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)
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)
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 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)
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. Between 2003 and 2006, 16 patients with early-stage cancer of mobile tongue (n = 10 [63%]) or floor of the mouth (n = 6 [37%]) treated at(More)
BACKGROUND/AIM Scarce data exist concerning the long-term effect of renal balloon angioplasty (PTRA) enhanced by intravascular gamma-brachytherapy (IVBT) in patients with renovascular hypertension. The aim of this randomized study was to evaluate long-term outcome after PTRA with IVBT in patients with renal artery stenosis. PATIENTS AND METHODS 71(More)
The physician-patient relationship is a significant component of the treatment strategy. Communication constitutes perhaps the most important process in medicine. Among various aspects of the direct relationship between the physician and the patient, conversations with the patient are among the most important. It is the duty of the physician to supply 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)
PURPOSE To assess the toxicity and the efficacy of adjuvant radio-chemotherapy in patients with high-risk gastric cancer. METHODS AND MATERIALS Patients with adenocarcinoma of the stomach were enrolled into the study from April 1999 to December 2000. There were 15 females and 27 males, 33 to 69 years old (median 52). There were following inclusion(More)
