BACKGROUND Identification of pretreatment prognostic factors influencing overall survival (OS) in locally advanced squamous cell carcinoma of the head and neck is an important issue in head and neck oncology. METHODS A total of 289 patients were treated with standard fraction or hyperfractionated radiation therapy with or without concurrent low-dose daily(More)
Purpose: Feasibility, antitumor activity and toxicity of accelerated hyperfractionated radiation therapy (Acc Hfx RT) and concurrent carboplatin/etoposide (CBDCA/VP 16) chemotherapy were investigated in patients with malignant glioma. Material and methods: Seventy-nine patients with either glioblastoma multiforme (GBM) (n = 61) or anaplastic astrocytome(More)
The omission of standards for renal length in infants younger than 1 year may result in a statistically significant increase in the frequency of “spurious” nephromegaly. Nonetheless, there are only a few reports specifically dealing with normal kidney dimensions in infants. Based on sonographic assessments performed on a sample of 992 healthy infants,(More)
Purpose: To investigate feasibility, toxicity and antitumor activity of combined surgery, postoperative radiation therapy (RT) and adjuvant chemotherapy (CHT) in adult patients with pure anaplastic oligodendroglioma (PAO) or mixed anaplastic oligoastrocytoma (MAO). Methods: Between January 1988, and June 1993, 23 patients entered into a phase II study.(More)
OBJECTIVE Nerve transfers in cases of brachial plexus traction injuries with avulsion of spinal nerve roots or irreparable proximal lesions of spinal nerves have been attempted using a variety of donor nerves. The purpose of this study was to analyze the results of nerve transfers to the musculocutaneous and axillary nerves, using collateral branches of the(More)
There are only a few reports on the use of thoracodorsal nerve (TDN) transfer to the musculocutaneous or axillary nerves in cases of directly irreparable brachial plexus injuries. In this study, we analysed outcome and time-course of recovery in correlation with recipient nerves and type of nerve transfer (isolated or in combination with other collateral(More)
PURPOSE To retrospectively investigate the difference between conventionally fractionated (CF) and hyperfractionated (Hfx) radiation therapy (RT), with and without either daily cisplatin (CDDP) or carboplatin (CBDCA), in patients with locally advanced squamous cell carcinoma of the head and neck (SCCHN) enrolled onto two consecutive prospective randomized(More)
Several single nucleotide polymorphisms in survivin gene promoters, notably -31G/C, have been shown to modulate the expression and activity of the survivin protein. Consequently, the -31G/C polymorphism has been identified as a risk factor for the development of several types of tumors. The aim of this study was to investigate a possible association between(More)
PURPOSE To provide a 10-year update of hyperfractionated radiation therapy (Hfx RT) in adults with incompletely resected supratentorial low-grade glioma. METHODS AND MATERIALS A total of 37 patients were treated with 55 Gy in 50 fractions in 25 treatment days in 5 weeks to tumor plus 2 cm, and additional 17.6 Gy given in 16 fractions in 8 treatment days(More)
OBJECTIVE The aim of this study was to compare changes in temperature of the surrounding bone at various osteotomy depths during implant site preparation by bone condensing and by bone drilling as well as the dynamics of their change. STUDY DESIGN In the present "in vitro" study, pig ribs with uniform thickness of cortical bone of 2 mm were used. Lateral(More)
