RESUMO

Introduction: Nutritional exposure is considered the main environmental influence that contributes to gallstone disease (GD). Aim: The aim of this study was to determine food intakes patters and estimate risk of GD. Methods: A nested case-control study was carried out within the framework of a previous screening study conducted on a representative sample in Rosario, Argentina. Participants underwent a personal interview. Average amount of each food intake and quantity nutrients were estimated applying a food-frequency questionnaire. Food consumption patterns were identified by principal component analysis, and logistic regression analysis was used to estimate risks. Results: The sample was conformed by 51 cases and 69 controls. Two dietary patterns were identified. Cases were characterised by the unhealthy intake pattern (high intakes of animal fats, sugar, cereals, grains, cold cuts, processed meats, chicken with skin, fat beef and low intake of red vegetables and yellows, cabbages, fruits and fish). Conclusion: Controls were characterised by the healthy intake pattern (high intake of skinless chicken, nuts, lean beef, vitamin A and C rich fruits, and low consumption of chicken with skin, green leaves vegetables and sprouts). The unhealthy pattern showed an increased risk of developing GD while healthy patter behaved as a protective factor.


Introducción: La exposición nutricional se considera la principal exposición ambiental que contribuye a la formación de cálculos biliares. Objetivo: El objetivo de este trabajo fue determinar el patrón de consumo alimentario de casos y controles de EC y estimar el riesgo de desarrollar la enfermedad según los distintos patrones constituidos. Métodos: Se llevó a cabo un estudio analítico retrospectivo transversal de casos y controles, anidado a un estudio de prevalencia realizado en Rosario. Todos los participantes fueron entrevistados personalmente. El consumo de alimentos se consignó a través de un cuestionario semi-cuantitativo de frecuencia de consumo. Para determinar patrones de consumo alimentario se realizó un análisis de componentes principales, y análisis de regresión logística múltiple para evaluar riesgos. Resultados: La muestra quedó conformada por 51 casos y 69 controles. Se determinaron dos componentes que permitían diferenciar los casos de los controles, a través de las cuales se establecieron 2 patrones de consumo. Los casos se caracterizaron por un consumo determinado por el Patrón Poco saludable (altas ingestas de grasas animales, azúcar, cereales, granos, fiambres y embutidos) y los controles por el consumo del patrón Saludable (altas ingestas de pollo sin piel, frutas secas, carne vacuna magra, frutas, lácteos enteros). El patrón Poco saludable, aumentó el riesgo de desarrollar EC mientras que el patrón Saludable, se comportó como protector. Conclusión principal: Los patrones constituidos diferencian los casos de los controles, y la ingesta propia de los casos se correlaciona con un perfil de consumo que caracteriza a las culturas occidentales modernas y urbanas.

RESUMO

INTRODUCTION: There is limited literature on the prevalence of EGFR mutations in early stage NSCLC. EARLY-EGFR (NCT04742192), a cross-sectional study, determined the prevalence of EGFR mutations in early stage NSCLC. METHODS: This noninterventional, real-world study enrolled consecutive patients with resected stages IA to IIIB (American Joint Committee on Cancer eighth edition) NSCLC from 14 countries across Asia, Latin America, and the Middle East and Africa. The primary end point was prevalence of EGFR mutations and secondary end points included prevalence of EGFR mutation subtypes and treatment patterns. RESULTS: Of 601 patients (median [range] age: 62.0 [30.0-86.0] y) enrolled, 52.7% were females and 64.2% were nonsmokers. Most had stages IA to IB NSCLC (64.1%) and adenocarcinoma (98.7%). Overall prevalence of EGFR mutations was 51.0%; most reported exon 19 deletions (48.5%) followed by exon 21 L858R mutations (34.0%). Women had a higher EGFR mutation rate than men (64.0% versus 36.4%). Compared with no EGFR mutations, patients with EGFR mutations were more likely to be nonsmokers (35.1% versus 60.9%) and have stage I NSCLC than stages II and III NSCLC (54.8% versus 47.3% and 35.6%). Systemic adjuvant therapy was planned in 33.8% of the patients with stages IB to IIIB disease and adjuvant chemoradiotherapy in 6.8%. Age above or equal to 60 years, females, and Asians were found to have a significantly (p < 0.05) higher odds of EGFR mutations, whereas smoking history and stage III disease had lower odds of EGFR mutations. CONCLUSIONS: The EARLY-EGFR study provides an overview of EGFR mutations and subtype prevalence in patients with early stage NSCLC. The study highlights the limited adherence to treatment guidelines suggesting an unmet need for improved adjuvant therapy.

RESUMO

Lung cancer is a leading cause of cancer-related deaths in Latin America, with non-small cell lung cancer (NSCLC) being the most prevalent. The current study aimed to report real-world data on epidermal growth factor receptor (EGFR) mutational testing and treatment regimens at diagnosis and progression in patients with metastatic NSCLC across four Latin American countries (Argentina, Chile, Colombia and Uruguay). A retrospective, multicenter, observational study was conducted in patients with NSCLC using medical records from participating countries. The study population was categorized into two cohorts: Cohort 1 comprised of newly diagnosed, treatment-naïve patients with stage IV NSCLC; and cohort 2 comprised of stage IV NSCLC EGFR mutation (EGFRm)-positive patients who had progressed after first- or second-generation EGFR-tyrosine kinase inhibitor (TKI) treatment. Measures included demographic variables, health characteristics, treatment regimen, molecular testing rate and turnaround time at diagnosis and at progression for cohorts 1 and 2, respectively. Descriptive statistics were used to summarize all study measures. Of the 462 patients enrolled, 431 were newly diagnosed or treatment naïve with metastatic NSCLC. In cohort 1, the majority of patients with private health insurance (57.31%) underwent molecular diagnosis while only 41.3% of patients within the public sector had access to testing. The average molecular testing rate in cohort 1 varied across countries, with Argentina having the highest testing rate (79%) and Uruguay the lowest (27.63%). EGFRm was observed in 22% of patients. Cohort 2 comprised 31 patients who had progressed after first- or second-generation EGFR-TKI treatment and of these, only 22 (70.97%) underwent testing after progression. Access to molecular testing is still a challenge impacting the choice of first-line treatment in Latin American patients with NSCLC. These findings underline the unmet needs of ensuring early diagnosis, molecular profiling and use of correct treatment to alleviate NSCLC burden in the region.

RESUMO

Two interesting therapeutic proposals for cancer treatment emerged at the beginning of the 21st century. The first one was metronomic chemotherapy, which refers to the chronic administration of chemotherapeutic agents, in low doses, without extended drug-free periods. Then, the idea of drug repositioning in oncology, the use of well-known drugs that were created for other uses to be utilized in oncology, gained strength. Shortly after, the two strategies were merged in one, named metronomics. Both approaches share several features which make metronomics an appealing choice for cancer treatment: use of known and approved drugs, thus diminishing the time necessary to enter to the clinic, therapeutic effect, low toxicity, oral administration, better life quality, low costs because of the use of, generally, out of patent drugs, possibility of use, even in countries with very low economic resources. Many chemotherapy and repurposed drugs were tested with metronomics approaches for the treatment of mammary cancer, the most common malignancy in women worldwide, leading to high rates of mortality. The wide range of therapeutic models studied, paralleled the wide range of responses obtained, like tumor growth and metastasis inhibition, overall survival increase, lack of toxicity, better life quality, among others. The accomplishments reached, and the challenges faced by researchers, are discussed.

RESUMO

Identifying tumor biomarkers associated with clinical behavior in breast cancer patients may allow higher accuracy in the selection of treatment. Different types of cells were determined in the primary tumors of stage I, II, and III of breast cancer patients, who were assigned to one of the two groups: (1) disease-free or (2) relapsed/progressed, at 5 years after primary treatment. We studied 32 tumor samples. CD4+ lymphocytes and CD44+CD24-/low cells (cancer stem cells) showed a significant association with clinical outcome at 5 years of primary treatment, while CD8+, Foxp3+, CD34+, and myeloid-derived suppressor cells did not show any association. Coincident with the results of individual analysis, we identified CD4+ cells and CD44+CD24-/low cells as good predictors of long-term clinical outcome in a logistic regression.

RESUMO

Ovarian cancer (OC) is the leading cause of death from gynaecological cancer. It is extremely hard to diagnose in the early stages and around 70% of patients present with advanced disease. Metronomic chemotherapy (MCT) is described as the chronic administration of, generally low, equally spaced, doses of chemotherapeutic drugs with therapeutic efficacy and low toxicity. This is an effective and low-cost way to treat several types of tumours, including ovarian cancer. Here, we present six cases of advanced ovarian cancer treated with MCT with low doses of cyclophosphamide, which showed clinical response and stable disease.

RESUMO

AIM: The objective of the study was to detect changes in quality of life (QoL) in metastatic breast cancer patients treated with metronomic chemotherapy with daily low doses of cyclophosphamide and celecoxib. MATERIAL & METHODS: Patients included in a Phase II trial, treated with metronomic cyclophosphamide and celecoxib were included in the QoL study. Assessment of QoL was carried out every 2 months by the Functional Assessment of Cancer Therapy Breast (FACT-B) questionnaire, Brief Pain Inventory and Eastern Cooperative Oncologic Group scale. Data were analyzed at three time points: baseline (BL); middle of treatment (MT); and end of treatment (ET). RESULTS: A total of 20 patients were included. All patients were heavily pretreated. Treatment showed a good and safe therapeutic profile. With FACT-B questionnaire, no significant differences were observed during the response period (BL-MT). However, a significant increase was observed in the Emotional well-being and Additional concerns axes, when the last time point was included in the analysis (BL-MT-ET). A significant decrease in the proportion of patients with pain was found when comparing BL with ET (p = 0.046). The assessment with Eastern Cooperative Oncologic Group scale showed that 26.7% (4/15) of the patients improved their functional status and 40% (6/15) showed no changes, while 33.3% (5/10) worsened it. CONCLUSION: Patients treated metronomically for several months did not worsen their QoL. A high proportion of patients showed improvement or no changes and there were less patients with pain at the end of the treatment.

RESUMO

BACKGROUND: Preclinical results showing therapeutic effect and low toxicity of metronomic chemotherapy with cyclophosphamide (Cy) + celecoxib (Cel) for mammary tumors encouraged its translation to the clinic for treating advanced breast cancer patients (ABCP). PATIENTS AND METHODS: A single-arm, mono-institutional, non-randomized, phase II, two-step clinical trial (approved by Bioethics Committee and Argentine Regulatory Authority) was designed. Patients received Cy (50 mg po.d) + Cel (200 mg p.o.bid). Patient eligibility criteria included: ABCP who progressed to anthracyclines, taxanes and capecitabine, ≤4 chemotherapy schemes, with good performance status. Several pro- and anti-angiogenic molecules and cells were determined as biomarkers. Informed consent was signed by all patients. Primary endpoint was clinical benefit (CB). RESULTS: Twenty patients were enrolled. Main clinical outcomes were prolonged disease stabilization and partial remission in 10/20 and 1/20 patients, respectively. CB was 55 %, and time to progression (TTP) was 21.1 weeks. Median TTP in patients who achieved CB was 35.6 weeks, and mean overall survival was 44.20 weeks. There were no grade 3/4 toxicities associated with treatment. Circulating endothelial cells (CECs) increased at the time of progression in patients who showed CB (P = 0.014). Baseline CECs and circulating endothelial progenitor cells showed marginal associations with TTP. Serum VEGF decreased (P = 0.050), sVEGFR-2 increased (P = 0.005) and VEGF/sVEGFR-2 ratio decreased during treatment (P = 0.041); baseline VEGF and VEGF/sVEGFR-2 were associated with TTP (P = 0.035 and P = 0.030, respectively), while sVEGFR-2 did not. CONCLUSIONS: Treatment was effective, showing low toxicity profile and excellent tolerability. The combination had anti-angiogenic effect. Increased levels of CEC could be useful for detecting progression. Baseline VEGF and VEGF/sVEGFR-2 values could be useful as early predictors of response. TRIAL REGISTRATION: ANMAT#4596/09.

RESUMO

Metronomic chemotherapy (MCT), the chronic administration, at regular intervals, of low doses of chemotherapeutic drugs without extended rest periods, allows chronic treatment with therapeutic efficacy and low toxicity. Our preclinical results suggested that combined MCT with cyclophosphamide and celecoxib could inhibit breast cancer growth. The aim of this study was to determine the toxicity, safety and efficacy of oral MCT with cyclophosphamide 50 mg per orem daily and celecoxib 400 mg (200 mg per orem two-times a day) in advanced breast cancer patients. During the first stage of the study, the therapeutic response consisted of prolonged stable disease for ≥24 weeks in six out of 15 (40%) patients with a median duration of 37.5 weeks and a partial response in one out of 15 (response rate: 6.7%) patients lasting 6 weeks. The overall clinical benefit rate was 46.7%. The median time to progression was 14 weeks. Progression-free survival at 24 weeks was 40% and the 1-year overall survival rate was 46.7%. The adverse events were mild (gastric, grade 1; and hematologic, grade 1 or 2). No grade 3 or 4 toxicities were associated with the treatment. Evaluation of patients' quality of life showed no changes during the response period. MCT with cyclophosphamide plus celecoxib is safe and shows a therapeutic effect in advanced breast cancer patients.

RESUMO

En un estudio realizado en una muestra aleatoria de adultos de Rosario se encontró una tasa de prevalencia de Enfermedad Colelitiásica (EC) del 20,5%. Con el objetivo de determinar el patrón de consumo alimentario de estas personas y compararlo con las Raciones Dietéticas Recomendadas (RDA) se entrevistaron 44 de dichas personas con EC. Se les realizó una encuesta sobre hábitos alimentarios 5 años previos al diagnóstico, empleando un cuestionario semi-cuantitativo de frecuencia de consumo (FFQ) y un Atlas fotográfico de porciones estandarizadas. Se calcularon los promedios (± desvío estándar) de la edad, del Índice de Masa Corporal (IMC), del consumo de cada nutriente y de la energía total consumida (Kilocalorías). La significación estadística de las diferencias entre sexos se evaluó aplicando pruebas t de student. La edad de las personas estudiadas (18 varones y 26 mujeres) fue 63,8±13,8 años y el IMC fue 28,2±5,8. Consumos promedio diarios: Kcalorias 2941±791,1 ; Carbohidratos 295,3±96,9 g; Proteínas 131,6±36,8 g; Grasa 128,9± 43 g; Ácidos grasos saturados 41,9±18,6 g; Ácidos grasos poliinsaturados 13,8±8,7 g; Colesterol 455,4±186,8 mg; Sodio 2730±1552,1 mg; Potasio 2912,8±1001,4 mg; Calcio 719,3±403,3 mg; Hierro 16±4,6 mg; Fósforo 801,6±320,3 mg; Vitamina A 3121,7±1811,9 mcg; Vitamina B1 0,80±0,30 mg; Vitamina B2 1,9±0,8 mg; Vitamina C 157,6±114,1 mg; Niacina 6,9±2,7 mg; Fibra total 12± 5,3 g; Café 70,7±104,3 cc. Se concluye que el patrón alimentario de las personas con EC se caracterizó por un alto consumo de Grasas, Ácidos grasos saturados y Colesterol, no alcanzando las recomendaciones para Carbohidratos, Calcio, Niacina y Fibra.


Food intake pattern in a sample of adults with Gallbladder Disease (GD). In Rosario, Argentina, a 20,5% prevalence rate of Gallbladder Disease (GD) was found in a random sample of adults. The aim of this study was to determine the food consumption pattern of subjects with GD nested in that sample for further comparison with the Recommended Dietary Allowances (RDA). Forty-four subjects were interviewed about the food consumption during the five years before their diagnosis, by applying a semi-quantitative food frequency questionnaire (FFQ) and a photographic atlas of standardized portions. Age, body mass index (BMI), all consumed nutrients, and total energy intake (kilocalories) were reported as Mean ± standard deviation. Comparisons according to sex (18 males and 26 females) revealed no significant differences in the variables under analysis. Age and BMI in the overall sample were as follows 63.8±13.8 years and 28.2±5.8, respectively. Mean daily consumption of nutrients was as follows: Carbohydrates 295.3±96.9 g , Protein 131.6±36.8 g , Fat 128.9±43 g , Saturated fatty acids 41.9±18,6 g, Polyunsaturated fatty acids 13.8±8.7 g, Cholesterol 455.4±186.8 mg, Sodium 2730±1552.1 mg, Potassium 2912.8±1001.4 mg, Calcium 719.3±403.3 mg, Iron 16±4.6 mg, Phosphorus 801.6±320.3 mg, Vitamin A 3121.7±1811.9 mcg, Vitamin B1 0.80±0.30 mg, Vitamin B2 1.9±0.8 mg, Vitamin C 157.6±114.1 mg, Niacin 6.9±2.7 mg, Fiber 5.3±12 g, Coffee 70.7±104.3 cc (total energy intake 2941±791.1 Kcal). Subjects with GD have a history of higher intake of fat, saturated fatty acids and cholesterol with consumption of carbohydrates, calcium, niacin and fiber below the recommended quantities.
