the present retrospective study was designed to analyze factors with prognostic values a) within, and b) significantly associated with, short-term (12months or less) and long-term (more than 24 months) survival times, i n 72 consecutive patients treated for malignant gliomas. among 41 (57%) short-term surviving patients, the absence of both aphasia and motor deficit (as initial presenting sympt...

PURPOSE To investigate tumor interstitial fluid pressure as a prognostic factor for recurrence-free survival in patients with cervical cancer following radiation therapy. EXPERIMENTAL DESIGN Tumor interstitial fluid pressure was measured in 55 cervical cancer patients who received radiation therapy between August 1998 and September 2002. Interstitial fluid pressure measurements were made befo...

Extra renal extra cranial malignant rhobdoid tumors (MRT) are rare, frequently lethal and affect mostly children. No definite treatment has been made and the role of radiation therapy is poorly defined. This report explains a 14 year old girl with MRT in her neck soft tissue. She is alive with no evidence of disease 18 months after diagnosis. Through the experience with this case, we suggested...

PURPOSE We assessed survival after radical prostatectomy, intensity modulated radiation therapy or conformal radiation therapy vs no local therapy for metastatic prostate cancer adjusting for patient comorbidity, androgen deprivation therapy and other factors. MATERIALS AND METHODS We identified men 66 years old or older with metastatic prostate cancer treated with radical prostatectomy, inte...

Background: Three-dimensional conformal radiotherapy (3D-CRT) and intensity-modulated radiotherapy (IMRT) techniques are used for the treatment of patients with laryngeal cancer. Objective: This study aimed to investigate the effects of these 2 treatment techniques on the planning target volume (PTV) (laryngeal cancer), dose homogeneity, dose of organs at...

Introduction: In the present study, AS1411 aptamer conjugated gold nanoclusters (GNCs) have been introduced as a targeted radiosensitizer for enhancing megavoltage radiation therapy efficacy. RT has identified as an effective therapeutic modality for many different types of solid tumors. However, equal radiation beams absorption by tumor and surrounding healthy tissues is still...

Objective(s): Radiation therapy for breast cancer can induce myocardial capillary injury and increase cardiovascular morbidity and mortality. A prospective cohort was conducted to study the prevalence of myocardial perfusion abnormalities following radiation therapy of left-sided breast cancer patients as compared to those with right–sided cancer. Methods: To minimize potential confounding fact...

PURPOSE In the United States, adjuvant radiation therapy is currently recommended for most patients with rectal cancer. We conducted this population-based study to evaluate the rate of radiation therapy and the factors affecting its delivery. METHODS We used the Surveillance Epidemiology and End Results database to assess treatment of patients with nonmetastatic rectal cancer diagnosed over a...

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...
