INTRODUCTION: Multiparametric magnetic resonance imaging (mpMRI) has improved clinicians' ability to detect clinically significant prostate cancer (csPCa). Combining or fusing these images with the real-time imaging of transrectal ultrasound (TRUS) allows urologists to better sample lesions with a targeted biopsy (Tbx) leading to the detection of greater rates of csPCa and decreased rates of low-risk PCa. In this review, we evaluate the technical aspects of the mpMRI-guided Tbx procedure to identify possible sources of error and provide clinical context to a negative Tbx...

This case report describes in detail an erosive distal diaphyseal pseudotumor that occurred 6 years after a complex endoprosthetic hinge total knee arthroplasty (TKA). A female patient had conversion of a knee fusion to an endoprosthetic hinge TKA at the age of 62. At her scheduled 6-year follow-up, she presented with mild distal thigh pain and radiographs showing a 6-7 cm erosive lytic diaphyseal lesion that looked very suspicious for a neoplastic process. An en bloc resection of the distal femur and femoral endoprosthesis was performed...

BACKGROUND: Focal therapy for prostate cancer has been proposed as an alternative treatment to whole-gland therapies in selected men to diminish side effects in localized prostate cancer. As nowadays imaging cannot offer complete prostate cancer disease characterization, multicore systematic biopsies are recommended (transrectal or transperineal). Optical imaging techniques such as confocal laser endomicroscopy and optical coherence tomography allow in vivo, high-resolution imaging. Moreover, they can provide real-time visualization and analysis of tissue and have the potential to offer additive diagnostic information...

Purpose: The development of next-generation sequencing (NGS) has revolutionized the understanding of oncogenesis of multiple types of cancer, including non-small cell lung cancer (NSCLC). However, there has been some debate over the utility of NGS for predicting patient prognosis and determining molecular targeted therapy. Therefore, we sought to demonstrate the numerous applications of NGS in the prognostic predictions and treatment of NSCLC patients. Materials and methods: We performed NGS on either liquid or tissue tumor biopsies obtained from 53 NSCLC patients...

Multiparametric magnetic resonance imaging (mpMRI) of the prostate has allowed clinicians to better visualize and target suspicious lesions during biopsy. Targeted prostate biopsies give a more accurate representation of the true cancer volume and stage so that appropriate treatment or active surveillance can be selected. Advances in technology have led to the development of MRI and ultrasound fusion platforms used for targeted biopsies, monitoring cancer progression, and more recently for the application of focal therapy...

Soft tissue sarcomas are a heterogeneous group of rare malignancies. The diagnostic gold standard is conventional histomorphology with integrated immunohistochemistry. Molecular genetic profiling has identified new subgroups of undifferentiated sarcomas involving genetic rearrangements with creation of fusion genes. Accurate classification of sarcomas is critical for appropriate clinical decision-making which should involve a multidisciplinary team. A preoperative biopsy is necessary to confirm a diagnosis...

BACKGROUND: Non-small cell lung cancer (NSCLC) patients with epidermal growth factor receptor (EGFR) mutations or anaplastic lymphoma kinase (ALK) fusions show dramatic responses to specific tyrosine kinase inhibitors (TKIs); however, after 10-12 months, secondary mutations arise that confer resistance. We generated a murine xenograft model using patient-derived NSCLC cells isolated from the pleural fluid of two patients with NSCLC to investigate the mechanisms of resistance against the ALK- and EGFR-targeted TKIs crizotinib and osimertinib, respectively...

REVIEW
Jens Hillengass, Maximilian Merz, Stefan Delorme
The increasing percentage of patients achieving deep responses in multiple myeloma has led to the need for more sophisticated instruments to measure residual disease as a potential source of relapse. As minimal residual disease assessment is mostly performed on a bone marrow specimen from a certain area of the body, such samples have the limitation that they might not really represent the actual tumor burden, because focal accumulations of malignant cells might be either hit or missed. Magnetic resonance imaging is a highly sensitive technique for the assessment of tumor burden and can be performed as whole-body protocol, overcoming the problem of sampling error for minimal residual disease assessment...

AIMS: Rhabdomyosarcomas of bone are extremely rare, with fewer than 10 reported cases. A very rare subtype of spindle cell/sclerosing rhabdomyosarcoma harboring a FUS-TFCP2 fusion and involving both soft tissue and bone locations has very recently been reported. We report only the fourth case of this unusual, clinically aggressive rhabdomyosarcoma. MATERIAL AND RESULTS: A previously-well 72-year old male presented with a destructive lesion of the mandible. Morphological and immunohistochemical study of a needle biopsy and the subsequent resection showed a spindle cell rhabdomyosarcoma...

A 48-year-old man with a history of birdshot chorioretinitis presented with blurry vision, retro-bulbar pain and sinusitis. Though visual acuity was unaffected, he had left optic disc oedema and mild restriction of left eye abduction. His symptoms progressed quickly, with diplopia in primary gaze, epistaxis from his left nostril, and a left relative afferent pupillary defect (RAPD). On computed tomography, there was a mass in the nasal cavity that extended through the left cribriform plate and lamina papyracea and posteriorly into the optic canal...

INTRODUCTION AND OBJECTIVES: Patients with persistently elevated prostate specific antigen (PSA) and prior negative 12-core TRUS prostate biopsy (or biopsies) (systematic biopsy-SBx) are a diagnostic challenge. Repeat SBx or saturation biopsy in this cohort has been shown to have an even lower yield. The aim of our study is to compare the prostate cancer yield of magnetic resonance imaging (MRI) fusion biopsy (FBx) to SBx in a multi-institutional cohort comprised of patients with prior negative biopsies...

An 87-year old female presented with unsteady gait and occasional subcutaneous hematomas. Blood examination findings revealed pancytopenia and mild coagulopathy. Both the histopathological evaluation of bone marrow smears and bone marrow biopsy revealed a hypocellular bone marrow. However, APL cells were observed and PML-RARA fusion gene was detected. On the basis of these findings, the patient was diagnosed with hypoplastic acute promyelocytic leukemia. She received ATRA treatment and achieved complete remission (CR) 29 days from the commencement of therapy...

PURPOSE: For multiparametric MRI/Ultrasound fusion prostate biopsy (FUSBx) the number of taken biopsy cores is arbitrary established by urologists. Moreover, general consensus on the number of biopsy cores to be obtained from a single MRI-lesion is lacking. Therefore, we aimed to evaluate the feasibility of obtaining only one biopsy core per MRI-lesion. MATERIALS AND METHODS: We retrospectively evaluated 2128 biopsy cores of 1064 prostatic lesions (two cores per lesion) in 418 patients regarding prostate cancer (PCa) detection (histology) and Gleason score (GS) of the first biopsy core (FBC) compared to the second biopsy core (SBC)...

REVIEW
Maria Jesus Herrero, Yorick Gitton
FOXP2 encodes a transcription factor involved in speech and language acquisition. Growing evidence now suggests that dysregulated FOXP2 activity may also be instrumental in human oncogenesis, along the lines of other cardinal developmental transcription factors such as DLX5 and DLX6 [1-4]. Several FOXP familymembers are directly involved during cancer initiation, maintenance and progression in the adult [5-8]. This may comprise either a pro-oncogenic activity or a deficient tumor-suppressor role, depending upon cell types and associated signaling pathways...
