REVIEW
Andrea Kühnl, David Cunningham, Ian Chau
After decades of intense research on genetic alterations in cancer and successful implementation of genetically-based targeted therapies, the field of cancer epigenetics is only beginning to be fully recognized. The discovery of frequent mutations in genes modifying the epigenome in diffuse large B-cell lymphoma (DLBCL) has highlighted the outstanding role of epigenetic deregulation in this disease. Identification of epigenetically-driven DLBCL subgroups and development of novel epigenetic drugs have rapidly advanced...

A 69-year-old man, previously treated with pyridostigmine for myasthenia gravis (manifesting as ptosis and diplopia) was evaluated for several concomitant bilateral anterior orbital masses. Imaging revealed 3 discrete, solid masses within and around the orbits. An incisional biopsy demonstrated atypical lymphocytes positive for CD20 and Cyclin-D1, consistent with mantle cell lymphoma. The patient received induction chemotherapy with a rituximab-based regimen. He experienced resolution of his diplopia and ptosis after one cycle of chemotherapy and achieved complete remission of the orbital masses and myasthenia symptoms after 6 cycles...

REVIEW
Michael D Jain, John Kuruvilla
Classical Hodgkin lymphoma (cHL) is defined by malignant Reed-Sternberg (RS) cells that recruit non-malignant immune cells into a supportive tumour microenvironment. In cHL, this is driven, in part, by genomic alterations of the 9p24.1 locus encoding the immune checkpoint ligands PD-L1 and PD-L2. Therapeutic anti-PD-1 antibodies have been developed that competitively inhibit the interaction between PD-1 and its ligands. Clinical trials of anti-PD-1 antibodies in cHL demonstrate high overall response rates but relapses still occur and new clinical challenges exist for toxicity management and response assessment...

Intravenous inotuzumab ozogamicin (Besponsa(®); Pfizer) is an anti-CD22 monoclonal antibody-calicheamicin conjugate that binds to CD22-expressing tumour cells. Upon binding, the complex is internalised and the cytotoxic calicheamicin derivative is released inside the cell, inducing double-strand DNA breakage and subsequent cell death. In June 2017, the EMA granted inotuzumab ozogamicin approval as monotherapy for the treatment of adults with relapsed or refractory CD22-positive B-cell precursor acute lymphoblastic leukaemia (ALL)...

The CD24 cell surface receptor promotes apoptosis in developing B cells, and we recently found that it induces B cells to release plasma membrane-derived, CD24-bearing microvesicles (MVs). Here we have performed a systematic characterization of B cell MVs released from WEHI-231 B lymphoma cells in response to CD24 stimulation. We found that B cells constitutively release MVs of approximately 120 nm, and that CD24 induces an increase in phosphatidylserine-positive MV release. RNA cargo is predominantly comprised of 5S rRNA, regardless of stimulation; however, CD24 causes a decrease in the incorporation of protein coding transcripts...

Hypomorphic mutations in the genes encoding the MRE11/RAD50/NBS1 (MRN) DNA repair complex lead to cancer-prone syndromes. MRN binds DNA double strand breaks where it functions in repair and triggers cell cycle checkpoints via activation of the ataxia-telangiectasia mutated (ATM) kinase. To gain understanding of MRN in cancer, we engineered mice with B lymphocytes lacking MRN, or harboring MRN in which MRE11 lacks nuclease activities. Both forms of MRN deficiency led to hallmarks of cancer, including oncogenic translocations involving c-Myc and the immunoglobulin locus...

Despite recent advances in lymphoma treatment, mantle cell lymphoma (MCL) remains incurable and we are still unable to identify patients who will not benefit from the current standard-of-care. Here, we explore the prognostic value of recurrent genetic aberrations in diagnostic bone marrow (BM) specimens from 183 younger MCL patients from the Nordic MCL2 and MCL3 trials, which represent current standard-of-care regimens. In the univariate model, mutations of TP53 (11%) and NOTCH1 (4%), and deletions of TP53 (16%) and CDKN2A (20%) were significantly associated with inferior outcomes (together with MIPI, MIPI-c, Blastoid morphology and Ki67>30%); however, in multivariate analyses only TP53 mutations (HR=6...

Primary bone (PB) diffuse large B-cell lymphoma (DLBCL) is rare and has a favorable prognosis, but the underlying biological mechanisms remain unknown. In this study we analyzed the clinicopathologic features of 160 patients with PB-DLBCL in comparison with 499 nonosseous DLBCL. Compared with patients with nonosseous DLBCL and secondary involvement of bone by DLBCL, PB-DLBCL patients less frequently had elderly age, B-symptoms, elevated serum lactate dehydrogenase levels, and high International Prognostic Index at diagnosis, more frequently had germinal center (GC) subtype (approximately 90%) and complete remission, and had significantly better survival...

Among several genetic alterations involved in the progression of prostate cancer, B cell lymphoma gene number 2 (BCL-2) is an important target molecule in the progression of androgen-independent prostate cancer (AIPC) after androgen ablation or castration. Nevertheless, the molecular mechanism of BCL-2 in prostate cancer progression remains elusive and controversial. In the current review, we discuss the critical role of BCL-2 in the carcinogenesis of prostate cancer with experimental evidences on the BCL-2 molecular networks in AIPC and androgen-dependent prostate cancer (ADPC) and subsequently suggest perspective research targeting BCL-2...

Lymphangioma is a rare, benign mesenchymal neoplasm, which is characterized by numerous intercommunicating cystic spaces containing lymphatic fluid. It is considered a congenital disease resulting from the obstruction of regional lymph drainage during the developmental period. Lymphangioma frequently occurs in the cervical neck and axilla, also in the retroperitoneum, mediastinum, mesentery, omentum, colon, and pelvis, rarely in the perirenal space. These tumors usually present in childhood, but infrequently, these also present in adults...
