Mayo Clinic Minute: Innovative technology to treat head and neck cancers

Source: www.telegraphherald.com Author: Deb Balzer, Mayo Clinic News Network In the U.S., HPV is linked to about 70% of throat and mouth cancers. And more than 70% of those cancers are diagnosed in men, according to the Centers for Disease Control and Prevention. Treatment for throat and mouth cancers, also referred to as oropharyngeal or head and neck cancers, depends on location and stage of the cancer as well as other factors. Dr. Phillip Pirgousis, a Mayo Clinic head and neck surgeon, says patients now have safer, less invasive surgical treatments for head and neck cancers available to them thanks to innovative technology. “The tonsils in the back of the throat and the lymph node tissue in the back of the tongue,” Pirgousis says. And cancers in these two locations can be a challenge. “Many of the challenges are often related to the location of the primary tumor because the throat and voice box area are very difficult to get access to,” he says. That’s where innovation with robotics allows for better tumor visualization, better lighting and better outcomes in terms of complete tumor removal. “We’re talking about big, open surgeries versus minimally invasive surgeries where we can access these difficult locations with making facial incisions,” he says. “And having less impact on breathing, speaking, swallowing and communicating. The surgical robot has improved the ability for us to not only completely remove tumors, but to remove them safely,” Pirgousis says.

Researchers identify new metric to articulate relationship between nerve density and oral cancer

Source: www.bitemagazine.com.au Author: staff US researchers have identified a new metric to articulate the relationship between nerve density and oral cancer. The study—by researchers at the University of Michigan Rogel Cancer Center and the School of Dentistry, and published in Clinical Cancer Research—investigated normalised nerve density to translate previous mechanistic studies into a context that could be used in the clinic. “We are recognising more and more that there’s a very dynamic interaction between nerves and cancer cells in the tumour microenvironment,” senior author Dr Nisha D’Silva said. The team looked at how the density of nerves within a tumour tied with the tumour’s growth. The oral cavity has several regions, each with different functions. The way each area receives nerves is distinct; the nerves in the inside of the cheek have a different role and are fewer than nerves on the tongue. Given these variations, looking at nerve density of the tumour without considering the normal innervation of the different areas in the oral cavity and each individual’s variation to assess whether a tumour is aggressive leaves an inaccurate picture. To account for this, the team created a standardised metric for nerve density to clarify the variation in distribution of nerves in the oral cavity, called normalised nerve density, and showed its importance in tumour progression. Most of the work was done with human tissue, and the team then validated the findings using a mouse model. They used adjacent tissue to compare and determine a ‘normalised’ density for different [...]

These tiny worms can smell cancer in your pee

Source: www.euronews.com Author: Aylin Elci N-Nose uses nematode worms and urine to screen cancer in patients. - Copyright Courtesy Hirotsu Bio Science Scientists say the humble roundworm can sniff out cancer cells and could help save lives by spotting tumours at a very early stage. Japanese start-up Hirotsu Bio Science is shaking up early cancer screening with the help of an unlikely ally: tiny worms. Instead of relatively invasive and expensive methods such as endoscopies, surgeries or blood tests, the company only needs a urine sample to detect early-stage cancer (0 to 1) in patients. “We usually go to hospital when we start feeling something strange in our body,” Eric di Luccio, Chief Technology Officer at Hirotsu Bio Science, told Euronews Next. “That’s when the cancer is detected, but it’s usually at an advanced stage and the odds of getting out of it alive will depend on the cancer, but sometimes it's bad,” he added, calling primary cancer screening in urine samples a “game changer”. While cancer is “detected” in patients who have symptoms, screening, on the other hand, is conducted on healthy patients. According to a recent report by the American Cancer Society, both of these actions are among the reasons why deaths linked to the disease are decreasing. Nobel Prize worms and smelly cancers Hirotsu Bio Science’s flagship product, N-Nose, is a non-invasive invasive cancer screening process that uses tiny worms’ olfactory sense to find cancer in urine samples.

Multidisciplinary treatment approaches for oral cavity cancer

Source: dailynews.ascopubs.org Author: Mindy Tanzola, PhD An Education Session at the 2023 ASCO Annual Meeting will focus on the treatment of oral cavity cancer, one of the most common types of head and neck cancer worldwide. The session will feature experts from medical, radiation, and surgical oncology to address all 3 treatment modalities, said Session Chair Ali Hosni, MBBCh, MSc, PhD, of Princess Margaret Cancer Center in Canada. The session will take place on June 4. Although oral cavity cancer is diagnosed in more than 300,000 individuals worldwide each year,1 it receives less attention than other subsets of head and neck cancer, Dr. Hosni said, highlighting a need for education. In addition, oral cavity cancer often involves all 3 treatment modalities, which means there is a need for collaborative multidisciplinary care that also integrates the patient into treatment planning. Role of Sentinel Lymph Node Biopsy In his update on surgical approaches for oral cavity cancer, Stephen Y. Lai, MD, PhD, FACS, a head and neck cancer surgeon at The University of Texas MD Anderson Cancer Center, will first discuss the role of sentinel lymph node biopsy (SLNB) for these patients. Dr. Lai explained that lymph node metastases are sometimes found in patients with early-stage oral cavity cancer (T1-2) who are thought to be node-negative based upon imaging studies and clinical examination. However, evidence has shown that active management through elective neck dissection is associated with higher rates of overall survival and disease-free survival versus “watchful waiting” and therapeutic neck dissection.2 [...]

What is the role of a Speech Language Pathologist in an acute care setting?

Source: www.lhsc.on.ca Author: London Health Sciences Centre A Speech Language Pathologist (S-LP) assesses and manages swallowing and communication. Since these activities are performed by the same set of muscles, an S-LP is able to provide support for both functions. Communication functions include speech, voice, language, and cognitive-communication. S-LPs support expressive abilities (verbal and non-verbal communication) as well as receptive abilities (understanding what other people are saying). We provide low-tech and high-tech communication aids when appropriate, or refer to community services to support as needed. For swallowing, S-LPs help patients with the ability to consume solids and liquids safely and efficiently when experiencing difficulties with the muscles that support this function. “We focus on the quality of life of the patient and do our best to optimize and maximize their abilities in swallowing or communication or both,” explains Suzie Fox, Speech Language Pathologist at London Health Sciences Centre (LHSC). “We work with the patient and take into account their values and wishes so they are able to get the most out of what they eat and drink and how they communicate once they return home.” How can someone lose communication and swallowing functions? A number of conditions may impact swallowing or communication because of changes to our muscles for speaking/eating or the respiratory system. Some examples include: Neurological conditions: stroke, brain injury or tumours, or neuromuscular diseases. Medical conditions: dementia, COPD, congestive heart failure. Surgery: head and neck, esophageal, orthopedic, facial and head trauma, transplant. Cancer: head and neck cancer, brain [...]

First patient dosed with new treatment for breast cancer and other tumors in clinical trial

Source: www.curetoday.com Author: Alex Biese The first patent has been dosed in a clinical trial evaluating a new treatment for breast cancer and other solid tumors. Work is underway on a phase 1/2 trial evaluating STX-478 — an oral drug that can penetrate into the central nervous system (CNS) and inhibit mutant phosphoinositide-3-kinase alpha (PI3Kα) — as a monotherapy for tumors including breast and gynecological cancers and head and neck squamous cell carcinoma (HNSCC), as well as a monotherapy and in combination with approved agents in patients with HR+/HER2- breast cancer, according to a May 2 news release from Scorpion Therapeutics, Inc., the manufacturer behind the novel drug. With approximately 160 participants, all 18 or older with advanced solid tumors, the study launched in April. It is expected to be completed by June 2026, with the aim of evaluating the safety, tolerability, pharmacokinetics (the activity of drugs in the body) and preliminary antitumor activity of STX-478. The trial, per the announcement from Scorpion, is working to determine the safety profile of STX-478 and establish a maximum tolerated does as well as a lower optimal-biologically active dose, if appropriate, as a recommended phase 2 dose as a monotherapy for breast cancer and other solid tumor types, as well as a combination agent in PI3Kα-mutant HR+/HER-2- breast cancer. Scorpion plans to then evaluate STX-478 as a monotherapy treatment for patients with solid tumors with PI3Kα-mutations including breast cancer, gynecological cancers, HNSCC and gastrointestinal cancers. Secondary trial objectives include evaluating the pharmacokinetic profile, [...]

California bill would mandate HPV vaccine for incoming college students

Source: www.cancerhealth.com Author: Rachel Scheier and KFF Health News When she was a college freshman, Joslyn Chaiprasert-Paguio was told by a doctor she had a common sexually transmitted infection called the human papillomavirus but not to worry. Four years later, a few days before her wedding, she was diagnosed with cervical cancer, which caused complications when she became pregnant. She had a hysterectomy eight years later, after the disease returned in 2021. The 38-year-old medical journal editor of Menifee in Riverside County, California, hadn’t been immunized as a teenager because there wasn’t yet a vaccine for HPV, which causes nearly all cervical cancers and a handful of other potentially lethal forms of the disease in men and women. Now, her 10-year-old daughter, Samantha, is scheduled to get her first shot this month. “This is the only vaccine that prevents cancer,” Chaiprasert-Paguio said. [Editor’s note: The hepatitis B vaccine prevents liver cancer.] A bill pending in the California legislature would require schools to notify parents that their kids are expected to be vaccinated for HPV before entering eighth grade, as part of a push to get more children inoculated against the cancer-causing strains of the virus, theoretically before they become sexually active. AB 659 stops short of mandating the vaccine for middle schoolers, as the bill originally proposed. Lawmakers stripped out that provision without any debate, reflecting the contentious nature of school vaccine mandates even in a state with some of the nation’s strictest immunization laws. “Now is a tough time [...]

These microbes found in tumours promote cancer. What if we just kill them?

Source: www.nationalgeographic.co.uk Author: Sanjay Mishra An unfathonable number of bacteria, live in and on our bodies; most providing some benefits. Now researchers have discovered that some species of bacteria are actually protecting cancer cells. This finding could inspire new strategies to fight cancer.Photograph by illustration by Russell Kightley, Science Photo Library Most bacteria living in the human body help us thrive, but recent studies show that some infiltrate tumours, helping them grow, spread, and become more difficult for the immune system to destroy. The human body contains 100 trillion or so microbial cells, almost as many, if not more, than the number of human cells in the body. Bacteria make up most of this microbiome, living in our gut, on our skin, in the respiratory and urogenital tracts, and in mammary glands. A number of recent studies have revealed that bacteria are also present in a wide variety of tumours, where they live not only between cells but even inside them. The bacteria were thought to be taking advantage of a favourable growing environment; scientists had no idea whether these microbes could alter cancer prognosis. Now a study published recently in Nature shows that bacteria in oral and colorectal tumors can directly promote cancer by suppressing the human immune response and helping cancer cells spread more rapidly. An accompanying study published in the journal Cell Reports finds that some anticancer drugs, such as 5-fluorouracil, may be effective because they also kill the bacteria which help the tumour develop.

5 major risk factors for head and neck cancers are within your control

Source: news.llu.edu Author: Lisa Aubry, Loma Linda University Health While head and neck cancers represent a broad category for numerous cancers, a set of five controllable risk factors contribute to most head and neck cancers, says Jared Inman, MD, a head and neck surgical oncologist at Loma Linda University Health. For April’s Head and Neck Cancer Awareness Month, Inman outlines how reducing these five risks in your life can help prevent head and neck cancers. Head and neck cancers, those cancers occurring above the shoulder bones not including brain cancers, occur in the voice box, throat, tongue, mouth, sinus, nose, ear, eyes, as well as other places. Squamous cell cancers are by far the most common types of head and neck cancers, says Inman, and can happen in any location of the head and neck. Therefore, the risk factors and Inman's prevention tips pertain especially to squamous cell cancers. TOBACCO AND ALCOHOL Tobacco, which includes secondhand smoke and smokeless tobacco, is the number one stand-alone risk factor for head and neck cancers, Inman says, with alcohol consumption a close runner-up. Additionally, he says combined tobacco and alcohol use places people at a greater risk of developing these cancers than those who use tobacco or alcohol alone. Most head and neck squamous cell carcinomas of the mouth and voice box are caused by tobacco and alcohol use, according to the National Cancer Institute. “Head and neck cancers are almost always tied to smoking and drinking alcohol,” says Inman. Quitting smoking and [...]

I blamed my ulcers on college stress — until my tongue was removed

Source: nypost.com Author: Brooke Steinberg A college student with ulcers blamed it on stress from exams — but ended up needing to have the majority of her tongue removed and then reconstructed when it turned out to be cancer. Rachel Morton from Edinburgh, Scotland, started noticing ulcers on her tongue in 2019, and initially thought they were a result of stress. “When I’m a bit tired, run down or stressed with exams I seem to be a bit prone to ulcers anyway, so I kind of just put it down to that and starting university,” Morton explained. “I went to the doctor and I’d been given some pain relief tablets, Bonjela and stuff like that.” But after a year, her condition worsened. “I still had them a year later but I wasn’t too worried about it. I had so much other stuff going on in my life and it wasn’t really at the forefront of my mind,” she told Kennedy News and Media. “At the start it was a couple of ulcers, but over the course of a year they got bigger and spread, and covered the whole side of my tongue. They were really red, raw and painful.” Rachel Morton ended up needing to have her tongue removed and reconstructed when her ulcers turned out to be cancer. Kennedy News and Media Morton, now 21, was also experiencing strange symptoms such as extreme tiredness; dry, red and swollen lips; tonsil aches; and abnormal feeling in the left [...]
