Phenotype and genotype features of Vietnamese children with pachyonychia congenita.

Background: Pachyonychia congenita (PC) is a group of autosomal dominant disorders caused by mutations in one of five keratin genes (KRT6A, KRT6B, KRT6C, KRT16, or KRT17). PC is an extremely rare condition. To our knowledge, this is the largest genotype-phenotype study of PC in a Vietnamese population to date.

Long-term outcome of molecular subgroups of GIST patients treated with standard-dose imatinib in the BFR14 trial of the French Sarcoma Group.

Background: The added value of tumoural genomic profiles to conventional clinico-biological factors to predict progression-free survival (PFS) and overall survival (OS) was prospectively investigated in patients with advanced gastrointestinal stromal tumours (GIST) treated in the BFR14 study.

Methods: Of the 434 included patients, mutational analysis was performed in 322 patients. Survival analysis was performed in patients with validated mutational status.

Trabectedin in patients with advanced soft tissue sarcoma: a retrospective national analysis of the French Sarcoma Group.

Aim: The French Sarcoma Group performed this retrospective analysis of the 'RetrospectYon' database with data of patients with recurrent advanced soft tissue sarcoma (STS) treated with trabectedin 1.5 mg/m(2) as a 24-h infusion every three weeks.

Methods: Patients who achieved non-progressive disease after six initial cycles could receive long-term trabectedin treatment until disease progression.

Randomised phase III trial of trabectedin versus doxorubicin-based chemotherapy as first-line therapy in translocation-related sarcomas.

Aim: This randomised phase III trial evaluated first-line trabectedin versus doxorubicin-based chemotherapy (DXCT) in patients with advanced/metastatic translocation-related sarcomas (TRS).

Methods: Patients were randomly assigned (1:1) to receive trabectedin 1.5mg/m2 24-h intravenous (i.

Results of an international randomized phase III trial of the mammalian target of rapamycin inhibitor ridaforolimus versus placebo to control metastatic sarcomas in patients after benefit from prior chemotherapy.

Purpose: Aberrant mammalian target of rapamycin (mTOR) signaling is common in sarcomas and other malignancies. Drug resistance and toxicities often limit benefits of systemic chemotherapy used to treat metastatic sarcomas. This large randomized placebo-controlled phase III trial evaluated the mTOR inhibitor ridaforolimus to assess maintenance of disease control in advanced sarcomas.

Efficacy and safety of regorafenib for advanced gastrointestinal stromal tumours after failure of imatinib and sunitinib (GRID): an international, multicentre, randomised, placebo-controlled, phase 3 trial.

Background: Until now, only imatinib and sunitinib have proven clinical benefit in patients with gastrointestinal stromal tumours (GIST), but almost all metastatic GIST eventually develop resistance to these agents, resulting in fatal disease progression. We aimed to assess efficacy and safety of regorafenib in patients with metastatic or unresectable GIST progressing after failure of at least imatinib and sunitinib.

Methods: We did this phase 3 trial at 57 hospitals in 17 countries.

Pazopanib for metastatic soft-tissue sarcoma (PALETTE): a randomised, double-blind, placebo-controlled phase 3 trial.

Background: Pazopanib, a multitargeted tyrosine kinase inhibitor, has single-agent activity in patients with advanced non-adipocytic soft-tissue sarcoma. We investigated the effect of pazopanib on progression-free survival in patients with metastatic non-adipocytic soft-tissue sarcoma after failure of standard chemotherapy.

Methods: This phase 3 study was done in 72 institutions, across 13 countries.

Phase III trial of standard versus dose-intensified doxorubicin, ifosfamide and dacarbazine (MAID) in the first-line treatment of metastatic and locally advanced soft tissue sarcoma.

Multidrug chemotherapy increases responses in advanced soft tissues sarcoma. Can a 20% increase of relative dose intensity of the MAID regimen, more improve responses? From 1994 to 1997, 162 patients were randomized in a phase III study to the conventional drug combination (6 cycles of MAID: 60, 7,500, 900 mg/m(2) for doxorubicin, ifosfamide and dacarbazine respectively), or at doses 20-33% higher per cycle (5 cycles of intensified MAID for similar cumulative doses) with systematic G-CSF. Primary endpoint was response rate; secondary were toxicity, event-free and overall survival.

Randomized trial comparing bleomycin/etoposide/cisplatin with alternating cisplatin/cyclophosphamide/doxorubicin and vinblastine/bleomycin regimens of chemotherapy for patients with intermediate- and poor-risk metastatic nonseminomatous germ cell tumors: Genito-Urinary Group of the French Federation of Cancer Centers Trial T93MP.

Purpose: Two chemotherapy regimens for intermediate- and poor-risk metastatic nonseminomatous germ cell tumors were compared for efficacy and toxicity.

Patients And Methods: From February 1994 to February 2000, 190 patients were randomly assigned between either four cycles of BEP (bleomycin 30 mg d1, d8, d15; etoposide 100 mg/m(2) d1-5; cisplatin 20 mg/m(2) d1-5) or four to six alternating cycles of CISCA/VB (cyclophosphamide 400 mg/m(2) d1-2, doxorubicin 35 mg/m(2) d1-2, cisplatin 100 mg/m(2) d3/vinblastine 2.5 mg/m(2) d1-5, bleomycin 25 mg/m(2) d1-5).

Dedifferentiated liposarcomas with divergent myosarcomatous differentiation developed in the internal trunk: a study of 27 cases and comparison to conventional dedifferentiated liposarcomas and leiomyosarcomas.

Dedifferentiated liposarcoma (DLPS) is one of the most frequent sarcomas of the retroperitoneum and represents most undifferentiated sarcomas of the internal trunk. In about 5% cases, the dedifferentiated component is an heterologous sarcoma such as leiomyosarcoma or rhabdomyosarcoma. We reviewed a series of 65 sarcomas with a myogenic differentiation developed in the internal trunk for which initial diagnoses were leiomyosarcoma (37), rhabdomyosarcoma (6), malignant mesenchymoma (6), and DLPS (16).
