RESUMEN

BACKGROUND: Evaluate the safety, toxicity and efficacy of an institutional-simplified SBRT protocol with two short SBRT regimens (three or five fractions) for the treatment of lung cancer and oligometastases, according to the volume and localization of tumours. METHODS: Patients with stage I (T1 or T2) non-small cell lung cancer or lung oligometastases were treated from August 2011 to October 2015. Patients were required to be considered medically inoperable and were discussed in a multidisciplinary team. RESULTS: 100 patients were analysed, 59 had a peripheral location (P), and 41 a central location (C).All patients finished their SBRT course without interruptions related to acute toxicity. The most frequent acute toxicity was grade 1 asthenia, only one patient developed grade 3 toxicity (pneumonitis) and there were no grade 4 or 5 acute toxicities. Three asymptomatic radiation-induced rib fractures were identified, the 1 and 2-year rib fracture-free survival were 97% and 94%, respectively. Two-year progression-free survival and 2-year overall survival of all patients were 52% and 70%, respectively, with a median PFS and OS of 26 and 43 months. Survival free of local progression (SFLP) at 2 years was 89%. A higher PFS in primary lung cancer compared with metastatic tumours was observed, with a median of 35 months with 19 months (p = 0.01). However, no statistical difference was observed in terms of OS between both diseases. CONCLUSIONS: SBRT in lung cancer with three sessions for peripheral tumours and five sessions for central tumours may be safely delivered, with low morbidity.

RESUMEN

INTRODUCTION: Head and neck cancer recurrence is a therapeutic challenge due to the anatomical and functional constraints of the head and neck area. Stereotactic body radiotherapy (SBRT) is a high-precision technique of radiotherapy that consists of delivering a high ablative biological dose in 1-5 high-dose fractions, requiring a very high precision of the radiotherapy process with potential application in this clinical setting METHODS: Different studies that investigate the role of SBRT in the treatment of recurrent head and neck cancer have been reviewed. Indications to properly select patients for this treatment are presented. RESULTS: Retrospective studies and phase I-II trials with selected patients have shown low to moderate toxicity, with an efficacy at least similar to that of treatment with combinations of radiotherapy and chemotherapy. In selected patients, SBRT is a treatment option for recurrent head and neck cancer with low toxicity. DISCUSSION: New prospective studies should clarify data regarding the efficacy and toxicity of SBRT in head and neck cancer recurrence.

RESUMEN

Objetivo. Conocer los factores que determinan la recuperación funcional tras haber sufrido una fractura de cadera. Método. Se ha realizado un estudio de cohortes sobre 333 fracturas de cadera en pacientes mayores de 65 años, que ingresaron en el Hospital Regional Universitario Carlos Haya entre febrero de 2004 y febrero de 2005. Hemos recogido datos epidemiológicos, clínicos y de actividad funcional de dichos pacientes mediante la aplicación de escalas de uso generalizado, para conocer la funcionalidad que presentan antes de la fractura y en el seguimiento posterior, mediante entrevistas telefónicas a los 6 meses tras la misma. Resultados. A los 6 meses de la fractura los factores pronósticos de incapacidad funcional son la edad, el hecho de estar institucionalizado, presentar una mala funcionalidad previa a la fractura, ser dependiente para las actividades básicas de la vida diaria y la circunstancia de haber presentado una fractura extracapsular o que haya sido sometida a osteosíntesis. Conclusiones. Podemos conocer el pronóstico del paciente con fractura de cadera al ingreso, el uso de sistemas de fijación extramedular no ha mostrado buenos resultados en nuestro trabajo frente a la artroplastia. La osteosíntesis intramedular (usada únicamente en 5 casos) junto a un inicio precoz de la rehabilitación podrían mejorar los resultados funcionales de estos pacientes, ya que ha demostrado ser superior en las fracturas pertrocantéreas inestables y en las subtrocantéreas (AU)

Aim. To determine the factors that affect functional recovery after a hip fracture. Methods. A study was conducted on a cohort of 333 patients aged 65 years or over with hip fractures who were admitted to Carlos Haya hospital between February 2004 and February 2005. Epidemiological, clinical and functional activity data were recorded by applying generally used scales to determine the patients’ functionality before and after the fracture, by means of telephone interviews 6 months after the fracture. Results. Prognostic factors of functional incapacity 6 months after the fracture were age, being institutionalised, having poor functionality before the fracture, being dependent for basic activities of daily living and having had an extracapsular fracture or undergoing osteosynthesis. Conclusions. It is possible to determine the prognosis of a hip fracture patient on admission. The use of extramedullary fixation systems failed to show good results compared with arthroplasty. Intramedullary osteosynthesis (used only in 5 patients), and an early start of rehabilitation could improve the functional results of these patients. In fact, intramedullary nailing has demonstrated better outcomes in unstable trochanteric and subtrochanteric femoral fractures vs Dynamic Screw and Plate (AU)
