Cosmetic assessment in brachytherapy (interventional radiotherapy) for breast cancer: A multidisciplinary review.

PURPOSE: This review was to focus on breast brachytherapy cosmetic assessment methods state of the art and to define the advantages and disadvantages related to. METHODS AND MATERIALS: We conducted a literature review of the major experience on breast brachytherapy cosmetic assessment methods in several databases (PubMed, Scopus, and Google Scholar databases). To identify the relevant works, a task force screened citations at title and abstract level to identify potentially relevant paper. An expert board reviewed and approved the text. The assessment systems were classified into three main groups: (1) the Oncological Toxicity Scales, (2) the Independent Patients Perspective Measures, (3) the Patient-Related Outcome Measures. Each cosmetic assessment method was evaluated following six parameters: (1) anatomical site, (2) advantages, (3) disadvantages, (4) subjective/objective, (5) quantitative/qualitative, (6) computers or pictures needs. RESULTS: Eleven assessment methods were selected. Three methods were classified as Oncological Toxicity Scale, six in the Independent Patients Perspective Measures classification, and two as Patient-Related Outcome Measures. Six methods are subjective, while eight are objective. Four systems are classified as quantitative, four as qualitative while three both. Five systems need informatics support. Moreover, each method was discussed individually reporting the main characteristics and peculiarities. CONCLUSIONS: Cosmesis is one major end point for the patient who has a malignancy of low lethal potential. In modern personalized medicine, there is a need for standardized cosmetic outcome assessments to analyze and compare the results of treatments. No gold standard methods currently exist. The result of this review is to summarize the various cosmesis methods, defining the strengths and weaknesses of each one and giving a line in research and clinical practice.

GEC-ESTRO ACROP recommendations in skin brachytherapy.

PURPOSE: The aim of this publication is to compile available literature data and expert experience regarding skin brachytherapy (BT) in order to produce general recommendations on behalf of the GEC-ESTRO Group. METHODS: We have done an exhaustive review of published articles to look for general recommendations. RESULTS: Randomized controlled trials, systemic reviews and meta-analysis are lacking in literature and there is wide variety of prescription techniques successfully used across the radiotherapy centers. BT can be delivered as superficial application (also called contact BT or plesiotherapy) or as interstitial for tumours thicker than 5 mm within any surface, including very irregular. In selected cases, particularly in tumours located within curved surfaces, BT can be advantageous modality from dosimetric and planning point of view when compared to external beam radiotherapy. The general rule in skin BT is that the smaller the target volume, the highest dose per fraction and the shortest overall length of treatment can be used. CONCLUSION: Skin cancer incidence is rising worldwide. BT offers an effective non-invasive or minimally invasive and relative short treatment that particularly appeals to elder and frail population.

Tratamiento no quirúrgico del schwannoma vestibular / Non surgical treatment of vestibular schwannoma

Introducción y objetivos: Valorar los resultados de control local y complicaciones en el tratamiento del schwannoma vestibular tratado con radiaciones. Métodos: Estudio retrospectivo de 194 pacientes diagnosticados de schwannoma vestibular, tratados de manera consecutiva bien con observación o bien con radiaciones (bien radiocirugía o radioterapia esterotáctica fraccionada) de 1997 a 2012. Analizamos el control local de los tumores, así como de las complicaciones secundarias al tratamiento con radiocirugía. Resultados: El 68% (132 tumores) son inferiores a 2 cm es decir grado I-II de la clasificación de Koos, 22 pacientes (13%) con tumores grandes grado IV, el resto (40 pacientes) son grado III. Los tumores relacionados con la neurofibromatosis (NF2) representan el 3,6% (6 tumores en 4 pacientes). El control tumoral para los pacientes tratados con radiaciones es del 97% a 5 años, con un seguimiento mediano de 80,4 meses. Para los tumores grandes el control local es del 91% a 5 años. La supervivencia libre de complicaciones crónicas es del 89% a 5 años. De los 50 tumores a los que se realizó seguimiento, 28 (58%) continúan en seguimiento al no haberse objetivado crecimiento alguno. Conclusiones: La radiación y el seguimiento con RM, dentro de un enfoque multidisciplinar, es una alternativa a la cirugía en el tratamiento del schwannoma vestibular, con un bajo nivel de complicaciones (AU)

Introduction and objectives: To evaluate the results of local control and complications in the treatment of vestibular schwannoma treated with radiation. Methods: A retrospective study of 194 patients diagnosed with vestibular schwannoma, treated consecutively with radiation (either stereotactic radiosurgery or fractionated radiotherapy) from 1997 to 2012. We analyze the local control of tumors, as well as secondary complications to treatment with radiation. Results: A total of 132 (68%) tumors 68% are grade I-II tumors of the Koos classification, 40 (19%) are grade III, and 22 (13%) are grade IV. The tumors associated with neurofibromatosis (NF2), are 3.6% (6 tumors in 4 patients). The tumor control for the overall serie is 97% at 5 years, with a median follow-up of 80.4 months. For large tumors the local control is 91% at 5 years. Free survival of chronic complications is 89% at 5 years. Aditionally, 50 tumors were subjected to regular follow-up with MRI without treatment, and 28 (58%) did not experienced tumor growth. Conclusions: Radiation and follow up with MRI, are an alternative to surgery in the treatment of vestibular schwannoma, with a low level of complications inside of multidisciplinary approach (AU)
