BACKGROUND The morphological evaluation of tumor-infiltrating lymphocytes (TILs) in breast cancer (BC) is gaining momentum as evidence strengthens for the clinical relevance of this immunological biomarker. Accumulating evidence suggests that the extent of lymphocytic infiltration in tumor tissue can be assessed as a major parameter by evaluation of(More)
BACKGROUND We have previously shown the prognostic importance of tumor-infiltrating lymphocytes (TILs) in newly diagnosed triple-negative breast cancer (TNBC) using tumor samples from a large clinical trial cohort. In this study, we aimed to validate these findings and also investigate associations with trastuzumab benefit in HER2-overexpressing disease(More)
PURPOSE Previous preclinical and clinical data suggest that the immune system influences prognosis and response to chemotherapy (CT); however, clinical relevance has yet to be established in breast cancer (BC). We hypothesized that increased lymphocytic infiltration would be associated with good prognosis and benefit from immunogenic CT-in this case,(More)
Objectives. To compare prostate cancer detection rates of extended 2D versus 3D biopsies and to further assess the clinical impact of this method in day-to-day practice. Methods. We analyzed the data of a cohort of 220 consecutive patients with no prior history of prostate cancer who underwent an initial prostate biopsy in daily practice due to an abnormal(More)
The aim of this study was to determine the prevalence of human papillomavirus (HPV) in patients with laryngeal benign lesions (LBLs) and laryngeal squamous cell carcinomas (LSCCs) using a sensitive E6/E7 type-specific PCR. Paraffin-embedded samples from LBL (n=39) and LSCC patients (n=67) were evaluated for the presence of HPV DNA by GP5+/GP6+ consensus PCR(More)
OBJECTIVES/HYPOTHESIS The prevalence of human papillomavirus (HPV) in a clinical series of 162 patients with oral squamous cell carcinoma (OSCC) was studied. Furthermore, we analyzed the correlation between the immunohistochemical expression of p16, p53, epidermal growth factor receptor (EGFR), and HPV status to predict survival in OSCC patients.

AIMS This study tests the hypothesis that histopathological fingerprinting of galectins, which are emerging multifunctional effectors in cell sociology, could refine the differential diagnosis of salivary tumours. METHODS AND RESULTS We applied non-crossreactive polyclonal antibodies against galectin-1 (Gal-1), galectin-3 (Gal-3), galectin-7 (Gal-7) and(More)
Warthin's tumor of the parotid gland is assumed to originate from the proliferation of epithelial inclusions within parotid lymph nodes. In that case, these cells are supposed to retain characteristics similar to common salivary gland ductal cells. Using immunohistochemical fingerprinting with four members of the family of adhesion/growth-regulatory(More)
We investigated the prevalence of human papillomavirus (HPV) in a clinical series of 72 patients with head and neck squamous cell carcinoma (HNSCC) using a retrospective and prospective study design. The majority of patients were smokers and/or drinkers and were treated with concomitant chemoradiotherapy (CCR). Furthermore, we assessed the impact of HPV(More)
A lethal intoxication case, which occurred in Brussels, Belgium, is described. A 20-year-old man died following the ingestion of pasta contaminated with Bacillus cereus. Emetic strains of B. cereus were isolated, and high levels of cereulide (14.8 μg/g) were found in the spaghetti meal.
