(1) Background: The prompt diagnosis of anterior mediastinal lesions is a challenge due to their often being categorized as malignant tumours. Ultrasound-guided Transthoracic Core Needle Biopsy (US-TCNB) is an innovative technique that is arousing increasing interest in clinical practice. However, studies in this area are still scarce.

Article Synopsis
  • The study investigates how myeloid nuclear differentiation antigen (MNDA) expression can aid in differentiating lymphoplasmacytic lymphoma (LPL) from splenic marginal zone B-cell lymphoma (SMZL) since their characteristics often overlap.
  • It was found that while the MYD88 p.Leu265Pro mutation was identified in some LPL cases, MNDA was predominantly negative in these cases, indicating it could help rule out LPL.
  • MNDA expression was more frequent in SMZL cases, and additional specific immunohistochemical features correlated with MNDA positivity, suggesting its usefulness in diagnosing SMZL when genetic mutation tests are not available.

In recent years, the outcome of mantle cell lymphoma (MCL) has improved, especially in younger patients, receiving cytarabine-containing chemoimmunotherapy and autologous stem cell transplantation. Nevertheless, a proportion of MCL patients still experience early failure. To identify biomarkers anticipating failure of intensive chemotherapy in MCL, we performed target resequencing and DNA profiling of purified tumor samples collected from patients enrolled in the prospective (high-dose chemoimmunotherapy followed by autologous transplantation and randomized lenalidomide maintenance).

An accurate diagnosis of clinically distinct subgroups of aggressive mature B cell lymphomas is crucial for the choice of proper treatment. Presently, precise recognition of these disorders relies on the combination of morphological, immunophenotypical, and cytogenetic/molecular features. The diagnostic workup in such situations implies the application of costly and time-consuming analyses, which are not always required, since an intensified treatment option is reasonably reserved to fit patients.

Article Synopsis
  • Peripheral T-cell lymphoma not otherwise specified (PTCL-NOS) is a diverse and poorly understood group of cancers with complex genetic characteristics.
  • In a study involving whole exome and RNA sequencing of 21 cases, researchers identified mutations in 137 genes, including significant findings related to the FAT1 tumor suppressor gene.
  • The presence of FAT1 mutations was linked to worse overall survival rates in patients, underscoring their relevance for understanding and potentially managing PTCL-NOS.

Objectives: Flow cytometry (FC) has become a useful support for cytomorphologic evaluation (CM) of fine-needle aspirates (FNA) and serous cavity effusions (SCE) in cases of suspected non-Hodgkin lymphoma (NHL). FC results may be hampered by the scarce viability and low cellularity of the specimens.

Study Design: We developed a single-tube FC assay (STA) that included 10 antibodies cocktailed in 8-color labeling, a cell viability dye, and a logical gating strategy to detect NHL in hypocellular samples.

Anaplastic large-cell lymphoma (ALCL) is a clinical and biological heterogeneous disease that includes systemic anaplastic lymphoma kinase (ALK)-positive and ALK-negative entities. To discover biomarkers and/or genes involved in ALK-negative ALCL pathogenesis, we applied the cancer outlier profile analysis algorithm to a gene expression profiling data set including 249 cases of T-cell non-Hodgkin lymphoma and normal T cells. Ectopic coexpression of ERBB4 and COL29A1 genes was detected in 24% of ALK-negative ALCL patients.

A systematic characterization of the genetic alterations driving ALCLs has not been performed. By integrating massive sequencing strategies, we provide a comprehensive characterization of driver genetic alterations (somatic point mutations, copy number alterations, and gene fusions) in ALK(-) ALCLs. We identified activating mutations of JAK1 and/or STAT3 genes in ∼20% of 88 [corrected] ALK(-) ALCLs and demonstrated that 38% of systemic ALK(-) ALCLs displayed double lesions.

Although anaplastic large-cell lymphomas (ALCL) carrying anaplastic lymphoma kinase (ALK) have a relatively good prognosis, aggressive forms exist. We have identified a novel translocation, causing the fusion of the TRAF1 and ALK genes, in one patient who presented with a leukemic ALK+ ALCL (ALCL-11). To uncover the mechanisms leading to high-grade ALCL, we developed a human patient-derived tumorgraft (hPDT) line.

Objective: Thymic carcinoma (TC) is a rare and invasive mediastinal tumor, with poor prognosis. Most of the previous published papers are single-institution based, reporting small series of patient, sometimes including palliative resection. This study collected patients with TC treated in 5 high-volume Italian Thoracic Surgery Institutions.

Objective: Lymphoid proliferations of the salivary glands can be either reactive or malignant. Diagnosis based solely on fine needle aspiration (FNA) cytology may be troublesome in view of the difficulty in distinguishing low-grade B-cell and mucosa-associated lymphoid tissue (MALT) lymphomas from reactive lymphoid proliferations. We report our experience with FNA cytology combined with flow cytometry (FC) immunophenotyping for the diagnosis of lymphoproliferative processes affecting the salivary glands.

A retrospective analysis of 1,792 solid tissues suggestive of lymphoma, submitted over a 12-year period, was carried out and flow cytometry (FC) results were compared with histologic findings. The final histologic diagnosis of cases documented in this report is as follows: 1,270 non-Hodgkin's lymphomas (NHL); 17 composite lymphomas; four NHL plus carcinomas; five post-transplant lymphoproliferative disorders; 105 Hodgkin's lymphomas (HL); eight acute leukemias; 42 tissue cancers; and 341 non-neoplastic diseases. A strong correlation between morphology and FC data was observed among hematological malignancies (1,268/1,304, 97.

Purpose: Primary testicular lymphoma (PTL) has poor prognosis with failures in contralateral testis, CNS, and extranodal sites. To prevent these events, we designed an international phase II trial (International Extranodal Lymphoma Study Group 10 [IELSG-10]) that addressed feasibility and activity of conventional chemoimmunotherapy associated with CNS prophylaxis and contralateral testis irradiation. The trial was conducted by the IELSG and the Italian Lymphoma Foundation.

Neuroendocrine tumors of the thymus (NETTs) are unusual thymic neoplasms that were misdiagnosed as thymomas until the 1970s, when they eventually acquired a distinct identity. No collective large series have been published so far, and information about clinical presentation, diagnosis, histology, and treatment is derived from analysis of the case series and case reports published over a long period. NETTs are more aggressive than their pulmonary and abdominal counterparts, presenting at a more advanced stage, often with distant metastases, and are associated with poor long-term survival.
