Preoperative chemoradiotherapy for oesophageal cancer: a systematic review and meta-analysis
2004
Background: The benefit of neoadjuvant chemoradiotherapy in oesophageal cancer has been extensively studied but data on survival are still equivocal. Objective: To assess the effectiveness of chemoradiotherapy followed by surgery in the reduction of mortality in patients with resectable oesophageal cancer. Methods: Computerised bibliographic searches of MEDLINE and CANCERLIT (1970–2002) were supplemented with hand searches of reference lists. Study selection: Studies were included if they were randomised controlled trials (RCTs) comparing preoperative chemoradiotherapy plus surgery with surgery alone, and if they included patients with resectable histologically proven oesophageal cancer wit…
Stereotactic Radiotherapy plus Radiosurgical Boost in the Treatment of Large Cerebral Arteriovenous Malformations
1993
Small sized AVMs respond well to stereotactic radiosurgery, while larger AVMs do poorly with stereotactic radiosurgery or stereotactic fractionated radiotherapy. A combination of both methods is proposed for the treatment of these larger lesions.
Bonnes pratiques de radiothérapie guidée par l’image
2015
Image-guided radiotherapy (IGRT) aims to take into account the anatomical variations occurring during the course of radiotherapy, by direct or indirect visualization of the target volume followed by a corrective action. The movements of the target, or at least the set-up errors are corrected by moving the treatment table, corresponding to the simplest and most validated IGRT modality in a standard practice. The deformations of the target volume and organs at risk are however much more common, and unfortunately much more complicated to consider, requiring multiple planning before or during the treatment, corresponding to the adaptive radiotherapy strategies. The planning target volume must b…
Melanoma of the oral mucosa with cerebral metastasis: a clinical case
2005
Summary Oral melanoma (OM) is an infrequent neoplasia making up less than 1% of all melanomas, and which exhibits a much more aggressive behaviour than those found on the skin. We present a case of OM located on the hard palate, vestibular alveolar gingiva of the maxilla, and upper lip in a 75-year-old patient who developed a distant metastasis on the left parietal lobe. The advanced stage of the disease contraindicated any surgical intervention and it was decided to carry out palliative radiotherapy, but the patient died before treatment.
Spinal metastases: Is stereotactic body radiation therapy supported by evidences?
2016
Stereotactic body radiotherapy (SBRT) is becoming widely adopted in the treatment of primary and secondary tumors. Spinal bone metastases are frequently discovered in cancer patients, and in the past have been usually treated with a palliative goal. Nevertheless, in some particular clinical settings, such as oligometastatic patients and/or those with a long life expectancy, spinal SBRT could be considered a valid therapeutic option to obtain long-lasting palliation and, when possible, with a curative goal. This review aims to summarize available clinical and dosimetric data of published studies about spinal SBRT.
Patient reported outcomes of symptoms and quality of life among cancer patients treated with palliative pelvic radiation: a pilot study
2011
Published version of an article from the journal: BMC Research Notes. Also available from the publisher: http://dx.doi.org/10.1186/1756-0500-4-252 BACKGROUND:There is limited high-quality research investigating the efficacy of palliative radiation (PPR) with regard to symptoms and quality of life (QOL) among cancer patients with pelvic soft tissue tumors. As a result, clinicians are left with mainly retrospective studies, without reliable data on which to base treatment decisions. As a first step of a subsequent analysis of PPR's efficacy, we aimed to determine whether it is feasible to prospectively measure symptoms and QOL among patients treated with PPR. A secondary aim was to explore pa…
The 2016 European Thyroid Association/European Group on Graves' Orbitopathy Guidelines for the Management of Graves' Orbitopathy
2015
Graves' orbitopathy (GO) is the main extrathyroidal manifestation of Graves' disease, though severe forms are rare. Management of GO is often suboptimal, largely because available treatments do not target pathogenic mech anisms of the disease. Treatment should rely on a thorough assessment of the activity and severity of GO and its impact on the patient's quality of life. Local measures (artificial tears, ointments and dark glasses) and control of risk factors for progression (smoking and thyroid dysfunction) are recommended for all patients. In mild GO, a watchful strategy is usually sufficient, but a 6-month course of selenium supplementation is effective in improving mild manifestations …
Técnicas reconstructivas tras amputación abdominoperineal extraelevadora del recto o exenteración pélvica: mallas, plastias y colgajos
2014
Perineal wound complications after abdomino-perineal rectal resection are frequent and clinically relevant for their impact on the length of hospitalization, costs, patients' quality of life and oncologic results. With the diffusion of the preoperative radiotherapy and the gradual shift to the extra-elevator technique, the perineal morbidity rate has increased. Many series describing different techniques of primary closure of the perineal defect have been published, but high-quality clinical studies, indicating which is the best option, are missing. A biologic mesh, associated if possible to an omentoplasty, seems to be sufficient to close the perineal defect after extra-elevator abdomino-p…
Analysis of cardiac and pulmonary complication probabilities after radiation therapy for patients with early-stage breast cancer
2009
Objective. The purpose of this study was to evaluate the radiobiological implications of clinical use of respiratory-gated techniques for postoperative radiation therapy of early-stage left-sided breast cancer after breast-conserving surgery. Material and methods. Radiation therapy treatment plans of 80 patients with early-stage breast cancer (stage I–II), receiving whole breast irradiation after breast-conserving therapy, were analyzed. The control group consisting of 47 patients received standard radiation therapy, and the respiratory-gated group consisting of 33 patients received deep inspiration-gated radiation therapy. Normal tissue complication probabilities (NTCP) for cardiac mortali…
The impact of radiotherapy on survival in resectable gastric carcinoma: A meta-analysis of literature data.
2007
Summary Background The benefit of external radiotherapy for gastric carcinoma has been extensively studied, but data on survival are still equivocal. Objective To assess the effectiveness of surgery combined with preoperative radiotherapy or postoperative chemoradiotherapy in the reduction of all-cause mortality in patients with resectable gastric carcinoma. Methods Computerised bibliographic searches of MEDLINE and CANCERLIT (1970–2006) were supplemented with hand searches of reference lists. Study selection Studies were included if they were randomised controlled trials (RCTs) comparing mortality of surgery combined with preoperative radiotherapy or postoperative chemoradiotherapy to surg…
