The prognostic value of FIGO staging defined by combining MRI and [ 18F]FDG PET/CT in patients with locally advanced cervical cancer. Curr Probl Cancer 2023; 47:101007. [PMID: 37684197 DOI: 10.1016/j.currproblcancer.2023.101007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2023] [Revised: 08/08/2023] [Accepted: 08/16/2023] [Indexed: 09/10/2023]
Abstract
The last version of the FIGO classification recommended imaging tools to complete the clinical assessment of patients with cervical cancer. However, the preferable imaging approach is still unclear. We aimed to explore the prognostic power of Magnetic Resonance Imaging (MRI), contrast-enhanced Computed Tomography (ceCT), and [18F]-Fluorodeoxyglucose Positron Emission Tomography ([18F]FDG-PET)/CT in patients staged for locally advanced cervical cancer (LACC, FIGO stages IB3-IVA). Thirty-six LACC patients (mean age 55.47 ± 14.01, range 31-82) were retrospectively enrolled. All of them underwent MRI, ceCT and [18F]FDG-PET/CT before receiving concurrent chemoradiotherapy. A median dose of 45 Gy (range 42-50.4; 25-28 fractions, 5 fractions per week, 1 per day) was delivered through the external-beam radiation therapy (EBRT) on the pelvic area, while a median dose of 57.5 Gy (range 16-61.1; 25-28 fractions, 5 fractions per week, 1 per day) was administered on metastatic nodes. The median doses for brachytherapy treatment were 28 Gy (range 28-30; 4-5 fractions, 1 every other day). Six cycles of cisplatin or carboplatin were administered weekly. The study endpoints were recurrence-free survival (RFS) and overall survival (OS). Metastatic pelvic lymph nodes at MRI independently predicted RFS (HR 13.271, 95% CI 1.730-101.805; P = 0.027), while metastatic paraaortic lymph nodes at [18F]FDG-PET/CT independently predicted both RFS (HR 11.734, 95% CI 3.200-43.026; P = .005) and OS (HR 13.799, 95% CI 3.378-56.361; P < 0.001). MRI and [18F]FDG-PET/CT findings were incorporated with clinical evidences into the FIGO classification. With respect to the combination of clinical, MRI and ceCT data, the use of next-generation imaging (NGI) determined a stage migration in 10/36 (27.7%) of patients. Different NGI-based FIGO classes showed remarkably different median RFS (stage IIB: not reached; stage IIIC1: 44 months; stage IIIC2: 3 months; P < 0.001) and OS (stage IIB: not reached; stage IIIC1: not reached; stage IIIC2: 14 months; P < 0.001). A FIGO classification based on the combination of MRI and [18F]FDG-PET/CT might predict RFS and OS of LACC patients treated with concurrent chemoradiotherapy.

Approaches to Fertility Preservation for Young Women With Breast Cancer. Clin Breast Cancer 2023; 23:241-248. [PMID: 36710145 DOI: 10.1016/j.clbc.2023.01.006] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2022] [Revised: 12/23/2022] [Accepted: 01/10/2023] [Indexed: 01/15/2023]
Abstract
In patients with early breast cancer, the combination of different systemic treatment strategies, including chemotherapy, endocrine therapy, targeted therapy, and more recently also immunotherapy has demonstrated to significantly improve their survival outcomes. However, this gain is often obtained at the cost of higher toxicity calling for the need of increased attention toward survivorship-related issues, including fertility preservation in young women. According to available guidelines, health care providers should offer oncofertility counseling to all patients with cancer diagnosed at reproductive age. Counselling should focus on the risk of gonadotoxicity of anticancer treatments and on the access to fertility preservation techniques. However, several surveys have demonstrated suboptimal implementation of these recommendations. This review aims at summarizing the available evidence on oncofertility to guide health care providers involved in the management of young women with breast cancer. Available and effective options for fertility preservation include oocyte/embryo cryopreservation or ovarian tissue cryopreservation. Patient, disease, and treatment characteristics should be carefully considered when offering these strategies. Ovarian function preservation with gonadotrophin-releasing hormone agonists during chemotherapy should be discussed and offered to every premenopausal woman concerned about developing premature ovarian insufficiency and independently of her wish to preserve fertility. Current available data confirm that pregnancy occurring after proper treatment for breast cancer is safe, both in terms of long-term clinical outcomes and for the babies. Fertility preservation and pregnancy desire should be pivotal components of the multimodal management of breast cancer in young women, and require a multidisciplinary approach based on close collaborations between oncologists and fertility specialists.

Abstract
OBJECTIVE Neoadjuvant chemotherapy has become the preferred treatment in HER2-positive early breast cancer. Several trials investigated the neoadjuvant efficacy of dual HER2 blockade with anthracycline-free chemotherapy, whereas few data are available on single-agent trastuzumab and anthracycline-based regimens, which represent the standard of care in the adjuvant setting. This phase II, single-arm trial assessed anthracycline-based chemotherapy and trastuzumab as neoadjuvant treatment for high-risk HER2-positive breast cancer. METHODS Forty-three patients with stage II-III HER2-positive breast cancer were treated with 4 courses of neoadjuvant 5-fluorouracil 600 mg/m2, epirubicin 90 mg/m2, cyclophosphamide 600 mg/m2 (FEC ×4) every 21 days, followed by 12 courses of weekly paclitaxel 80 mg/m2 and trastuzumab 2 mg/Kg IV (loading dose 4 mg/kg). RESULTS Pathologic complete response (pCR) was observed in 22 (51%) of 43 patients. After a median follow-up of 6 years, the 5-year disease-free survival and overall survival were 85.8% (95% confidence interval 75.9%-97%) and 89.6% (80.4%-99.8%), respectively. A temporary decrease in left ventricular ejection fraction was observed in two patients. No cardiac death or congestive heart failure occurred. One patient died due to febrile neutropenia. CONCLUSIONS FEC ×4 followed by paclitaxel and trastuzumab was associated with high pCR rates and favorable long-term outcomes. However, this regimen was associated with relevant hematologic toxicity.

PARP-inhibitors for BRCA1/2-related advanced HER2-negative breast cancer: A meta-analysis and GRADE recommendations by the Italian Association of Medical Oncology. Breast 2022; 66:293-304. [PMID: 36379199 PMCID: PMC9663524 DOI: 10.1016/j.breast.2022.10.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2022] [Revised: 10/21/2022] [Accepted: 10/23/2022] [Indexed: 11/09/2022] Open
Abstract
BACKGROUND Approximately 5-10% of unselected breast cancer (BC) patients retain a hereditary predisposition related to a germline mutation in BRCA1/2 genes. The poly-ADP ribose polymerase (PARP)-inhibitors olaparib and talazoparib have been granted marketing authorization by both FDA and EMA for adults with BRCA1/2 germline mutations and HER2-negative (HER2-) advanced BC based on the results from the phase III OlympiAd and EMBRACA trials. METHODS The panel of the Italian Association of Medical Oncology (AIOM) Clinical Practice Guidelines on Breast Cancer addressed two critical clinical questions, adopting the Grades of Recommendation, Assessment, Development and Evaluation (GRADE) approach and the Evidence to Decision framework (EtD), to develop recommendations on the use of PARP-inhibitors, with respect to single-agent chemotherapy, in patients with BRCA-related triple-negative (clinical question 1) and hormone receptor-positive (HR+)/HER2- (clinical question 2) advanced BC. RESULTS Two studies were eligible (OlympiAd and EMBRACA). For both clinical questions, the Panel judged the benefit/harm balance probably in favor of the intervention, given the favorable impact in terms of PFS, ORR, and QoL at an acceptable cost in terms of toxicity; the overall certainty of the evidence was low. The panel's final recommendations were conditional in favor of PARP-inhibitors over single-agent chemotherapy in both HR+/HER2-and triple-negative BC. Finally, the Panel identified and discussed areas of uncertainty calling for further exploration. CONCLUSIONS The Panel of AIOM BC Clinical Practice Guideline provided clinical recommendations on the use of PARP-inhibitors, with respect to single-agent chemotherapy, in patients with BRCA-related HER2-advanced BC by adopting the GRADE methodology.

Abstract
Abstract
Study question
How (neo)adjuvant chemotherapy and concurrent administration of luteinizing hormone-releasing hormone agonist (LHRHa) affect Anti-Mullerian hormone (AMH) and estradiol level dynamics in premenopausal breast cancer patients.
Summary answer
Breast cancer chemotherapy has a major negative impact on patients’ ovarian function and reserve. Women receiving LHRHa showed higher probability of long-term ovarian function recovery.
What is known already
The risk of developing treatment-induced premature ovarian insufficiency (POI) and infertility following chemotherapy is among the most important concern in premenopausal breast cancer patients.
AMH is a promising biomarker for assessing treatment-induced gonadotoxicity in patients receiving anticancer therapies.
Concurrent administration of LHRHa with chemotherapy is associated with a lower risk of treatment-induced ovarian failure and higher rates of menstrual function recovery. However, data on the impact of LHRHa during chemotherapy on patients’ ovarian reserve are still insufficient.
Study design, size, duration
Between 2003 and 2008, the PROMISE-GIM6 trial randomized 281 premenopausal early breast cancer women to receive chemotherapy alone (control group) or chemotherapy plus triptorelin (LHRHa group). Primary endpoints were incidence of early menopause and long-term ovarian function. For exploratory purposes in a subset of patients, AMH and estradiol levels were measured at baseline, <3 months after last cycle of chemotherapy, 1 year after last cycle of chemotherapy, and at the end of adjuvant endocrine treatment.
Participants/materials, setting, methods
The main results of the trial showed that use of concurrent LHRHa significantly reduced the risk of early menopause, increased the chances of long-term ovarian function recovery and did not influence survival outcomes (JAMA 2011, JAMA 2015, JNCI 2022). The present exploratory analysis reports on dynamics of ovarian biomarkers (AMH and estradiol) at baseline and following (neo)adjuvant chemotherapy.
Main results and the role of chance
Out of 281 enrolled patients, 48 enrolled at the coordinating centers had at least one measurement of AMH and estradiol levels at baseline and after (neo)adjuvant chemotherapy. Baseline patient characteristics were similar between treatment arms, with median age being 41 and 39 years, and median AMH levels being 3.9 and 4.9 mcg/L in the control and LHRHa groups, respectively.
In the overall population, estradiol levels showed a significant decrease at the end of chemotherapy, a significant increase after one year, and a return to baseline values at the end of endocrine therapy. By contrast, AMH levels showed a constant decrease over time.
As compared to patients in the control group, those in the LHRHa group had a significant reduction in the risk of early menopause (p = 0.02) and significantly higher estradiol levels at the end of chemotherapy and 1 year after chemotherapy (p < 0.001), suggesting a higher probability of ovarian function recovery. By contrast, no significant differences were observed in the AMH level dynamics between patients receiving LHRHa and those who did not.
Limitations, reasons for caution
Relatively small number of included patients (n = 48) and small number of patients with AMH and estradiol levels determined at each timepoint.
Wider implications of the findings
This biomarker analysis within a phase III randomized trial confirmed that patients receiving LHRHa had a higher probability of ovarian function recovery also supported by estradiol dynamics. However, both patients in the LHRHa and control group showed a major decline in AMH levels after chemotherapy that persisted over time.

Abstract
Breast cancer is the most frequent malignancy diagnosed in premenopausal women. In this age group, breast tumors tend to be diagnosed at more advanced stages and to harbor more aggressive biological features. In addition, specific age-related issues including genetic counseling, fertility preservation, impact on social and couple relationships, working life, and management of long-term side effects should be considered highly relevant when managing early breast cancer in premenopausal women. Therefore, the care of these patients is particularly complex and a multidisciplinary approach is mandatory. The present review summarizes the current state of art in the adjuvant systemic treatment of premenopausal women with early breast cancer focusing on the optimal chemotherapy, endocrine therapy, and targeted therapy approaches in this specific patient population.

Inclusion of Platinum Agents in Neoadjuvant Chemotherapy Regimens for Triple-Negative Breast Cancer Patients: Development of GRADE (Grades of Recommendation, Assessment, Development and Evaluation) Recommendation by the Italian Association of Medical Oncology (AIOM). Cancers (Basel) 2019; 11:cancers11081137. [PMID: 31398896 PMCID: PMC6721549 DOI: 10.3390/cancers11081137] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2019] [Revised: 08/01/2019] [Accepted: 08/02/2019] [Indexed: 02/06/2023] Open
Abstract
In the absence of identified therapeutic targets, chemotherapy is the main systemic treatment option for triple-negative breast cancer (TNBC). The achievement of a pathological complete response (pCR) after neoadjuvant chemotherapy leads to good outcome, whereas patients not achieving a pCR are at high risk of relapse. Various trials have evaluated the inclusion of platinum in neoadjuvant chemotherapy regimens for TNBC, leading to non-univocal results. The panel of the Italian Association of Medical Oncology (AIOM) Guidelines on Breast Cancer developed a clinical recommendation on the addition of platinum to anthracycline/taxane-based neoadjuvant chemotherapy for TNBC by using the Grades of Recommendation, Assessment, Development, and Evaluation (GRADE) methodology and the Evidence to Decision framework (EtD). Five studies were eligible. The panel identified the following outcomes of benefit: pCR (critical), disease/event-free survival (DFS/EFS, critical), and overall survival (OS, critical). The panel identified febrile neutropenia (critical), serious adverse events (critical), anemia grade 3–4 (important), thrombocytopenia grade 3–4 (important) as outcomes of harms. The probability of pCR was higher in the platinum-based chemotherapy group versus control group (RR = 1.45, 95%CI 1.28–1.64); however, no impact on long-term outcome was observed. Neoadjuvant treatment regimens containing platinum resulted in a non-significant increase in the risk of febrile neutropenia and in a significant increase in the risk serious adverse events, G3–G4 anemia and G3–G4 thrombocytopenia: 11.3% versus 0.8%, RR = 15.66 (95%CI 6.38–38.44). The panel judged uncertain/favorable the benefit/harms balance. The panel’s final recommendation was conditional in favor of the inclusion of platinum in anthracycline/taxane-based neoadjuvant regimens for TNBC.

Adjuvant endocrine therapy in premenopausal patients with hormone receptor-positive early breast cancer: Evidence evaluation and GRADE recommendations by the Italian Association of Medical Oncology (AIOM). Eur J Cancer 2018; 99:9-19.

Abstract
Premenopausal women with hormone receptor-positive early breast cancer are candidates for adjuvant endocrine therapy, as recommended by the major international guidelines. To date, adjuvant endocrine options for premenopausal women include tamoxifen with or without ovarian function suppression (OFS) or an aromatase inhibitor with OFS. Multiple strategies for endocrine treatment of premenopausal women with hormone-responsive breast cancer have been assessed, and the results of randomised clinical trials have been reported over the last years. Despite this evidence, the optimal algorithm for endocrine therapy for premenopausal women with hormone receptor-positive early stage invasive breast cancer shows open questions regarding the role of OFS in addition to tamoxifen and the optimal use of hormonal agents. The panel of the Italian Association of Medical Oncology (AIOM) Clinical Practice Guidelines on Breast Cancer applied the Grades of Recommendation, Assessment, Development and Evaluation (GRADE) methodology on three critical questions on the choice of the adjuvant hormonal therapy in premenopausal breast cancer patients to summarise available evidence and to create recommendations to help physicians in their clinical practice.

Adjuvant anastrozole versus exemestane versus letrozole, upfront or after 2 years of tamoxifen, in endocrine-sensitive breast cancer (FATA-GIM3): a randomised, phase 3 trial. Lancet Oncol 2018; 19:474-485. [PMID: 29482983 DOI: 10.1016/s1470-2045(18)30116-5] [Citation(s) in RCA: 43] [Impact Index Per Article: 7.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2017] [Revised: 01/04/2018] [Accepted: 01/08/2018] [Indexed: 01/04/2023]
Abstract
BACKGROUND Uncertainty exists about the optimal schedule of adjuvant treatment of breast cancer with aromatase inhibitors and, to our knowledge, no trial has directly compared the three aromatase inhibitors anastrozole, exemestane, and letrozole. We investigated the schedule and type of aromatase inhibitors to be used as adjuvant treatment for hormone receptor-positive early breast cancer. METHODS FATA-GIM3 is a multicentre, open-label, randomised, phase 3 trial of six different treatments in postmenopausal women with hormone receptor-positive early breast cancer. Eligible patients had histologically confirmed invasive hormone receptor-positive breast cancer that had been completely removed by surgery, any pathological tumour size, and axillary nodal status. Key exclusion criteria were hormone replacement therapy, recurrent or metastatic disease, previous treatment with tamoxifen, and another malignancy in the previous 10 years. Patients were randomly assigned in an equal ratio to one of six treatment groups: oral anastrozole (1 mg per day), exemestane (25 mg per day), or letrozole (2·5 mg per day) tablets upfront for 5 years (upfront strategy) or oral tamoxifen (20 mg per day) for 2 years followed by oral administration of one of the three aromatase inhibitors for 3 years (switch strategy). Randomisation was done by a computerised minimisation procedure stratified for oestrogen receptor, progesterone receptor, and HER2 status; previous chemotherapy; and pathological nodal status. Neither the patients nor the physicians were masked to treatment allocation. The primary endpoint was disease-free survival. The minimum cutoff to declare superiority of the upfront strategy over the switch strategy was assumed to be a 2% difference in disease-free survival at 5 years. Primary efficacy analyses were done by intention to treat; safety analyses included all patients for whom at least one safety case report form had been completed. Follow-up is ongoing. This trial is registered with the European Clinical Trials Database, number 2006-004018-42, and ClinicalTrials.gov, number NCT00541086. FINDINGS Between March 9, 2007, and July 31, 2012, 3697 patients were enrolled into the study. After a median follow-up of 60 months (IQR 46-72), 401 disease-free survival events were reported, including 211 (11%) of 1850 patients allocated to the switch strategy and 190 (10%) of 1847 patients allocated to upfront treatment. 5-year disease-free survival was 88·5% (95% CI 86·7-90·0) with the switch strategy and 89·8% (88·2-91·2) with upfront treatment (hazard ratio 0·89, 95% CI 0·73-1·08; p=0·23). 5-year disease-free survival was 90·0% (95% CI 87·9-91·7) with anastrozole (124 events), 88·0% (85·8-89·9) with exemestane (148 events), and 89·4% (87·3 to 91·1) with letrozole (129 events; p=0·24). No unexpected serious adverse reactions or treatment-related deaths occurred. Musculoskeletal side-effects were the most frequent grade 3-4 events, reported in 130 (7%) of 1761 patients who received the switch strategy and 128 (7%) of 1766 patients who received upfront treatment. Grade 1 musculoskeletal events were more frequent with the upfront schedule than with the switch schedule (924 [52%] of 1766 patients vs 745 [42%] of 1761 patients). All other grade 3-4 adverse events occurred in less than 2% of patients in either group. INTERPRETATION 5 years of treatment with aromatase inhibitors was not superior to 2 years of tamoxifen followed by 3 years of aromatase inhibitors. None of the three aromatase inhibitors was superior to the others in terms of efficacy. Therefore, patient preference, tolerability, and financial constraints should be considered when deciding the optimal treatment approach in this setting. FUNDING Italian Drug Agency.

The PREgnancy and FERtility (PREFER) study: an Italian multicenter prospective cohort study on fertility preservation and pregnancy issues in young breast cancer patients. BMC Cancer 2017; 17:346. [PMID: 28526012 PMCID: PMC5437418 DOI: 10.1186/s12885-017-3348-8] [Citation(s) in RCA: 23] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2016] [Accepted: 05/12/2017] [Indexed: 12/30/2022] Open
Abstract
Background Fertility and pregnancy issues are of key importance for young breast cancer patients. Despite several advances in the field, there are still multiple unmet needs and barriers in discussing and dealing with these concerns. To address the significant challenges related to fertility and pregnancy issues, the PREgnancy and FERtility (PREFER) study was developed as a national comprehensive program aiming to optimize care and improve knowledge around these topics. Methods The PREFER study is a prospective cohort study conducted across several Italian institution affiliated with the Gruppo Italiano Mammella (GIM) group evaluating patterns of care and clinical outcomes of young breast cancer patients dealing with fertility and pregnancy issues. It is composed of two distinctive studies: PREFER-FERTILITY and PREFER-PREGNANCY. The PREFER-FERTILITY study is enrolling premenopausal patients aged 18–45 years, diagnosed with non-metastatic breast cancer, who are candidates to (neo)adjuvant chemotherapy and not previously exposed to anticancer therapies. The primary objective is to obtain and centralize data about patients’ preferences and choices towards the available fertility preserving procedures. The success and safety of these strategies and the hormonal changes during chemotherapy and study follow-up are secondary objectives. The PREFER-PREGNANCY study is enrolling survivors achieving a pregnancy after prior history of breast cancer and patients diagnosed with pregnancy-associated breast cancer (PABC). The primary objectives are to obtain and centralize data about the management and clinical outcomes of these women. Patients’ survival outcomes, and the fetal, obstetrical and paediatric care of their children are secondary objectives. For both studies, the initial planned recruitment period is 5 years and patients will remain in active follow-up for up to 15 years. The PREFER-FERTILITY study was first activated in November 2012, and the PREFER-PREGNANCY study in May 2013. Discussion The PREFER study is expected to support and improve oncofertility counseling in Italy, to explore the real need of fertility preserving procedures, and to acquire prospectively more robust data on the efficacy and safety of the available strategies for fertility preservation, on the management of breast cancer survivors achieving a pregnancy and of women with PABC (including the possible short- and long-term complications in their children). Trial registration number ClinicalTrials.gov identifier: NCT02895165 (Retrospectively registered in August 2016).

Concurrent versus sequential adjuvant chemo-endocrine therapy in hormone-receptor positive early stage breast cancer patients: a systematic review and meta-analysis. Breast 2017; 33:104-108. [PMID: 28360014 DOI: 10.1016/j.breast.2017.03.011] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2017] [Accepted: 03/22/2017] [Indexed: 11/18/2022] Open
Abstract
BACKGROUND Although in clinical practice adjuvant chemotherapy (CT) and endocrine therapy (ET) are administered sequentially in patients with hormone-receptor positive breast cancer, the optimal timing, i.e. concurrent or sequential administration, of these treatments has been scarcely investigated. To better clarify this issue we conducted a systematic review and meta-analysis of randomized studies comparing these two modalities of administrations in terms of disease-free survival (DFS) and overall survival (OS). METHODS Relevant studies were identified by searching PubMed, Web of Knowledge and the proceedings of the major conferences with no date restriction up to March 2016. The summary risk estimates (pooled hazard ratio [HR] and 95% confidence intervals [CI]) for DFS and OS were calculated using random effect models (DerSimonian and Laird method). RESULTS A total of three randomized studies were eligible including 2021 breast cancer patients. Overall, 755 DFS events were observed, 365 in the sequential arm and 390 in the concomitant arm, with a pooled HR of 0.95 (95% CI = 0.76 to 1.18, P = 0.643). No association between timing of treatment and OS was observed (HR = 0.95; 95% CI = 0.80 to 1.12, P = 0.529). CONCLUSION Our pooled analysis showed no association between the timing of administration of adjuvant CT and ET and DFS and OS in breast cancer patients candidates for both adjuvant treatments. Because of the small number of published trials, the lack of data on the timing with modern adjuvant treatments, i.e. taxane-containing CT and aromatase inhibitors, this topic remain still controversial and requires further studies to be clarified.

BACKGROUND No evidence exists to recommend a specific chemotherapy regimen in young breast cancer patients. We performed a pooled analysis of two randomised clinical trials to evaluate the efficacy of adjuvant dose-dense chemotherapy in premenopausal breast cancer patients and its impact on the risk of treatment-induced amenorrhoea. PATIENTS AND METHODS In the MIG1 study, node-positive or high-risk node-negative patients were randomised to 6 cycles of fluorouracil/epirubicin/cyclophosphamide every 2 (dose-dense) or 3 (standard-interval) weeks. In the GIM2 study, node-positive patients were randomised to 4 cycles of dose-dense or standard-interval EC or FEC followed by 4 cycles of dose-dense or standard-interval paclitaxel. Using individual patient data, the hazard ratio (HR) for overall survival by means of a Cox proportional hazards model and the odds ratio for treatment-induced amenorrhoea through a logistic regression model were calculated for each study. A meta-analysis of the two studies was performed using the random effect model to compute the parameter estimates. RESULTS A total of 1,549 patients were included. Dose-dense chemotherapy was associated with a significant improved overall survival as compared to standard-interval chemotherapy (HR, 0.71; 95% confidence intervals [CI], 0.54-0.95; p = 0.021). The pooled HRs were 0.78 (95% CI, 0.54-1.12) and 0.65 (95% CI, 0.40-1.06) for patients with hormone receptor-positive and -negative tumours, respectively (interaction p = 0.330). No increased risk of treatment-induced amenorrhoea was observed with dose-dense chemotherapy (odds ratio, 1.00; 95% CI, 0.80-1.25; p = 0.989). CONCLUSION Dose-dense adjuvant chemotherapy may be considered the preferred treatment option in high-risk premenopausal breast cancer patients.

Abstract
INTRODUCTION Endocrine therapy is considered the cornerstone treatment for postmenopausal women with hormone-receptor positive metastatic breast cancer. Fulvestrant is a selective estrogen receptor down-regulator (SERD) with demonstrated activity and efficacy in the treatment of these patients. AREAS COVERED The present manuscript aims to review the mechanism of action of fulvestrant, the clinical efficacy data with the use of different dosages and schedules, and finally its role in association with other medications. Expert commentary: Fulvestrant is an active compound with an excellent safety profile for the treatment of women with hormone receptor-positive metastatic breast cancer, The combination of fulvestrant with targeted agents showed increased efficacy and is expected to become a new standard treatment. Results of two clinical trials (i.e. the FALCON and FEVEX trials) are awaited to better clarify the place of fulvestrant in the armamentarium of the available therapies for the treatment of hormone receptor-positive metastatic breast cancer.

Abstract
BACKGROUND Follow-up examinations are commonly performed after primary treatment for women with breast cancer. They are used to detect recurrences at an early (asymptomatic) stage. This is an update of a Cochrane review first published in 2000. OBJECTIVES To assess the effectiveness of different policies of follow-up for distant metastases on mortality, morbidity and quality of life in women treated for stage I, II or III breast cancer. SEARCH METHODS For this 2014 review update, we searched the Cochrane Breast Cancer Group's Specialised Register (4 July 2014), MEDLINE (4 July 2014), Embase (4 July 2014), CENTRAL (2014, Issue 3), the World Health Organization (WHO) International Clinical Trials Registry Platform (4 July 2014) and ClinicalTrials.gov (4 July 2014). References from retrieved articles were also checked. SELECTION CRITERIA All randomised controlled trials (RCTs) assessing the effectiveness of different policies of follow-up after primary treatment were reviewed for inclusion. DATA COLLECTION AND ANALYSIS Two review authors independently assessed trials for eligibility for inclusion in the review and risk of bias. Data were pooled in an individual patient data meta-analysis for the two RCTs testing the effectiveness of different follow-up schemes. Subgroup analyses were conducted by age, tumour size and lymph node status. MAIN RESULTS Since 2000, one new trial has been published; the updated review now includes five RCTs involving 4023 women with breast cancer (clinical stage I, II or III).Two trials involving 2563 women compared follow-up based on clinical visits and mammography with a more intensive scheme including radiological and laboratory tests. After pooling the data, no significant differences in overall survival (hazard ratio (HR) 0.98, 95% confidence interval (CI) 0.84 to 1.15, two studies, 2563 participants, high-quality evidence), or disease-free survival (HR 0.84, 95% CI 0.71 to 1.00, two studies, 2563 participants, low-quality evidence) emerged. No differences in overall survival and disease-free survival emerged in subgroup analyses according to patient age, tumour size and lymph node status before primary treatment. In 1999, 10-year follow-up data became available for one trial of these trials, and no significant differences in overall survival were found. No difference was noted in quality of life measures (one study, 639 participants, high-quality evidence).The new included trial, together with a previously included trial involving 1264 women compared follow-up performed by a hospital-based specialist versus follow-up performed by general practitioners. No significant differences were noted in overall survival (HR 1.07, 95% CI 0.64 to 1.78, one study, 968 participants, moderate-quality evidence), time to detection of recurrence (HR 1.06, 95% CI 0.76 to 1.47, two studies, 1264 participants, moderate-quality evidence), and quality of life (one study, 356 participants, high-quality evidence). Patient satisfaction was greater among patients treated by general practitioners. One RCT involving 196 women compared regularly scheduled follow-up visits versus less frequent visits restricted to the time of mammography. No significant differences emerged in interim use of telephone and frequency of general practitioners's consultations. AUTHORS' CONCLUSIONS This updated review of RCTs conducted almost 20 years ago suggests that follow-up programs based on regular physical examinations and yearly mammography alone are as effective as more intensive approaches based on regular performance of laboratory and instrumental tests in terms of timeliness of recurrence detection, overall survival and quality of life.In two RCTs, follow-up care performed by trained and not trained general practitioners working in an organised practice setting had comparable effectiveness to that delivered by hospital-based specialists in terms of overall survival, recurrence detection, and quality of life.

Abstract
IMPORTANCE Whether the administration of luteinizing hormone-releasing hormone analogues (LHRHa) during chemotherapy is a reliable strategy to preserve ovarian function is controversial owing to both the lack of data on long-term ovarian function and pregnancies and the safety concerns about the potential negative interactions between endocrine therapy and chemotherapy. OBJECTIVE To evaluate long-term results of LHRHa-induced ovarian suppression during breast cancer chemotherapy. DESIGN, SETTING, AND PARTICIPANTS Parallel, randomized, open-label, phase 3 superiority trial conducted at 16 Italian sites. Between October 2003 and January 2008, 281 premenopausal women with stage I to III hormone receptor-positive or hormone receptor-negative breast cancer were enrolled. Last annual follow-up was June 3, 2014. INTERVENTIONS Patients were randomized to receive adjuvant or neoadjuvant chemotherapy alone (control group) or chemotherapy plus triptorelin (LHRHa group). MAIN OUTCOMES AND MEASURES The primary planned end point was incidence of chemotherapy-induced early menopause. Post hoc end points were long-term ovarian function (evaluated by yearly assessment of menstrual activity and defined as resumed by the occurrence of at least 1 menstrual cycle), pregnancies, and disease-free survival (DFS). RESULTS A total of 281 women (median age, 39 [range, 24-45] years) were randomized. Median follow-up was 7.3 years (interquartile range, 6.3-8.2 years). The 5-year cumulative incidence estimate of menstrual resumption was 72.6% (95% CI, 65.7%-80.3%) among the 148 patients in the LHRHa group and 64.0% (95% CI, 56.2%-72.8%) among the 133 patients in the control group (hazard ratio [HR], 1.28 [95% CI, 0.98-1.68]; P = .07; age-adjusted HR, 1.48 [95% CI, 1.12-1.95]; P = .006). Eight pregnancies (5-year cumulative incidence estimate of pregnancy, 2.1% [95% CI, 0.7%-6.3%]) occurred in the LHRHa group and 3 (5-year cumulative incidence estimate of pregnancy, 1.6% [95% CI, 0.4%-6.2%]) in the control group (HR, 2.56 [95% CI, 0.68-9.60]; P = .14; age-adjusted HR, 2.40 [95% CI, 0.62-9.22]; P = .20). Five-year DFS was 80.5% (95% CI, 73.1%-86.1%) in the LHRHa group and 83.7% (95% CI, 76.1%-89.1%) in the control group (LHRHa vs control: HR, 1.17 [95% CI, 0.72-1.92]; P = .52). CONCLUSIONS AND RELEVANCE Among premenopausal women with either hormone receptor-positive or hormone receptor-negative breast cancer, concurrent administration of triptorelin and chemotherapy, compared with chemotherapy alone, was associated with higher long-term probability of ovarian function recovery, without a statistically significant difference in pregnancy rate. There was no statistically significant difference in DFS for women assigned to triptorelin and those assigned to chemotherapy alone, although study power was limited.

Analysis of in vitro ADCC and clinical response to trastuzumab: possible relevance of FcγRIIIA/FcγRIIA gene polymorphisms and HER-2 expression levels on breast cancer cell lines. J Transl Med 2015; 13:324. [PMID: 26450443 PMCID: PMC4598965 DOI: 10.1186/s12967-015-0680-0] [Citation(s) in RCA: 33] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2015] [Accepted: 09/24/2015] [Indexed: 11/10/2022] Open
Abstract
Background Trastuzumab is a humanized monoclonal antibody (mAb) currently used for the treatment of breast cancer (BC) patients with HER-2 overexpressing tumor subtype. Previous data reported the involvement of FcγRIIIA/IIA gene polymorphisms and/or antibody-dependent cellular cytotoxicity (ADCC) in the therapeutic efficacy of trastuzumab, although results on these issues are still controversial. This study was aimed to evaluate in vitro the functional relationships among FcγRIIIA/IIA polymorphisms, ADCC intensity and HER-2 expression on tumor target cells and to correlate them with response to trastuzumab. Patients and methods Twenty-five patients with HER-2 overexpressing BC, receiving trastuzumab in a neoadjuvant (NEO) or metastatic (MTS) setting, were genotyped for the FcγRIIIA 158V>F and FcγRIIA 131H>R polymorphisms by a newly developed pyrosequencing assay and by multiplex Tetra-primer-ARMS PCR, respectively. Trastuzumab-mediated ADCC of patients’ peripheral blood mononuclear cells (PBMCs) was evaluated prior to therapy and measured by 51Chromium release using as targets three human BC cell lines showing different levels of reactivity with trastuzumab. Results We found that the FcγRIIIA 158F and/or the FcγRIIA 131R variants, commonly reported as unfavorable in BC, may actually behave as ADCC favorable genotypes, in both the NEO (P ranging from 0.009 to 0.039 and from 0.007 to 0.047, respectively) and MTS (P ranging from 0.009 to 0.032 and P = 0.034, respectively) patients. The ADCC intensity was affected by different levels of trastuzumab reactivity with BC target cells. In this context, the MCF-7 cell line, showing the lowest reactivity with trastuzumab, resulted the most suitable cell line for evaluating ADCC and response to trastuzumab. Indeed, we found a statistically significant correlation between an increased frequency of patients showing ADCC of MCF-7 and complete response to trastuzumab in the NEO setting (P = 0.006). Conclusions Although this study was performed in a limited number of patients, it would indicate a correlation of FcγR gene polymorphisms to the ADCC extent in combination with the HER-2 expression levels on tumor target cells in BC patients. However, to confirm our findings further experimental evidences obtained from a larger cohort of BC patients are mandatory.

Abstract
105 Background: The PROMISE-GIM6 phase III randomized study showed that the use of triptorelin-induced temporary ovarian suppression during CT in premenopausal patients with early-stage BC reduced the occurrence of CT-induced early menopause (Del Mastro L, JAMA 2011). The 2013 ASCO and ESMO guidelines on fertility preservation in cancer patients consider this strategy still experimental due to the absence of data on long-term ovarian function and pregnancy rates, and some concerns exist on the safety of this procedure particularly for hormone-receptor positive BC patients. The present analysis reports long-term outcome results of the study. Methods: From October 2003 to January 2008, 281 premenopausal women with stage I through III BC who were candidates for adjuvant or neoadjuvant CT were randomized to receive CT alone or combined with triptorelin. The primary objective was to compare the incidence of CT-induced early menopause in patients treated with CT alone or combined with triptorelin. The present analysis considers data on recurrences, pregnancies and long-term ovarian function. Results: A total of 133 pts were enrolled in the CT alone arm and 148 in the CT + LHRHa arm; 82% and 79% of pts had hormone receptor positive-disease, respectively. The median follow-up at the time of the analysis was 7.3 years (interquartile range: 6.3-8.2 years). No differences in the 5-year disease-free survival (DFS) between treatment arms were observed (83.7% in CT alone arm vs 80.5% in CT plus LHRHa: HR=1.17; 95% CI 0.72-1.92, p=0.519). After the end of adjuvant treatments, 4 pregnancies (3.0%; incidence rate per 100 person-year=0.4) occurred in the CT-alone group and 8 pregnancies (5.4%; incidence rate per 100 person-year=0.8) occurred in the CT plus triptorelin group (CT + LHRHa arm vs CT alone: OR=1.84; 95% CI 0.54-6.27, p=0.39). Conclusions: The administration of LHRHa with CT was associated with the occurrence of more pregnancies; no differences in DFS were observed. The analysis on long-term ovarian function is still ongoing and will be presented at the meeting. Clinical trial information: NCT00311636.

Abstract
AIM/BACKGROUND Few data are available about the prevalence of hepatitis B and C infections in early breast cancer patients and its impact on systemic treatments. The objectives of this study were to determine the incidence of positive serology for hepatitis B and C in women with early breast cancer and to assess the clinical course and its impact on liver function during adjuvant treatments. PATIENTS AND METHODS we retrospectively reviewed hepatitis B and C serology [HBs antigen (HBsAg), HBc antibodies (HBcAb), HBs antibodies (HBsAb) and HC (HCV) antibodies] in 746 consecutive patients with early breast cancer treated at our Institution between 2009 and 2011. RESULTS Among 375 evaluable patients, we identified 312 controls (83.2%) and 63 patients (16.8%) with positive serology (cases): 15 patients (4%) with HCV, 8 (2.1%) with resolved HBV without anti-HBs (HBsAg-negative, HBsAgAb-negative, HBcAgAb-positive), 36 (9.6%) with resolved HBV with anti-HBs (HBsAg-negative, HBsAgAb-positive, HBcAgAb-positive) and 4 (1%) with chronic HBV (HBsAg-positive, HBsAgAb-negative, HBcAgAb-positive). During systemic treatments, hepatitis (defined as at least a three-fold increase in serum alanine aminotransferase level) occurred in nine (20.4%) out of 44 evaluable cases and in 14 (5.9%) out of 234 evaluable controls. CONCLUSION Approximately 20% of patients with early breast cancer with positive serology for viral hepatitis may develop hepatitis during systemic treatment. Pre-treatment serum detection of viral hepatitis B and C antigens and antibodies may be useful in the adjuvant therapy decision-making process and for adequate monitoring of liver function during antineoplastic therapy.

Abstract
BACKGROUND Obesity is an independent adverse prognostic factor in early breast cancer patients, but it is still controversial whether obesity may affect adjuvant endocrine therapy efficacy. The aim of our study (ancillary to the two clinical trials Gruppo Italiano Mammella (GIM)4 and GIM5) was to investigate whether the circulating oestrogen levels during treatment with the aromatase inhibitor letrozole are related to body mass index (BMI) in postmenopausal women with breast cancer. METHODS Plasma concentration of oestrone sulphate (ES) was evaluated by radioimmunoassay in 370 patients. Plasma samples were obtained after at least 6 weeks of letrozole therapy (steady-state time). Patients were divided into four groups according to BMI. Differences among the geometric means (by ANOVA and ANCOVA) and correlation (by Spearman's rho) between the ES levels and BMI were assessed. RESULTS Picomolar geometric mean values (95% confidence interval, n=patients) of circulating ES during letrozole were 58.6 (51.0-67.2, n=150) when BMI was <25.0 kg m(-2); 65.6 (57.8-74.6, n=154) when 25.0-29.9 kg m(-2); 59.3 (47.1-74.6, n=50) when 30.0-34.9 kg m(-2); and 43.3 (23.0-81.7, n=16) when ≥35.0 kg m(-2). No statistically significant difference in terms of ES levels among groups and no correlation with BMI were observed. CONCLUSIONS Body mass index does not seem to affect circulating oestrogen levels in letrozole-treated patients.

Abstract
Approximately 6% of women with breast cancer are diagnosed before the age of 40. Young age is an independent predictor of adverse outcome and most young breast cancer patients receive systemic treatment with chemotherapy, hormonal therapy or both. The loss or impairment of fertility is a potential side effect of antineoplastic treatments. Due to the rising trend to delaying pregnancy in life, an increasing proportion of young cancer patients who are yet to have a pregnancy will face the problem of iatrogenic menopause in the future. The incidence of anticancer-treatment-related ovarian failure depends on the type of chemotherapy regimen administered, the use of tamoxifen and the age of patients. It rises with increasing age, in the range of 22-61% and 61-97% in women aged <40 years and >40 years respectively. Although there is a clear trend to increasing incidence of ovarian failure with the rise in aging, there may be a small proportion of patients who became amenorrhoeic despite the very young age, thus indicating that also individual factors still unknown may affect the probability of treatment-related ovarian failure. A prompt referral of patients to reproductive counseling and a multidisciplinary team including Oncology and Reproductive Units are essential to face the management of fertility issues in cancer patients. Fertility counseling should include a detailed description of all the available techniques to preserve fertility. The main available fertility preservation techniques, standard and experimental, for young breast cancer patients include: temporary ovarian suppression during chemotherapy with gonadotropin-releasing hormone analogues, embryo cryopreservation, cryopreservation of oocytes and cryopreservation of ovarian tissue. Research efforts are still necessary to improve the efficacy and safety of the available fertility preservation strategies as well as an efficient collaboration between oncologists and gynecologists is necessary to improve patients' access to the strategies themselves.

Abstract
e17548 Background: Approximately 4.5% of breast cancers are diagnosed in women younger than 40 years. Chemotherapy (CT)-induced loss of fertility is a major concern for young patients. Different strategies are available to attempt to preserve ovarian function. We evaluated feasibility and patient preferences of 3 different strategies: oocyte cryopreservation (OC), ovarian tissue cryopreservation (OTC) and temporary ovarian suppression with the administration of LHRH analogue (LHRHa) during CT. Methods: From March 2010 to January 2013 49 breast cancer patients younger than 45 years (median age: 38 [range 25-45]), referred to our institution. They were offered the possibility to reduce the gonadotoxic effects of anticancer treatments: the oncologist proposed both the administration of LHRHa during CT, and a reproductive counselling performed by the gynecologist, where OC and OTC were discussed. The first analysis was planned after 2 years; preliminary data are presented. Results: The majority of patients (42 [85.7%]) accepted the treatment with LHRHa, started at least 1 week before CT. Thirty-eight patients (77.6%) refused the reproductive counselling; the main reason for refusal was previous pregnancies (19 patients [38.8%]). Out of 11 patients (22.4%) who accepted the reproductive counselling, only 3 (6.1%) accepted to undergo OC and 1 (2.0%) OTC. The reasons for refusal were: not eligible for comorbidities 3 patients [6.1%]), fear of delaying cancer treatment (2 patients [4.1%]), fear of the ovarian stimulation required (1 patients [2.0%]) and low successful rate of the technique (1 patients [2.0%]). The 3 patients undergoing OC received a controlled ovarian stimulation with the use of daily injections of recombinant FSH: median length of stimulation was 9 days (range, 8 to 9 days); peak estradiol levels ranged from 280 to 521 pg/ml. An average of 13.3 ± 5.7 oocytes was retrieved, and 8.3 ± 3.1 oocytes cryopreserved per patient. Conclusions: This preliminary analysis suggests that the majority of patients (85.7%) accept the administration of LHRHa during CT and approximately 8.2% of patients undergoes surgical fertility preservation techniques.

Abstract
1036 Background: In MBC P the benefit of CT after the 1st line (L) is poorly defined. We evaluated activity of subsequent L of CT in different BS of MBC. Methods: MBC P treated in our center from 2007 to 2012 with ER, PgR and HER2 on primary tumor and at least 1 L of CT for MBC were evaluated. P were classified as Luminal A (ER and/or PgR +, HER2 -, Ki67≤14%), Luminal B (ER and/or PgR +, HER2 -, Ki67>14%), HER2+ (HER2+, any ER/PgR) and Triple-Negative ( ER-, PgR- and HER2-). Time on CT was calculated from the start of the 1st L to the end of the last L. Statistical analyses included Chi-square and Kruskal-Wallis tests, Kaplan-Meier curves and log-rank tests, and multivariate logistic regressions. Results: 207 P were identified, 52 were excluded because HER2 was unknown (19) or they did not receive any CT (33). Median follow-up was 31.4 months (m). The median number (N) of CT L was 2 (range 1-10). N of CT L and clinical benefit (CB) for every BS were reported in table. CB was inferior in TN P as compared with the other ones in 1st and in 2nd L ( p=.068 and p=.084 respectively in 1st and 2nd L). From 3rd L onward all P showed the same CB independently from BS. Time on CT related to median survival (S) for every BS was the same. At multivariate analysis the characteristics independently associated with a greater probability of receiving more than 4 CT L were age < 50 years (p=.021), HER2+ or TN disease (p=.027) and site of metastasis other than lung (p=.047). Conclusions: Our analysis showed that, despite the same time spent on CT, TN P received less benefit from 1st and 2nd L CT than other BS. On the other hand, young HER2+ P were more likely to receive multiple L of CT with a significant impact on median S (p=.044). [Table: see text]

Trastuzumab as first-line therapy in HER2-positive metastatic breast cancer patients. Expert Rev Anticancer Ther 2012; 12:1391-405.

Abstract
Trastuzumab is a humanized monoclonal antibody against the extracellular domain of hEGF receptor-2 (HER2). Trastuzumab in combination with chemotherapy has proven efficacy in treating both early and metastatic HER2-positive breast cancer. In the metastatic setting, the addition of trastuzumab to chemotherapy is associated with a statistically significant longer time to disease progression, higher rate of objective response and improvement in overall survival. Trastuzumab efficacy is not influenced by hormone receptor status, but differences in median overall survival exist between HER2-positive and HER2-negative states. Reassessment of the benefit of re-exposing patients with metastatic breast cancer to trastuzumab following relapse in the adjuvant setting is necessary. Ongoing research into new HER2-targeted therapies and trials involving combination anti-HER2 drug therapy without chemotherapy show promise. This review is focused on the available results obtained with the use of trastuzumab in the subset of HER2-positive breast cancer patients with metastatic disease.

Abstract
CONTEXT Premenopausal patients with breast cancer are at high risk of premature ovarian failure induced by systemic treatments, but no standard strategies for preventing this adverse effect are yet available. OBJECTIVE To determine the effect of the temporary ovarian suppression obtained by administering the gonadotropin-releasing hormone analogue triptorelin during chemotherapy on the incidence of early menopause in young patients with breast cancer undergoing adjuvant or neoadjuvant chemotherapy. DESIGN, SETTING, AND PATIENTS The PROMISE-GIM6 (Prevention of Menopause Induced by Chemotherapy: A Study in Early Breast Cancer Patients-Gruppo Italiano Mammella 6) study, a parallel, randomized, open-label, phase 3 superiority trial, was conducted at 16 sites in Italy and enrolled 281 patients between October 2003 and January 2008. The patients were premenopausal women with stage I through III breast cancer who were candidates for adjuvant or neoadjuvant chemotherapy. Assuming a 60% rate of early menopause in the group treated with chemotherapy alone, it was estimated that 280 patients had to be enrolled to detect a 20% absolute reduction in early menopause in the group treated with chemotherapy plus triptorelin. The intention-to-treat analysis was performed by including all randomized patients and using imputed values for missing data. INTERVENTIONS Before beginning chemotherapy, patients were randomly allocated to receive chemotherapy alone or combined with triptorelin. Triptorelin was administered intramuscularly at a dose of 3.75 mg at least 1 week before the start of chemotherapy and then every 4 weeks for the duration of chemotherapy. MAIN OUTCOME MEASURE Incidence of early menopause (defined as no resumption of menstrual activity and postmenopausal levels of follicle-stimulating hormone and estradiol 1 year after the last cycle of chemotherapy). RESULTS The clinical and tumor characteristics of the 133 patients randomized to chemotherapy alone and the 148 patients randomized to chemotherapy plus triptorelin were similar. Twelve months after the last cycle of chemotherapy (last follow-up, August 18, 2009), the rate of early menopause was 25.9% in the chemotherapy-alone group and 8.9% in the chemotherapy plus triptorelin group, an absolute difference of -17% (95% confidence interval, -26% to -7.9%; P < .001). The odds ratio for treatment-related early menopause was 0.28 (95% confidence interval, 0.14 to 0.59; P < .001). CONCLUSION The use of triptorelin-induced temporary ovarian suppression during chemotherapy in premenopausal patients with early-stage breast cancer reduced the occurrence of chemotherapy-induced early menopause.

Accuracy of sentinel lymph node biopsy after neo-adjuvant chemotherapy in patients with locally advanced breast cancer and clinically positive axillary nodes. Eur J Surg Oncol 2011; 37:688-94.

Abstract
BACKGROUND Feasibility and accuracy of sentinel node biopsy (SLNB) after the delivery of neo-adjuvant chemotherapy (NAC) is controversial. We here report our experience in NAC-treated patients with locally advanced breast cancer and clinically positive axillary nodes, and compare it with the results from our previous randomized trial assessing SLNB in early-stage breast cancer patients. PATIENTS AND METHODS Sixty-four consecutive patients with large infiltrating tumor and clinically positive axillary nodes received NAC and subsequent lymphatic mapping, SLNB and complete axillary lymph node dissection (ALND). The status of the sentinel lymph node (SLN) was compared to that of the axilla. RESULTS At least one SLN was identified in 60 of the 64 patients (93.8%). Among those 60 patients, 37 (61.7%) had one or more positive SLN(s) and 23 (38.3%) did not. Two of the patients with negative SLN(s) presented metastases in other non-sentinel nodes. SLNB thus had a false-negative rate, a negative predictive value and an overall accuracy of 5.1%, 91.3% and 96.7%, respectively. All these values were similar to those we reported for SLNB in the settings of early-stage breast cancer. CONCLUSION SLNB after NAC is safe and feasible in patients with locally advanced breast cancer and clinically positive nodes, and accurately predicts the status of the axilla.

Abstract
Abstract
Background: There is strong evidence that VEGF plays an important role in the pathogenesis and progression of human breast cancer. Bevacizumab, a monoclonal antibody, specifically inhibits VEGF. The combination of first-line bevacizumab with chemotherapy significantly improved the activity in comparison to chemotherapy alone in three randomized phase III trials in metastatic breast cancer patients (pts). In early breast cancer, the FEC→Paclitaxel regimen is a highly active standard therapy. Therefore we initiated a trial to evaluate the combination of bevacizumab with this efficacious chemotherapy regimen for the treatment of stage III or inflammatory early breast cancer (LABC).
Patients and Methods: The study is designed to evaluate a sequential regimen of FEC90 followed by the combination of paclitaxel and bevacizumab as neoadjuvant therapy in patients with HER2-negative locally advanced (stage III or inflammatory) breast cancer. Patients are treated with neoadjuvant FEC 600/90/600 mg/m2 q21d x 4, followed by paclitaxel 80 mg/m2 weekly x 12 combined with bevacizumab 10 mg/kg q2w x 6. Patients undergo surgery 4 weeks after completing chemotherapy. Pathologic complete response (pCR), the primary endpoint, is defined as no evidence of invasive tumor in the final surgical sample both in the breast and axilla. Secondary endpoints include objective clinical response rate (RR), disease-free interval, overall survival, rate of breast-conserving surgery, and the safety of the regimen.
Results: Between Feb 2008 and Dec 2009, 54 pts (mean age of 51±7.5 years) were enrolled into the study. To date, 32 pts have completed neoadjuvant treatment and surgery and are evaluable for response. Baseline characteristics in these 32 patients were as follows: cT3/cT4b: 20 (63%) and/or cN2/cN3: 14 (43%); estrogen receptor (ER) positive: 24 (75%) and 8 (25%) triple-negative (TN), defined as ER negative, progesterone receptor-(PgR-) negative, and HER2 negative. Histological type was ductal carcinoma in 24 patients (75%), lobular carcinoma in 4 (13%), inflammatory breast cancer in 1 (3%), and other in 3 (9%). Mastectomy was performed in 22 patients (69%) and breast-conserving surgery in 10 patients (31%). After neoadjuvant treatment, 8/32 patients (25%) achieved a pCR.
Conclusions: This open-label, multicenter, phase II study demonstrated that the FEC→Paclitaxel plus bevacizumab combination is a highly active neoadjuvant treatment for HER2-negative locally advanced breast cancer. A 25% of pCR in this group of pts with high tumor burden, i.e. the LABC, is oneof the most promising chemotherapeutic regimen if confirmed in the final analyis. Results for all 54 pts enrolled will be presented at the meeting.
