‘Paradoxical’ data show routine imaging lacks benefit for head and neck cancer survivors

Source: www.healio.com Author: Matthew Shinkle Key takeaways: Researchers saw no statistical difference between patient groups with respect to treatment outcomes. Larger studies are needed to further evaluate this study’s findings. Compared with expectant management, imaging-based surveillance did not improve outcomes among patients in remission after completion of primary radiation therapy for head and neck cancer, according to data published in JAMA Network Open. Although imaging “in the context of clinical suspicion” for this specific patient population is common and typically beneficial, according to researchers, the results of this study show that such a practice is not valuable for asymptomatic patients. “The results of the present study, while seemingly paradoxical, are consistent with those of others which have failed to demonstrate a benefit to surveillance imaging among patients who have successfully completed treatment for head and neck cancer,” Allen M. Chen, MD, MBA, professor and chair of the department of radiation oncology at University of California, Irvine, Chao Family Comprehensive Cancer Center, and researchers wrote. Researchers conducted a retrospective, comparative effectiveness review to evaluate the potential benefit of surveillance imaging among asymptomatic patients with head and neck cancer currently in remission following completion of chemoradiation. The study included 340 adults (59% men; 43% white) who had achieved a complete metabolic response to initial treatment for newly diagnosed squamous cell carcinoma of the head and neck between January 2014 and June 2022. Researchers defined surveillance imaging as the acquisition of a PET with CT, MRI or CT of the head and neck [...]

Medical Mysteries: How a sore throat led to life-threatening bleeding

Source: www.washingtonpost.com Author: Sandra G. Boodman A Florida man spent months consulting doctors baffled by stabbing pain that radiated to his neck and shoulder. For more than a year, Arthur L. Kimbrough had done everything he could think of to find out what was causing the stabbing sensation that radiated from his throat to his neck and down his left shoulder. He had seen anesthesiologists, an ear, nose and throat doctor, a neurologist and neurosurgeons in Florida and Maryland; undergone tests and scans; and taken a variety of drugs that failed to alleviate the intensifying pain that baffled his doctors. It wasn’t until February 2022, after Kimbrough suffered a life-threatening hemorrhage in a hospital waiting room, that the cause was finally identified. Two years later, Kimbrough, now 76, attributes his survival to being in the right place at the right time. He says he feels lucky to be alive and is not angry his illness wasn’t diagnosed earlier. Doctors “missed some things clearly, [but] it wasn’t because they weren’t looking,” said Kimbrough, an executive coach who lives in the Florida Panhandle and owns funeral homes and cemeteries in Florida and Mississippi. “They were very responsive.” “The blinders we had on was that it turned out to be the fundamentally wrong place to be looking,” he said. Unusual sore throat Kimbrough first noticed the pain — a tender spot under the left side of his tongue in the back of his mouth — in mid-December 2020. It didn’t seem like a [...]

Revolutionary cancer tool can halve time some patients need radiotherapy

Source: www.nzherald.co.nz Author: Joe Pinkstone, Daily Telegraph UK A revolutionary cancer tool that can halve the time some patients need to be subjected to radiotherapy has been developed by British experts and is 99.9 per cent accurate. Head and neck cancers are notoriously tricky to tackle as the tumour and the patient's face often change shape during treatment due to significant weight loss. More than 12,000 people in the UK are diagnosed with head or neck cancer every year and the treatment involves being blasted with radiation to shrink a tumour while the patient lies motionless inside a mask that protects healthy tissue. "When I started training, we basically laid someone down on the bed, put a plastic mask on them and took some X-rays from the front and the side," Prof Kevin Harrington, head of radiotherapy and imaging at the Institute of Cancer Research and a consultant oncologist, told The Telegraph. "We would then blast away at them every day for six or seven weeks, treating the same area irrespective of the fact that during the treatment the patient would lose up to 10 per cent of their body weight. "Their body would shrink, the shape of the area we were radiating would shrink and as they subsided and lost weight the position of their head would slightly change and we wouldn't adjust one iota to that, we just carried on the way we were." In an ideal world, Harrington said, scans would be done every day to create [...]

Two markers help predict head and neck cancer prognosis

Source: labblog.uofmhealth.org Author: news release, University of Michigan Health Rogel Cancer Center A new study from the University of Michigan Health Rogel Cancer Center finds circulating tumor DNA, or ctDNA, levels can predict as early as two weeks after starting treatment which patients are likely to have good outcomes. At the same time, specialized MRI and PET scans two weeks after starting chemoradiation also correlated with outcomes. “Rates of throat cancer have steadily increased in recent years, driven by HPV infections, fueling the need for biomarkers to help guide treatment decisions, especially for locally advanced disease,” said senior study author J. Chad Brenner, Ph.D., associate professor of otolaryngology at Michigan Medicine. “Quantitative imaging of metabolism, local blood volume density and cell density from PET and MRI scans have shown both prognostic value in predicting treatment outcome as well as utility in selecting patients for additional focal radiation treatment,” said study author Yue Cao, Ph.D., professor of radiation oncology and radiology at Michigan Medicine. The researchers conducted a randomized trial of patients with stage 3 oropharyngeal squamous cell carcinoma. In total, 93 patients had imaging and 34 also had blood tests before starting chemoradiation and again at two, four and seven weeks after treatment. The study found that HPV ctDNA clearance at two weeks, but not at four weeks, predicted outcomes. The metabolism, local blood density and cell density before radiation therapy or at two weeks after starting treatment predicted outcomes as well. These early predictor biomarkers could help determine which [...]

Tiny cancer tracers could boost survival rates

Source: www.bignewsnetwork.com/ Author: PanArmenian.Net staff Nanoparticles that can detect complex cancer cells and potentially improve five-year survival rates are headed for human trials. South Australian company Ferronova has developed the nanoparticles that are designed to identify early stage tumor and related cancer cells, Medical Xpress says. Ferronova Chief Executive Stewart Bartlett said the tiny cancer tracers were expected to be trialled on oral cancer patients at the Royal Adelaide Hospital in April 2020, pending key approvals. Bartlett said once Ferronova's polymer-coated iron oxide nanoparticles were injected into patients they would show up on an MRI within about 15 minutes. 'The way they work in cancer is they're designed to be detected around a solid tumor' he said. 'They'll actually be picked up by your lymphatic system as a foreign body and follow the same pathway as any cancer spread from a primary tumor would follow. 'If you can actually know where those particles are going you can also determine where the cancer would have gone.' Ferronova was spun out of a nanoparticles research collaboration between the University of South Australia and New Zealand's Victoria University, with backing from IP investors Powerhouse Ventures and UniSA Ventures. Bartlett said preclinical trials at the Mawson Lakes lab had given the company confidence to use the particles on humans. He said the treatment was expected to be 90 percent accurate. 'We've added a molecule to the particles so they go to the first lymph node and they are retained in the first lymph node, [...]

Head and neck cancer: Getting a diagnosis of head and neck cancer

Source: www.curetoday.com Author: staff Meryl Kaufman, M.Ed., CCC-SLP, BRS-S, and Itzhak Brook, M.D., M.Sc., board members of the Head and Neck Cancer Alliance, discuss which symptoms should lead one to seek a diagnosis of head and neck cancer and which tests are available to aid in evaluation. Transcript: Meryl Kaufman, M.Ed., CCC-SLP, BRS-S: When we talk about the HPV-related cancers, those are primarily in the oropharynx, which is the tongue base and the tonsil. But the traditional cancers typically can also involve the tongue, the lips, the floor of the mouth, the jaw, the gums and the hard palate. And the pharynx; that includes the nasopharynx behind the nose. We’ve addressed the oropharynx but also the hypopharynx, near the larynx. And in your case, laryngeal cancer that involves the larynx, the voice box, and the epiglottis. So, head and neck cancers can occur in any of those places. Can you talk about some of the signs and symptoms people can look out for in those areas? Itzhak Brook, M.D., M.Sc.: Well, the important signs that are common to oral cancers are having a sore throat, a feeling that you cannot swallow and difficulty in swallowing. In advanced stages, it can interfere with breathing. If you have increased lymph glands in the neck and are also feeling like a lump or something is stuck in your mouth, those could be a sign. Sometimes they have symptoms such as pain in the ear or pain in the throat. And there are specific [...]

An artistic representation of cancer

Source: www.vueweekly.com Author: Stephan Boissonneault Obstructed by Jude Griebel // Stephan Boissonneault One of the most terrifying phrases known to our current human existence is “you have cancer.” Those three words can break a person. “I would describe it as a terrible cyclone of information,” says head and neck cancer patient Kimberly Flowers. “You’re surrounded by all these medical teams, all these procedures and appointments, and you’re expected as [a] patient to make the best informed decisions while you’re in a state of emotional trauma. It’s just a whirlwind of confusion.” With their project and exhibition See Me, Hear Me, Heal Me, clinicians, researchers, patients, and artists aim to recreate that initial confusion and the universal experience of head and neck cancer with multiple works of art. “I thought art was the best way to express this because art presents an effective and visceral understanding to the experience,” head researcher of the project Dr. Minn Yoon says. Yoon, being an assistant professor with the School of Dentistry at the University of Alberta, initially started the project by interviewing patients with head and neck cancer. “My research has to do with the oral health of vulnerable populations, and patients with head and neck cancer fall into that category,” Yoon says. “I wanted to get a sense of what these people actually go through and how their lives change after learning they have head and neck cancer.” After an interview with a patient who had undergone surgery to reconstruct her [...]

Imaging method has potential to stratify head and neck cancer patients

Source: www.eurekalert.org Author: press release Manchester researchers have identified a potential new way to predict which patients with head and neck cancer may benefit most from chemotherapy. These patients commonly receive pre-treatment induction chemotherapy, before either surgery or radiotherapy, to reduce the risk of disease spread. However the effectiveness of such treatment is reduced in tumours with poor blood flow. Previous studies have shown that CT scans can be used to assess tumour blood flow. Now researchers at The University of Manchester and The Christie NHS Foundation Trust - both part of the Manchester Cancer Research Centre - have explored the use of MRI scans in predicting which patients would benefit from induction chemotherapy. Professor Catharine West, who led the study, said: "It's also important to identify those patients who are unlikely to respond to induction therapy so that we can skip ahead in the treatment pathway and offer them potentially more effective treatments and hopefully improve their outcome." The team used an imaging technique known as dynamic contrast-enhanced MRI (DCE-MRI), where a contrast agent tracer is injected into a patient's vein whilst they have a series of MRI scans taken. This allows scientists and doctors to investigate the blood flow and vessel structure of a patient's tumour. They found that the blood flow of a patient's tumour before they received induction therapy could predict response to treatment. In a paper recently published in the journal Oral Oncology, the group report that those with high tumour blood flow were more [...]

Imaging technique identifies early metastasis in lymph nodes

Source: www.newswise.com Author: National Institute of Biomedical Imaging and Bioengineering NIBIB-funded researchers have developed a highly sensitive and accurate imaging technique for non-invasive screening of lymph nodes for metastatic cancer. Current practice calls for invasive surgical biopsies to determine whether deadly metastatic cancer cells have invaded the lymph nodes. The new imaging technique – so far tested in mice – offers a rapid and effective tool to noninvasively identify very small numbers of these cells, known as micrometastases, thus detecting cancer’s spread at its earliest stages, which is critical for timely treatment. The work, developed at the University of Texas at Austin and the University of Texas MD Anderson Cancer Center, is reported in the October issue of Cancer Research. The technique uses an imaging approach known as ultrasound-guided photoacoustics combined with nanosensors designed to target and identify metastatic cells in lymph nodes. Richard Conroy, Ph.D., Director of the NIBIB Program in Molecular Imaging elaborates on the technology’s potential: "This work is an excellent example of the development of a cutting edge technology that works very well in an experimental system but also has great potential to change the way we monitor and diagnose cancer metastasis. Identifying the accumulation of cells early in the process with some molecular characterization offers the opportunity for more targeted and effective treatment and fewer side effects.” More than 90% of cancer deaths can be attributed to metastases either directly or indirectly. In current clinical practice, an invasive surgical procedure called sentinel lymph node (SLN) [...]

UK researchers improve comfort levels for cancer patients by 3D printing radiotherapy body molds

Source: 3dprint.com Author: Bridget Butler Millsaps Cancer patients undergoing brain or head and neck radiotherapy are required to be immobilized, which is certainly not always popular with those undergoing the procedure, who may already be suffering from anxiety. To make things worse, in order to be immobilized completely during the procedure, it is crucial that they are wearing a fitted mold to prevent motion. Having the mold made is a whole process in itself before the procedure can begin. In a recent study produced by the Journal of Radiotherapy in Practice, over half of the patients describe the process of having a mold made as ‘horrific.’ Many of them also described the process as ‘uncomfortable.’ Topping that off with molded shells that quite often do not fit appropriately, the anxiety levels are heightened for patients — enough so that researchers centered their study around the creation of molded shells through 3D printing that could be created from data conveniently already existing in the form of a CT scan. The process would increase the comfort level for the patient and save a great deal of time in preparing a molding. Radiotherapy is a type of cancer treatment which uses high-energy rays to zap cancer cells. The procedure has to be precisely aimed directly at specific areas to have effect, and it’s not a procedure anyone wants immediately repeated; therefore, It’s important to have the head shell or molding during radiotherapy because the patient must lie still. The mold or shell holds the [...]
