ABSTRACT

Quimioterapia neoadyuvante (NAC) en cáncer de mama permite conocer la sensibilidad del tumor al tratamiento, alcanzar respuesta patológica completa (pRC), está asociada a mejor supervivencia en cáncer de mama localmente avanzado. El objetivo de este estudio fue conocer el impacto de la pRC en la supervivencia en una cohorte de pacientes tratadas con NAC y cirugía. Se realizo un estudio de diseño observacional de tipo retrospectivo, correlacional, con un seguimiento promedio de 90 meses, de una cohorte de pacientes tratadas con NAC y cirugía desde enero del 2009 a diciembre del 2011. El análisis de datos se realizó mediante el software estadístico SPSS v22.0, para el análisis de supervivencia se utilizó el método de Kaplan Meier, para comparar supervivencias se consideró significativa una p<0,05. Entre las características principales de 199 pacientes, se destacan: edad joven a la presentación, elevado índice de proliferación y alta frecuencia del tipo inflamatorio. pRC ocurrió en el 14,1% de pacientes y la supervivencia global (SG) de acuerdo con la respuesta patológica se comparó entre aquellas pacientes que obtuvieron pRC, con las que tuvieron enfermedad residual, con una SG del 71,4% vs 45% respectivamente, con una diferencia significativa (p:0.009). En esta cohorte de pacientes la pRC impactó en la supervivencia en todos los subtipos clínico-patológicos, sobre todo en el subtipo triple negativo. Evaluar los datos en el entorno real es importante para definir estrategias y mejorar los resultados.


Neoadjuvant chemotherapy (NAC) in breast cancer allows knowing the sensitivity of the tumor to treatment, achieving pathological response complete (pRC), and is associated with better survival in locally advanced breast cancer. The objective of this study was to determine the impact of pRC on survival in a cohort of patients treated with NAC and surgery. A retrospective, correlational observational design study was carried out, with an average follow-up of 90 months, of a cohort of patients treated with NAC and surgery from January 2009 to December 2011. Data analysis was performed using the software SPSS v22.0 statistic, for the survival analysis the Kaplan Meier method was used, to compare survivals a p <0.05 was considered significant. Among the main characteristics of 199 patients, the following stand out: young age at presentation, high proliferation index and high frequency of the inflammatory type. pRC occurred in 14.1% of patients and overall survival (OS) according to the pathological response was compared between those patients who obtained pRC, with those who had residual disease, with an OS of 71.4% vs 45% respectively, with a significant difference (p: 0.009). In this cohort of patients, pRC impacted on survival in all clinicopathological subtypes, especially in the triple negative subtype. Evaluating data in the real environment is important to define strategies and improve results.

ABSTRACT

BACKGROUND: Involvement with Child Protective Services (CPS) provides an opportunity to recognize those children at risk for ongoing adverse childhood experiences (ACEs). The relationship between ACEs and child health among CPS-involved children and the role of primary care providers (PCPs) in moderating this relationship is unknown. METHODS: We conducted a convergent mixed-methods study of caregivers of children age 2 to 12 years with a CPS finding of physical abuse, modeling the association between cumulative ACEs and child health-related quality of life (HRQoL) using the PedsQL4.0, a validated 23-item survey of multidimensional health, with and without the moderator of a patient-centered medical home. Interviews elicited descriptions of a child's experience with ACEs, the impact of ACEs on child health, and the role of a PCP in this context. RESULTS: One hundred seventy-eight surveyed caregivers reported a mean of 5.5 (±3.3) ACE exposures per child. In a fully adjusted model, each ACE resulted in a 1.3-point (95% confidence interval: 0.7-2.0) reduction in HRQoL, a clinically important difference in HRQoL associated with ACE exposures. This association was explained by reduced psychosocial HRQoL and was not moderated by a patient-centered medical home. Twenty-seven interviewed caregivers described the influence of ACEs on a child's health. Many felt that a trusted PCP could support a child's well-being after such experiences. CONCLUSIONS: Children with CPS involvement have ACE exposures that are associated with reduced HRQoL. Although PCPs are often unaware of CPS involvement or other ACEs, many caregivers welcome the support of a child's PCP in improving child well-being after adversity.

ABSTRACT

OBJECTIVE: To generate recommendations on the management of radiotherapeutic treatments during the pandemic, adapted to a country with limited health resources. METHODS: We did a rapid review of the literature, searching for papers that describe any measures to reduce the risk of COVID-19 infection, as well as management guidelines to reduce the workload, in radiotherapy units. The following conditions were included in the scope of this review: gynecological tumors, breast cancer, gastrointestinal tumors, genitourinary tumors, head and neck tumors, skin cancer, tumors of the central nervous system, and lymphomas. An expert group discussed online the extracted data and drafted the recommendations. Using a modified Delphi method, the consensus was reached among 14 certificated radio-oncologists. The quality of the evidence that supported the recommendations on treatment schedules was assessed. RESULTS: A total of 57 documents were included. Of these, 25 provided strategies to reduce the risk of infection. Recommendations for each condiction were extracted from the remaining documents. The recommendations aim to establish specific parameters where treatments can be omitted, deferred, prioritized, and shortened. Treatment schemes are recommended for each condition, prioritizing hypo-fractionated schemes whenever possible. CONCLUSIONS: We propose strategies for the management of radiotherapy services to guarantee the continuity of high-quality treatments despite the health crisis caused by COVID-19.


OBJETIVO: Establecer recomendaciones para la toma de decisiones de manejo en radioterapia durante la pandemia de COVID-19, adaptadas a un país con recursos de salud limitados. MÉTODOS: A través de una revisión rápida de la literatura se buscaron publicaciones que describieran medidas para reducir el riesgo de infección por COVID-19, así como también pautas de manejo para reducir la carga de trabajo en las unidades de radioterapia. Se incluyeron en el alcance de esta revisión las siguientes patologías: tumores ginecológicos, cáncer de mama, tumores gastrointestinales, tumores genitourinarios, tumores de cabeza y cuello, cáncer de piel, tumores del sistema nervioso central y linfomas. Un grupo de expertos discutió en línea los datos extraídos y redactó las recomendaciones. Mediante un método Delphi modificado, se evaluó el consenso entre 14 radio-oncólogos certificados. Se evaluó la calidad de la evidencia que sustentó las recomendaciones sobre esquemas de tratamiento. RESULTADOS: Se incluyeron un total de 57 documentos. De 25 trabajos se extrajeron las estrategias para reducir el riesgo de infección. De los restantes, se obtuvieron las recomendaciones para cada patología. Las recomendaciones están orientadas a establecer escenarios específicos donde se pueden omitir, diferir, priorizar y acortar los tratamientos. En el ítem de acortar se recomiendan esquemas de tratamiento para cada patología, priorizando los esquemas hipofraccionados cuando fue posible. CONCLUSIÓN: Se plantean estrategias para la gestión de los servicios de radioterapia con el objetivo de garantizar que los tratamientos de alta calidad para pacientes oncológicos sigan entregándose, pese a la crisis sanitaria ocasionada por COVID-19.

ABSTRACT

El presente artículo comprende una amplia y descriptiva revisión de la radiación desde su concepción básica, características, clasificación, fuentes, equipos, elementos radioactivos y los efectos biológicos en el ser humano. La diferencia entre radiación ionizante y no ionizante radica en la cantidad de energía del fotón individual y no en la cantidad de energía total. La radiación no ionizante se caracteriza por no contar con energía suficiente para convertir átomos o moléculas a iones, sin embargo es capaz de producir calor, útil en tratamientos fisiátricos y estéticos, pero con la posibilidad de producir quemaduras y otras lesiones que aún siguen en estudio. Entre las fuentes de radiación no ionizante tenemos la luz visible, el laser, la luz infrarroja, el microondas, y el teléfono móvil. Los diversos equipos de diagnóstico y tratamiento empleados en Medicina como rayos X, radioterapia, medicina nuclear, o en el caso de accidentes nucleares y guerras radiactivas, pueden generar radiaciones del tipo ionizante que rompen enlaces químicos, con el consecuente desarrollo de lesiones biológicas, en ocasiones graves


This article includes a broad and descriptive review of radiation from its basic conception, characteristics, classification, sources, equipment, radioactive elements and the biological effects on humans. The difference between ionizing and non-ionizing radiation lies in the amount of energy of the individual photon and not in the amount of total energy. Non-ionizing radiation is characterized by not having enough energy to convert atoms or molecules to ions; however they are capable of producing heat, useful in physiological and aesthetic treatments, with the possibility of producing burns and other injuries that are still under study. Among the non-ionizing radiation sources, we have visible light, laser, infrared light, microwave and mobile phone. The various diagnostic and treatment equipment used in Medicine such as X-rays, radiotherapy, nuclear medicine, or in the case of nuclear accidents and radioactive wars, can generate ionizing type radiation that breaks chemical bonds, with the consequent development of biological lesions that may be severe

ABSTRACT

The Human Genome Project and the continuing advances in DNA sequencing technology have ushered in a new era in genomic medicine. Successful translation of genomic medicine into clinical care will require that providers of this information are aware of the level of understanding, attitudes, perceived risks, benefits, and concerns of their patients. We used a mixed methods approach to conduct in-depth interviews with participants in the NCI-funded Breast Cancer Family Registry (BCFR). Our goal was to gain a better understanding of attitudes towards different types and amounts of genomic information, current interest in pursuing genomic testing, and perceived risks and benefits. We interviewed 32 women from the six BCFR sites in the USA, Canada, and Australia. In this sample of women with a personal or family history of breast cancer, we found high acknowledgement of the potential of genetics/genomics to improve their own health and that of their family members through lifestyle changes or alterations in their medical management. Respondents were more familiar with cancer genetics than the genetics of other diseases. Concerns about the testing itself included a potential sense of loss of control over health, feelings of guilt on passing on a mutation to a child, loss of privacy and confidentiality, questions about the test accuracy, and the potential uncertainty of the significance of test results. These data provide important insights into attitudes about the introduction of increasingly complex genetic testing, to inform interventions to prepare individuals for the introduction of this new technology into their clinical care.

ABSTRACT

Desde la década de los 80 se han realizado ensayos que permiten demostrar que la irradiación de la mama, luego de cirugía conservadora, es un componente fundamental en el manejo conservador del cáncer de mama en estadíos tempranos. La irradiación de la mama reduce el riesgo de recurrencia local, y previene la necesidad subsecuente de mastectomía. En la actualidad se han desarrollado estudios randomizados con la finalidad de evaluar el enfoque óptimo en la aplicación de las técnicas de radiación que se utilizan luego de cirugía conservadora de la mama. Estos ensayos evalúan parámetros muy importantes que incluyen esquemas de fraccionamiento, la utilización del boost. Los resultados de estos ensayos apoyan el uso de esquemas de fraccionamiento acelerado, y proponen evitar el boost de irradiación en casos seleccionados. Así mismo se evalúa la necesidad de irradiación nodal sólo en pacientes de alto riesgo que reciben irradiación de la mama en estadío temprano.


Since the 80s a series of trials have demonstrated that radiation after a conservative breast surgery is fundamental in early stage breast cancer. Radiation of the breast reduces the risk of local reoccurrences and prevents the need for a mastectomy. Radiotherapy reduces the risk of local recurrence and it prevents the subsequent necessity of mastectomy. At the moment randomized studies are being done to focus on the best radiation techniques used after conservative breast surgery. These studies evaluate very important parameters that include protocol of fractioning and the use of the boost. Also the need of nodal radiotherapy in high risk patients that had radiotherapy in early stages of breast cancer was evaluated.
