor: score 2-3, and very poor: score 4-5). Using C-indices for DFS and OS, CPS+EG provided the highest prognostic information in ER+ eBC, especially in HER2-0 tumors. In contrast, in ER- eBC, the CPS+EG does not appear to be able to distinguish different outcome groups, either in HER2-low or HER2-0 tumors. In ER- eBC, C-indices for DFS and OS were highest for pathological stage, reflecting the predominant prognostic importance of residual disease in this subtype. CONCLUSIONS: HER2-low status does not influence the prognostic performance of the CPS+EG score. Our results confirm the usefulness of the CPS+EG score in stratifying the prognosis of ER+ eBC after NAC, for both HER2-0 and HER2-low tumors. For ER- eBC, HER2-low status does not influence the performance of the CPS+EG score, which was lower than that of the pathological stage alone.

Purpose: The French standard chemotherapy for osteosarcoma combines high-dose methotrexate (HDM) and etoposide-ifosfamide (EI) in children and adolescents, and API-AI (doxorubicin-cisplatin-ifosfamide) in adults. We herein present the results of M-EI and API-AI in 18- to 25-year-old patients. Methods: Patients, 18-25 years old, received either M-EI or API-AI regimens. M-EI comprised seven M and two EI doses preoperatively then M-EI in standard-risk patients (good histological response without metastasis) and five M-AP (methotrexate-doxorubicin-cisplatin) in high-risk patients (poor histological response, metastasis, and/or unresectable primary), postoperatively. API-AI comprised three API and two AI doses preoperatively, then two AI and two PI in standard-risk patients and five EI in high-risk patients, postoperatively. Results: We analyzed 95 patients 18-25 years of age: 55 received M-EI and 40 API-AI. The groups had similar baseline characteristics. Eighty-nine patients (94%) had surgery. Twenty-nine of 55 M-EI patients (60%) and 16/40 API-AI patients (41%) had good histological responses to preoperative chemotherapy. At 5 years, event-free survival was 50% (95% confidence interval [CI]: 39-60) and overall survival was 65% (95% CI: 54-74). Acute toxicity was similar, without treatment-related deaths. Conclusions: Survival outcomes with M-EI and API-AI were not significantly different. Tolerance was acceptable with both regimens. HDM is thus feasible for young adults. However, our study limitations preclude any definitive conclusions.

Standard adjuvant therapies for breast cancer such as chemotherapy or aromatase inhibitor and LH-RH agonist hormone therapy are associated with significant survival gains but also induce bone loss by aggravating the estrogen deprivation. The bone loss may be substantial, notably during early treatment, and occurs regardless of the baseline bone mineral density values. The objective of developing these recommendations was to achieve a practical consensus among various scientific societies, based on literature review, about osteoporosis prevention and treatment in these patients. The following scientific societies contributed to the work: Société Française de Rhumatologie (SFR), Groupe de Recherche et d'Information sur les Ostéoporoses (GRIO), Groupe Européen d'Etudes des Métastases Osseuses (GEMO), Association Francophone pour les Soins Oncologiques de Support (AFSOS), Société Française de Sénologie et de Pathologie Mammaire (SFSPM), Société Française de Radiothérapie Oncologique (SFRO). Drug prescription and reimbursement modalities in France were taken into account. These recommendations apply to postmenopausal women taking systemic chemotherapy and/or aromatase inhibitor therapy, non-postmenopausal women taking LH-RH agonist therapy, and non-postmenopausal women with persistent amenorrhea 1 year after chemotherapy completion. All women in these three categories should undergo an evaluation of bone health and receive interventions to combat risk factors for bone loss. Patients with a history of severe osteoporotic fracture and/or a T-score value <-2.5 should receive osteoporosis drug therapy. The FRAX® score should be used to guide treatment decisions in patients whose T-score is between -1 and -2.5. General osteoporosis prevention measures should be applied in patients without criteria for osteoporosis drug therapy, who should undergo bone mineral density measurements 18-24 months later if the baseline T-score is<-1 and 3-5 years later if the baseline T-score is>-1. The anti-tumor effect of bisphosphonates and denosumab was not considered when establishing these recommendations.

BACKGROUND: In 2013, the interim analysis of the Protocol for Herceptin as Adjuvant therapy with Reduced Exposure (PHARE) trial could not show that 6 months of adjuvant trastuzumab was non-inferior to 12 months. Here, we report the planned final analysis based on the prespecified number of occurring events. METHODS: PHARE is an open-label, phase 3, non-inferiority randomised trial of patients with HER2-positive early breast cancer comparing 6 months versus 12 months of trastuzumab treatment concomitant with or following standard neoadjuvant or adjuvant chemotherapy. The study was undertaken in 156 centres in France. Eligible patients were women aged 18 years or older with non-metastatic, operable, histologically confirmed adenocarcinoma of the breast and either positive axillary nodes or negative axillary nodes but a tumour of at least 10 mm. Participants must have received at least four cycles of a chemotherapy for this breast cancer and have started receiving adjuvant trastuzumab-treatment. Eligible patients were randomly assigned to either 6 months or 12 months of trastuzumab therapy duration between the third and sixth months of adjuvant trastuzumab. The randomisation was stratified by concomitant or sequential treatment with chemotherapy, oestrogen receptor status, and centre. The primary objective was non-inferiority in the intention-to-treat population in the 6-month group in terms of disease-free survival with a prespecified hazard margin of 1·15. This trial is registered with ClinicalTrials.gov, number NCT00381901. FINDINGS: 3384 patients were enrolled and randomly assigned to either 12 months (n=1691) or 6 months (n=1693) of adjuvant trastuzumab. One patient in the 12-month group and three patients in the 6-month group were excluded, so 1690 patients in each group were included in the intention-to-treat analysis. At a median follow-up of 7·5 years (IQR 5·3-8·8), 704 events relevant to disease-free survival were observed (345 [20·4%] in the 12-month group and 359 [21·2%] in the 6-month group). The adjusted hazard ratio for disease-free survival in the 12-month group versus the 6-month group was 1·08 (95% CI 0·93-1·25; p=0·39). The non-inferiority margin was included in the 95% CI. No differences in effects pertaining to trastuzumab duration were found in any of the subgroups. After the completion of trastuzumab treatment, rare adverse events occurred over time and the safety analysis remained similar to the previously published report. In particular, we found no change in the cardiac safety comparison, and only three additional cases in which the left ventricular ejection fraction decreased to less than 50% have been reported in the 12-month group. INTERPRETATION: The PHARE study did not show the non-inferiority of 6 months versus 12 months of adjuvant trastuzumab. Hence, adjuvant trastuzumab standard duration should remain 12 months.

Soft tissue sarcomas (STS) are rare tumors accounting for less than 1% of human cancers. While the highest incidence of sarcomas is observed in elderly, this population is often excluded or poorly represented in clinical trials. The present study reports on clinicopathological presentation, and outcome of sarcoma patients over 90 recorded in the Netsarc.org French national database. NETSARC (netsarc.org) is a network of 26 reference sarcoma centers with specialized multidisciplinary tumor board (MDTB), funded by the French National Cancer Institute to improve the outcome of sarcoma patients. Since 2010, presentation to an MDTB, second pathological review, and collection of sarcoma patient characteristics and follow-up are collected in a database Information of patients registered from January 1, 2010, to December 31, 2016, in NETSARC were collected, analyzed and compared to the younger population. Patients with sarcomas aged >90 have almost exclusively sarcomas with complex genomics (92.0% vs. 66.3%), are less frequently metastatic (5.3% vs. 14·7%) at diagnosis, have more often superficial tumors (39.8% vs. 14.7%), as well as limbs and head and neck sites (75.2% vs. 38.7%) (all p < 0.001). Optimal diagnostic procedures and surgery were less frequently performed in patients over 90 (p < 0.001). These patients were less frequently operated in NETSARC centers, as compared to those of younger age groups including aged 80-90. However, local relapse-free survival, metastatic relapse-free survival and relapse-free survival were not significantly different from those of younger patients, in the whole cohort, as well as in the subgroup of operated patients. As expected overall survival was worse in patients over 90 (p < 0.001). Patients over 90 who were not operated had worse overall survival than younger patients (9.9 vs. 27.3 months, p < 0.001). Patients with STS diagnosed after 90 have distinct clinicopathological features, but comparable relapse-free survival, unless clinical practice guidelines recommendations are not applied. Standard management should be proposed to these patients if oncogeriatric status allows.

PURPOSE: UNICANCER-PACS08 compared adjuvant FEC (5-FU; epirubicin; cyclophosphamide) then docetaxel to FEC then ixabepilone in poor prognosis early breast cancer (BC). We evaluated whether replacing docetaxel with ixabepilone would increase 5-year disease-free survival (DFS). PATIENTS AND METHODS: Triple-negative breast cancer (TNBC) or oestrogen receptor (ER)+/progesterone receptor (PR)-/HER2- BC patients were randomised to receive standard FEC (3 cycles) followed by 3 cycles of either docetaxel (100 mg/m2) or ixabepilone (40 mg/m2). Radiotherapy was mandatory after conservative surgery; ER+ patients received endocrine therapy. RESULTS: Seven hundred sixty-two patients were enrolled between October 2007 and September 2010. Baseline characteristics were balanced between arms. Median follow-up was 66.7 months. Median DFS was not reached; 5-year DFS rate was 76% with docetaxel and 79% with ixabepilone (hazard ratio [HR] = 0.80; 95% confidence interval [CI] = 0.58-1.10; p = 0.175). Median overall survival (OS) was not reached; 5-year OS rate was 86% versus 84% (HR = 0.97; 95% CI = 0.66-1.42; p = 0.897). TNBC patients treated with ixabepilone had a 23% lower risk of relapse compared to docetaxel (HR for DFS = 0.77; 95% CI = 0.53-1.11; p = 0.168). DFS was longer with ixabepilone than docetaxel in patients with grade II-III lymphocytic infiltration (HR = 0.55; 95% CI = 0.29-1.05; p = 0.063). All patients experienced ≥1 adverse events (AEs): 75% reported grade III-IV AEs and two (<1%) had grade V AEs (both with neutropenia and infection receiving ixabepilone). CONCLUSION: After adjuvant FEC, ixabepilone was comparable to docetaxel for treating poor prognosis early BC patients. The benefit of ixabepilone in subgroups (patients with TNBC and grade II-III lymphocytic infiltration) requires further evaluation.

BACKGROUND: Genome-wide association studies (GWAS) have to date identified 94 genetic variants (single nucleotide polymorphisms (SNPs)) associated with risk of developing breast cancer. A score based on the combined effect of the 94 risk alleles can be calculated to measure the global risk of breast cancer. We aimed to test the hypothesis that the 94-SNP-based risk score is associated with clinico-pathological characteristics, breast cancer subtypes and outcomes in early breast cancer. METHODS: A 94-SNP risk score was calculated in 8703 patients in the PHARE and SIGNAL prospective case cohorts. This score is the total number of inherited risk alleles based on 94 selected SNPs. Clinical data and outcomes were prospectively registered. Genotyping was obtained from a GWAS. RESULTS: The median 94-SNP risk score in 8703 patients with early breast cancer was 77.5 (range: 58.1-97.6). The risk score was not associated with usual prognostic and predictive factors (age; tumor, node, metastasis (TNM) status; Scarff-Bloom-Richardson grade; inflammatory features; estrogen receptor status; progesterone receptor status; human epidermal growth factor receptor 2 (HER2) status) and did not correlate with breast cancer subtypes. The 94-SNP risk score did not predict outcomes represented by overall survival or disease-free survival. CONCLUSIONS: In a prospective case cohort of 8703 patients, a risk score based on 94 SNPs was not associated with breast cancer characteristics, cancer subtypes, or patients' outcomes. If we hypothesize that prognosis and subtypes of breast cancer are determined by constitutional genetic factors, our results suggest that a score based on breast cancer risk-associated SNPs is not associated with prognosis.

AIM: Adjuvant clinical trials in early human epidermal growth factor receptor 2 (HER2)-positive breast cancer have assessed either sequential or concomitant incorporation of trastuzumab with chemotherapy; only the North Central Cancer Treatment Group (NCCTG)-N9831 trial prospectively compared both modalities. In routine trastuzumab has been incorporated into a concurrent regimen with taxane chemotherapy instead of sequential modality on the basis of a positive risk-benefit ratio. This present study assessed sequential versus concomitant administration of adjuvant trastuzumab. METHODS: A population combining patients from Protocol for Herceptin® as Adjuvant therapy with Reduced Exposure (PHARE) a randomised phase III clinical trial (NCT00381901) and SIGNAL (RECF1098) a prospective study specifically designed for Genome-wide Association Studies (GWAS) analyses was studied. In this cohort with 58 months of median follow-up, the comparison in the HER2-positive group of adjuvant trastuzumab and chemotherapy modalities was based on a propensity score methodology. Treatment modalities were based on physician's choice and comparisons adjustment were made by a propensity score methodology. Overall Survival (OS) and Disease-Free Survival (DFS) were estimated using the Kaplan-Meier method, and comparisons between groups were based on the log rank test. RESULTS: The SIGNAL/PHARE cohort included 11,728 breast cancer cases treated in adjuvant setting; some 5502 of them with HER2-positive tumour: 34.5% (1897/5502) were treated by sequential and 65.5% (3605/5502) by concomitant modality of administration for taxane-chemotherapy and trastuzumab. The adjusted comparison found similar OS (HR = 1.01; 95% CI: 0.86-1.19) and similar DFS (HR = 1.08; 95% CI: 0.96-1.21). CONCLUSION: These results suggest that the sequential administration of trastuzumab given after the completion of adjuvant chemotherapy might be as valid as the concomitant administration of trastuzumab and taxane chemotherapy in the adjuvant setting.

Human epidermal growth factor receptor 2-positive breast cancer is a subtype of interest regarding its outcome and the impressive impact of human epidermal growth factor receptor 2 targeted therapy. Constitutional variants may be involved in the aetiology of human epidermal growth factor receptor 2-positive breast cancer, and we propose a case-case study to test the hypothesis that single nucleotide polymorphisms may be associated with human epidermal growth factor receptor 2 status. A Genome-Wide Association Study was used in a cohort of 9836 patients from the SIGNAL/PHARE study (NCT00381901-RECF1098). The main goal was to identify variants specifically related to human epidermal growth factor receptor 2-positive breast cancer. A two-staged genotyping strategy was carried out to cover as large a proportion of the genome as possible. All subjects were genotyped using the Illumina HumanCore Exome chip set. Principal Components Analysis and k-means were then used to characterize the ancestry of the participants. A random sample of subjects from the main "European" cluster was genotyped with the Omni5 chip set. These data were then used to impute missing genotypes from the remaining subjects genotyped only using the HumanCore Exome array. From the 9836 patients, a total of 8703 cases including 3230 patients with human epidermal growth factor receptor 2-positive breast cancer were analyzed. Despite having 80% power to detect an odds ratio of 1.23 in this population, no variant achieved genome-wide significance for association with the occurrence of human epidermal growth factor receptor 2-positive breast cancer vs. any other subtype of breast tumour. Our study was unable to identify constitutional polymorphisms that are strongly associated with human epidermal growth factor receptor 2-positive status among breast cancer patients.
ABSTRACT
PURPOSE: Optimal duration of adjuvant chemotherapy in the treatment of early-stage breast cancer remained to be investigated rigorously for the standard regimens in widespread use in North America (doxorubicin/cyclophosphamide, AC) and Europe (5-fluorouracil/epirubicin/cyclophosphamide, FEC). Whether six cycles of FEC 100 present an advantage, or not, compared with only four cycles was tested directly in a phase III prospective multicentre trial. PATIENTS AND METHODS: Between 2002 and 2006, 1515 women between 18 and 65°years of age, with node negative N(-) high-risk early-stage breast cancer, were included in the study following breast surgery and axillary lymph node dissection or procedure by sentinel node technique. Inclusion in the study required tumour size T ≥ 1 cm and at least one of the high-risk factors: T > 2 cm, negative oestrogen receptor/progesterone receptor (ER- and PR-), Scarff-Bloom-Richardson (SBR) grade II or III and age ≤ 35°years. Patients were randomly assigned to either six FEC 100 (Arm A) or four FEC 100 (Arm B). The trial was powered to detect an absolute difference ≥6% in disease-free survival (DFS) at 5°years. RESULTS: At 6.1°years median follow-up, with 91 (12%) events recorded in Arm A versus 106 (14%) in Arm B, no statistically significant risk increase was associated with four versus six FEC 100: DFS (hazard ratio (HR) = 1.18; CI 95% [0.89-1.56], P = .24) and overall survival (OS) (HR = 1.39; CI 95% [0.91-2.13], P = .12). CONCLUSION: Differences in chemotherapy duration did not induce notably different outcomes in our cohort of high-risk patients.

BACKGROUND: Overweight and weight gain throughout adult life have been associated with increased risk of breast cancer after the menopause. However the role of body weight at a young age and of the timing of weight gain over the lifetime in postmenopausal breast cancer is not well documented. METHODS: We conducted a population-based case-control study on breast cancer in France that included 739 cases and 815 population controls in postmenopausal women. Height, weight at age 20, 40 and 50 as well as weight one year before diagnosis were obtained during in-person interviews. RESULTS: No association between body mass index at the age of 20 years and breast cancer after the menopause was detected. However, we found that postmenopausal breast cancer was associated with weight gain between ages 40 and 50 years (OR per 5 kg/m2 increase in BMI: 1.45 [95%ci 1.06-1.98]). The increased risk of breast cancer associated with weight gain was more consistent in leaner women at age 20, in older postmenopausal women (>65 years), and in women who did not use menopausal hormone therapy. CONCLUSIONS: These findings point to the importance of controlling for weight gain in middle aged-women. The role of low body weight in young adulthood in breast cancer risk after the menopause should be further scrutinized.
ABSTRACT
BACKGROUND: The ovarian yolk sac tumor (OYST) is a very rare malignancy arising in young women. Our objective was to determine whether an early decline in serum alpha-fetoprotein (AFP) during chemotherapy has a prognostic impact. METHODS: This retrospective study is based on prospectively recorded OYST cases at Gustave Roussy (Cancer Treatment Center). Survival curves were estimated using the Kaplan-Meier method. The serum AFP decline was calculated with the formula previously developed and validated in male patients with poor prognosis non-seminomatous germ cell tumors. Univariate and multivariate analyses were performed using the log-rank test and logistic regression, respectively. RESULTS: Data on AFP were available to calculate an early AFP decline in 57 patients. All patients had undergone surgery followed by chemotherapy. The 5-year overall survival (OS) and event-free survival (EFS) rates were 86% (95% CI: 74%-93%) and 84% (95% CI: 73%-91%), respectively. The disease stage, presence of ascites at presentation, use of the BEP regimen, serum AFP half-life and an early AFP decline were significantly predictive factors for OS and EFS in the univariate analysis. The OS rate was 100% and 49% (95% CI: 26%-72%) in patients with a favorable AFP decline and in those with an unfavorable decline, respectively (p<0.001). In the multivariate analysis, only the presence of ascites at diagnosis (RR=7.3, p=0.03) and an unfavorable early AFP decline (RR=16.9, p<0.01) were significant negative predictive factors for OS. CONCLUSIONS: An early AFP decline during chemotherapy is an independent prognostic factor in patients with OYSTs. CONFLICT OF INTEREST STATEMENT: No conflict of interest.

BACKGROUND: Treatment strategies for locally advanced breast cancer in elderly patients too frail to receive neoadjuvant chemotherapy and the introduction of new classes of drugs in the early 2000s have led to the consideration of endocrine therapy as a neoadjuvant treatment for younger hormone receptor (HR)-positive, postmenopausal patients not eligible for primary breast-conserving surgery (BCS). METHODS: This was a multicenter, phase 2, randomized trial designed to evaluate as its primary objective the clinical response rate after up to 6 months of neoadjuvant endocrine therapy (NET) alone in HR-positive/human epidermal growth factor receptor 2 (HER2)-negative patients with 1 mg of anastrozole (arm A) or 500 mg of fulvestrant (arm B). Secondary objectives included the BCS rate, tumor response assessment (breast ultrasound and magnetic resonance imaging), pathological response (Sataloff classification), safety profile, relapse-free survival (RFS), and predictive markers of responses and outcomes. RESULTS: From October 2007 to April 2011, 116 women (mean age, 71.6 years) with operable infiltrating breast adenocarcinoma (T2-T4, N0-N3, M0) were randomized to receive anastrozole or fulvestrant. The clinical response rates at 6 months were 52.6% (95% confidence interval [CI], 41%-64%) in arm A and 36.8% (95% CI, 25%-49%) in arm B. BCS was performed for 57.6% of arm A patients and 50% of arm B patients. The RFS rates at 3 years were 94.9% in arm A and 91.2% in arm B. The Preoperative Endocrine Prognostic Index status was significantly predictive of RFS. Both treatments were well tolerated. CONCLUSIONS: Both drugs are effective and well tolerated as NET in postmenopausal women with HR-positive/HER2-negative breast cancer. NET could be considered a treatment option in this subpopulation.

BACKGROUND: Addition of bevacizumab to standard chemotherapy in the neoadjuvant setting in patients with HER2-negative metastatic breast cancer improves progression-free survival and the proportion of patients achieving pathological complete response. In the BEVERLY-1 (UCBG-0802) trial we aimed to assess the addition of bevacizumab to neoadjuvant and adjuvant chemotherapy in the treatment of patients with HER2-negative inflammatory breast cancer. METHODS: We did this phase 2, single-arm trial at 20 hospitals in France. We enrolled women aged 18 years or older who had non-metastatic HER2-negative inflammatory breast cancer. Patients underwent 3-week treatment cycles, receiving neoadjuvant intravenous fluorouracil (500 mg/m(2)), epirubicin (100 mg/m(2)), cyclophosphamide (500 mg/m(2)), and bevacizumab (15 mg/kg) during cycles 1-4, then docetaxel (100 mg/m(2)) and bevacizumab during cycles 5-8. 2-4 weeks after surgery, patients received adjuvant radiotherapy, hormone therapy (if they had a hormone receptor-positive tumour), and adjuvant intravenous bevacizumab. The primary endpoint was pathological complete response in breast and axillary lymph nodes after neoadjuvant treatment, determined after centralised review in accordance with Sataloff classification and assessed in the intention-to-treat population. Our analysis of toxic effects included all patients who received at least one dose of bevacizumab. The trial is complete and follow-up is ongoing. This study is registered with ClinicalTrials.gov, number NCT00820547. FINDINGS: Between Jan 16, 2009, and Sept 8, 2010, we enrolled 101 patients, one of whom withdrew consent before treatment, leaving 100 patients in the primary endpoint analysis. After neoadjuvant therapy, 19 (19% [95% CI 12-28]; p=0·16) of 100 patients achieved a pathological complete response according to centralised review. The most frequent grade 3-4 events during the neoadjuvant phase were neutropenia (89 [89%] of 100 patients), febrile neutropenia (37 [37%]), and mucositis (23 [23%]) and during the adjuvant phase the most frequent grade 3-4 adverse event was proteinuria (5 [7%] of 75 patients). One (1%) patient died of thrombotic microangiopathy after cycle 1, which was thought to be related to bevacizumab. Two patients (3%) developed transitory heart failure. 48 (48%) patients had serious adverse events, the most frequent of which was febrile neutropenia (28 [28%]). INTERPRETATION: Our results suggest that the addition of bevacizumab to neoadjuvant and adjuvant chemotherapy does not provide clinical benefit to patients with non-metastatic HER2-negative inflammatory breast cancer. Longer follow-up and correlative studies to identify patients who might benefit from bevacizumab are needed. FUNDING: Roche, La Ligue Nationale contre le Cancer, UNICANCER, and Chugai Pharma.

Night work has been associated with risk of breast cancer but this association needs to be confirmed. Because breast cancer is an etiologically heterogeneous disease, we explored the association of night work with breast cancer subtypes defined by tumor status (positive of negative) for estrogen-receptor (ER), progesterone-receptor (PR) and human epidermal growth factor-receptor 2 (HER2). Using the data from a case-control study in France including 975 cases and 1317 controls, we found that the odds ratios for ER+, PR+ or HER2+ breast cancers subtypes were significantly elevated, while no association with night shift work was observed for ER, PR or HER2-negative tumors. After stratification by menopausal status, the associations of night work with receptor-positive breast tumor subtypes were clearly seen in premenopausal women (odds ratios 2.04, 1.98 and 2.80, respectively) but did not appear in postmenopausal women. This study provides evidence that working at night may increase risk of ER, PR and HER2-positive subtypes of breast cancer particularly among premenopausal women.

PURPOSE: The Suppression of Ovarian Function trial showed improved disease control for tamoxifen plus ovarian function suppression (OFS) compared with tamoxifen alone for the cohort of premenopausal patients who received prior chemotherapy. We present the patient-reported outcomes. PATIENTS AND METHODS: The quality-of-life (QoL) analysis includes 1,722 of 2,045 premenopausal patients with hormone receptor-positive breast cancer randomly assigned to receive adjuvant treatment with 5 years of tamoxifen plus OFS or tamoxifen alone. Chemotherapy use before enrollment was optional. Patients completed a QoL form consisting of global and symptom indicators at baseline, every 6 months for 24 months, and annually during years 3 to 6. Differences in the change of QoL from baseline between the two treatments were tested at 6, 24, and 60 months with mixed models for repeated measures with and without chemotherapy and overall. RESULTS: Patients on tamoxifen plus OFS were more affected than patients on tamoxifen alone by hot flushes at 6 and 24 months, by loss of sexual interest and sleep disturbance at 6 months, and by vaginal dryness up to 60 months. Without prior chemotherapy, patients on tamoxifen alone reported more vaginal discharge over the 5 years than patients on tamoxifen plus OFS. Symptom-specific treatment differences at 6 months were less pronounced in patients with prior chemotherapy. Changes in global QoL indicators from baseline were small and similar between treatments over the whole treatment period. CONCLUSION: Overall, OFS added to tamoxifen resulted in worse endocrine symptoms and sexual functioning during the first 2 years of treatment, with variable magnitudes of treatment differences. Short-term differences in symptom-specific QoL, treatment burden, and coping effort between treatment groups were less pronounced for patients with prior chemotherapy, the cohort that benefited most from OFS in terms of disease control.

BACKGROUND: Suppression of ovarian estrogen production reduces the recurrence of hormone-receptor-positive early breast cancer in premenopausal women, but its value when added to tamoxifen is uncertain. METHODS: We randomly assigned 3066 premenopausal women, stratified according to prior receipt or nonreceipt of chemotherapy, to receive 5 years of tamoxifen, tamoxifen plus ovarian suppression, or exemestane plus ovarian suppression. The primary analysis tested the hypothesis that tamoxifen plus ovarian suppression would improve disease-free survival, as compared with tamoxifen alone. In the primary analysis, 46.7% of the patients had not received chemotherapy previously, and 53.3% had received chemotherapy and remained premenopausal. RESULTS: After a median follow-up of 67 months, the estimated disease-free survival rate at 5 years was 86.6% in the tamoxifen-ovarian suppression group and 84.7% in the tamoxifen group (hazard ratio for disease recurrence, second invasive cancer, or death, 0.83; 95% confidence interval [CI], 0.66 to 1.04; P=0.10). Multivariable allowance for prognostic factors suggested a greater treatment effect with tamoxifen plus ovarian suppression than with tamoxifen alone (hazard ratio, 0.78; 95% CI, 0.62 to 0.98). Most recurrences occurred in patients who had received prior chemotherapy, among whom the rate of freedom from breast cancer at 5 years was 82.5% in the tamoxifen-ovarian suppression group and 78.0% in the tamoxifen group (hazard ratio for recurrence, 0.78; 95% CI, 0.60 to 1.02). At 5 years, the rate of freedom from breast cancer was 85.7% in the exemestane-ovarian suppression group (hazard ratio for recurrence vs. tamoxifen, 0.65; 95% CI, 0.49 to 0.87). CONCLUSIONS: Adding ovarian suppression to tamoxifen did not provide a significant benefit in the overall study population. However, for women who were at sufficient risk for recurrence to warrant adjuvant chemotherapy and who remained premenopausal, the addition of ovarian suppression improved disease outcomes. Further improvement was seen with the use of exemestane plus ovarian suppression. (Funded by Pfizer and others; SOFT ClinicalTrials.gov number, NCT00066690.).

BACKGROUND: Poor prognosis germ-cell tumours are only cured in about half of patients. We aimed to assess whether treatment intensification based on an early tumour marker decline will improve progression-free survival for patients with germ-cell tumours. METHODS: In this phase 3, multicentre, randomised trial, patients were enrolled from France (20 centres), USA (one centre), and Slovakia (one centre). Patients were eligible if they were older than 16 years, had evidence of testicular, retroperitoneal, or mediastinal non-seminomatous germ cell tumours based on histological findings or clinical evidence and highly elevated serum human chorionic gonadotropin or alfa-fetoprotein concentrations that matched International Germ Cell Cancer Consensus Group poor prognosis criteria. After one cycle of BEP (intravenous cisplatin [20 mg/m(2) per day for 5 days], etoposide [100 mg/m(2) per day for 5 days], and intramuscular or intravenous bleomycin [30 mg per day on days 1, 8, and 15]), patients' human chorionic gonadotropin and alfa-fetoprotein concentrations were measured at day 18-21. Patients with a favourable decline in human chorionic gonadotropin and alfa-fetoprotein continued BEP (Fav-BEP group) for 3 additonal cycles, whereas patients with an unfavourable decline were randomly assigned (1:1) to receive either BEP (Unfav-BEP group) or a dose-dense regimen (Unfav-dose-dense group), consisting of intravenous paclitaxel (175 mg/m(2) over 3 h on day 1) before BEP plus intravenous oxaliplatin (130 mg/m(2) over 3 h on day 10; two cycles), followed by intravenous cisplatin (100 mg/m(2) over 2 h on day 1), intravenous ifosfamide (2 g/m(2) over 3 h on days 10, 12, and 14), plus mesna (500 mg/m(2) at 0, 3, 7 and 11 h), and bleomycin (25 units per day, by continuous infusion for 5 days on days 10-14; two cycles), with granulocyte-colony stimulating factor (lenograstim) support. Centrally blocked computer-generated randomisation stratified by centre was used. The primary endpoint was progression-free survival and the efficacy analysis was done in the intention-to-treat population. The planned trial accrual was completed in May, 2012, and follow-up is ongoing. This study is registered with ClinicalTrials.gov, number NCT00104676. FINDINGS: Between Nov 28, 2003, and May 16, 2012, 263 patients were enrolled and 254 were available for tumour marker assessment. Of these 51 (20%) had a favourable marker assessment, and 203 (80%) had an unfavourable tumour marker decline; 105 were randomly assigned to the Unfav-dose-dense group and 98 to the Unfav-BEP group. 3-year progression-free survival was 59% (95% CI 49-68) in the Unfav-dose-dense group versus 48% (38-59) in the Unfav-BEP group (HR 0·66, 95% CI 0·44-1·00, p=0·05). 3-year progression-free survival was 70% (95% CI 57-81) in the Fav-BEP group (HR 0·66, 95% CI 0·49-0·88, p=0·01 for progression-free survival compared with the Unfav-BEP group). More grade 3-4 neurotoxic events (seven [7%] vs one [1%]) and haematotoxic events occurred in the Unfav-dose-dense group compared with in the Unfav-BEP group; there was no difference in grade 1-2 febrile neutropenia (18 [17%] vs 18 [18%]) or toxic deaths (one [1%] in both groups). Salvage high-dose chemotherapy plus a stem-cell transplant was required in six (6%) patients in the Unfav-dose-dense group and 16 (16%) in the Unfav-BEP group. INTERPRETATION: Personalised treatment with chemotherapy intensification reduces the risk of progression or death in patients with poor prognosis germ-cell tumours and an unfavourable tumour marker decline.

BACKGROUND: An effective and well tolerated treatment is needed for patients with early HER2-positive breast cancer who do not achieve a pathological complete response after neoadjuvant therapy. The AVATAXHER trial aimed to predict pathological complete response early with the use of PET and to investigate whether the addition of bevacizumab could improve the proportion of patients achieving a pathological complete response in patients unlikely to respond to treatment. METHODS: AVATAXHER was a randomised, open-label, non-comparative, multicentre phase 2 study that enrolled women (≥18 years of age) with early-stage HER2-positive breast cancer from 26 oncology centres in France. Patients initially received two cycles of neoadjuvant docetaxel (100 mg/m(2) intravenously every 3 weeks) plus trastuzumab (8 mg/kg intravenously every 3 weeks then 6 mg/kg intravenously every 3 weeks for the second course). Before the first and second cycles, [(18)F]-fluorodeoxyglucose (FDG) PET was done and the change in standardised uptake value was used to predict pathological complete response in each patient. Patients who were predicted to be responders on PET continued to receive standard therapy. Predicted non-responders were randomly assigned (2:1) to receive four cycles of docetaxel (100 mg/m(2) intravenously every 3 weeks) and trastuzumab (6 mg/kg intravenously every 3 weeks) plus bevacizumab (15 mg/kg intravenously every 3 weeks; group A) or continue on docetaxel plus trastuzumab alone (group B). Randomisation was open label and was done by an adaptive minimisation method. Although investigators and patients were aware of group assignment, the anatomo-pathologist in charge of centralised review of surgical samples and lymph nodes was masked to treatment assignment. The primary endpoint was centrally assessed pathological complete response according to the Chevallier classification. Efficacy analyses were done in the intention-to-treat population. Safety analyses in this Article were done on all patients who received at least one dose of treatment starting from cycle 3. Survival outcomes are not yet mature. This study is registered with ClinicalTrials.gov (NCT01142778) and EUDRACT (2009-013410-26). FINDINGS: Between May 19, 2010, and Oct 1, 2012, 152 patients were recruited for the study. Ten patients were subsequently excluded, leaving 142 patients in the intention-to-treat population. Of these 142 patients, 69 were predicted by [(18)F]-FDG PET to be treatment responders after two cycles of treatment. The 73 predicted non-responders were randomly assigned to group A (n=48) and group B (n=25). Pathological complete responses were noted in 37 (53·6%, 95% CI 41·2-65·7) of the PET responders, 21 (43·8%, 29·5-58·8) of those in group A, and six (24·0%, 9·4-45·1) of those in group B. Incidences of grade 3-4 adverse events were similar in all three groups. The most common grade 3-4 adverse events were neutropenia (four in PET responders, five in group A, and three in group B), febrile neutropenia (one, three, and one, respectively), and myalgia (four, none, and one, respectively). Overall, 24 serious adverse events were reported in 15 patients (PET responders: nine events in four [6%] of 67 patients; group A: 14 events in ten [21%] of 47 patients; group B: one event in one [4%] of 25 patients). No deaths occurred during the study. INTERPRETATION: In patients with HER2-positive breast cancer, early PET assessment can help to identify non-responders to neoadjuvant docetaxel plus trastuzumab therapy. In these patients, the addition of bevacizumab can increase the proportion of patients achieving a pathological complete response. This potential new role for PET and the activity of bevacizumab in this setting need to be confirmed in larger phase 3 trials. FUNDING: Roche France.

Night shift work has been associated with an increased risk of breast cancer pointing to a role of circadian disruption. We investigated the role of circadian clock gene polymorphisms and their interaction with nightwork in breast cancer risk in a population-based case-control study in France including 1126 breast cancer cases and 1174 controls. We estimated breast cancer risk associated with each of the 577 single nucleotide polymorphisms (SNPs) in 23 circadian clock genes. We also used a gene- and pathway-based approach to investigate the overall effect on breast cancer of circadian clock gene variants that might not be detected in analyses based on individual SNPs. Interactions with nightwork were tested at the SNP, gene, and pathway levels. We found that two SNPs in RORA (rs1482057 and rs12914272) were associated with breast cancer in the whole sample and among postmenopausal women. In this subpopulation, we also reported an association with rs11932595 in CLOCK, and with CLOCK, RORA, and NPAS2 in the analyses at the gene level. Breast cancer risk in postmenopausal women was also associated with overall genetic variation in the circadian gene pathway (P=0.04), but this association was not detected in premenopausal women. There was some evidence of an interaction between PER1 and nightwork in breast cancer in the whole sample (P=0.024), although the effect was not statistically significant after correcting for multiple testing (P=0.452). Our results support the hypothesis that circadian clock gene variants modulate breast cancer risk.
