BackgroundFor many years, first-line treatment for locally advanced or metastatic soft-tissue sarcoma has been doxorubicin. This study compared gemcitabine and docetaxel versus doxorubicin as sarcoma.MethodsThe GeDDiS trial was a randomised controlled phase 3 done in 24 UK hospitals one Swiss Group Clinical Cancer Research (SAKK) hospital. Eligible patients had histologically confirmed of Trojani grade 2 3, disease progression before enrolment, no previous chemotherapy any cancer. Patients...

These guidelines were drawn up following a consensus meeting of UK sarcoma specialists convened under the auspices British Sarcoma Group and are intended to provide framework for multidisciplinary care patients with soft tissue sarcomas. The published by European Society Medical Oncology (ESMO) National Comprehensive Cancer Network (NCCN) used as basis discussion adapted according clinical practice local requirements. Note was also taken Institute Health Clinical Excellence (NICE) improving...

Abstract BACKGROUND: Pigmented villonodular synovitis (PVNS) (also known as diffuse‐type giant cell tumor) and tenosynovial tumors (TGCT) are rare, usually benign neoplasms that affect the synovium tendon sheaths in young adults. These driven by overexpression of colony stimulating factor‐1 (CSF1). CSF1 is expressed a minority tumor cells, which, turn attract non‐neoplastic inflammatory cells express receptor (CSF1R) through paracrine effect. METHODS: Imatinib mesylate (IM) blocks CSF1R,...

The efficacy of palliative chemotherapy was investigated in a large group patients with advanced soft-tissue sarcomas (STS) treated on routine protocols.Patients STS who had first-line for and/or metastatic disease between 1991 and 2005 were identified from the Royal Marsden Hospital's sarcoma database. Patients Ewing sarcoma, rhabdomyosarcoma, desmoplastic small round cell tumor, gastrointestinal stromal tumors excluded study.In all, 488 (242 male, 246 female) fulfilled study criteria....

BACKGROUND The objectives of this study were to provide sunitinib patients with gastrointestinal stromal tumor (GIST) who otherwise unable obtain it and collect broad safety efficacy data from a large population advanced GIST after imatinib failure. (ClinicalTrials.gov identifier NCT00094029). METHODS Imatinibresistant/ intolerant received on an initial dosing schedule 50 mg daily in 6‐week cycles (4 weeks treatment, 2 off treatment). Tumor assessment frequency was according local practice,...

Soft tissue sarcomas (STS) are rare tumours arising in mesenchymal tissues. Gastrointestinal stromal tumour (GIST) is the commonest STS and arises within wall of gastrointestinal (GI) tract. While most GISTs occur stomach they do all parts GI As with other STS, it important that managed by expert teams, to ensure consistent optimal treatment, as well recruitment clinical trials, ongoing accumulation further knowledge disease. The development appropriate guidance, an experienced panel...

Alveolar soft-part sarcoma (ASPS) is a rare soft-tissue that unresponsive to chemotherapy. Cediranib, tyrosine-kinase inhibitor, has shown substantial activity in ASPS non-randomised studies. The Cediranib Soft Part Sarcoma (CASPS) study was designed discriminate the effect of cediranib from intrinsically indolent nature ASPS.In this double-blind, placebo-controlled, randomised, phase 2 trial, we recruited participants 12 hospitals UK (n=7), Spain (n=3), and Australia (n=2). Patients were...

Cancer genetics has to date focused on epithelial malignancies, identifying multiple histotype-specific pathways underlying cancer susceptibility. Sarcomas are rare malignancies predominantly derived from embryonic mesoderm. To identify specific mesenchymal cancers, we performed whole-genome germline sequencing 1644 sporadic cases and 3205 matched healthy elderly controls. Using an extreme phenotype design, a combined rare-variant burden ontologic analysis identified two sarcoma-specific...

There are neither prospective data nor agreement on the optimal routine follow-up procedures in patients treated for soft tissue sarcoma of limb. Data 174 consecutive with a limb undergoing by oncologists at single centre from 2003 to 2009 were included this analysis. The rate and site recurrence mode detection analysed. Outcome was assessed. Eighty-two (47%) experienced relapse any type. Isolated local occurred 26 synchronous pulmonary metastases five patients. Local recurrences detected...

Abstract Tenosynovial giant cell tumors (TGCT), are rare colony stimulating factor-1(CSF-1)-driven proliferative disorders affecting joints. Diffuse-type TGCT often causes significant morbidity due to local recurrences necessitating multiple surgeries. Imatinib mesylate (IM) blocks the CSF-1 receptor. This study investigated long term effects of IM in TGCT. We conducted an international multi-institutional retrospective assess activity IM: data was collected anonymously from individual...

GemDoc has activity in STS and used relapsed after failure at least one line chemotherapy. Our aim was to compare with Dox as STS. Methods: Patients (pts) from 24 UK sites 1 Swiss site were randomised receive 6 cycles 75 mg/m2 intravenously (IV) day every 3 weeks, or Gem 675 IV days 8 Doc weeks (wks).
