The effect of body mass index at diagnosis on survival of patients with squamous cell head and neck carcinoma.

The aim of this study is to investigate the prognostic role of body mass index (BMI) on survival from head and neck cancer (HNC). We performed a pooled analysis of studies included in the International Head and Neck Cancer Epidemiology consortium. We used Cox proportional hazards models to estimate the adjusted hazard ratios (HR) for overall survival and HNC-specific survival, and we stratified the results according to cancer site.

The PRO-ACTIVE trial protocol: a randomized study comparing the effectiveness of PROphylACTic swallow InterVEntion for patients receiving radiotherapy for head and neck cancer.

Background: Swallowing therapy is commonly provided as a treatment to lessen the risk or severity of dysphagia secondary to radiotherapy (RT) for head and neck cancer (HNC); however, best practice is not yet established. This trial will compare the effectiveness of prophylactic (high and low intensity) versus reactive interventions for swallowing in patients with HNC undergoing RT.

Methods: This multi-site, international randomized clinical trial (RCT) will include 952 adult patients receiving radiotherapy for HNC and who are at high risk for post-RT dysphagia.

Longitudinal Assessment of Frailty and Quality of Life in Patients Undergoing Head and Neck Surgery.

Objective: To understand changes in frailty and quality of life (QOL) in frail versus non-frail patients undergoing surgery for head and neck cancer (HNC).

Methods: Prospective cohort study of patients (median age 67 (50, 88)) with HNC undergoing surgery from December 2011 to April 2014. Fried's Frailty Index, Vulnerable Elders Survey (VES-13), and comprehensive QOL assessments (EORTC QLQ-C30 and HN35) were completed at baseline and 3, 6, and 12-month post-operative visits.

Long-term survival of head and neck squamous cell carcinoma after bone marrow transplant.

Purpose: The risk of developing head and neck squamous cell carcinoma (HNSCC) in patients with graft versus host disease (GVHD) after bone marrow transplant (BMT) is well established but large series reporting outcomes are sparse.

Methods: Retrospective, single institution, study of patients with GVHD and HNSCC after BMT, between January 1, 1968, and June 30, 2016.

Results: In total, 25 patients were studied, of which 21 (84%) were male and 4 (16%) were female.

Extensive Unpredictable Pancreas Cancer Inter-fraction Motion: A Case Report.

We present a case of locally advanced pancreatic cancer with duodenal invasion treated with consolidative chemoradiation, where extensive unpredictable interfraction motion was observed. Initially, two attempts were made to treat with volumetric modulated arc therapy technique. However, due to substantial interfractional motion of the pancreatic head mass relative to the regional nodal areas, the patient was eventually replanned and treated with a four-field box technique.

VEGFR-2 is downregulated in sestamibi-negative parathyroid adenomas.

Background: The purpose of this study was to determine the expression profile of several biomarkers in sestamibi-positive (n = 23) and sestamibi-negative (n = 6) parathyroid adenomas.

Methods: A tissue microarray of parathyroid adenomas from 29 patients was constructed and slides were stained for several proteins involved in angiogenesis, inflammation, cell adhesion, cell cycle, apoptosis, and with markers of the sonic hedgehog, mTOR, Forkhead box O and WNT signal transduction pathways. Protein expression was determined using an image-analysis software (Spectrum Plus©, 38 Aperio).

Papillary Thyroid Cancers with Focal Tall Cell Change are as Aggressive as Tall Cell Variants and Should Not be Considered as Low-Risk Disease.

Background: The tall cell variant of papillary thyroid carcinoma (PTC) is as an aggressive histological variant. The proportion of tall cells needed to influence prognosis is debated.

Methods: Patients with PTC and tall cells, defined as having a height-to-width ratio of ≥ 3:1, seen at a high-volume center between 2001 and 2015, were reviewed.

Impact of immigration status on health behaviors and perceptions in cancer survivors.

Background: Health behaviors including smoking cessation, physical activity (PA), and alcohol moderation are key aspects of cancer survivorship. Immigrants may have unique survivorship needs. We evaluated whether immigrant cancer survivors had health behaviors and perceptions that were distinct from native-born cancer survivors.

Interferon-α-induced retinopathy in chronic hepatitis C treatment: summary, considerations, and recommendations.

Interferons are cytokines that regulate the host's response to viral infection, particularly in the setting of the immunologic response to the hepatitis C virus (HCV). While the virus has the ability to evade the host's innate and specific immunity, exogenous interferon-α with combined ribavirin, treatments have been found to achieve a significant sustained viral response in subgroups of patients with chronic HCV. One of the major side effects of interferon-α is an ocular retinopathy characterized by flame-shaped hemorrhages and cotton wool spots visualized on funduscopic examination.

Patterns, perceptions and their association with changes in alcohol consumption in cancer survivors.

Continued consumption of alcohol after a cancer diagnosis is associated with poorer outcomes. We evaluated whether perceptions of the effects of continued alcohol use and receiving information on moderating alcohol reduced alcohol consumption in adult cancer survivors. A total of 509 cancer survivors were cross-sectionally surveyed at follow-up for their alcohol use before and after cancer diagnosis and perceptions of continued drinking.

Genetic Variations and Cisplatin Nephrotoxicity: A Systematic Review.

Nephrotoxicity is a notable adverse effect in cisplatin treated patients characterized by tubular injury and/or increased serum creatinine (SCr) with incidence varying from 20 to 70%. Pharmacogenomics has been shown to identify strongly predictive genetic markers to help determine which patients are more likely to experience, for example, a serious adverse drug reaction or receive optimal benefit through enhanced efficacy. Genetic variations have been reported to influence the risk of cisplatin nephrotoxicity; however, a comprehensive overview is lacking.

Algorithms Used in Ovarian Cancer Detection: A Minireview on Current and Future Applications.

Background: Ovarian cancer is the 5th most common cause of cancer death among women in the US. Currently, there is no screening algorithm for asymptomatic women that has been shown to lower mortality rates. Screening is currently not recommended and has been shown to increase harm.

Refinement of high-risk endometrial cancer classification using DNA damage response biomarkers: a TransPORTEC initiative.

The TransPORTEC consortium previouslclassified high-risk endometrial cancer including poor-risk histologies such as clear cells, into four molecular subtypes "POLE mutated," "microsatellite unstable," "TP53 mutated," and "no specific molecular profile." We evaluated whether DNA damage response biomarkers could further refine this high-risk tumors classification, in particular the heterogeneous "no specific molecular profile" and "TP53 mutated" subsets recently qualified as poor prognosis in high-risk endometrial cancer. DNA damage response biomarkers including proteins involved in DNA damage (δ-H2AX), homologous recombination (RAD51), regulators of error-prone Non Homologous End-Joining (DNA-pk, FANCD2), and PARP-1 were evaluated in 116 high-risk tumors by immunohistochemistry.

Long-Term Quality of Life of Retroperitoneal Sarcoma Patients Treated with Pre-Operative Radiotherapy and Surgery.

Purpose: Retroperitoneal sarcomas (RPS) are connective tissue cancers that are often large and anatomically in close proximity to critical and radiation-sensitive normal structures and organs within the abdomen and pelvis. The management of RPS may include preoperative radiotherapy (RT) and surgery. We aimed to examine how treatment-related toxicities affect patient quality of life (QOL).

Markers of the p53 pathway further refine molecular profiling in high-risk endometrial cancer: A TransPORTEC initiative.

Background: The morphological classification of high-risk endometrial cancer is of limited prognostic value. Recent attempts to stratify tumours according to molecular signatures have shown considerable promise. Here we attempted to further refine molecular classifications using markers of the p53 pathway.

Determining Patient Preferences for Indeterminate Thyroid Nodules: Observation, Surgery or Molecular Tests.

Background: Gene-expression classifiers (GEC) and genetic mutation panels (GMP) have been shown to improve preoperative diagnostic evaluations of indeterminate thyroid nodules. Despite the improvement, uncertainty regarding the proper management exists. Patient preferences may better inform the management of these indeterminate thyroid nodules.

Relationship between physician-adjudicated adverse events and patient-reported health-related quality of life in a phase II clinical trial (NCT01143402) of patients with metastatic uveal melanoma.

Purpose: Clinical trials commonly use physician-adjudicated adverse event (AE) assessment via the common terminology criteria for adverse events (CTCAE) for decision-making. Patient-reported health-related quality of life (HRQoL) data are becoming more frequent in oncology; however, the relationship between physician-adjudicated AE assessment and HRQoL is understudied.

Methods: Data from a phase II trial (clinicaltrials.

Hypoxia Marker GLUT-1 (Glucose Transporter 1) is an Independent Prognostic Factor for Survival in Bladder Cancer Patients Treated with Radical Cystectomy.

Background: Tumour hypoxia, which is frequent in many cancer types, is associated with treatment resistance and poor prognosis. The role of hypoxia in surgically treated bladder cancer (BC) is not well described. We studied the role of hypoxia in two independent series of urothelial bladder cancers treated with radical cystectomy.

The impact of brain metastasis on quality of life, resource utilization and survival in patients with non-small-cell lung cancer.

This systematic review aims to improve understanding of the burden of disease associated with brain metastases from non-small-cell lung cancer (NSCLC) in terms of survival, quality of life (QoL) and economic impact. PubMed/MEDLINE, Cochrane collaboration and EMBASE databases were searched for articles published in English from 2000 to 2014. Of 3288 abstracts retrieved, 3156 were eliminated without a full-text review.

Polymorphisms of the FOXF1 and MHC locus genes in individuals undergoing esophageal acid reflux assessments.

Gastroesophageal reflux disease (GERD) may lead to Barrett's esophagus (BE). Previously, a large genome-wide association study found two germline markers to be associated with BE, FOXF1 rs9936833 (C allele) and MHC rs9257809 (A allele). This study evaluated whether these two polymorphisms are associated with gastroesphageal acid reflux as measured by 24-hour pH testing.

Improved accuracy of quantitative parameter estimates in dynamic contrast-enhanced CT study with low temporal resolution.

Purpose: A previously proposed method to reduce radiation dose to patient in dynamic contrast-enhanced (DCE) CT is enhanced by principal component analysis (PCA) filtering which improves the signal-to-noise ratio (SNR) of time-concentration curves in the DCE-CT study. The efficacy of the combined method to maintain the accuracy of kinetic parameter estimates at low temporal resolution is investigated with pixel-by-pixel kinetic analysis of DCE-CT data.

Methods: The method is based on DCE-CT scanning performed with low temporal resolution to reduce the radiation dose to the patient.

Prognostic significance of L1CAM expression and its association with mutant p53 expression in high-risk endometrial cancer.

Studies in early-stage, predominantly low- and intermediate-risk endometrial cancer have demonstrated that L1 cell adhesion molecule (L1CAM) overexpression identifies patients at increased risk of recurrence, yet its prognostic significance in high-risk endometrial cancer is unclear. To evaluate this, its frequency, and the relationship of L1CAM with the established endometrial cancer biomarker p53, we analyzed the expression of both markers by immunohistochemistry in a pilot series of 116 endometrial cancers (86 endometrioid, 30 non-endometrioid subtype) with high-risk features (such as high tumor grade and deep myometrial invasion) and correlated results with clinical outcome. We used The Cancer Genome Atlas (TCGA) endometrial cancer series to validate our findings.

White and Gray Matter Abnormalities After Cranial Radiation in Children and Mice.

Purpose: Pediatric patients treated with cranial radiation are at high risk of developing lasting cognitive impairments. We sought to identify anatomical changes in both gray matter (GM) and white matter (WM) in radiation-treated patients and in mice, in which the effect of radiation can be isolated from other factors, the time course of anatomical change can be established, and the effect of treatment age can be more fully characterized. Anatomical results were compared between species.
