BACKGROUND Current recommendations on the treatment of neuroendocrine carcinoma of the larynx (NCL) are based on anecdotal evidence. With this meta-analysis, our purpose was to provide clinicians with more substantiated guidelines in order to improve the treatment outcome of the patients affected with NCL. METHODS A structured literature search for all(More)
BACKGROUND Nasal defects resulting from tumor resection are preferably rehabilitated with implant-retained nasal prostheses. Aftercare, clinical outcome of the implants, and patients' satisfaction with implant-retained nasal prostheses were assessed. METHODS Twenty-eight consecutive patients needing total rhinectomy because of tumor resection between 1998(More)
OBJECTIVES/HYPOTHESIS Recurrent respiratory papillomatosis (RRP) is a rare, benign, wart-like disease for which no curative treatment exists. The goal of treatment is total surgical removal of the epithelial lesions to keep the airway open and the voice sufficient. Therefore, it is essential to visualize all papillomatous lesions. The present study aims to(More)
PURPOSE Several studies have reported clinical behavior and chemotherapy resistance in leiomyosarcomas, but these studies did not differentiate between soft tissue leiomyosarcomas (LMS) and malignant gastrointestinal stromal tumors (GIST). Multidrug resistance (MDR) has been associated with the expression of P-glycoprotein (P-gp), multidrug resistance(More)
UNLABELLED This study was undertaken to investigate the relationship of PET using fluorodeoxyglucose (FDG) or L-[1-11C]-tyrosine (TYR) with histopathologic findings in soft-tissue tumors, before and after therapy. Histopathologic parameters that were studied were tumor grade, mitotic rate, proliferation activity and amount of necrosis. METHODS PET with(More)
The radiolabeled amino acid L-3-[123I]-iodo-alpha-methyltyrosine (IMT) is a new tumor tracer that accumulates in many tumors and is suitable for single photon emission computed tomography (SPECT) imaging. Using IMT SPECT, we studied 32 patients with a soft-tissue tumor suspected to be a soft-tissue sarcoma to determine whether: (a) tumors can be visualized;(More)
PURPOSE Leiomyosarcomas (LMS) of deep and superficial tissues were examined to identify prognostic markers explaining their different biological behaviour and to define differences between cutaneous and subcutaneous LMS. LMS and leiomyomas (LM) of the skin were compared to and consistent differences that could aid in the (sometimes difficult) diagnosis. (More)
Protein synthesis rate (PSR) can be assessed in vivo using positron emission tomography with L-[1-11C]tyrosine (TYR-PET). Biological activity of soft tissue sarcomas (STS) can be measured in vitro by the mitotic rate and number of proliferating cells. In STS the grade of malignancy, in which the mitotic index plays a major role, is considered to be the(More)
Treatment choice in elderly pharyngeal cancer patient is disputed. This study was aimed to asses association of co-morbidity, complications and survival in different treatment modalities of pharyngeal cancer patients. Retrospective analysis of pharyngeal cancer patients, diagnosed between 1997 and 2007 in a tertiary referral hospital was performed. Patients(More)
Recent studies suggest that increased activity of the coagulation system, measured with sensitive assays for activation markers, may be important in the pathogenesis of vascular occlusion in sickle cell disease (SCD). Since most of these studies were carried out in adult patients and SCD is an inherited disorder with severe morbidity even in childhood, we(More)
