Arthralgia and myalgia associated with aromatase inhibitors: frequency and characterization in real-life patients.

Introduction: Adjuvant treatment with aromatase inhibitors (AI) in oestrogen receptor-positive and/or progesterone receptor-positive breast cancer (BC) has been shown to increase overall survival. However, arthralgias and myalgias are common adverse effects in patients treated with AI. Objective: To evaluate the frequency and characteristics of arthralgias and myalgias in patients with early BC-treated adjuvantly with AI in the Mastology Unit of the Oncology Service of the Hospital de Clínicas and the Departmental Hospital of Soriano. Materials and methods: A prospective, cross-sectional and descriptive study was performed. A questionnaire was administered to patients to assess the presence and characteristics of arthralgias and myalgias associated with AI. Statistical analysis: 'Age' was described with measures of central tendency and dispersion. Qualitative variables were presented in absolute and relative frequencies. Logistic models were used to evaluate the association between patient characteristics, tumour characteristics, treatment characteristics and the presence of pain. Results were presented by odds ratio and p-value, using R software (version 4.1.2) with a significance threshold of 5%. Results: 83 patients were included, with a median age of 69 years. 75.9% presented arthralgias and/or myalgias related to treatment, with an average intensity of 5-7. 80.9% received non-steroidal anti-inflammatory drugs (NSAIDs), achieving satisfactory analgesia. The presence of arthralgias and myalgias was significantly associated with age and time since the last menstrual period (LMP), being more frequent in patients older than 50 years and those with more than 5 years since the LMP. Conclusion: Approximately 70% of the patients presented arthralgias or myalgias. These findings suggest a possible role of oestrogen withdrawal in its mechanism of development. Multidisciplinary and translational research is crucial to evaluate the ethology and therapeutic options for patients with AI-related arthralgia.

Efficacy of First-Line Treatment With Pertuzumab and Trastuzumab in Advanced Human Epidermal Growth Factor Receptor 2-Positive Breast Cancer in Routine Clinical Practice.

Background: The first-line treatment for human epidermal growth factor receptor 2-positive (HER2+) metastatic breast cancer (MBC) involves a combination of trastuzumab, pertuzumab, and a taxane (TPH). This study assessed the efficacy of trastuzumab and pertuzumab (PH) in routine practice, following the treatment protocols of Uruguay's National Resources Fund (FNR), akin to clinical trials. Methods: Patients with advanced MBC treated with PH between 2008 and 2022 per FNR protocols were evaluated. The Kaplan-Meyer method and log-rank test were utilized for analyzing overall survival (OS). Demographic and clinical variables, including age, menopausal status, and hormone receptors (HR), were analyzed. Results: The study included 318 PH-treated patients. The median age was 56 years, with 63.2% being postmenopausal and 60.4% HR and HER-2 positive. With a median follow-up of 17.2 months, the median OS was 29 months. OS varied based on HR status and the presence of metastases at different sites, significantly lower in patients with brain, cutaneous/subcutaneous, and pulmonary metastases. Additionally, OS was higher in patients treated at private institutions compared to public ones. Conclusions: This study demonstrates the disparity in oncological treatment efficacy between clinical trials and clinical reality in Uruguay, emphasizing the importance of authentic environment research for more representative and effective medicine in Latin America.

Implementing Standard Diagnosis and Treatment for Locally Advanced Breast Cancer Through Global Research in Latin America: Results From a Multicountry Pragmatic Trial.

PURPOSE: Breast cancer mortality rates in Latin America (LA) are higher than those in the United States, possibly because of advanced disease presentation, health care disparities, or unfavorable molecular subtypes. The Latin American Cancer Research Network was established to address these challenges and to promote collaborative clinical research. The Molecular Profiling of Breast Cancer Study (MPBCS) aimed to evaluate the clinical characteristics and treatment outcomes of LA participants with locally advanced breast cancer (LABC). PATIENTS AND METHODS: The MPBCS enrolled 1,449 participants from Argentina, Brazil, Chile, Mexico, and Uruguay. Through harmonized procedures and quality assurance measures, this study evaluated clinicopathologic characteristics, neoadjuvant chemotherapy response, and survival outcomes according to residual cancer burden (RCB) and the type of surgery. RESULTS: Overall, 711 and 480 participants in the primary surgery and neoadjuvant arms, respectively, completed the 5-year follow-up period. Overall survival was independently associated with RCB (worse survival for RCBIII-adjusted hazard ratio, 8.19, P < .001, and RCBII [adjusted hazard ratio, 3.69, P < .008] compared with RCB0 [pathologic complete response or pCR]) and type of surgery (worse survival in mastectomy than in breast-conserving surgery [BCS], adjusted hazard ratio, 2.97, P = .001). The hormone receptor-negative-human epidermal growth factor receptor 2-positive group had the highest proportion of pCR (48.9%). The analysis of the ASCO Quality Oncology Practice Initiative breast module revealed high compliance with pathologic standards but lower adherence to treatment administration standards. Notably, compliance with trastuzumab administration varied widely among countries (33.3%-88.7%). CONCLUSION: In LABC, we demonstrated the survival benefit of BCS and the prognostic effect of the response to available neoadjuvant treatments despite an important variability in access to key treatments. The MPBCS represents a significant step forward in understanding the real-world implementation of oncologic procedures in LA.

Assessing Adherence to Adjuvant Hormone Therapy in Breast Cancer Patients in Routine Clinical Practice.

Background: Adjuvant hormone therapy (HT) in patients with hormone receptor-positive breast cancer (BC) increases overall survival (OS). A lack of adherence to adjuvant endocrine therapy is common, 31.0-73.0% of women discontinue endocrine treatment before 5 years. The aim of the study was to assess adherence to HT in routine clinical practice in patients assisted at the Clinical Oncology Department of the Hospital de Clinicas - Universidad de la Republica, Uruguay. Methods: Patients treated with HT for stage 0-III BC between 2017 and 2019 were included. The medication possession (MPR) rate was calculated using pharmacy records, and the Morisky-Green Scale was applied to assess adherence. Adherent patients were those with MPR ≥ 0.80 and who correctly answered the Morisky-Green treatment adherence questionnaire. The association of adherence with polypharmacy, treatment, and patient characteristics was assessed using simple logistic models. The associations between qualitative variables and adherence were assessed using simple logistic regression model or Fisher's exact test. The association between quantitative variables and adherence was assessed using the Student's t-test. The odds ratio (OR) for non-adherence to treatment and its 95% confidence interval were estimated. Results: Totally, 118 patients were included; 65.2% were treated with aromatase inhibitors (AIs), 36.0% presenting polypharmacy. The adherence rate at the end of 2 years was 81.0 %; and it was associated with age (P = 0.03, OR = 0.96 for non-adherence), with adherent and non-adherent patients having a mean age of 65.0 and 60.3 years, respectively; however, adherence was not associated with polypharmacy, territory of origin, marital status, living alone, level of education, occupation, or stage. The adherence profile was similar for both drugs, but homemakers and retired women showed greater adherence to AI. Conclusions: Adherence to HT was assessed in real life, with 19.0% of the patients not adhering to the treatment, despite the known benefit for OS, being a well-tolerated treatment, and being provided free of charge. Older patients were associated with being more adherent. The results show the need of the Pharmacy Service and Department of Clinical Oncology Medical Oncology combining efforts to develop coordinated strategies and interventions to increase adherence, given the impact that this may have on patients' OS.

Trastuzumab-induced cardiotoxicity in early breast cancer over a 10-year period in Uruguay.

This srudy aimed to estimate the prevalence of trastuzumab-induced cardiotoxicity in Uruguayan women diagnosed with human epidermal growth factor receptor 2 (HER2)-positive breast cancer over a 10-year period, who were treated under the financial coverage of the National Resources Fund (Fondo Nacional de Recursos). This was an observational, descriptive study based on the analysis of an anonymized database of Uruguayan women diagnosed with HER2-positive breast cancer who received adjuvant trastuzumab treatment from to 2006 to 2016, provided by the Fondo Nacional de Recursos. Statistical analysis was performed using SPSS Statistics version 25, and variables were assessed using measures of central tendency, dispersion, contingency tables, and proportions. The chi-square test was used to analyze the association between the different variables. The study included 1401 patients diagnosed with stage I to III HER2-positive breast cancer. The mean age at diagnosis was 52 years. The prevalence of cardiotoxicity was 20.3%. Most patients who discontinued treatment owing to cardiotoxicity eventually resumed treatment (92.6%). Moreover, the prevalence of cardiotoxicity was similar among patients who received regimens with and without anthracyclines. No association was observed between prior cardiovascular events or trastuzumab administration (concurrent vs sequential) and the development of cardiotoxicity. In the present study, the prevalence of cardiotoxicity was similar to that reported nationally and internationally. Most patients did not develop cardiotoxicity, while the ones who developed it remained asymptomatic and cardiotoxicity was reversible.

Inclusion of information technology-based assessments of health-related quality of life in routine oncology practice in Uruguay.

BACKGROUND: Previous research has shown that the inclusion of patient-reported outcomes measures in the patient's visit to the oncologists might improve the quality of global health care. The aim of the study was to assess the feasibility, acceptance, and utility perceived by patients and oncologists of health-related quality of life (HRQL) assessments obtained prior to clinical visits, and to evaluate if this has an impact on patient's well-being in a sample of Spanish-speaking patients from Uruguay. METHODS: Patients assisted regularly in the Oncology Clinic were randomized into two groups: an intervention group that completed a set of questionnaires (European Organisation for Research and Treatment of Cancer-Quality of Life Questionnaire-C30 (EORTC QLQ-C30) and Hospital Anxiety and Depression Scale using a touch screen device and a control group that did not respond to these questionnaires. At 2 months, the responses of all the participants to the Functional Assessment of Cancer Therapy-General (FACT-G) were collected over a telephone to determine whether there were differences in the HRQL between the intervention and control groups. The graphed scores of the intervention group were included in the clinical history of the patient during consultation. Patients and physicians completed the questionnaires on the usefulness of these measurements. RESULTS: In total, 58 patients participated in this study: 36 in the intervention group and 22 in the control group; 65% of the participants were female, and median age was 59 years (18-79). Regarding patients, 97% found the questionnaires easy to complete and thought that they included important questions. As for oncologists, 68.8% used the information and 87.5% found it useful for the consultation. There were no significant differences in the FACT-G scores between the intervention and control groups. CONCLUSIONS: The routine HRQL assessments using an electronic device prior to the consultations were positively valued by almost all patients and physicians. This could significantly contribute to a better understanding of the patient's overall problems during consultation. These results confirm the benefits of integrating the patient's self-reported quality of life outcomes into consultations.

Socioeconomic, Clinical, and Molecular Features of Breast Cancer Influence Overall Survival of Latin American Women.

Molecular profile of breast cancer in Latin-American women was studied in five countries: Argentina, Brazil, Chile, Mexico, and Uruguay. Data about socioeconomic characteristics, risk factors, prognostic factors, and molecular subtypes were described, and the 60-month overall cumulative survival probabilities (OS) were estimated. From 2011 to 2013, 1,300 eligible Latin-American women 18 years or older, with a diagnosis of breast cancer in clinical stage II or III, and performance status ≦̸1 were invited to participate in a prospective cohort study. Face-to-face interviews were conducted, and clinical and outcome data, including death, were extracted from medical records. Unadjusted associations were evaluated by Chi-squared and Fisher's exact tests and the OS by Kaplan-Meier method. Log-rank test was used to determine differences between cumulative probability curves. Multivariable adjustment was carried out by entering potential confounders in the Cox regression model. The OS at 60 months was 83.9%. Multivariable-adjusted death hazard differences were found for women living in Argentina (2.27), Chile (1.95), and Uruguay (2.42) compared with Mexican women, for older (≥60 years) (1.84) compared with younger (≤40 years) women, for basal-like subtype (5.8), luminal B (2.43), and HER2-enriched (2.52) compared with luminal A subtype, and for tumor clinical stages IIB (1.91), IIIA (3.54), and IIIB (3.94) compared with stage IIA women. OS was associated with country of residence, PAM50 intrinsic subtype, age, and tumor stage at diagnosis. While the latter is known to be influenced by access to care, including cancer screening, timely diagnosis and treatment, including access to more effective treatment protocols, it may also influence epigenetic changes that, potentially, impact molecular subtypes. Data derived from heretofore understudied populations with unique geographic ancestry and sociocultural experiences are critical to furthering our understanding of this complexity.

The Transcriptomic Portrait of Locally Advanced Breast Cancer and Its Prognostic Value in a Multi-Country Cohort of Latin American Patients.

Purposes: Most molecular-based published studies on breast cancer do not adequately represent the unique and diverse genetic admixture of the Latin American population. Searching for similarities and differences in molecular pathways associated with these tumors and evaluating its impact on prognosis may help to select better therapeutic approaches. Patients and Methods: We collected clinical, pathological, and transcriptomic data of a multi-country Latin American cohort of 1,071 stage II-III breast cancer patients of the Molecular Profile of Breast Cancer Study (MPBCS) cohort. The 5-year prognostic ability of intrinsic (transcriptomic-based) PAM50 and immunohistochemical classifications, both at the cancer-specific (OSC) and disease-free survival (DFS) stages, was compared. Pathway analyses (GSEA, GSVA and MetaCore) were performed to explore differences among intrinsic subtypes. Results: PAM50 classification of the MPBCS cohort defined 42·6% of tumors as LumA, 21·3% as LumB, 13·3% as HER2E and 16·6% as Basal. Both OSC and DFS for LumA tumors were significantly better than for other subtypes, while Basal tumors had the worst prognosis. While the prognostic power of traditional subtypes calculated with hormone receptors (HR), HER2 and Ki67 determinations showed an acceptable performance, PAM50-derived risk of recurrence best discriminated low, intermediate and high-risk groups. Transcriptomic pathway analysis showed high proliferation (i.e. cell cycle control and DNA damage repair) associated with LumB, HER2E and Basal tumors, and a strong dependency on the estrogen pathway for LumA. Terms related to both innate and adaptive immune responses were seen predominantly upregulated in Basal tumors, and, to a lesser extent, in HER2E, with respect to LumA and B tumors. Conclusions: This is the first study that assesses molecular features at the transcriptomic level in a multicountry Latin American breast cancer patient cohort. Hormone-related and proliferation pathways that predominate in PAM50 and other breast cancer molecular classifications are also the main tumor-driving mechanisms in this cohort and have prognostic power. The immune-related features seen in the most aggressive subtypes may pave the way for therapeutic approaches not yet disseminated in Latin America.

Population-based screening of Uruguayan Ashkenazi Jews for recurrent BRCA1 and BRCA2 pathogenic sequence variants.

In Ashkenazi Jews (AJ) three recurring pathogenic sequence variants (PSVs) are detected in ~2.5% of the general population in the BRCA1 (c.68_69del = 185delAG, c.5266dup = 5382insC), and BRCA2 (c.5946del = 6174delT). Population-based screening for these PSVs in AJ women is part of the health basket in Israel. To assess the feasibility and outcome of BRCA genotyping in the Jewish population of Uruguay, AJ in the greater Montevideo area were recruited using ethically approved protocol and without pretest counseling were genotyped for the three predominant AJ PSVs in the BRCA genes. Independently confirmed PSV carriers were counseled, and genetic testing was offered to additional family members. Overall, 327 participants were enrolled: 312 (95%) female, 261 (80%) had all four grandparents AJ, and 14 (4%) women were breast cancer survivors with a mean age ± standard deviation (SD) 50 ± 11.5 years. The BRCA1 c.68_69del PSV was detected in three cancer free participants (0.92%, CI 95% 0.31-2.6), all with a suggestive family history. No carriers of the other two recurrent PSVs were detected. Online oncogenetic counseling was provided for all carriers. In conclusion, the rate of the BRCA1 c.68_69del PSV was similar with the rate in other AJ communities. AJ population BRCA genotyping screens in Uruguay seem feasible and should be promoted.

Survival and Time to Initiation of Adjuvant Chemotherapy Among Breast Cancer Patients in Uruguay.

INTRODUCTION: Increases in disease-free survival and overall survival (OS) with the use of adjuvant chemotherapy in early breast cancer (BC) are widely known; however, the optimal time to initiate treatment with adjuvant chemotherapy remains controversial. OBJECTIVE: To evaluate the time elapsed between surgery and the initiation of adjuvant chemotherapy and its possible impact on OS in patients diagnosed with BC stages I-III. MATERIALS AND METHODS: This retrospective study included 112 patients diagnosed with BC stages I-III who received adjuvant chemotherapy at the Mastology Unit of the Hospital de Clínicas in Uruguay from 2009 to 2019. OS was estimated using the Kaplan-Meier method, and a Cox proportional hazards model was used to estimate hazard ratios (HRs) and 95% confidence intervals. RESULTS: No statistically significant association was found between the time from surgery to the initiation of chemotherapy and the described variables. OS was worse for patients initiating chemotherapy more than 90 days after breast surgery (n = 19) (HR 7.63; p = 0.004) and between 61 and 90 days after surgery (n = 46) (HR 4.58; p = 0.040) compared to those who started before 30 days (n = 23). Controlling by type of surgery and stage, the prognosis of patients who started chemotherapy between 61 and 90 days after surgery was similar to that of patients who underwent chemotherapy within the first 30 days, controlling for surgery (HR 4.10; p = 0.056) and controlling for stage (HR 3.76; p = 0.075). Prognosis was worse for patients with stage III disease (p = 0.022) who underwent a mastectomy and/or axillary lymph node dissection (p = 0.025). CONCLUSION: Patients who started chemotherapy more than 90 days following surgery and those with stage III disease or underwent mastectomy and/or axillary lymph node dissection who initiated it between 61 and 90 days had a worse OS. Multiple factors are involved in the time between surgery and the initiation of chemotherapy, and further studies are needed to evaluate which of these factors influence the delay of chemotherapy in order to design strategies to avoid such delays and their negative impact on survival.

Impact of the COVID-19 pandemic on health care activities at a Uruguayan mastology unit.

PURPOSE: Health emergency due to COVID-19 started in Uruguay on March 13, 2020; our mastology unit tried to ensure adequate oncological care, and protect patients from the virus infection and complications. OBJECTIVE: To assess the health care activities in the "peak" of the pandemic during 3 months. MATERIALS AND METHODS: we collected data from the electronic health record. RESULTS: There were a total of 293 medical appointments from 131 patients (221 face-to-face), that decreased by 16.7% compared to the same period in 2019 (352 appointments). The medical appointments were scheduled to evaluate the continuity of systemic treatment or modifications (95 patients; 72.5%), follow-up (17; 12.9%), first-time consultation (12; 9.1%), and assess paraclinical studies (7; 5.3%). The patients were on hormone therapy (81 patients; 74%), chemotherapy (CT) (21; 19%), and anti-HER2 therapies (9; 8%). New twenty treatments were initiated. Of the 14 patients that were on adjuvant/neoadjuvant CT, 9 (64.3%) continued with the same regimen with the addition of prophylactic granulocyte-colony-stimulating factors (G-CSF), and 5 (35.7%), who were receiving weekly paclitaxel, continued the treatment with no changes. Of the seven patients that were on palliative CT, 2 (28.5%) continued the treatment with the addition of G-CSF, 3 (42.8%) continued with weekly capecitabine or paclitaxel with no treatment changes, and 2 (28.5%) changed their treatment regimen (a less myelosuppressive regimen was selected for one and due to progression of the disease in the other patient). The ninety patients who were receiving adjuvant, neoadjuvant, or palliative criteria hormone therapy and/or anti-HER2 therapies, continued the treatment with no changes. CONCLUSIONS: The evidence suggests that, although medical appointments decreased by approximately 17%, we could maintain healthcare activities, continued most of the treatments while the most modified was CT with G-CSF to avoid myelosuppression.

Prevalence of Known Risk Factors in Uruguayan Women Treated for Breast Cancer at a University Hospital.

INTRODUCTION: In Uruguay, breast cancer has the highest incidence and mortality of all cancer in women. Knowledge of the distribution of risk factors related to disease development supports the implementation of prevention strategies in routine clinical practice. This study aimed to determine the epidemiological profile for breast cancer and the frequency of mammographic surveillance in the surveyed population. MATERIALS AND METHODS: A survey was conducted among Uruguayan women diagnosed with breast cancer who were assisted in the mastology unit of the oncology service of the Hospital de Clínicas in Montevideo, Uruguay, from September 1, 2018, to March 1, 2020. RESULTS: This study included 398 respondents, with a median (SD) age at diagnosis of 61 (34-86) years. A total of 310 respondents (78.0%) had 1 or more risk factors. Most women aged over 50 years (264 out of a total of 338 [78.1%]) underwent mammographic surveillance at least biennially. CONCLUSIONS: Consistent with international reports, most respondents had a risk factor. Among the group of respondents aged over 50 years, most underwent mammographic and clinical surveillance at least biennially. Although it is only possible to formulate conclusions about the surveyed women because of the study design, the obtained data further our understanding of the epidemiological profile of the Uruguayan population, which can contribute to prevention practices.

Conclusión: la CT fue valorada con un alto grado de satisfacción y permitió mantener la asistencia durante la emergencia. Si bien es pronto para evaluar el impacto asistencial de la CT y su capacidad resolutiva, resultados preliminares muestran que es una herramienta útil y valiosa en la práctica clínica durante periodos de emergencia sanitaria.

Summary: Introduction: in March 2020, a national health emergency was declared due to the COVID-19, what resulted in changes in the organization of health services. One of the objectives of this restructure was to minimize in person consultations and to promote telephone consultations. that took place was a reduction in face-to-face consultations (FTFC), and the promotion of telephone consultations (TC). Objective: to evaluate the effectiveness of telephone consultations and the level of satisfaction of patients assisted at Mastology Department with this modality during the COVID 19 health emergency. Materials and methods: a survey was used to assess the effectiveness of telephone consultations and the level of satisfaction with this modality. Results: forty-two patients were surveyed, 69% of which were receiving adjuvant treatment and 14.2% of which were receiving palliative treatment. With regard to the effectiveness of telephone consultations, 76.1% of those surveyed had their need solved by telephone; 78.6% of patients preferred to do the consultation by telephone; 97.6% believed that sufficient time was spent and that the timing of the appointment was appropriate. The responses showed a high level of satisfaction with the care received. The medical care met the expectations of all patients, and 83.3% believed that once the situation went back to normal, telephone consultations would be an option for their requirements. Conclusion: the telephone consultation method was evaluated with a high level of satisfaction and it allowed health care services to be maintained during the emergency. Although it is early to assess the healthcare impact of telephone consultations and the modality's capacity to resolve issues, preliminary results show that it is a useful and valuable tool in clinical practice during periods of healthcare emergency.

Expresión tumoral de BRCA1 y resultados clínicos en pacientes uruguayas diagnosticadas de cáncer de mama antes de los 40 años / BRCA1 tumor expression and clinical results in uruguayan patients diagnosed with breast cancer before the age of 40 years old / Expressão tumoral de BRCA1 e resultados clínicos em pacientes uruguaias com diagnóstico de câncer de mama antes dos 40 anos

Resumen: Las mutaciones de BRCA1 son raras en el cáncer de mama (CM) esporádico; sin embargo, su expresión a nivel tumoral se encuentra disminuida o ausente en 30%-50% de los casos. Objetivo: valorar la expresión tumoral de BRCA1 por inmunohistoquímica (IHQ) en mujeres uruguayas diagnosticadas de CM antes de los 40 años. Material y método: se incluyeron pacientes diagnosticadas de CM antes de los 40 años. Se utilizaron los anticuerpos monoclonales anti-BRCA1 MS110 contra el extremo N-terminal y GLK-2 contra el extremo C-terminal. Se calculó la sobrevida global (SVG) y la sobrevida libre de enfermedad (SVLE), para la construcción de las curvas se utilizó el método de Kaplan-Meier y la diferencia de sobrevida se evaluó mediante el test de log rank. Resultados: se incluyeron 40 pacientes, la SVG y la SVLE a cinco años fueron de 73% y 60% respectivamente. La expresión de BRCA1 mediante GLK-2 fue <10% en 16 de las 40 pacientes (40%). La SVG y la SVLE a cinco años para las pacientes con expresión <10% fue de 56% vs 85% para las pacientes con expresión >10% (p=0,015) y de 40% vs 72% (p=0,034) respectivamente. La expresión de BRCA1 mediante MS110 fue <10% en 11 de las 40 pacientes (27,5%). No se encontraron diferencias en la SVG ni en la SVLE a cinco años con este marcador. Conclusión: la pérdida de la expresión tumoral de BRCA1 determinada mediante GLK-2 se encontró en el 40% de las pacientes incluidas y se asoció a una menor SVG y SVLE, por lo que podría tener un valor pronóstico desfavorable en estas pacientes.

Summary: BRCA1 mutations are rare in sporadic breast cancer (CM), however their expression at the tumor level is diminished or absent in 30-50% of cases. Objective: to assess the tumor expression of BRCA1 using immunohistochemistry (IHC) in Uruguayan women diagnosed with BC before the age of 40 years. Material and methods: patients diagnosed with BC before the age of 40 between. The antibodies used were anti BRCA1 MS110 monoclonal antibodies against the N-terminal end and GLK-2 against the C-terminal. Overall survival (OS) and disease free survival (DFS) were calculated; the curves were developed using the Kaplan-Meier method and the difference in survival was evaluated through the log rank test. Results: the average age of the 40 patients included was 36 years. The 5-year OS and DFS were 73% and 60% respectively. The expression of BRCA1 with GLK-2 was <10% in 16 of the 40 patients included (40%). The 5-year OS and DFS for patients with <10% expression was 56% vs. 85% for patients with >10% (p=0.015) and 40% vs. 72% (p = 0.034) respectively. The expression of BRCA1 by MS110 was <10% in 11 of the 40 patients included (27.5%). No differences were found in the 5-year OS or DFS based on the expression of this marker. Conclusion: The loss of BRCA1 expression using GLK-2, which suggests the presence of a truncated protein, was associated with a statistically significantly lower OS and DFS, that the decrease in the BRCA1 protein as determined by GLK2 has an unfavorable prognostic value for young patients with BC.

Effectiveness of Trastuzumab for Human Epidermal Growth Factor Receptor 2-Positive Breast Cancer in a Real-Life Setting: One Decade of Experience Under National Treatment Coverage Regulations.

PURPOSE: Trastuzumab has shown an overall survival (OS) benefit in patients with human epidermal growth factor receptor 2 (HER2)-positive breast cancer (BC), in both the adjuvant and the metastatic setting. We assessed the effectiveness of trastuzumab in patients treated in daily practice according to national treatment coverage protocols and compared our results with those reported by randomized clinical trials. These coverage protocols included patient selection criteria similar to those of those clinical trials and were developed by the Uruguayan National Resource Fund (FNR), the agency that has funded these prescriptions for more than a decade. PATIENTS AND METHODS: We included all patients with HER2-positive BC treated with trastuzumab under FNR coverage approved between January 1, 2006, and December 31, 2016. The source of data was the FNR database, and primary outcome was OS, analyzed through Cox proportional hazards regression analysis. RESULTS: A total of 1,944 women were included: 1,085 women (55.8%) were postmenopausal and 1,240 (63.7%) had HER2 and hormone receptor-positive BC. Trastuzumab was administered as adjuvant therapy to 1,233 patients (63.5%), of whom 154 also received it as a neoadjuvant treatment. Three hundred nineteen patients (16.4%) received trastuzumab for advanced disease. Five-year OS in the adjuvant setting was 86.4% (95% CI, 84.0% to 88.7%). The median survival of patients with advanced BC was 25.1 months (95% CI, 10.1 to 42.5 months). CONCLUSION: Our survival results are not inferior to those reported in clinical trials, in both adjuvant and advanced settings. Importantly, these results support the relevance and the feasibility of treating patients in routine practice, following coverage protocols based on patient selection criteria and methods supported by positive clinical trials. In addition, these results favor quality and appropriate access to BC treatment in our country.

Síndrome de Li Fraumeni: análisis clínico de un caso y revisión de la literatura / Li-Fraumeni syndrome: clinical case study and literature survey / Síndrome de Li Fraumeni: análise clínica de um caso e uma revisão da literatura

Resumen: El síndrome de Li-Fraumeni (SLF) es una enfermedad hereditaria autosómica dominante con elevada penetrancia, que se caracteriza por la aparición precoz de múltiples tumores en un individuo y una marcada agregación familiar. Aproximadamente el 70% de los pacientes que cumplen criterios clínicos para su diagnóstico son portadores de la mutación germinal del gen TP53 localizado en el cromosoma 17p13. El gen TP53 es un supresor tumoral que cumple una importante función en el control de la estabilidad genómica. Se estima que el riesgo de desarrollar cáncer es del 50 % para las mujeres a los 31 años de edad y para los hombres a los 46 años y cerca del 100 % para ambos sexos a los 70 años. El curso clínico de la enfermedad es similar que en pacientes sin SLF a excepción de la edad más temprana al diagnóstico. Presentamos el caso de una paciente de 31 años a la que se diagnostica un condrosarcoma pelviano tratado con cirugía y al momento de la recidiva, aproximadamente 8 meses después, un cáncer de mama localizado. En otro miembro de su familia se había identificado la mutación 375G>C en el gen TP53 mediante secuenciación Sanger, la cual fue detectada posteriormente en nuestra paciente. Se discuten aspectos particulares del manejo como la minimización de la exposición a la radioterapia (por reportes de tumores malignos en zonas irradiadas) y el especial manejo de la repercusión del diagnóstico a nivel de los otros integrantes de la familia.

Abstract: The Li-Fraumeni syndrome (SLF) is a highly penetrant condition with an autosomal dominant inheritance pattern, characterized by an early onset of multiple tumors in a subject and a marked familial occurrence. About 70 % of patients meeting clinical criteria for diagnosis of the disease carry the germline mutation of TP53 gene located in chromosome 17p13. TP53 is a tumor suppressor gene known for its major role in genome stability control. It has been estimated that risk of cancer development is 50 % for women at the age of 31 and for men at the age of 46 and nearly 100 % for both men and women at 70 years of age. Except at earlier ages of diagnosis, the clinical course of the disease for healthy patients and for patients suffering SLF shows similarities. We present the case of a 31-year-old patient diagnosed both with pelvic chondrosarcoma treated surgically and localized breast cancer during relapse, about 8 months later. By Sanger sequencing, mutation 375G>C had been identified in TP53 gene in another family member, and said mutation was later detected in our patient. We discuss particular aspects of treatment procedures, such as minimizing radiotherapy exposure (due to reports of malignancies in radiated areas) and the special management of diagnosis implications for other family members.

Resumo: A síndrome de Li-Fraumeni (SLF) é uma doença hereditária autorexistente dominante com pena de penetração, que caracteriza a aparição precoz de múltiplos tumores em um indivíduo e uma coletânea familiar. Aproximadamente o 70% dos pacientes com critérios clínicos para o diagnóstico em crianças portadores da mutação germinal do gen TP53 localizado no cromosoma 17p13. El gen TP53 é um tumor tumoral que cumple uma função importante no controle da estabilização genómica. Se estima que o riesgo do desengate faz dos 50% para as mulheres aos 31 anos de idade e para os 40 anos e cerca de 100% para ambos os sexos aos 70 anos. O curso clínico da doença é semelhante ao que ocorre com a SLF a exceção da doença mais tem sido diagnosticada. Presentamos o caso de um paciente de 31 años que diagnostica um paciente de pélvico com relato ao momento da recidiva, aproximadamente 8 meses depois, em um lugar de mama próximo. En otio miembro de la familia se habiocuident to the mutación 375G> C en el gen TP53 por secuenciación Sanger, a cual fue detectada em recente paciente. A discussão foi feita sobre os aspectos do tratamento com a minimização da exposição à radioterapia (por tumores malignos em zonas irradiadas) e o especial manejo da repercussão do diagnóstico a nível dos otros integrantes da familia

RESUMEN: Introducción: En los últimos años ha adquirido gran relevancia evaluar la satisfacción de los usuarios con los servicios sanitarios, lo que se asocia en forma significativa con los resultados obtenidos en salud. La satisfacción de los pacientes juega un importante papel en el mantenimiento de la utilización de los servicios de salud, en la continuidad de la relación médico-paciente y en la adherencia a los tratamientos indicados. Objetivos: Conocer el grado de satisfacción manifestado por las pacientes asistidas en la Unidad Docente Asistencial de Mastología del Hospital de Clínicas e identificar los aspectos a mejorar. Material y métodos: Estudio prospectivo, aprobado por el comité de ética del Hospital de Clínicas, en el que se aplicó una encuesta anónima de satisfacción con 13 preguntas cerradas y una abierta y se recogieron datos sobre la edad y tipo de tratamiento oncológico recibido. Resultados: Se encuestaron 91 pacientes que concurrieron a la consulta en un período de dos meses. Las respuestas muestran un alto grado de satisfacción de las pacientes con la asistencia global recibida, con una puntuación media de 3,26 (IC 95% 3.18-3.34) (rango: 1: pobre; 5: excelente), siendo este resultado independiente del grupo etario y del tipo de tratamiento oncológico recibido. Sin embargo el 38,5 % de las pacientes que trabaja piensa que no pudo discutir el impacto de la enfermedad en su trabajo (media 1,82; IC 95% 1,66-1,97) (rango 0: nada; 3: tanto como quise) y un 27 % del total de las encuestadas piensa que no pudo discutir el impacto que su enfermedad tuvo en sus actividades diarias (media 2,13 IC 95% 2,12 - 2,14) (rango: 0 : nada ; 3: si tanto como quise) ni en sus relaciones personales (27; 30 %, media 2,0 IC 95% 1,93-2,2) (rango: 0: nada ; 3: si tanto como quise). Conclusiones: La puntuación global es muy satisfactoria, con dimensiones que deben mejorarse con un mayor énfasis en la comunicación sobre el impacto de la enfermedad en las actividades diarias, las relaciones personales y el trabajo. Consideramos importante implementar evaluaciones periódicas de la calidad de atención que permitan comparar los resultados y desarrollar un proceso de mejora continua.

ABSTRACT: Introduction: During the last years, assessing the degree of patient satisfaction of health services has become extremely important; and it is more often associated to the results obtained in terms of health. The degree of patient satisfaction plays a significant role in fostering the use of health care services, in developing the physician-patient relationship and in adhering to indicated treatments. Objective: To find out the degree of patient satisfaction at the Breast Teaching and Care Unit at Hospital de Clinicas and identify aspects that need improving. Materials and methods: prospective study, approved by the ethics committee of Hospital de Clinicas, where an anonymous satisfaction survey, with 1 open and 13 closed questions, was conducted. The survey also included data related to the age and oncological treatment received. Results: Over two months, 91 assisting patients were interviewed. Responses show a high degree of satisfaction of patients with the global care received, with a mean score of 3.26 (CI 95 % 3.18-3.34) (range: 1: poor; 5: excellent), regardless of age group and the type of oncological treatment received. However, 38.5 % of working patients believe that they were not able to discuss the impact of their disease at their jobs (mean 1.82; CC 95% 1.66-1.97) (range: 0: not at all; 3: as much as I wanted) and 27 % of patients consider that they were not able to discuss the impact of their disease on their daily activities (mean 2.13; CI 95 % 2.12 - 2.14) (range: 0: not at all; 3: as much as I wanted) or their personal relations (27; 30 %, mean 2.0 CI 95 % 1.93-2.2) (range: 0: not at all; 3: as much as I wanted). Conclusions: The global score is very satisfactory, and there are aspects to be improved, such as a better communication on the impact of the disease on daily activities, personal relations and work. We believe it is important to implement regular assessments of assistance quality that may enable to compare results and develop a continuous improvement process.

RESUMO: Introdução: Nos últimos anos, tornou-se muito importante avaliar a satisfação dos usuários com serviços de saúde, o que está significativamente associado aos resultados obtidos em saúde. A satisfação do paciente desempenha um papel importante na manutenção do uso dos serviços de saúde, na continuidade da relação médico-paciente e na adesão aos tratamentos indicados. Objetivos: Conhecer o grau de satisfação expressado pelos pacientes atendidos na Unidade de Assistência de Ensino de Mastologia do Hospital de Clínicas e identificar os aspectos a serem melhorados. Material e métodos Estudo prospectivo, aprovado pelo comitê de ética do Hospital de Clínicas, no qual foi aplicada uma pesquisa de satisfação anônima com 13 perguntas fechadas e uma aberta e dados coletados sobre a idade eo tipo de tratamento oncológico recebido. Resultados: Foram entrevistados 91 pacientes que participaram da consulta em um período de dois meses. As respostas mostram um alto grau de satisfação do paciente com a assistência geral recebida, com uma pontuação média de 3,26 (IC 95% 3,18-3,34) (intervalo: 1: pobre; 5: excelente), sendo este resultado independente da faixa etária e o tipo de tratamento contra o câncer recebido. No entanto, 38,5% dos pacientes que trabalham pensam que não poderiam discutir o impacto da doença em seus trabalhos (média 1,82, IC 95%: 1,66-1,97) (intervalo 0: nenhum; tanto quanto eu queria) e 27% do total de entrevistados pensam que não poderiam discutir o impacto que sua doença teve em suas atividades diárias (média 2.13 IC 95% 2.12 - 2.14) (intervalo: 0: nada ; 3: sim, tanto quanto eu queria) ou em seus relacionamentos pessoais (27; 30%, média 2,0 IC 95% 1,93-2,2) (classificação: 0: nada; 3: sim, tanto quanto eu queria). Conclusões: A pontuação geral é muito satisfatória, com dimensões que devem ser melhoradas com maior ênfase na comunicação sobre o impacto da doença nas atividades diárias, nas relações pessoais e no trabalho. Consideramos importante implementar avaliações periódicas da qualidade dos cuidados que nos permitem comparar os resultados e desenvolver um processo de melhoria contínua.
