Therapeutische Strategien bei malignen Weichteiltumoren
2001
Einleitung: Ziel einer Weichteiltumor-Registerstudie der Chirurgischen Arbeitsgemeinschaft Onkologie (CAO) der Deutschen Gesellschaft fur Chirurgie war die Erfassung der Behandlungsstrategien bei malignen Weichteiltumoren des Erwachsenen. Methodik: In 19 Monaten wurden Daten von 292 Patienten von 99 chirurgischen Kliniken Deutschlands nach einem speziell entwickelten Dokumentationsbogen prospektiv zur pratherapeutischen Biopsie, Vorbehandlung, definitiven chirurgischen Therapie, zu multimodalen Masnahmen und zum pathohistologischen Befund erhoben. Ergebnisse: 39 % der Tumoren wurden in Universitatskliniken, 36 % in Schwerpunktkrankenhausern und 24 % in Krankenhausern der Grundversorgung beh…
Antiblastic drug combinations with ifosfamide: an update
2003
Ifosfamide is an alkylating agent that is widely used in the treatment of various neoplasms, such as sarcomas, lymphomas, pediatric malignancies, germ cell tumors, lung, breast and ovarian cancer. The clinical toxicity of ifosfamide depends on the dose and administration schedules. The pharmacologic features of this drug enable its combination with other antiblastic agents, such as vinorelbine, gemcitabine, paclitaxel and docetaxel. Moreover, the pharmacologic profile of ifosfamide allows the use of this antiblastic drug in patients who have previously failed many other treatments, and a large percentage of responses has already been obtained. There is some concern about the optimal schedul…
A novel approach to fully characterize fiber network morphology of planar fibrous tissues and scaffolds
2010
Understanding how scaffold structure influences cell morphology, metabolism, phenotypic expression, and predicting mechanical behaviors have increasingly become crucial goals in the development of engineered tissue scaffolds. A novel image-based analysis algorithm that provides an automatic tool to characterize engineered tissue fiber network topology is presented. Micro architectural descriptors that unambiguously define the fiber network topology were detected, which include fiber orientation distribution, connectivity, intersection spatial density, and diameter. Algorithm performance was tested using actual sample scanning electron microscopy (SEM) images of (1) electrospun poly(ester ur…
Short, full-dose adjuvant chemotherapy (CT) in high-risk adult soft tissue sarcomas (STS): long-term follow-up of a randomized clinical trial from th…
2016
[Background] To report on long-term results of a phase 3 trial comparing three versus five cycles of adjuvant chemotherapy (CT) with full-dose epirubicin+ifosfamide in high-risk soft tissue sarcomas (STS).
Bone metastases in soft tissue sarcoma: a survey of natural history, prognostic value and treatment options
2013
Abstract Background We surveyed the natural history of bone metastases in patients affected by soft tissue sarcoma (STS). Methods This multicenter retrospective observational study included 135 patients. Histological subtype, characteristics of bone metastases, treatment, skeletal related events (SREs) and disease outcome were recorded. Results The most represented histological subtypes were leiomyosarcoma (27%) angiosarcoma (13%) and undifferentiated sarcoma (8%). Axial skeleton was the most common site for bone involvement (70%). In 27% of cases, bone metastases were present at the time of diagnosis. Fifty-four (40%) patients developed SREs and the median time to first SRE was 4 months (r…
Dioxin emissions and soft-tissue sarcoma: results of a population-based case-control study.
2004
International audience; BACKGROUND: In 1998, the French Ministry of Environment revealed that of 71 French municipal solid waste incinerators processing more than 6 metric tons of material per hour, dioxin emission from 15 of them was above the 10 ng international toxic equivalency factor/m3 (including Besançon, emitting 16.3 ng international toxic equivalency factor/m3) which is substantially higher than the 0.1 international toxic equivalency factor/m3 prescribed by a European directive of 1994. In 2000, a macrospatial epidemiological study undertaken in the administrative district of Doubs, identified two significant clusters of soft-tissue sarcoma and non Hodgkin lymphoma in the vicinit…
Postoperative Radiation Therapy in Patients with Extracranial Chondrosarcoma: A Joint Study of the French Sarcoma Group and Rare Cancer Network
2020
International audience; PurposePostoperative radiation therapy (poRT) of intracranial/skull base chondrosarcomas (CHSs) is standard treatment. However, consensus is lacking for poRT in extracranial CHS (eCHS) owing to their easier resectability and intrinsic radioresistance. We assessed the practice and efficacy of poRT in eCHS.Methods and MaterialsThis multicentric retrospective study of the French Sarcoma Group/Rare Cancer Network included patients with eCHS who were operated on between 1985 and 2015. Inverse propensity score weighting (IPTW) was used to minimize poRT allocation biases.ResultsOf 182 patients, 60.4% had bone and 39.6% had soft-tissue eCHS. eCHS were of conventional (31.9%)…
Childhood soft tissue sarcomas incidence and survival in European children (1978-1997): Report from the Automated Childhood Cancer Information System…
2006
This population-based study is based on 5802 cases of soft tissue sarcomas (STS) in children aged 0-14 years extracted from the database of the Automated Childhood Cancer Information System (ACCIS) and registered in population-based cancer registries in Europe for the period 1978-1997. STS represent almost 8% of neoplasms in children, almost half of whom are less than 5 years at diagnosis. Rhabdomyosarcoma is the most frequent childhood STS (50%). During 1988-1997 the age-standardised incidence of STS in Europe was 9.1 per million children, lowest in the West and East and highest in the North. The incidence of STS increased almost 2% per year over the period 1978-1997, attributable mostly t…
Low energy KTP laser in oral soft tissue surgery: A 52 patients clinical study
2011
Objectives: Since 1962 laser appliances have been used for soft tissues surgery of oral cavity with significant advantages compared to the traditional instruments: excellent bleeding control, possibility to avoid the use of suture, good patient compliance thanks to a decrease of intra- and post-operative discomfort and biostimulating effect. Unfortunately, the wavelengths so far used have been seen to cause, in association with an excellent ablation capacity, heat damage of the tissues that can decrease healing process and cause a greater discomfort to patients. The aim of this study was to evaluate the laser-assisted KTP laser surgery at low power in terms of characteristics of interventio…
Fibrosarcoma in pediatric patients: Results of the Italian Cooperative Group Studies (1979-1995)
2001
Background and Objectives Fibrosarcoma is a rare soft tissue sarcoma (STS) that has two peaks of incidence in pediatric patients: one in infants and young childern (infantile fibrosarcoma), another in older children (“adult type” fibrosarcoma). The purpose of this study was to describe the clinical features and the treatment results in patients affected by fibrosarcoma enrolled in two consecutive studies run by the STS-Italian Cooperative Group (ICG) between 1979 and 1995. Patients and Methods Twenty-five evaluable patients were grouped according the intergroup rhabdomyosarcoma staging (IRS) system: 12 Gr I, 5 Gr II, 8 Gr III. The cut-off point between the two forms was considered the age o…
