A male patient, aged 33, was treated at the Clinic for Oncology, Hematology and Radiotherapy at the University Clinical Center, Tuzla, with the diagnosis of diffuse large B-cell lymphoma. Conformal radiotherapy was conducted on the region of the epipharynx, oropharynx and lymph nodes of the neck on both sides (1). The target volume included the following: the clinical target volume (CTV) of the...

OBJECTIVE To observe clinical effects of three-dimensional conformal radiotherapy combined with Tegafur Gimeracil Oteracil Potassium chemotherapy in the treatment of patients with recurrent esophagus cancer. METHODS One hundred and twelve senile patients who suffered from esophagus cancer were selected and randomly divided into two groups, namely, observation group (56 cases) and control grou...

BACKGROUND According to the literature, performance status, stage-tumor dimension and nodal status, weight loss, were the most important prognostic factors for survival in patients with locally advanced non-small cell lung cancer. AIM To evaluate the treatment results and the prognostic variables in our patients treated with sequential and concurrent chemoradiotherapy. MATERIAL AND METHODS ...

Background: Identify the optimal technique of radiotherapy for patients with high grade glioma. Our initial year of experience with RapidArc radiation therapy. Materials and Methods: Planning CT scans of 50 patients with grade IV glioma were reviewed and three plan sets by 3D Conformal Radiotherapy (3DCRT), Intensity Modulated Radiotherapy (IMRT) and Rapid Arc (RA) were generated and the plans ...

The appropriate application of 3-D conformal radiotherapy, intensity modulated radiotherapy or image guided radiotherapy for patients undergoing post-operative radiotherapy for prostate cancer requires a standardisation of the target volume definition and delineation as well as standardisation of the clinical quality assurance procedures. Recommendations for this are presented on behalf of the ...

OBJECTIVE Assess the results of salvage conformal radiotherapy in patients with biochemical failure after radical prostatectomy and identify prognostic factors for biochemical recurrence and toxicity of the treatment. MATERIALS AND METHODS From June 1998 to November 2001, 35 patients were submitted to conformal radiotherapy for PSA > or = 0.2 ng/mL in progression after radical prostatectomy a...

Introduction: Modern radiotherapy (RT) techniques allow a highly precise deposition of the radiation dose in tumor. So, high conformal tumor doses can be reached while sparing critical organs at risk. Materials and Methods: This study was conducted in three phases. In the first phase; Fourteen patients with primary or recurrent prostate cancer receive Gallium-...

Introduction: Radiotherapy is a common treatment modality for patients with head and neck malignancies. As the nose lies within the field of radiotherapy of the head and neck, the olfactory fibers and olfactory receptors may be affected by radiation. The aim of this study was to evaluate changes in olfactory threshold in patients with head and neck malignancies who have received radiation to th...

ID: 13564 Title: A novel conformal arc technique for postoperative whole pelvic radiotherapy of endometrial cancer Introduction: Conventional whole pelvic radiotherapy (WPRT) with three-dimensional conformal radiotherapy (3D-CRT) exposes most of the contents of the true pelvis to the prescribed dose. Intensity-modulated radiation therapy (IMRT) provides more conformal dose distribution and bett...
