CD20-Negative Large B-Cell Lymphomas: The Diagnostic Challenge of Tumors with Downregulation of Mature B-Cell Marker Expression.

CD20-negative aggressive B-cell lymphomas are a rare and heterogeneous group of lymphomas representing a diagnostic challenge for pathologists and a therapeutic issue for clinicians, because the outcome of these patients is poor with the current therapeutic approaches. CD20-negative aggressive lymphomas include plasmablastic lymphoma, primary effusion lymphoma, ALK-positive large B-cell lymphoma and HHV8-positive diffuse large B-cell lymphoma. Conditions of immunosuppression and viral infections, such as Epstein-Barr virus and Human Herpes virus 8, are associated with all of these lymphomas with the exclusion of ALK-positive large B-cell lymphoma, which occurs in immunocompetent hosts and is not associated with viral infections.

Purpose: Transverse colon cancer, which accounts for approximately 10% of all colon cancers, has a significant gap in the available scientific literature regarding the optimal minimally invasive surgical approach. This meta-analysis aims to compare the robotic and laparoscopic approaches for the surgical management of transverse colon cancer.

Methods: Our systematic review made use of Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines, in addition to Cochrane Handbook for Systematic Reviews of Interventions.

Diagnostic workout of glandular malignant lesions of the bladder according to the 5th WHO classification.

Glandular lesions involving the bladder are less common than conventional urothelial carcinoma, and they are often diagnostically challenging diseases, carrying different clinical outcomes. As a group, they encompass both primary and secondary neoplasms, with sometimes overlapping morphological features. In this scenario, proper clinical information is important, in that secondary involvement of the bladder may occur by direct extension or lymphatic/hematogenous spread from carcinomas at other sites, comprising prostate, colon, cervix, breast, and lung.

Primary Carcinomas of the Episiotomy Scar Site: A Systematic Literature Review.

Episiotomy is a perineal incision enlarging the vaginal opening during labor, preventing severe perineal/vaginal/ano-rectal lacerations. We performed a systematic literature review (PRISMA guidelines; Pubmed, Scopus and Web of Science databases) of primary malignant tumors arising from the episiotomy site. Thirteen primary carcinomas were reported, mainly endometriosis-related histotypes (77%) (nine clear cell, CCC; one endometrioid, EC) with only two vulvar invasive squamous cell carcinomas and one adenoid cystic carcinoma of Bartholin's gland.

Impact of Obesity on Short-Term Outcomes in Patients Undergoing Retroperitoneal Laparoscopic/Retroperitoneoscopic Adrenalectomy for Benign or Malignant Adrenal Diseases: A Meta-Analysis.

: Retroperitoneal laparoscopic adrenalectomy (RLA) is one of two laparoscopic procedures used to treat benign and malignant adrenal diseases. Obesity in patients undergoing minimally invasive adrenal surgery is a frequently discussed topic. Our meta-analysis aimed to provide updated evidence by comparing intraoperative and perioperative outcomes on non-obese (NOb) and obese (Ob) patients who underwent RLA due to benign or malignant disease.

The Novel Histological Prostatic Inflammation Score Helps Defining the Association Between Stromal and Glandular Inflammation with the Risk of Prostate Cancer at Prostate Biopsy.

There is emerging evidence of an inverse association between prostatic inflammation (PI) and prostate cancer (PCa) diagnosis and outcome. The Irani score, a validated system that scores PI according to the grade of stromal infiltration (Irani G) and the aggressiveness of glandular infiltration (Irani A), has indeed been found to be inversely associated with PCa diagnosis and outcome, but the presence of two categories (G and A) makes the performance of this score suboptimal. This study aimed to determine whether a novel prostatic inflammation score (PIS) that combines Irani G and A scores better defined the risk of being diagnosed with PCa at prostate biopsy (PBx).

Diagnostic and Therapeutic Aspects of Monoclonal Gammopathies of Renal Significance (MGRS): An Update.

Monoclonal gammopathy of renal significance (MGRS) refers to a group of renal disorders caused by a monoclonal immunoglobulin (MIg), secreted by a non-malignant B-cell clone. Unlike overt multiple myeloma or B-cell proliferation, MGRS does not meet those diagnostic criteria. However, it is associated with significant morbidity, due to severe renal, and sometimes systemic, lesions induced by the MIg.

Oncological outcomes and prognostic implications of T1 histo-anatomic substaging in the management of high-Grade non-muscle invasive bladder cancer: results from a large single centre series.

Purpose: This study aimed to comprehensively evaluate the prognostic value of T1 histo-anatomic substaging (T1a/T1b) for high grade (HG) non-muscle invasive bladder cancer (NMIBC) over a large single-centre cohort.

Materials And Methods: Patients with primary HG T1 NMIBC were identified from our Institutional database, between 2011 and 2022. Data from diagnosis to repeated transurethral resection of bladder tumour (RE-TURBT), bacillus Calmette-Guérin (BCG) treatment and follow-up were collected.

A Diagnostic Approach in Large B-Cell Lymphomas According to the Fifth World Health Organization and International Consensus Classifications and a Practical Algorithm in Routine Practice.

In this article, we provide a review of large B-cell lymphomas (LBCLs), comparing the recently published fifth edition of the WHO classification and the International Consensus Classification (ICC) on hematolymphoid tumors. We focus on updates in the classification of LBCL, an heterogeneous group of malignancies with varying clinical behaviors and different pathological and molecular features, providing a comparison between the two classifications. Besides the well-recognized diagnostic role of clinical, morphological and immunohistochemical data, both classifications recognize the ever-growing impact of molecular data in the diagnostic work-up of some entities.

Purpose: Prostatic urethral lift has been an effective ejaculation sparing treatment for benign prostatic hypertrophy. The aim of this study was to evaluate the effect on male semen parameters.

Methods: Between July 2014 and January 2022, 20 young men with urinary symptoms of BPH, unresponsive to drug treatment and motivated to preserve ejaculation for eventual paternity, underwent UroLift.

Programmed Death Ligand 1 (PD-L1) Expression in Lymphomas: State of the Art.

The interaction of programmed death-1 (PD-1) on T lymphocytes with its ligands Programmed Death Ligand 1 (PD-L1) and Programmed Death Ligand 2 (PD-L2) on tumor cells and/or tumor-associated macrophages results in inhibitory signals to the T-cell receptor pathway, consequently causing tumor immune escape. PD-L1/PD-L2 are currently used as predictive tissue biomarkers in clinical practice. Virtually PD-L1 levels expressed by tumor cells are associated with a good response to immune checkpoint blockade therapies targeting the PD-1/PD-L1 axis.

Integrating the PD-L1 Prognostic Biomarker in Non-Muscle Invasive Bladder Cancer in Clinical Practice-A Comprehensive Review on State-of-the-Art Advances and Critical Issues.

Bladder cancer (BC) is one of the most prevalent cancers worldwide. Non-muscle invasive bladder cancer (NMIBC), comprising the majority of initial BC presentations, requires accurate risk stratification for optimal management. This review explores the evolving role of programmed cell death ligand 1 (PD-L1) as a prognostic biomarker in NMIBC, with a particular focus on its implications in the context of Bacillus Calmette-Guérin (BCG) immunotherapy.

HELLS regulates transcription in T-cell lymphomas by reducing unscheduled R-loops and by facilitating RNAPII progression.

Chromatin modifiers are emerging as major determinants of many types of cancers, including Anaplastic Large Cell Lymphomas (ALCL), a family of highly heterogeneous T-cell lymphomas for which therapeutic options are still limited. HELLS is a multifunctional chromatin remodeling protein that affects genomic instability by participating in the DNA damage response. Although the transcriptional function of HELLS has been suggested, no clues on how HELLS controls transcription are currently available.

Prognostic Value of P63 Expression in Muscle-Invasive Bladder Cancer and Association with Molecular Subtypes-Preliminary Report.

There is an ongoing need for biomarkers that could reliably predict the outcome of BC and that could guide the management of this disease. In this setting, we aimed to explore the prognostic value of the transcription factor P63 in patients with muscle-invasive bladder cancer (MIBC) having undergone radical cystectomy. The correlation between P63 expression and clinicopathological features (tumor stage, nodes involvement, patterns of muscularis propria invasion, papillary architecture, anaplasia, concomitant carcinoma in situ, lymphovascular invasion, perineural invasion, necrosis) and molecular subtyping (basal and luminal type tumors) was tested in 65 radical cystectomy specimens and matched with cancer-specific survival (CSS) and overall survival (OS).

Initial management approach for localized/locally advanced disease is critical to guide metastatic castration-resistant prostate cancer care.

Background: Currently, several therapies are available for metastatic castration-resistant prostate cancer (mCRPC) but no specific clinical factors to personalize treatment. We first sought the prognostic value of duration on androgen-deprivation therapy (ADT) for hormone-sensitive prostate cancer (HSPC) in patients receiving androgen-receptor-signaling inhibitors (ARSI) for mCRPC.

Methods: A multicenter cohort of mCRPC patients who started ARSI between July 2011 and October 2021 was identified.

Co-occurrence of mutation and translocation in chronic myeloproliferative neoplasms: a potentially confounding genetic combination.

Myeloproliferative neoplasms (MPNs) are classified into Philadelphia (Ph) chromosome-positive chronic myeloid leukemia (CML) and Ph-negative MPNs. translocation is the key genetic event of CML, whereas mutations are molecular aberrations of Ph-negative MPNs. Despite initially considered mutually exclusive genetic aberrations, the co-occurrence of and has been reported in a limited number of cases.

Primary Anaplastic-Lymphoma-Kinase-Positive Large-Cell Lymphoma of the Central Nervous System: Comprehensive Review of the Literature.

Background: Primary anaplastic-lymphoma-kinase (ALK)-positive large-cell lymphoma of the central nervous system (PCNS ALK-positive ALCL) is a rare entity, with a limited consensus reached regarding its management. While this pathology often presents as solitary lesions, the occurrence of multiple tumors within the brain is not uncommon. The lack of distinctive radiological features poses a diagnostic challenge, leading to delays in initiating targeted therapy.
