Chronic pain patients frequently report memory and concentration difficulties. Objective testing in this population points to poor performance on memory and cognitive tests, and increased comorbid anxiety and depression. Recent evidence has suggested convergence between chronic pain and memory deficits onto the hippocampus.

Introduction: The Alliance A041202/CCTG CLC.2 trial demonstrated superior progression-free survival with ibrutinib-based therapy compared to chemoimmunotherapy with bendamustine-rituximab (BR) in previously untreated older patients with chronic lymphocytic leukemia. We completed a prospective trial-based economic analysis of Canadian patients to study the direct medical costs and quality-adjusted benefit associated with these therapies.

Background: Cost-effectiveness analyses embedded within randomized trials allow for evaluation of value alongside conventional efficacy outcomes; however, collection of resource utilization data can require considerable trial resources.

Methods: We re-analyzed the results from four phase III Canadian Cancer Trials Group trials that embedded cost-effectiveness analyses to determine the impact of minimizing potential cost categories on the incremental cost-effectiveness ratios. For each trial, we disaggregated total costs into component incremental cost categories and recalculated incremental cost-effectiveness ratios using (1) only the top 3 cost categories, (2) the top 5 cost categories, and (3) all cost components.

Lung cancer resulted in an estimated 1.8 million deaths worldwide in 2018 and approximately 20% of patients with non-small cell lung cancer (NSCLC) are diagnosed with stage III unresectable disease. Phase III data from the PACIFIC trial show significantly improved progression-free survival for the checkpoint-inhibitor durvalumab given as consolidation following definitive chemoradiotherapy (cCRT).

Background: Lung cancer is the most common cause of cancer-related death among males and the second leading cause among females globally. Checkpoint inhibitors re-engage the immune system to fight cancer. This review evaluates phase III data on the use of checkpoint inhibitors in the treatment of advanced NSCLC and addresses PD-L1 expression in predicting efficacy.

Article Synopsis
  • - Fatigue is a significant issue for thyroid cancer survivors, with about 41.4% experiencing moderate to severe levels of fatigue, as measured by the Brief Fatigue Inventory (BFI).
  • - The study involved a survey of 205 thyroid cancer patients, primarily women (75%), with an average age of 52.5 years and 6.8 years post-surgery.
  • - Factors like unemployment and lower levels of physical activity were found to be linked to higher fatigue levels, suggesting that increasing physical activity may help mitigate this fatigue in survivors.

Introduction: The current WHO classification of lung cancer states that a diagnosis of SCLC can be reliably made on routine histological and cytological grounds but immunohistochemistry (IHC) may be required, particularly (1) in cases in which histologic features are equivocal and (2) in cases in which the pathologist wants to increase confidence in diagnosis. However, reproducibility studies based on hematoxylin and eosin-stained slides alone for SCLC versus large cell neuroendocrine carcinoma (LCNEC) have shown pairwise κ scores ranging from 0.35 to 0.

In an era of reduced peer-reviewed grant funding, performing academic bone oncology-related research has become increasingly challenging. Over the last 10 years we have held an annual meeting to bring together clinicians, clinician/scientists and basic biomedical researchers interested in the effects of cancer and its treatment on skeletal tissues. In the past these "Bone and the Oncologist New Updates Conference (BONUS)" meetings have served as critical catalyst for initiating productive research collaborations between attendees.

Purpose: Non-small-cell lung cancer (NSCLC) is globally prevalent and associated with high rates of mortality. Immune checkpoint pathways are often exploited by tumors to evade immunity-mediated destruction, and checkpoint inhibitors can reactivate tumor-related immune responses. This review considers available clinical evidence for the use of checkpoint inhibitors in the treatment of second-line advanced NSCLC.

Background: Few prognostic models for overall survival (OS) are available for patients with metastatic castration-resistant prostate cancer (mCRPC) treated with recently approved agents. We developed a prognostic index model using readily available clinical and laboratory factors from a phase III trial of abiraterone acetate (hereafter abiraterone) in combination with prednisone in post-docetaxel mCRPC.

Patients And Methods: Baseline data were available from 762 patients treated with abiraterone-prednisone.

Purpose: Gene fusions leading to androgen receptor-modulated ERG overexpression occur in up to 70% of metastatic castration-resistant prostate cancers (mCRPC). We assessed the association between ERG rearrangement status and clinical benefit from abiraterone acetate.

Experimental Design: COU-AA-302 is a phase III trial comparing abiraterone acetate and prednisone versus prednisone in chemotherapy-naïve mCRPC.

Introduction: Choosing adjuvant radiotherapy (RT) or salvage RT after radical prostatectomy (RP) for locally advanced prostate cancer is controversial. Performing RT early after RP may increase the risk of urinary complications compared to RT performed later. We evaluated the urinary complication rates of men treated with surgery followed by early or late RT.

Background: Tremelimumab (CP-675,206) is a fully human monoclonal antibody binding to cytotoxic T-lymphocyte-associated antigen 4 (CTLA4) on T cells that stimulates the immune system by blocking the CTLA4-negative regulatory signal. Combination with standard chemotherapy may strengthen antitumor therapy. This is a phase Ib, multisite, open-label, nonrandomized dose escalation trial evaluating the safety, tolerability, and maximum tolerated dose (MTD) of tremelimumab combined with gemcitabine in patients with metastatic pancreatic cancer.

Background: Limited penetration of anticancer drugs in solid tumours is a probable cause of drug resistance. Our previous results indicate that drug penetration depends on cellular packing density and adhesion between cancer cells.

Methods: We used epithelioid and round cell variants of the HCT-8 human colon carcinoma cell lines to generate tightly and loosely packed xenografts in nude mice.

Molecularly targeted agents are commonly used in oncology practice, and many new targeted agents are currently being tested in clinical trials. Although these agents are thought to be more specific and less toxic then traditional cytotoxic chemotherapy, they are associated with a variety of toxicities, including ocular toxicity. Many of the molecules targeted by anticancer agents are also expressed in ocular tissues.
