RESUMO

Purpose: The aim of this phase II study was to evaluate the activity and safety of the combination of cisplatin and vinorelbine with thoracic radiotherapy in unresectable locally advanced stage III non-small cell lung cancer (NSCLC). The primary endpoint was the objective response rate (ORR). Secondary objectives included toxicity profile, progression-free survival (PFS), and overall survival (OS). Materials and methods: A total of 48 NSCLC patients were enrolled (median age 60 years, 52% stage IIIA and 48% stage IIIB, 52% adenocarcinoma). Patients received three cycles of chemotherapy every 21 days [intravenous cisplatin 80 mg/m2 and intravenous vinorelbine 25 mg/m2 on day 1 and oral vinorelbine on day 8 (60 mg/m2)] concurrent with radiotherapy (66 Gy, administered at 1.8 Gy per day, five consecutive days per week). Results: ORR was 79.2% (72.9% showing partial response and 6.3% showing complete response). With a median follow-up of 20.7 months, median PFS was 12 months and median OS was 36 months. Grade 3/4 toxicities were: neutropenia (14.5%), anaemia (6.2%), vomiting (2%), and oesophagitis (4.2%). No toxic deaths were reported. Conclusion: This combined regimen shows efficacy and a manageable safety profile. PFS and OS outcomes are encouraging and warrant further research

RESUMO

INTRODUCTION: Arteriovenous malformations are abnormal communications between arteries and veins. Treatment can consist in surgery, embolisation and/or radiosurgery. AIM: To assess the influence of radiosurgery on the risk of bleeding and related factors. PATIENTS AND METHODS: Retrospective study of 79 patients who were treated with a 6 MV linear accelerator. Clinical, morphological and dosimetric parameters were collected and a statistical analysis was performed to investigate their relationship with bleeding during the latency period. RESULTS: The mean age was 33.7 years, and 56% of patients were females. The mean volume was 6.16 cm(3). Bleeding occurred before treatment in 52.6% of cases. Altogether 25% had been embolised and 7.6% had been treated earlier using radiosurgery. Six patients suffered a haemorrhage after treatment. Bleeding occurred in 21% of those who had undergone embolisation versus 3.6% in non-embolised individuals (p < 0.02). Bleeding occurred in 33.3% of those who had been treated radiosurgically on more than one occasion, and only 5.7% if they were treated just once (p = 0.02). Bleeding took place in 28.6% of lesions above 10 cm(3) and in 3.2% when they were smaller (p < 0.01). Bleeding occurred in 16.1% of patients if they received less than 17 Gy, and in 2.22% if they received 17 or more (p < 0.01). All haemorrhages took place in treatments with more than one isocentre (p < 0.01) and with a higher homogeneity index (p < 0.01). CONCLUSIONS: Radiosurgery does not modify the risk of bleeding. The factors associated to higher percentages of bleeding are also related to poorer closure outcomes and longer latency periods.

RESUMO

Introducción. Las malformaciones arteriovenosas son comunicaciones anómalas entre arterias y venas. El tratamiento puede realizarse mediante cirugía, embolización y/o radiocirugía. Objetivo. Evaluar la influencia de la radiocirugíasobre el riesgo de sangrado y los factores relacionados con éste. Pacientes y métodos. Estudio retrospectivo de 79 pacientes tratados con acelerador lineal de 6 MV. Se recogieron parámetros clínicos, morfológicos y dosimétricos, analizando estadísticamentesu relación con el sangrado durante el período de latencia. Resultados. La edad media fue de 33,7 años, y el 56%fueron mujeres. El volumen medio fue de 6,16 cm3. El 52,6% sangró antes del tratamiento. El 25% había sido embolizado y el 7,6% había recibido radiocirugía previamente. Seis pacientes sufrieron hemorragia tras el tratamiento. Sangró el 21% de los embolizados, frente al 3,6% de los no embolizados (p = 0,02). Entre los tratados con más de una radiocirugía sangró el33,3%, y sólo el 5,7% si se trataron una sola vez (p = 0,02). Sangró el 28,6% de las lesiones mayores de 10 cm3 y el 3,2% de las menores (p < 0,01). Sangró el 16,1% si recibieron menos de 17 Gy, y el 2,22% si recibieron 17 o más (p < 0,01). Todas las hemorragias se produjeron en tratamientos con más de un isocentro (p < 0,01) y con índice de homogeneidad más alto (p < 0,01). Conclusiones. La radiocirugía no modifica el riesgo de sangrado. Los factores asociados con mayores porcentajes de hemorragia se relacionan también con peores resultados de cierre y períodos de latencia más prolongados

RESUMO

El carcinoma epidermoide primario de mama esuna entidad muy poco frecuente. Típicamente sepresenta como un tumor cístico en la mama de grantamaño y evolución rápida. (También se caracterizapor diseminación a distancia y escasa afectaciónmetastásica en ganglios). En la mayoría de los casos,los receptores hormonales son negativos y loshallazgos radiológicos son inespecíficos. Los tratamientosdescritos en la literatura consisten en lacombinación de cirugía, quimioterapia y radioterapia


Breast primary squamous carcinoma is an infrequententity. It appears typically as a voluminousbreast cystic tumour of rapid evolution. It is characteristicthe development of a systemic disseminationgenerally in the absence of regional lymph nodemetastases. In most cases hormone receptors arelacking, and radiological findings are not specific.The treatments described in the medical literatureconsist of a combination of surgery, chemotherapyand radiotherapy

RESUMO

Objetivo. Investigar y contrastar la efectividad de los diferentes linfofármacos utilizados en el tratamiento del linfedema del miembro superior, secundario a radioterapia y/o cirugía por cáncer de mama. Estrategia de búsqueda. Se ha realizado una búsqueda en las bases de datos IME, MD-CONSULT, MEDSCAPE, EXCERPTA MEDICA, OVID, MEDLINE, COCHRANE DATABASE OF SYSTEMATIC REWIEWS, CINAHL, CANCERLIT y Sociedades Científicas relacionadas con el manejo del linfedema desde 1978 hasta junio de 2004. No hemos seguido ningún protocolo de búsqueda en las bases más extensas por temor a perder información, ni hemos contado con expertos en la estrategia de búsqueda, que ha sido muy laboriosa con introducción de numerosos sinónimos y probables. Selección de artículos. Encontramos 26 trabajos que evaluaban la efectividad de cualquier modalidad de tratamiento farmacológico. Para facilitar su comprensión y lectura se han clasificado en tres grandes grupos en relación con el diseño del estudio, elaborando tablas que recogen las características metodológicas y análisis de datos de cada uno de ellos. En los ensayos clínicos se especifica si hay conflicto de intereses con la industria farmacéutica y/o promotores. Selección de resultados. Se han analizado y seleccionado en función de la calidad metodológica, diseño, tipo de intervención y resultados principales. Síntesis de resultados. Existen muy pocos estudios con suficiente calidad metodológica para extraer conclusiones y sus resultados son contradictorios. Conclusiones. En esta revisión sistemática de la literatura científica no encontramos pruebas fehacientes para recomendar el uso de los linfofármacos en el tratamiento del linfedema postmastectomía


Objective. Investigate and compare the effectiveness of the different lymphodrugs used in the treatment of lymphedema of the upper limb, secondary to radiotherapy and/or surgery due to breast cancer. Search strategy. A search was performed in the following databases IME, MD-CONSULT, MEDSCAPE, EXCERPTA MEDICA, OVID, MEDLINE, COCHRANE DATABASE OF SYSTEMATIC REWIEWS, CINAHL, CANCERLIT and Scientific Societies related with the management of lymphedema from 1978 to June 2004. We have not followed any search protocol in the most extensive bases for fear of losing information nor have we counted on experts in search strategy, which was very arduous with the introduction of many synonyms and probable synonyms. Article selection. We found 26 papers that evaluated effectivity of any drug treatment modality. To facilitate its understanding and reading, they were classified into three large groups in relationship with the study design, elaborating tables that collect the methodological characteristics and data analysis of each one of them. It is specified in the clinical trials if there is a conflict of interest with the pharmaceutical industry and/or sponsors. Result selection. They were analyzed and selected based on methodology quality, design, type of intervention and main results. Result synthesis. There are very few studies with sufficient methodological quality to draw conclusions and their results are contradictory. Conclusions. There is no clear evidence in this systematic review of the scientific literature to recommend the use of lymphodrugs in the treatment of postmastectomy lymphedema

RESUMO

El incremento de las indicaciones de la Radioterapia (RT) como tratamiento de primera línea en determinadosprocesos oncológicos, la necesidad de aumentar la intensidad de dosis para un adecuadocontrol local y una mayor sensibilización social del valor de la Calidad de Vida de los pacientes,han impulsado la búsqueda de tratamientos de soporte para prevenir y tratar sus complicaciones deuna forma más eficaz y a un coste razonable.La Oxigenoterapia Hiperbárica (OHB), técnica introducida hace unos 80 años en el tratamiento delos “accidentes de buceo”, también ha sido utilizada en procesos relacionados con isquemia/necrosis.Estos antecedentes han supuesto que los investigadores y clínicos que tratamos a los pacientescon cáncer, hayamos abierto una línea de trabajo de la cual podría beneficiarse un grupo de pacientesseleccionado.En esta revisión describimos las bases físicas, técnicas y fisiopatológicas en relación con la Radioterapia(RT). Además hacemos una revisión básica de las indicaciones de la OHB, en función del áreaanatómica afecta


The increasing indications of radiation therapy (RT) as treatment of choice in specific oncologicalprocesses, the need to increase the intensity for an adequate tumor control, and a greater socialsensitivity about the value of the patients quality of life, impelled the search of supportive treatmentsto prevent and treat the radiotherapy complications in a more effective manner, and at a reasonablecost.The technique of the hyperbaric oxygen (HBO) therapy was introduced 80 years ago for thetreatment of diving accidents, and has also been used in processes related to ischemia/necrosis.These background drove the researchers and clinicians treating cancer patients to open a workingline that could benefit a group of selected patients.We describe in this review the physical, technical and physiological bases of radiation therapy(RT). We also make a basic review of the indications of HBO therapy according to the affectedanatomical area

RESUMO

La Cronobiología es la disciplina médica cuyo campo de acción es el estudio de los eventos biológicos en relación con el tiempo. En este trabajo hacemos una revisión bibliográfica sobre los conceptos que definen la Cronobiología como disciplina médica desde sus orígenes en el tiempo hasta su aplicación actual, tanto en estudios experimentales como clínicos, en relación con el tratamiento del cáncer. El objetivo principal de este trabajo es definir los conceptos que agrupan a esta disciplina biológica, así como las herramientas metodológicas que utiliza para su desarrollo y la difusión de las mismas en la práctica clínica diaria de la Oncología (AU)

RESUMO

Propósito: El uso de la quimioterapia adyuvante según esquema Levamisol y 5-Fluoruracilo en el estadio C del carcinoma de colon, sigue siendo uno de los protocolos estándar utilizados. Asociado a esto se han publicado algunos casos, etiquetados de Leucoencefalopatía Multifocal Inflamatoria. Material y métodos: Presentamos el caso de una paciente, que tuvo un episodio de Leucoencefalopatía Multifocal Inflamatoria, asociado a la utilización del 5 FU-Levamisol, que inicialmente fue interpretado como un cuadro de enfermedad metastásica en el SNC (sistema nervioso central).Resultados: Describimos el cuadro clínico, metodología diagnóstica, tratamiento recibido por la paciente, y su situación clínica actual. Conclusiones: Analizamos las consecuencias de nuestra actuación médica y una posible hipótesis patogénica (AU)
