Application of a single fraction of parallel opposed GRID beams as a means of increasing the efficiency of radiation delivery to deep-seated tumors has been investigated. This evaluation was performed by measurement of dosimetric characteristics of the GRID radiation field in parallel opposed and single beam geometry. The limitations of the parallel opposed technique in terms of field size and ...
BACKGROUND In isolated limb perfusion (ILP) with tumor necrosis factor-alpha (TNFalpha) and interferon (IFN)-gamma, pioneered by Lienard and Lejenne in 1988, TNFalpha was empirically employed at a dosage (3-4 mg) ten times higher than the systemic maximum tolerable dose (MTD). We previously conducted a phase I/II study in 20 patients with in-transit melanoma metastases, using a combination of m...
The tumor lysis syndrome (TLS), characterized by hyperkalemia, hyperuricemia, hyperphosphatemia and secondary hypocalcemia, is a consequence of treatmentinduced or spontaneous tumor cell death. It usually occurs a few hours to a few days after commencing cytotoxic chemotherapy for tumors with a high percentage of proliferating and drug-sensitive cells. Cell death leads to the release of potassi...
PURPOSE To evaluate the clinical efficacy and toxicity of stereotactic body radiation therapy (SBRT) using extracranial gamma knife in patients with mainly bulky inoperable early stage non-small cell lung carcinoma (NSCLC). MATERIALS AND METHODS A total of 43 medically inoperable patients with mainly bulky Stage I/II NSCLC received SBRT using gamma knife were reviewed. The fraction dose and t...
Lung cancer is a leading cause of cancer-related deaths in several nations. Epidemiological studies have indicated that 85% of all lung cancer deaths and 30% of all cancer deaths in the U.S. are associated with tobacco smoking. Various chemicals in tobacco smoke are thought to react with DNA and to ultimately yield heritable mutations. In an effort to understand the molecular mechanisms involve...
Endometrial stromal tumors are extremely rare uterine malignancy, mainly among young females. Herein, we report a case of low-grade endometrial tumor in 19-year-old women who presented with the non-specific symptoms lower abdominal pain, swelling and vaginal bleeding similar to leiomyoma. Ultrasound finding showed bulky uterus multiple fibroid degenerative changes. Contrast enhanced computed to...
طی دهه اخیر، پردازش تنک سیگنال ها به عنوان ابزاری قدرتمند و جایگزینی کارا برای تبدیل های کلاسیک، توجه زیادی را به خود جلب کرده است. استفاده از نمایش تنک سیگنال ها در مسائل طبقه بندی نیز نتایج موفقیت آمیزی به همراه داشته است. با این حال، کیفیت عملکرد این طبقه بندی کننده ها در شرایط سخت، از جمله در مواردی که داده های هر طبقه تنوع زیادی داشته و یا ابعاد داده ها در مقایسه با تعداد داده های آموزشی ز...
