A Short Course of Standard Velcade/Dexamethasone Followed by Unlimited Weekly Maintenance Therapy Is an Effective Treatment in Relapsed/Refractory Multiple Myeloma.

Background: Bortezomib (B), known as Velcade, is a reversible proteasome inhibitor approved for relapsed/refractory multiple myeloma (RRMM) patients (pts). The standard of care protocol includes eight cycles of intravenous push (IVP) injections of B and oral dexamethasone (D), which increases the toxicity. Here, we describe the results of an open-label, phase II clinical trial employing only four cycles of B/D.

Cholesterol crystals induce mechanical trauma, inflammation, and neo-vascularization in solid cancers as in atherosclerosis.

Background And Aims: Cancer and atherosclerosis share common risk factors and inflammatory pathways that promote their proliferation via vascular endothelial growth factor (VEGF). Because CCs cause mechanical injury and inflammation in atherosclerosis, we investigated their presence in solid cancers and their activation of IL-1β, VEGF, CD44, and Ubiquityl-Histone H2B (Ub-H2B), that promote cancer growth.

Methods: Tumor specimens from eleven different types of human cancers and atherosclerotic plaques were assessed for CCs, free cholesterol content and IL1-β by microscopy, immunohistochemistry, and biochemical analysis.

Patient-reported outcomes of patients with myelofibrosis or essential thrombocythemia enrolled in the MOST study.

The Myelofibrosis and Essential Thrombocythemia Observational STudy (MOST; NCT02953704) is an ongoing, noninterventional study assessing clinical characteristics and patient-reported outcomes (PROs) of patients with myelofibrosis (MF) or essential thrombocythemia (ET). This analysis assessed PROs at enrollment; symptom burden and quality of life (QoL), work productivity, and activity were assessed using validated questionnaires in patients with low- or intermediate-1-risk (age-alone) MF, or high- or low-risk ET (receiving ET-directed therapy) at enrollment. In MF and ET cohorts, fatigue had highest mean symptom score.

Small Molecule 20S Proteasome Enhancer Regulates MYC Protein Stability and Exhibits Antitumor Activity in Multiple Myeloma.

Despite the addition of several new agents to the armamentarium for the treatment of multiple myeloma (MM) in the last decade and improvements in outcomes, the refractory and relapsing disease continues to take a great toll, limiting overall survival. Therefore, additional novel approaches are needed to improve outcomes for MM patients. The oncogenic transcription factor MYC drives cell growth, differentiation and tumor development in many cancers.

Phase Ib/II Clinical Trial of Pembrolizumab With Bevacizumab for Metastatic Renal Cell Carcinoma: BTCRC-GU14-003.

Purpose: We hypothesized that bevacizumab will potentiate activity of pembrolizumab. We conducted a phase Ib/II, single-arm, multisite clinical trial of the combination in metastatic renal cell carcinoma (RCC).

Patients And Methods: Patients with metastatic clear cell RCC who experienced progression after at least one systemic therapy (phase Ib) or were treatment naïve (phase II) were enrolled.

Phase II, Multicenter, Randomized Trial of Docetaxel plus Prednisone with or Without Cediranib in Men with Chemotherapy-Naive Metastatic Castrate-Resistant Prostate Cancer.

Lessons Learned: The negative results are consistent with the negative results of large phase III trials in which docetaxel plus antiangiogenic agents were used in patients with metastatic castrate-resistant prostate cancer (mCRPC).The negative data underscore that, despite a sound biological rationale and supportive early-phase clinical results, adding antiangiogenic agents to docetaxel for mCRPC is a great challenge.

Background: Inhibition of vascular endothelial growth factor (VEGF) signaling abrogates tumor-induced angiogenesis to constrain tumor growth, and can be exploited therapeutically by using cediranib, an oral tyrosine kinase inhibitor of VEGF receptor signaling.

An overview of the toxicities of checkpoint inhibitors in older patients with cancer.

Checkpoint inhibitors offer an exciting new option for treatment of a wide variety of cancers. By binding to surface receptors or their associated ligands on T cells, this class of drugs enhances immune activation and response to cancer cells. In available studies, the drugs are well tolerated, although toxicity involving skin, gastrointestinal tract, liver, lungs, and endocrine organs has been observed.

Adjuvant Chemotherapy for Stage II Colon Cancer: A Clinical Dilemma.

The decision to treat a patient with stage II colon cancer with adjuvant chemotherapy can be challenging. Although the benefit of treatment is clear in most patients with stage III disease, the decision to provide chemotherapy after surgical resection in stage II disease must be made on an individual basis. Several trials have demonstrated the small but absolute benefits of receiving adjuvant chemotherapy for stage II colon cancer for disease-free survival and overall survival.

Management of locally advanced and metastatic colon cancer in elderly patients.

Colon cancer is the second leading cause of cancer mortality in the United States with a median age at diagnosis of 69 years. Sixty percent are diagnosed over the age of 65 years and 36% are 75 years or older. At diagnosis, approximately 58% of patients will have locally advanced and metastatic disease, for which systemic chemotherapy has been shown to improve survival.

Histone deacetylation : an attractive target for cancer therapy?

Recent research has elucidated another mechanism for gene expression and signalling protein regulation in malignant cells. Histone deacetylases (HDACs) have been associated with silencing of tumour suppressor genes, and with other functions that promote malignant cell phenotype, such as the function of the chaperone protein heat shock protein (HSP)-90. Malignant cells overexpress some HDACs, and aberrant gene products have been shown to recruit HDACs to DNA to accomplish silencing of differentiation in other genes.

BCNU toxicity presenting with a large pericardial and pleural effusion.

Background: Carmustine (BCNU), 1, 3-bis (2-chloroethyl)-1-nitosourea, is an alkylating agent which is commonly used as a part of conditioning regimen for autologous peripheral blood stem cell transplantation. Despite the widespread use of BCNU therapy in adults, cardiopulmonary toxicity presenting with cardiac tamponade has not been reported.

Case Report: We present a patient who received BCNU as part of her conditioning regimen followed by autologous peripheral blood stem cell transplantation.
