Randomized phase II study of fulvestrant plus palbociclib or placebo in endocrine-sensitive, hormone receptor-positive/HER2-advanced breast cancer: GEICAM/2014-12 (FLIPPER).

BACKGROUND: The potential benefit of adding palbociclib to fulvestrant as first-line treatment in hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative endocrine-sensitive advanced breast cancer (ABC) patients remains uncharacterized. PATIENTS AND METHODS: In this randomized (1:1), double-blind, phase II study, postmenopausal women with HR-positive, HER2-negative ABC with de novo metastatic disease or those who relapsed after >12 months of adjuvant endocrine therapy received palbociclib/fulvestrant or placebo/fulvestrant. Stratification was based on recurrent versus de novo metastatic disease and visceral involvement. The primary objective was one-year progression-free survival (PFS-1y) rate. The sample size was 190 patients. The two-sided alpha of 0.2, 80% of power to detect a difference between the arms, assuming PFS rates of 0.695 and 0.545 for palbociclib/fulvestrant and placebo/fulvestrant, respectively. RESULTS: In total, 189 patients were randomized to palbociclib/fulvestrant ([n = 94] or placebo/fulvestrant [n = 95]). 45.5% and 60.3% of patients had de novo metastatic disease and visceral involvement, respectively. PFS-1y rates were 83.5% and 71.9% in the palbociclib/fulvestrant and placebo/fulvestrant arms, (HR 0.55, 80% CI 0.36-0.83, P = 0.064). The median PFS were 31.8 and 22.0 months for the palbociclib/fulvestrant and placebo/fulvestrant arms (aHR 0.48, 80% CI 0.37-0.64, P = 0.001). The most frequent grade 3-4 adverse events were neutropenia (68.1% vs. 0%), leucopenia (26.6% vs. 0%), anemia (3.2% vs. 0%), and lymphopenia (14.9% vs. 2.1%) for the palbociclib/fulvestrant and placebo/fulvestrant, respectively. The most frequent non-hematologic grade 3-4 adverse event was fatigue (4.3% vs. 0%). CONCLUSIONS: Palbociclib/fulvestrant demonstrated better PFS-1y rates and median PFS than placebo/fulvestrant in HR-positive/HER2-negative endocrine-sensitive ABC patients.

Palbociclib in combination with endocrine therapy versus capecitabine in hormonal receptor-positive, human epidermal growth factor 2-negative, aromatase inhibitor-resistant metastatic breast cancer: a phase III randomised controlled trial-PEARL.

BACKGROUND: Palbociclib plus endocrine therapy (ET) is the standard treatment of hormone receptor-positive and human epidermal growth factor receptor 2-negative, metastatic breast cancer (MBC). However, its efficacy has not been compared with that of chemotherapy in a phase III trial. PATIENTS AND METHODS: PEARL is a multicentre, phase III randomised study in which patients with aromatase inhibitor (AI)-resistant MBC were included in two consecutive cohorts. In cohort 1, patients were randomised 1 : 1 to palbociclib plus exemestane or capecitabine. On discovering new evidence about estrogen receptor-1 (ESR1) mutations inducing resistance to AIs, the trial was amended to include cohort 2, in which patients were randomised 1 : 1 between palbociclib plus fulvestrant and capecitabine. The stratification criteria were disease site, prior sensitivity to ET, prior chemotherapy for MBC, and country of origin. Co-primary endpoints were progression-free survival (PFS) in cohort 2 and in wild-type ESR1 patients (cohort 1 + cohort 2). ESR1 hotspot mutations were analysed in baseline circulating tumour DNA. RESULTS: From March 2014 to July 2018, 296 and 305 patients were included in cohort 1 and cohort 2, respectively. Palbociclib plus ET was not superior to capecitabine in both cohort 2 [median PFS: 7.5 versus 10.0 months; adjusted hazard ratio (aHR): 1.13; 95% confidence interval (CI): 0.85-1.50] and wild-type ESR1 patients (median PFS: 8.0 versus 10.6 months; aHR: 1.11; 95% CI: 0.87-1.41). The most frequent grade 3-4 toxicities with palbociclib plus exemestane, palbociclib plus fulvestrant and capecitabine, respectively, were neutropenia (57.4%, 55.7% and 5.5%), hand/foot syndrome (0%, 0% and 23.5%), and diarrhoea (1.3%, 1.3% and 7.6%). Palbociclib plus ET offered better quality of life (aHR for time to deterioration of global health status: 0.67; 95% CI: 0.53-0.85). CONCLUSIONS: There was no statistical superiority of palbociclib plus ET over capecitabine with respect to PFS in MBC patients resistant to AIs. Palbociclib plus ET showed a better safety profile and improved quality of life.

BOMET-QoL-10 questionnaire for breast cancer patients with bone metastasis: the prospective MABOMET GEICAM study.

BACKGROUND: Bone metastasis (BM) is the most common site of disease in metastatic breast cancer (MBC) patients. BM impacts health-related quality of life (HRQoL). We tested prospectively the psychometric properties of the Bone Metastasis Quality of Life (BOMET-QoL-10) measure on MBC patients with BM. METHODS: Patients completed the BOMET-QoL-10 questionnaire, the Visual Analogue Scale (VAS) for pain, and a self-perceived health status item at baseline and at follow-up visits. We performed psychometric tests and calculated the effect size of specific BM treatment on patients´ HRQoL. RESULTS: Almost 70% of the 172 patients reported symptoms, 23.3% experienced irruptive pain, and over half were receiving chemotherapy. BOMET-QoL-10 proved to be a quick assessment tool performing well in readability and completion time (about 10 min) with 0-1.2% of missing/invalid data. Although BOMET-QoL-10 scores remained fairly stable during study visits, differences were observed for patient subgroups (e.g., with or without skeletal-related events or adverse effects). Scores were significantly correlated with physician-reported patient status, patient-reported pain, symptoms, and perceived health status. BOMET-QoL-10 scores also varied prospectively according to changes in pain intensity. CONCLUSIONS: BOMET-QoL-10 performed well as a brief, easy-to-administer, useful, and sensitive HRQoL measure for potential use for clinical practice with MBC patients. TRIAL REGISTRATION: NCT03847220. Retrospectively registered on clinicaltrials.gov (February the 20th 2019).

Changes in dietary intake, plasma carotenoids and erythrocyte membrane fatty acids in breast cancer survivors after a lifestyle intervention: results from a single-arm trial.

BACKGROUND: The influence of nutrition on breast cancer prognosis is still inconclusive and therefore dietary interventions incorporating dietary biomarkers are needed to confirm compliance with dietary goals and clarify biological mechanisms. The present study assessed whether a lifestyle intervention in breast cancer survivors could affect dietary biomarkers of fruit and vegetables and fatty acids. METHODS: In this phase II single-arm trial, 37 overweight/obese early stage breast cancer patients completed a 12-week diet and exercise intervention. The intervention involved 1-h weekly diet sessions delivered by a dietician and 75-min bi-weekly physical activity sessions of moderate-to-high intensity led by trained monitors. Before and after the intervention, three 24-h dietary recalls were carried out to calculate nutrient intakes and, in addition, blood samples were taken to measure plasma carotenoids, vitamin E and retinol concentrations and erythrocyte membrane fatty acid (EFA) composition. Wilcoxon signed rank tests were used to assess changes in dietary and biomarkers measurements over the intervention period. RESULTS: After the intervention, there was a significant increase in the intake of dietary carotenoids (+15.1% compared to baseline) but not plasma carotenoids levels (+6.3%). Regarding the EFA levels, we observed a significant decrease in percentage of saturated fatty acids (-1.4%) and n-6 polyunsaturated fatty acids (-2.9%) and an increase in monounsaturated fatty acids (1.7%) and total and long-chain n-3 polyunsaturated fatty acids (by 13.1% and 13.7%, respectively). A favourable decrease in the ratio of long-chain n-6 to n-3 polyunsaturated fatty acids (-9.1%) was also observed. CONCLUSIONS: After a short-term diet and exercise intervention in overweight/obese breast cancer survivors, we observed significant changes in dietary nutrients and fatty acid biomarkers, suggesting positive dietary changes that could be relevant for breast cancer prognosis.

SEOM clinical guidelines in early stage breast cancer (2018)

Breast cancer is the most common cancer in women in our country and it is usually diagnosed in the early and potentially curable stages. Nevertheless, around 20-30% of patients will relapse despite appropriate locoregional and systemic therapies. A better knowledge of this disease is improving our ability to select the most appropriate therapy for each patient with a recent diagnosis of an early stage breast cancer, minimizing unnecessary toxicities and improving long-term efficacy

Real-world data on the efficacy and safety of weekly oral vinorelbine in breast cancer patients previously treated with anthracycline or taxane-based regimens.

PURPOSE: To evaluate the efficacy and safety of oral weekly vinorelbine 60 mg/m2 for metastatic breast cancer (MBC) in patients previously treated with anthracyclines or taxanes in routine clinical practice. MATERIALS AND METHODS: Fifty-five patients were enrolled in a prospective multicentre study conducted in Spain. Women ≥ 18 years of age with locally advanced breast cancer who were not candidates for surgical treatment with a radical intention or patients with stage IV disease, and who had received a prior taxane or anthracycline regimen were eligible for participation. RESULTS: Median age was 67 years. Median progression-free survival was 3.7 months (95% CI 2.5-4.9), median overall survival 10 months (95% CI 6.6-13.5), and overall response rate and clinical benefit rate were 29.1% and 49.1%, respectively. Main grade 3 and 4 toxicities were neutropenia 9.1%, febrile neutropenia 3.6% and constipation 3.6%. In total, 86% of the patients received complete treatment without delays or dose reduction. Moreover, HER2-positive patients who received oral vinorelbine concomitantly with trastuzumab showed better response (complete response: HER2-positive 14.3% vs. HER2-negative 0%; partial response: HER2-positive 42.9% vs. HER2-negative 25.6%; p = 0.008), better disease control rate (HER2-positive 100% vs. HER2-negative 46.2%; p = 0.011), and better values for the remaining analysed variables than HER2-negative patients. CONCLUSION: Our study provides real-world data on the use of oral weekly vinorelbine, which proves an effective and well-tolerated regimen for MBC patients previously treated with taxanes or anthracyclines. Patients with HER2-positive disease could also benefit from this treatment in combination with trastuzumab.

Identification of oestrogen, progesterone receptor and human epidermal growth factor receptor 2 expression in mediastinal metastases of breast cancer obtained by endobronchial ultrasound-guided transbronchial needle aspiration.

BACKGROUND: In breast cancer patients, the expression statuses of oestrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2) are crucial in the choice of treatment. Receptor expression in metastatic lesions can differ from the primary tumour. The aim of our study was to analyse the utility of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) to obtain samples allowing the identification of ER, PR and HER2 expression in patients with mediastinal metastases of breast cancer. PATIENTS AND METHODS: The clinical files of all patients with a final diagnosis of breast cancer mediastinal metastases diagnosed by EBUS-TBNA in our institution were retrospectively analysed. The ability of EBUS-TBNA to obtain samples that allowed hormone receptor and HER2 expression analysis was calculated. RESULTS: Twenty-four patients were included. ER, PR and HER2 assessments could be performed in 22, 20 and 22 patients, respectively. In 20 of the 24 patients it was possible to investigate all three types of receptor expression. In the remaining four cases, where ER, PR or HER2 expression tests could not be performed, it was due to a lack of tissue. In cases with adequate results for EBUS-TBNA and the primary tumour agreement was greater for ER (16/19) and HER2 (12/14) than PR (8/17). Based on receptor status, there was a change in the choice of treatment for five patients. CONCLUSION: In patients with breast cancer mediastinal metastases, ER, PR and HER2 expression can be assessed in samples obtained by EBUS-TBNA whenever a sufficient tissue sample is collected.

DNA repair pathways to regulate response to chemoradiotherapy in patients with locally advanced head and neck cancer.

Platinum-based chemoradiotherapy (CRT) is a preferred standard of care for locally advanced head and neck cancer (HNC). However, survival benefit is small, with substantial toxicity and biomarkers of CRT resistance that could guide treatment selection and spare morbidity. Increased DNA repair in solid tumors may contribute to cancer cells' ability to survive in genotoxic stress environments afforded by therapy. We assessed mRNA expression levels of DNA repair-related genes BRCA1, RAP80, 53 binding protein 1 (53BP1), mediator of DNA damage checkpoint 1 (MDC1), and RNF8. We correlated our findings with response and overall survival in 72 head and neck patients treated with weekly carboplatin AUC 2 and radiotherapy. Complete response (CR) to CRT was 50 % in patients with low levels of 53BP1 compared to 6.3 % in patients with high levels (p = 0.0059). Of high BRCA1 mRNA expressors, 41.2 % had CR compared to 29.4 % of low expressors (p = 0.72). For a small group of patients with low 53BP1 and either high BRCA1 or RAP80, CRs were 66.7 and 71.4 %, respectively. A trend for better overall survival (OS) was found for patients with low 53BP1 (15 vs 8 m; p = 0.056). Our findings highlight the potential usefulness of 53BP1 mRNA as a predictive biomarker of response and overall survival in HNC patients treated with chemoradiotherapy. Those with high 53BP1 expression could derive only a meager benefit from treatment. Analysis of BRCA1 and RAP80 could further reinforce the predictive value of 53BP1. Although this was a retrospective study with small sample size, it could inform larger translational studies in HNC.

Prognostic factors for relapse in stage I seminoma: a new nomogram derived from three consecutive, risk-adapted studies from the Spanish Germ Cell Cancer Group (SGCCG).

BACKGROUND: We aimed to analyze prognostic factors for relapse in stage I seminoma managed by either active surveillance or adjuvant chemotherapy, and to describe the long-term patterns of recurrence in both groups. PATIENTS AND METHODS: From 1994 to 2008, 744 patients were included in three consecutive, prospective risk-adapted studies by the Spanish Germ Cell Cancer Group. Low-risk patients were managed by surveillance and high-risk patients were given two courses of adjuvant carboplatin. Relapses were treated mainly with chemotherapy. Patient age, tumor size, histological variant, pT staging, rete testis invasion, and preoperative serum BHCG levels were assessed for prediction of disease-free survival (DFS). RESULTS: After a median follow-up of 80 months, 63 patients (11.1%) have relapsed: 51/396 (14.8%) on surveillance and 12/348 (3.2%) following adjuvant carboplatin. Actuarial overall 5-year DFS was 92.3% (88.3% for surveillance versus 96.8% for chemotherapy, P = 0.0001). Median time to relapse was 14 months. Most recurrences were located at retroperitoneum (86%), with a median tumor size of 26 mm. All patients were rendered disease-free with chemotherapy (92%), radiotherapy (5%), or surgery followed by chemotherapy (3%). A nomogram was developed from surveillance patients that includes two independent, predictive factors for relapse: rete testis invasion and tumor size (as a continuous variable). CONCLUSION: Long-term follow-up confirms the risk-adapted approach as an effective option for patients with stage I seminoma. The pattern of relapses after adjuvant chemotherapy is similar to that observed following surveillance. A new nomogram for prediction of DFS among patients on surveillance is proposed. Rete testis invasion and tumor size should be taken into account when considering the administration of adjuvant carboplatin. Prospective validation is warranted.

Prescription refill, patient self-report and physician report in assessing adherence to oral endocrine therapy in early breast cancer patients: a retrospective cohort study in Catalonia, Spain.

AIMS: To compare different methods in order to assess adherence and persistence with oral endocrine therapy in women diagnosed with breast cancer (BC) in Catalonia. MATERIALS AND METHODS: This study covered all women newly diagnosed with stage I, II or IIIa BC and positive hormone receptors at six hospitals in Catalonia (Spain) in 2004. Adherence was assessed on the basis of physician report and patient self-report using a telephone questionnaire. Persistence was measured by refill prescriptions. We used the Kappa index to compare adherence measures and logistic regression to evaluate adherence-related risk factors. RESULTS: The study covered a total of 692 women. Adherence ranged from 92% (self-report) to 94.7% (physician report), depending on the measure used; persistence was 74.7% at 5 years of follow-up. Low concordance between measures was observed (Kappa range: 0.018-0.267). Patients aged 50-74 years showed higher adherence than those aged <50 years. Adherence was also associated with: adjuvant chemotherapy and sequential hormonal therapy. CONCLUSIONS: Concordance between the different measures was remarkably low, indicating the need for further research. Adherence is an issue in the management of BC patients taking oral drugs, and should be assessed in clinical practice.

Cáncer oculto de la mama. Caso clínico y revisión de la literatura / Occult breast cancer. Case report and literature review

Se presenta el caso clínico de una paciente con un cáncer oculto de la mama. La situación clínica en la que se detectan ganglios axilares afectos por metástasis de adenocarcinoma pero sin evidenciarse tumor en la mama no es frecuente: entre el 0,3 y 0,8% de todos los tumores de la mama. En esta revisión se subraya la importancia que está adquiriendo el PET como técnica de elección en la detección del tumor primario así como en la monitorización de la respuesta a la quimioterapia neoadyuvante. Asimismo, se repasan los diferentes y controvertidos tratamientos propuestos. La tendencia actual es de máxima conservación, preconizando la disección axilar con radioterapia y tratamiento sistémico posteriores. En este último adquiere especial importancia el análisis inmunohistoquímico de la metástasis ganglionar para un diseño adecuado de la quimioterapia y los agentes anti-diana (AU)

We report the case of a patient with occult cancer of the breast. A finding of metastatic adenocarcinoma to the axillary nodes with no apparent mass in the breast is rare, occurring in 0.3% to 0.8% of all breast tumors. This review of the literature highlights the importance of positron emission tomography, which is becoming the gold standard in the detection of primary tumors and in monitoring response to neoadjuvant chemotherapy. The various treatments proposed and their controversies are also discussed. The current trend is breast conservation. Axillary dissection, adjuvant radiotherapy and systemic treatment are recommended. In the latter, immunohistochemical analysis of lymph node metastases is particularly important for the appropriate design of chemotherapy and anti-target agents (AU)

Phase I/II docetaxel plus concurrent hyperfractionated radiotherapy in locally advanced unresectable head and neck cancer (TAX. ES1. 102 study)

INTRODUCTION: Concurrent chemotherapy and radiotherapy is recommended for the treatment of locally advanced unresectable head and neck (H&N) cancer. OBJECTIVE: The primary purpose of the Phase I part of the study was to determine the maximum tolerated dose (MTD), dose-limiting toxicity (DLT) and recommended dose (RD) of docetaxel with hyperfractionation radiotherapy. The primary objective of the Phase II part was to determine the response rate to the RD of treatment and, secondarily, to assess the toxicity of the schedule, time to progression, duration of response and overall survival (OS). MATERIALS AND METHODS: Patients (n=9 in Phase I; n=19 in Phase II) had unresectable H&N cancer. The starting docetaxel dose was 20 mg/m(2) plus hyperfractionated radiotherapy. Ramping of docetaxel was 5 mg/m(2) if MTD was not reached. RESULTS: MTD of docetaxel was 20 mg/m(2). Limiting toxicities were grade 4 pneumonia and grade 4 mucositis. The RD was 15 mg/m(2). Phase II initial response was 76% (CR=18%; PR=9%); updated response was 89% (CR=59%; PR=29%). The median progression-free survival was 7.8 months (95%CI: 0-22.3) and the median OS was 15.1 months (95%CI: 0-35.9). Grade 3-4 toxicities included mucositis (91%), pneumonia (27%) and fatigue (27%). There were 5 toxic deaths (2 from intestinal perforation, 3 from pneumonia). CONCLUSIONS: Weekly docetaxel+hyperfractionation radiotherapy is active but with high toxicity rates and, hence, this treatment regimen would be difficult to justify (AU)

Biweekly vinorelbine and tegafur/uracil in patients with metastatic breast cancer previously treated with anthracyclines and taxanes: GEICAM 2000-02 phase II study

INTRODUCTION: To assess the efficacy and safety profile of biweekly vinorelbine and tegafur/uracil (UFT) as treatment in patients with metastatic breast cancer previously treated with anthracyclines and taxanes. PATIENTS AND METHODS: Patients with histologically confirmed breast cancer, measurable disease, no more than one prior chemotherapy regimen for metastatic disease, an Eastern Cooperative Oncology Group (ECOG) performance status ≤2, and adequate bone marrow, renal and liver function were eligible. Patients received vinorelbine (30 mg/m(2) on day 1) and UFT (250 mg/m(2) daily) every two weeks for 12 cycles unless progression or unacceptable toxicity was observed. RESULTS: Thirty-seven patients were included and received 311 cycles of chemotherapy. Efficacy and toxicity analyses were carried out on an intention-to-treat basis. The overall response rate was 35% (95% CI: 20-53). With a median follow-up of 18.6 months (95% CI: 1.0-74.3), the median time to progression was 7.0 months (96% CI: 5.2-8.9) and the median overall survival was 19.4 months (95% CI: 11.1-27.8). The most common severe toxicities were neutropenia (38% of patients) and asthenia (11% of patients). CONCLUSION: The combination of biweekly vinorelbine and UFT in patients with metastatic breast cancer pretreated with anthracyclines and taxanes is a well tolerated and effective regimen.

Pegylated liposomal doxorubicin in combination with cyclophosphamide and trastuzumab in HER2-positive metastatic breast cancer patients: efficacy and cardiac safety from the GEICAM/2004-05 study.

BACKGROUND: In order to determine the feasibility of substituting pegylated liposomal doxorubicin (PLD) for doxorubicin in combination with cyclophosphamide and trastuzumab as adjuvant therapy, we conducted a phase II study of the combination as first-line therapy in human epidermal growth factor receptor 2 (HER2) overexpressing metastatic breast cancer (MBC). METHODS: PLD 50 mg/m(2) and cyclophosphamide 600 mg/m(2) were administered every 4 weeks for six cycles; trastuzumab (4 mg/kg loading dose, then 2 mg/kg) was administered weekly for 24 weeks. The primary end point was objective response rate (ORR), and the secondary end points included time to progression (TTP), overall survival (OS), and safety. RESULTS: Among the 48 evaluable patients, ORR was 68.8% [95% confidence interval (CI) 55.69% to 81.91%], with 6 patients (12.5%) achieving a complete response and 27 (56.2%) a partial response. The median TTP was 12 months (95% CI 9-15.1 months), and the median OS was 34.2 months (95% CI 27.2-41.2 months). Febrile neutropenia was seen in three patients, grade 3 hand-foot syndrome in 29.2% of patients, and grade 3-4 mucositis in 22.9% of patients. Symptomatic congestive heart failure was not observed, and 16.7% of patients experienced grade 2 asymptomatic left ventricular systolic dysfunction. CONCLUSION: The combination of PLD-cyclophosphamide-concurrent trastuzumab is a feasible, safe, and effective first-line regimen for HER2-overexpressing MBC.

Information and communication technology systems to improve quality of life and safety of Alzheimer's disease patients: a multicenter international survey.

Within the frame of the European Commission funded Smart Home for Elderly People (HOPE) Project, relatives/caregivers of 223 Alzheimer's Disease (AD) patients were recruited in Italy, Spain, and Greece for a multicenter international survey on the potential role of Information and Communication Technology system (ICT-systems) for AD patients. A five-minute video on HOPE ICT-systems was shown, and all relatives/caregivers completed a 13-item questionnaire that evaluated the potential role of: A) ICT-systems in improving quality of life, care, and safety; B) devices for monitoring personal movements, medication use, and ambient environmental conditions; C) devices to improve communication, home-based rehabilitation, and reduction of specific risks; and D) possible agreement in using ICT-systems by AD patients. Relatives/caregivers reported that ICT-systems could be very useful to improve: A) quality of life (66.4%), care (56.1%), and safety (87.0%); B) monitoring bed rest and movements (80.7%), medication use (87.4%), and ambient environmental conditions (85.2%); and C) emergency communication (83.4%). Relatives/caregivers reported that ICT-systems could be significantly more useful for AD patients aged 75-84 than patients aged <75 or ≥85 years (p < 0.0001) and with moderate than mild or severe dementia (p < 0.0001). Relatives/caregivers aged ≥50 years and with low educational level considered ICT-systems more useful than relatives/caregivers aged <50 years (p < 0.0001) and with high educational level (p < 0.0001). In conclusion, relatives/caregivers considered that the HOPE ICT-system could be useful to improve the management of AD patients.

Monitorización de la respuesta a la terapia neoadyuvante en el carcinoma de mama localmente avanzado mediante métodos de imagen / No disponible

Objetivo: Establecer la validez diagnóstica de la mamografía, de la resonancia magnética y de la gammagrafía 99mTc-sestamibi en la valoración de la respuesta terapéutica de pacientes diagnosticadas de carcinoma de mama localmente avanzado. Pacientes y métodos: Estudio prospectivo observacional aprobado por el Comité Ético de nuestra institución en el que se han incluido 75 pacientes diagnosticadas de carcinoma de mama localmente avanzado por core biopsia (edad media: 52 años, rango: 26-80 años). Las pacientes fueron valoradas clínicamente, por mamografía, resonancia magnética y gammagrafía 99mTc-sestamibi antes de iniciar la terapia neoadyuvante y una vez finalizada la misma. Se han administrado regímenes terapéuticos basados en antraciclinas excepto en siete pacientes que recibieron hormonoterapia con inhibidores de la aromatasa. Para la valoración de la respuesta clínica se utilizaron los criterios RECIST y los mismos criterios, adaptados y consensuados, se emplearon para la valoración de la respuesta mediante técnicas de imagen e histología. Resultados: Tras cirugía se constató respuesta histológica, bien sea parcial o completa, en 61 pacientes (81,3%). Se evidenció conformidad entre la respuesta clínica y los hallazgos histológicos en el 80% de los casos, entre mamografía e histología en el 79,7% de casos, y esta fue del 78,9 % para la resonancia magnética y del 86,4% para la gammagrafía. La sensibilidad y especificidad fueron del 64,3 y del 83,8% para la mamografía, del 61,5 y 82,8% para la resonancia magnética, y del 58,3 y 92,6%, para la gammagrafía. Se pudo observar una concordancia del 88,8% entre resonancia y gammagrafía, del 75,7% entre esta y la mamografía y del 77,3 % entre gammagrafía y mamografía. Conclusiones: La resonancia magnética y la gammagrafía 99mTc-sestamibi demuestran su utilidad en la valoración de la respuesta tras la terapia neoadyuvante, si bien persiste la dificultad en la valoración de focos microscópicos de tumor o del componente in situ, y por tanto, en la definición de respuesta completa(AU)

Aim: To establish diagnostic validity of mammography, mammary magnetic resonance and 99mTc-sestamibi scintimammography to assess response to neoadjuvant therapy in patients with locally advanced breast cancer. Patients and methods: A prospective observational study was approved at our institution which included 75 women with core biopsy diagnostic of locally advanced breast cancer (mean age: 52 y, range 26-80 y). All patients had clinical, mammography, mammary magnetic resonance and 99mTc-sestamibi scintimammography assessment before and after receiving neoadjuvant therapy. Primary chemotherapy based on anthracyclines was administered except in seven patients who received endocrine therapy with aromatase inhibitors. RECIST criteria were considered for clinical response assessment, and the same criteria were adapted for imaging methods and pathologic response. Results: After surgery, 61 patients (81,3%) showed histologic response (complete or partial). Clinical assessment of tumour response was in concordance with histologic study in 80% of patients. Mammography, magnetic resonance and scintimammography agreed with pathology in 79,7, 78,9 and 86,4% of patients, respectively. Based on histologic response, sensitivity and specificity were 64,3 and 83,8% for mammography, 61,5 and 82,8% for magnetic resonance, and 58,3 and 92,6% for scintimammography, respectively. Agreement between magnetic resonance and scintimammography was 88,8%, between magnetic resonance and mammography 75,7%, and 77,3% between scintimammography and mammography. Conclusion: Magnetic resonance and scintimammography should be added to the diagnostic arsenal since they have shown more reliability than conventional methods for predicting histopathologic response to neoadjuvant therapy. Nevertheless, tumour size is critical for the detection of residual small lesions, usually microscopic and DCIS foci, or in others words, there is a limitation to define complete response(AU)
