545 Background: We have previously shown the prognostic value of PD-L1 protein and gene expression in early breast cancer (BC), however, the prognostic role of PD-1 expression remains unclear. Methods: The prognostic value of PD-1 in early BC was investigated using three different approaches: i) evaluation of PD-1 at the protein (IHC, immunohistoch...

Gene and protein expression of Programmed Death Ligand‐1 (PD‐L1) are prognostic in early breast cancer (BC), but their prognostic information is inconsistent at least in some biological subgroups. The validated prognostic gene signatures (GS) in BC are mainly based on proliferation and estrogen receptor (ER)‐related genes. Here we aimed to explore...
Conference Paper
Introduction: The SAM domain and HD domain 1 (SAMHD1) protein is a deoxynucleoside triphosphate (dNTP) triphosphohydrolase initially described to restrict human immunodeficiency virus type 1 (HIV-1) in the immune cells through depletion of intracellular dNTP substrates required for HIV-1 replication. Because of its ability to deplete the dNTP pool,...

Inactivating mutations in the SETD2 gene, encoding for a nonredundant histone H3 methyltransferase and regulator of transcription, is a frequent molecular feature in clear cell renal cell carcinomas (ccRCC). SETD2 deficiency is associated with recurrence of ccRCC and bears low prognostic values. Targeting autophagy, a conserved catabolic process wi...

Signal transducer and activator of transcription 3 (STAT3) is an oncogene and multifaceted transcription factor involved in multiple cellular functions. Its role in modifying anti-tumor immunity has been recently recognized. In this study, the biologic effects of STAT3 on immune checkpoint expression and anti-tumor responses were investigated in br...

The superior vena cava syndrome (SVCS) involves a group of symptoms deriving from obstruction or compression of the superior vena cava. Malignant causes represents the majority of all cases of SVCS. Iatrogenic causes may be responsible for SVCS, considering the presence of intravascular devices. Infectious causes such as syphilis and tuberculosis h...

Background Can learning outcomes be transformed in useful tools revealing strong and weak learning outcomes, learners, teachers; reporting student self-assessment overestimation; informing formative feedback and summative examinations? Methods Based on the ESMO / ASCO global curriculum, 66 level-two learning outcomes were identified and transforme...
Article
Purpose: Conflicting data have been reported on the prognostic value of PD-L1 protein and gene expression in breast cancer.Experimental Design: Medline, Embase, Cochrane Library, and Web of Science Core Collection were searched, and data were extracted independently by two researchers. Outcomes included pooled PD-L1 protein positivity in tumor cel...
Article
550 Background: We have previously demonstrated that PD-L1 mRNA expression can serve as prognostic biomarker in breast cancer (BC). In ER+/HER2- BC, RS and 70-gene signature are used to predict the risk of recurrence and benefit from chemotherapy. Methods: Discovery cohort (cohort 1) included 302 patients diagnosed with primary ER+/HER2- BC (1997-2...
Article
e14284 Background: Conflicting data have been reported on the prognostic value of PD-L1 expression per immunohistochemistry (IHC) in breast cancer (BC). There is a paucity of data on the role of PD-L1 gene expression (GE). Methods: Medline, Embase, Cochrane Library and Web of Science Core Collection were searched and data were extracted independent...

Cancer immunotherapy has altered the management of human malignancies, improving outcomes in an expanding list of diseases. Breast cancer - presumably due to its perceived low immunogenicity - is a late addition to this list. Furthermore, most of the focus has been on the triple negative subtype because of its higher tumor mutational load and lymph...

Introduction:PD-L1 expression as assessed by immunohistochemistry (IHC) is a clinically relevant biomarker in certain malignancies such as lung cancer, since it selects appropriate candidates for PD-1 blockade. Since these agents are under evaluation for breast cancer, discovering and validating predictive biomarkers is of outmost importance. Howev...

Although primary and secondary prevention strategies are widely applied, a significant number of women will develop recurrent or metastatic cervical cancer. In addition, 5% of newly diagnosed cervical cancers of the uterus are already metastatic. The established platinum-based chemotherapy remains the gold standard for advanced stages, but the prog...

Introduction: Renal cell carcinoma represents a neoplasm with usually aggressive behavior. Due to its nature, it is often diagnosed in an advanced stage or when metastatic dissemination has been occurred. The aim of this review is to provide an overview of the current management of metastatic renal cell carcinoma and briefly discuss the potential...

The programmed death protein 1 (PD-1) and its ligand (PD-L1) represent a well-characterized immune checkpoint in cancer, effectively targeted by monoclonal antibodies that are approved for routine clinical use. The regulation of PD-L1 expression is complex, varies between different tumor types and occurs at the genetic, transcriptional and post-tra...

Non-Hodgkin lymphomas commonly show extranodal involvement (25-30%) but primary diffuse large B-cell lymphomas(DLBCL) with extranodal localization represent clinically and molecularly distinct entities. The present study involved retrospective analysis of case records of 4 patients who were diagnosed with extranodal DLBCL between 2010 and 2016 at t...

Background: Transcriptomic profiles have shown promise as predictors of response to neoadjuvant chemotherapy in breast cancer (BC). This study aimed to explore their predictive value in the advanced BC (ABC) setting. Methods: In a Phase 3 trial of first-line chemotherapy in ABC, a fine needle aspiration biopsy (FNAB) was obtained at baseline. In...

Background Plasmablastic lymphoma (PBL) is a rare, aggressive B-cell lymphoma with poor prognosis usually found in the oral cavity of HIV-positive patients. Chronic lymphocytic leukemia (CLL) is an indolent B-cell lymphoma with a variable clinical course. Transformation of CLL to PBL as Richter's syndrome is rare while coexistence of CLL and PBL at...

Non-epithelial ovarian cancers (NEOC) are a group of fascinating but uncommon malignancies which can be extremely challenging to treat. Collectively, these tumours only represent 10-15% of all ovarian cancers and occur in all age groups from childhood to old age. This broad term includes diverse tumours of germ cell origin, sex cord-stromal cell or...

Recent data suggest that shifting from single biopsy-based testing to comprehensive intratumor diversity using next-generation sequencing (NGS) technologies could reduce tumor resistance to modern therapy. Could intratumor heterogeneity be used as a biomarker to predict primary tumor responsiveness and improve initial systemic treatment?
