RATIONALE: T-cell lymphoma is a neoplasm that expresses markers of T-cell or natural killer cell (NK)-origin but not those of B-cell origin. Although B-cell lymphoma with abundant expression of T-cell markers exist, the opposite is very rare. Therefore, little is known about this subtype of lymphoma, including its treatment and prognosis. CASE REPORT: A 65-year-old man was diagnosed with T-cell lymphoma with abundant CD20 expression. He was refractory to cyclophosphamide + epirubicin + vincristine + prednisone + etoposide (CHOPE), ifosfamide + cisplatin + etoposide + dexamethasone (DICE), and hyper-cyclophosphamide + vincristine + epirubicin + dexamethasone (CVAD) chemotherapy...

Vincristine is one of the most common anticancer drugs clinically employed in the treatment of various malignancies. A major side effect associated with vincristine is the development of neuropathic pain, which is not readily relieved by available analgesics. Although efforts have been made to identify the pathogenesis of vincristine-induced neuropathic pain, the mechanisms underlying its pathogenesis have not been fully elucidated. In the present study, a neuropathic pain model was established in Sprague-Dawley rats by intraperitoneal injection of vincristine sulfate...

Drug repurposing is the use of known drugs for new indications. Malignant pleural mesothelioma (MPM) is a rare cancer with a poor prognosis. So far, few treatments have been approved in this disease. However, its incidence is expected to increase significantly, particularly in developing countries. Consequently, drug repurposing appears as an attractive strategy for drug development in MPM, since the known pharmacology and safety profile based on previous approvals of repurposed drugs allows for faster time-to-market for patients and lower treatment cost...

Mutations in the cereblon ( CRBN ) gene cause human intellectual disability, one of the most common cognitive disorders. However, the molecular mechanisms of CRBN -related intellectual disability remain poorly understood. We investigated the role of CRBN in synaptic function and animal behavior using male mouse and Drosophila models. Crbn knockout (KO) mice showed normal brain and spine morphology as well as intact synaptic plasticity; however, they also exhibited decreases in synaptic transmission and presynaptic release probability exclusively in excitatory synapses...

A 40-year-old female presented with a skin rash, hepatosplenomegaly, hypothyroidism, IgG-λ monoclonal gammopathy, slightly elevated serum VEGF levels, and >1-year history of weakness in the posterior cervical muscles. Based on these symptoms and her clinical course, she was suspected of having POEMS syndrome. However, because there was no sign of peripheral neuropathy (PN), the criteria for the diagnosis of POEMS syndrome were not met. Consequently, she continued follow-up and was under close observation as an outpatient...

BACKGROUND: Multiple myeloma (MM) is a plasma cell tumour with an approximate annual incidence of 4500 in the UK. Therapeutic options for patients with MM have changed in the last decade with the arrival of proteasome inhibitors and immunomodulatory drugs. Despite these options, almost all patients will relapse post first-line autologous stem cell transplantation (ASCT). First relapse management (second-line treatment) has evolved in recent years with an expanding portfolio of novel agents, driving response rates influencing the durability of response...

In the present study, we successfully developed a docetaxel (DTX) and thalidomide (TDD) co-delivery system based on low density lipoprotein (LDL) modified silica nanoparticles (LDL/SLN/DTX/TDD). By employing the tumor homing property of LDL and the drug-loading capability of silica nanoparticles, the prepared LDL/SLN/DTX/TDD was expected to locate and specifically deliver the loaded drugs (DTX and TDD) to achieve effective chemotherapy of liver cancer. In vitro analysis revealed that nano-sized LDL/SLN/DTX/TDD with decent drug loading capabilities was able to increase the delivery efficiency by targeting the low density lipoprotein receptors, which were overexpressed on HepG2 human hepatocellular liver carcinoma cell line, which exerted better cytotoxicity than unmodified silica nanoparticles and free drugs...

Unresectable or metastatic (advanced) primary pulmonary carcinoma (PPC) represents a therapeutic challenge where surgery may be contraindicated and the therapeutic role of maximum-tolerated dose (MTD) chemotherapy remains uncertain. This study was undertaken to explore the impact of metronomic chemotherapy (MC) in dogs with advanced PPC. Previously untreated dogs with advanced (T3 or N1 or M1) PPC, with complete staging work-up and follow-up data, receiving MC (comprising low-dose cyclophosphamide, piroxicam and thalidomide), surgery, MTD chemotherapy or no oncologic treatment were eligible for inclusion...

PURPOSE OF REVIEW: Multiple myeloma treatment regimens consist of proteasome inhibitors (bortezomib, carfilzomib, and ixazomib), immunomodulatory drugs (thalidomide, lenalidomide, and pomalidomide), and steroids. In this paper, we will review the pathophysiology and associated cardiotoxicities of the different multiple myeloma therapeutic modalities and present methods to mitigate the development of cardiovascular complications. RECENT FINDINGS: Although proteasome inhibitors and immunomodulatory drugs have led to significant improvements in oncologic outcomes, there is increasing evidence of serious cardiovascular side effects which may be exacerbated in the setting of underlying cardiovascular risk factors or disease...

The effect of immunomodulatory drugs (IMiDs) on serious infection remains uncertain. We therefore conducted a systematic review and meta-analysis to assess the possible impact of IMiDs on serious infection in patients with multiple myeloma (MM). We searched randomized controlled trials (RCTs) and observational studies from databases that addressed the effect of IMiDs on serious infection in patients with MM. We pooled data from RCTs and observational studies separately and used the GRADE approach to rate the quality of evidence...

We have previously shown that immunomodulatory drug (IMiD) compounds induce a shift into immature myeloid precursors with a maturational arrest and subsequent neutropenia. The mechanism of action is unknown. Here we found that IMiD compounds cause selective ubiquitination and degradation of the transcription factor IKZF1 in CD34+ cells by the Cereblon (CRBN) E3 ubiquitin ligase. Loss of IKZF1 is associated with a decrease of the IKZF1-dependent transcription factor PU.1, critical for the development and maturation of neutrophils...
