Ending 40 years of silence: Rationale for a new staging system for soft tissue sarcoma of the head and neck.

The tumor, node, metastases (TNM) anatomic staging system plays a pivotal role in cancer care, research, and cancer control activities. Since the first edition of the American Joint Committee on Cancer TNM staging classification published in 1977, soft tissue sarcomas have been staged in an anatomic site agnostic fashion whereby the primary tumor size (T) was categorized as T1 if <=5 cm and T2 if >5 cm; this remained unchanged through the 7th edition of the TNM. However, soft tissue sarcomas of the head and neck (STSHN) usually present smaller than sarcomas of other sites, but carry a disproportionate risk of local recurrence.

Demonstrating a new approach to planning and monitoring rural medical training distribution to meet population need in North West Queensland.

Background: Improving the health of rural populations requires developing a medical workforce with the right skills and a willingness to work in rural areas. A novel strategy for achieving this aim is to align medical training distribution with community need. This research describes an approach for planning and monitoring the distribution of general practice (GP) training posts to meet health needs across a dispersed geographic catchment.

Evaluation of a local government "shelter and van" intervention to improve safety and reduce alcohol-related harm.

Background: The entertainment precincts of cities, while contributing to local economies, need to be carefully managed to mitigate harms. Individual behaviours and government regulation have typically been the foci of interventions aimed at reducing alcohol-related harm. Little is known about how changes to the built environment might influence alcohol-related harms in these settings.

Predictive markers for anti-PD-1/PD-L1 therapy in non-small cell lung cancer-where are we?

The selection of patients for immunotherapy remains challenging given the lack of highly specific and highly sensitive biomarkers. Nevertheless, it is essential that testing laboratories are able to fulfil licencing criteria by providing the tests which have been validated as providing useful predictive information. Programmed cell death protein 1 (PD-1) expression assessment is now established in routine practice, although the situation regarding the selection of a particular assay remains complex, and testing protocols are likely to change in future.

Data Set for the Reporting of Carcinomas of the Nasopharynx and Oropharynx: Explanations and Recommendations of the Guidelines From the International Collaboration on Cancer Reporting.

The International Collaboration on Cancer Reporting was established to internationally unify and standardize the pathologic reporting of cancers based on collected evidence, as well as to allow systematic data collection across institutions and countries to guide cancer care in the future. An expert panel was convened to identify the minimum data set of elements that should be included in cancer reporting from tumors of the nasopharynx and oropharynx. Specifically, there has been a significant change in practice as a result of identifying oncogenic viruses, including human papillomavirus and Epstein-Barr virus, because they preferentially affect the oropharynx and nasopharynx, respectively.

F-FDG PET/CT for locoregional surveillance following definitive treatment of head and neck cancer: A meta-analysis of reported studies.

Purpose: To evaluate the performance of F-fluorodeoxy-d-glucose positron emission tomography-computed tomography ( F-FDG PET/CT) in identifying local failure and regional failure following curative radiotherapy or surgery for head and neck squamous cell carcinoma.

Methods: A comprehensive literature search identified studies published between January 2010 and August 2016. Diagnostic performance of F-FDG PET/CT was evaluated for local failure/regional failure stratified by treatment-to-scan time interval of ≤3 versus >3 months.

Vulnerabilities of radiomic signature development: The need for safeguards.

Purpose: Refinement of radiomic results and methodologies is required to ensure progression of the field. In this work, we establish a set of safeguards designed to improve and support current radiomic methodologies through detailed analysis of a radiomic signature.

Methods: A radiomic model (MW2018) was fitted and externally validated using features extracted from previously reported lung and head and neck (H&N) cancer datasets using gross-tumour-volume contours, as well as from images with randomly permuted voxel index values; i.

The interplay of IMRT and transoral surgery in HPV-mediated oropharyngeal cancer: Getting the balance right.

Transoral surgery (TOS) and IMRT represent two primary local ablative treatment modalities for oropharyngeal cancer (OPC). The choice of one over the other represents an interplay between the chance of cure vs risk of late sequelae. HPV-mediated (HPV+) OPC patients generally have excellent outcomes, especially in TNM-8 stage I disease.

Identification and validation of novel microenvironment-based immune molecular subgroups of head and neck squamous cell carcinoma: implications for immunotherapy.

Background: Targeting the immune checkpoint pathway has demonstrated antitumor cytotoxicity in treatment-refractory head and neck squamous cell carcinoma (HNSC). To understand the molecular mechanisms underpinning its antitumor response, we characterized the immune landscape of HNSC by their tumor and stromal compartments to identify novel immune molecular subgroups.

Patients And Methods: A training cohort of 522 HNSC samples from the Cancer Genome Atlas profiled by RNA sequencing was analyzed.

Patient-Derived Xenografts for Prognostication and Personalized Treatment for Head and Neck Squamous Cell Carcinoma.

Overall survival remains very poor for patients diagnosed as having head and neck squamous cell carcinoma (HNSCC). Identification of additional biomarkers and novel therapeutic strategies are important for improving patient outcomes. Patient-derived xenografts (PDXs), generated by implanting fresh tumor tissue directly from patients into immunodeficient mice, recapitulate many of the features of their corresponding clinical cancers, including histopathological and molecular profiles.

Rural training pathways: the return rate of doctors to work in the same region as their basic medical training.

Background: Limited evidence exists about the extent to which doctors are returning to rural region(s) where they had previously trained. This study aims to investigate the rate at which medical students who have trained for 12 months or more in a rural region return to practice in that same region in their early medical career. A secondary aim is to investigate whether there is an independent or additional association with the effect of longer duration of rural exposure in a region (18-24 months) and for those completing both schooling and training in the same rural region.

A cross sectional study in cognitive and neurobehavioral impairment in long-term nasopharyngeal cancer survivors treated with intensity-modulated radiotherapy.

Purpose/objectives: To determine neurocognitive and neurobehavioral impairment in long-term nasopharyngeal cancer survivors (NPC) treated with intensity-modulated radiotherapy (IMRT).

Materials/methods: A cross-sectional cohort of NPC ≥4 years (y) following IMRT was assessed. Objective cognitive function was measured using the Montreal Cognitive Assessment (MoCA) and patient-reported memory was assessed with the MDASI-HN problems remembering item.

Predictors of Early Recurrence Prior to Planned Postoperative Radiation Therapy for Oral Cavity Squamous Cell Carcinoma and Outcomes Following Salvage Intensified Radiation Therapy.

Purpose: To determine predictors and outcomes for oral squamous cell carcinoma (OSCC) patients who had early recurrence before commencement of postoperative radiation therapy (PORT).

Methods: Retrospective review was performed for patients with OSCC treated with PORT between 2003 and 2015 after curative-intent surgery. Early recurrence was defined as tumor recurrence after surgical resection and before initiating planned PORT.

Major Changes in Head and Neck Staging for 2018.

Oncologists should be aware of three major modifications and additions to staging head and neck cancer that became effective in 2018. Oral cavity cancers have the addition of depth of invasion; oropharyngeal cancers (OPCs) are now distinguished by the immunohistochemical stain, p16, into those that are associated with high-risk human papillomavirus and those that are not; and all sites except nasopharyngeal carcinoma and high-risk human papillomavirus OPC will now include the important parameter of extranodal extension. The rationale and emerging data supporting these changes are discussed in this article and the accompanying oral presentation at the 2018 ASCO Annual Meeting.

The Clinicopathological and Molecular Associations of PD-L1 Expression in Non-small Cell Lung Cancer: Analysis of a Series of 10,005 Cases Tested with the 22C3 Assay.

PD-L1 expression testing is mandatory prior to pembrolizumab prescription in non-small cell lung cancer. Our service offers PD-L1 testing using the PD-L1 IHC 22C3 pharmDx assay, in parallel with EGFR, ALK, ROS1 and (in some cases) KRAS testing. We correlate PD-L1 expression in 10,005 tumours with patient age and sex, with tumour histological subtypes, with the sampling modality and type of tissue, and with the presence of other molecular alterations.

The addition of pretreatment plasma Epstein-Barr virus DNA into the eighth edition of nasopharyngeal cancer TNM stage classification.

The eighth edition of the American Joint Committee on Cancer (AJCC)/Union for International Cancer Control (UICC) stage classification (TNM) for nasopharyngeal carcinoma (NPC) was launched. It remains unknown if incorporation of nonanatomic factors into the stage classification would better predict survival. We prospectively recruited 518 patients with nonmetastatic NPC treated with radical intensity-modulated radiation therapy ± chemotherapy based on the eighth edition TNM.

Long-Term Late Toxicity, Quality of Life, and Emotional Distress in Patients With Nasopharyngeal Carcinoma Treated With Intensity Modulated Radiation Therapy.

Radiologic-Pathologic Correlation of Tumor Thickness and Its Prognostic Importance in Squamous Cell Carcinoma of the Oral Cavity: Implications for the Eighth Edition Tumor, Node, Metastasis Classification.

Background And Purpose: Addressing the performance of an imaging-based parameter compared to a "gold standard" pathologic measurement is essential to achieve accurate clinical T-classification. Our aim was to determine the radiologic-pathologic tumor thickness correlation and its prognostic value in oral squamous cell carcinoma.

Materials And Methods: All pathologic T1-T3 (seventh edition of the of the American Joint Committee on Cancer) oral squamous cell carcinomas diagnosed between 2010 and 2015 were reviewed.

Large-Scale EGFR Mutation Testing in Clinical Practice: Analysis of a Series of 18,920 Non-Small Cell Lung Cancer Cases.

We make use of a very large dataset of non-small cell lung cancer specimens to examine the molecular epidemiology of EGFR mutations, particularly with respect to rare and compound mutations, and to non-adenocarcinoma histological subtypes. We also demonstrate the feasibility of large-scale EGFR mutation screening using the full range of specimens encountered in routine practice. We retrospectively reviewed 18,920 unselected EGFR mutation results from our centre between July 2009 and October 2016, using Qiagen's therascreen EGFR RGQ PCR Kit.

Creating Low-Cost 360-Degree Virtual Reality Videos for Hospitals: A Technical Paper on the Dos and Don'ts.

This article will provide a framework for producing immersive 360-degree videos for pediatric and adult patients in hospitals. This information may be useful to hospitals across the globe who may wish to produce similar videos for their patients. Advancements in immersive 360-degree technologies have allowed us to produce our own "virtual experience" where our children can prepare for anesthesia by "experiencing" all the sights and sounds of receiving and recovering from an anesthetic.

Radiologic-Pathologic Correlation of Extranodal Extension in Patients With Squamous Cell Carcinoma of the Oral Cavity: Implications for Future Editions of the TNM Classification.

Purpose: To evaluate the accuracy and prognostication of the presence of radiologic extranodal extension (rENE) versus pathologic extranodal extension (pENE) in patients with oral cavity squamous cell carcinoma (OSCC).

Methods And Materials: A retrospective review was conducted for all newly diagnosed OSCC patients who underwent neck dissection in our institution from 2010 to 2015 with available records of preoperative computed tomography or magnetic resonance imaging. Two head and neck neuroradiologists reviewed the presence of rENE (defined as ill-defined lymph node borders) on imaging independently, being blinded regarding the pathology report.

Concurrent-Adjuvant Chemoradiation Therapy for Stage III-IVB Nasopharyngeal Carcinoma-Exploration for Achieving Optimal 10-Year Therapeutic Ratio.

Purpose: This is an updated combined analysis of 2 randomized studies (NPC-9901 and NPC-9902 trials) to evaluate the 10-year outcome attributed to the addition of concurrent-adjuvant chemotherapy for advanced locoregional nasopharyngeal carcinoma (NPC).

Patients And Methods: Eligible patients with stage III-IVB nonkeratinizing NPC were randomly assigned to radiation therapy alone (RT: 218 patients) or chemoradiation therapy (CRT: 223 patients) using 3 cycles of cisplatin (100 mg/m) concurrent with RT, followed by 3 cycles of cisplatin (80 mg/m) and fluorouracil (1000 mg/m/day for 4 days). All of the patients were irradiated with conventional fractionation to ≥66 Gy.
