Targeted biopsy added to systematic biopsy improves cancer detection in prostate cancer screening.

Background: Magnetic resonance imaging (MRI)/ultrasound targeted biopsy has frequently been used together with a 12-core systematic biopsy for prostate cancer screening in the past few years. However, the efficacy of targeted biopsy compared to systematic biopsy, as well as its clinical-histologic correlation, has been assessed by a limited number of studies and is further investigated in this study.

Design: We collected 960 cases with both targeted and systematic prostate biopsies from 04/2019 to 04/2022 (Table 1).

Mixed squamous and clear cell ovarian adenocarcinoma arising from endometriosis in a 71 year old patient.

•This 71 year old patient was diagnosed with mixed squamous and clear cell ovarian adenocarcinoma.•Patient was surgically staged with guidance from frozen section.•Patient received adjuvant treatment with carboplatin and paclitaxel for 6 cycles.

Genomic and transcriptomic analysis of a library of small cell lung cancer patient-derived xenografts.

Access to clinically relevant small cell lung cancer (SCLC) tissue is limited because surgical resection is rare in metastatic SCLC. Patient-derived xenografts (PDX) and circulating tumor cell-derived xenografts (CDX) have emerged as valuable tools to characterize SCLC. Here, we present a resource of 46 extensively annotated PDX/CDX models derived from 33 patients with SCLC.

Multimodality imaging findings of visceral myopathy in a child presenting with palpable abdominal mass.

Bayramoğlu Z, Yılmaz R, Demir AA, Ataizi-Çelikel Ç, Kombak FE, İkinci A, Yekeler E. Multimodality imaging findings of visceral myopathy in a child presenting with palpable abdominal mass. Turk J Pediatr 2019; 61: 120-125.

BRAFV600E Immunohistochemistry in Papillary Thyroid Carcinomas: Relationship Between Clinical and Morphological Parameters.

Objective: To investigate the association of the BRAFV600E mutation with papillary thyroid carcinoma using clinical, morphological and prognostic parameters. We also intend to assess the utility of the BRAFV600E immunohistochemistry and compare it with BRAF polymerase chain reaction (RT-PCR).

Material And Method: We applied BRAFV600E immunohistochemistry in a cohort of 107 papillary carcinomas, 19 adenomas and 13 normal thyroid tissues that was chosen retrospectively between 2011 and 2015.

Clear Cell Sarcoma-Like Tumor of the Gastrointestinal Tract.

Clear cell sarcoma-like tumor of the gastrointestinal tract (CCSLGT) is a rare and relatively recently described entity. Here, we report a CCSLGT arising in the ileum of 28-year-old man. Histologically, the tumor composed of uniform, epithelioid or spindle cells that have eosinophilic cytoplasm and round, vesicular nucleus with single prominent nucleolus arranged in nests.

Concordance of immunohistochemistry between core needle biopsy and surgical resection of breast cancer.

Background/aim: The purpose of this study was to evaluate the concordance of immunohistochemical (IHC) parameters of breast lesions between the core needle biopsy (CNB) and the surgical resection specimen. Materials and methods: CNB and resection specimens of female patients were retrospectively analyzed. ER, PR, HER-2, and Ki-67 parameters were compared for each patient.

Allogeneic pluripotent stem cells suppress airway inflammation in murine model of acute asthma.

New strategies are needed to suppress airway inflammation and prevent or reverse airway remodeling in asthma. Reprogramming induced pluripotent stem cells (iPSCs) have the potential of embryonic stem cells (ESCs) and provide a resource for stem cell-based utility. The aim of this study was to evaluate the histopathological and immunomodulatory effects of ESCs and iPSCs for potential allogenic application in a murine model of acute asthma.

Suppressive effect of compact bone-derived mesenchymal stem cells on chronic airway remodeling in murine model of asthma.

New therapeutic strategies are needed in the treatment of asthma besides vaccines and pharmacotherapies. For the development of novel therapies, the use of mesenchymal stem cells (MSCs) is a promising approach in regenerative medicine. Delivery of compact bone (CB) derived MSCs to the injured lungs is an alternative treatment strategy for chronic asthma.
