Researchers take head and neck cancer by the throat

Source: www.brisbanetimes.com.au Author: Stuart Layt Research has identified more weak spots in a deadly type of head and neck cancer that it is hoped will lead to more effective treatments. Oropharyngeal cancer can affect the base of the tongue, the tonsils, soft palate and parts of the throat, and almost half of all cases in Australia are caused by the human papillomavirus (HPV). Current immunotherapies target two protein receptors on the cancer; however, they have had mixed success. Lead researcher Professor Rajiv Khanna from QIMR Berghofer said they had identified four more spots on the genome of the cancer that they believed could be targeted by immunotherapy. “Everybody has been trying to make immunotherapies that target those two antigens, but what we have found is that while those two are important, we were ignoring some of the other antigens,” Professor Khanna said. “We took immune cells out of our patients and effectively asked them what they could “see” other than [the two proteins] E6 and E7, and actually they could see others.” The study analysed immune cells taken from 66 oropharyngeal cancer patients at the Royal Brisbane and Women’s Hospital and the Princess Alexandra Hospital. Co-lead author Professor Sandro Porceddu, the director of radiation oncology research at the Princess Alexandra Hospital, said they were now developing therapies based on the research. “We’re already working on developing better killer T-cell immunotherapies that recognise all, or a combination, of these proteins,” Professor Porceddu said. “Different combinations of the proteins are present on [...]

Towards the early detection of oral cancers

Source: pursuit.unimelb.edu.au Authors: Dr Tami Yap and Professor Michael McCullough, University of Melbourne If you noticed a new dark spot on your shoulder or changes in an old mole – you would know to get it checked out. But would you know if you had a skin cancer in your mouth? As our population ages, the diagnosis of oral cancer is increasing. Globally, this devastating cancer affects 750,000 people and has a five-year mortality rate of approximately 50 per cent if not detected and treated early. The insidious nature of oral cancer means it is often detected at a later stage; up to half of people who are diagnosed with oral cancer have large tumours as oral cancer is often painless and unseen. A further challenge is the limited tools to detect and monitor potential oral cancers and skin lesions over time; this forces clinicians to remove suspicious lesions by scalpel biopsy and assess pathology. A new research project aims to identify individuals who are likely to develop oral cancer, without invasive biopsies. The Melbourne University Dental School has partnered with Victorian company OptiScan, to improve screening and early diagnosis of oral cancer. The project is led by our team at the Melbourne Dental School and uses Optiscan’s state-of-the-art confocal laser endomicroscope (CLE). Known as InVivage ™, the hand-held microscope uses a laser light and confocal optics to painlessly perform “digital biopsies”. THE TECHNOLOGY OF CANCER DETECTION Oral cancer can have a devastating impact on a person’s life – removing [...]

NSAID use may improve overall survival during chemoradiation for patients with HNSCC

Source: www.cancernetwork.com Author: Hannah Slater This study demonstrated a possible advantage in overall survival for patients taking NSAIDs during chemoradiation for head and neck squamous cell carcinoma. A study published in JAMA Network Open suggested a possible advantage in overall survival (OS) for patients taking nonsteroidal anti-inflammatory drugs (NSAIDs) during chemoradiation for head and neck squamous cell carcinoma (HNSCC). However, researchers suggested that future studies evaluating this association are warranted. “This large, retrospective cohort study suggests a significant association with improved OS for patients with HNSCC taking NSAIDs during definitive CRT,” the authors wrote. “While the change in LC with NSAID use was not significant, future studies should continue to evaluate this possibility.” Overall, 460 patients with HNSCC who were treated with chemoradiation therapy (CRT) at a single institution between January 1, 2005 and August 1, 2017 were included in the study, including 201 patients (43.7%) who were taking NSAIDs during treatment. Patient and tumor characteristics included age, race/ethnicity, smoking status, alcohol use, comorbidities (respiratory, cardiovascular, immune, renal, endocrine), disease stage, human papillomavirus (HPV) status, and treatment duration. On univariate analysis, NSAID use (hazard ratio [HR], 0.63; 95% CI, 0.43-0.92; P = 0.02) was associated with better OS. Moreover, on Cox regression analysis, after backward selection adjustment for possibly confounding factors such as age, smoking status, primary tumor site, human papillomavirus status, diabetes, stroke, and hyperlipidemia, NSAID use continued to be significantly associated with better OS (HR, 0.59; 95% CI, 0.38-0.90; P = 0.02). Even further, at 5 years NSAID [...]

Parking fees at cancer treatment centers can substantially impact costs of care

Source: www.healio.com Author: John DeRosier Parking costs at cancer treatment centers — including those with the highest standard of care — can be a source of financial toxicity for patients and caregivers, according to a research letter published in JAMA Oncology. “When my husband was treated for cancer, we paid over $15 a day for parking,” Fumiko Chino, MD, radiation oncologist at Memorial Sloan Kettering Cancer Center, told Healio. “These costs were just a small fraction of our total costs for his care, but they seemed unusually cruel. I felt like we were being nickeled-and-dimed when we were at our most vulnerable. “Many of my patients have told me similar stories; for some of them, parking costs can determine whether they will participate in a clinical trial or will get the recommended treatment for their cancer,” Chino added. Chino and colleagues obtained parking fees from the 63 NCI-designated cancer treatment centers through online searches or phone calls between September and December 2019 to determine parking costs for the treatment duration of certain cancers. Researchers documented city cost-of-living score — with New York City as the base city with a score of 100 — median city household income, center address transit score (0-24 = minimal transit options; 90-100 = world-class public transportation) and discount availability. They used a zero-inflated negative binomial model to evaluate associations between parking costs and city variables, and Pearson correlation for binary variables. Researchers estimated parking costs for treatment of node-positive breast cancer (12 daily rates plus [...]

Perceptions of telemedicine among head and neck cancer patients

Source: www.docwirenews.com Author: Kaitlyn D’Onofrio The use of telemedicine has surged amid the COVID-19 pandemic, and it is likely to continue beyond the pandemic. It is important to understand how patients feel about telemedicine, and a full understanding cannot be ascertained through questionnaires. The subject of telemedicine and its perception among head and neck cancer patients was the topic of a recent study. “The implementation of telemedicine is in general a disruptive process for both the physician and the patient. Throughout this transition, patient satisfaction is an important health care quality metric to study,” the researchers wrote. “While [surveys] are important to capture overall attitudes and information regarding the feasibility of video-based telemedicine visits, survey ranking systems do not capture the nuances of the patient experience.” The present study included established patients who participated in video-based visits with an otolaryngology-head and neck surgery faculty member between March 25 and April 24. In addition to complete a patient satisfaction questionnaire (Telehealth Usability Questionnaire [TUQ]), patients took part in an unstructured telephone interview focused on their perceptions of telemedicine during the COVID-19 pandemic. Charts were retrospectively reviewed to collect patients’ demographic, disease, and treatment information. Telemedicine: Good for Accessibility, Most Useful for Established Patients A total of 100 patients completed the TUQ, and 56 also provided open-ended comments. The mean patient age was 61 years, and most patients (60.7%) were male. About a quarter of patients (n=13) talked about their experience leading up to the telemedicine visit; themes that emerged included anxiety [...]

Jay Aston, singer: ‘I have a leg scar and one on my neck, but it’s a small price to pay for life’

Source: www.belfasttelegraph.co.uk Author: Gabrielle Fagan Jay Aston says she no longer stresses about "silly little things". After being diagnosed with mouth cancer in 2018, the former Bucks Fizz star was left wondering whether she would ever sing again - or even survive. The experience rocked her world. But Aston, part of the original band that stormed to victory in the 1981 Eurovision Song Contest and went on to sell millions of records, is still performing with Mike Nolan and Cheryl Baker in The Fizz, a new version of the group. Before lockdown hit, they'd been busy touring and promoting their latest album, Smoke And Mirrors. The enforced break has given her time to reflect on the "incredibly tough" two-year journey, which "made me re-evaluate my life", says Aston. "Surviving an experience like that makes you realise the simple things and pleasures you took for granted. "We all get so upset about minor things and miss the fact that whatever's happening, if you're here it is a good day." Aston (59) who's among a host of celebrities taking part in The Smiling Sessions - online sing-alongs to entertain care homes residents and isolated elderly people, - recalls the moment doctors revealed she had cancer. "The whole thing was such a shock and completely devastating. Also I had no idea what effect the surgery would have on my voice," she recalls. "I'm from a show-business family and singing and dancing is in my DNA and part of my identity, and to have [...]

Cell by cell in focus

Source: www.biophotonics.world Author: Sven Döring Progress can be measured in two steps in Tobias Meyer's laser laboratory and can be seen at a glance. In the background is a silver trolley, on top of it two black boxes and a monitor. The matt black compact device on the optical table in front of it is not even a fourth of it in site. Two Medicars, version 2015 and version 2019: a compact microscope for rapid cancer diagnosis during surgery. "Good news from German cancer research" was the announcement by the German government in August 2019, referring to the "precision through laser light" with which the microscope researched at Leibniz IPHT makes cancerous tissue visible, enabling surgeons to remove tumors even more precisely in the future. The black box contains a light-based tool that can be used to examine the chemical and morphological composition of the tissue. This information is evaluated with artificial intelligence and immediately indicates whether the tumor has been completely removed – in other words, whether the operation was successful. Tobias Meyer and his team from Leibniz IPHT, Friedrich Schiller University Jena, Jena University Hospital and the Fraunhofer Institute for Applied Optics and Precision Engineering are already continuing their research. They are combining the imaging procedure with a minimally invasive surgical precision tool: for laser-based microsurgery – and a new way to treat cancer in a gentle way. "Our vision," as Scientific Director Jürgen Popp describes it, "is to use light not only to identify the tumor, but [...]

Should we be drinking less?

Source: www.nytimes.com Author: Anahad O’Connor Can a daily drink or two lead to better health? For many years, the federal government’s influential dietary guidelines implied as much, saying there was evidence that moderate drinking could lower the risk of heart disease and reduce mortality. But now a committee of scientists that is helping to update the latest edition of the Dietary Guidelines for Americans is taking a harder stance on alcohol. The committee said in a recent conference call that it plans to recommend that men and women who drink limit themselves to a single serving of wine, beer or liquor per day. Do not drink because you think it will make you healthier, the committee says: It won’t. And it maintains that drinking less is generally better for health than drinking more. That message is a departure from previous guidelines, which since 1980 have defined “moderate” drinking as up to two drinks a day for men and one for women. Government agencies have also long defined a standard drink as 12 ounces of regular beer, five ounces of wine, or one and a half ounces of distilled spirits (40 percent alcohol), amounts often exceeded in Americans’ typical “drink.” Between 1990 and 2010, many editions of the guidelines, which are updated every five years, discouraged heavy drinking and warned pregnant women and people with certain medical conditions not to drink. But they also noted that moderate drinking was linked to fewer heart attacks and lower mortality. The 2010 guidelines mentioned [...]

Surgery, radiation yield similar efficacy for early squamous cell carcinoma of lip

Source: www.healio.com Author: Earl Holland Jr. Both surgery and radiation therapy were beneficial methods of treating early-stage lip squamous cell carcinoma, according to findings presented at the American Academy of Dermatology virtual meeting. Kevin Phan, MD, of the dermatology department at Liverpool Hospital, Sydney, Australia, and Mahmoud Dibas, MD, of Sulaiman Al Rajhi Colleges, College of Medicine, Saudi Arabia, sought to examine the survival rates in low-stage lip squamous cell carcinoma (SCC) between patients who had surgery alone and patients who had radiation therapy alone. “Squamous cell carcinoma of the lip composes 25% to 30% of all oral cancers,” the authors wrote. “Lip SCC is often detected at an early stage, due to the highly visible location and slow growth pattern.” Results from the Surveillance, Epidemiology, and End Results database between 2010 and 2014 were analyzed. Overall survival and cancer-specific survival were measured. The researchers identified 900 patients with early-stage lip SCC who had received either radiation alone (36 patients) or surgery alone (864 patients). Patients who underwent surgical procedures had better overall survival and cancer-specific survival rates compared with patients who had radiation alone, the study found. The treatment modality did not have a significant effect on either survival rate; the radiation-alone group had an adjusted hazard ratio of 1.94 (95% CI; 0.83-4.53), while the surgery-alone group had an adjusted hazard ratio of 1.04 (95% CI; 0.07-15.55). “Our results support the notion that surgery and [radiation therapy] appear to be equally effective in treating early-stage lip SCC,” the researchers [...]

Engineered killer immune cells target tumours and their immunosuppressive allies

Source: medicalxpress.com Author: eLife staff Scientists have engineered natural killer immune cells that not only kill head and neck tumor cells in mice but also reduce the immune-suppressing myeloid cells that allow tumors to evade the immune response, according to a new study in eLife. The engineered cell therapy could be used as an alternative approach for treating cancer in patients for whom previous immunotherapy based on the activation of T cells has failed. These findings are reported by researchers at the U.S. National Institutes of Health (NIH) in Bethesda, Maryland. In recent years, treatments called T-cell therapy or CAR-T cell therapy have been approved to treat blood cancers, and many others are now in development for other forms of cancer. However, these T-cell therapies rely on the ability to reprogram a patient's own T cells to express a chimeric antigen receptor (CAR) that targets tumor cells. This process of reprogramming a patient's own T cells is expensive and laborious. High affinity natural killer cells (haNKs) represent potential 'off-the-shelf' cell therapies that do not rely on reprogramming a patient's own immune cells. The same cells could be produced in mass and potentially given to anyone. But the presence of immune-suppressing myeloid cells in the tumor microenvironment remains a barrier to effective immunotherapy, including haNK cell-based treatment. To address this barrier, researchers from the NIH's National Institute on Deafness and Other Communication Disorders (NIDCD) and National Cancer Institute have utilized haNKs expressing a CAR that targets a molecule called programmed death [...]
