The impact of population-based EGFR testing in non-squamous metastatic non-small cell lung cancer in Alberta, Canada.

Objectives: While Epidermal Growth Factor Receptor (EGFR) Tyrosine Kinase Inhibitors have been shown to be effective in phase III randomized trials, the value of targeted therapies has been challenging to evaluate at the population-level. We examined the impact of population-level EGFR testing and treatment on survival outcomes among non-squamous metastatic Non-Small Cell Lung Cancer (NSCLC) patients.

Materials And Methods: Real-world, population-level data were collected from all de novo non-squamous metastatic NSCLC patients in Alberta, Canada from 2004 to 2020.

Combined CCNE1 high-level amplification and overexpression is associated with unfavourable outcome in tubo-ovarian high-grade serous carcinoma.

CCNE1 amplification is a recurrent alteration associated with unfavourable outcome in tubo-ovarian high-grade serous carcinoma (HGSC). We aimed to investigate whether immunohistochemistry (IHC) can be used to identify CCNE1 amplification status and to validate whether CCNE1 high-level amplification and overexpression are prognostic in HGSC. A testing set of 528 HGSC samples stained with two optimised IHC assays (clones EP126 and HE12) was subjected to digital image analysis and visual scoring.

Canadian Cancer Trials Group (CCTG) IND211: A randomized trial of pelareorep (Reolysin) in patients with previously treated advanced or metastatic non-small cell lung cancer receiving standard salvage therapy.

Objectives: Pelareorep (reolysin), a Dearing strain of reovirus serotype 3, has demonstrated oncolytic activity as single agent and synergy with chemotherapy. We evaluated pelareorep, combined with standard second-line chemotherapy in patients with non-small cell lung cancer (NSCLC).

Materials And Methods: This randomized phase II trial enrolled patients with advanced or metastatic NSCLC after first line chemotherapy.

Identification of the SUMO E3 ligase PIAS1 as a potential survival biomarker in breast cancer.

Metastasis is the ultimate cause of breast cancer related mortality. Epithelial-mesenchymal transition (EMT) is thought to play a crucial role in the metastatic potential of breast cancer. Growing evidence has implicated the SUMO E3 ligase PIAS1 in the regulation of EMT in mammary epithelial cells and breast cancer metastasis.

Repurposing Sunitinib with Oncolytic Reovirus as a Novel Immunotherapeutic Strategy for Renal Cell Carcinoma.

Purpose: In addition to their direct cytopathic effects, oncolytic viruses are capable of priming antitumor immune responses. However, strategies to enhance the immunotherapeutic potential of these agents are lacking. Here, we investigated the ability of the multi-tyrosine kinase inhibitor and first-line metastatic renal cell carcinoma (RCC) agent, sunitinib, to augment the antitumor immune response generated by oncolytic reovirus.

Data collection, processing, validation, and verification.

The collection, processing, validation, verification, formatting, filing, and storage of the required input data are some of the most important components in the National Institute for Occupational Safety and Health (NIOSH) Radiation Dose Reconstruction Program. Without question, the quality and scientific validity of the reconstructed dose estimates are totally dependent on these aspects of the program. Of equal importance is that the data be filed not only in a readily accessible format, but also in one that facilitates error-free retrievability.

Upfront double high-dose chemotherapy with DICEP followed by BEAM and autologous stem cell transplantation for poor-prognosis aggressive non-Hodgkin lymphoma.

A single center, prospective clinical trial was conducted evaluating 2 cycles of induction high-dose chemotherapy for adults younger than 65 years of age with aggressive non-Hodgkin lymphoma (NHL) and 2 to 3 Age-Adjusted International Prognostic Index risk factors. Patients received one cycle of standard dose cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) followed by one cycle of dose-intensive cyclophosphamide 5.25 g/m(2), etoposide 1.

Individualized quality of life, standardized quality of life, and distress in patients undergoing a phase I trial of the novel therapeutic Reolysin (reovirus).

Background: The purpose of this study was to evaluate the individualized and standardized quality of life (QL) and psychological distress of patients participating in a Phase I trial of the novel therapeutic reovirus (Reolysin).

Methods: 16 patients with incurable metastatic cancer were interviewed prior to being accepted into the phase I trial with a semi-structured expectations interview, the Schedule for the Evaluation of Individual Quality of Life--Direct Weighting (SEIQoL-DW), the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30), the Brief Symptom Inventory (BSI), the Beck Depression Inventory (BDI), and the Spiritual Health Inventory (SHI).

Results: Patients were able to complete all measures.

Lymphomas and oncolytic virus therapy.

There are several well-documented cases in medical literature of the remission of leukemias and malignant lymphomas following natural human viral infections. In the hope of being able to reproduce these spontaneous tumor regressions, investigators have studied various viruses with distinct oncolytic properties. The first attempts to treat patients with oncolytic viruses took place > 80 years ago; however, it achieved little success.

Reovirus oncolysis as a novel purging strategy for autologous stem cell transplantation.

Hematologic stem cell rescue after high-dose cytotoxic therapy is extensively used for the treatment of many hematopoietic and solid cancers. Gene marking studies suggest that occult tumor cells within the autograft may contribute to clinical relapse. To date purging of autografts contaminated with cancer cells has been unsuccessful.
