We report 12 European cases of pyothorax-associated lymphomas occurring 30-67 years following artificial pneumothorax for pleuropulmonar tuberculosis. Eleven patients presented with a localized pleural tumor mass, whereas one patient also had liver involvement. Histologic examination showed a diffuse proliferation of large lymphoid cells with frequent(More)
The SDF-1/CXCR4 pathway has been suggested to play a role in the metastatic dissemination of various tumours. We assessed the prognostic impact of SDF-1 and CXCR4 expression in head and neck squamous cell carcinoma (HNSCC). Seventy-one HNSCC samples collected at the time of initial diagnosis were retrospectively analysed. SDF-1 and CXCR4 expression levels(More)
Reliable information regarding the current prevalence of peripheral T-cell lymphoma (PTCL) entities is missing. Herein we report on the frequency of PTCL entities in France between 2010 and 2013. Using Lymphopath, a national lymphoma network established by the French National Cancer Agency, which covers about 70 % of all lymphomas currently diagnosed in(More)
[(18)F]-fluorodeoxyglucose positron emission tomography (FDG-PET) imaging is essential to optimize the initial staging and to predict the prognosis of diffuse large B-cell lymphoma (DLBCL). To assess the relationship between the germinal center B cell-like/activated B cell-like (GCB/ABC) classification and PET scan features in DLBCL, 57 cases treated with(More)
PURPOSE Various segmentation methods for 18F-fluoro-2-deoxy-d-glucose (FDG) positron emission tomography/computed tomography (PET/CT) images were correlated with pathological volume in breast cancer patients as a model of small mobile tumours. METHODS Thirty women with T2-T3/M0 breast invasive ductal carcinoma (IDC) were included prospectively. A(More)
Genomic alterations play a crucial role in the development and progression of diffuse large B-cell lymphomas (DLBCLs). We determined gene copy number alterations (GCNAs) of TP53, CDKN2A, CDKN1B, BCL2, MYC, REL, and RB1 with a single polymerase chain reaction (PCR) assay (quantitative multiplex PCR of short fragments [QMPSF]) in a cohort of 114 patients with(More)
Oral squamous cell carcinomas (OSCCs) are described as the result of a multistep tumorigenesis process. In order to develop useful diagnosis of pre-malignant lesions, expression of p53 family members and the cancer stem cell (CSCs) marker, CD44v6, were studied in histologically normal oral epithelium, precancerous lesions and succeeding invasive OSCCs. p53(More)
Acquired estrogen receptor gene (ESR1) mutations have been recently reported as a marker of resistance to aromatase inhibitors in hormone receptor positive metastatic breast cancer. We retrospectively considered seven patients treated for metastatic breast cancer with available samples from the primary tumor before any treatment, cryopreserved metastasis(More)
To further unravel the molecular pathogenesis of diffuse large B-cell lymphoma (DLBCL), we performed high-resolution comparative genomic hybridization on lymph node biopsies from 70 patients. With this strategy, we identified microdeletions of genes involved in the mutation mismatch repair (MMR) pathway in two samples. The first patient presented with a(More)
