PURPOSE To evaluate the normal tissue reactions and loco-regional control rates (LRC) in patients treated with 7-days-a-week postoperative continuous irradiation (p-CAIR) compared to conventionally fractionated 5-days-a-week postoperative radiotherapy (CF). MATERIALS/METHODS Between 2001 and 2004, 279 patients with high-risk squamous cell cancer of the(More)
PURPOSE To evaluate the dose-response relationship for a wide range of doses lower than 50 Gy delivered to the hilar and mediastinal lymph node stations from incidental irradiation in 220 patients with non-small-cell lung cancer (NSCLC) treated with three-dimensional conformal radiotherapy. The endpoint was isolated nodal recurrence (INR) in stations that(More)
BACKGROUND Colorectal cancer, one of the most aggressive cancers, occurs with a high incidence in most countries. The usual treatment is surgery and subsequent chemotherapy and radiotherapy. Cancer development and progression is dictated by series of alterations in genes such as tumor suppressor genes, DNA repair genes, oncogenes and others. In colorectal(More)
PURPOSE To evaluate the feasibility and preliminary results of intraoperative radiotherapy (IORT) with low-energy photons as a boost in patients with early-stage oral cancer with the indications for postoperative radiotherapy. PATIENTS AND METHODS Between 2003 and 2006, 16 patients with early-stage cancer of mobile tongue (n = 10 [63%]) or floor of the(More)
The retrospective chart review of 110 patients with T2 supraglottic cancer who underwent radiotherapy was performed to correlate tumor volume with other prognostic factors and to analyze its impact on treatment results. Patients with involved nodes, poor histopathological tumor differentiation, or hemoglobin concentration ≤ 14.3 g/dl had significantly(More)
Heterotopic ossification is a common complication of hip arthroplasty (35-57%) and multifragmental acetabular fractures (50-70%). Due to complication level and cost of surgery in this region, more popular become methods of heterotopic ossification prevention as well as non-steroid anti inflammatory drug intake and radiotherapy (approximately 90%(More)
The material consisted of 18 patients, a pilot group of randomised study regarding radiotherapy of advanced head and neck cancer with massive lymph nodes metastases using accelerated, hyperfractionated, split-course scheme (CHA-CHA). Patients were irradiated twice a day with 6 hours gap using fraction dose of 1.6 Gy up to dose of 32 Gy. The same course of(More)
PURPOSE The purpose of this investigation was to evaluate the quality of life, measured in LENT-SOMA and DISCHE scale, of patients with xerostomia as late irradiation injury. MATERIALS AND METHODS 45 head and neck cancer patients were radically irradiated receiving doses from 48 Gy to 76.8 Gy (mean: 65.1 Gy) on PTV. Patients received doses from 48 to 76(More)
For over 2 years, we have had access to latest generation apparatus and software for planning and stereotactic treatment as well as for x-rays treatment. Until now, we have carried out over 100 procedures. These included 52 stereotactic biopsies of neoplasms, some of them located within the structures of the posterior fossa. In this report, we have(More)
