Background: EORTC 24971 was a phase III trial demonstrating superiority of induction regimen TPF over PF, in terms of progression-free (PFS) and overall survival (OS) in locoregionally advanced unresectable HNSCC. We conducted a retrospective analysis of prospectively collected data aiming to evaluate whether only HPV(-) patients (pts) benefit from adding docetaxel to PF, in which case de-intensifying induction treatment in HPV(+) pts could be considered. Methods: Pre-therapy tumor biopsies (blocks or slides) were assessed for high-risk HPV by p16 immunohistochemistry, PCR and qPCR...

Genome-wide somatic mutation profiles of tumours can now be assessed efficiently and promise to move precision medicine forward. Statistical analysis of mutation profiles is however challenging due to the low frequency of most mutations, the varying mutation rates across tumours, and the presence of a majority of passenger events that hide the contribution of driver events. Here we propose a method, NetNorM, to represent whole-exome somatic mutation data in a form that enhances cancer-relevant information using a gene network as background knowledge...

Recent advances in high-throughput technologies have given rise to collecting large amounts of multidimensional heterogeneous data that provide diverse information on the same biological samples. Integrative analysis of such multisource datasets may reveal new biological insights into complex biological mechanisms and therefore remains an important research field in systems biology. Most of the modern integrative clustering approaches rely on independent analysis of each dataset and consensus clustering, probabilistic or statistical modeling, while flexible distance-based integrative clustering techniques are sparsely covered...

OBJECTIVES: Exosomes are important mediators in intercellular communications and play a role in cancer progression and metastasis. Exosomal membranes are enriched in endosome-specific tetraspanins (CD9 and CD63). Here, we explored the expression of CD63 and CD9 utilizing immunohistochemistry in malignant and nonmalignant cells in 29 resected pancreatic specimens (RPSs) of mixed racial background. METHODS: The pathologic tissues (PTs) and adjacent normal tissues (ANTs) in each RPS were stained for CD63 and CD9...

BACKGROUND: The Caribbean ranks seventh among world regions most affected by cervical cancer. Social health inequalities, such as differences in access to screening services, engender disparities in incidence and mortality between low- and middle-income countries and industrialized countries. The French National Cancer Plan 2014-2019 focuses on reducing inequalities in cervical cancer. OBJECTIVE: The aim of this study was to describe the geographical distribution and overall survival of cervical cancer, based on data from a population-based cancer registry in Martinique (French West-Indies)...

BACKGROUND: Colorectal cancer (CRC) is prevalent in the older population, and surgery is the mainstay in curative treatment. A preoperative geriatric assessment (GA) can identify frail older patients at risk for developing postoperative complications. In this randomised controlled trial we wanted to investigate whether tailored interventions based on a preoperative GA could reduce the frequency of postoperative complications in frail patients operated for CRC. METHODS: Patients >65 years scheduled for elective CRC surgery and fulfilling predefined criteria for frailty were randomised to either a preoperative GA followed by a tailored intervention, or care as usual...

Brain metastases (BMs) are the most common intracranial malignancy and afflict ~10%-20% of patients with cancer. BMs tend to present at the boundaries of gray and white matter because of the distribution of small vessels. In addition, metastases may not be randomly distributed across gross anatomical regions of the brain, but this has not previously been quantified. We retrospectively analyzed a series of 28 patients with recurrent BMs with a total of 150 lesions. Each lesion was manually defined based on T1 gadolinium-enhanced imaging...

Understanding the gene-specific risks for development of breast cancer will lead to improved clinical care for those carrying germline mutations in cancer predisposition genes. We sought to detail the spectrum of mutations and refine risk estimates for known and proposed breast cancer susceptibility genes. Targeted massively-parallel sequencing was performed to identify mutations and copy number variants in 26 known or proposed breast cancer susceptibility genes in 2134 BRCA1/2-negative women with familial breast cancer (proband with breast cancer and a family history of breast or ovarian cancer) from a largely European-Caucasian multi-institutional cohort...

Adipose tissue is involved in the etiology of postmenopausal breast cancer, possibly through increased sex steroid hormone production, inflammation, and altered adipokines. Vitamin D may affect these pathways but its effect on gene expression in different tissues has not been examined. Within a double-blind, 12-month placebo-controlled randomized trial, we compared 2000 IU/day oral vitamin D3 supplementation (N = 39) vs. placebo (N = 40) on the expression of 5 genes in breast and adipose tissue in overweight/obese postmenopausal women (50-75 years)...

Clinical research generally focuses on results involving a statistical mean with little attention in trial design to patients who respond considerably better or worse than average. Exploring the reasons underlying an "atypical response" will increase understanding of the mechanisms involved in cancer progression and treatment resistance, accelerate biomarker identification, and improve precision medicine by allowing clinicians to prospectively select optimal treatments. Based on our review, we suggest two ways to move this field forward...

Patients with hepatocellular carcinomas (HCC) have poor outcomes as a result of late detection of disease. We investigated the possibility of using smell detection by dogs for detecting HCC from breaths of patients. Patients' whose diagnosis of HCC was confirmed histologically or radiologically according to the American Association for the study of the Liver (AASLD) criteria had breaths collected using facemasks and transported to the study test site. One golden retriever was trained to detect HCC with positive feedback using known samples of HCC and healthy controls in a step-wise manner...

Triple-negative breast cancer (TNBC) has an aggressive behavior and limited therapeutic options due to lack of targeted therapy. We aimed in this study to assess the immunohistochemical expression of EGFR and cytokeratin 5/6 and their ability to predict survival and response to neoadjuvant chemotherapy (NAC) among triple-negative breast cancer patients. Thirty-five cases with TNBC were studied by immunohistochemistry for EGFR and CK5/6 expression. Data on overall survival (OS), disease-free survival (DFS) and response to NAC were collected...

Not many models of mammalian cell cycle system exist due to its complexity. Some models are too complex and hard to understand, while some others are too simple and not comprehensive enough. Moreover, some essential aspects, such as the response of G1-S and G2-M checkpoints to DNA damage as well as the growth factor signalling, have not been investigated from a systems point of view in current mammalian cell cycle models. To address these issues, we bring a holistic perspective to cell cycle by mathematically modelling it as a complex system consisting of important sub-systems that interact with each other...

Currently, there is no formal curriculum addressing geriatric oncology within Canadian radiation oncology (RO) residency programs. Knowledge related to geriatric medicine may help radiation oncologists modify RT based on frailty status and geriatric considerations. Understanding specific learning needs allow program coordinators to align the current curriculum with residents' geriatric oncology learning needs. The purpose of this study is to determine the geriatric oncology educational needs of the Canadian RO residents and to inform Canadian RO residency training...
