Inflammatory and Nested Testicular Sex Cord Tumor: A Novel Neoplasm With Aggressive Clinical Behavior and Frequent EWSR1::ATF1 Gene Fusions.

A subset of malignant testicular sex cord tumors (TSCTs), heretofore interpreted as Sertoli cell tumors, not otherwise specified, exhibits distinctive morphologic features that partially overlap with those of seminoma. In this study, we evaluated the clinicopathologic and molecular characteristics of 13 such tumors. The patients were 20 to 73 years old (median, 36 y), and all with available data presented with testicular masses (median size, 3 cm), with 2 having synchronous retroperitoneal metastases.

Gender-Specific Molecular and Clinical Features Underlie Malignant Pleural Mesothelioma.

Malignant pleural mesothelioma (MPM) is an aggressive cancer that occurs more frequently in men, but is associated with longer survival in women. Insight into the survival advantage of female patients may advance the molecular understanding of MPM and identify therapeutic interventions that will improve the prognosis for all MPM patients. In this study, we performed whole-genome sequencing of tumor specimens from 10 MPM patients and matched control samples to identify potential driver mutations underlying MPM.

Classifying cytogenetics in patients with acute myelogenous leukemia in complete remission undergoing allogeneic transplantation: a Center for International Blood and Marrow Transplant Research study.

Cytogenetics play a major role in determining the prognosis of patients with acute myelogenous leukemia (AML). However, existing cytogenetics classifications were developed in chemotherapy-treated patients and might not be optimal for patients undergoing allogeneic hematopoietic cell transplantation (HCT). We studied 821 adult patients reported to the Center for International Blood and Marrow Transplant Research (CIBMTR) who underwent HCT for AML in first or second complete remission between 1999 and 2004.

Stimulation of chronic lymphocytic leukemia cells with CpG oligodeoxynucleotide gives consistent karyotypic results among laboratories: a CLL Research Consortium (CRC) Study.

Cytogenetic abnormalities are important prognostic indicators in CLL. Historically, only interphase cytogenetics was clinically useful in CLL, because traditional mitogens are not effective mitotic stimulants. Recently, CpG-oligodeoxynucleotide (ODN) stimulation has shown effectiveness in CLL cells.
